New Vehicle Break-In

Notice: Your vehicle does not need an
elaborate break-in. But it will perform better in
the long run if you follow these guidelines:
•
Keep your speed at 55 mph (88 km/h)
or less for the first 500 miles (805 km).
•
Do not drive at any one constant speed, fast
or slow, for the first 500 miles (805 km). Do
not make full-throttle starts. Avoid
downshifting to brake, or slow, the vehicle.

•
Avoid making hard stops for the first
200 miles (322 km) or so. During this time
®
system is
your new brake linings are not yet broken
in. Hard stops with new linings can mean
®
premature wear and earlier replacement.
Follow this breaking-in guideline every time
you get new brake linings.
•
Do not tow a trailer during break-in. See
Towing a Trailer on page 363 for the trailer
towing capabilities of your vehicle and more
information.
Following break-in, engine speed and load can
be gradually increased.
