WARNING: Do not becomeoverconfident in the ability of four-wheeldrive vehicles. Although a four-wheel drivevehicle may accelerate better than atwo-wheel drive vehicle in low tractionsituations, it won't stop any faster thantwo-wheel drive vehicles. Always drive ata safe speed.
Truck and utility vehicles can differ fromsome other vehicles. Your vehicle could behigher to allow it to travel over rough terrainwithout getting stuck or damagingunderbody components. The differences thatmake your vehicle so versatile also make ithandle differently than an ordinary passengercar. Always maintain steering wheel control,especially in rough terrain. Since suddenchanges in terrain can result in abruptsteering wheel motion, make sure you gripthe steering wheel from the outside. Do notgrip the spokes. Drive cautiously to avoidvehicle damage from concealed objects such
as rocks and stumps. Drive slower in strongcrosswinds which can affect the normalsteering characteristics of your vehicle. Beextremely careful when driving on pavementmade slippery by loose sand, water, gravel,snow or ice.
Note:Do not use four-wheel drive high orfour-wheel drive low mode on dry, hardsurfaced roads. Doing so can produceexcessive noise, increase tire wear and candamage drive components.
FOUR-WHEEL DRIVE LIMITATIONS
Operating Four-Wheel Drive with aSpare or Mismatched Tires (If Equipped)
On four-wheel drive vehicles, the size of thespare tire can affect the four-wheel drivesystem. If there is a significant differencebetween the size of the spare tire and theremaining tires, you could have limitedfour-wheel drive functionality. When drivingwith the full-size dissimilar spare wheel andtire assembly, we recommend that you donot:
•Exceed 50 mph (80 km/h) with afour-wheel drive mode turned on.
•Use a four-wheel drive mode on drypavement.
Driving with the full-size dissimilar sparewheel and tire assembly can limit four-wheeldrive functionality. You can experience thefollowing:
•Additional noise from the transfer caseor other drive components.
Use of a dissimilar spare wheel and tireassembly can lead to impairment of thefollowing:
•Comfort and noise.
•Winter weather driving capability.
•Wet driving capability.
•Four-wheel drive capability.
Note:Your vehicle could have a front airdam that can become damaged, due toreduced ground clearance, when taking yourvehicle off-road. You can remove this airdam by removing the eight bolts that secureit.

FOUR-WHEEL DRIVE AUTO
4A turns on when you select EXCITE,NORMAL 4x4 AUTO or SLIPPERY.Four-wheel drive auto provides electronicallycontrolled four-wheel drive power to boththe front and rear wheels, as required, forincreased traction in varying on-roadconditions. The four-wheel drive auto tuningvaries based on selected Drive Mode. SeeSelecting a Drive Mode (page 295).
Note:Four-wheel drive auto can turn on oroff automatically based on Drive Modeselection. See Selecting a Drive Mode (page295).
FOUR-WHEEL DRIVE HIGH
4H turns on when you select DEEPCONDITIONS. Four-wheel drive highprovides electronically locked four-wheeldrive power to both the front and rear wheelsfor use in off-road or winter conditions suchas deep snow, sand or mud. This mode isnot for use on dry pavement.
Note:Four-wheel drive high can turn on oroff automatically based on Drive Modeselection. See Selecting a Drive Mode (page295).
FOUR-WHEEL DRIVE LOW
This mode turns on when you select SLOWCLIMB. It provides electronically lockedfour-wheel drive power to both the front andrear wheels for use on low traction surfaces,and does so with additional gearing forincreased torque multiplication. This modeis only for off-road conditions, such as deepsand, steep slopes, or pulling heavy objects.
Note:Four-wheel drive low can turn on oroff automatically based on drive modeselection. See Selecting a Drive Mode (page295).

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 you donot intervene the vehicle may start to moveagain.
Note:Certain add-on devices around thebumper or fascia may create false alerts. Forexample, 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 small ormoving objects, particularly those close tothe ground.
Note:The system does not operate duringhard acceleration or steering.
Note:If your vehicle sustains damage to thebumper or fascia leaving it misaligned orbent, it could alter the sensing zone causinginaccurate measurement of obstacles orfalse 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, the systemmay detect the trailer and provide an alert,or the system turns off. If the system doesnot turn off, manually switch the system offafter 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.

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, reducesengine power at the same time to increasetraction.
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 system turns traction control and stabilitycontrol on each time you power on yourvehicle.
1.Press Features on the touchscreen.
2.Press Driver Assistance.
3.Switch Traction Control on or off.
Note:When you switch traction control off,a message and an illuminated icon appearon the information display.
Turn the system back on to return to normaloperation.
If your vehicle is stuck in mud or snow,switching traction control off may bebeneficial as this allows the wheels to spin.
Note:When you switch traction control off,stability control remains fully active.
Your vehicle could have MyKey restrictionsregarding this feature. See ConfigurableMyKey Settings (page 82).
TRACTION CONTROL INDICATOR
Stability and Traction Control Indicator
If the indicator does not illuminatewhen you switch the ignition on,or remains on when the engine isrunning, this indicates a malfunction. Haveyour vehicle checked by an authorizeddealer as soon as possible.
The traction control off indicatorilluminates when you switch thetraction control system off, or whenan alternative stability control mode isselected that requires the traction control offdepending on the drive mode selected.
