A WARNING
You should only switch sport mode on or switch ESC/ASR off if your driving ab ilities and
road condit ions perm it.
- The stabilization function is limited when
sport mode is switched on. The dr iving
wheels could sp in and the veh icle could
swerve, especially on slick or slippery road
surfaces.
- There is no vehicle stabilization when ESC/
ASR are switched off.
(D Tips
- ESC/ASR cannot be switched off or sport
mode cannot be sw itched on if the cru ise
control system* or the adapt ive cruise con­
trol* is switched on.
- Malfunctions in the Audi magnetic r ide may
make it impossible to sw itch the ESC/ASR
off or to switch spo rt mode o n.
Brakes
New brake pads
New brake pads do not achieve their full braking
effect during the first 250 mi (400 km). They
must be "broken in" f irst. Howeve r, you can com­
pensate for the slightly reduced braking force by
press ing firmly on the b rake pedal. Avoid heavy
braking during the break -in period.
Wear
Brake pad wear is large ly dependent on the way
the veh icle is d riven and on operating co nditions.
This is especially t rue if you are driving frequent ly
in the city and on cu rves or with a sporty driving
style.
Operating noise
Noises may occur when braking depending on the
speed, b rak ing force and o utside conditions s uch
as tempe rat ure and h umid ity.
Effect of water and road s alt
In certain situat ions, for example after driving
throug h wate r, in heavy ra in, after overn ight con­
densat ion or afte r wash ing you r car, the braking
In te llig ent T echnolog y
effect can be reduced by moisture or ice on the
brake rotors and brake pads . The brakes must be
"dried" first with a few careful brake applications.
At higher speeds and with the windsh ield wipers
turned on, the brake pads press against the b rake
rotors for a short amount of time . This action
wh ich is not felt by the driver happens at regular
intervals and facilitates a better reaction t ime for
the brakes in wet weather.
The braking effect can a lso be reduced if you are
driv ing on salted roads and you do not apply the
brakes for long periods of time. The layer of salt
on the brake rotors and pads must be worn off
first whe n the brakes a re applied .
Corro sio n
Leav ing the ve hicle parked for long periods of
t ime, low mileage and avoiding heavy braking can
contribute to corros ion on the brake rotors and
dirty brake pads.
If you usua lly avoid heavy b raking or if there is
corrosion present, occas ional heavy braking at
high speeds is recommended to clean the brake
rotors and pads¢,&.
Brake sy stem malfunct ion
if you notice that the b rake pedal travel has sud­
denly gotten larger, then a brake circ uit may have
failed. Drive to an authorized Audi dealer or au ­
thori zed Audi Service Facility immediately to have
the problem cor rected. On the way there, dr ive
with reduced speed and keep in mind that a long
braking distance and increased pressu re on the
brake pedal will be necessa ry.
Low br ake fluid level
When the brake f lu id level is low, malfunct ions in
the brake system may occur. The brake flu id leve l
is electronically mon itored.
Brake boo ste r
The brake booster amplifies the pressure yo u ap­
ply to the brake peda l.
It only works when the en-
gine is running.

- the temperature of the engine coolant rises due to the heat bui ld-up from the eng ine in the en ­
gine compartment, or
- the engine compar tment heats up because the
vehicle is parked in intense sunlight.
A WARNING , --
- To reduce the risk of personal injury never
touch the radiator fan.
- The auxiliary e lectric fan is temperature con­
trolled and can switch on suddenly even

The fluid level may drop slightly after some time
due to the automatic adjustment of the brake
pads . This is not cause for a larm.
If the brake f luid leve l falls considerably below
the "MIN" mark, the brake warning/indicator
light
1111 (U.S. mode ls) I. (Canadian models)
will come on
~ page 17. Do not continue to oper­
ate the vehicle . The comp lete brake system
should be thoroughly checked by an authorized
Audi dealer or other qualified fac ility and the
cause corrected . If the brake flu id level is too low,
the brake warning/indicator light wi ll illuminate .
Contact an a uthorized Audi dea ler
immedi ate ly .
Changing brake fluid
Have the brake fluid changed by an experienced
technician.
Brake fluid absorbs moisture from the air. If the
water content in the brake flu id is too hig h, cor­
ros ion in the brake system may result after a per i­
od of t ime. The bo iling po int of the brake fluid
will a lso decrease cons iderab ly and decrease
braking performance.
Therefore, the brake fluid must be changed
e ve ry
tw o years .
Always use new brake flu id which co n­
forms to Federal Motor Vehicle Standard "FMVSS
116 DOT 4".
The brake fluid reservoir can be diff icu lt to reach,
therefore, we recommend tha t you have the
brake flu id changed by you r authorized
Audi
de aler.
Your dea le r has the correct tools, the
right brake fluid and the know-how to do this for
you .
A WARNING
- -
-Brake flu id is poisonous. It must be stored
only in the closed original conta iner out of
the reach of children !
- Brake failure can resu lt from o ld or inappro­
priate brake fluid. Observe these precau­
tions:
- Use only brake fluid that meets SA E spe ci­
ficat ion
J 1703 and conforms to Federa l
Motor Vehicle Standard 116. Always check
with your a uthorized Audi dea ler to make
~
207

Checking and F ill in g
sure you are using the correct brake f luid .
The correct type of brake fluid is also indi­
cated 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 long.
This can ser iously affect the effic iency of
the brakes as well as your safety . This
could res ult in an accident.
(D Note
Brake flu id will damage the paint of your vehi­
cle .
@ For the sake of the environment
Because of the problem of proper d isposa l of
brake fluid as well as the spec ia l tools re-
quired and the necessary expertise, we rec ­
ommend tha t you have the b rake fluid
changed by your author ized Audi dealer.
Battery
General information
The battery in yo ur Audi does not need any ma in­
tenance under normal operating conditions. Aud i
recommends having the electro lyte level check by
an author ized Audi dealer or author ized Audi
Service Fac ility when the re a re
high outside tem­
pe ratu res or when dr iv ing a ll day. The electroly te
leve l sho uld also be checked ea ch t ime the bat ­
t ery is charged
9 page 210 .
Have the battery checked when you br ing you r ve­
hicle in fo r an inspec tio n. It is a good idea to re­
p la ce the batte ry if i t is more than 5 ye ars old .
During certai n types of a irbag dep loyments, the
battery is disconnect ed from the vehicle electr i­
cal system fo r safety reasons
9 .&. in Repair, care
and disposal of the airbags on page 163.
Disconnecting the battery terminals
Some veh icle functions (such as power windows)
are not ava ilable when the batte ry is disco nnect­
ed. These functions must be programmed after
the ba ttery is reconnec ted. To avoid havi ng to do
t his , on ly disconnect the b attery from the veh icle
208
electrica l sys tem when that is necessa ry to pe r­
form repairs.
To reprogram the func tion s, proceed as fo llows:

Winter operation Du ring the winter months , it is common for the
batte ry capaci ty to dec rease as the tempe rat ur es
become lower . This is because more powe r is
needed to start the vehicle and componen ts such
as the he ad lights and the rear window defogger
are used more frequent ly.
Avoid using powe r unnecessar ily, especially in
c ity dr iv ing o r o n short trips . H ave yo ur au thor­
iz ed Audi de aler or author ized A udi Se rv ice Facili­
ty check the ba ttery capacity before the start of
winter ¢
