2020 RAM 2500 Owners Manual - AUXILIARY DRIVING SYSTEMS



AUXILIARY DRIVING SYSTEMS

The Blind Spot Monitoring (BSM) system uses two radar-based sensors, located inside the tail- lights, to detect highway licensable vehicles (automobiles, trucks, motorcycles, etc.) that enter the blind spot zones from the rear/front/ side of the vehicle.

 

Rear Detection Zones

When the vehicle is started, the BSM warning light will momentarily illuminate in both outside rearview mirrors to let the driver know that the system is operational. The BSM system sensors operate when the vehicle is in any forward gear or REVERSE and enters standby mode when the vehicle is in PARK.

The BSM detection zone covers approximately one lane width on both sides of the vehicle 12 ft (3.8 m). The zone length starts at the outside rear view mirror and extends approximately 10 ft (3 m) beyond the rear bumper of the vehicle. The BSM system monitors the detec- tion zones on both sides of the vehicle when the vehicle speed reaches approximately 6 mph (10 km/h) or higher and will alert the driver of vehicles in these areas.

The BSM system DOES NOT alert the driver about rapidly approaching vehicles that are outside the detection zones.
The Blind Spot Monitoring (BSM) system may experience drop outs (blinking on and off) of the side mirror Warning Indicator lamps when a motorcycle or any small object remains at the side of the vehicle for extended periods of time (more than a couple of seconds).

The vehicle’s taillights, where the radar sensors are located, must remain free of snow, ice, and dirt/road contamination so that the BSM system can function properly. Do not block the taillights with foreign objects (bumper stickers, bicycle racks, etc.).

 

Radar Sensor Locations

If the system detects degraded performance due to contamination or foreign objects, a message will warn you of a blocked sensor and the warning indicators in side view mirrors will be on. The warning indicators will remain illumi- nated until blockage clearing conditions are met. First clear the taillights around the sensors of the blockage. After removing the blockage, the following procedure can be used to reset the system, cycle the ignition from ON to OFF and then back ON.

If the blockage message is still present after cycling the ignition and driving in traffic, check again for a blockage.

 

The BSM system notifies the driver of objects in the detection zones by illuminating the BSM warning light located in the outside mirrors in addition to sounding an audible (chime) alert and reducing the radio volume. Refer to “Modes Of Operation” in this section for further informa- tion.

Warning Light Location

The BSM system monitors the detection zone from three different entry points (side, rear, front) while driving to see if an alert is neces- sary. The BSM system will issue an alert during these types of zone entries.

Vehicles that move into your adjacent lanes from either side of the vehicle.

Side Monitoring

Vehicles that come up from behind your vehicle on either side and enter the rear detection zone with a relative speed of less than 30 mph (48 km/h).

Rear Monitoring

If you pass another vehicle slowly with a relative speed less than 15 mph (24 km/h) and the vehicle remains in the blind spot for approxi- mately 1.5 seconds, the warning light will be illuminated. If the difference in speed between the two vehicles is greater than 15 mph (24 km/h), the warning light will not illuminate.

Overtaking/Approaching 4

Overtaking/Passing

The BSM system is designed not to issue an alert on stationary objects such as guardrails, posts, walls, foliage, berms, snow banks, car washes etc. However, occasionally the system may alert on such objects. This is normal opera- tion and your vehicle does not require service.

The BSM system will not alert you of objects that are traveling in the opposite direction of the vehicle in adjacent lanes.

Opposing Traffic

WARNING!

The Blind Spot Monitoring system is only an aid to help detect objects in the blind spot zones. The BSM system is not designed to detect pedestrians, bicyclists, or animals. Even if your vehicle is equipped with the BSM system, always check your vehicle’s mirrors, glance over your shoulder, and use your turn signal before changing lanes. Failure to do so can result in serious injury or death.

The Rear Cross Path (RCP) feature is intended to aid the driver when backing out of parking spaces where their vision of oncoming vehicles may be blocked. Proceed slowly and cautiously out of the parking space until the rear end of the vehicle is exposed. The RCP system will then have a clear view of the cross traffic and if an oncoming vehicle is detected, alert the driver.

