When the light comes on, an audib le warning
signal is also given .
A WARNING
-Always observe the warnings in
¢ page 208, Engine compartment, be­
fore opening the hood and checking the brake flu id .
- Driv ing with low brake fluid is a safety
hazard. Stop the car and get professional
assistance.
- USA models: If the 1111 warn ing light,
the
G1 warning light and the m;B warn­
ing light come on together, the rear
wheels co uld lock up first unde r hard
braking. Rear wheel lock-up can cause
loss of vehicle con tro l an d an accident .
Have your vehicle repai red immedia tely
by your aut ho rized Audi dea le r or a quali ­
fied workshop. Drive slowly and avoid sudden, hard brake applications.
- Canada models: If the brake warn ing
light ., the
DJ warning light and the
ABS warning light
BJ come on together,
the rear wheels could lock up first unde r
hard braking. Rear wheel lock-up can
cause loss of vehicle control and an acc i­
dent . Have yo ur vehicle repaired immed i­
ately by your authori zed A udi dealer or a
qu alifie d wo rkshop. Dr ive slowly and
avo id su dden, hard brake appli cat ions.
- If the brake warning/indicator light does
no t go out afte r a few se con ds and the
par king brake is released, or lights up
whi le you are driving, the fluid level in
the brake f luid 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 severa l
brake applications, you will need greater
pressure on the brake pedal to stop your
veh icle. Do not rely on strained brakes to
respond with max imum stopping power
in critical s ituations . You must allow for
increased braking distances. The extra
d istance used up by fading bra kes could
le ad to an ac cident.
:l~/(®) Electromechanical parking brake
The warning/indicator light monitors the
electromechanical parking brake .
If the indicator light. (USA models)/ .

I I !f Safety systems
The fl (USA models),£,1 (Canada models) in­
dicator light monitors the safety systems (e.g.
airbags, pretensioners) and ill uminates for a
few seconds each time you switch the ignition
on.
If the fl (USA models)/ fll (Canada mode ls)
indicator light does not go out, or if it illumi­
nates while you are driv ing, or if it starts to
blink, then there is a ma lfunction somewhere
in the system.
If the light does not illuminate
when you switch the ignition on, this also
means there is a malfunction.
& WARNING
If you have a malfunction in the safety sys­
tems, contact your author ized Audi dealer
immediate ly. Otherw ise the safety sys­
t ems may not work properly in an acci­
dent.

Braking
What affects braking efficiency?
New brake pads
During the first 250 miles (400 km), new
brake pads do not possess their full braking
effect, they have to be "broken in" first¢& .
You can compensate for this slightly reduced braking power by pushing harder on the brake
pedal. Avoid heavy braking loads during the
break-in per iod.
Operating conditions and driv ing habits
The brakes on today's automobi les are sti ll
subject to wear, depending largely on operat ­
ing conditions and driving habits¢.&. . On
vehicles that are e ither driven mostly in stop­
and-go city traffic or are driven hard, the
brake pads should be checked by your author­
ized Audi dealer more often than specified in
the
Warranty & Maintenance booklet . Failure
to have your b rake pads inspected can result
in red uced brake performance.
On steep slopes, you shou ld use the brak ing
effect of the engine. This way, you p revent un­
necessary wear on the brake system.
If you
must use yo ur brakes, do not hold the brakes
down continuously. Pump the brakes at inter­
va ls.
Operating noise
Noises may occur when braking depending on
the speed, braking force and outside condi­
tions such as temperature and humidity.
Effect of water and road salt
In certain situat ions, for example after driving
through water, in heavy ra in, after overnight
condensation or after washing your car, the
braking effect can be reduced by moisture or
ice on the brake roto rs and brake pads . The
brakes must be dried first with a few careful
brake applications .
A t hi gher speeds and with the windshield w ip­
ers turned on, the brake pads press against
the brake rotors for a short amount of time .
This occurs at regular intervals without the
Intelligent technology 187
driver noticing and provides for better brake
response time under wet conditions .
T he effectiveness of the brakes can be red uced
when the vehicle is driven on a sa lt-co vered
road and the b rakes are not used. Likewise,
you clean off accumulated salt coating from
brake discs and pads with a few cautious ap­
plications of the brake ¢ & .
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 driven regu larly or
on ly for short trips with litt le use of the
brakes.
If the brakes are not used frequently, or if cor ­
rosion 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 trave l, then one of the two brake
c ircuits 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 electronica lly.
Brake booster
T he brake booster increases the pressure that
you generate with the brake peda l. It works
only when the engine is runn ing .¢ .&.
Brake lining wear status
Brake lining wear may be checked by visual in­
spection of the condition of the brake pads
through the openings in the wheel. If neces­
sary, the wheel may be removed fo r this in­
spection ¢
page 252, Changing a wheel .
A WARNING
-
- New brake pads don't have the best stop­
ping power and must be "broken-in" dur-
ing the initial 100 to 150 miles (150 to
~
•
•

