PRINCIPLE OF OPERATION
The four-wheel drive system in your vehicleis a part-time system activated using therotary switch mounted in the centerconsole. In normal rear-wheel drive, the 2Hdrive operation system directs torque tothe rear axle. Moving the switch to 4H or4L directs drive torque to both the frontand rear axles, providing four-wheel drive.
Depending on your vehicle, furtherfour-wheel drive options may be availableon the switch panel located on the centerconsole.
USING FOUR-WHEEL DRIVE
Note:There is additional importantinformation regarding the safe operation ofthis type of vehicle in this manual. SeeGeneral Information (page 292).
Note:Do not use 4H or 4L modes on dry,hard surfaced roads. Doing so can produceexcessive noise, increase tire wear and coulddamage drive components. We intend 4Hor 4L modes only for consistently slipperyor loose surfaces. Use of 4L mode on thesesurfaces could produce some noise, suchas occasional clunks, but should notdamage drive components.
Note: When you select 4L when yourvehicle is moving, it does not perform a shiftuntil your vehicle is stationary. This is normaland is no reason for concern.
Note:You can switch on and switch off theelectronic locking differential by pressingthe locking differential button. SeeElectronic Locking Differential (page 173).
4WD Indicator Lights
Note:When a 4X4 system fault is present,the system typically remains in whichever4X4 mode you selected prior to the faultcondition occurring. It should never defaultto 4X2. When the warning displays, haveyour vehicle serviced by an authorizeddealer.

Note:It is normal to hear some noise as thesystem shifts or engages.
1.Stop your vehicle when it is safe to doso.
2.Place the transmission in neutral (N).
3.Move the transfer shift switch to thedesired position.
The information display displays amessage indicating a 4X4 shift is inprogress followed by the system modeselected. If any of the above shiftconditions are not present, the shift doesnot occur and the information displayshows information guiding you through theproper shifting procedures.
How Your Vehicle Differs FromOther Vehicles
WARNING: Vehicles with a highercenter of gravity (utility and four-wheeldrive vehicles) handle differently thanvehicles with a lower center of gravity(passenger cars). Avoid sharp turns,excessive speed and abrupt steering inthese vehicles. Failure to drive cautiouslyincreases the risk of losing control of yourvehicle, vehicle rollover, personal injuryand death.
Truck and utility vehicles can differ fromsome other vehicles. Your vehicle may behigher to allow it to travel over roughterrain without getting hung up ordamaging underbody components.
The differences that make your vehicle soversatile also make it handle differentlythan an ordinary passenger car.

“Tread Lightly” is an educational programdesigned to increase public awareness ofland-use regulations and responsibilitiesin our nation's wilderness areas. We jointhe U.S. Forest Service and the Bureau ofLand Management in encouraging you tohelp preserve our national forest and otherpublic and private lands by “treadinglightly.”
Driving on Hilly or Sloping Terrain
Although natural obstacles may make itnecessary to travel diagonally up or downa hill or steep incline, you should drivestraight up or straight down.
Note: Avoid turning on steep slopes or hills.A danger lies in losing traction, slippingsideways and possible vehicle roll over. Donot drive over the crest of a hill withoutseeing what conditions are on the other side.Do not drive in reverse over a hill without theaid of an observer. Whenever driving on ahill, determine beforehand the route youintend to use.
When climbing a steep slope or hill, startin a lower gear rather than downshifting toa lower gear from a higher gear once theascent has started. This reduces strain onthe engine and the possibility of stalling.
If your vehicle stalls, do not try to turnaround because this could cause vehicleroll over. It is better to reverse back to asafe location.
Apply just enough power to the wheels toclimb the hill. Too much power could causethe tires to slip, spin or lose traction,resulting in loss of vehicle control.
Descend a hill in the same gear you woulduse to climb up the hill to avoid excessivebrake application and brake overheating.Do not descend in neutral (N). Move thetransmission selector lever to a lower gear.When descending a steep hill, avoidsudden hard braking as you could losecontrol. Make sure the front wheels areturning so you can steer your vehicle.
If your vehicle has anti-lock brakes, steadilyapply the brakes. Do not pump the brakes.
Driving on Snow and Ice
WARNING: If you are driving inslippery conditions that require tirechains or cables, then it is critical thatyou drive cautiously. Keep speeds down,allow for longer stopping distances andavoid aggressive steering to reduce thechances of a loss of vehicle controlwhich can lead to serious injury or death.If the rear end of your vehicle slides whilecornering, steer in the direction of theslide until you regain control of yourvehicle.
Note:Excessive tire slippage can causetransmission damage

