USING ALL-WHEEL DRIVE
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 is active all the timeand requires no input from the operator.
Note:Your AWD vehicle is not intended foroff-road use. The AWD feature gives yourvehicle some limited off-road capabilities inwhich driving surfaces are relatively level,obstruction-free and otherwise similar tonormal on-road driving conditions. Operatingyour vehicle under other than thoseconditions could subject the vehicle toexcessive stress which might result indamage which is not covered under yourwarranty.
Note:A warning message will be displayedin the information display when an AWDsystem fault is present See InformationMessages (page 125). An AWD system faultwill cause the AWD system to default tofront-wheel drive only mode. When thiswarning message is displayed, have yourvehicle serviced at an authorized dealer
Note:A warning message will be displayedin the information display if the AWD systemhas overheated See Information Messages(page 125). This condition may occur if thevehicle was operated in extreme conditionswith excessive wheel slip, such as deepsand. To resume normal AWD function assoon as possible, stop the vehicle in a safelocation and stop the engine for at least 10minutes. After the engine has been restartedand the AWD system has adequately cooled,the warning message will turn off and normalAWD function will return.
Do not use a spare tire of a different sizeother than the tire provided. If the mini-sparetire is installed, the AWD system may disableautomatically and enter front-wheel driveonly mode to protect driveline components.This condition will be indicated by a warningin the information display See InformationMessages (page 125). If there is a warningmessage in the information display fromusing the spare tire, this indicator should turnoff after reinstalling the repaired or replacednormal road tire and cycling the ignition offand on. It is recommended to reinstall the
repaired or replaced road tire as soon aspossible. Major dissimilar tire sizes betweenthe front and rear axles could cause the AWDsystem to stop functioning and default tofront-wheel drive or damage the AWDsystem.
Driving In Special Conditions With All-Wheel Drive (AWD)
AWD vehicles are equipped for driving onsand, snow, mud and rough roads and haveoperating characteristics that are somewhatdifferent from conventional vehicles, both onand off the highway.
Under severe operating conditions, the A/Cmay cycle on and off to protect overheatingof the engine.
Basic operating principles in specialconditions
•Drive slower in strong crosswinds whichcan affect the normal steeringcharacteristics of your vehicle.
•Be extremely careful when driving onpavement made slippery by loose sand,water, gravel, snow or ice.

PRINCIPLE OF OPERATION
WARNINGS
Vehicle modifications involving brakingsystem, aftermarket roof racks,suspension, steering system, tireconstruction and wheel and tire size maychange the handling characteristics of yourvehicle and may adversely affect theperformance of the electronic stability controlsystem. In addition, installing any stereoloudspeakers may interfere with andadversely affect the electronic stabilitycontrol system. Install any aftermarket stereoloudspeaker as far as possible from the frontcenter console, the tunnel, and the frontseats in order to minimize the risk ofinterfering with the electronic stability controlsensors. Reducing the effectiveness of theelectronic stability control system could leadto an increased risk of loss of vehicle control,vehicle rollover, personal injury and death.
WARNINGS
Remember that even advancedtechnology cannot defy the laws ofphysics. It’s always possible to lose controlof a vehicle due to inappropriate driver inputfor the conditions. Aggressive driving on anyroad condition can cause you to lose controlof your vehicle increasing the risk of personalinjury or property damage. Activation of theelectronic stability control system is anindication that at least some of the tires haveexceeded their ability to grip the road; thiscould reduce the operator’s ability to controlthe vehicle potentially resulting in a loss ofvehicle control, vehicle rollover, personalinjury and death. If your electronic stabilitycontrol system activates, SLOW DOWN.
The system automatically turns on each timeyou switch the ignition on.
If a fault occurs in either the stability controlor the traction control system, you mayexperience the following conditions:
•The stability and traction control lightilluminates steadily.
•The stability control and traction controlsystems do not enhance your vehicle'sability to maintain traction of the wheels.
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.
•A vibration in the brake pedal.
•The brake pedal is stiffer than usual.
•If the driving condition is severe and yourfoot is not on the brake, the brake pedalmay move as the system applies higherbrake force.
The stability control system has severalfeatures built into it to help you maintaincontrol of your vehicle:

