BREAKING-IN YOUR VEHICLE
Your vehicle does not need an extensive break-in. Try not to drive
continuously at the same speed for the first 1000 miles (1600 km) of
new vehicle operation. Vary your speed frequently in order to give the
moving parts a chance to break in.
Do not add friction modifier compounds or special break-in oils since
these additives may prevent piston ring seating.
