Intelligent Technology
& WARNING
-New brake pads do not achieve their full
braking effect during the first 250 mi
(400 km). They must be "broken in" first .
However, you can compensate for the slight·
ly reduced braking force by pressing firmly
on the brake pedal. Avoid heavy braking dur·
ing the break-in period.
- Alway apply the brakes for the purpose of
cleaning the brake system when road and
traffic conditions permit. You must not en·
danger other road users. This increases the
risk of an accident.
- On steep slopes , reduce the speed and se­
lect a lower gear or lower selector lever po·
sition. Drive as little as possible while press· ing the brake pedal and avoid putting your
left foot on the brake pedal while driving.
This could cause the brakes to overheat and impair the efficiency of the brakes .
- Do not let the brakes "grind" by always
keeping your foot on the brake pedal. This
can cause the brakes to overheat, increase
wear and increase braking distance unneces·
sarily.
- Certain weather and operating conditions
such as driving through water, driving in
heavy rain or driving after washing your
ve·
hide can impair the effectiveness of the
brakes. In the winter, ice may build up on
the brake pads, rotors and drums. Check
these components by braking carefully. Ap·
plying the brakes carefully several times
dries the brakes and removes ice build-up .
- The efficiency of the brakes can also be im·
paired by driving for long stretches on roads
covered with salt without using the brakes.
You can
remove salt deposits from the brake
rotors and pads by carefully applying the
brakes several times.
- If the front spoiler is damaged or you install
another spoiler, make sure the front wheel
brakes are ventilated properly . Otherwise,
the brake system could overheat, which re·
duces their effectiveness.
- Failure of a brake circuit impairs braking
performance, which increases braking dis·
126
tance. Avoid driving the vehicle and have it
towed it to the nearest authorized Audi
dealer or authorized Audi Service Facility .
- Never let the vehicle roll while the engine is
stopped because this increases the risk of an
accident .
-If the brake booster is not working, you will
have to press much harder on the brake ped·
al to compensate for the lack of the booster .
(D Note
-Never let the brakes "rub" by pressing the
pedal lightly when braking is not really nee·
essary. This causes the brakes to overheat
and increases braking distance and causes
wear .
- Before driving on a long stretch with steep
slopes, reduce your speed and shift to the
next lower gear This makes use of the en·
gine braking effect and relieves the brakes .
If you need to brake additionally, brake in
intervals and not continuously.
(D Tips
-If the brake booster is not working, you
must press the brake pedal with much more
force then normal.
- If you retrofit your vehicle with a front spoil·
er, wheel covers or similar items, make sure
that the air flow to the front wheels is not
interrupted. Otherwise the brake system
can become too hot.
Electromechanical
steering
The electromechanical steering supports the
driver's steering movements .
Power steering adapts electronically based on
the vehicle speed.
T he vehicle still has full steering functionality if
the power steering fails or when the engine is
stopped (towing). To steer, you must apply much
more force than usual.

- 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

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:

If you do not d rive yo ur vehicle for several days or
weeks, e lectr ica l components are gradua lly re­
duced or switched off. Th is red uces energy con­
s u mption and maintains the vehicle's ability to
start over a long per iod of t ime ¢

gine.
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 ¢
page 210. A well-charged battery will
not only reduce starting problems in co ld weath­
er, but it will a lso last longer .

-If you have a flat tire, move a safe d istance
off the road. Turn off the eng ine, turn the
emergency flashers on and use other warn­
ing dev ices to alert other motor ists .
- Make sure that passengers wait in a safe
place away from the vehicle and well away
from the road and traffic.
- To help prevent the vehicle from moving
suddenly and possibly slipping
off the jack,
always fully set the parking brake and block
the wheel diagonally opposite the wheel be­ ing changed . When one front wheel is lifted
off the g round, placing the Automatic Trans­
miss ion in P (Pa rk) w ill
not prevent the veh i­
cle from moving .
- B efore you change a wheel, be sure the

.,. Use the wheel bolt wrench to t ighten all wheel
bolts firmly¢
page 243. Tighten them cross­
wise,
from one bolt to the (approx imately) op ­
pos ite one, to keep the wheel centered .
0 Note
When removing or installing the wheel, the
r im could hit the brake rotor and damage the
rotor. Work carefully and have a second per­
son help you.
@ Tips
Never use the hexagonal socket in the handle
of the screwdr iver to loosen or tighten the
wheel bolts.
- Pull the reversible blade from the screwdriv­
er before you use the hexagonal socket in
the handle to turn the wheel bolts.
Emergency assistance
-When mounting tires with unidirectional
tread design
make sure the tread pattern is
pointed the right way¢
page 245 .
-The wheel bolts shou ld be clean and easy to
t ur n. Check for dirt and corrosion on the
mating surfaces of both the wheel and the
hub. Remove all dirt from these surfaces be­
fore remounting the wheel.
Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the
right direction .
U sing a spare tire with a tread pattern
intended for use in a specific direction
When using a spare t ire with a tread pattern in­
tended for use in a specific direction, please note
the following:
- The direct ion of rotation is marked by an arrow
on the side of the tire.
- If the spare tire has to be insta lled in the incor­
rect direction, use the spare tire only tempora­
r ily since the tire w ill not be able to achieve its
optimum performance characteristics with re­
gard to aquaplaning, noise and wear .
- We recommend that you pay part icular atten­
tion to th is fact during wet weather and that
you adjust your speed to match road condi­
tions.
- Replace the flat tire with a new one and have it
installed on your veh icle as soon as possible to
restore the handling advantages of a unidirec­
tional tire.
Notes on wheel changing
Please read the information ¢ page 221 if you
are going to use a spare tire which is different
from the tires on your vehicle.
After yo u change a tire:
-Check the tire pressure on the spare immedi-
ately after installation.