RCP Detection Zones

RCP monitors the rear detection zones on both sides of the vehicle, for objects that are moving toward the side of the vehicle with a minimum speed of approximately 3 mph (5 km/h), to objects moving a maximum of approximately 20 mph (32 km/h), such as in parking lot situa- tions.

 

In a parking lot situation, oncoming vehicles can be obscured by vehicles parked on either side. If the sensors are blocked by other structures or vehicles, the system will not be able to alert the driver.

When RCP is on and the vehicle is in REVERSE, the driver is alerted using both the visual and audible alarms, including reducing the radio volume.

WARNING!

Rear Cross Path Detection (RCP) is not a back up aid system. It is intended to be used to help a driver detect an oncoming vehicle in a parking lot situation. Drivers must be careful when backing up, even when using RCP. Always check carefully behind your vehicle, look behind you, and be sure to check for pedestrians, animals, other vehicles, obstructions, and blind spots before backing up. Failure to do so can result in serious injury or death.

Three selectable modes of operation are avail- able in the Uconnect System.

Refer to “Uconnect Settings” in “Multimedia” for further information.

When operating in Blind Spot Alert mode, the BSM system will provide a visual alert in the appropriate side view mirror based on a detected object. However, when the system is operating in Rear Cross Path (RCP) mode, the system will respond with both visual and audible alerts when a detected object is present. Whenever an audible alert is requested, the radio is muted.

When operating in Blind Spot Alert Lights/ Chime mode, the BSM system will provide a visual alert in the appropriate side view mirror based on a detected object. If the turn signal is then activated, and it corresponds to an alert present on that side of the vehicle, an audible chime will also be sounded. Whenever a turn signal and detected object are present on the same side at the same time, both the visual and audible alerts will be issued. In addition to the audible alert the radio (if on) will also be muted.

 

Whenever an audible alert is requested by the BSM system, the radio is also muted.

When the system is in RCP, the system shall respond with both visual and audible alerts when a detected object is present. Whenever an audible alert is requested, the radio is also muted. Turn/hazard signal status is ignored; the RCP state always requests the chime.

When the BSM system is turned off there will be no visual or audible alerts from either the BSM or RCP systems.

The BSM system will store the current operating mode when the vehicle is shut off. Each time the vehicle is started the previously stored mode will be recalled and used.

When Trailer Merge Assist is activated, Rear Cross Path is disabled.

 

When a trailer with an electric brake is connected to the vehicle, the instrument cluster display will provide a menu to allow a selection of the trailer type. There will be two options provided: Conventional and Goose/Fifth Wheel. Goose/Fifth Wheel Trailer is incompatible and when selected, the BSM system will disable until the trailer is disconnected. If the wrong option is selected, the system can be reset by either disconnecting and reconnecting the trailer harness connector or disabling then

re-enabling the Blind Spot Monitoring System in the customer settings in the Uconnect. This will prompt the trailer selection menu again to allow for the correct selection.

Trailer Merge Assist is a function of the Blind Spot Monitoring (BSM) system that extends the blind spot zone to work while pulling a trailer. Trailer Merge Assist consists of three sub func- tions:

  • Automatic Trailer Detection
  • Trailer Length Detection
  • Trailer Merge Warning

been verified. You will se uto” in the Maximum length supported by the Trailer Merge 

Blind Spot Zones With Trailer Merge Assist instrument panel cluster .

— Vehicle
— Trailer

Max Mode — When “Max Mode” is selected, the system will default to the maximum blind spot zone regardless of what size trailer is attached .

Selected setting is stored when the ignition is placed in the OFF position. To change this setting, it must be selected through the Ucon- nect Settings. Refer to “Uconnect Settings” in Assist feature is 39.5 ft (12 m). Trailer length is considered the forward most portion of the trailer hitch to the rearward most portion of the body, bumper, or ramp of the trailer.

Maximum width supported by the Trailer Merge Assist feature is 8.5 ft (2.59 m). Trailer width is measured at the widest portion of the trailer and may include wheels, tires, finders, or rails.

Fifth wheel or gooseneck trailers are not supported by Trailer Merge Assist.

“Multimedia” for further information.

