REVERSE BRAKING ASSIST –FREQUENTLY ASKED QUESTIONS
Why is reverse braking assist unavailable?
•Make sure the reverse braking assist ison. See Switching Reverse BrakingAssist On and Off (page 239).
•Make sure that all doors, liftgate ortailgate and hood are closed. Drive thevehicle on a straight road for a shortperiod. If the message remains, have thesystem checked.
•If your vehicle has the cross traffic alertsystem, make sure it is on. See SwitchingCross Traffic Alert On and Off (page 318).
•Make sure the rear parking aid system ison. See Parking Aids (page 255).
•Make sure the traction control is on. SeeSwitching Traction Control On and Off(page 245).
Note:The traction control automatically turnsoff if four-wheel drive low and certain drivemodes such as mud/ruts and snow/sand isactivated.
•Your vehicle may have sustained a rearend impact. Have the sensors checkedfor proper coverage and operation.
•An anti-lock brake, traction control orstability control event may have occurred.Reverse braking assist resumesoperation when the event is complete.
•Make sure the rear view camera and 360degree camera are not dirty orobstructed. If dirty, clean the camera. Ifthe message still appears after cleaningthe camera, wait a short time for themessage to clear. If the message doesnot clear, have the system checked.
•Make sure the cross traffic alert, rearparking aid and side parking aid sensorsare not blocked or faulty. See Locatingthe Cross Traffic Alert Sensors (page318). See Locating the Rear Parking AidSensors (page 256). See Locating theSide Parking Aid Sensors (page 259).
•You recently had your vehicle serviced,or the battery disconnected. Drive yourvehicle a short distance to resumesystem operation.
•Reverse braking assist does not functionwhen you connect a trailer. Operationresumes when you disconnect the trailer.
Note:If the answers to why the system isunavailable do not assist in returning reversebraking assist to available, have the systemchecked as soon as possible.

WHAT IS DRIVE MODE CONTROL
Your vehicle has various drive modes thatyou can select for different drivingconditions. Depending on the drive modethat you select, the system adjusts variousvehicle settings.
HOW DOES DRIVE MODE
CONTROL WORK
Drive mode control adjusts your vehicleconfiguration for each mode you select.
Changing the drive mode adjusts thesteering effort and feel of the steeringsystem.
The stability and traction control assist yourvehicle control in adverse conditions orhigh-performance driving.
Throttle control enhances the powertrainresponse, transmission controls becomeoptimized with shift schedules, andfour-wheel drive settings are optimized andtuned to each mode.
Changing the drive mode can engage ordisengage the electronic locking differentials.
Changing the drive mode changes thefour-wheel drive mode to the default settingfor the selected drive mode.
Note:The system has diagnostic checks thatcontinuously monitor the system for properoperation. If a mode is unavailable due to asystem fault, the drive mode system defaultsto normal. When the system defaults tonormal, the driveline settings remain thesame as prior to the system fault.
Note:The system reverts to the normalmode each time you start your vehicle. Atstartup the system also displays a prompton the instrument cluster display that givesyou the option to return to the previouslyselected drive mode during the last ignitioncycle. If you select yes, the system returnsto the last selected drive mode and thedefault driveline settings associated withthat mode. If you select no, the systemremains in normal mode and the drivelinesettings remain the same as selected in theprior ignition cycle. If you do not select yesor no, the system stays in normal mode andthe driveline settings remain the same asselected in the prior ignition cycle.

WARNING: The system does notdetect vehicles moving in a differentdirection or animals. Apply the brakeswhen necessary. Failure to follow thisinstruction could result in the loss ofcontrol of your vehicle, personal injury ordeath.
WARNING: The system does notoperate during hard acceleration orsteering. Failure to take care may lead toa crash or personal injury.
WARNING: The system may operatewith reduced function during cold andinclement weather conditions. Snow, ice,rain, spray and fog can adversely affect thesystem. Keep the front camera and radarfree of snow and ice. Failure to follow thisinstruction may result in the loss of controlof your vehicle, serious personal injury ordeath.
WARNING: Take additional care ifyour vehicle is heavily loaded or you aretowing a trailer. These conditions couldresult in reduced performance of thissystem. Failure to follow this instructioncould result in the loss of control of yourvehicle, personal injury or death.
WARNING: The system cannot helpprevent all crashes. Do not rely on thissystem to replace driver judgment and theneed to maintain a safe distance andspeed.
WARNING: System performancecould be reduced in situations where thevehicle camera has limited detectioncapability. These situations include but arenot limited to direct or low sunlight,vehicles at night without tail lights,unconventional vehicle types, pedestriansor cyclists with complex backgrounds,
running pedestrians or fast moving cyclists,partly obscured pedestrians or cyclists,pedestrians or cyclists that the systemcannot distinguish from a group. Failure totake care may result in the loss of controlof your vehicle, personal injury or death.
PRE-COLLISION ASSIST
LIMITATIONS
Pre-collision assist depends on the detectionability of its camera and sensors. Anyobstructions or damage to these areas canlimit detection or prevent the system fromfunctioning. See Locating the Pre-CollisionAssist Sensors (page 324).
The system is active at 3 mph (5 km/h) andabove.
Note:The pre-collision assist systemautomatically disables when you selectfour-wheel drive low or manually disableAdvanceTrac™.

What does it mean if the trailer is at itsmaximum angle or the system deactivatedby trailer angle?
You are at the maximum controllabletrailer angle for the system. Place yourvehicle in drive (D) and pull forward toget the truck and trailer back to anin-line position. If this messageconsistently displays, this could indicatethe sticker is incorrectly applied, thetrailer needs to be recalibrated or thedrawbar or the trailer dimensions areoutside of the supported range. Thesystem is designed to work withdrawbars that have a license plate tohitch ball center measurement of 9–18 in(23–46 cm) when installed. The systemis designed to work with trailers thathave a hitch point to center of the axleor axles measurement of 6–33 ft(1.85–10.05 m). Do not attempt to usedrawbars or trailers that have a lengthoutside of this range as the systemperformance degrades and could causeimproper system function. Check thatthe correct trailer is selected on the
touchscreen. Verify the sticker iscorrectly applied and check that thedrawbar and the trailer dimensions arewithin the allowed range. Then, deletethe trailer from the system and repeatthe setup process to calibrate the trailer.
What does it mean when the system tellsyou to take control of the steering wheel?
The system is no longer steering thevehicle and you must take over steering.There are four reasons the system coulddisplay this message. The first reasonthe system could display this messageis that you have touched the steeringwheel when the system is steering. Thesecond reason the system could displaythis message is that you have exceededthe maximum speed for the feature. Thethird reason the system could displaythis message is that the trailer is notdetected. The final reason the systemcould display this message is that aninternal condition for system operationis not met that requires your vehicle toreturn to manual control of the steering.
What does it mean if the system does notdetect a trailer?
The system requires a clear view of thesticker placed on the trailer. You mustkeep the camera lens and sticker cleanfor the system to correctly operate. Ifthe system cannot initially detect thetrailer, it could be necessary for you tochange the lighting conditions bymoving your vehicle and trailer orwaiting until the conditions change. SeeApplying the Trailer Reversing AidSticker (page 364). Some trailers are notcompatible with the sticker and camerasystem.
Note:The system is designed to be usedwith the same trailer connection every timeyou choose the trailer from the touchscreen.When using a different drawbar or a differentpinhole on drawbars with more than one,connecting the drawbar to your vehicleaffects the trailer position and you may needto repeat the trailer setup and calibrationprocess.
