Hills
General information
Drive long or steep downhill gradients in the gear
that requires least braking effort. Otherwise, the
brake system may overheat and reduce braking
effect.
You can increase the engine's braking effect by
shifting down, going all the way to first gear, if
needed.
Safety information
Warning
Light but consistent pressure on the brake
pedal can lead to high temperatures, brakes
wearing out and possibly even brake system
failure. There is a risk of accident. Avoid placing
excessive stress on the brake system.
Warning
In idle state or with the engine switched off,
safety functions, for instance engine braking ef‐
fect, braking assistance and steering assis‐
tance, may not be available. There is a risk of
accident. Do not attempt to drive in idle state or
with the engine switched off.
Brake disc corrosion
Corrosion on the brake discs and contamination
on the brake pads are increased by the following
circumstances:
▷ Low mileage.
▷ Extended periods when the vehicle is not
used at all.
▷ Infrequent use of the brakes.
▷ Aggressive, acidic, or alkaline cleaning
agents.
Corrosion buildup on the brake discs will cause a
pulsating effect on the brakes in their response -
generally this cannot be corrected.

Condensation water under the
parked vehicle
When using the automatic climate control, con‐
densation water develops and collects under‐
neath the vehicle.
Ground clearance
NOTICE
If the ground clearance is insufficient, e.g.,
curbs or underground garage entrances, con‐
tact with vehicle parts, e.g., spoiler, and the un‐
derbody may occur. There is a risk of damage
to property, among other potential damage. En‐
sure that there is sufficient ground clearance
available.
M Driver's Package: driving in
the higher speed range
Warning
Damage to vehicle components can negatively
impact handling at high speeds. This includes,
