Faults in the brake system
If you should notice a sudden increase in
brake peda l travel, t hen one of the two bra ke
circuits may have failed ¢ .&..
Low brake flu id level
Malfunct ions can occur in the brake system if
the brake fluid level is too low. The brake fluid
leve l is monitored electronically .
Brake booster
The brake booster increases the pressure that
you generate with the brake pedal. It only op-
erates while the eng ine is running ¢ ,&..
Brake lining we ar st atu s
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 ¢

A WARNING
- You should perfo rm bra king maneuve rs
for the purpose of clean ing the b rake
system on ly if road condit ions 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 dimin ish 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 climat ic and operating
condit ions such as passing through wa-
ter, driving in heavy ra in or after wash ing
the vehicle, the effect iveness of t he
brakes can be reduced . In winter, ice can
accumu late on the brake pads, linings,
discs and drums. Carefully app ly brakes
for a test. Brakes will dry and ice coat-
ings will be cleaned off after a few care-
ful brake applicat ions .
- 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 ca reful
brake applications.
- If you damage the front spoiler, or if you
install a diffe rent spoiler, be sure the a ir
f low t o the front brakes is not obs t ruct-
ed . Otherwise the brake system could
overheat reducing the effectiveness of
the entire brake system .
- Failure of one brake circuit will impai r
the braking capability resulting in an in-
creased stopping distance . Avoid driving
the vehicle and have it towed to the near-
est authorized Audi dea ler or qualified
workshop .
- Never let the vehicle roll to a stop with
the engine shut off.
- If the brake booster is not working, the
brake peda l must be pressed cons idera-
bly harder to make up for the lack of
booster assistance.
Servotronic - advanced
power steering system
The power steering systems uses the power of
the running engine to allow precise steering
with Little effort.
The advanced Servotronic power steer ing sys-
tem senses the road speed and electronica lly
adjusts power assistance to provide comforta-
ble and safe steering response exactly match-
ed to the vehicle speed.
Power st eer ing will not work if the engine is
off. As a result, the steering wheel will be hard
to turn.
The powe r steering fluid level is checked d ur-
ing the sched uled maintenance services . ..,.
