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:
- 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 (68mph).
- Between the first 1 000 km (600mi) 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.
- Do not tow a trailer during break-in. See Driving Characteristics and Towing
Tips for the trailer towing capabilities of your vehicle and more information.
Following break—in, engine speed and load can be gradually increased.
