Introduction
VEHICLE BREAK-IN PROCESS
No special break-in period is needed. By
following a few simple precautions for
the first 1,000 km (600 miles) you may
add to the performance, economy and
life of your vehicle.
• Do not race the engine.
• While driving, keep your engine speed
(rpm, or revolutions per minute)
within 3,000 rpm.
• Do not maintain a single speed for
long periods of time, either fast or
slow. Varying engine speed is needed
to properly break-in the engine.
• Avoid hard stops, except in emergen‐
cies, to allow the brakes to seat
properly.
