BMW 3: Breaking-in period
General information
Moving parts need to begin working together smoothly.
The following instructions will help you to achieve a long vehicle life and good efficiency.
During break-in, do not use the Launch Control.
Safety information
Warning Due to new parts and components, safety and driver assistance systems can react with a delay.
There is a risk of accident. After installing new parts or with a new vehicle, drive conservatively and intervene early if necessary. Observe the break-in procedures of the respective parts and components.
Engine, transmission, and axle drive
Up to 1,200 miles/2,000 km
