full-throttle starts. Avoid
downshifting to brake or
slow the vehicle.
.
Avoid making hard stops
for the first 300 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.
.
Do not tow a trailer during
break-in. See Trailer
Towing
351 for the
trailer towing capabilities
of the vehicle and more
information.
Following break-in, engine
speed and load can be
gradually increased.

mechanical and electrical
systems experience a

break-in
”
period during the
first 6 400 km (4,000 mi) of
routine driving. As the vehicle
is driven, the mechanical
systems adjust to provide
optimal fuel economy and
transmission shift
performance.
Electrical systems will adapt
and calibrate during the
break-in period. A one-time
occurrence of clicks and
similar vehicle noises is normal
during this process.
Normal driving charges the
vehicle
’
s battery to achieve
the best operation of the
vehicle, including fuel economy
and the Stop/Start System.
