- Read and follow the warnings in
¢ page 235, Working in the engine com­
partment
before opening the hood and
checking the brake fluid level.
- If the brake system indicator light does not
turn off or it turns on while driving, the
brake fluid level in the reservoir is too low,
and this increases the risk of an accident.
Stop the vehicle and do not continue driv­
ing. See an authorized Audi dealer or au­
thorized Audi Service Facility for assistance.
- If the brake system indicator light turns on
together with the ABS and ESC indicator
lights, the ABS/ESC regulating function may
be malfunctioning. Functions that stabilize

Intelligent Technology
Operating nois e
Noises may occur when br aking depend ing on the
speed, b raking force and outside cond itions such
as tempe rature and humidity.
Effect of water and road salt
I n ce rtain s ituations, for example after driving
through wa ter, in heavy ra in, afte r ove rnig ht con ­
densat ion or after washing your car, the braking
effect can be reduced by moisture or ice on the
brake rotors and brake pads. The brakes must be
"dried" first w ith a few careful brake applica­
tions.
At highe r speeds and with the windshie ld wipers
turned on, the brake pads press against the brake rotors for a short amount of time . Th is action,
which is not felt by the driver, happens at regular
intervals and ensures a better reaction time for
the brakes in wet weather .
The braking eff ect can also be reduced if you are
driving on salted roads and you do not apply the
brakes for long periods of time. The layer of salt
on the brake rotors and pads must be worn off
first when the brakes are applied .
Corrosion
Leaving the vehicle parked for long periods of
time, low mi leage and avoiding heavy braking
can contribute to corrosion on the brake rotors
and to dirty brake pads .
If you usually avoid heavy braking or if there is
corros ion present, occasional heavy braking at
h igh speeds is recommended to clean the brake
rotors and pads
¢ ,& .
Brake system malfunct ion
if you notice that the brake pedal travel has sud­
denly increased, then a brake c ircuit in the dual­
circu it brake system may have malfunct ioned.
Drive to an authorized Aud i dea ler or aut horized
Aud i Serv ice Facility immediately to have t he
p roblem co rrected . On the way there, drive with
reduced speed and keep in mi nd that you w ill
need a longer d istance to s top and you w ill need
to p ress the brake pedal har der.

Low brake fluid level
When the brake fluid level is low, m alfunc tions in
the b rake system may occur . The brake fluid leve l
i s e lectronically monitored .
Brake booster
The brake booster ampl ifies the press ure you ap­
ply to the brake pedal.
_&. WARNING
- New brake pads do no t achieve the ir full
braking effect during the first 2 50 m i
-
(400 km). They m ust be "b roken in" first .
However, you can compensate fo r the
slightly reduced braking force by pressing
firm ly on the brake pedal. Avoid heavy brak­
ing during the break-in period .
- On ly app ly the bra kes for the purpose of
cleaning the brake system when road and
traffic conditions permit. You must not en­ danger other road users . This increases the
ris k of an accident.
- On steep slopes, reduce the speed and se­
lect a lower gear o r lower selector leve r po·
si tion. D rive as little as possible while press­
ing the bra ke pedal and avoi d pu tting your
left foot on the brake pedal while dr iv ing.
This could cause the bra kes to overhea t and
impair the efficiency of the b rakes.
- Do not let the bra kes "grind" by always
keep ing your foot on the bra ke pe dal. This
can cause the brakes to overheat, inc rease
wear and increase braking distance unneces­
sarily .
- Ce rtain weather and operating conditions
such as d riving through water, dr iv ing in
heavy rain or driv ing after wash ing your ve­
hicle can impai r the effective ness of the
brakes . In t he win ter, ice may build up o n
the bra ke pa ds, rotors and dr ums. Check
t hese components by b raking carefully. Ap ­
plyi ng the brakes carefully seve ral times
dries the brakes and removes ice build-up .
- The efficiency o f th e brakes can also be im­
p air ed by dr iv ing for long s tretches on roads
covered with sa lt wi thout using the bra kes .

and have the cooling system inspected. If the
cooling system is not leaking, a loss can come
from the coolant boiling through overheating
and being pushed out of the cooling system.
A WARNING
The cooling system is pressurized and can be­
come very hot. To reduce the r isk of burns
from hot coolant:
- Do not open the coolant expansion tank cap when the eng ine is hot. This increases the
risk of burns.
- Stop the engine and allow it to cool.
- Protect your face, hands and arms from es-
caping coolant and steam by covering the
coolant tank cap with a large, thick cloth.
- Turn the coolant tank cap counterclockwise
slowly and keep light pressure o n the cap.
- To reduce the risk of burns, do not allow any
antifreeze or coolant to drip onto the ex­ haust system or hot eng ine components .
T he ethylene glycol in eng ine coolant can
catch fire under certa in circumstances.
- The coo lant add itive and the coolant can be
dange rous to your health. For this reason,
keep the coolan t in the origina l container
and away from children. There is a risk of
poisoning.
- When working in the engine compartmen t,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of inj ury.
(D Note
Do not add coolant if the exp ansion tank is
empty . Air could enter the cooling system and
damage the engine . If this is the case, do not
continue driving. See an authorized Audi deal­
er or authorized Audi Service Facility for assis­
tance.
