Safety Features
The ABS provides increased vehicle stability and brake performance under most braking conditions. The system automatically prevents wheel lock and enhances vehicle control during braking.
The ABS performs a self-check cycle to ensure that the ABS is working properly each time the vehicle is started and driven. During this self-check, you may hear a slight clicking sound as well as some related motor noises.
The ABS is activated during braking when the system detects one or more wheels are beginning to lock. Road conditions such as ice, snow, gravel, bumps, railroad tracks, loose debris, or panic stops may increase the likelihood of ABS activation(s).
You also may experience the following normal characteristics when the ABS activates:
-
ABS motor noise or clicking sounds (you may continue to hear for a short time after the stop)
-
Brake pedal pulsations
-
A slight drop of the brake pedal at the end of the stop
The ABS is designed to function with the Original Equipment Manufacturer (OEM) tires. Modification may result in degraded ABS performance.
WARNING:
-
The ABS contains sophisticated electronic equipment that may be susceptible to interference caused by improperly installed or high output radio transmitting equipment. This interference can cause possible loss of anti-lock braking capability. Installation of such equipment should be performed by qualified professionals.
-
Pumping of the Anti-Lock Brakes will diminish their effectiveness and may lead to a collision. Pumping makes the stopping distance longer. Just press firmly on your brake pedal when you need to slow down or stop.
-
The ABS cannot prevent the natural laws of physics from acting on the vehicle, nor can it increase braking or steering efficiency beyond that afforded by the condition of the vehicle brakes and tires or the traction afforded.
-
The ABS cannot prevent collisions, including those resulting from excessive speed in turns, following another vehicle too closely, or hydroplaning.
-
The capabilities of an ABS equipped vehicle must never be exploited in a reckless or dangerous manner that could jeopardize the user’s safety or the safety of others.
ANTI-LOCK BRAKE SYSTEM (ABS) WARNING LIGHT
The yellow ABS Warning Light will turn on when the ignition is placed in the ON/RUN mode and may stay on for as long as four seconds.
If the ABS Warning Light remains on or comes on while driving, it indicates that the anti-lock portion of the brake system is not functioning and that service is required. However, the conventional brake system will continue to operate normally if the ABS Warning Light is on.
If the ABS Warning Light is on, the brake system should be serviced as soon as possible to restore the benefits of Anti-lock Brakes. If the ABS Warning Light does not come on when the ignition is placed in the ON/RUN mode, have the light repaired as soon as possible.
ELECTRONIC BRAKE CONTROL (EBC) SYSTEM
Your vehicle is equipped with an advanced Electronic Brake Control (EBC) system. This system includes Anti-Lock Brake System (ABS), Brake Assist System (BAS), Electronic Brake Force Distribution (EBD), Electronic Roll Mitigation (ERM), Electronic Stability Control (ESC), Hill Start Assist (HSA), and Traction Control System (TCS). These systems work together to enhance both vehicle stability and control in various driving conditions.
Your vehicle may also be equipped with Dynamic Steering Torque (DST), Hill Descent Control (HDC), Rain Brake Support (RBS), Ready Alert Braking (RAB), and Trailer Sway Control (TSC).
BRAKE ASSIST SYSTEM (BAS)
The BAS is designed to optimize the vehicle’s braking capability during emergency braking maneuvers. The system detects an emergency braking situation by sensing the rate and amount of brake application and then applies optimum pressure to the brakes. This can help reduce braking distances. The BAS complements the Anti-Lock Brake System (ABS). Applying the brakes very quickly results in the best BAS assistance. To receive the benefit of the system, you must apply continuous braking pressure during the stopping sequence (do not “pump” the brakes). Do not reduce brake pedal pressure unless braking is no longer desired. Once the brake pedal is released, the BAS is deactivated.
WARNING:
The Brake Assist System (BAS) cannot prevent the natural laws of physics from acting on the vehicle, nor can it increase the traction afforded by prevailing road conditions. BAS cannot prevent collisions, including those resulting from excessive speed in turns, driving on very slippery surfaces, or hydroplaning. The capabilities of a BAS-equipped vehicle must never be exploited in a reckless or dangerous manner, which could jeopardize the user's safety or the safety of others.
