All-Wheel Drive
Action and DescriptionMessage
Displays when the system has been automatically disabledto protect itself. This is caused by operating the vehicle witha severely mismatched tire installed, if the system is over-heating or if there is an issue with another vehicle systempreventing AWD operation. Overheating is most likely to occurif the vehicle is operated in severe conditions, for exampletrack use, or if there is excessive wheel slip, for example yourvehicle become stuck in mud.
AWD OFF
The system resumes normal function and clears this messageafter:
•You switch the ignition off and on and drive a shortdistance with the correct wheels and tires installed.
•The system is allowed to cool.
•Other vehicle system issues are resolved.
Displays in conjunction with an amber Information icon if thesystem is not operating correctly and defaults to front-wheeldrive only. If the warning remains on or continues appear,have your vehicle checked as soon as possible.
AWD Malfunction ServiceRequired
Displays when the rear drive unit lubrication requires changing.This message may appear if the vehicle is used for extended
periods of extreme driving, for example track use.*
AWD System Oil ChangeDue
*The rear drive unit does not require any normal scheduled maintenance. The systemelectronically monitors the rear drive unit and notifies you of required service by displayingthe message in the information display. The lubricant is more likely to require changingif you use your vehicle for extended periods of extreme driving, for example track use. Donot check or change the lubricant unless the rear drive unit shows signs of leakage or themessage displays. If the rear drive unit is submerged in water or to reset the message,have your vehicle checked as soon as possible.

FUEL QUALITY
Choosing the Right Fuel
Use only premium unleaded gasoline witha minimum pump (R+M)/2 octane ratingof 91. For optimal performance, usepremium unleaded gasoline with an octanerating of 93 or higher.
The use of the correct fuel is an importantpart of the proper maintenance of yourvehicle, and a condition of the vehicleWarranty. For this vehicle, the use ofgasoline with an octane level of 91 orhigher is required. The use of gasoline withan octane rating lower than 91 willinvalidate the vehicle Warranty. It candegrade vehicle performance and lead tosevere mechanical damage.
Note:Use of any fuel other than thoserecommended can impair the emissioncontrol system and cause a loss of vehicleperformance.
Do not use:
•Diesel fuel.
•Fuels containing kerosene or paraffin.
•Fuel containing more than 15% ethanolor E85 fuel.
•Fuels containing methanol.
•Fuels containing metallic-basedadditives, including manganese-basedcompounds.
•Fuels containing the octane boosteradditive, methylcyclopentadienylmanganese tricarbonyl (MMT).
•Leaded fuel (using leaded fuel isprohibited by law).
The use of fuels with metallic compoundssuch as methylcyclopentadienylmanganese tricarbonyl (commonly knownas MMT), which is a manganese-basedfuel additive, will impair engineperformance and affect the emissioncontrol system.
Do not be concerned if the enginesometimes knocks lightly. However, if itknocks heavily under most drivingconditions while you are using fuel with therecommended octane rating, contact anauthorized dealer to prevent any enginedamage.

USING ALL-WHEEL DRIVE
Your vehicle has All-Wheel Drive withDynamic Torque Vectoring. This featureuses all four wheels to power the vehicleand independently controls the torque toeach rear wheel. The system also has theability to over speed the outside rear wheelwhile cornering. This increases traction andhandling performance giving your vehicleroad holding capabilities that are superiorto conventional two-wheel drive andfour-wheel drive vehicles. The system isactive all the time and requires no inputfrom the driver. The system has differentDrive Mode calibration settings thatoptimize all-wheel drive performance forvarious conditions. See Drive Control(page 20).
Your vehicle is not intended for off-roaduse in the same way as an all-terrainvehicle. The all-wheel drive feature givesyour vehicle some limited off-roadcapabilities where driving surfaces arerelatively level, obstruction-free and similarto normal on-road driving conditions.Operating your vehicle under other thanthose conditions could subject the vehicleto excessive stress which can result indamage not covered by the vehicleWarranty.
The rear drive unit does not require anynormal scheduled maintenance. Thesystem is electronically monitored and anyrequired service messages appear in theinformation display. The rear drive unitlubricants may require changing if you useyour vehicle for extended periods of highspeed driving, for example track use. Youare not required to check or change therear drive unit lubricant unless there aresigns of leakage or a message appears inthe information display indicating that theunit requires service.
Using Mismatched Tires or Wheels
WARNINGS
Only use replacement tires andwheels that are of the same size,load index, speed rating and type asthose originally fitted to your vehicle.
Using a tire or wheel that is notrecommended can affect the safetyand performance of your vehicle andcould result in a loss of vehicle control,vehicle rollover, personal injury or death.
The recommended tire and wheel size canbe found on either the Safety ComplianceCertification Label or the tire informationlabel on the left-hand B-pillar or left-handfront door. If this information is not locatedas stated contact an authorized dealer assoon as possible.
Note:Using a tire or wheel that is notrecommended could cause steering,suspension, axle, power transfer unit or reardrive unit failure. Incorrect tire or wheel usecan cause damage not covered by thevehicle Warranty.
Your vehicle does not have a spare tire. Wedo not recommend using a mismatchedtire or spare wheel. However, in anemergency, the system can tolerate amismatched tire or spare wheel of adifferent size to the original for a shortjourney. The system may automaticallyenter front-wheel drive only mode toprotect driveline components. An all-wheeldrive off warning message may appear inthe information display if you install amismatched tire or spare wheel. SeeInformation Messages (page 8). Themessage turns off after you reinstall thecorrect wheel and tire and you switch theignition off and on. We recommend thatyou reinstall the repaired or replaced wheeland tire as soon as possible.
