A WARNING
-Always observe the warn ings in
Q page 195, before openi ng the hood
and checking the brake flu id.
- Driving with low brake fluid is a safety
ha zard . Stop the car and get professiona l
assis tance.
- I f the
1111 (USA models) ;II (Canada
models) brake system ind icator light
turns on together with the ABS and ESC
indicator lights, the ABS/ESC regulating
function may have failed. Functions that
stabilize the vehicle are no longer avai la­
ble. This could cause the vehicle to
swerve and increase the r isk of slid ing .
Drive carefully to the nearest authorized
Aud i deale r or other q ualified workshop
and have the malfunction corrected .
- If the brake warning/ind icator light does
not go out after a few seconds and the
pa rking brake is re leased, or lights up
while you are dr iving, t he f lu id leve l in

o Malfunction Indicator Lamp (MIL)
The Ma lfunction Indicator Lamp (MIL) is part
of the On-Board Diagnostic (OBD II) system.
T he symbo l¢• lights up when the ignition is
switched on and will turn off after the engine
has started and has settled at a constant idle
speed. This indicates that the MIL is working
proper ly.
T he warning light illuminates when the re is a
malfunction in the engine electronic system.
Contact your a uthorized Audi dea ler and have
the malfunction corrected.
An improperly closed fuel filler cap may a lso
cause the MIL light to ill uminate ~ page 192.

!7 Engine speed limitation
App lies to vehicles: wi th engine speed l imitatio n
111 Do not exceed max. engine speed of
XX.XX rpm
The eng ine speed is automatically limited to
the speed displayed in the driver information
system. This protects the engine from over ­
heating.
T he eng ine speed limitation deactivates once
the engine is no longer in the critical tempera­
ture range and you have re leased the accelera­
tor pedal once.
If the engine speed limitation was activated
by an engine control malfunction, the indica-
tor light
13:a also turns on. Make sure that the
speed does not go above the speed displayed. "'"

174 Intelligent technology
Braking
What affects braking efficiency?
New brake pad s
Du ring the first 2 50 miles (400 k m), new
b ra ke pads do not possess their fu ll braking
effect , they have to be "broken in" first¢.&. .
The break-in period can be considerably lon­
ger for vehicles with ceramic brake rotors*.
You can compensate for this slightly reduced br aking power by push ing harder on the brake
pedal. Avoid heavy braking loads during the
b reak-in per iod.
Operating conditions and d riving h abits
The brakes on today's automobi les are st ill
subject to wear, depend ing largely on operat­
ing conditions and dr iv ing habits ¢.&. . On
vehicles that are e ithe r dr iven mostly in stop­
and-go city traffic o r are driven ha rd, the
b rake pads should be checked by you r aut hor­
iz ed A udi de aler more often than specified in
the
Warrant y & Maintenan ce booklet . Fail ure
to have your b ra ke pads inspected can resu lt
in red uced brake performance.
On steep slopes, yo u sh ou ld use t he b ra ki ng
effect of the eng ine. Th is w ay, you preven t un­
necessa ry wear on the brake system . If you
must use yo ur brakes, do not ho ld the brakes
down continuously. P ump the brakes at inter ­
va ls.
Operating noise
N oises may occur when braking depending on
the speed, braking fo rce and outside condi­
tions s uch as temperature a nd h umidity.
Due to the na ture of the mate rials used i n ce­
ramic brake rotors*, noises may become more
apparent at low speeds.
Effect of water and road salt
I n ce rtain situat ions, for exampl e after d riving
throug h wate r, in heavy ra in, after overn igh t
conde nsation or afte r washi ng your c ar, the
b ra ki ng effect can be reduced by moisture or
ice on the bra ke rotors and b rake pads. The brakes must be dr
ied first with a few careful
brake applications .
At highe r speeds and with the winds hield wip­
ers t urned on, the b ra ke pads press against
the b rake roto rs fo r a short amount o f time .
This occurs at regular intervals without the drive r not icing and p rov ides for better brake
response time under wet conditions.
The effectiveness of the brakes can be red uced
whe n the vehicle is driven on a sa lt -covered
road and the brakes are not used . Likewise,
you clean off accumulated salt coating from brake d iscs and pads with a few cautious ap­
plicat ions of the bra ke
¢ .&. .
D ue to the ir s urface characteristics, ceramic
brake rotors* absorb moisture in such condi­
tions . T his can cause a temporary reduction in
braking force compared to dry brakes . You can
compensate for th is by pressi ng the brake
p eda l harde r.
Corrosion
There may be a tende ncy for dirt to build up
on the brake pads and corros ion to form on
the d iscs if the car is not driven regu larly or
only for short trips w it h litt le use of the
brakes .
If the brakes are not used frequently, or if cor­
ros io n has formed on the discs, it is adv isable
to clean off the pads and discs by braking
firmly a few times from a moderately h igh
speed ¢.&. .
Faults in the brake system
If you shou ld notice a sudden increase in
brake pedal trave l, then one of the two brake
c ir cuits may have fa iled
c::> .&. .
Low brake fluid level
Malfunctions can occur in the brake system if
t h e brake fluid level is too low. The brake flu id
level is monitored electro nically .
Brake boo ster
The brake booster increases the pressure that
yo u generate with the brake peda l. It works
on ly when the engine is running

