SAFETY FEATURES
Anti-Lock Brake System (ABS)
The Anti-Lock Brake System (ABS) provides increased vehicle stability and brake performance under most brak- ing 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.
ABS is activated during braking when the system detects one or more wheels begin 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 when ABS activates:
The ABS motor noise (it may continue to run for a short time after the stop).
These are all normal characteristics of ABS.
WARNING!
The ABS contains sophisticated electronic equip- ment that may be susceptible to interference caused by improperly installed or high output radio trans- mitting equipment. This interference can cause pos- sible 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 brak- ing 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.

Your vehicle is equipped with an advanced Electronic Brake Control system (EBC). This system includes Elec- tronic Brake Force Distribution (EBD), Anti-Lock Brake System (ABS), Brake Assist System (BAS), Hill Start Assist (HSA), Traction Control System (TCS), Electronic Stability Control (ESC), and Electronic Roll Mitigation (ERM). These
tion may result in degraded ABS performance. systems work together to enhance both vehicle stability 5
Anti-Lock Brake Warning Light
The yellow “Anti-Lock Brake Warning Light” will turn on when the ignition is turned to the ON/RUN mode and may stay on for as long as four seconds.
If the “Anti-Lock Brake 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 sys- tem will continue to operate normally if the “Anti-Lock Brake Warning Light” is on.
If the “Anti-Lock Brake Warning Light” is on, the brake system should be serviced as soon as possible to restore the benefits of anti-lock brakes. If the “Anti-Lock Brake Warning Light” does not come on when the ignition is turned to the ON/RUN mode, have the light repaired as soon as possible.
and control in various driving conditions.
Your vehicle may also be equipped with Ready Alert Braking (RAB), and Rain Brake Support (RBS).
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s braking capability during emergency braking maneuvers. The sys- tem 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.
Brake System Warning Light
The red “Brake System Warning Light” will turn on when the ignition is turned to 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 re- quired. If the “Brake System Warning Light” does not come on when the ignition is turned to the ON/RUN mode, have the light repaired as soon as possible.
Electronic Brake Force Distribution (EBD)
This function 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)
This system 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.
NOTE: ERM is disabled anytime the ESC is in “Full Off” mode (if equipped). Refer to “Electronic Stability Control (ESC)” in this section for a complete explanation of the available ESC modes.
Electronic Stability Control (ESC)
This system enhances directional control and stability of the vehicle under various driving conditions. ESC corrects for oversteering or understeering of the vehicle by apply- ing the brake of the appropriate wheel(s) to assist in counteracting the oversteer or understeer condition. Engine power may also be reduced to help the vehicle maintain the desired path.
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.
Oversteer — when the vehicle is turning more than appropriate for the steering wheel position. 5
Understeer — when the vehicle is turning less than appropriate for the steering wheel position.
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.
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 ve- hicle 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 reck- less or dangerous manner which could jeopardize the user’s safety or the safety of others.
Vehicle modifications, or failure to properly main-
tain your vehicle, may change the handling charac- teristics 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

ESC Operating Modes
NOTE: 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
The “Partial Off” mode is intended for times when a more spirited driving experience is desired. This mode may modify TCS and ESC thresholds for activation, which allows for more wheel spin than normally allowed. This mode may be useful if the vehicle becomes stuck.
To enter the “Partial Off” mode, momentarily push the “ESC Off” switch and the “ESC Off Indicator Light” will illuminate. To turn the ESC on again, momentarily push the “ESC Off” switch and the “ESC Off Indicator Light” will turn off.
Full Off – If Equipped
This mode is intended for off-highway or off-road use only and should not be used on any public roadways. In this mode, TCS and ESC features are turned OFF. To enter the “Full Off” mode, push and hold the “ESC Off” switch for five seconds while the vehicle is stopped with the engine running. After five seconds, a chime will sound, the “ESC
Off Indicator Light” will illuminate, and the “ESC OFF” 5
message will display in the instrument cluster. To turn ESC ON again, momentarily push the “ESC Off” switch.
NOTE:
For vehicles with multiple partial ESC modes a momen- tary button push will toggle the ESC mode. Multiple momentary button pushed may be required to return to ESC On.
Trailer Sway control (TSC) is disabled when the ESC system is in the “Partial Off” mode.
If Equipped — "ESC Sport" and "ESC Track" are ESC partial off mode(s).

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 turned to 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 (kilometers) 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” (lo- cated in the instrument cluster) 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 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.
NOTE:
The “ESC Activation/Malfunction Indicator Light” and the “ESC OFF Indicator Light” come on momentarily each time the ignition is turned ON.
Each time the ignition is turned ON, 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.
The “ESC OFF Indicator Light” indicates the customer has elected to have the Electronic Sta- bility Control (ESC) in a reduced mode.
Hill Start Assist (HSA)
The HSA system 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 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. For vehicles equipped with a manual transmission, if the clutch is pressed, HSA will remain active.
Towing With HSA
HSA will also provide assistance to mitigate roll back while towing a trailer.

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 your instrument cluster display, refer to “Instrument Cluster Display” in “Getting To Know Your Instrument Panel” for further information.
If disabling HSA using Uconnect Settings, refer to “Uconnect Settings” in “Multimedia” for further infor- mation.
For vehicles not equipped with an instrument cluster display, perform the following steps:
Rain Brake Support (RBS)
Rain Brake Support 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 interac-
system will apply the brake of the spinning wheel. This will allow more engine power to be applied to the wheel that is not spinning. BLD may remain enabled even if TCS and ESC are in a reduced mode.
