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.

Maintain steering wheel control at alltimes, especially in rough terrain. Sincesudden changes in terrain can result inabrupt steering wheel motion, make sureyou grip the steering wheel from theoutside. Do not grip the spokes of thesteering wheel.
Drive cautiously to avoid vehicle damagefrom concealed objects such as rocks andstumps.
Either know the terrain or examine mapsof the area before driving. Map out yourroute before driving in the area. Tomaintain steering and braking control ofyour vehicle, have all four wheels on theground and they need to be rolling, notsliding or spinning.
Driving Off-Road With Truck andUtility Vehicles
Note:Your vehicle may have a front airdam. Due to low ground clearance, you candamage it when taking your vehicle off-road.You can take the air dam off by removingthe bolts that secure it.
We design four-wheel drive vehicles fordriving on sand, snow, mud and roughterrain and they have operatingcharacteristics that are somewhatdifferent from conventional vehicles, bothon and off the road.
The transfer case supplies power to all fourwheels. On four-wheel drive vehicles, thetransfer case allows you to select different4WD modes when necessary. Becomethoroughly familiar with this informationbefore you operate your vehicle.
Four-wheel drive uses all four wheels topower your vehicle. This increases traction,enabling you to drive over terrain and roadconditions that a conventional two-wheeldrive vehicle cannot.
Basic Operating Principles
•Drive slower in strong crosswinds whichcan affect the normal steeringcharacteristics of your vehicle.
•When driving your vehicle on surfacesmade slippery by loose sand, water,gravel, snow or ice, proceed with care.
•Do not use 4H or 4L on dry, hardsurfaced roads. Doing so can produceexcessive noise, increase tire wear andcould damage drive components. Use4H or 4L modes for consistentlyslippery or loose surfaces.
If Your Vehicle Leaves the Road
If your vehicle leaves the road, reduce yourvehicle speed and avoid severe braking.When your vehicle speed decreases, easeyour vehicle back onto the road. Do notsharply turn the steering wheel whenreturning your vehicle to the road.
It may be safer to stay on the shoulder ofthe road and gradually slow down beforereturning to the road. You may lose controlif you do not slow down or if you toosharply or abruptly turn the steering wheel.
It may be less risky to strike small objects,such as freeway reflectors, with minordamage to your vehicle rather thanattempt a sudden return to the road whichcould cause your vehicle to slide sidewaysout of control or roll over. Remember, yoursafety and the safety of others should beyour primary concern.
Emergency Maneuvers
In an unavoidable emergency situationwhere you must make a sudden sharp turn,remember to avoid over-driving yourvehicle and turn the steering wheel only asrapidly and as far as required to avoid theemergency. Excessive steering can resultin loss of vehicle control. Apply smoothpressure to the accelerator pedal or brakepedal when you require changes in vehicle

speed. Avoid abrupt steering, accelerationand braking. This could result in anincreased risk of vehicle roll over, loss ofvehicle control and personal injury. Use theavailable road surface to bring your vehicleto a safe direction of travel.
In the event of an emergency stop, avoidskidding the tires and do not attempt anysharp steering wheel movements.
If your vehicle goes from one type ofsurface to another, such as concrete togravel, there can be a change in the wayyour vehicle responds to a maneuver usingsteering, acceleration or braking.
Operating Four-Wheel Drive with aSpare or Mismatched Tires
On four-wheel drive vehicles, the size ofthe spare tire can affect the four-wheeldrive system. If there is a significantdifference between the size of the sparetire and the remaining tires, you could havelimited four-wheel drive functionality,added noise, discomfort and drivelinedamage. Due to normal tire wear, yourspare tire is not necessarily the same sizeas your on-road tires, which makes yourspare tire a dissimilar size. Use the sparetire on a limited basis only. When drivingwith a dissimilar wheel and tire assemblydo not:
•Exceed 50 mph (80 km/h) with afour-wheel drive mode turned on.
•Turn on a four-wheel drive modeunless the vehicle is stationary.
•Use a four-wheel drive mode on drypavement.
Driving with the full-size dissimilar sparewheel and tire assembly can limitfour-wheel drive functionality, especiallywhen driving in a mechanically lockedfour-wheel drive mode. You can experiencethe following:
•Additional noise from the transfer caseor other drive components.
•Difficulty shifting out of a mechanicallylocked four-wheel drive mode.
•Driveline component damage.
Mechanical Shift Blocking
On vehicles with an electronicshift-on-the-fly transfer case, the transfercase distributes torque to the front wheelsby mechanically interlocking the front andrear driveshafts together. Various externalfactors can affect shifting performance ofthis type of system including, but notlimited to:
•Vehicle acceleration.
•Dissimilar tire sizes.
•High steering input.
For vehicles with an electronicshift-on-the-fly transfer case, whenshifting into two-wheel drive high on dry,hard surfaced roads, we recommend thatthe following procedure is followed toreduce the likelihood of a mechanical shiftblock:
•While driving straight, come to a stopon a flat, horizontal surface.
•Shift into park (P).
•Select 2H and wait for the 2H LED tobecome solid.
•Shift into reverse (R) and let the vehicleroll backward up to 5 ft (1 m).
•Shift into drive (D) and let the vehicleroll forward up to 5 ft (1 m).
•Driving the vehicle around a tight turnat a slow speed.
If the system is mechanically blocked, oneor more of the following actions can relievethe mechanical shift block:
•Momentary acceleration.
•Momentary braking.
•Bringing the vehicle to a stop.

“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.