There are two modes of operation for the detec- tion of the trailer length:

Automatic Mode — When “Auto Mode” is selected, the system will use the blind spot sensors to automatically determine the pres- ence and length of a trailer. The presence of a trailer will be detected using the blind spot radar within 90 seconds of forward move- ment of the vehicle. The vehicle must be moving above 6 mph (10 km/h) to activate the feature. Once the trailer has been detected, the system will default to the maximum blind spot zone until the length has Once the trailer presence has been established, the trailer length will be established (by making a 90 degree turn) and then the trailer length category (e.g. 10-20 ft (3 m to 6 m)) will be displayed. This can take up to 30 seconds after completing the turn.

During the same ignition cycle, if the vehicle is at a standstill for a minimum of 90 seconds, a new “trailer detection request” is enabled by the system once the vehicle resumes motion.

 

Trailer Length Detection

1 — Trailer Length 2 — Trailer Width 3 — Trailer Hitch

 

Trailer length will be identified and placed into one of the following categories:

Trailer length up to 10 ft (3 m) — Bli

zone will be adjusted to 10 ft (3 m) .

Trailer length between 10 ft to 20 ft (3 m to 6 m) — Blind spot zone will be adjusted to 20 ft (6 m) .
Trailer length between 20 ft to 30 ft (6 m to 9 m) — Blind spot zone will be adjusted to 30 ft (9 m) .
Trailer length between 30 ft and 39.5 ft (9 m to 12 m) — Blind spot zone will be adjusted to MAX distance .

Trailer length is determined within +/- 3 ft (1 m) of actual length. Trailers that are the same size as the category limit, 10/20/30 ft (3/6/9 m), could be subject to being placed in the category above or below the correct one.

Trailer Merge Warning is the extension of the blind spot function to cover the length of the trailer, plus a safety margin, to warn the driver when there is a vehicle in the adjacent lane. The driver is alerted by the illumination of the BSM

 

warning light located in the outside mirror on the side the other vehicle is detected. In addi- tion, an audible (chime) alert will be heard and radio volume reduced. Refer to “Modes Of Oper- ation” in this section for further information.

The Trailer Merge Alert system DOES NOT alert the driver about rapidly approaching vehicles that are outside the detection zones.
The Blind Spot Monitoring (BSM) system may experience drop outs (blinking on and off) of the side mirror warning indicator lamps when a motorcycle or any small object remains at the side of the vehicle for extended periods of time (more than a couple of seconds).
Crowded areas such as parking lots, neigh- borhoods, etc. May lead to an increased amount of false alerts. This is normal opera- tion.

 

The following regulatory statement applies to all Radio Frequency (RF) devices equipped in this vehicle:

This device complies with Part 15 of the FCC Rules and with Innovation, Science and Economic Development Canada license-exempt RSS standard(s). Operation is subject to the following two conditions:

This device may not cause harmful interfer- ence, and
This device must accept any interference received, including interference that may cause undesired operation.

Le présent appareil est conforme aux CNR d`Innovation, Science and Economic Develop- ment applicables aux appareils radio exempts de licence. L'exploitation est autorisée aux deux conditions suivantes:

l'appareil ne doit pas produire de brouil- lage, et
l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en comprom- ettre le fonctionnement.

La operación de este equipo está sujeta a las siguientes dos condiciones:

Changes or modifications not expressly approved by the party responsible for compli- ance could void the user’s authority to operate the equipment.

The Forward Collision Warning (FCW) system provides the driver with audible, visual warnings (within the instrument cluster display), and may apply a haptic warning in the form of a brake jerk, to warn the driver when it detects a poten- tial frontal collision. The warnings are intended to provide the driver with enough time to react, avoid or mitigate the potential collision.

FCW monitors the information from the forward looking sensors as well as Electronic Brake Controller (EBC), to calculate the probability of a forward collision. When the system determines that a forward collision is probable, the driver will be provided with audible and visual warn- ings as well as a possible haptic warning in the form of a brake jerk.

If the driver does not take action based upon these progressive warnings, then the system will provide a limited level of active braking to help slow the vehicle and mitigate the potential forward collision. If the driver reacts to the warn- ings by braking and the system determines that the driver intends to avoid the collision by braking but has not applied sufficient brake force, the system will compensate and provide additional brake force as required. When towing a trailer, the system will also respond to activate the trailer brakes (if equipped).

