Vehicle break-in process
By following a few simple precautions for the first 600 miles (1,000 km) you may add to the performance, economy and life of your vehicle.
-
Do not race the engine.
-
While driving, keep your engine speed (rpm, or revolutions per minute) between 2,000 rpm and 4,000 rpm.
-
Do not maintain a single engine speed for long periods of time, either fast or slow. Varying engine speeds is needed to properly break-in the engine.
-
Avoid hard stops, except in emergencies, to allow the brakes to seat properly.
-
Don't tow a trailer during the first 1,200 miles (2,000 km) of operation.
-
Fuel economy and engine performance may vary depending on vehicle break-in process and be stabilized after 4,000 miles (6,000 km). New engines may consume more oil during the vehicle break-in period.
