Starting and
Operating
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 88 km/h
(55 mph) or less for the
first 805 km (500 miles).
. Do not drive at any
one constant speed, fast
or slow, for the first 805 km
(500 miles). Do not make
full-throttle starts. Avoid
downshifting to brake or
slow the vehicle.
. Avoid making hard stops for
the first 322 km (200 miles)
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 Driving
Characteristics and Towing
Tips on page 9‑70 for the
trailer towing capabilities
of the vehicle and more
information.
Following break‐in, engine speed
and load can be gradually
increased.
