The warning/indicator light flashes if brake
fluid level is low, if there is an ABS system
malfunction or a parking brake malfunction.
The 1111 (USA models)/ . (Canada models)
light illuminates when the ign ition is turned
on .
It goes out after the engine has been
started. This indicates t hat the brake war ning
light is funct ion ing properly.
If th e br ake w ar ning light d oes not light up

A WARNING
- USA models: If the 1111 warning l ight
and
the m warning light come on to ­
gether, the rear wheels could lock up
first under hard braking . Rear wheel lock ­
up can cause loss of vehicle control and
an acc ident. Have your vehicle repaired
immediately by your authorized Audi
dealer or a qualified workshop . Dr ive
slowly and avoid sudden, hard brake ap·
plicat ions.
- Canada models: If the brake warn ing
light . and the ABS warning light
II]
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 vehi­
cle repaired immed iately by your author·
ized Audi dealer or a qualified workshop .
Drive s low ly and avoid sudden, hard
brake applications.
- If the brake warning/ind icator light does
not go ou t after a few seconds and the
pa rking brake released, or lights up wh ile
you are driv ing, the fluid level in the
brake fluid reservoir is too low. If yo u be ­
lieve that it is safe to do so, proceed im­
mediately at low speed to the nearest
author ized Audi dealer or qualif ied 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 fo r
increased braking dis tances. The extra
distance used up by fading brakes could
lead to an accident.

(D Tips
The symbol's appearance might be differ­ent in some models .
Yellow symbols
A yellow symbol means WARNING.
Fig. 27 Display: Yellow warning symbo l
Yellow symbols indicate a priority 2 malfunc­
tion -Warning!
When a yellow warning symbol appears,
one
warning tone sounds. A driver message ap­
pears as well to explain the malfunction in
more deta il. The driver warning goes out after
about 5 seconds, but it can be brought up at
any time by pressing the
! SET I button aga in.
Check the funct ion displayed as soon as possi­
ble. The yellow symbol will not go out again
until the reason for the malfunction has been
corrected.
If several priority 2 malfunctions are present ,
the symbols appear in succession and remain
for about 2 seconds .

A WARNING ,~
The increased safety afforded by ASR does
not mean that you can take safety r isks .
Always adapt your driv ing style to the road
conditions and traffic situation .
@ Tips
To ensure that the ASR works properly, all
four wheels must be fitted with identical
tires. Any differences in rolling radius of
the t ires can cause the system to reduce
engine power when this is no t des ired. See
also ¢
page 263, New tires and replacing
tires and wheels.
Braking
General information
What affects braking efficiency?
Operating conditions and driving habits
The brakes on today's automob iles are st ill
subject to wea r, depend ing largely on operat ­
ing conditions and dr iving habits ~.&. . On ve­
h icles that are either driven mostly in stop­
and-go city traffic or are driven hard, the
brake pads should be checked by your a uthor­
ized Audi dealer more often than specified i n
the
Warranty & Maintenan ce booklet . Failure
to have your brake pads inspected can result
in red uced brake performance.
On steep slopes, you should use the brak ing
effect of the eng ine . This way, you p revent un­
n ecessary wea r on the brake system . If you
must use you r brakes, do not ho ld the bra kes
down continuously . Pu mp the b rakes at in ter ­
va ls.
Noises may occur when braking depending on
the speed, bra king for ce and outside condi­
tions s uch as temperatu re a nd humidity .
Moisture or road salt
If you are driving faster than 31 mph (SO km/
h) and the windsh ie ld w ipers are on, the brake
pads will briefly touch the b rake d iscs in regu­
l ar i nte rva ls so as to imp rove reaction t ime
Int ellig ent technolog y 207
when b rak ing on wet surfaces . You, the driver,
will not notice anything.
U nder certa in cond itions , fo r example, when
d riv ing th rough wa ter or very heavy ra in , or
even after washing your veh icle, the braking
effect can be reduced due to moisture (or in
freez ing cond itions ice) on the brake pads. A
few carefu l brake applications should dry off
the brake pads or remove any ice coatings.
The effectiveness of the brakes can be red uced
when the vehicle is driven on a salt-covered
road and the brakes are not used. Here too,
you should clean off accumulated salt coating
from brake discs and pads w ith a few careful
applications of the brake¢,&. .
Corrosi on
There may be a tendency for dirt to b uild up
on the brake pads and corros ion to form on
the d iscs if the car is not driven regularly or
o nly for short trips w ith litt le use of the
brakes .
If the brakes are no t used frequently, or if cor­
ros ion has formed on the discs, i t is adv isable
to clean off the pads and d iscs by braking
firmly a few times from a moderately high speed ¢,& .
Fault s in the brake s ystem
If you should notice a sudden increase in
brake pedal trave l, then one of the two brake
c ircuits may have failed ¢,&. .
Lo w br ake fluid le vel
Malfunctions can occ ur in the brake system if
the brake fluid level is too low. The brake flu id
level is monitored electronically.
Brake lining wea r status
Brake lining wear may be checked by visual in­
spection 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 in­
spection ¢

