2021 RAM 1500 Owners Manual - PARKSENSE FRONT/REAR PARK ASSIST SYSTEM — IF EQUIPPED

PARKSENSE FRONT/REAR PARK ASSIST SYSTEM — IF EQUIPPED

The ParkSense Park Assist system provides visual and audible indications of the distance between the rear and/or front fascia/bumper and a detected obstacle when backing up or moving forward (e.g. during a parking

maneuver). If your vehicle is equipped with the automatic braking function, the vehicle brakes may be automatically applied and released when the vehicle is in REVERSE if the system detects a possible collision with an obstacle.

The driver can disable the automatic braking function by turning ParkSense off via the ParkSense switch. The driver can also over- ride automatic braking by changing the gear or by pressing the gas pedal over 90% of its capacity during the braking event.

Automatic brakes will not be available if the vehicle is in 4WD Low.

Automatic brakes will not be available if ESC is not available.

Automatic brakes will not be available if there is a faulted condition detected with the Park- Sense Park Assist system or the Braking System.

The automatic braking function may only be applied if the vehicle deceleration is not enough to avoid colliding with a detected obstacle.

The automatic braking function may not be applied fast enough for obstacles that move toward the rear of the vehicle from the left and/or right sides.

The automatic braking function can be enabled/disabled from the Customer Programmable Features section of the Uconnect system.

ParkSense will retain its last known configu- 4

ration state for the automatic braking func-

tion through ignition cycles.

Trailer hitch ball assembly may cause false braking events if left attached after towing.

The automatic braking function is intended to assist the driver in avoiding possible collisions with detected obstacles when backing up in REVERSE gear.

The system is provided to assist the driver and not to substitute the driver.

The driver must stay in full control of the vehicle's acceleration and braking and is responsible for the vehicle's movements.

For limitations of this system and usage precautions, see page 194.

ParkSense will retain the last system state (enabled or disabled) from the last ignition cycle when the ignition is placed in the ON/RUN position.

ParkSense can be active only when the gear selector is in REVERSE or DRIVE. If ParkSense is enabled while in one of these gears, the system will remain active until the vehicle speed is increased to approximately 7 mph (11 km/h) or above. A warning will appear in the instrument cluster display indicating the vehicle is above ParkSense operating speed. The system will become active again if the vehicle speed is decreased to speeds less than approximately 6 mph (9 km/h).

PARKSENSE SENSORS

The four ParkSense sensors (six if equipped with Active Parksense), located in the front fascia/bumper, monitor the area in front of the vehicle that is within the sensors’ field of view, and the four ParkSense sensors, located in the rear fascia/bumper, monitor the area behind the vehicle that is within the sensors’ field of view. The front sensors can detect obstacles from approximately 12 inches (30 cm) up to 47 inches (120 cm) from the front fascia/ bumper. The rear sensors can detect obstacles from approximately 12 inches (30 cm) up to 79 inches (200 cm). These distances depend on the location, type and orientation of the obstacle in the horizontal direction.

PARKSENSE WARNING DISPLAY

The ParkSense Warning screen is located within the instrument cluster display page 114. It provides visual warnings to indicate the distance between the rear fascia/bumper and/ or front fascia/bumper and the detected obstacle.

PARKSENSE DISPLAY

The warning display will turn on indicating the system status when the vehicle is in REVERSE or when the vehicle is in DRIVE and an obstacle has been detected.

The system will indicate a detected obstacle by showing a single arc in the left, right, or center regions based on the obstacle’s distance and location relative to the vehicle.

If an obstacle is detected in the left, right, or center regions, the display will show a single arc in the left and/or right regions and the system will produce a tone. As the vehicle moves closer to the obstacle, the display will show the single arc moving closer to the vehicle and the tone will change from a single 1/2 second tone to slow, to fast, to continuous.

4

— No Tone/Solid Arc 6 — Fast Tone/Flashing Arc

— No Tone/Flashing Arc 7 — Fast Tone/Flashing Arc

— Fast Tone/Flashing Arc 8 — Slow Tone/Solid Arc

— Continuous Tone/Solid Arc 9 — Slow Tone/Solid Arc

— Continuous Tone/Solid Arc 10 — Single 1/2 Second Tone/Solid Arc

The vehicle is close to the obstacle when the display shows one flashing arc and sounds a continuous tone. The following chart shows the warning alert operation when the system is detecting an obstacle:

ParkSense will reduce the volume of the radio, if on, when the system is sounding an audio tone.

ParkSense will turn off the Front Park Assist audible alert (chime) after approximately three seconds when an obstacle has been detected, the vehicle is stationary, and brake pedal is applied.

The Front and Rear chime volume settings are programmable through the Uconnect system page 237.

