WHAT IS REVERSE BRAKE
ASSIST
Reverse brake assist is designed to reduceimpact damage or assist in avoiding acollision while in reverse (R). Using sensorson the rear of the vehicle, it can detect apossible collision and apply the brakes. Iffull braking occurs, the system attemptsto stop the vehicle a safe distance fromthe obstacle.
HOW DOES REVERSE BRAKE
ASSIST WORK
Reverse brake assist functions when inreverse (R) and traveling at a speed of1–7 mph (2–12 km/h).
If the system detects an obstacle behindyour vehicle, it provides a warning throughthe rear parking aid or cross traffic alertsystem.
REVERSE BRAKE ASSIST
PRECAUTIONS
WARNING: You are responsible forcontrolling your vehicle at all times. Thesystem is designed to be an aid and doesnot relieve you of your responsibility todrive with due care and attention. Failureto follow this instruction could result inthe loss of control of your vehicle,personal injury or death.
WARNING: To help avoid personalinjury, always use caution when inreverse (R) and when using the sensingsystem.
WARNING: The system may notoperate properly during severe weatherconditions, for example snow, ice, heavyrain and spray. Always drive with duecare and attention. Failure to take caremay result in a crash.
WARNING: Traffic control systems,fluorescent lamps, inclement weather,air brakes, external motors and fans mayaffect the correct operation of thesensing system. This may cause reducedperformance or false alerts.
WARNING: Some situations andobjects prevent hazard detection. Forexample low or direct sunlight, inclementweather, unconventional vehicle types,and pedestrians. Apply the brakes whennecessary. Failure to follow thisinstruction could result in the loss ofcontrol of your vehicle, personal injury ordeath.
WARNING: Do not use the systemwith accessories that extend beyond thefront or rear of your vehicle, for examplea trailer hitch or bike rack. The system isnot able to make corrections for theadditional length of the accessories.

HOW DOES STABILITY
CONTROL WORK
WARNING: Vehicle modificationsinvolving braking system, aftermarketroof racks, suspension, steering system,tire construction and wheel and tire sizemay change the handling characteristicsof your vehicle and may adversely affectthe performance of the electronicstability control system. In addition,installing any stereo speakers mayinterfere with and adversely affect theelectronic stability control system.Reducing the effectiveness of theelectronic stability control system couldlead to an increased risk of loss of vehiclecontrol, vehicle rollover, personal injuryand death.
WARNING: Remember that evenadvanced technology cannot defy thelaws of physics. It's always possible tolose control of a vehicle due toinappropriate driver input for theconditions. Aggressive driving on anyroad condition can cause you to losecontrol of your vehicle increasing the riskof personal injury or property damage.Activation of the electronic stabilitycontrol system is an indication that atleast some of the tires have exceededtheir ability to grip the road; this couldreduce the operator's ability to controlthe vehicle potentially resulting in a lossof vehicle control, vehicle rollover,personal injury and death.
If a driving condition activates either thestability control or traction control you mayexperience the following conditions:
•The stability and traction control lightflashes.
•Your vehicle slows down.
•Reduced engine power.
The stability control system has severalfeatures built into it to help you maintaincontrol of your vehicle:
Electronic Stability Control
Electronic stability control enhances yourvehicle’s ability to prevent skids or lateralslides by applying brakes to one or moreof the wheels individually and, if necessary,reducing engine power.
Roll Stability Control
Roll stability control enhances yourvehicle’s ability to prevent rollovers bydetecting your vehicle’s roll motion andthe rate at which it changes by applyingthe brakes to one or more wheelsindividually.
Curve Control
Curve control enhances your vehicle’sability to follow the road when corneringseverely or avoiding objects in the roadway.Curve control operates by reducing enginepower and, if necessary, applying brakesto one or more of the wheels individually.
Side Wind Stabilization
Side wind stabilization is an advancedfeature that works by carefully applyingthe brakes on one side of the vehicle toreduce the effect of a side wind gust onthe vehicle's path.
Traction Control
Traction control enhances your vehicle’sability to maintain traction of the wheelsby detecting and controlling wheel spin.See What Is Traction Control (page 268).
