Driving
– the brake pressure applied by pressing the
brake pedal is higher than the brake pressure
initiated by the system, or
may occur temporarily and haptic feedback may
be felt on the brake pedal.
Braking effect
– the ESC, the brake system or the vehicle's elec-
trical system are not fully functional.
To ensure an optimum braking effect, the brake
pads are applied to the brake discs briefly at high
speeds when the windscreen wipers are on.
WARNING
– When applying the brakes to clean off de-
posits on the pads and discs, select a clear,
dry road. Be sure not to endanger other road
users; do not risk an accident.
If the brake system is wet, e.g. after driving in
heavy rain, the braking effect may be delayed.
Further causes of a temporary increase in brake
response time include:
– All brake repairs must be carried out by a
qualified workshop working to the specifica-
tions of the Audi factory – risk of injury! Im-
proper repairs can also impair the function
of the system.
– Wet conditions
– Low temperatures, ice and snow
– Salted roads
– Dirty brake pads
– Never let the vehicle coast with the power
unit switched off (this can cause accidents).
– If you wish to equip the vehicle with accesso-
ries such as a front spoiler or wheel covers,
it is important that the flow of air to the
brakes is not obstructed; otherwise the
brakes can overheat – risk of accident!
Corrosion
Corrosion can form on the brake discs if the car is
used infrequently, or if you only drive low mile-
ages. In this case, you can clean the brake discs
by braking firmly a few times from a moderately
high speed ð
.
Brake pads
CAUTION
New brake pads do not give full braking effect for
the first 400 km, they must first be “bedded in”.
However, you can compensate for the slightly re-
duced braking effect by applying more pressure
on the brake pedal. Avoid placing a heavy load on
the brakes during the running-in period.
– Never let the brakes “drag” by leaving your
foot on the pedal when you do not really in-
tend to brake. This can cause the brakes to
overheat, resulting in longer stopping dis-
tances and greater wear.
– Please observe the important safety warn-
ings on driving on gradients ðpage 110.
This is especially important when towing a
trailer or caravan.
The rate of wear on the brake pads depends a
great deal on how you drive and the conditions in
which the vehicle is operated. For example, the
rate of wear will increase if the vehicle is used
frequently in city traffic, for short distances, or
for hard driving with abrupt starts and stops.
Driver messages about the brake system
The following driver messages may appear, de-
pending on the equipment installed in your vehi-
cle:
Multicollision brake assist system
The multicollision brake assist system can help to
reduce the risk of skidding and further collisions
during an accident. If the airbag control unit de-
tects that a collision has taken place, the ESC sys-
tem applies the brakes.
Brakes: fault. Safely stop vehicle
A malfunction has occurred in the brake system.
If and also light up, this means that the
ABS, ESC and brake force distribution systems
have failed. You need to apply much more force
to operate the brakes if the brake servo fails.
The vehicle will not be braked automatically if:
– you apply the accelerator, or