If a FCW with Mitigation event begins at a speed below 32 mph (52 km/h), the system may provide the maximum braking possible to miti- gate the potential forward collision. If the Forward Collision Warning with Mitigation event stops the vehicle completely, the system will hold the vehicle at standstill for two seconds and then release the brakes.

FCW Message

When the system determines a collision with the vehicle in front of you is no longer probable, the warning message will be deactivated.

The minimum speed for FCW activation is 3 mph (5 km/h).
The FCW alerts may be triggered on objects other than vehicles such as guard rails or sign posts based on the course prediction. This is expected and is a part of normal FCW activation and functionality.
It is unsafe to test the FCW system. To prevent such misuse of the system, after four Active Braking events within a key cycle, the Active Braking portion of FCW will be deacti- vated until the next key cycle.
The FCW system is intended for on-road use only. If the vehicle is taken off-road, the FCW system should be deactivated to prevent unnecessary warnings to the surroundings.
FCW may not react to irrelevant objects such as overhead objects, ground reflections, objects not in the path of the vehicle, stationary objects that are far away, oncoming traffic, or leading vehicles with the same or higher rate of speed.
“FCW will be disabled like ACC, with the unavailable screens.
During a FCW event when towing a trailer, your Electronic Brake system will respond, to activate the trailer brakes (if equipped).

WARNING!

Forward Collision Warning (FCW) is not intended to avoid a collision on its own, nor can FCW detect every type of potential collision. The driver has the responsibility to avoid a collision by controlling the vehicle via braking and steering. Failure to follow this warning could lead to serious injury or death.

The FCW button is located in the Uconnect display in the control settings. Refer to “Ucon- nect Settings” in “Multimedia” in the Owner's Manual for further information.

To turn the FCW system on, press the forward collision button once.

 

To turn the FCW system off, press the forward collision button once.
When the FCW is “on”, this allows the system to warn the driver of a possible collision with the vehicle in front.
When the FCW is “off” prevents the system from warning the driver of a possible collision with the vehicle in front. If the FCW is set to 4 “off”, “FCW OFF" will be displayed in the instrument cluster display.
When FCW status is set to “Only Warning” prevents the system from providing limited active braking, or additional brake support if the driver is not braking adequately in the event of a potential frontal collision.
When FCW status is set to “Warning and Braking” this allows the system to warn the driver of a possible collision with the vehicle in front using audible/visual warnings and it applies autonomous braking.
The FCW system state is defaulted to “Full On” from one ignition cycle to the next. If the system is turned off, it will reset to “Full On” when the vehicle is restarted.

The FCW sensitivity and Active Braking status are programmable through the Uconnect System. Refer to “Uconnect Settings” in “Multi- media” for further information.

Far
When the sensitivity of FCW is set to the “Far” setting and the system status is “Warning and Braking”, this allows the system to warn the driver of a possible more distant collisions with the vehicle in front using audible/visual warnings.
More cautious drivers that do not mind frequent warnings may prefer this setting.
Medium
When the sensitivity of FCW is set to the “Medium” setting and the system status is “Warning and Braking”, this allows the system to warn the driver of a possible collision with the vehicle in front using audible/visual warnings.
Near
When the sensitivity of FCW is set to the “Near” setting and the system status is “Warning and Braking”, this allows the system to warn the driver of a possible closer collisions with the vehicle in front using audible/visual warnings.
This setting provides less reaction time than the “Far” and “Medium” settings, which allows for a more dynamic driving experience.
More dynamic or aggressive drivers that want to avoid frequent warnings may prefer this setting.

If the instrument cluster displays “ACC/FCW Limited Functionality” or “ACC/FCW Limited Functionality Clean Front Windshield” momen- tarily, there may be a condition that limits FCW functionality. Although the vehicle is still driv- able under normal conditions, the active braking may not be fully available. Once the condition that limited the system performance is no longer present, the system will return to its full performance state. If the problem persists, see an authorized dealer.

If the system turns off, and the instrument cluster displays:

ACC/FCW Unavailable Service Required
Cruise/FCW Unavailable Service Required

This indicates there is an internal system fault. Although the vehicle is still drivable under normal conditions, have the system checked by an authorized dealer.

The Tire Pressure Monitoring System (TPMS) will warn the driver of a low tire pressure based on the vehicle recommended cold placard pres- sure.