Four-wheel drive vehicles have advantagesover two-wheel drive vehicles in snow andice but can skid like any other vehicle.Should you start to slide when driving onsnowy or icy roads, turn the steering wheelin the direction of the slide until you regaincontrol.
Avoid sudden applications of power andquick changes of direction on snow andice. Apply the accelerator slowly andsteadily when starting from a full stop.
Avoid sudden braking. Although afour-wheel drive vehicle may acceleratebetter than a two-wheel drive vehicle insnow and ice, it cannot stop any faster asbraking occurs at all four wheels. Do notbecome overconfident of road conditions.
Make sure you allow sufficient distancebetween you and other vehicles forstopping. Drive slower than usual andconsider using one of the lower gears. Inemergency stopping situations, apply thebrake steadily. Do not pump the brakepedal. See Hints on Driving WithAnti-Lock Brakes (page 175).
If Your Vehicle Gets Stuck In Mud orSnow
WARNING: Do not spin the wheelsat over 34 mph (55 km/h). The tires mayfail and injure a passenger or bystander.
If your vehicle gets stuck in mud or snow,you may rock it out by shifting betweenforward and reverse gears, stoppingbetween shifts in a steady pattern. Presslightly on the accelerator in each gear.
Note:Do not rock your vehicle if the engineis not at normal operating temperature,damage to the transmission could occur.
Note:Do not rock your vehicle for morethan a minute, damage to the transmissionand tires could occur or the engine couldoverheat.
Parking
WARNING: If the parking brake isfully released, but the brake warninglamp remains illuminated, the brakesmay not be working properly. Have yourvehicle checked as soon as possible.
WARNING: Apply the parkingbrake, shift into park (P), switch theignition off and remove the key beforeyou leave your vehicle. Failure to followthis instruction could result in personalinjury or death.
On four-wheel drive vehicles, when thetransfer case is in the neutral (N) position,the engine and transmission disconnectfrom the rest of the driveline. Therefore,your vehicle is free to roll even if theautomatic transmission is in park (P) orthe manual transmission is in gear. Do notleave your vehicle unattended with thetransfer case in the neutral (N) position.Fully set the parking brake and turn off theignition when leaving your vehicle.
Maintenance and Modifications
We designed and tested the suspensionand steering systems on your vehicle toprovide predictable performance whetherloaded or empty. For this reason, westrongly recommend that you do not makemodifications such as adding or removingparts that include lift kits or stabilizer bars,or by using replacement parts notequivalent to the original factoryequipment.
We recommend that you use caution whenyour vehicle has either a high load or devicesuch as ladders or luggage racks. Anymodifications to your vehicle that raise thecenter of gravity could cause your vehicleto roll over when there is a loss of vehiclecontrol.

ELECTRONIC LOCKING
DIFFERENTIAL (IF EQUIPPED)
Note:Do not operate the system on dryhard surface roads. Doing so could lead toexcessive tire noise and wear. Use thesystem only on consistently slippery or loosesurfaces.
The system locks the left and right portionsof the rear axle together to form a soliddriving axle, resulting in increased rearwheel traction in certain conditions.
Press and hold the electronic differentiallock button for 2 seconds to activate thesystem.
Note:The lock button is on the centerconsole.
Note:Do not perform this operation whencruise control or trail control are selectedand active. The system may not engage asexpected.
The electronic differential lock can lockand unlock when the internal gears arealigned and no torque load is placed onthe differential. To aid alignment, drive thevehicle in a straight line with theaccelerator pedal released. Alternatively,drive slowly forward and backward whilemoving the steering wheel from side to sideto allow the electronic differential lock tolock.
High vehicle speed and high acceleratorpedal application inhibit the electroniclocking differential system engagement.Follow the instruction on the instrumentcluster for engagement anddisengagement.
Note:You can use the system in any drivemode 2H, 4H or 4L.
Note:When you engage the system, theElectronic Stability Program (ESP) functionssuch as Stability Control, Traction Control,Hill Descent Control, Emergency stop signal,Hill Start Assist and Trailer Sway Controlare deactivated, the ESP Off indicatorilluminates, and the HDC on indicator turnsoff.
Note:When the anti-lock braking systemis operating, the system disengages.
The electronic locking differential systemcan affect various terrain modes. SeePrinciple of Operation (page 182).
Operating Electronic LockingDifferential with Spare orMismatched Tires
The size of the spare tire can affect theperformance of the electronic lockingdifferential system. When there is asignificant size difference between the tworear tires, you could have limited electroniclocking differential functionality. If yourelectronic locking differential has difficultydisengaging, release your accelerator pedaland turn the steering wheel in the oppositedirection while rolling forward.
Note:We recommend that you engage anddisengage the electronic locking differentialwhen stopped, and a spare tire is mountedon the rear axle.