Stability Control

Parallel Park Out Assist automatically steersyour vehicle out of a parallel parking space(hands-free) while you control theaccelerator, gearshift and brakes. The systemvisually and audibly guides you to entertraffic.
The system may not correctly operate in anyof the following conditions:
•You use a spare tire or a tire significantlyworn more than the other tires.
•One or more tires are improperly inflated.
•You try to park on a tight curve.
•Something passes between the frontbumper and the parking space. Forexample, a pedestrian or cyclist.
•The edge of the neighboring parkedvehicle is high off the ground. Forexample, a bus, tow truck or flatbedtruck.
•The weather conditions are poor. Forexample, during heavy rain, snow or fog.
Note: Keep the sensors on the bumper orfascia free from snow, ice and largeaccumulations of dirt. Covered sensors canaffect the system's accuracy. Do not cleanthe sensors with sharp objects.
Note:The sensors may not detect objectswith surfaces that absorb ultrasonic wavesor cause ultrasonic interference. Forexample, motorcycle exhaust, truck airbrakes or horns.
Note:Following a change in tire size, thesystem must recalibrate and operation maybe impaired for a short time.
Do not use the system if:
•You have attached a foreign object closeto the sensors on the front or rear of yourvehicle. For example, a bike rack ortrailer.
•You attach an overhanging object to theroof. For example, a surfboard.
•A foreign object damages or obstructsthe front or rear bumper or side sensors.
•The correct tire size is not in use on yourvehicle. For example, a mini-spare tire.
Using Active Park Assist - Parallel Parking
Press the Active Park Assist buttononce to search for a parallelparking space.
When driving at a speed less than 22 mph(35 km/h), the system automatically scansboth sides of your vehicle for an availableparking space. The system displays amessage and a corresponding graphic toindicate it is searching for a parking space.Use the direction indicator to selectsearching either to the left-hand side orright-hand side of your vehicle.
Note:If the direction indicators are not used,the system defaults to the passenger sideof your vehicle.

Parking AidsE146186

Possible CauseSymptom
Improperly parked vehicles or objects are boarding the space.
Your vehicle is too far past the parking space. The system performs best when you drivethe same distance past the parking space.
You have incorrectly installed or maintained the tires. For example, not inflated correctly,improper size, or of different sizes.
A repair or alteration changes the detection capabilities.
A parked vehicle has a high attachment. For example, a salt sprayer, snowplow or movingtruck bed.
The parking space length or position of parked objects changes after your vehicle passesthe space.
The temperature around your vehicle quickly changes. For example, driving from aheated garage into the cold, or after leaving a car wash.

Do not use the system in poor visibility,for example fog, heavy rain, spray orsnow.
WARNINGS
Do not use the system when towing atrailer with aftermarket trailer brakecontrols. Aftermarket trailer brakes will notfunction properly when you switch thesystem on because the brakes areelectronically controlled. Failing to do so mayresult in loss of vehicle control, which couldresult in serious injury.
Do not use tire sizes other than thoserecommended because this can affectthe normal operation of the system. Failureto do so may result in a loss of vehiclecontrol, which could result in serious injury.
Adaptive cruise control may not detectstationary or slow moving vehiclesbelow 6 mph (10 km/h).
Adaptive cruise control does not detectpedestrians or objects in the road.
Adaptive cruise control does not detectoncoming vehicles in the same lane.
Adaptive cruise control is not a crashwarning or avoidance system.
Note:It is your responsibility to stay alert,drive safely and be in control of the vehicleat all times.
The system adjusts your vehicle speed tomaintain the set gap between you and thevehicle in front of you in the same lane. Youcan select four gap settings.
The system uses a radar sensor that projectsa beam directly in front of your vehicle.

BREAKING-IN
You need to break in new tires forapproximately 300 mi (480 km). During thistime, your vehicle may exhibit some unusualdriving characteristics.
Avoid driving too fast during the first 1,000 mi(1,600 km). Vary your speed frequently andchange up through the gears early. Do notlabor the engine.
Do not tow during the first 1,000 mi(1,600 km).
REDUCED ENGINE PERFORMANCE
WARNING
If you continue to drive your vehiclewhen the engine is overheating, theengine could stop without warning. Failureto follow this instruction could result in theloss of control of your vehicle.
If the engine coolant temperature gaugeneedle moves to the upper limit position, theengine is overheating. See Gauges (page111).
You must only drive your vehicle for a shortdistance if the engine overheats. Thedistance you can travel depends on ambienttemperature, vehicle load and terrain. Theengine continues to operate with limitedpower for a short period of time.
If the engine temperature continues to rise,the fuel supply to the engine reduces. Theair conditioning switches off and the enginecooling fan operates continually.
1. Gradually reduce your speed and stopyour vehicle as soon as it is safe to doso.
2. Immediately switch the engine off toprevent severe engine damage.
3. Wait for the engine to cool down.
4. Check the coolant level. See EngineCoolant Check (page 316).
5. Have your vehicle checked as soon aspossible.
ECONOMICAL DRIVING
Fuel economy is affected by several thingssuch as how you drive, the conditions youdrive under and how you maintain yourvehicle.
There are some things to keep in mind thatmay improve your fuel economy:
•Accelerate and slow down in a smooth,moderate fashion.
•Drive at steady speeds.
•Anticipate stops; slowing down mayeliminate the need to stop.
•Combine errands and minimizestop-and-go driving (When runningerrands, go to the furthest destinationfirst and then work your way back home).
•Close the windows for high-speeddriving.
•Drive at reasonable speeds.
•Keep the tires properly inflated and useonly the recommended size.
•Use the recommended engine oil.
•Perform all regularly scheduledmaintenance.

