- If the indicator light and the message ap­
pear
w hile dri ving , the emergency braking
function may not be available. It may not be
poss ible to set the parking brake or release
it once it has been set. Seek professional as­
s istance .
(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 the light comes on, an audible warning
signal is also given.
& WARNING
- Always observe the warnings in
~ page 205, Engine compartment, be­
fore opening the hood and checking the brake flu id.
- Driv ing with low b rake fluid is a safety
haza rd. Stop the car and get professional
assistance.
- USA models: If the 1111 warn ing light,
the . warning light and
thee warn­
ing light come on together, the rear
wheels co uld lock up fi rst unde r hard
braking . Rear wheel lock -up can cause
loss of vehicle contro l and an accident.
Have your vehicle repaired immediately
by your authorized Audi dea ler or a quali­
fied workshop. Drive slowly and avoid
sudden, hard brake applications.
-Canada models: If the brake warn ing
light ., the
DJ warn ing light and the
ABS warning light
liJ come on togethe r,
the rear wheels could lock up fi rst unde r
hard bra king. Rear wheel lock-up can
c ause loss of vehicle control and an a cc i­
dent. Have yo ur vehicle repaire d immed i­
ately by your authorized A udi dealer or a
qualified wo rkshop . Drive slowly and
avo id sudden, hard brake applicat ions.
- If the brake warning/indicator light does
not go out after a few seconds and the
parking brake is released, or lights up
whi le you are driv ing, the fluid level in
the brake fluid reservoir is too low. If you believe that
it is safe to do so, proceed
immed iate ly at low speed to the nearest
authorized Audi dealer or qualif ied 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
veh icle. Do not rely on strained brakes to
respond with max imum stopping power
in critical s ituations. You m ust allow fo r
increased braking distances . The extra
d istance used up by fading brakes could
lead to an accident.
· ~fu /C®) Electromechanical parking brake
The warning/indicator light monitors the
electromechanical parking brake.
If the indicator l igh t. (USA models)/ .

~ I !f Safety systems
The fl (USA models) ;fll (Canada models) in­
d icator light monitors the safety systems (e.g .
a irbags, pretensioners) and ill uminates for a
few seconds each time you switch the ignition
on .
If the
fl (USA models)/ E,I (Canada mode ls)
indicator light does not go out, or if it illumi­
nates wh ile 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 illum inate
when you switch the ignition on, this also
means the re is a ma lfunction.

Braking
What affects braking efficiency?
Ne w brake p ads
During the first 250 miles (400 km), new
-
brake pads do not possess the ir full brak ing
effect, they have to be "broken in" first
c:> .&.. .,.

182 Intelligent technology
You can compensate for this slightly reduced
braking power by pushing harder on the brake
pedal. Avoid heavy braking loads d uring the
break-in per iod.
Operating condition s and d riv ing hab it s
The brakes on today 's automob iles are st ill
subject to wear, depending largely on operat ­
ing 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 author­
ized Audi dealer more often than specified in
the
Warra nty & Maint enance booklet . Failure
to have your brake pads inspected can result in red uced b rake pe rformance.
On steep slopes, you should use the brak ing
effect of the engine . Th is way, you prevent un­
necessa ry wear on the brake system. If you
must use yo ur brakes, do not hold the brakes
down continuously . P u mp the brakes at inter ­
va ls.
Operating noise
Noises may occur when braking depending on
the speed, braking fo rce and outside condi­
tions s uch as temperature and humidity .
Effect of w ater and ro ad s alt
In certain situat ions, for example after driving
through water, in heavy ra in, after overn ight
condensat ion or after washing your car, the
b rak ing effect can be reduced by moistu re or
ice on the bra ke roto rs and b rake pads . The
b rakes must be dried fi rst with a few caref ul
b rake app lications .
At higher speeds and with the w indshield w ip­
e rs turned on, the brake pads press agains t
the brake rotors for a short amount of time.
This occurs at regular intervals without 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 driven on a salt-covered road and the brakes are not used. Likewise,
you clean
off accumulated sa lt coating from brake d
iscs and pads with a few cautio us ap­
plications of the brake
Q ,&. .
Corrosion
The re may be a tendency for dirt to bu ild up
o n the brake pads and corros io n to fo rm on
the d iscs if the car is not driven regu la rly or
only for short trips with litt le use of the
brakes.
If the brakes a re not used frequently, o r 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
c> &. .
Faults in the brak e syst em
If you shou ld no tice a sudden increase in
brake pedal trave l, then one of the two brake
ci rcuits may have fai led
c> &. .
Lo w brake fluid lev el
Malfunctions can occu r in the bra ke system if
the b rake fluid level is too low. The brake f lu id
level is monitored electronically.
Brake booster
The brake booster increases the pressure that
yo u generate with the brake peda l. It works
o n ly when the engine is running .¢
&
Brake lining we ar status
Brake lining wear may be checked by visual in­
spect ion of the condition of the brake pads
through the open ings in the wheel. If neces­
sary, the wheel may be removed for th is i n­
spect io n ¢
page 249, Changing a wheel.
_&. WARNING
- New brake pads don't have the bes t stop­
p ing power and m ust be "bro ken-in" dur­
ing the initial 100 to 150 miles (150 to
200 kilometers) of normal city driving.
You can compensate for this by pressing
the brake pedal more firmly. Th is also
applies later when new pads are instal­ led.