188 Intelligent technology
200 kilometers) of normal city driving.
You can compensate for this by pressing
the brake pedal more firmly. This also applies later when new pads are instal­
led .
- 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 acc ident!
- Before descending a steep grade, reduce
speed and shift transmission 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 cause the
brakes to get hot and diminish braking
efficiency.
- Do not "ride the brakes" by resting your
foot on the pedal when you do not intend
to brake . This may cause the brakes to
overheat, premature wear and increased
stopping distance.
- Under certain climatic and operating
conditions such as passing through wa­
ter, driving in heavy rain or after washing
the vehicle, the effectiveness of the
brakes can be reduced. In winter, ice can
accumulate on the brake pads, linings,
discs and drums. Carefully apply brakes
for a test. Brakes will dry and ice coat­
ings will be cleaned off after a few care­
ful brake applications.
- Driving for an extended period of time on
salt-covered roads without using your
brakes can also affect braking efficiency.
Clean off accumulated salt coating from
brake discs and pads with a few careful
brake applications.
- If you damage the front 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 entire brake system.
- Failure of one brake c ircuit will impair
the braking capability resulting in an in­
creased stopping distance. Avoid driv ing
the vehicle and have it towed to the near- est authorized Audi dealer or
qualified
workshop.
- Never let the vehicle roll to a stop with
the engine shut off.
- If the brake booster is not working, for
example when towing your vehicle, or
because the brake booster has somehow
been damaged, the brake pedal must be
pressed considerably harder to make up
for the lack of booster assistance.
Electro-mechanical
power assist, dynamic
steering
The electro-mechanical power assist helps
the driver when steering.
Power steering adapts electronically based on
the vehicle speed .
Indicator lights and messages
• Steering defective! Do not drive vehicle!
If this indicator light turns on and stays on
and this message appears, the power steering
may have failed.
Do
not continue driving . See your authorized
Audi dealer or other qualified repair facility
for assistance.
E!"4 Dynamic steering: System fault! You can
continue driving
If the indicator light turns on and the mes­
sage appears, the steering may be more diffi­
cult to move or more sensitive than usual. The
steering wheel may also be at an angle when
driving straight .
Drive slowly to your authorized Audi dealer or
qualified workshop to have the malfunction
corrected .
ls!'fl Dynamic steering: initializing

you start the engine after this is finished, the ..,..

A WARNING ,~ ~
After driving through water, mud, slush,
etc., the brakes may be slow to take effect
because of wet brake rotors and pads. Dry
the brakes first by braking carefully to re­
store the full brak ing effect.
([) Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys­
tem can be severely damaged by driving
through wate r.
@ Tips
- Check the depth of the water before dr iv­
i ng through it.
- Do not stop the veh icle, dr ive in reverse
or switch the engine off when driving
th rough water.
- Keep in mind that oncoming vehicles
may create waves that raise the water
level and make it too deep for you r vehi­
cle to drive th rough safely.
- Avoid dr iving through sa lt water because
i t can ca use corrosion.
Catalytic converter
It is very important that your emission con­
trol system (catalytic converter) is function ­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner.
11-Always use lead-free gasoline q page 210,
Fuel supply .
"'" Never run the tank down a ll the way to
empty.
11-Never put too much motor oil in your en-
gine
q page 220, ~ Adding engine oil .
11-Never try to push -or tow-start your veh icle .
The catalytic converter is an efficient "clean­ up" device built into the exhaust system of
the vehicle . The catalytic converter burns
many of the pollutants in the exhaust gas be­
fore they are released into the atmosphere .
Drivin g and en vironm ent 193
The exclusive use of unleaded fuel is critically
important for the life of the catalytic convert­
er and proper funct ion ing of the engine.
A WARNING
-
- Do not park or operate the vehicle in
areas where the hot exhaust system may
come in contact with dry grass, brush,
fuel spill or other mate rial wh ich can
cause a fir e.
- Do not apply additional undercoating or rustp roof ing on or near the exhaust
manifold, exhaust pipes, catalytic con­
ve rter or heat shields. During driv ing, the
substance used for undercoating co uld
overheat and cause a fire.
(D Note
- Be aware that just one tank filling with
leaded fu el w il l already ser iously de­
gra de the performance of the catalytic
c onverte r.
- Do not ex ceed t he cor rect eng ine oil level
qpage 220.
- Do not drive until the fue l tank becomes
comple tely empty. The engine co uld m is­
fire . Unburned fuel could also get in to
the exhaust system and th is co uld cause
the catalytic converter to overheat .
- Do not turn off the ignition while the ve ­
hicle is moving.
- Do not continue to ope rate your veh icle
unde r these conditions, as otherwise fuel
can reach the catalytic converte r. T his
cou ld result in overheating of the con­
verter, requir ing its replacement.
- To assure efficient operation of the Emis ­
sion Control System:
- H ave you r vehicle maintained prope rly
and in accorda nce w ith the serv ice rec­
ommendat ions in yo ur Warranty &
M ain tenance boo klet.
- L ack of prope r maintenance as we ll as
improper use of the vehi cle w ill impair
the function of the em ission contro l
system and could lead to damage . ..,. •

