Instruments and warning/indicator lights 15
(USA models): If the warning light 1111 and
the warning light
EiJ appear together, imme­
diately contact your authorized Audi dealer or
qualified workshop to have all brake pads in­
spected
¢ page 20 .
When t he light comes on, an audible warning
signal is also given.
A WARNING
-Always observe the warnings in
¢ page 226, Engine compartment, be­
fore opening the hood and checking the
brake fluid .
- Driving with low brake fluid is a safety
hazard. Stop the car and get professional
assistance.
- USA models: Ifthe llll warning light,
the
G1 warning light and the firlilJ warn­
ing 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 immediately
by your authorized Audi dealer or a quali­
fied workshop. Drive slowly and avoid sudden, hard brake applications.
- Canada models: If the brake warning
light ., the
DJ warning light and the
ABS warning light
BJ 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 acci­
dent . Have your vehicle repaired immedi­
ately 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 is 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 in­ spected. -
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.
PARK/( ®) Electromechanical parking
brake
The warning/indicator light monitors the
electromechanical parking brake.
If the indicator light - (USA models)/ .
(Canada models) turns on, the parking brake
was set. If the parking brake is set when the
ignition is off, the indicator light turns off af­
ter about 20 seconds.
Th e warning/indicator light will go out when
the parking brake is released.
- (USA models) ,. (Canada models)
Caution: Vehicle parked too steep
If the indicator light blinks and the message
appears, there is not enough braking power to
ke ep the vehicle from rolling . The brakes have
overheated. The vehicle could roll away even
on a small incline .
Press brake pedal to release parking brake
To release the parking brake, press the brake
pedal and press the button
@ii or start driving
with starting assist at the same time
¢page 86 .
Please release parking brake
To release the parking brake manually , press
the brake pedal and press the button~ at the
same time. The parking brake only releases
automat ica lly if the driver's safety belt is fas­
tened .
ES Parking brake!
If the ES indicator light turns on and this
message appears, there is a parking brake
malfunction. Drive to your authorized Audi

Effect of w ate r and ro ad sa lt
In certain situa tions, for example after driving
through water, in heavy rain, after overnight
condensation 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 wit h a few careful
brake applications.
At higher speeds and with the windshield wip ­
ers turned on, the brake pads press against
the brake rotors for a short amount of time.
This occurs at regular intervals w ithout the
driver noticing and provides for better brake response time under wet condit ions.
The effectiveness of the brakes can be reduced
when the vehicle is dr iven o n a salt-covered
road and the brakes are not used . Likewise,
you clean
off accumulated sa lt coating from
brake discs and pads with a few caut ious ap­
p lications of the brake¢&. -
Due to their surface characteristics, ceram ic
brake roto rs* absorb mo isture in such condi­
tions. This can cause a temporary reduction in
b rak ing fo rce compared to d ry brakes. You can
compensate for this by pressing the brake pedal harder .
Corrosion
There may be a tendency for dirt to build up
on the brake pads and corrosion to form on
the discs if the car is not dr iven regularly or
on ly for short t rips with little use of the
brakes.
I f t he b rakes are not used frequently, or if co r­
rosion has formed on the dis cs, it is advisable
to clean
off the pads and discs by brak ing
firm ly a few times from a moderately high
speed ¢.&. .
Faults in the brake system
If you should notice a sudden increase in
b rake peda l travel, then o ne of the two bra ke
circuits may have failed~ .&..
Int ellig ent technolog y 201
Low br ake fluid level
Malfunctions can occu r in the bra ke system if
the b rake fluid level is too low. The brake fluid
level is monitored electronica lly.
Brake lining wear status
B rake lining wear may be checked by visual in­
spe ct ion of the condition of the brake pads
through the open ings in the wheel. If neces­
sary, the whee l may be removed for this in­
spection
r=;, page 2 7 3, Changing a wheel.
_& WARNING
-You should perform braking maneuvers
for the purpose of cleaning the brake
system only if road conditions permit.
Other road users must not be put at risk -
you may cause an accident!
- Before descend ing a steep grade, reduce
speed and sh ift transmission into a lower
gear or lower dr iving range . Do not ride
the brakes or hold t he pedal down too
long o r too often. Th is could cause the
brakes to get hot and diminish braking
efficiency .
- Do not "ride the brakes" by rest ing you r
foo t on the pedal when you do not intend
to b rake . This may cause the brakes to
overheat, premature wear and increased
stopping distance.
- Under certain climatic and operating
conditions such as passing thro ugh wa­
ter, dr iv ing in heavy rain or after washing
the vehicle, the effectiveness of the brakes can be reduced. In winter, ice can
accumu late on the brake pads, lin ings,
discs and drums . Carefully app ly brakes
for a test. Brakes w ill dry and ice coat­
ings w ill be cleaned
off after a few care­
fu l brake applicat ions.
- Driving for an extended period of time on
salt- cove red roads without using your
brakes can a lso affect braking efficiency .
Clean
off accum ulated salt coating from
brake discs and pads with a few careful
brake applications.