The TPMS Warning Light will illuminate in the instrument cluster and a chime will sound when tire pressure is low in one or more of the four active road tires. In addition, the instrument cluster will display a graphic showing the pres- sure values of each tire with the low tire pres- sure values in a different color, or the Uconnect radio will display a TPMS message, when this occurs you must increase the tire pressure to the recommended cold placard pressure in order for the TPMS Warning Light to turn off.

The tire pressure will vary with temperature by about 1 psi (7 kPa) for every 12°F (6.5°C). This means that when the outside temperature decreases, the tire pressure will decrease. Tire pressure should always be set based on cold inflation tire pressure. This is defined as the tire pressure after the vehicle has not been driven for at least three hours, or driven less than 1 mile (1.6 km) after a three hour period. The cold tire inflation pressure must not exceed the maximum inflation pressure molded into the tire sidewall. Refer to “Tires” in “Servicing And Maintenance” for information on how to prop- erly inflate the vehicle’s tires. The tire pressure will also increase as the vehicle is driven - this is normal and there should be no adjustment for this increased pressure.

The TPMS will warn the driver of a low tire pres- sure if the tire pressure falls below the low-pressure warning limit for any reason, including low temperature effects and natural pressure loss through the tire.

The TPMS will continue to warn the driver of low tire pressure as long as the condition exists, and will not turn off until the tire pressure is at or above the recommended cold placard pres- sure. Once the low TPMS Warning Light illumi- nates, you must increase the tire pressure to the recommended cold placard pressure in order for the TPMS Warning Light to turn off. The system will automatically update and the TPMS Warning Light will turn off once the system receives the updated tire pressures. The vehicle may need to be driven for up to 20 minutes above 15 mph (24 km/h) in order for the TPMS to receive this information.

When filling warm tires, the tire pressure may need to be increased up to an additional 4 psi (28 kPa) above the recommended cold placard pressure in order to turn the TPMS Warning Light off.

For example, your vehicle may have a recom- mended cold (parked for more than three hours) placard pressure of 30 psi (207 kPa). If the ambient temperature is 68°F (20°C) and the measured tire pressure is 27 psi (186 kPa), a temperature drop to 20°F (-7°C) will decrease the tire pressure to approximately 23 psi (158 kPa). This tire pressure is sufficiently low enough to turn on the TPMS Warning Light. Driving the vehicle may cause the tire pressure to rise to approximately 27 psi (186 kPa), but the TPMS Warning Light will still be on. In this situa- tion, the TPMS Warning Light will turn off only after the tires are inflated to the vehicle’s recom- mended cold placard pressure value.

The TPMS is not intended to replace normal tire care and maintenance or to provide warning of a tire failure or condition.
If your vehicle is not equipped with the Tire Fill Alert feature the TPMS should not be used as a tire pressure gauge while adjusting your tire pressure.
Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle’s handling and stopping ability.
The TPMS is not a substitute for proper tire maintenance, and it is the driver’s responsi- bility to maintain correct tire pressure using an accurate tire pressure gauge, even if under-inflation has not reached the level to trigger illumination of the TPMS Warning Light.
Seasonal temperature changes will affect tire pressure, and the TPMS will monitor the actual tire pressure in the tire.

Example: Tire Pressure Monitoring Display

The Tire Pressure Monitoring System (TPMS) uses wireless technology with wheel rim mounted electronic sensors to monitor tire pressure levels. Sensors, mounted to each wheel as part of the valve stem, transmit tire pressure readings to the receiver module.

It is particularly important for you to check the tire pressure in all of the tires on your vehicle monthly and to maintain the proper pressure.

The TPMS consists of the following compo- nents:

Receiver module
Four Tire Pressure Monitoring sensors

 

Various Tire Pressure Monitoring System messages, which display in the instrument cluster
Tire Pressure Monitoring System Warning Light

The “Tire Pressure Monitoring Warning Light” will illuminate in the instrument cluster when tire pressure is low in one or more of the four active

road tires. In addition, the instrument cluster will display a graphic showing the pressure values of each tire with the low tire pressure values in a different color. An "Inflate to XX" message will also be displayed.

