Introduction
BREAKING-IN YOUR VEHICLE
Your vehicle does not need an extensive break-in. Try not to drive
continuously at the same speed for the first 1,000 miles (1,600 km) of
new vehicle operation. Vary your speed frequently in order to give the
moving parts a chance to break in.
Drive your new vehicle at least 500 miles (800 km) before towing a
trailer. Additionally, during the first 500 miles (800 km) that you tow a
trailer, do not drive over 70 mph (112 km/h) and do not make starts at
full throttle. This style of driving will help the engine and other parts of
your vehicle break in at the heavier loads. For more detailed information
about towing a trailer, refer to Trailer towing in the Tires, Wheels and
Loading chapter.
Do not add friction modifier compounds or special break-in oils during
the first few thousand miles (kilometers) of operation, since these
additives may prevent piston ring seating. See Engine oil in the
Maintenance and Specifications chapter for more information on oil
usage.
