Checking and Filling
Brake fluid
Checking brake fluid level
The brake fluid level can be checked with a quick
glance.
Fig. 175 Engine compartment: Cover on the brake fluid
r eservoir
Before you check anything in the engine compart­
ment,
always read and heed all WARNINGS
¢ A in Working in the engine compartment on
page 193.
., Read the brake fluid level from the brake fluid
reservoir
<=> fig . 175, ¢page 195, fig . 171 . 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 195.
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 (U .S. models:
1111 , Canadian models: 1111)
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.
202
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 f luid .
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
¢ page 205.
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.
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 disco nnected 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 period¢
page 173.
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.
Winter operation
During the winter months, battery capacity tends
to decrease as temperatures drop . T his is be-
Checking and Filling
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 traff ic or when traveling only short
distances . Let your authorized Audi dealer check
the capacity of the vehicle battery before winter
sets in ¢
page 205. 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 luggage compart­
ment under the floo r. Before you check anything
in the luggage compartment,
read and heed all

medical attention immediately.
- Do not expose the battery to an open flame,
electric sparks or an open light .
- Do not smoke.
- Do not interchange the positive and nega-
tive cables .
- When working on the battery, be sure not to
short-circuit the terminals with tools or oth­
er metal objects. This would cause the bat­
tery to heat up very quickly, which could
lead to damage or explosion and personal
lnJUry.
- When a battery is charged, it produces hy­
drogen gas which is explosive and could
cause personal injury.
- Always keep the battery well out of the
reach of children.
- Before work is done on the electrical sys­
tem, disconnect the negative ground cable.
- Before performing any work on the electri­
cal system, switch off the engine and igni­
tion as well as any electrical equipment. The

Tires and vehicle load limits.
-The tire must flex more if the
tire pressure is too low or if
the vehicle speed or load are
too high. This heats the tire up
too much. This increases the
risk of an accident because it
can cause the tire to burst and
result in loss of vehicle con­
trol.
-Incorrect tire pressure in­
creases tire wear and has a
negative effect on driving and

creases the risk of an accident.
(D Note
Replace lost valve caps to re­
duce the risk of damage to the
tire valves.
@ For the sake of the environment
Tire pressure that is too low in­
creases fuel consumption.
(D Tips
Audi recommends using the
tire pressure specified for a normal load
q page 218 or for
a full load when the vehicle is
partially loaded .
Make sure that the tire designa­
tion on your tire matches the des­ ignation on the tire pressure label
and the tire pressure table.
The following table lists recom­
mended tire pressures in cold
tires according to the load and the size of the tires installed.

check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a signifi­
cantly under-inflated tire causes the tire to over­
heat and can lead to t ire failure. Under-inflation
a lso reduces fuel efficiency and tire tread life,
and may affect the vehicle 's handling and stop ­
p ing ability .
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsib ility to ma intain correct tire pressure,
even if under-inflation has not reached the level
to tr igger illum inat ion of the TPMS low tire p res­
sure telltale.
Your veh icle has also bee n eq uipped w ith a TPMS
malfunct ion indicator to indicate when the sys­
tem is not operat ing properly . The TPMS ma l­
function ind icator is combined w ith the low tire
p ressure tellta le. Whe n the system detects a
malfunct ion, the te lltale will flash fo r approx i­
mately one mi nute and then remain continuo usly
illuminated. This sequence will continue upon
subseq uent veh icle start-ups as long as the ma l­
function ex ists .
When t he malfunction indicator is ill uminated,
the system may not be ab le to detect or signal
l ow tire press ure as intended. TPMS ma lf u nctions
may occur for a var iety of reasons, including the
installation of replacement or alternate t ires or
wheels on the vehicle that prevent the TPMS
from functioning properly . Always c heck the