ENABLING AND DISABLING FRONT AND/OR REAR PARKSENSE

Front ParkSense can be enabled and disabled with the Front ParkSense switch.

Rear ParkSense can be enabled and disabled with the Rear ParkSense switch.

When the Front or Rear ParkSense switch is pushed to disable the system, the instrument cluster display page 114 will show a vehicle

graphic of the Front or Rear ParkSense on/off state for two seconds.

When the gear selector is moved to REVERSE and the Front or Rear system is disabled, the instrument cluster display will show a vehicle graphic with “OFF” on the corresponding side. This vehicle graphic will be displayed for as long as the vehicle is in REVERSE.

Arc alerts from the enabled ParkSense system, will interrupt the five second messages, and the instrument cluster display will show the vehicle graphic with the corresponding arcs and “OFF” message.

The Front or Rear ParkSense switch LED will be on when Front or Rear ParkSense is disabled or requires service. The Front or Rear ParkSense switch LED will be off when the Front or Rear system is enabled. If the Front or Rear ParkSense switch is pushed, and the system requires service, the Front or Rear ParkSense switch LED will blink momentarily, and then the LED will be on.

SERVICE THE PARKSENSE PARK ASSIST SYSTEM

During vehicle start up, when the ParkSense System has detected a faulted condition, the instrument cluster will actuate a single chime, once per ignition cycle, and it will display the "PARKSENSE UNAVAILABLE WIPE REAR SENSORS", "PARKSENSE UNAVAILABLE WIPE FRONT SENSORS", or the "PARKSENSE UNAVAILABLE SERVICE REQUIRED" message

for five seconds. When the gear selector is moved to REVERSE and the system has detected a faulted condition, the instrument cluster display will display a "WIPE OFF" message on the corresponding blocked system while the vehicle is in REVERSE. The system will continue to provide arc alerts for the side that is functioning properly.

If "PARKSENSE UNAVAILABLE WIPE REAR SENSORS" or "PARKSENSE UNAVAILABLE WIPE

FRONT SENSORS" appears in the instrument cluster display make sure the outer surface and the underside of the rear fascia/bumper and/or front fascia/bumper is clean and clear of snow, ice, mud, dirt or other obstruction and then cycle the ignition. If the message continues to appear see an authorized dealer.

Water from a car wash or road slush in freezing weather may also cause sensors to become blocked.

If the "PARKSENSE UNAVAILABLE SERVICE

REQUIRED" message appears in the instrument cluster display, see your authorized dealer.

CLEANING THE PARKSENSE SYSTEM

Clean the ParkSense sensors with water, car wash soap and a soft cloth. Do not use rough or hard cloths. Do not scratch or poke the sensors.

PARKSENSE SYSTEM USAGE PRECAUTIONS

Ensure that the front and rear fascias/ bumpers are free of snow, ice, mud, dirt and debris to keep the ParkSense system oper- ating properly.

Jackhammers, large trucks, and other vibra- tions could affect the performance of Park- Sense.

When you turn Front or Rear ParkSense off, the instrument cluster display will show a vehicle graphic of the Front or Rear Park- Sense on/off state for two seconds. Further- more, once you turn Front or Rear ParkSense off, it remains off until you turn it on again, even if you cycle the ignition.

When you move the gear selector to the REVERSE position and Front or Rear Park- Sense is turned off, the instrument cluster display will show a vehicle graphic with "OFF" in the corresponding side. This vehicle graphic will be displayed for as long as the vehicle is in REVERSE.

ParkSense, when on, will reduce the volume of the radio when it is sounding a tone.

Clean the ParkSense sensors regularly, taking care not to scratch or damage them. The sensors must not be covered with ice, snow, slush, mud, dirt or debris. Failure to do so can result in the system not working prop- erly. The ParkSense system might not detect an obstacle behind or in front of the fascia/ bumper, or it could provide a false indication that an obstacle is behind or in front of the fascia/bumper.

Use the ParkSense switch to turn the Park- Sense system off if obstacles such as bicycle carriers, trailer hitches, etc. are placed near the rear fascia/bumper. Failure to do so can result in the system misinterpreting a close obstacle as a sensor problem, causing the “PARKSENSE UNAVAILABLE SERVICE REQUIRED” message to be appear in the instrument cluster display.

ParkSense should be disabled when the tail- gate is in the lowered or open position. A lowered tailgate could provide a false indica- tion that an obstacle is behind the vehicle and could also cause a false braking event.

The Rear ParkSense system will automati- cally disable when the system detects that a trailer with trailer brakes has been connected to the Integrated Trailer Brake Module.

The Front ParkSense system will automati- cally disable if a snow plow has been connected to the vehicle.
