Things to remember when drivingVehicle features and op‐tions
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and sys‐
tems. The respectively applicable country provi‐
sions must be observed when using the respec‐
tive features and systems.
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 78.
Information WARNING
Due to new parts and components, safety
and driver assistance systems can react with a
delay. There is risk of an accident. After instal‐
ling new parts or with a new vehicle, drive con‐
servatively and intervene early if necessary. Ob‐
serve the break-in procedures of the respective
parts and components. ◀
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.
Tires 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.
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 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.
