page 258 . See
your authorized A udi dea le r as soon as poss ible .
& WARNING
• If the .. (USA models )/ ...,. (Canada models ) wa rning light
does not go out , or if it comes on while driving, the ABS system is
not working properly. The vehicle can then be stopped only with
the standard brakes (without ABS ). You will not have the p rotec­
tion ABS provides. Contact your authorized Audi dealer a s soon as
pos sible.
• USA models : If the BRAKE warning light and the M, warning
light come on together, the rear wheels could lock up fir st under
hard braking. Rea r wheel lock-up can cause loss of vehicle cont rol
and an accident . Have your vehicle repaired immediately by your
autho rized Audi dealer or a qualified work shop. Dri ve slowly and
avoid sudden, hard brake applications.
• Canada models: If the brake warning light 0 and the ABS
warning light come on together, the rear wheels could lock up
first under hard braking. Rear wheel lock -up can cause loss of
vehicle control and an accident . Have your vehicle repaired imme­
diately by you r authorized Audi dealer or a qualified wo rkshop.
Drive slowly and avoid sudden , hard brake applications .•

& WARNING
• USA models : If the BRAKE warning light and the I .. S warning
light come on together, the rear wheels could lock up first under
hard braking . Rear wheel lock-up can cause lo ss of vehicle control
and an accident . Have your vehicle repa ired immediately by your

& WARNING (continued)
first under hard braking. Rear wheel lock-up can cause loss of
vehicle control and an accident. Have your vehicle repaired imme­ diately by your authorized Audi dealer or a qualified workshop.
Drive slowly and avoid sudden, hard brake applications.
• If the brake warning/indicator light does not go out after a few
seconds and the parking brake released, or lights up while you are
driving, the fluid level in the brake fluid reservoir is too low. If you
believe that it is safe to do so, proceed immediately at low speed
to the nearest authorized Audi dealer or qualified repair facility
and have the brake system inspected .
• Always keep in mind that after several brake applications, you
will need greater pressure on the brake pedal to stop your vehicle .
Do not rely on strained brakes to respond with maximum stopping
power in critical situations. You must allow for increased braking
distances. The extra distance used up by fading brakes could lead
to an accident. •

Engine cooling system malfunction _
t_
A malfunction in the engine cooling system must be
repaired as soon as possible.
When the -L symbol in the display blinks, then either the
engine coolant
temperature is too high, or the coolant level
is too low. An additional driver message can also be displayed
by pressing the [CHECK] button:
Switch off engine and check coolant level
- Pull off the road .
- Stop the vehicle.
- Turn off the engine.

-Continue driving only after the engine coolant
warning/indicator light goes out.
- Contact your authorized Audi dealer for assistance if
necessary.
If the engine coolant level is correct, then the radiator fan may be the
cause of the malfunction.
If the O warning symbol (alternator malfunction) also lights up on
the instrument panel:::::,
page 34, then the fan belt may be damaged .
& WARNING
• If your vehicle should break down for mechanical or other
reasons, park at a safe distance from moving traffic, turn off the

The ASR works in conjunction with the ABS. If a malfunction should
occur in the ABS, the ASR w ill also be out of action.
& WARNING
The increased safety afforded by ASR does not mean that you can
take safety risks. Always adapt your driving style to the road
conditions and traffic situation.
[ i] Tips
To ensure that the ASR works properly, all four whee ls must be fitted
with ident ical tires. Any differences in rolling radius of the tires can
cause the system to reduce engine power when th is is not desired.

Braking
General information
What affects braking efficiency?
Operating conditions and driving habits
The brakes on today's automobiles are still subject to wear,
depending large ly on operating conditions and driving habits=>& .
On vehicles that are either driven mostly in stop -and -go city traffic or
are driven hard, the brake pads should be checked by your authorized
Audi dealer more often than specified in the
Warranty & Mainte­
nance booklet.
Failure to have your brake pads inspected can result
in reduced brake pe rformance .
On steep slopes, you should use the brak ing effect of the engine . This
way, you prevent unnecessary wear on the brake system. If you must
use your brakes, do not hold the brakes down continuously. Pump the
brakes at intervals.
Noises may occur when braking depending on the speed , braking
force and outside conditions such as temperature and humidity.
Safety first
Moisture or road salt
If you are driving faster than 31 mph (SO km/h) and the windshield
wipers are on, the brake pads wi ll briefly touch the brake discs in
regular interva ls so as to improve reaction time when braking on wet
surfaces . You, the driver, will not not ice anything.
Under certain cond itions, for example, when driving through wa ter or
very heavy rain, or even after washing yo ur vehicle , the braking effect
can be reduced due to moisture (or in free zing conditions ice) on the
brake pads. A few careful brake applications should dry off the brake
pads or remove any ice coatings .
The effect iveness of the brakes can be reduced when the vehicle is
dr iven on a sa lt-covered road and the brakes are not used. Here too,
you should clean off accumu lated salt coating from brake discs and
pads with a few careful applications of the brake=> & -
Corrosion
There may be a tendency for dirt to build up o n the brake pads and
corrosion to form on the dis cs if the car is no t driven regularly or only
for short trips with little use of the brakes.
If the brakes are not used frequently, or if corrosion has formed on
the discs, it is advisable to clean off the pads and discs by braking
firmly a few times from a moderately high speed=> &.
Faults in the brake system
If you should notice a sudden increase in brake pedal travel, then one
o f the two brake circuits may have failed==>& .
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 e lectron ically .
Brake lining wear status
Brake lining wear may be checked by visual inspection of the condi­
tion of the brake pads through the openings in the wheel. If neces­
sary, the wheel may be removed for this inspection =>

"Changing a wheel". ._.
