Breaking-in period
General information
Moving parts need to be broken in to adjust to each other.
The following instructions will help achieve a long vehicle life and good economy.
Engine and differential
Always obey the official speed limit.
Up to 1,200 miles/2,000 km
Do not exceed the maximum engine and road speed:
- 4,500 rpm and 100 mph/160 km/h.
Avoid full load or kickdown under all circumstances.
From 1,200 miles/2,000 km
The engine and vehicle speed can gradually be increased.
Tires
Due to technical factors associated with their manufacture, tires do not achieve their full traction potential until after an initial breaking-in period.
Drive conservatively for the first 200 miles/300 km.
Brake system
Brakes require an initial break-in period of approx. 300 miles/500 km to achieve optimized contact and wear patterns between brake discs and brake pads. Drive moderately during this break-in period.
Clutch
The 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 replacement
The same breaking 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.