-You should perform braking maneuvers
for the purpose of clean ing the brake
system only if road condit ions permit.
Other road users must not be put at r isk -
you may cause an acc ident!
- Before descending a steep grade, reduce
speed and shift transmiss ion into a lower
gear or lower d riving range . Do not ride
the brakes or hold the pedal down too
long or too often. This cou ld cause the
brakes to get hot and dimin ish braking
effi ciency.
- Do not "r ide the b rakes" by resting your
foot on the pedal when yo u do not intend
to brake. This may cause the b rakes to
overheat, premat ure wear and increased
stopp ing distance .
- Under certain climatic and operating
conditions such as passing through wa­
ter, driving in heavy rain or after wash ing
the vehicle, the effect iveness of the
brakes can be reduced. In winter, ice can
accumulate on the brake pads, linings,
discs and d rums . Carefully apply brakes
for a test. Brakes will dry and ice coat­ ings will be cleaned off afte r a few ca re­
f ul brake appl ications.
- Driv ing fo r an ex tended pe riod of time on
salt-covered ro ads w ithout using yo ur
brakes can also affect braking efficiency.
Clean off accumu lated salt coating from
brake discs and pads with a few caref ul
brake applicat ions.
- 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 co uld
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 author ized Audi dealer or qualified
wor kshop.
- Never let the v ehicle roll to a stop w ith
t he engine shu t off.
Int ellig ent technolog y 183
-If the brake booster is not working, for
examp le when towing your vehicle, or
because the brake booster has somehow
been damaged, the brake pedal must be
pressed conside rably harder to make up
for the lack of booster assistance .

The electro-mechanical power assist helps
the driver when steering .
Power steer ing adapts electronically based on
the vehicle speed.
Indicator lights and messages
• Steering defecti ve! Do not d rive vehicle!
If this indicator light turns on and stays on
and t his message appears, the power steer ing
may have failed .
Do
not con tinue dr iv ing . See your author ized
Audi dealer or other qualified repair facility
fo r ass istance.
f-r,ij Dynamic st eering: System fault! You can
continue driving
If the indicator light turns on and the mes­
sage appears, the steering may be more diffi­
cu lt to move or more sensit ive tha n usual. The
stee ring wheel may a lso be at an angle when
driv ing straight .
Drive slowly to your a uthorized Audi dea ler or
qualified workshop to have the ma lfunction
correc ted .
fifl Dynamic steer ing: in itializing
If this drive r message appea rs and the indica ­
tor light is flash ing on the instrument panel,
dynamic steer ing * is being rein itia lized. Once
you start the engine after th is is finished, the
steering wheel will be easy to move. Re- init i­
al ization might be necessa ry if the steering
wheel was moved ha rd to the left a nd right
wh ile the vehicle was not moving. The display
goes ou t as soon as initialization is comp lete. .,.

