Breaking-in period General information
Moving parts need time to adjust to one an‐ other (break-in time).
The following instructions will help accomplish a long vehicle life and good efficiency.
During break-in, do not use the Launch Control, refer to page 61.
Engine, transmission, and axle drive
Up to 1,200 miles/2,000 km
Do not exceed the maximum engine and road speed:
▷ For gasoline engine 4,500 rpm and 100 mph/160 km/h.
Avoid full load or kickdown under all circum‐ stances.
From 1,200 miles/2,000 km
The engine and vehicle speed can gradually be increased.
Things to remember when driving
Things to remember when driving
Tire traction is not optimal due to manufactur‐ ing circumstances when tires are brand-new; they achieve their full traction potential after a break-in time.
Drive conservatively for the first 200 miles/300 km.
Brake system
Brakes require an initial break-in period of ap‐ prox. 300 miles/500 km to achieve optimal per‐ formance between brake discs and brake pads. Drive moderately during this break-in period.
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 break-in procedures should be ob‐ served if any of the components above-men‐ tioned have to be renewed in the course of the vehicle's operating life.
