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:
0
0
e
0
Keep your speed at 55 mph (88
k m h )
or
less for the first 500 miles (805 km).
Don't drive at any one speed
--
fast or
slow
--
for the first 500 miles (805 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.
Ignition Positions

ignition key lets you turn the ignition switch to five
different positions.

like the radio and the windshield wipers when the
engine is off. To get into ACCESSORY, push in the key
and turn it toward you. Your steering wheel will remain
locked, just as it was before you inserted the key.
