New Vehicle "Break-In"
NOTICE:
Your modern vehicle doesn't 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
(804
km).
Don't drive at any one speed
-
fast or slow
-
for the first
500 miles (804 km). Don't make full-throttle starts.
Avoid making hard stops for the first 200 miles (322 km) or
so. During this time your new brake linings aren't 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.
Don't tow a trailer during '(break-in." See "Towing a Trailer''
in the Index for more information.