202 Intellig ent technol ogy
- If you damage the fro nt spoiler, or if you
install a different spoiler, be sure the air
flow to the front brakes is not obstruct­ ed . Otherwise the brake system could
overheat reducing the effectiveness of
the ent ire brake system .
- Failure of one brake c ircuit will impair
the braking capability resulting in an in­ creased stopp ing distance. Avoid driv ing
the vehicle and have it towed to the near­ est Aud i dea ler or qualified workshop .
Brake booster
The brake booster adds extra braking power .
The brake booster works with vacuum pres­
sure which is created only when the engine is
running ¢& .
& WARNING
-Never let the vehicle ro ll to a stop w ith
the engine shut off.
- If the brake booster is not work ing, for
example when towing your vehicle, or
because the b rake booste r has somehow
been damaged, the brake pedal must be
pressed considerab ly harder to make up
for the lack of booster assistance .
Servotronic® -
advanced power
steering system
The power steering systems use the power of
the running engine to allow precise steering
with little effort.
The advanced Servotronic ® power steering
system senses the road speed and e lectroni­
cally adjusts powe r ass istance to p rov ide com ­
fortable and sa fe stee ring response exactly
matc hed to the ve hicle speed .
Power steering w il l not work if the eng ine is
off . As a result, the steering whee l w ill be hard
to turn.
The power steering fluid level is chec ked dur­
ing the scheduled ma intenance serv ices.
(D Note
If there is an e lectronic malfunction, ser­
votronic
will still function like a conven­
tiona l power steering system, providing a
constant steering support force that is no
l onger proportionate to the vehicle speed.
This is most not iceable when t urning the
steering wheel at low speeds (for example
when pa rking), - more effort w ill be re­
q uired than us ual.
- Be aware of the diffe rent than usual
steering response and adjust your steer­
ing force acco rding ly.
- Have the problem checked and set right
by an A udi dealer as soon as poss ible.
(D Tips
- When the eng ine is running, never ho ld
the stee ring wheel turned all the way to
the rig ht or to the left fo r longer than 15
seconds. The powe r stee ring pump will
overheat the hydraulic fluid i f yo u keep
holding the stee ring wheel turned all the
way. This is likely to damage the power steering system.
- If the powe r steering system sho uld fai l
entire ly, or if the engine is not runn ing
(for example, wh ile be ing towed), you
w ill still be able to stee r the veh icle.
However,
considerably more effort will
be requi red to do so.
- If the power steering system should
have a leak, or is not functioning proper­
ly, contact your author ized Audi dealer
immed iately.
- The power steer ing system req uires a
specially fo rmu lated hyd raulic fluid. The
powe r stee ring fluid reservoir is located
in the engine comp art ment¢
page 234.
T he cor rect fluid level in the reservoir is
impo rtant fo r proper functioning of the
powe r stee ring .

Cleaning and protect ion
General information
Regular core preserves vehicle value.
Any automobile is exposed to industrial
fumes , corrosive road salt, etc. A well cared
for Audi can look like new many years after
purchase . Regu lar and correct care w ill con­
tr ibute to maintaining the beauty and value of
your Aud i.
F u rth ermor e, good c are may be a conditi on
for subs tantiati ng a w arrant y cla im sho uld
c orrosion d amag e or paint d efects oc cur.
Your authorized Audi dealer has a variety of
dedic ated veh icle-car e products and can ad ­
vise which ones to use for cleaning the exter i­
or and interior of your vehicle.
Whether you use products recommended by
Aud i or other commercially available clean ing
agents, please make sure you apply them cor­
rectly .
A WARNING
-Cleaning agents may be poisonous. Keep
them out of the reach of children.
- Heed all caut ion labels.
- Always read directions on the container
before using any product. Follow the di­
rect ions carefu lly.
- Most chemical cleaners are concentrated
and have to be diluted .
- Use spot removing fluids only in well
ventilated areas.
- Do not use gasoline, kerosene, d iesel
fuel, nail polish remover or other volatile
fluids. They may be toxic, flammab le or
haza rdous in other ways. Do not wash,
wax or dry the vehicle with the ign it ion
on or the engine running.
- Do not clean the undersides of chassis,
fenders, wheel covers, e tc. w ithout pro­
tecting your hands and arms. You may c u t yourself on sharp -edged metal parts .
Cleaning and protec tion 215
- Moisture and ice on brakes may impair
brak ing effic iency¢
page 200, General
information.
Test the brakes carefully
each time you wash the vehicle.
@) For the sake of the environment
Select on ly environmentally friend ly clean­
i ng products . Leftover cleaning products
should not d isposed of in the household
waste.
Care of exterior
Washing
Frequent washing protects the vehicle .
The best protection against environmental i n­
fluences is
frequent washing and waxing . How
often t his is required depends on:
- How much the veh icle is used
- Where the veh icle is parked (garage, in the
open under trees, etc.)
- The seasonal and weather conditions
- Environmental infl uences
T he longer b ird droppings, insects, tree resin,
road and indus tria l gr ime, ta r, soot, road salt
and other materials remain on the vehicle
body, the more lasting their destructive ef­
fects wi ll be . High temperatures caused by ex­
posure to intense sun light intens ify the corro­
s ive effect, particularly when humid ity is high
as well.
Under certain circumstances,
weekl y washing
may be necessary. Under other cond itions, a
monthly washing and waxing may be ade­
quate .
After the winter, the underside of the vehicle
should be thoroughly washed, preferab ly in a
professional car wash .