BRAKE SYSTEM WARNING LIGHT
The red Brake System Warning Light will turn on when the ignition is placed in the ON/RUN mode and may stay on for as long as four seconds.
If the Brake System Warning Light remains on or comes on while driving, it indicates that the brake system is not functioning properly and that immediate service is required. If the Brake System Warning Light does not come on when the ignition is placed in the ON/RUN mode, have the light repaired as soon as possible.
DYNAMIC STEERING TORQUE (DST)
DST is a feature of the Electronic Stability Control (ESC) and Electric Power Steering (EPS) modules that provides torque at the steering wheel for certain driving conditions in which the ESC module is detecting vehicle instability. The torque that the steering wheel receives is only meant to help the driver realize optimal steering behavior in order to reach/maintain vehicle stability. The only notification the driver receives that the feature is active is the torque applied to the steering wheel.
Note:
The DST feature is only meant to help the driver realize the correct course of action through small torques on the steering wheel, which means the effectiveness of the DST feature is highly dependent on the driver’s sensitivity and overall reaction to the applied torque. It is very important to realize that this feature will not steer the vehicle, meaning the driver is still responsible for steering the vehicle.
ELECTRONIC BRAKE FORCE DISTRIBUTION (EBD)
EBD manages the distribution of the braking torque between the front and rear axles by limiting braking pressure to the rear axle. This is done to prevent overslip of the rear wheels to avoid vehicle instability, and to prevent the rear axle from entering ABS before the front axle.
ELECTRONIC ROLL MITIGATION (ERM)
ERM anticipates the potential for wheel lift by monitoring the driver’s steering wheel input and the speed of the vehicle. When ERM determines that the rate of change of the steering wheel angle and vehicle’s speed are sufficient to potentially cause wheel lift, it then applies the appropriate brake and may also reduce engine power to lessen the chance that wheel lift will occur. ERM can only reduce the chance of wheel lift occurring during severe or evasive driving maneuvers; it cannot prevent wheel lift due to other factors, such as road conditions, leaving the roadway, or striking objects or other vehicles.
WARNING:
Many factors, such as vehicle loading, road conditions and driving conditions, influence the chance that wheel lift or rollover may occur. ERM cannot prevent all wheel lift or rollovers, especially those that involve leaving the roadway or striking objects or other vehicles. The capabilities of an ERM-equipped vehicle must never be exploited in a reckless or dangerous manner which could jeopardize the user's safety or the safety of others.
ELECTRONIC STABILITY CONTROL (ESC)
ESC enhances directional control and stability of the vehicle under various driving conditions. ESC corrects for oversteering or understeering of the vehicle by applying the brake of the appropriate wheel(s) to counteract the above conditions. Engine power may also be reduced to help the vehicle maintain the desired path.
-
Oversteer — when the vehicle is turning more than appropriate for the steering wheel position.
-
Understeer — when the vehicle is turning less than appropriate for the steering wheel position.
ESC uses sensors in the vehicle to determine the vehicle path intended by the driver and compares it to the actual path of the vehicle. When the actual path does not match the intended path, ESC applies the brake of the appropriate wheel to assist in counteracting the oversteer or understeer condition.
The ESC Activation/Malfunction Indicator Light located in the instrument cluster will start to flash as soon as the ESC system becomes active. The ESC Activation/Malfunction Indicator Light also flashes when the TCS is active. If the ESC Activation/Malfunction Indicator Light begins to flash during acceleration, ease up on the accelerator and apply as little throttle as possible. Be sure to adapt your speed and driving to the prevailing road conditions.
WARNING:
-
Electronic Stability Control (ESC) cannot prevent the natural laws of physics from acting on the vehicle, nor can it increase the traction afforded by prevailing road conditions. ESC cannot prevent accidents, including those resulting from excessive speed in turns, driving on very slippery surfaces, or hydroplaning. ESC also cannot prevent accidents resulting from loss of vehicle control due to inappropriate driver input for the conditions. Only a safe, attentive, and skillful driver can prevent accidents. The capabilities of an ESC equipped vehicle must never be exploited in a reckless or dangerous manner which could jeopardize the user’s safety or the safety of others.