188 Driving and en vironm ent
8_ 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 braking effect.
CD 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 switc h the engine off when driving
t hr ough water.
- Keep in mind that oncoming vehicles
may c reate waves that raise the water
l evel and make it too deep fo r you r vehi­
cle to dr ive through safely.
-
- Avoid dr iving thro ugh salt 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 on environmentally sound manner.
,,. Always use lead-free gasoli ne¢ page 207,
Fuel supply .
,,. Never run the tank down a ll the way to
empty.
,,. Never put too much motor oil in your en-
gine ¢
page 217, "t':::r. Adding engine oil.
,,. Never t ry to push- o r tow-start your veh icle.
The catalytic converter is an effic ient "clean­
up" device built into the exhaust system of
the vehicle. The catalytic converter burns
many of the polluta nts in the exhaust gas be­
fore they are released into the atmosphe re. The exclusive
use of unleaded f uel is critica lly
important for the life of the catalytic convert­
er and proper funct ion ing of the eng ine .
A WARNING
= -
-Do not park or operate the vehicle in
areas where the hot exhaust system may
come in co ntact with dry grass, brush,
fuel spill or other material wh ich can
cause a fire .
- Do not app ly additional undercoating or
r u stp roofing on or nea r the exhaust
manifold, exhaust pipes, cataly tic con­
ver ter or heat shields. Dur ing driv ing, the
substance used for under coa ting co uld
overhea t and cause a fire.
CD Note
- Be aware that just o ne tank filling with
leaded fu el w ill already ser io usly de ­
gr ad e the per form ance o f the catalytic
c onverte r.
- Do not ex ceed t he corre ct engine oil level

- Do not drive until the fuel tank be co m es
completely emp ty. The engine co uld mis­
fire . Unburned fuel could also get in to
the exhaust system and this co uld cause
the cata lytic converter to overheat .
- Do not turn off the igni tion whi le the ve ­
hicle is mov ing.
- Do not contin ue to ope rate your veh icle
unde r these conditions, as otherwise fuel
can reach the catalyt ic converte r. T his
co uld resu lt 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 p rope rly

222 Check ing and filling
• Read the brake fluid leve l from the brake
fluid reservoir ¢
fig. 179, ¢ fig. 175. The
brake f lu id leve l must be between the "MIN"
and "MAX" markings.
The brake fluid reservoir is located at the rear partition of the engine compartment on the
left side ¢
page 214 .
The fluid level may drop slightly after some
time due to the automatic adjustment of the brake pads . This is not cause for alarm .
I f the brake fluid level falls
considerably be­
l ow the "MIN" mark, the brake wa rning/indi ­
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 should be thoroughly checked
by an authorized Audi dealer or qualified
workshop and the cause corrected . If the
brake fluid level is too low, the b rake war ning/
i ndicato r light w ill illuminate . Contact an au­
thor ized Audi dealer
imm ediately .
@ Tips
The brake f lu id reservoir is located unde r­
neath the cove r.
Changing brake fluid
Have the brake fluid changed by an experi­
enced technician .
Brake fluid absorbs moisture from the a ir . If
the water content in the brake fluid is too
h igh, corrosion in the brake system may result
after a per iod of t ime . The bo iling po int of the
b rake fluid w ill also decrease considerably and
dec rease braking per formance.
Therefore, the brake flu id must be changed
e ver y two ye ars. A lways use new b rake fluid
which confo rms to Fede ral Motor Vehicle
S tanda rd "FMVSS 116 DO T 4".
The brake flu id reservoir can be difficult to
r each, therefo re , we recommend that yo u
have the brake fl uid changed by yo ur au tho r­
i z ed
Audi dealer . Your dealer has the co rrec t tools, the
right brake flu id and t he know -how
to do this for you.
A WARNING
'-
- Brake flu id is poisonous. It must be stor-
ed only in the closed or igina l 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 f luid that meets SA E
spe cifi cat ion
J 17 03 and conforms to
Federa l Motor Vehi cle Standard 1 16.
Always chec k with yo ur authorized A udi
dealer to make sure yo u are using the
correct brake fluid. The cor rect type of
brake flu id is also ind icated on the
brake f lu id reservoir.
- The brake fluid must be new. Heavy use
of the brakes can cause a vapor lock if
the brake fluid is left i n the system too
long . This can se riously affect the effi­
c iency of the brakes as well as your
safety . T his could result in an accident.
W Note
Brake fluid will damage the pai nt of you r
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 and the necessary expertise, we
r ecommend that yo u have the brake flu id
changed by yo ur autho rized Aud i dea le r.
Battery
General information
U nder normal operat ing cond itions, the bat­
te ry in your Audi does not need any ma inte­
nance. With
high outside temperatu res or
