¢ page 189, Working in the engine com­
portment
before open ing the hood and
check ing the brake fluid level.
- If the brake system ind icator light does not
turn off or it turns on while dr iv ing, the
brake fluid level in the reservoir is too low,
and this increases the risk of an acc ident.
Stop the vehicle and do not continue dr iv­

be malfunct ion ing . Funct ions that stabilize
the vehicle are no longer available. This
could cause the vehicle to swerve, which in­
creases the risk that the vehicle will slide. Do not cont inue driving. See an autho rized

" N .... 0 0 \,;J ' Wear Brake pad
wear depends largely on the way the
vehicle is driven and on operating conditions.
This is especially true if you are driving frequently
in the city and on curves or with a sporty driving
style.
Operating noise
Noises may occur when braking depending on the
speed, braking force and outside conditions such
as temperature and humidity.
Effect of water and road salt
In certain situations, for example after driving
through water, in heavy ra in, after overnight 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 with a few careful brake applica ­
tions.
At higher speeds and with the windshie ld wipers
turned on, the brake pads press against the brake rotors for a short amount of time. This 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 effect 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
f ir st when the brakes are applied.
Corrosion
Leaving the vehicle parked for long periods of
time, low mileage and avo iding heavy brak ing
can contribute to corrosion on the brake rotors
and to d irty brake pads .
If you usually avoid heavy braking or if there is
corros ion present, occasional heavy braking at
high speeds is recommended to clean the brake
rotors and
pads¢ &..
Brake system malfunction
If you notice that the brake pedal travel has sud­
denly
increased, then a brake circuit in the dual­
circu it brake system may have malfunct ioned.
Drive to an authorized Aud i dealer or authorized
Intelligent Technology
Audi Service Facility immediately to have the
problem corrected. On the way there, drive with
reduced speed and keep in mind that you will
need a longer distance to stop and you will need
to press the brake peda l harder.
Low brake fluid level
When the brake fluid level is low, malfunctions in
the brake system may occur . The brake fluid level
is e lectronically monitored.
Brake booster
T he brake booster amplifies the press ure you ap­
ply to the brake pedal. It on ly works w hen the en­
gine is running.
A WARNING
-
-Only apply the brakes for the purpose of
cleaning the brake system when road and
traffic cond itions permit. You must not en­
danger other road users. This increases the
risk of an accident .
- Never let the vehicle roll while the engine is
stopped because this increases the risk of an
accident .
- New brake pads do not ach ieve the ir full
braking effect dur ing the first 250 m i
(400 km). They must be "broken in" first .
However, you can compensate fo r the
slightly reduced braking force by pressing
firmly on the brake pedal. Avoid heavy b rak­
ing during the break -in period.
- Ce rtain weather and operating conditions
such as driving through water, dr iv ing in
heavy rain or driving after washing your ve ­
hicle can impair the effectiveness of the
brakes. In the winter, ice may build up on
the brake pads, rotors and drums. Check
these components by braking carefully. Ap­
plying the brakes carefully several times
dries the brakes and removes ice build-up .
- The efficiency of the brakes can also be im­
pa ired by dr iv ing for long stretches on roads
covered with salt without using the brakes.
You can remove salt deposits from the
brake rotors and pads by carefully applying
the brakes several times.

A WARNING
-Turn the engine off.
- Sw itch the ignition off.
- Set the parking brake.
- Select the "P" selector lever position .
- Let the eng ine cool down .
- Never open the hood when there is steam or
coolant escaping from the engine compart­ ment, because there is a risk that you could
be burned . Wait unt il no steam or coolant is
escaping.
- Keep children away from the eng ine com­
partment .
- Never sp ill fluids on a hot engine. These flu­
ids (such as the freeze protection contained in the coolant) can catch fire.
- Avoid short c ircuits in the electrical system .
- When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which increases the ris k of personal injury .
- Never open the cap on the coolant expan­
sion tank when the engine is warm . The
coo ling system is under pressure.
-To protect your face, hands, and arms from hot steam or coolant, cover the cap with a
large cloth when opening .
- Do not remove the eng ine cover under any
circumstances . This increases the risk of
bu rns .
- If tests need to be performed with the en­
g ine runn ing, there is add it iona l danger due
to mov ing components (such as the ribbed

belt, alternator and radiator fan) and from
the high-voltage ignition system.
- Do not under any circumstances give gas in­
advertently (for example, by hand from the
engine compartment) if the vehicle is sta­
tionary but the engine is running and a gear
is engaged. Otherwise, the vehicle will start
to move immediately and this could result
in an accident.
- Pay attention to the following warnings list­
ed when work on the fuel system or on the
electrical equipment is required.
- Do not smoke.
- Never work near open flames.
- Always have a working fire extinguisher
nearby.
- All work on the battery or electrical system
in your vehicle can result in injuries, chemi­
cal burns, accidents or burns. Because of
this, all work must be performed
only by an
authorized Audi dealer or authorized Audi
Service Facility.
- To reduce the risk of electric shock and in­
jury, never touch the following components when the engine is running or is being start­
ed:
- Ignition cable
- Other components in the electronic high-
voltage ignition system
- If you must check or perform work on the
engine while it is running:
- Set the parking brake and place the selec­ tor lever in the P (park) position first.
- Always proceed with extreme caution so that clothing, jewelry or long hair do not
become caught in the radiator fan, fan
belt or other moving components or do
not come into contact with hot compo­
nents. Tie back long hair before beginning
work and do not wear clothing that can
hang down into the engine.
- Limit your exposure to exhaust and chemi­
cals to as short a time as
possible~ &..