-
Vehicle modifications, or failure to properly maintain your vehicle, may change the handling characteristics of your vehicle, and may negatively affect the performance of the ESC system. Changes to the steering system, suspension, braking system, tire type and size or wheel size may adversely affect ESC performance. Improperly inflated and unevenly worn tires may also degrade ESC performance. Any vehicle modification or poor vehicle maintenance that reduces the effectiveness of the ESC system can increase the risk of loss of vehicle control, vehicle rollover, personal injury and death.
ESC OPERATING MODES
Depending upon model and mode of operation, the ESC system may have multiple operating modes.
ESC On
This is the normal operating mode for the ESC. Whenever the vehicle is started, the ESC system will be in this mode. This mode should be used for most driving conditions. Alternate ESC modes should only be used for specific reasons as noted in the following paragraphs.
Partial Off
This mode may be useful if the vehicle becomes stuck. This mode may modify TCS and ESC thresholds for activation, which allows for more wheel spin than normally allowed.
To enter the “Partial Off” mode, momentarily push the ESC OFF button, located below the radio. The ESC OFF Indicator Light will illuminate. To turn the ESC on again, momentarily push the ESC OFF button and the ESC OFF Indicator Light will turn off.
Note:
When driving with snow chains, or when starting off in deep snow, sand, or gravel, it may be desirable to allow more wheel spin. This can be accomplished by momentarily pushing the ESC OFF button to enter “Partial Off” mode. Once the situation requiring “Partial Off” mode is overcome, turn ESC back on by momentarily pushing the ESC OFF button. This may be done while the vehicle is in motion.
WARNING:
-
When in “Partial Off” mode, the TCS functionality of ESC, except for the limited slip feature described in the TCS section, has been disabled and the ESC OFF Indicator Light will be illuminated. When in “Partial Off” mode, the engine power reduction feature of TCS is disabled, and the enhanced vehicle stability offered by the ESC system is reduced.
-
Trailer Sway Control (TSC) is disabled when the ESC system is in the “Partial Off” mode.
Full Off (Four-Wheel Drive Models Only)
This mode is intended for off-highway or off-road use when ESC stability features could inhibit vehicle maneuverability due to trail conditions. This mode is entered by pushing and holding the ESC OFF button for five seconds when the vehicle is stopped and the engine is running. After five seconds, the ESC OFF Indicator Light will illuminate and the “ESC OFF” message will appear in the instrument cluster display.
In this mode, ESC and TCS, except for the “limited slip” feature described in the TCS section, are turned off until the vehicle reaches a speed of 40 mph (64 km/h). At 40 mph (64 km/h), the system returns to “Partial Off” mode, as described above. TCS remains off. When the vehicle speed drops below 30 mph (48 km/h), the ESC system shuts off. ESC is deactivated at low vehicle speeds so that it will not interfere with off-road driving. However, ESC function returns to provide the stability feature at speeds above 40 mph (64 km/h). The ESC OFF Indicator Light will always be illuminated when ESC is off.
To turn ESC on again, momentarily push the ESC OFF button. This will restore the “ESC On” mode of operation.
Note:
The “ESC OFF” message will display and an audible chime will sound when the gear selector is placed into the PARK position from any other position, and then moved out of the PARK position. This will occur even if the message was previously cleared.
WARNING:
In the "Full Off" mode, the engine torque reduction and stability features are disabled. In an emergency evasive maneuver, the ESC system will not engage to assist in maintaining stability. “Full Off” mode is intended for off-highway or off-road use only.
ESC ACTIVATION/MALFUNCTION INDICATOR LIGHT AND ESC OFF INDICATOR LIGHT
The ESC Activation/Malfunction Indicator Light in the instrument cluster will come on when the ignition is placed in the ON mode. It should go out with the engine running. If the ESC Activation/Malfunction Indicator Light comes on continuously with the engine running, a malfunction has been detected in the ESC system. If this light remains on after several ignition cycles, and the vehicle has been driven several miles (km) at speeds greater than 30 mph (48 km/h), see an authorized dealer as soon as possible to have the problem diagnosed and corrected.