Driving Hints

GENERAL INFORMATION
Notice to utility vehicle and truckowners
WARNINGS
Utility vehicles have a significantlyhigher rollover rate than other types ofvehicles. To reduce the risk of serious injuryor death from a rollover or other crash youmust avoid sharp turns and abruptmaneuvers, drive at safe speeds for theconditions, keep tires properly inflated, neveroverload or improperly load your vehicle,and make sure every passenger is properlyrestrained.
In a rollover crash, an unbelted personis significantly more likely to die thana person wearing a seat belt. All occupantsmust wear seat belts, and children andinfants must use appropriate restraints tominimize the risk of injury or ejection.
Utility vehicles and trucks handle differentlythan passenger cars in the various drivingconditions that are encountered on streets,highways and off-road. Utility vehicles andtrucks are not designed for cornering atspeeds as high as passenger cars any morethan low-slung sports cars are designed toperform satisfactorily under off-roadconditions.
Study your owner's manual and anysupplements for specific information aboutequipment features, instructions for safedriving and additional precautions to reducethe risk of an accident or serious injury.
All-wheel drive system (if equipped)
WARNING
Do not become overconfident in theability of all-wheel-drive vehicles.Although an all-wheel-drive vehicle mayaccelerate better than a two-wheel drivevehicle in low traction situations, it will notstop any faster than two-wheel drivevehicles. Always drive at a safe speed.
A vehicle equipped with all-wheel drive hasthe ability to use all four wheels to poweritself. This increases traction which mayenable you to safely drive over terrain androad conditions that a conventionaltwo-wheel drive vehicle cannot.
For all-wheel-drive vehicles, a spare tire ofa different size other than the tire providedshould never be used. A dissimilar spare tiresize (other than the spare tire provided) ormajor dissimilar tire sized between the frontand rear axles could cause theall-wheel-drive system to stop functioningand default to front-wheel drive.

depends 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 grade assigned to thistire is based on straight-aheadbraking traction tests, and does notinclude acceleration, cornering,hydroplaning or peak tractioncharacteristics.
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 temperature grade for this tireis established for a tire that isproperly inflated and not overloaded.Excessive speed, underinflation, orexcessive loading, either separately orin combination, can cause heat buildupand 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 causethe material of the tire to degenerate
and reduce tire life, and excessivetemperature can lead to sudden tirefailure. The grade C corresponds to alevel of performance which all
passenger 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.

A. P: Indicates a tire, designated by theTire and Rim Association, that may beused for service on cars, sport utilityvehicles, minivans and light trucks. Note:If your tire size does not begin with aletter this may mean it is designated byeither the European Tire and RimTechnical Organization or the Japan TireManufacturing Association.
B. 215: Indicates the nominal width ofthe tire in millimeters from sidewall edgeto sidewall edge. In general, the largerthe number, the wider the tire.
C. 65: Indicates the aspect ratio whichgives the tire's ratio of height to width.
D. R: Indicates a radial type tire.
E. 15: Indicates the wheel or rim
diameter in inches. If you change yourwheel size, you will have to purchasenew tires to match the new wheeldiameter.
F. 95: Indicates the tire's load index. Itis an index that relates to how muchweight a tire can carry. You may find thisinformation in your owner’s manual. Ifnot, contact a local tire dealer.
Note:You may not find this informationon all tires because it is not required byfederal law.
G. H: Indicates the tire's speed rating.The speed rating denotes the speed atwhich a tire is designed to be driven forextended periods of time under astandard condition of load and inflationpressure. The tires on your vehicle mayoperate at different conditions for loadand inflation pressure. These speedratings may need to be adjusted for thedifference in conditions. The ratings
range from 81 mph (130 km/h) to186 mph (299 km/h). These ratings arelisted in the following chart.
