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.

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.