Example: Low Tire Pressure Display

 

Should this occur, you should stop as soon as possible and inflate the tires with a low pressure condition (those in a different color in the instru- ment cluster graphic) to the vehicle’s recom- mended cold placard pressure inflation value as shown in the "Inflate to XX" message. Once the system receives the updated tire pressures, the system will automatically update, the graphic display in the instrument cluster will

return to its original color, and the “Tire Pres- 4 sure Monitoring Telltale Light” will turn off. The vehicle may need to be driven for up to 20 minutes above 15 mph (24 km/h) in order for the TPMS to receive this information.

When filling warm tires, the tire pressure may need to be increased up to an additional 4 psi (28 kPa) above the recommended cold placard pressure in order to turn the Tire Pressure Moni- toring Warning Light off.

If a system fault is detected, the “Tire Pressure Monitoring Warning Light” will flash on and off for 75 seconds and then remain on solid. In addition, the instrument cluster will display a "SERVICE TPM SYSTEM" message for a minimum of five seconds and then display dashes (- -) in place of the pressure value to indi- cate which sensor is not being received.

If the ignition switch is cycled, this sequence will repeat, providing the system fault still exists. If the system fault no longer exists, the “Tire Pres- sure Monitoring Warning Light” will no longer flash, and the "SERVICE TPM SYSTEM" message will no longer display, and a pressure value will display in place of the dashes. A system fault can occur due to any of the following:

Signal interference due to electronic devices or driving next to facilities emitting the same radio frequencies as the TPM sensors.
Installing aftermarket window tinting that contains materials that may block radio wave signals.
Accumulation of snow or ice around the wheels or wheel housings.
Using tire chains on the vehicle.
Using wheels/tires not equipped with TPM sensors.

A system fault may occur due to an incorrect TPM sensor location condition. When a system fault occurs due to an incorrect TPM sensor location, the “Tire Pressure Monitoring Warning Light” will flash on and off for 75 seconds and then remain on solid. The system fault will also sound a chime. In addition, the instrument cluster will display a “Tire Pressure Temporarily Unavailable” message in place of the tire pres- sure display screen. If the ignition switch is cycled, this sequence will repeat, providing the system fault still exists. If the system fault no longer exists, the “Tire Pressure Monitoring Warning Light” will no longer flash and the tire pressure display screen will be displayed showing the tire pressure values the correct locations.

The non matching full size spare or compact spare tire does not have a TPM sensor. Therefore, the TPMS will not monitor the pressure in the non matching full size spare or compact spare tire.
If you install the non matching full size spare or compact spare tire in place of a road tire that has a pressure below the low-pressure warning limit, upon the next ignition switch cycle, the TPM Warning Light and a “LOW TIRE” message will remain on and a chime will sound. In addition, the graphic in the instrument cluster will still display a pressure value in a different color and an “Inflate to XX” message.
After driving the vehicle for up to 20 minutes above 15 mph (24 km/h), the TPM Warning Light will flash on and off for 75 seconds and then remain on solid. In addition, the instru- ment cluster will display a "SERVICE TPM SYSTEM" message for a minimum of five seconds and then display dashes (- -) in place of the pressure value.
For each subsequent ignition switch cycle, a chime will sound, the TPM Warning Light will flash on and off for 75 seconds and then remain on solid, and the instrument cluster will display a "SERVICE TPM SYSTEM" message for a minimum of five seconds and then display dashes (- -) in place of the pres- sure value.
Once you repair or replace the original road tire and reinstall it on the vehicle in place of the non matching full size spare or compact spare, the TPMS will update automatically. In addition, the TPM Warning Light will turn off and the graphic in the instrument cluster will display a new pressure value instead of dashes (- -), as long as no tire pressure is below the low-pressure warning limit in any of the four active road tires. The vehicle may need to be driven for up to 20 minutes above 15 mph (24 km/h) in order for the TPMS to receive this information.

The Trailer Tire Pressure Monitoring System (TTPMS) is a feature that displays the trailer tire pressure values and warn the driver of a low tire pressure event based on the drivers set target tire pressure value, through TTPMS settings found in the radio.

The TTPMS monitors the pressure of each tire and warns the driver through the instrument cluster, when either a low tire pressure condi- tion falls below 25% of the drivers set pressure or if a system malfunction occurs. The instru- ment cluster will display the actual tire pressure or dashes for each of the trailer tires in the correct trailer position, based on trailer configu- ration. The TTPMS system can support up to 12 trailer tires per configured trailer on up to four configurable trailers. Refer to “Uconnect Settings” in “Multimedia” for further informa- tion.

