Break-in

A new vehicle must be broken in so that its moving parts and assemblies wear in against each other. Observe the instructions below. This will extend the service life of the vehicle and make its operation more economical.

Engine and Rear Axle Final Drive

Mileage up to 2,000 km:

vary engine speed and vehicle speed, but make sure that engine speed and vehicle speed do not exceed the following values:

► vehicles with gasoline engines: 4,500 rpm and 160 km/h;
► vehicles with diesel engines: 3,500 rpm and 150 km/h.

Observe the speed limits in effect in the country of travel.

When using the accelerator pedal, avoid full-load positions and Kick-Down.

When mileage exceeds 2000 km, engine speed and road speed can be gradually increased.

Vehicles with SMG transmission

Do not use the kickdown during the break-in period.

Tires

Due to the manufacturing technology, new tires achieve optimum road grip only after break-in. Therefore, drive with restraint during the first 300 km.

Brake System

The brake pads and discs optimally bed in to each other after approximately 500 km of driving.

Clutch

The clutch begins to work optimally after 500 km of driving. Until the break-in period is complete, engage the clutch as smoothly as possible.

After Replacing Components and Parts

These break-in rules must also be observed after replacing the above-mentioned assemblies and components.
