A WARNING
-Read and fo llow the warnings in
¢ page 330, Working in the engine com­
partment
befo re opening the hood and
checking the brake fluid level.
- If the brake system indicator light does not tur n off or it turns on wh ile driving, the
b rake fl uid leve l in the reservo ir is too low,
a nd this increases the risk of an accident.
S top the vehicle and do not contin ue d riv­
ing . See an authorized Aud i dealer o r au­
thorized A udi Service Facility for assistance.
-If the b rake system indi cator light turns on
together with the ABS and ESC indicato r
lights, the ABS/ESC regu lating function may
be malfunct ion ing. Funct ions that stabilize
the vehicle are no longer available. This
could cause the vehicle to swerve, which in­
creases the risk that the vehicle will slide. Do not cont inue drivi ng . See an autho rized

A WARNING
You should only switch sport mode on or switch ESC/ASR off if your driving abilities
and road conditions permit .
- The stabilization function is limited when
sport mode is sw itched on . T he driving
wheels co uld spin and the vehicle cou ld
swerve, espec ially on s lick o r sli ppery roa d
surf aces.
- T here is no vehicle stabilization when ESC/
ASR a re swi tched off .
Brakes
New brake pads
New brake pads do not ac hieve the ir full b raking
effect during the first 250 mi (400 km) . They
must be "broken
in " fi rst . However, you can com­
pensate for the slightly reduced bra king fo rce by
pr ess ing firmly o n the bra ke pe dal. Avoid heavy
b ra king dur ing t he b reak -in per io d .
Wear
Brake pad wear depends largely o n the way the
ve hicl e is driven and on operat ing cond it ions .
This is especially t rue if you are d riving freque ntly
in t he c ity and on curves o r wi th a sporty driving
s tyle.
Operating noise
Noises may occur when braking depend ing o n the
speed , braking force and ou ts ide cond it ions such
as te m pe ra ture and humi dity .
Wet conditions or road salt
In certain situations, for example after driving
through water, in heavy ra in or after washing
your car, the braking ef fect may be reduced due
to mo isture or ice on the b rake roto rs and b rake
pads. The b rakes mus t be
"dried" firs t wi th a few
care ful bra ke app lic at ions.
At higher speeds and with t he windsh ie ld wipers
turned o n, the brake pads press against the bra ke
rotors for a s ho rt amoun t of time. This ac tion,
whi ch is not felt by the driver , happens at regul ar
i nte rvals an d ens ures a better reac tion time fo r
the brakes in wet weat her.
Intellig ent Technology
The brak ing effec t can a lso be reduced if yo u are
driving on salted roads and yo u do not app ly the
bra kes for long per iods o f time. The layer of sa lt
on the brake rotors and pads m ust be worn off
first whe n the brakes are applied .
Corrosion
Leaving t he vehi cle pa rked for long periods o f
time, low mileage and avoiding heavy b raking
can contrib ute to corros ion on the b rake roto rs
and to dirty brake pads.
If you usu a lly avoid heavy bra king or if there is
cor rosion prese nt, occasiona l heavy braking at
high speeds is recommended to clean the brake
roto rs and pads
c> ,& .
Brake system malfunction
If you notice that the bra ke pedal trave l has sud ­
denly in crease d, then a brake circuit in the dua l­
circuit b rake system may have malfunctioned.
Drive to an authorized A udi dealer or authorized
Audi Se rvice Facility immed iate ly to have the
problem corrected. On the way there, d rive w ith
reduced speed and keep in mind that you will
need a longer distance to stop and you will need
to press the bra ke ped al ha rder.
Low brake fluid level
When the bra ke fluid level is low, malfu nctions in
the b rake system may occur . T h e brake fluid level
is e lec tron ically moni tored.
Brake booster
The brake booster ampli fies t he p ressure you ap­
ply to the brake pedal.
A WARNING
- On ly app ly the brakes for the purpose of
cleaning the brake system when road and
traffic cond itions permi t. You must not en ­
da nger other road users. This inc reases the
ris k of an a ccid en t.
- Never let the vehicle roll while the engine is
sto pped bec ause t his increases the risk of an
a ccident.

Engine oil
Engine oil specifications
The engine oil used must conform to exact speci ­
fications.
The serv ice interval d isplay i n the instrumen t
clus ter o f your veh icle will inform you when it is
time for an o il change . We recommend that you
have your oi l changed by an author ized Audi Serv-
ice Advisor.
..,_

.. Place a cloth over the coolant expansion tank
cap .
.. Push the release button ¢ fig. 2 78 and careful­
ly unscrew the cap to the left until you feel re­
sistance¢ &_ .
.. Push the release button again and remove the
cap completely .
.. Make sure that the fluid level remains stable .
Add more coolant if necessary .
.,. Turn the cap to the right to secure it until yo u
feel resistance a second time.
Coolant loss usually indicates there is a leak . Im­
mediately drive your vehicle to an authorized
Audi dealer or authorized Aud i Serv ice Facility
and have the cooling system inspected. If the
cooling system is not leaking, a loss can come
from the coolant boiling through overheating
and being pushed out of the cooling system.
A WARNING
- The cooling system is under pressure. Do
not open the coolant expansion tank cap
when the engine is hot. This increases the
risk of burns .
-The coolant additive and the coolant can be
dangerous to your health . For this reason,
keep the coolant in the original container
and away from children. There is a risk of
poisoning.
-When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of injury.
CD Note
Do not add coolant if the expansion tank is
empty. There may be air i n the cooling sys­
tem, which increases the risk of engine dam­
age . If this is the case, do not continue driv­
ing . See an authorized Audi dea ler or author­
ized Aud i Service Facility for assistance.
Checking and Filling
Brake fluid
Fig. 279 E ng in e compartment : cap on brake fluid reservo ir
Observe the safety precautions ¢&. in Working
in the engine compartment on page 330 .
Checking the brake fluid level
... Read the brake fluid level on the brake fluid
reservoir¢ page 332, fig . 276 . The brake fluid
level must be between the MIN and MAX mark­
ings¢_.&. .
The brake fluid level is monitored automatically.
Changing the brake fluid
Have the brake fluid changed regularly by an au­
thorized Audi dealer or authorized Audi Service Facility.
A WARNING
- If the brake flu id level is below the MIN
marking, it can impair the brak ing effect
and driving safety, wh ich increase the risk of
an accident. Do not continue dr iving . See an
authorized Audi dealer or authorized Audi
Serv ice Facility for assistance.
-If the brake fluid is old, bubbles may form
in the brake system dur ing heavy braking.
This would impair braking performance and
driving safety, which increases the risk of an
accident.
-To ensure the brake system functions cor­
rectly, only use brake fluids that comp ly
with VW standard 501 14 or FMVSS-116 DOT 4.
CD Note
-If the brake flu id l eve l is above the MAX
marking, brake fluid may leak out over the