 

In order use this feature, the provided tire pres- sure sensors must be installed in the desired trailer tires and the sensors must be paired to the truck. If the target trailer requires more than the provided four sensors, additional sensors can be purchased at an authorized Ram dealer- ship.

With the sensors installed and the trailer near or connected to your Ram truck, initiate the pairing process by entering the settings menu in the radio and select trailer. Refer to “Uconnect Settings” in “Multimedia” for further informa- tion. Select the desired trailer profile to pair to, open the “Tire Pressure” menu, and hit “Setup All Tires.”

 

The vehicle may not be driven until the pairing process is complete.

 

Follow the on screen prompts to select the number of axles (1 - 3), the number of trailer tires (2, 4, 6, 8, or 12), and the set trailer tire pressure. The range is selectable anywhere between 25-125 PSI (172-862 kPa).

Once PSI (kPa) is programmed, the pairing screen appears. Tire sensors must be paired in order shown. Starting with Tire 1, deflate tire by 5 PSI (34 kPa) and wait for a horn chirp. It may take up to 3 minutes for the chirp to occur, indi- cating that the sensor has paired. Repeat process on each tire, in order, until complete. Do not exit the pairing screen until process is complete. If pairing was unsuccessful, a double horn chirp will sound, and a prompt on the touchscreen will allow you to retry the proce- dure; “Retry” will only appear when setup fails. Each tire must be successfully paired during a single pairing process to receive the success screen.

If the pairing process times out after three minutes of no communication with a sensor, a double horn chip will occur indicating the pairing has failed and a message will display on the radio indicating the process was unsuc- cessful. Under certain circumstances, the double horn chirp may continue to happen every three minutes indicating the failed pairing. If this happens, the horn chirping may be canceled by cycling the ignition button off and then back to run position.

When a tire pressure low in one or more of the active road tires is detected, the instrument cluster will display a message stating “Trailer Tire Pressure Low”. The instrument cluster will then display the TTPMS graphic showing the pressure values of each tire with the low tire pressure values in a different color.

Should this occur, you should stop as soon as possible and inflate the tires with a low pressure condition (those in a different color in the instru- ment cluster graphic) to the customer programmed target tire pressure value as shown at the top of the TTPMS instrument cluster graphic. Once the tire(s) are inflated, the system will automatically update the graphic display in the instrument cluster, returning to it’s original color. The vehicle may need to be driven for up to 10 minutes above 15 mph (24 km/h) in order for the TTPMS to receive the updated information.

If a system fault is detected, the instrument cluster will display a “Trailer Tire Pressure System Service Required” message for a minimum of five seconds.

Once the system fault is corrected the "Trailer Tire Pressure System Service Required" message will no longer be displayed. The vehicle may need to be driven for up to 10 minutes above 15 mph (24 km/h) in order for the TTPMS to receive the trailer tire pressure information.

A “Trailer Tire Pressure System Not Configured” message will be displayed in the Instrument Cluster on the TTPM instrument cluster graphic when a trailer number is selected that has not had trailer tire pressure sensors paired. To correct this condition, see “Trailer Tire Pressure Sensor Pairing” in “Multimedia”.

The “Trailer Sensors Detected Do Not Match Active Trailer” message will be displayed in the Instrument Cluster when the trailer sensors being received by the TTPM module do not match the trailer sensors paired to the current trailer number selected. This message will be displayed when the sensors being received completely match the sensors paired to another trailer number configured in the TTPM module.

To correct this condition, the correct trailer number must be selected in the radio. Refer to the “Uconnect Settings” in “Multimedia” for further information.

This feature notifies the user when the placard tire pressure is attained while inflating or deflating the tire.

The customer may choose to disable or enable the Tire Fill Alert feature through use of the customer settings in the radio.

Only one tire can be filled at a time when using the Tire Fill Alert system.
The Tire Fill Alert feature cannot be entered if an existing TPM system fault is set to “active” or if the system is in deactivation mode (if equipped).

The system will be activated when the system detects a increase of tire pressure, while filling the fire. The ignition must be in the RUN mode, with the transmission in PARK (P).

It is not required to have the engine running to enter Tire Fill Alert mode.

