GENERAL INFORMATION
WARNING: Extended idling at highengine speeds can produce very hightemperatures in the engine and exhaustsystem, creating the risk of fire or otherdamage.
WARNING: Do not park, idle ordrive your vehicle on dry grass or otherdry ground cover. The emission systemheats up the engine compartment andexhaust system, creating the risk of fire.

WARNING: Exhaust leaks mayresult in entry of harmful and potentiallylethal fumes into the passengercompartment. If you smell exhaustfumes inside your vehicle, have yourvehicle inspected immediately. Do notdrive if you smell exhaust fumes.
The powertrain control system meets allCanadian interference-causing equipmentstandard requirements regulating theimpulse electrical field or radio noise.
Note:If you use your vehicle regularly abovethe altitude of 7,500 ft (2,286 m) and underthe temperature of -4.0°F (-20°C), it isrecommended to use the alternative engineoil. See Capacities and Specifications(page 337).
If you disconnect the battery, your vehiclemay exhibit some unusual drivingcharacteristics for approximately 6 mi(10 km) after you reconnect it. This isbecause the engine management systemmust realign itself with the engine. You candisregard any unusual drivingcharacteristics during this period.
When you start the engine, avoid pressingthe accelerator pedal before and duringoperation. Only use the accelerator pedalwhen you have difficulty starting theengine.

6.If the oil level is at the minimum mark,immediately add oil.
7.Reinstall the dipstick. Make sure it isfully seated.
Note:The oil consumption of new enginesreaches its normal level after approximately3,000 mi (5,000 km).
Note:Increases in oil level can occur fromfrequent short trips that do not allow theengine to get to operating temperature, aswell as frequent idling or low speed drivingfor long periods of time.
Note:If oil levels are continuously notedabove the maximum mark, schedule a visitto your authorized dealer.

Brake Burnishing
The brakes should be properly burnishedprior to heavy track use. Excessive brakenoise may occur after the track burnish ortrack use. Perform this procedure in a safemanner on dry pavement, and incompliance with all local and stateordinances and laws regarding motorvehicle operation.
How to Burnish the Brakes
Initial low temperature bedding:
•If your brakes already have 200 mi(322 km) or more of city driving, skipthis step and go directly to the hightemperature bedding cycle procedure.Otherwise, perform at least 30 stopsfrom 50 mph (80 km/h) at 1/3 gdeceleration with 1 mi (1.2 km) spacingbetween stops. A deceleration gaugecan be accessed through theTrackApps menu in your informationdisplay.
High temperature bedding cycle:
•Beginning with cool brakes, perform 15consecutive stops back to back,accelerating at 3/4 throttle to 80 mph(128 km/h) and braking to 20 mph(32 km/h) at 1.0 g deceleration. Thebrakes may omit an odor or smokeduring this part of the procedure.
Cool down:
•Cool the brakes down by driving one ortwo laps,5 mi (8 km), at 60 mph(96 km/h) with minimal to no brakeusage.
Recovery low temperature bedding:
•Perform at least 30 stops from 50 mph(80 km/h) at 1/3 g deceleration with0.7 mi (1.2 km) spacing between stops.A deceleration gauge can be accessedthrough the TrackApps menu in yourinformation display.