.&_ WARNING
- New brake pads do n't have the best sto p­
ping power and must be "broken-in" dur­
ing the init ial 100 to 1 50 m iles (150 to
200 k ilometers) of normal city driving.
T he break-in period can be considerably
longer for veh icles with ceram ic br ake ro­
tors*. You can compensate for this by pressing the brake pedal more firmly.
T his also applies later when new pads are
installed .
- You should perform braking maneuvers
for the purpose of cleaning the brake
system on ly 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 driving range. Do not ride
the brakes or hold the pedal down too
long or too ofte n. This cou ld cause the
brakes to get hot and d imin ish b raking
efficiency.
- Do not "r ide the brakes" by resting your
foot on the pedal when you do not inte nd
t o brake. Th is may cause the b rakes to
overheat, prema ture wear and inc reased
stopping distance .
- Under certa in climat ic and operating
conditions such as passing through wa ­
ter, driving in heavy rain or after wash ing
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 ca re­
ful brake applications.
- Driv ing fo r an extended pe riod of time on
salt-covered roads w ithout using you r
Intellig ent technolog y 175
brakes can a lso affect braking efficiency .
Clean off accum ulated 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
f low to the front brakes is not obstruct­
ed. Otherw ise the brake system could
overheat reducing t he effectiveness of
the entire brake system.
- Failure of one b rake circuit will impa ir
the braking capab ility result ing in an in­
creased s topping distance. Avoid driving
the vehicle and have it towed to the near­
est a utho rized Audi dea le r or q ualified
workshop.
- Never let the vehi cle roll to a stop with
the engine shut off.
- If the b ra ke booste r is no t working, the
brake peda l must be p ressed considera­
b ly harder to make up for the lack of
booster assistance .

180 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.
(D 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.
Warming up and
cooling down
-
By carefully warming up and cooling down
your ve hicle, you can he lp ensure that it is not
overstressed unnecessarily dur ing sporty driv ­
ing.
When warming up, the vehicle is d riven at a
maximum engine speed of 6000 RPM in order
to raise the engine oi l temperature to a mini ­
mum of 140
°F (60 °(). The tires also only
reach their full road holding capability once
they have warmed up .
The cooling fan can contin ue to run in your ve­
h icle after the engine is switched off. Howev­
er, driving the vehicle to cool it down is part ic­
ularly important. During sporty driving, the
engine and brakes, the ex ha ust system, and
the transm ission all become extremely hot.
B efore you park the vehicle, you shou ld drive it for a few miles/kilometers at
light load in
the low rpm range to allow it to cool down.
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 c:> page 190,
Fuel supply.
.. Never run the tank down all the way to emp­
ty .
.. Never put too much moto r oil in your engine
c:> page 199, 't::71 Adding engine oil .
.. Never try to p ush- or tow -sta rt yo ur vehicle.
The catalytic converter is an efficient "clean­
up" device bu ilt into the exhaust system of
t h e vehi cle. The cata lytic conve rter bu rns
many of the pollu tan ts i n t he exh aust gas be­
f ore they are re lease d into the atmosphere.
T he exclusive use of unleaded fue l is critica lly
impor tant for the life of the catalyt ic convert­
er and prope r fu nct ion ing of the engi ne.
8_ WARNING
- T he temperature of the exhaus t system
is high, both when driving and after stop ­
p ing the engine.
- Never touch the exhaus t tail pipes once
they have become hot . This cou ld result
in burns .
- Do not park or operate the vehicle i n
areas where the hot exha ust 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 additional undercoating or
rustproofing on or near the exhaust
manifold, exhaust pipes, catalytic con­
ver ter or heat shields . Dur ing driv ing, the
substance used for undercoating could
overheat and cause a fire.

id reservo ir
Before you check anything in the engine com­
partment,
a lwa ys re ad and heed all WARN·
ING S ¢.&._ in Working in the engine compart­
ment on page 195 .
.. Read the brake fluid level from the brake
fluid reservoir
¢ fig . 179 , ¢page 197,
fig . 174.
The brake fluid level must be be ­
tween the "MIN" and
"MAX" markings.
The brake fluid reservoir is located at the rear
partition of the engine compartment on the
left side
¢ page 197.
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
low the "MIN" mark, the brake warning/indi­
cator light (U.S. models:
11111 , 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 brake warn ing/
indicator light w ill illuminate. Contact an au­
thorized Audi dealer
immedi atel y.
@ Tips
The brake fluid reservoir is located under­
neath the cover.
Changing brake fluid
Have the brake fluid changed by an experi­
enced technician .
Brake fluid absorbs moisture from the air. If
the water content in the brake fluid is too
high, corrosion in the brake system may result
after a period of time . The boiling point of the
brake flu id will also decrease conside rably and
decrease braking pe rformance.
Therefore, the brake fluid must be changed
every two year s. Always use new brake flu id
which conforms to Federal Motor Veh icle
Standard "F MVSS 116 DOT 4".
The brake fluid reservoir can be diff icult to
reach, therefore, we recommend that you
have the brake fluid changed by your author­
ized
Audi d ealer . Your dealer has the correct
tools, the right brake fl uid and the know -how
to do this for you .
A WARNING
- Brake fluid is poisonous . It must be stor­
ed only in the closed original container
out of the reach of children!
- Brake failure can resu lt from o ld or inap­
propriate brake flu id. Observe these pre­
cautions:
- Use only brake f luid that meets SA E
specifica tion
J 1 7 03 and conforms to
Federa l Moto r Ve hicle Standard 1 16.
Always check with yo ur authorized Aud i
dealer to make sure yo u are using the
correct brake fluid. The correct type of brake f lu id is also indicated on the
brake fluid reservoir.
- The brake fluid must be new. Heavy use
of the brakes can cause a vapor lock if
the brake fluid is left in the system too
l ong. This can seriously affect the effi­
c iency of the brakes as well as your
safety. This cou ld resu lt in an accident.
(D Note
Brake fluid will damage the paint of your
vehicle .