The ESC Activation/Malfunction Indicator Light starts to flash as soon as the tires lose traction and the ESC system becomes active. The ESC Activation/Malfunction Indicator Light also flashes when Traction Control System (TCS) is active. If the ESC Activation/Malfunction Indicator Light begins to flash during acceleration, ease up on the accelerator and apply as little throttle as possible. Be sure to adapt your speed and driving to the prevailing road conditions.
The ESC OFF Indicator Light indicates the customer has elected to have the Electronic Stability Control (ESC) in a reduced mode.
Note:
-
The ESC Activation/Malfunction Indicator Light and the ESC OFF Indicator Light come on momentarily each time the ignition is placed in the ON/RUN position.
-
Each time the ignition is placed in the ON/RUN position, the ESC system will be on even if it was turned off previously.
-
The ESC system will make buzzing or clicking sounds when it is active. This is normal; the sounds will stop when ESC becomes inactive following the maneuver that caused the ESC activation.
EMERGENCY STOP SIGNAL (ESS) — IF EQUIPPED
The ESS activates the hazard lights at a faster than normal speed when heavy brake pressure is applied. ESS will only activate when the speed is above 31 mph (50 km/h). The ESS operates independently of other lamps, and will turn on and off automatically. This indicates to others that the vehicle is stopping quickly.
Note:
-
A warning light will illuminate within the instrument cluster to inform the driver that the ESS feature has been activated.
-
When towing a trailer, ESS will also activate the rear indicator lights of the trailer.
HILL DESCENT CONTROL (HDC) — IF EQUIPPED
Hill Descent Control (HDC) is intended for low speed off-road driving while in 4WD Low. HDC maintains vehicle speed while descending hills during various driving situations. HDC controls vehicle speed by actively controlling the brakes.
HDC has three states:
-
Off (feature is not enabled and will not activate).
-
Enabled (feature is enabled and ready but activation conditions are not met, or driver is actively overriding with brake or throttle application).
-
Active (feature is enabled and actively controlling vehicle speed).
Enabling HDC
HDC is enabled by pushing the HDC switch, located in front of the gear selector. The following conditions must also be met to enable HDC:
-
The driveline is in 4WD Low.
-
The vehicle speed is below 20 mph (32 km/h).
-
The Electric Park Brake (EPB) is released.
-
The driver’s door is closed.
Activating HDC
Once HDC is enabled, it will activate automatically if driven down a grade of sufficient magnitude (greater than approximately 8%). The set speed for HDC is selectable by the driver and can be adjusted within the thresholds by using throttle or brake application.
Driver Override:
The driver may override HDC activation speed with throttle or brake application at any time.
Deactivating HDC
HDC will be deactivated but remain available if any of the following conditions occur:
-
Driver overrides HDC set speed with a speed exceeding 20 mph (32 km/h) but remains below 25 mph (40 km/h).
-
Vehicle is on a downhill grade of insufficient magnitude (less than approximately 8%), is on level ground, or is on an uphill grade.
-
Vehicle is shifted to PARK.
Disabling HDC
HDC will be deactivated and disabled if any of the following conditions occur:
-
The driver pushes the HDC switch.
-
The driveline is shifted out of 4WD Low.
-
The driver’s door opens.
-
The vehicle is driven greater than 25 mph (40 km/h) (HDC exits immediately.)
Feedback To The Driver:
The instrument cluster has an HDC icon and the HDC switch has an LED, which offers feedback to the driver about the state HDC is in.
-
The cluster icon and switch lamp will illuminate and remain solid when HDC is enabled or activated. This is the normal operating condition for HDC.
-
The switch lamp will flash for several seconds then extinguish when the driver pushes the HDC switch when enable conditions have not been met.
The HDC switch is located within the Selec-Terrain knob in the upper right position.
WARNING:
HDC is only intended to assist the driver in controlling vehicle speed when descending hills. The driver must remain attentive to the driving conditions and is responsible for maintaining a safe vehicle speed.
