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.

LOCATING THE TIRE LABEL
You will find a Tire Label containing tireinflation pressure by tire size and otherimportant information located on theB-Pillar or the edge of the driver's door.See Locating the Safety ComplianceCertification Labels (page 337).

QUALITY GRADES
Tire Quality Grades apply to newpneumatic passenger car tires. TheQuality grades can be found whereapplicable on the tire sidewall betweentread shoulder and maximum sectionwidth. For example: Treadwear 200Traction AA Temperature A.
These Tire Quality Grades aredetermined by standards that the UnitedStates Department of Transportation hasset.
Tire Quality Grades apply to newpneumatic passenger car tires. They donot apply to deep tread, winter-typesnow tires, space-saver or temporaryuse spare tires, light truck or LT typetires, tires with nominal rim diameters of10 to 12 inches or limited production tires
as defined in Title 49 Code of FederalRegulations Part 575.104 (c)(2).
U.S. Department of Transportation Tirequality grades: The U.S. Department ofTransportation requires us to give youthe following information about tiregrades exactly as the government haswritten it.
Treadwear
The treadwear grade is a comparativerating based on the wear rate of the tirewhen tested under controlled conditionson a specified government test course.For example, a tire graded 150 wouldwear 1½ times as well on thegovernment course as a tire graded 100.The relative performance of tiresdepends upon the actual conditions oftheir use, however, and may departsignificantly from the norm due tovariations in driving habits, servicepractices, and differences in roadcharacteristics and climate.
Traction AA A B C
WARNING: The traction gradeassigned to this tire is based onstraight-ahead braking traction tests,and does not include acceleration,cornering, hydroplaning or peaktraction characteristics.

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.
