Break-in period
Moving parts need breaking-in time to adjust to each other. Please follow the instructions below in order to achieve the optimal service life and economy of operation for your vehicle.
Engine and differentialAlways obey all official speed limits.
Up to 1,200 miles/2,000 km
Drive at varying engine and road speeds, but do not exceed an engine speed of 4,500 rpm or a road speed of 100 mph/160 km/h.
Avoid full-throttle operation and use of the transmission's kickdown mode.
After driving 1,200 miles/2,000 kmEngine and vehicle speeds can be gradually increased.
TiresDue to technical factors associated with their manufacture, tires do not achieve their full traction potential until after an initial break-in period. Therefore, drive cautiously during the first 200 miles/300 km.
Brake systemBrakes require an initial break-in period of approx. 300 miles/500 km to achieve optimized contact and wear patterns between brake pads and rotors. Drive cautiously during this break-in period.
ClutchThe function of the clutch reaches its optimal level only after a distance driven of approx.
300 miles/500 km. During this break-in period, engage the clutch gently.
Following part replacementThe same break-in procedures should be observed if any of the components mentioned above have to be renewed in the course of the vehicle's operating life.