GENERAL INFORMATION
Note: Occasional brake noise is normal. Ifa metal-to-metal, continuous grinding orcontinuous squeal sound is present, thebrake linings may be worn-out and anauthorized dealer should check them. If thevehicle has continuous vibration or shudderin the steering wheel while braking, anauthorized dealer should check your vehicle.
Note: Brake dust may accumulate on thewheels, even under normal drivingconditions. Some dust is inevitable as thebrakes wear and does not contribute tobrake noise. See Cleaning the Wheels(page 289).
Wet brakes result in reduced brakingefficiency. Gently press the brake pedal afew times when driving from a car wash orstanding water to dry the brakes.
Brake Over Accelerator
In the event the accelerator pedalbecomes stuck or entrapped, apply steadyand firm pressure to the brake pedal toslow the vehicle and reduce engine power.If you experience this condition, apply thebrakes and bring your vehicle to a safestop. Switch the engine off, move thetransmission to park (P) and apply theparking brake. Inspect the acceleratorpedal and the area around it for any itemsor debris that may be obstructing itsmovement. If none are found and thecondition persists, have your vehicle towedto the nearest authorized dealer.
Emergency Brake Assist
Emergency brake assist detects when youbrake heavily by measuring the rate atwhich you press the brake pedal. Itprovides maximum braking efficiency aslong as you press the pedal. Emergencybrake assist can reduce stopping distancesin critical situations.
Anti-lock Brake System
This system helps you maintain steeringcontrol during emergency stops by keepingthe brakes from locking.
This lamp momentarilyilluminates when you switch theignition on. If the light does notilluminate during start up, remains on orflashes, the anti-lock braking system maybe disabled. Have the system checked byan authorized dealer. If the anti-lock brakesystem is disabled, normal braking is stilleffective.
See Warning Lamps and Indicators(page 92).
Note:Indicators vary depending on region.
This lamp also illuminatesmomentarily when you switchthe ignition on to confirm thelamp is functional. If it does notilluminate when you switch theignition on, or begins to flash atany time, have the system checked by anauthorized dealer. If the brake warninglamp illuminates with the parking brakereleased, have the system checkedimmediately.
HINTS ON DRIVING WITH
ANTI-LOCK BRAKES
The anti-lock brake system does noteliminate the risks when:
•You drive too closely to the vehicle infront of you.
•Your vehicle is hydroplaning.
•You take corners too fast.
•The road surface is poor.

PRINCIPLE OF OPERATION
The traction control system helps avoiddrive wheel spin and loss of traction.
If your vehicle begins to slide, the systemapplies the brakes to individual wheelsand, when needed, reduces engine powerat the same time. If the wheels spin whenaccelerating on slippery or loose surfaces,the system reduces engine power in orderto increase traction.
USING TRACTION CONTROL
WARNING: Operating your vehiclewith the traction control disabled couldlead to an increased risk of loss of vehiclecontrol, vehicle rollover, personal injuryand death.
The system automatically turns on eachtime you switch the ignition on.
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.
Switching the System Off
The switch for the stability and tractioncontrol system is on the console.
When you switch the system off, amessage and an illuminated icon appearon the instrument cluster.
Use the switch again to return the tractioncontrol system to normal operation.
Your vehicle may have MyKey restrictionsregarding this feature. See Principle ofOperation (page 59).

PRINCIPLE OF OPERATION
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 loudspeakers mayinterfere with and adversely affect theelectronic stability control system. Installany aftermarket stereo loudspeaker asfar as possible from the front centerconsole, the tunnel, and the front seatsin order to minimize the risk of interferingwith the electronic stability controlsensors. Reducing the effectiveness ofthe electronic stability control systemcould lead to an increased risk of loss ofvehicle control, vehicle rollover, personalinjury and 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 yourelectronic stability control systemactivates, SLOW DOWN.
The system automatically turns on eachtime you switch the ignition on.
If the stability control or traction controlsystem detects a fault, the following mayoccur:
•The stability and traction control lightilluminates steadily.
•The stability control and tractioncontrol systems do not enhance yourvehicle's ability to maintain traction ofthe wheels.
If the stability control or traction controlsystem activates, the following may occur:
•The stability and traction control lightflashes.
•Your vehicle slows down.
•Reduced engine power.
•A vibration in the brake pedal.
•The brake pedal is stiffer than usual.
•If the driving condition is severe andyour foot is not on the brake pedal, thepedal may move as the system applieshigher brake force.
The stability control system has severalfeatures built into it to help you maintaincontrol of your vehicle.
Electronic Stability Control
The system helps to prevent your vehicleskidding or laterally sliding by individuallyapplying the brakes to one or more wheelsand, if necessary, reducing engine power.
Roll Stability Control
The system helps to prevent rollovers bydetecting your vehicle's roll motion, andindividually applying the brakes to one ormore wheels.
Traction Control
The system enhances your vehicle's abilityto maintain traction of the wheels bydetecting and controlling wheel spin. SeeUsing Traction Control (page 178).