HILL START ASSIST (HSA)
HSA is designed to mitigate roll back from a complete stop while on an incline. If the driver releases the brake while stopped on an incline, HSA will continue to hold the brake pressure for a short period. If the driver does not apply the throttle before this time expires, the system will release brake pressure and the vehicle will roll down the hill as normal.
The following conditions must be met in order for HSA to activate:
-
The feature must be enabled.
-
The vehicle must be stopped.
-
The parking brake must be off.
-
The driver’s door must be closed.
-
The vehicle must be on a sufficient grade.
-
The gear selection must match vehicle uphill direction (i.e., vehicle facing uphill is in forward gear; vehicle backing uphill is in REVERSE gear).
-
HSA will work in REVERSE gear and all forward gears. The system will not activate if the transmission is in PARK or NEUTRAL.
WARNING:
There may be situations where the Hill Start Assist (HSA) will not activate and slight rolling may occur, such as on minor hills or with a loaded vehicle, or while pulling a trailer. HSA is not a substitute for active driving involvement. It is always the driver’s responsibility to be attentive to distance to other vehicles, people, and objects, and most importantly brake operation to ensure safe operation of the vehicle under all road conditions. Your complete attention is always required while driving to maintain safe control of your vehicle. Failure to follow these warnings can result in a collision or serious personal injury.
DISABLING AND ENABLING HSA
This feature can be turned on or turned off. To change the current setting, proceed as follows:
If disabling HSA using Uconnect settings see "⇨INSTRUMENT CLUSTER DISPLAY".
TOWING WITH HSA
Hill Start Assist (HSA) will also provide assistance to mitigate roll back while towing a trailer.
WARNING:
-
If you use a trailer brake controller with your trailer, the trailer brakes may be activated and deactivated with the brake switch. If so, there may not be enough brake pressure to hold both the vehicle and the trailer on a hill when the brake pedal is released. In order to avoid rolling down an incline while resuming acceleration, manually activate the trailer brake or apply more vehicle brake pressure prior to releasing the brake pedal.
-
HSA is not a parking brake. Always apply the parking brake fully when exiting your vehicle. Also, be certain to place the transmission in PARK.
-
Failure to follow these warnings can result in a collision or serious personal injury.
RAIN BRAKE SUPPORT (RBS)
RBS may improve braking performance in wet conditions. It will periodically apply a small amount of brake pressure to remove any water buildup on the front brake rotors. It functions when the windshield wipers are in LO or HI speed. When Rain Brake Support is active, there is no notification to the driver and no driver interaction is required.
READY ALERT BRAKING (RAB)
RAB may reduce the time required to reach full braking during emergency braking situations. It anticipates when an emergency braking situation may occur by monitoring how fast the throttle is released by the driver. The Electronic Brake Controller (EBC) system will prepare the brake system for a panic stop.
TRACTION CONTROL SYSTEM (TCS)
The TCS monitors the amount of wheel spin for each of the driven wheels. If wheel spin is detected, the TCS may apply brake pressure to the spinning wheel(s) and/or reduce vehicle power to provide enhanced acceleration and stability. A feature of the TCS, Brake Limited Differential (BLD) functions similarly to a limited slip differential and controls the wheel spin across a driven axle. If one wheel on a driven axle is spinning faster than the other, the system will apply the brake of the spinning wheel. This will allow more vehicle torque to be applied to the wheel that is not spinning. BLD may remain enabled even if TCS and ESC are in reduced modes.
TRAILER SWAY CONTROL (TSC)
TSC uses sensors in the vehicle to recognize an excessively swaying trailer and will take the appropriate actions to attempt to stop the sway. TSC will become active automatically once an excessively swaying trailer is recognized.
Note:
TSC cannot stop all trailers from swaying. Always use caution when towing a trailer and follow the trailer tongue weight recommendations "⇨TRAILER TOWING".
When TSC is functioning, the ESC Activation/Malfunction Indicator Light will flash, the engine power may be reduced and you may feel the brakes being applied to individual wheels to attempt to stop the trailer from swaying. TSC is disabled when the ESC system is in the “Partial Off” or “Full Off” modes.
WARNING:
If TSC activates while driving, slow the vehicle down, stop at the nearest safe location, and adjust the trailer load to eliminate trailer sway.
