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.

GENERAL MAINTENANCE
INFORMATION
Protecting Your Investment
Your vehicle is equipped with an intelligentoil life monitoring system. Under normaloperating conditions, a message appearsin the information display to indicate theregular oil change interval. Highperformance vehicles tend to be driven insuch a way that the engine experienceshigh speed and high load. As a result, someoil consumption could occur and themessage appears earlier than the regularoil change interval. If you drive your vehiclethis way, we recommend that you checkthe engine oil level every 2,000 mi(3,000 km) and fill the engine to themaximum mark on the engine oil dipstick.
Note:Do not add oil further than themaximum mark.
