New Vehicle "Break-ln"
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.
