New Vehicle Break-In

The vehicle does not
need an elaborate break-in. But it
will perform better in the long run
if you follow these guidelines:
Do not drive at any one
constant speed, fast or slow,
for the first 805 km (500 mi).
Do not make full-throttle
starts. Avoid downshifting to
brake or slow the vehicle.
During the first 1 000 km
(600 mi), avoid using more
than moderate acceleration
in lower gears and avoid
vehicle speeds above
110 km/h (68 mph).
Between the first 1 000 km
(600 mi) and 5 000 km
(3,000 mi), heavy
acceleration in lower gears
can be used. Vehicle speeds
above 110 km/h (68 mph)
should be limited to
five minutes per use.
Avoid making hard stops for
the first 322 km (200 mi) 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.
Driving and Operating
Do not tow a trailer during
break-in. See
trailer towing capabilities of
your vehicle and more
information.
Following break in, engine speed
and load can be gradually
increased.
