FOUR-WHEEL DRIVE
LIMITATIONS
Operating Four-Wheel Drive witha Spare or Mismatched Tires (If
Equipped)
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.When driving with the full-size dissimilarspare wheel and tire assembly, werecommend that you do not:
•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 limitfour-wheel drive functionality. You canexperience the following:
•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.

TIRE QUALITY GRADES
Tire Quality Grades apply to newpneumatic passenger car tires.The Quality grades can be foundwhere applicable on the tiresidewall between tread shoulderand maximum section width. Forexample: Treadwear 200Traction AA Temperature A.
These Tire Quality Grades aredetermined by standards that theUnited States Department ofTransportation has set.
Tire Quality Grades apply to newpneumatic passenger car tires.They do not apply to deep tread,winter-type snow tires,space-saver or temporary usespare tires, light truck or LT typetires, tires with nominal rimdiameters of 10 to 12 inches orlimited production tires as definedin Title 49 Code of FederalRegulations Part 575.104 (c)(2).
U.S. Department ofTransportation Tire qualitygrades: The U.S. Department ofTransportation requires us to giveyou the following informationabout tire grades exactly as thegovernment has written it.
Treadwear
The treadwear grade is acomparative rating based on thewear rate of the tire when testedunder controlled conditions on aspecified government test course.For example, a tire graded 150would wear 1½ times as well onthe government course as a tiregraded 100. The relativeperformance of tires dependsupon the actual conditions of theiruse, however, and may departsignificantly from the norm due tovariations in driving habits, servicepractices, and differences in roadcharacteristics and climate.

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.
