Before you check anything in the engine compart
ment,
always read and heed all WARNINGS
¢ A in Working in the engine compartment on
page 177.
., Read the brake fluid level from the brake fluid
reservoir
<=> fig . 153, ¢page 179, fig . 149 . The
brake fluid level must be between the
" MIN"
and "MAX " markings.
The brake fluid reservoir is located at the rear
partition of the engine compartment on the left
side ¢
page 179 .
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 below
the ' 'MIN" mark, the brake warning/indicator
light (USA models:
1111 , Canada models:. )
will come on¢
page 13 . Do not continue to oper
ate the vehicle . The complete brake system
should be thoroughly checked by an authorized
Aud i dealer or qualified workshop and the cause
corrected. If the brake fluid level is too low, the
brake warning/indicator light w ill illuminate.
Contact an author ized Audi dealer
immediately.
(D} Tips
The brake fluid reservoir is located under
neath the cover.

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 fluid is too high, cor
rosion in the brake system may result after ape
riod of time . The boiling po int of the brake fluid
will a lso decrease considerably and decrease
braking performance.
Therefore , the brake fluid must be changed
every
two years .
Always use new brake fluid which con
forms to Feder-al Motor Vehicle Standard "FMVSS
116 DOT 4 ".
The brake fluid reservoir can be difficult to reach ,
therefore, we recommend that you have the
brake fluid changed by your author ized
Audi
dealer .
Your dealer has the correct tools, the
right brake fluid and the know-how to do this for
you.
A WARNING
- Brake fluid is poisonous. It must be stored
only in the closed original container out of
the reach of children!
- Brake fai lure can result from o ld or inappro
priate brake fluid. Observe these precau
tions:
- Use only brake fluid that meets SAE speci
fi cation
J 1703 and conforms to Federal
Motor Veh icle Standard 116. Always check
with your authorized Audi dealer to make
sure you are using the correct brake fluid .
The correct type of brake f luid 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 seriously affect the efficiency of
the brakes as well as your safety. This
could result in an accident.
(D Note
Brake fluid will damage the paint of your vehi-
cle .

@ For the sake of the environment
Because of the problem of proper disposal of
brake fluid as we ll as the special toots re
quired and the necessary expertise, we rec
ommend that you have the brake fluid
changed by your authorized Audi dealer .
Battery
General information
Under normal operating conditions, the battery
in your Audi does not need any maintenance.
With
high outside temperatures or long daily
drives we recommend that you have the electro
lyte level checked by an authorized Audi dealer or
qualified workshop. The electrolyte level should
also be checked each time the battery is charged
c> page 189.
Have the battery checked when you take your ve
hicle in for serv ice. You are well advised to re
place a battery t hat is older than 5 years.
With certain types of airbag deployment, the battery is disconnected from the vehicle electri
cal system for safety reasons
c> & in Repair, care
and disposal of the airbags on page 125 .
Disconnecting the battery terminals
Some vehicle functions (power window regula
tors, for example) are lost if the battery termi nals are disconnected. These functions have to be
relearned after the battery terminals are con
nected again. To prevent th is, the battery should
only be disconnected from the vehicle e lectr ica l
system when abso lutely necessary for repairs.
Vehicles not driven for long periods
If you do not drive your vehicle over a period of
several days or weeks, electrical components are
gradually cut back or sw itched off. This reduces
energy consumption and maintains starting ca
pability over a longer pe riod
c> page 157.
Some of the conven ience functions may not oper
ate, such as the interior lights or the power seat
adjustment. The convenience functions will be
available again when you turn on the ignition and
start the engine.
Checking and Filling
Winter operation
During the winter months, battery capacity tends
to decrease as temperatures drop . This is be
cause more power is also consumed while start
ing, and the headlights, rear window defogger,
etc., are used more often.
Avo id unnecessary power consumption, particu
larly in city traffic or when traveling only short
distances . Let your authorized Audi dealer check
the capacity of the vehicle battery before winter
sets in
c> page 189. A well charged battery will
not only prevent starting problems when the
weather is cold, but will also last longer .
(D Tips
If your vehicle is left standing for several
weeks at extremely low temperatures, the ve
hicle battery should be removed and stored
where it w ill not freeze. This will prevent it
from be ing damaged and having to be re
placed.
Working on the battery
Be especially careful when working on or near
the battery.
The battery is located in the engine compart
ment . Before you check anything in the engine
compartment ,
read and heed all WARNINGS
c>,& ,
Always heed the safety warnings, when working
on the vehicle battery or the veh icle electrical
system to prevent injury.
The following WARNINGS are very important
when working on the battery:
Always heed the following WARNING SYM·
BOLS and safety precautions when working on
the battery.

Bulbs
Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for
you .
It is becoming increasingly more and more diffi
cult to replace vehicle light bulbs since in many
cases, other parts of the car m ust first be re
moved before you are able to get to the bulb .
T his applies especially to the light bulbs in the
front of your car which you can only reach
through the engine compartment .
Sheet metal and bu lb holders can have sharp
edges that can cause serious cuts, pa rts must be
correctly taken apart and then properly put back
together to help prevent breakage o f parts and
long term damage from water that can enter
housings that have not been properly resealed.
For your safety, we recommend t hat you have
your authorized Aud i dea le r rep lace any bulbs fo r
you, since your dealer has the proper tools, the
correct bulbs and the expertise.
Gas di schar ge la mps (Xe no n light s):
Due to the high electr ical voltage, have the bulbs
rep laced by a qualified technician. Headlights
with Xenon light are identified by the hig h volt
age st icker.
LED headlights* require no maintenance . Please
contact your authorized Audi dea ler if a bulb
needs to be replaced.
_&. WARNING
Changing Xenon lamps wi thout the necessary
equipment can cause serious personal injury .
- Bulbs are pressu rized and can explode when
be ing changed. Potent ial ris k of injury!
- On veh icles equipped with gas disc harge
bu lbs (Xenon light) life-threatening injuries
can resu lt from improper handling of the
high-vo ltage portions of such lamps!
- Only your authorized A udi dealer or quali
fied workshop sho uld change the bulbs in
