& WARNING (continued)
-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.
0 Note
Brake fluid will damage the paint of your vehicle.
W For the sake of the environment
Because of the problem of proper disposal of brake fluid as well as
the special tools required and the necessary expertise, we recom­
mend 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 it is
advisable however to check the fluid level at regular intervals
through the transparent battery housing. Also check the fluid level
each time you charge the battery. After charging the battery
~ page 289, you should likewise check the battery acid level.
Have the battery checked when you take your vehicle in for service.
You are well advised to replace a battery that is older than 5 years.
Preserving battery charge on a vehicle not operated
for a long time
Some components of the electrical equipment (for example, the
electronic immobilizer) will keep drawing a low current even when the car is
not running
. This will eventually drain the battery
completely if your vehicle is left sitting for a long period of time
without being driven . To prevent this, either charge the battery
occasionally or disconnect the battery negative (ground) cable.
Winter operation
During the winter months, battery capacity tends to decrease as
temperatures drop . This is because more power is also consumed
while starting, and the headlights, rear window defogger, etc., are
used more often.
Avoid unnecessary power consumpt ion, particularly 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 289. A well charged battery will not only prevent starting
problems when the weather is cold, but will also last longer.
[ i] Tips
If your vehicle is left standing for several weeks at extremely low
temperatures, the vehicle battery should be removed and stored
where it will not freeze. This will prevent it from being damaged and
having to be replaced. •
Location of the vehicle battery
The vehicle battery is located in the plenum chamber at the back of
the engine
compartment~ page 275.
The positive(+) battery terminal is protected by a plastic cover. This cover must be removed to access to the positive(+) terminal when
connecting jumper cables to start the engine .
& WARNING
Before you check anything in the engine compartment, always
read and heed all WARNINGS
~ & in "Working in the engine
compartment" on
page 273. •

battery to heat up very quickly , whi ch could le ad to damage or
explosion and personal injury .
• When a battery is charged , it produces hydrogen gas whi ch 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 system , disconnect the
negative ground cable .
• Before performing any work on the electri cal system , switch off
the engine and ignition as well as any electrical equipment. The negative cable on the battery must be disconnected. If you are just
going to replace a light bulb , then it is enough to switch off the
lights.
• Before disconnecting the battery, switch off the anti -theft
alarm system! Otherwise you will set off the alarm .
• When disconnecting the battery , fir st di sconnect the negative
c able and then the positive cable .
• Before reconnecting the battery, make sure all electrical
consumers are switched off . Reconnect the positive cable first and
then the negative cable. Never interchange the cables -this could
start a fire!
• Never charge a frozen or a thawed -out battery . It could
explode! If a battery has frozen, then it must be replaced . A
discharged battery can freeze over at 32 °F (0 °Cl.
• Make sure the vent hose is always attached to the opening on
the side of the battery.
• Never use batteries which are damaged . There is the danger of
an explosion! Always replace a damaged battery.

Checking the battery acid level on magic eye
batter ies
The battery acid level in the battery can be checked
through the clear inspection window.

co mpa rtme nt: B atte ry
w it h m agic eye
(battery cov er
r e m ove d)
On top of the battery, there is a round "window" . This
window (m agic eye) changes color as the battery cha rge
and acid level change .
- Read and heed all
WARN INGS=> & in "Working on the
battery" on
page 286
- Read the ac id level from the window on the battery
=> page 288, fig. 214.
Air bubbles in the window can cause an inaccurate reading . Care­
ful ly tap on the side of the window .
• If the window is
gre e n, the battery acid level is correct .
• I f the window has
no c olor or is bright y ello w, the battery acid
level is too low . Have the battery tested by your authori zed Audi
dea ler or a qualified workshop. •
If the window is
blac k, then the battery is insufficiently charged .
Recharge the battery as soon as possible
=> page 289 .
Under normal opera ting conditions, the battery in your Audi does
not need any maintenance.
At high outside temperatures it is advisable to check the battery acid level at regular intervals through the transparent battery
housing . Also check the acid level each time you charge the battery.
We recommend you have your authorized Audi dea ler test your
battery.
A battery that is older than five years and has a low acid level should
be rep laced.
0 Not e
Do not overfill the battery , otherwise battery acid will overflow
t hrough the vent opening. This can damage the paint and cause
corrosion .•

The recommended tire pressures for your Audi depend on the kind
of tires on your vehicle and the number of passengers and/or
amount of luggage you will be transporting.
The tire pressure label located either on driver's side 8-pillar or
inside the fuel filler flap on your Audi lists the recommended cold
tire inflation pressures for the vehicle at its maximum capacity
weight and tires that were on your vehicle at the time it was manu­
fac tured .
If you wish to improve comfort when operating the vehicle at
normal load (up to 3 occupants), you can adjust tire pressures to
those specified for normal vehicle load. Before operating the vehicle at maximum load, you must increase the tire pressures to those
specified for maximum vehicle load
~ & .
If your vehicle is equipped with a tire pressure monitoring system*,
bear in mind that the system can only monitor the tire pressures you have stored
. The system does not recognize the load condition of
your vehicle.
The effectiveness of the tire pressure monitoring system will be
impaired if you store normal load pressures but then operate the
vehicle at its maximum
load~& .
See the illustration~ page 297, fig . 217 for the location of the label
either on driver's side 8-pillar or inside the fuel filler flap (color of
the actual label and exact location on the vehicle will vary slightly).
Note that the following table is accurate at the time of going to
press and is subject to change . In the event of discrepancies, the tire
pressure label (e ither on driver's side 8 -pillar or inside the fuel filler
flap) always takes precedence.
The table below lists the recommended cold tire inflation pressures
for the Audi model covered by your Owner's Literature at the
vehicle's capacity weight and the tire si zes installed on the respec­
tive models as original equipment, or as a factory option.
