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 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.

different tire speeds. For this rea­son, in case of emergency, only
use a spare tire that has the same
circumference as the regular
tires.
&_ WARNING -
-Only use tire/rim combina­ tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident could result.
-For technical reasons, it is not
possible to use tires from oth­
er vehicles - in some cases,
you cannot even use tires from
the same vehicle model.
-Make sure that the tires you
select have enough clearance
to the vehicle . Replacement
tires should not be chosen
simply based on the nominal
size, because tires with a dif­
ferent construction can differ
greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged and this can reduce driving
safety and increase the risk of
an accident.
Wheels
-Only use tires that are more
than 6 years old when abso­ lutely necessary and drive
carefully when doing so.
-Do not use run-flat tires on
your vehicle. Using them when
not permitted can lead to ve­
hicle damage or accidents.
- If you install wheel covers on
the vehicle, make sure they al­ low enough air circulation to
cool the brake system. If they
do not, this could increase the
risk of an accident.
Tire wear/damage

tor
Tire wear
Check the tires regularly for wear .
-Inflation pressure that is too low
or high can increase tire wear
considerably.
-Driving quickly through curves,
rapid acceleration and heavy
braking increase tire wear. ..

also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop­
ping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
sure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys­
tem is not operating properly. The TPMS mal­
function indicator is combined with the low tire
pressure telltale. When the system detects a
malfunct ion, the telltale will flash for approxi­
mately one minute and then remain continuous ly
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal­
function exists.
When the malfunction indicator is illuminated,
the system may not be ab le to detect or signal
low tire pressure as intended . TPM S malfunctions
may occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly . Always check the
TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.

If the Tire Pressure Monitoring System
indicator appears
Applies to vehicles : wi th tire pressure mo nito rin g sys te m
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction.
Fig. 160 Instrument cluster : indicator lig ht with message
Using the ABS sensors, the tire pressure monitor­
ing system compares the tire tread circumfer­
ence and vibration characterist ics of the ind ividu ­
al tires. If the pressure changes in one or more
t ire s, this is indicated in the instrument cluster
display with an indicator light
[I] and a message.
If only one tire is affected, the location of that
ti re will be indicated.
The tire pressures must be stored in the Infotain­
ment system again each time the pressures
change (switching between partial and full load
pressure) or after changing or replacing a tire on
your vehicle ~
page 210. The tire pressure moni­
toring system on ly monitors the tire pressure you
have stored. Refer to the tire pressure label for
the recommended tire pressure for your vehicle
