A pulsing of the brake pedal and hydraulic regu‐
lating sounds indicate that the Anti-lock Brake
System ABS is regulating.
In certain braking situations, the perforated brake
discs can cause functional noise. However, func‐
tional noises have no effect on the efficiency and
operational safety of the brakes.
Objects in the range of movement of
the pedals
WARNING
Objects in the driver's footwell can restrict the
pedal travel or block a pedal that has been
pressed. There is a danger of accidents. Stow
items in the vehicle so that they are secure and
cannot get into the driver's footwell. Only use
floor mats that are suitable for the vehicle and
can be securely fastened to the floor. Do not
use loose floor mats, and do not place several
floor mats on top of one another. Make sure
that there is sufficient space for the pedals. En‐
sure that floor mats are securely reattached af‐
ter having been removed, for example for
cleaning.
Wet roads
In damp weather, on gritted roads and in heavy
rain, apply the brakes lightly every few kilome‐
tres/miles.
Ensure that you do not obstruct other road users
when doing so.
The heat generated by braking dries the brake
discs and brake pads, and protects them against
corrosion.
This way, brake power is available immediately,
whenever it is needed.
Downhill gradients
General
When driving on long or steep downhill
stretches, use the gear in which the least braking
is required. Otherwise the brake system can
overheat and braking effect is reduced.
Engine braking effect can be additionally in‐
creased by manually shifting down, even into first
gear, if applicable.
Safety notes
WARNING
Even slight continuous pressure on the brake
pedal can cause overheating, brake pad wear or
even brake system failure. There is a danger of
accidents. Avoid excessive loads on the brake.
WARNING
When idling or with the engine switched off,
safety-relevant functions are restricted or no
longer available, for example the braking effect
of the engine or power assistance for the brak‐
ing force and steering. There is a danger of ac‐
cidents. Do not drive at idle speed or with the
engine switched off.
Corrosion of the brake disc
Corrosion of the brake discs and contamination
of the brake pads increase in the following cir‐
cumstances:
▷ Low mileage.
▷ Extended periods when the vehicle is not
used.
▷ Infrequent use of the brakes.
▷ Aggressive, acidic or alkaline cleaning agents.
Should corrosion form on the brake discs, the
brakes will tend to respond with a judder effect
that generally cannot be eliminated.
Condensation when vehicle is
parked
When the automatic air conditioning is in opera‐
tion, condensation develops which exits under‐
neath the vehicle.
