Things to remember when driving

Vehicle features and options

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

systems. The respectively applicable country

provisions must be observed when using the

respective 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 Con‐

trol, refer to page 75.

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 pe‐

riod.

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.

General driving notes

Closing the trunk lid

Drive with the trunk lid closed

Only drive with the tailgate closed; other‐

wise, in the event of an accident or braking and

evasive maneuvers, passengers and other traf‐

fic may be injured, and the vehicle may be

damaged. In addition, exhaust fumes may en‐

ter the vehicle interior.◀

If driving with the tailgate open cannot be

avoided:

▷ Close all windows and the glass sunroof.

▷ Greatly increase the air flow from the vents.

▷ Drive moderately.

Hot exhaust system

High temperatures are generated in the

exhaust system.
