HOW DOES ALL-WHEEL DRIVE
WORK
All-wheel drive uses all four wheels to powerthe vehicle. This increases traction, enablingyou to drive over terrain and road conditionsthat a conventional two-wheel drive vehiclecannot. The AWD system turns on whenneeded and does not require input from you.
There is further information on driving inunique driving conditions. See Driving Hints(page 313).
ALL-WHEEL DRIVE PRECAUTIONS
WARNING: Do not becomeoverconfident in the ability of all-wheeldrive vehicles. Although an all-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.
ALL-WHEEL DRIVE LIMITATIONS
Using different size tires other than theprovided spare could cause system damageor disable the all-wheel drive system.

HOW DOES STABILITY CONTROL
WORK
WARNING: Vehicle modificationsinvolving braking system, aftermarket roofracks, suspension, steering system, tireconstruction and wheel and tire size maychange the handling characteristics of yourvehicle and may adversely affect theperformance of the electronic stabilitycontrol system. In addition, installing anystereo loudspeakers may interfere withand adversely affect the electronic stabilitycontrol system. Install any aftermarketstereo loudspeaker as far as possible fromthe front center console, the tunnel, andthe front seats in order to minimize the riskof interfering with the electronic stabilitycontrol sensors. Reducing theeffectiveness of the electronic stabilitycontrol system could lead to an increasedrisk of loss of vehicle control, vehiclerollover, personal injury and death.
WARNING: Remember that evenadvanced technology cannot defy the lawsof physics. It's always possible to losecontrol of a vehicle due to inappropriatedriver input for the conditions. Aggressivedriving on any road condition can causeyou to lose control of your vehicleincreasing the risk of personal injury orproperty damage. Activation of theelectronic stability control system is anindication that at least some of the tireshave exceeded their ability to grip theroad; this could reduce the operator'sability to control the vehicle potentiallyresulting in a loss of vehicle control, vehiclerollover, personal injury and death. If yourelectronic stability control system activates,SLOW DOWN.
If a driving condition activates either thestability control or the traction control systemyou may experience the following conditions:
•The stability and traction control lightflashes.
•Your vehicle slows down.
•Reduced engine power.
The stability control system has severalfeatures built into it to help you maintaincontrol of your vehicle:
Electronic Stability Control
Electronic stability control enhances yourvehicle’s ability to prevent skids or lateralslides by applying brakes to one or more ofthe wheels individually and, if necessary,reducing engine power.
Roll Stability Control
Roll stability control enhances your vehicle’sability to prevent rollovers by detecting yourvehicle’s roll motion and the rate at which itchanges by applying the brakes to one ormore wheels individually.

The traction grades, from highest tolowest are AA, A, B, and C. The gradesrepresent the tire’s ability to stop on wetpavement as measured under controlledconditions on specified government testsurfaces of asphalt and concrete. A tiremarked C may have poor tractionperformance.
Temperature A B C
WARNING: The temperaturegrade for this tire is established for atire that is properly inflated and notoverloaded. Excessive speed,underinflation, or excessive loading,either separately or in combination,can cause heat buildup and possible
tire failure.
The temperature grades are A (thehighest), B and C, representing the tire’sresistance to the generation of heat andits ability to dissipate heat when testedunder controlled conditions on aspecified indoor laboratory test wheel.Sustained high temperature can cause
the material of the tire to degenerateand reduce tire life, and excessivetemperature can lead to sudden tirefailure. The grade C corresponds to alevel of performance which allpassenger car tires must meet under theFederal Motor Vehicle Safety StandardNo. 139. Grades B and A representhigher levels of performance on thelaboratory test wheel than the minimumrequired by law.
