Starting and Operating
New Vehicle Break-In
Caution
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
800 km (500 mi). Do not make
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.
Following break-in, engine speed
and load can be gradually
increased.
On new vehicles, the various
mechanical and electrical systems
experience a
“
break-in
”
period during
the first 6,400 km (4,000 miles) 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. See
