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.

Note:Your vehicle could have side stepsthat can become damaged, due to reducedground clearance, when taking your vehicleoff-road. Remove side steps before drivingyour vehicle off-road.
SELECTING A FOUR-WHEEL DRIVE
MODE
To select a specific four-wheel drive modeplease select one of the desired drivemodes. For additional information. SeeSelecting a Drive Mode (page 295).
Note:When shifting to and from four-wheeldrive, a message appears in the instrumentcluster display indicating that the system isin the process of making a shift.
Note:Do not perform this operation if therear wheels are slipping or while applyingthe accelerator pedal.
If the system detects a fault, a warningmessage appears in the instrument clusterdisplay. See Four-Wheel Drive –Information Messages (page 228).
Note:Do not use DEEP CONDITIONS orSLOW CLIMB on dry, hard surfaced roads.Doing so produces excessive noise,increases tire wear and may damage drivecomponents. The 4X4 system in thesemodes is only intended for consistentlyslippery or loose surfaces.
Shifting to or from Slow Climb (4L)
To select or exit SLOW CLIMB (4L):
1.Bring your vehicle to a speed of 3 mph(5 km/h) or less.
2.Place the transmission in neutral (N).
3.Select SLOW CLIMB on the drive modeswitch.
A message appears in the instrument clusterdisplay indicating a four-wheel drive shift isin progress. If any of the above shiftconditions are not present, the shift will notoccur and a message appears in theinstrument cluster display guiding youthrough the proper shifting procedures. Ifthere is a transfer case tooth blockage, amessage appears in the instrument cluster
display. To alleviate this condition, place thetransmission in a forward gear, move yourvehicle forward approximately 4.9 ft (1.5 m),and shift the transmission back to neutral (N)to allow the transfer case to complete therange shift.
Note:You could hear some noise as thesystem shifts or engages which is normal. Ifthe system detects a fault, a warningmessage appears in the instrument clusterdisplay. See Four-Wheel Drive –Information Messages (page 228).
FOUR-WHEEL DRIVE MODES
TWO-WHEEL DRIVE HIGH
2H turns on when you select NORMAL orCONSERVE. Two-wheel drive high is forgeneral on-road driving. Power is sent to therear wheels only.
Note:Two-wheel drive high can turn on oroff based on Drive Mode selection See DriveMode Control (page 294).

CHANGING A FLAT TIRE
If you get a flat tire when driving, do notapply the brake heavily. nstead, graduallydecrease your speed, hold the steeringwheel firmly and slowly move to a safe placeon the side of the road.
Have the flat serviced by an authorizeddealer to prevent damage to the systemsensors. See Tire Pressure MonitoringSystem (page 453). Replace the spare tirewith a road tire as soon as possible. Duringrepairing or replacing of the flat tire, havethe authorized dealer inspect the systemsensor for damage.
Note:Only use tire sealants in roadsideemergencies as they may cause damage tothe tire pressure monitoring system sensor.
Note:The tire pressure monitoring systemindicator light illuminates when the sparetire is in use. To restore the full function ofthe monitoring system, all road wheels withtire pressure monitoring sensors must bemounted on this vehicle.
Dissimilar Spare Wheel and TireAssembly Information
WARNING: Failure to follow theseguidelines could result in an increased riskof loss of vehicle control, injury or death.
If you have a dissimilar spare wheel and tire,then it is intended for temporary use only.This means that if you need to use it, youshould replace it as soon as possible with aroad wheel and tire assembly that is thesame size and type as the road tires andwheels that were originally provided. If thedissimilar spare tire or wheel is damaged, itshould be replaced rather than repaired.
A dissimilar spare wheel and tire assemblyis defined as a spare wheel and tire assemblythat is different in brand, size or appearancefrom the other road tires and wheels on yourvehicle.
Full-size dissimilar spare
When driving with the full-size dissimilarspare wheel and tire assembly, do not:
•Exceed 70 mph (113 km/h).
•Use more than one dissimilar sparewheel and tire assembly at a time.
•Use snow chains on the end of thevehicle with the dissimilar spare wheeland tire assembly.
When driving with the full-size dissimilarspare wheel and tire assembly, it isrecommended that you do not:
•Exceed 50 mph (80 km/h) in four-wheeldrive.
•Engage four-wheel drive unless thevehicle is stationary.
•Use four-wheel drive on dry pavement.
Using a dissimilar spare wheel and tireassembly can compromise the effectivenessof the following:
•Handling, stability and brakingperformance.
•Comfort and noise.
•Ground clearance and parking at curbs.
•Winter weather driving capability.
