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 the 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 4-28 for the trailer towing
capabilities of your vehicle and more
information.
Following break-in, engine speed and load can be
gradually increased.
