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 the vehicle 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.