208 Intellig ent technol ogy
,8. WARNING
- You should perform braking maneuvers
for the purpose of cleaning the brake
system only if road condit ions permit .
Other road users must not be put at r isk -
you may cause an acc iden t!
- Before descending a steep grade, reduce
speed and shift transmiss ion into a lower
gear or lower driving 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 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
stopp ing distance.
- Under certain climatic and operating
condit ions such as passing through wa­
ter, driving in heavy ra in or after wash ing
the vehicle, the effect iveness of the
brakes can be reduced. In winter, ice can
accumula te 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.
- Driv ing fo r an extended period of time on
salt -covered roads w ithout using your
brakes can also affect braking efficiency.
Clean off accumulated salt coating from
brake discs and pads w ith a few careful
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 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 authorized Audi dealer 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
runn ing
c> .&. .
,8. WARNING
-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 bra ke pedal mus t be
pressed considerably harder to make up
for the lack of booster assistance.
Functioning of Anti-Lock Brake System
(ABS)
ABS prevents the wheels from locking up un­ der braking .
-
The ABS contributes effect ively to vehicle con­
trol since it prevents the whee ls from
locking
when the brakes are applied. This means that
the ve hicle remains steerable and is less likely
to skid .
With AB S you do n ot need to pump the
brake . Ju st hold th e bra ke p edal down.
However, do not expect the ABS to s horten
braking distance under
all c ircumstances.
When driving on gravel or on new ly fallen
snow on top of icy surfaces, braking dis tance
may be even longer, therefore, under these
circumstances, it is especia lly important that
you drive s low ly and with great care.
How the ABS syst em work s
An automat ic check is made when a speed o f
about 12 mph (20 km/h) is reached. When
this happens, a pumping noise can be heard.
If an ind iv idual whee l begi ns to rota te too
s lowly in re lation to vehicle speed and tends
to lock, the ABS automatically reduces brake pressure to prevent that whee l from locking . .,..

