Note:The electronic locking differentialmay not engage if you press your acceleratorpedal during an engagement attempt. Amessage could display in the instrumentdisplay guiding you to release theaccelerator pedal.
Note:If the electronic locking differentialhas difficulty disengaging, release theaccelerator pedal and turn the steeringwheel in the opposite direction while rolling.
Note:The electronic locking differential isfor off-road use only and is not for use ondry pavement. Using the electronic lockingdifferential on dry pavement results inincreased tire wear, noise and vibration.
Note:Do not perform this operation whencruise control or trail control are selectedand active. The system may not engage asexpected.
ELECTRONIC LOCKING
DIFFERENTIAL INDICATORS
If both rear wheel axle shaftslock together, the indicator in thecluster is amber, providingadditional traction.
If you select the electronic lockingdifferential and the indicator in the clusteris gray or turns from amber to gray whiledriving, one of the following has occurred:
•The vehicle speed is too high.
•The accelerator pedal is too high duringan engagement attempt.
•The vehicle is experiencing an anti-lockbrake activation.
•The left and right wheel speeddifference is too high during anengagement attempt.
•The system has malfunctioned andaccompanies a check lockingdifferential message in the informationdisplay. See your dealer as soon aspossible.
Note:If the vehicle is experiencing ananti-lock braking event, the electroniclocking differential could momentarilydisengage.

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.

Why is reverse braking assist unavailable?
•Make sure the reverse braking assist ison. See Switching Reverse BrakingAssist On and Off (page 298).
•Make sure that all doors, liftgate ortailgate and hood are closed. Drive thevehicle on a straight road for a shortperiod. If the message remains, havethe system checked.

•The 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 haveoccurred. Reverse braking assistresumes operation when the event iscomplete.
•Make sure the rear view camera and360 degree camera are not dirty orobstructed. If dirty, clean the camera.If the message still appears aftercleaning the camera, wait a short timefor the message to clear. If themessage does not clear, have thesystem checked.
•Make sure the cross traffic alert andrear parking aid sensors are notblocked or faulty. See Locating theCross Traffic Alert Sensors (page388). See Locating the Rear ParkingAid Sensors (page 324).
•You recently had your vehicle serviced,or the battery disconnected. Drive yourvehicle a short distance to resumesystem operation.
•Reverse braking assist does notfunction when you connect a trailer.Operation resumes when youdisconnect 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 TRACTION CONTROL
The traction control system helps to avoiddrive wheel spin and loss of traction.
HOW DOES TRACTION
CONTROL WORK
If your wheels begin to spin, the loss oftraction can compromise steering controland stability of the vehicle. The tractioncontrol system applies the brakes toindividual wheels and when needed,reduces engine power at the same time toincrease traction.
SWITCHING TRACTION
CONTROL ON AND OFF
WARNING: Operating your vehiclewith the traction control disabled couldlead to an increased risk of loss of vehiclecontrol, vehicle rollover, personal injuryand death.
The traction control system turns on eachtime you switch the ignition on.
The button for the stability and tractioncontrol system is on the instrument panel.
Press and release the button to switchtraction control off. The stability controlsystem remains fully active, to switch it off,press and hold the button for a fewseconds, then release.
When you switch traction control off, amessage and an illuminated icon appearon the instrument cluster.
Press the switch again to turn the tractioncontrol system back on to normaloperation.
If your vehicle is stuck in mud or snow,switching traction control off may bebeneficial as this allows the wheels to spin.

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.
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.
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.
Torque Vectoring by Brakes
Torque vectoring control applies braketorque on the inner driven wheel in a curvefor better traction to avoid an understeer,or oversteer situation. Unlike electronicstability control, enhanced torquevectoring control does not slow thevehicle. It helps control excessive wheelslip and gives the vehicle improvedcornering agility.
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 307).

SWITCHING STABILITY
CONTROL ON AND OFF
Stability Control turns on each time youswitch the ignition on.
You can switch the stability control off bypressing and holding the stability andtraction control button off for 5-15seconds, or you can press the button againto switch the system on.
Shifting the transmission into reverse (R)will disable the system.
You can switch the traction control systemoff or on independently. See SwitchingTraction Control On and Off (page 307).