The hazard lamps will come on to confirm the vehicle is in Tire Fill Alert mode.

If the hazard lamps do not come on while inflating the tire, the TPM sensor may be in a inoperative position, preventing the TPM sensor signal from being received. In this case, the vehicle may need to be moved slightly forward or backward.

When Tire Fill Alert Mode is entered, the tire pressure display screen will be displayed in the instrument cluster.

The horn will chirp once to let the user know when to stop filling the tire, when it reaches recommended pressure.
The horn will chirp three times if the tire is over filled and will continue to chirp every five seconds if the user continues to inflate the tire.

 

The horn will chirp once again when enough air is let out to reach proper inflation level.
The horn will also chirp three times if the tire is then under-inflated and will continue to chirp every five seconds if the user continues to deflate the tire.

The Selectable Tire Fill Alert (STFA) system is an optional feature that is included as part of the normal Tire Fill Alert system. The system is designed to allow the customer to select a pres- sure to inflate or deflate the vehicle's front and rear axle tires to and to provide feedback to the customer while inflating or deflating the vehicle's tires.

In the Selectable Tire Fill Alert application, which is located in the apps menu of the U-connect System, the customer will be able to select a pressure setting for both the front and rear axle tire pressures by scrolling through a pressure range from XX to 15 psi in 1 psi incre- ments for each axle setting. XX = the vehicle’s cold placard pressure values for the front and rear axles as shown on the vehicle placard pres- sure label.

The customer may also store the pressure values chosen for each axle in the radio as a preset pressure. The customer will be allowed to store up to two sets of preset values in the radio for the front and rear axle pressure values.

Once the customer selects the tire pressures for the front and rear axles that they want to inflate or deflate to, they can begin inflating or deflating one tire at a time.

The STFA system will only support inflating or deflating one tire at a time.

The system will be activated when the TPM receiver module detects a change in tire pres- sure. The ignition must be in the RUN mode, with the transmission in PARK (P).

The hazard lamps will come on to confirm the vehicle is in Tire Fill Alert mode.

If the hazard lamps do not come on while inflating or deflating the tire, the TPM sensor may be in a inoperative position, preventing the TPM sensor signal from being received. In this case, the vehicle may need to be moved slightly forward or backward.

 

When Tire Fill Alert Mode is entered, the tire pressure display screen will be displayed in the instrument cluster.

The horn will chirp once when the selected pressure is reached to let the user know when to stop inflating or deflating the tire.
The horn will chirp three times if the tire is over inflated or over deflated and will continue to chirp every five seconds if the user continues to inflate or deflate the tire.
The horn will chirp once again when enough air is added or removed to reach proper selected pressure level.

Your vehicle may be equipped with a Tire Pres- sure Information System (TPIS).

The Tire Pressure Information System (TPIS) uses wireless technology with wheel rim mounted electronic sensors to transmit tire pressure levels. Sensors mounted to each wheel as part of the valve stem transmit tire pressure readings to the receiver module.

 

It is particularly important for you to check the tire pressure in all of the tires on your vehicle monthly and to maintain the proper pressure.

The TPIS consists of the following components:

Receiver module
Four TPM sensors (Single Rear Wheel (SRW) applications)
Six TPM sensors (Dual Rear Wheel (DRW) applications)
Pressure display in the instrument cluster

The TPIS system will display all four (Single Rear Wheel (SRW) applications) or six (Dual Rear Wheel (DRW) applications) tire pressure values in the instrument cluster display.

If a system fault is detected, the instrument cluster will display a "SERVICE TPM SYSTEM" message for a minimum of five seconds and then display dashes (- -) in place of the pressure value to indicate which sensor is not being received.

If the ignition switch is cycled, this sequence will repeat, providing the system fault still exists. If the system fault no longer exists, the "SERVICE TPM SYSTEM" message will no longer be displayed, and a pressure value will display in place of the dashes. A system fault can occur due to any of the following:

Signal interference due to electronic devices or driving next to facilities emitting the same radio frequencies as the TPM sensors.
Installing aftermarket window tinting that contains materials that may block radio wave signals.
Accumulation of snow or ice around the wheels or wheel housings.
Using tire chains on the vehicle.
Using wheels/tires not equipped with TPM sensors.
