sudden, hard brake applications.
- Canada models: If the brake warning
light ., the

qua lified workshop. Drive s low ly and
avoid sudden, hard brake applications .
- I f the b rake w arning/ind icator light does
not go out after a few seconds and the
parking brake released, or lights up wh ile
you are driving, the fluid level in the brake fluid reservoir is too low. If you be­
lieve that it is safe to do so, proceed im­
mediately at low speed to the nearest

freezing conditions ice) on the brake pads. A
few careful brake applications should dry off
the brake pads or remove any ice coatings.
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered
road and the brakes are not used . Here too
,
you should clean off accumulated salt coating
from brake discs and pads with a few careful
applications of the brake
Q & .
Corrosion
There may be a tendency for dirt to build up
on the brake pads and corrosion to form on
the discs if the car is not driven regularly or
only for short trips with little use of the brakes.
If the brakes are not used frequently, or if cor­
rosion has formed on the discs, it is advisable
to clean off the pads and discs by braking
f irmly a few times from a moderately high
speed
Q & .
Faults in the brake system
If you should notice a sudden increase in
brake pedal travel, then one of the two brake
circuits may have failed
Q & .
Low brake fluid level
Malfunctions can occur in the brake system if
the brake fluid level is too low. The brake fluid
level is monitored electronically.
Brake booster
The brake booster works with vacuum pres­
sure which is created only when the engine is
running
Q & .
Brake lining wear status
Brake lining wear may be checked by visual in­
spection of the condition of the brake pads
through the openings in the wheel. If neces­
sary, the wheel may be removed for this in­
spection
Q page 258, Changing a wheel.
WARNING
- You should perform braking maneuvers
for the purpose of cleaning the brake system only if road conditions permit.
Other road users must not be put at risk -
you may cause an accident!
- Before descending a steep grade, reduce
speed and shift transmission into a lower
gear or lower driving range. Do not ride
the brakes or hold the pedal down too
long or too often . This could cause the
brakes to get hot and diminish braking
efficiency.
- Do not "ride the brakes" by resting your
foot on the pedal when you do not intend
to brake. This may cause the brakes to
overheat, premature wear and increased
stopping distance.
- Under certain climatic and operating
conditions such as passing through wa­
ter, driving in heavy rain or after washing
the vehicle, the effectiveness of the brakes can be reduced. In winter, ice can
accumulate on the brake pads, linings,
discs and drums. Carefully apply brakes
for a test. Brakes will dry and ice coat­
ings will be cleaned off after a few care­
ful brake applications.
- Driving for an extended period of time on
salt-covered roads without using your brakes can also affect braking efficiency.
Clean off accumulated salt coating from
brake discs and pads with a few careful
brake applications.
- If you damage the front spoiler, or if you
install a different spoiler, be sure the air
flow to the front brakes is not obstruct­
ed. Otherwise the brake system could
overheat reducing the effectiveness of
the entire brake system.
- Failure of one brake circuit will impair
the braking capability resulting in an in­
creased stopping distance. Avoid driving
the vehicle and have it towed to the near­
est Audi dealer or qualified workshop.
- Never let the vehicle roll to a stop with
the engine shut off.
- If the brake booster is not working, for
example when towing your vehicle, or
because the brake booster has somehow
been damaged, the brake pedal must be
