WHAT IS REVERSE BRAKING
ASSIST
Reverse braking assist is designed toreduce impact damage or assist in avoidinga collision while in reverse (R). Usingsensors on the rear of the vehicle, it candetect a possible collision and apply thebrakes. If full braking occurs, the systemattempts to stop the vehicle a safedistance from the obstacle.
HOW DOES REVERSE
BRAKING ASSIST WORK
Reverse braking 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.

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.
The system only applies the brakes for ashort period of time when an event occurs.Act as soon as you notice the brakes applyto remain in control of the vehicle. If youdo not intervene the vehicle may start tomove again.
Note:Certain add-on devices around thebumper or fascia may create false alerts.For example, large trailer hitches, bicycle orsurfboard racks, license plate brackets,bumper covers or any other device that mayblock the normal detection zone of thesystem. Remove the add-on device toprevent false alerts.

Note:The system does not react to smallor moving objects, particularly those closeto the ground.
Note:The system does not operate duringhard acceleration or steering.
Note:If your vehicle sustains damage tothe bumper or fascia leaving it misalignedor bent, it could alter the sensing zonecausing inaccurate measurement ofobstacles or false alerts.
Note:Vehicle loading and suspensionchanges can impact the angle of the sensorsand may change the normal detection zoneof the system resulting in inaccuratemeasurement of obstacles or false alerts.
Note:When you connect a trailer, thesystem may detect the trailer and providean alert, or the system turns off. If thesystem does not turn off, manually switchthe system off after you connect the trailer.
Note:You may experience reduced systemperformance on road surfaces that limitdeceleration. For example, roads with ice,loose gravel, mud or sand.

PARKING AID PRECAUTIONS
WARNING: To help avoid personalinjury, always use caution when inreverse (R) and when using the sensingsystem.
WARNING: The system may notdetect objects with surfaces that absorbreflection. Always drive with due careand attention. Failure to take care mayresult 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: The system may notdetect small or moving objects,particularly those close to the ground.
WARNING: The parking aid systemcan only assist you to detect objectswhen your vehicle is moving at parkingspeeds. To help avoid personal injury youmust take care when using the parkingaid system.
WARNING: The system may notfunction if the sensor is blocked.
WARNING: In cold and severeweather conditions the system may notfunction. Rain, snow and spray can alllimit sensor performance.
WARNING: If damage occurs in theimmediate area surrounding the sensor,have your vehicle checked as soon aspossible.
Note:If your vehicle sustains damageleaving the sensors misaligned, this willcause inaccurate measurements or falsealerts.
When you connect a trailer to your vehicle,the rear parking aid detects the trailer andprovides an alert. Disable the parking aidwhen you connect a trailer to prevent thealert.
Note:Connected trailers might be detectedby the vehicle and parking aid turns offautomatically in those instances.
Note:Certain add-on devices installedaround the bumper or fascia may createfalse alerts, for example, large trailerhitches, bike or surfboard racks, license platebrackets, bumper covers or any other devicethat could block the normal detection zoneof the parking aid system. Aftermarket sparetires or spare tire covers mounted to the reartailgate could cause false alerts from thepark aid system. Remove the add-on deviceto prevent false alerts.
Note: Keep the sensors free from snow, iceand large accumulations of dirt. If thesensors are covered, the system's accuracycan be affected.
Do not clean the sensors with sharpobjects.
Note: When using a programmed MyKey,you cannot switch the parking aids off. SeeMyKey™ (page 75).

WARNING: On rare occasions,detection issues can occur due to theroad infrastructures, for example bridges,tunnels and safety barriers. In thesecases, the system may brake late orunexpectedly. At all times, you areresponsible for controlling your vehicle,supervising the system and intervening,if required.
WARNING: If the systemmalfunctions, have your vehicle checkedas soon as possible.
WARNING: Large contrasts inoutside lighting can limit sensorperformance.
WARNING: The system only warnsof vehicles detected by the radar sensor.In some cases there may be no warningor a delayed warning. Apply the brakeswhen necessary. Failure to follow thisinstruction could result in personal injuryor death.
WARNING: The system may notdetect stationary or slow movingvehicles below 6 mph (10 km/h).
WARNING: The system does notdetect pedestrians or objects in the road.
WARNING: The system does notdetect oncoming vehicles in the samelane.
WARNING: The system may notoperate properly if the sensor is blocked.Keep the windshield free fromobstruction.
