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.