~ Read the brake fluid level from the brake
fluid reservoir ¢
fig. 171, ¢ page 217,
fig . 167.
T he brake fluid level must be be ­
tween the "MIN" and "MAX" markings.
The brake f luid reservoir is located at the rear
partition of the engine compartment on the
l eft side ¢
page 217 .
The fluid level may drop slightly after some
time due to the automatic adjustment of the brake pads . This is not cause for alarm .
If the brake fluid level falls considerably be­
l ow the "M IN" mark, the bra ke wa rning/ind i­
cator light (U .S . mode ls:
1111 , Canadian
models: .) will come on
¢ page 15. Do not
continue to operate the vehicle. The complete
brake system shou ld be thoroughly checked
by an authorized Audi dealer or qualified
workshop and the cause co rrected . If the
b rake fluid level is too low, the b rake wa rn ing/
i nd icator lig ht w ill illuminate . Co ntact an a u­
thor ized Audi dealer immediately.
@ Tips
The brake f luid rese rvoir is located unde r­
neath the cove r.
Changing brake fluid
Have the brake fluid changed by an experi­
enc ed technician .
Brake fluid ab sorbs moisture from the a ir. If
the water content in the brake fluid is too
hi gh, corrosion in the b rake system may result
after a per iod of t ime . The bo iling po int of t he
b ra ke fluid w ill also decrease con siderab ly and
d ec rease brak ing per forman ce.
Therefore, the brake flu id must be changed
every two year s. Always use new b ra ke fluid
which confo rms to Fede ral Motor Vehicle
S tand ard "FMVSS 1 16 DOT 4".
The brake flu id rese rvoir can be difficult to
r eac h, therefo re , we recommend that yo u
have the brake fl uid changed by yo ur aut ho r­
iz ed Audi dealer. Your dealer has the correc t
Checking and fillin g 225
tools, the right brake fl uid and t he know -how
to do this for you .
A WARNING
- Brake fl uid is poisonous. It must be stor­
ed only in the closed or iginal container
out of the reach of children!
- Brake failure can res ult from o ld or inap­
propriate brake f lu id. Observe these pre­
cautions:
- Use only brake fluid th at mee ts SA E
spe cificat ion
J 17 03 and conforms to
Fe dera l Mo to r Ve hicl e Standard 1 16.
Always check with yo ur autho rized Au di
dealer to make sure yo u are using the
correct brake fluid. The c orrect type of
brake f luid is also ind icated on t he
brake f luid reservoir .
- The bra ke fl uid must be new. Heavy use
of the brakes ca n cause a vapor lock if
the b rake fluid is left i n the system too
long. This can se riously affect the effi­
c iency of the b rakes as well as your
safety , T his could result in an accide nt.
(!) Note
Brake fluid will damage the pai nt of your
vehicle.
@) For the sake of the environment
Because of the prob lem of proper disposal
of brake fluid as well as the spec ial too ls
r equired an d th e nec essary exper tise, w e
r ecomme nd that yo u have th e brake flu id
c hanged by yo ur aut ho rize d Aud i dea le r.
Battery
General information
U nder normal operating cond itions, the bat­
te ry in your Audi does not need any ma inte­
nance . With
high outside temperat ures or
lo ng da ily drives we recommend that you have
t h e e lectrolyte leve l che cked by an autho riz ed
A udi de aler or qu alified workshop. The elec­
tro lyte leve l should also be checked e ach time
