New Vehicle Break
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
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.
Following break-in, engine speed and load can
be gradually increased.