Driving and
environment
The first 1
1000
miles
(11500 km) and
afterwards
New engine
The engine needs to be run-in during the first
1,000 miles (1 ,500 km) .
For the fir st 600 mile s (1,000
kilometers ):
.,. Do not use full throttle.
.,. Do not d rive at engine speeds that are more
than 2/3 of the max imum permitted RPM .
From 600 to 1,000 miles (1 ,000 to
1,500 kilometers ):
.. Speeds ca n gradually be increased to the
maximum perm iss ible road or eng ine speed .
During and after br eak-in period
.. Do not rev the eng ine up to h igh speeds
when it is cold. Th is applies whether the
transmission is in N (Neutral) or in gear.
After the break- in peri od
.. Do not exceed maximum eng ine speed un­
der any circumstances.
.. Upshift into the next higher gear
before
reaching the red area at the end of the tach­
ometer scale
c.> page 10.
During the first few hours of driving, the en­
g ine's internal friction is higher than later
when all the moving parts have been broken
in . How well this break -in process is done de ­
pends to a considerable extent on the way the
vehicle is driven du ring the first 1,000 miles
(1,500 kilome ters).
(D Note
Extremely h igh engine speeds are auto­
mat ica lly reduc ed. However, t hese rpm
lim its are programmed for a n engine well
r u n- in, not a new engine.
Driving and environment 213
@) For the sake of the environment
Do not drive with unnecessarily high en­
g ine speeds -upshifting ear ly saves f uel,
reduces noise and protects the environ­
ment.
New tires
If your vehicle is running on new tires, drive
very carefully for the first 350 miles (500 ki lo­
meters) after fitting.
.&, WARNING
N ew tires tend to be sl ippery and mus t al­
so be "b roken -in" . Be sure to remember
this dur ing the f irst 350 m iles (500 kilo­
meters) . Brake gently . Avoid fo llowing
closely behind other vehicles or other sit­
uations that m ight require sudden, hard
b raking .
New brake pads
Remember that new brake pads do not have a
full brak ing effect dur ing the first 250 m iles
(400 ki lomete rs) afte r they are installed.
New brake pads have to be "burnished in" be­
fore they have optima l grab
c.> .&. .
During the brea k-in period, yo u should avo id
putting severe loads on the brakes. Severe
l oads include , for example, sudden hard brak­
i ng, in particular at very h igh speeds or, for
example, on mountain passes .
.&, WARNING
New b rake pads don 't have the best stop­
p ing power and must be "broken-i n" dur­
ing the initi al 100 to 150 miles (150 to
200 kilometers) o f no rma l ci ty driving . You
can compensate for this by pressing the b rake peda l more firm ly . This also applies
later when new pads are installed.

214 Driving and en vironm ent
Avoid damaging the
vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc ., make certain that
low-lying parts such as spoilers and exhaust
system parts do not bottom out and get dam­
aged.
This is especially true for vehicles with low­
slung chassis (sports chassis) * and fully load­
ed veh icles .
Driving through water
on roads
Note the following to avoid vehicle damage
when driving through water, for example on
flooded roads:
- T he water must not be any higher tha n the
bottom o f the vehicle body.
- Do not d rive faster than wa lking speed.
_& WARNING
After d riving through water, m ud, slush,
et c., the brakes may be slow to take effect
because o f wet brake ro tors and pads . Dry
the brakes fi rst by braking carefully to re­
store the full braking effect.
(]) Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys ­
tem can be severely damaged by driving
through water.
- Check the depth o f the water before driv ­
ing through it.
- Do not stop the veh icle, dr ive in reverse
or switch the engine
off when driving
through water.
- Keep in mind that oncoming vehicles may create waves that raise the water
level and make it too deep for your vehi­
cle to drive through safely.
- Avoid driving thro ugh salt water because
it 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.
.,. Always use lead-free gasoline¢ page 232,
Fuel supply .
.,. Never run the tank down all the way to
empty .
.,. Never put too much motor o il in your en-
gine ¢
page 242, ~ Adding engine oil .
.,. Never try to push- or tow-sta rt you r vehicle.
The catalytic converter is an efficient "clean­
u p" dev ice built into the exhaust system of
the vehi cle. The cata lytic conve rter bu rns
many of the pollu tan ts in the exha ust gas be­
f o re they are re leased into the atmosphere.
T he exclusive use of unleaded fuel is critically
important for the life of the catalyt ic convert­
er and prope r fu nct ion ing of the engine.
A WARNING
- Do not park or operate the vehicle in
areas where the hot ex haust system may
come in contact with dry grass, brush,
fue l spill or other material wh ich can
cause a fire.
- Do not app ly additiona l undercoating or
r u stproofing on or near the exhaust
manifold, exhaust pipes, catalytic con­
verter or heat sh ields. Dur ing driv ing, the
substance used fo r undercoating could
overheat and cause a fire.
(D Note
- Be aware that just one tank filling with
leaded fuel will already ser iously de-
grade the performance of the catalytic
converte r.
- Do not exceed the correct engine oil level
¢page 242.
-Do not drive until the fuel tank becomes
completely empty . The engine co uld mis-
fire. Unburned fuel could also get into ..,.
