Fa ults in the brake system
If yo u should notice a sudden increase i n brake
pedal travel, then one of the two brake circuits
may have failed
¢ .&. .
Low brake fluid level
Malf unct ions can occur in the bra ke system if the
b rake fl uid leve l is too low. The brake fluid level
i s monitored e lectronica lly .
Bra ke booste r
The brake booster increases the pressure that
you generate with the brake pedal.
It works on ly
when the engine is run ning
.¢ .&.
Bra ke lining we ar status
Brake lining wear may be checked by visual in­
spection of the condition of the brake pads
through the open ings in the wheel. If necessary,
the wheel may be removed for this inspection
¢ page 228, Replacing wheels.
A WARNING
- New bra ke pads don't have the best stop­
ping power and must be "bro ken- in" dur ing
the init ia l 250 m iles (400 kilometers). Yo u
can compensate for th is by press ing the
brake pedal more firmly. This a lso applies
later when new pads are installed.
- Yo u should perfo rm braking maneuvers for
the p urpose of clean ing 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 t ransm iss ion into a lower
gear or lowe r driving range. Do not ride the
brakes or hold the pedal down too long or
too often. This could ca use the brakes to get
hot and diminish brak ing efficie ncy.
- Do not "r ide t he b rakes" by resting your foot
on the pe dal when yo u do not inten d to
bra ke. This may cause the bra kes to over­
heat, premat ure wear and increased stop ­
ping distance.
- Under certa in climatic and operating condi­
tio ns such as passing thro ugh water, driving
in heavy rain or after washing the vehicle,

the effectiveness o f the brakes can be re­
duced. In winter, ice can accum ulate on the
brake pads, lin ings, d iscs and drums . Care­
fu lly apply brakes for a test . Brakes will dry
and ice coat ings will be cleaned off after a
few ca refu l brake applications .
- Driving for an extended period of t ime on
salt-covered roads without usi ng your
b rakes can also affect braking eff iciency.
Clea n off acc umul ated salt coat ing from
b rake discs an d pa ds w ith a few careful
b rake appli cat ions .
- I f you d amage the front spoile r, or if you in­
s t all a different spoiler, be s ure the a ir flow
to the front brakes is not obstruc ted. Other­
wise the brake system could overheat reduc­ ing the effectiveness of t he ent ire bra ke sys­
tem.
- Fai lure of one brake circuit w ill impa ir the
braking capability resulting in an increased
stopping distance . Avoid driving the vehicle
and have it towed to the nearest authorized
Aud i dealer 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 pedal must be pressed cons iderab ly
ha rder to make up fo r the lack of booste r
assis tance .
Electro-mechanical
power assist, dynamic

The electro-mechanical power assist helps the
driver when steering.
Power steer ing adapts electronically based on
the vehicle speed.
Indicator lights and messages
