New Vehicle Break-In
Notice:The 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
rst 500 miles (805 km).
Do not drive at any one
constant speed, fast or slow,
for the rst 500 miles (805 km).
Do not make full-throttle
starts. Avoid downshifting to
brake or slow the vehicle.
Avoid making hard stops for
the rst 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. SeeTowing a
Trailer on page 4-42for the
trailer towing capabilities of the
vehicle and more information.
Following break-in, engine
speed and load can be gradually
increased.
