DRIVE CONTROL
WARNING
Do not use Sport, Track or Drift modewhen using a temporary spare wheelor after inflating a tire using thetemporary mobility kit.
Your vehicle has various drive modes thatcan deliver driving experiences through asuite of sophisticated electronic systems.Each mode has preset vehicle settings tooptimize steering, all-wheel drive, torquevectoring, powertrain response, suspensionand electronic stability control.
Selectable Drive Modes
Press the button.
The available modes appear in theinformation display. Repeatedly press thebutton to scroll through the availablemodes. When your desired mode appearsin the information display, wait for fourseconds while the system sets the selectedmode or press the OK button on thesteering wheel.
Note:You may not be able to choose oneof the selectable drive modes for a shorttime after starting your vehicle in coldambient temperatures.
Selectable Drive Modes
Normal
The system defaults to normalmode when you start thevehicle. Vehicle settings tunedfor street driving.
Electronic stability control and tractioncontrol systems fully enabled.
Note:When using a programmed MyKeyyou cannot switch any other mode on.
Sport
Vehicle settings tuned forperformance street driving.
Electronic stability control and tractioncontrol systems fully enabled.
Note:When using a programmed MyKeyyou cannot switch this on.
Track
This mode is for track use only.Vehicle settings tuned foraggressive driving.
The system reduces brake systemintervention from the stability controlsystem and optimizes the road-holdingability of your vehicle. Electronic stabilitycontrol is set to reduced mode while thetraction control system is disabled apartfrom the electronic limited slip differentialfunction. Engine interventions from thestability control and traction controlsystems are also disabled.
Note:When using a programmed MyKeyyou cannot switch this on.
Drift
This mode is for track use only.Vehicle settings tuned forspirited and aggressive driving.
The system reduces brake systemintervention from the stability controlsystem and increases torque transfer tothe rear axle to allow controlled oversteerdrifts.
Electronic stability control is set to reducedmode while the traction control system isdisabled apart from the electronic limitedslip differential function. Engineinterventions from the stability control andtraction control systems are also disabled.

DRIVING THROUGH WATER
Your vehicle has aerodynamic devicesattached to the underbody designed tohelp control airflow for superiorperformance. Therefore, you must beespecially careful to avoid driving throughdeep or standing water.
ENGINE OVERSPEED
WARNING
Do not operate the engine at highengine speeds while the vehicle isstationary. This can cause damagenot covered by the vehicle Warranty andcan result in serious injury.
Your vehicle has an engine speed limiterthat helps increase engine performance.A narrow red line on the tachometer faceindicates the standard maximum enginespeed. The red line thickens where theengine speed enters the overspeed limiter.
The system allows a maximum of threeseconds of engine overspeed. After this,the engine speed limiter reduces enginespeed and holds it at a predeterminedlimit. Once the engine speed drops belowthe predetermined limit, the system resetsand permits a further three seconds ofengine overspeed.
Note:Do not run the engine at high enginespeeds until it reaches the normal operatingtemperature.
ENGINE OVERBOOST
Your vehicle has an engine overboostfeature to allow additional torque delivery.The overboost feature controls a varietyof engine parameters to deliver additionaltorque. This feature widens the enginespeed range of the peak torque curve,giving maximum performance whilepassing another vehicle or launching froma standing start.
The system allows a maximum of 20seconds of engine overboost. After thisthe system reduces turbo charger boostand maximizes it at a predetermined limit.Once the turbo charger boost drops belowthe predetermined limit the system resetsand a further 20 seconds of engineoverboost is permitted.
Note:You do not need to take any actionas the system allows overboost when youdemand it.

CHANGING THE ENGINE AIR
FILTER
WARNING
To reduce the risk of vehicle damageand personal burn injuries, do notstart your engine with the air cleanerremoved and do not remove it while theengine is running.
Change the air filter element at the correctinterval. Only use the specifiedreplacement air filter. Incorrectcomponent use can cause damage notcovered by the vehicle Warranty.
When changing the engine air filter, do notallow debris or foreign material to enterthe air induction system. The engine andturbocharger are susceptible to damagefrom even small particles.
To replace the air filter element do thefollowing:
1.Remove the screws that secure the airfilter housing cover.
2.Remove the air filter housing cover.
3.Remove the air filter element from theair filter housing.

4.Wipe any dirt or debris from the air filterhousing and cover to make sure no dirtgets in the engine and that you have agood seal.
5.Install a new air filter element.
Note:Make sure you align the locating tabon the air filter element with the fork in theair filter housing.
6.Install the air filter housing cover.
7.Install the screws to secure the air filterhousing cover to the air filter housing.

We recommend that you only operate yourvehicle at high speeds at locationsdesigned to do so safely. Your vehicle haselectronic controls that may reduce poweror limit engine speed to help reducepowertrain temperatures if required.
Note:When using your vehicle on a track,have the vehicle serviced more frequently.This recommendation may not necessarilyprotect your vehicle or engine from damagein competition conditions. Increased wearand noise to certain parts of your vehiclemay also occur, for example brakes andtires. The vehicle Warranty may not covermechanical failure or damage caused toyour vehicle as a result of track use.
Steering Assistance
Steering assistance reduces andrequires more steering effortwhen you select sport or trackfrom the drive modes menu. See DriveControl (page 20).
Prolonged track driving can result in highsteering gear temperatures. If the steeringgear overheats, you will notice a furtherincrease in steering effort being required.
High steering gear temperatures can bereduced by doing any of the following:
•Reducing vehicle speed.
•Reducing steering input.
Normal track mode steering assistancereturns when the system cools down.
Note:Steering gear cooling time can bereduced if you leave the ignition switchedon while taking a pit stop.
Before Track Use
Before operating your vehicle on a track,check the following:
•Tire pressures. See Tire Pressures(page 35). Do not exceed a cold tirepressure of 50 psi (3.4 bar) for trackuse.
•Wheels and tires for wear and damage.
•Engine coolant, engine oil and brakefluid levels.
Do not operate your vehicle on a trackwhile:
•Carrying more than two peopleincluding the driver.
•Carrying cargo in the luggagecompartment.
•Carrying cargo or loose objects insideyour vehicle.
After Track Use
After track use, leave the engine runningfor a short time to allow it to reach thenormal operating temperature. Ifconditions allow, complete a cool downlap prior to taking a pit stop. Failure toallow the engine to sufficiently cool mayresult in a high coolant temperaturewarning message appearing in theinformation display.
You must replace the rear drive unit fluidafter 500 mi (800 km) of track use, or ifthe following message appears in theinformation display, whichever occurs first.
