8_ WARNING
-Brake fluid is poiso nous. It must be sto r­
ed only in th e closed original container
out o f the reach of children!
- Brake fa ilure can result from old or inap­
propriate brake fluid. Observe these pre­
caut ions:
- Use only brake fluid that meets SAE specification
J 1703 and conforms to
Federal Motor Vehicle Standard 116.
Always check with your authorized Audi
dealer to make sure you are using the
correct brake flu id. The correct type of
brake fluid is also indicated on the
b rake 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
l ong. This can serious ly affect the effi­
ciency of the bra kes as well as yo ur
safety . This could result in an acc ident.
@ Note
Brake flu id will damage the paint of your
veh icle.
@i For the sake of the environment
Because of the problem of proper d isposa l
of brake flu id as we ll as the special tools
requ ired and the ne cessary expert ise, we
recommend that you have the brake fluid
changed by your author ized Audi dealer .
Battery
General information
The battery in your Audi does not need any
maintena nce under
normal operating condi­
tions. Aud i recommends having the elect ro­
l yte level check by a n author ized Audi dealer
or author ized Audi Se rv ice Facili ty when there
are
high outside temperat ures or when driving
all day. The e lectrolyte level shou ld a lso be
checked each time the battery is charged
¢ page 230.
Have the batte ry checked when yo u bring your
vehicle in for an inspection . It is a good idea
to replace the battery if it is more than 5 years
o ld.
D uring certain types of airbag deployments,
the battery is disconnected from the vehicle electrical system for safety reasons¢
& in
Repair, care and disposal of the airbags on
page 160.
Di sconnecting the battery te rminals
Some vehicle functions (such as power win ­
dows) are not avai lable when the battery is
disconnected. These functions must be pro­
grammed after the battery is reconnected. To
avo id hav ing to do this, only disconnect the
battery from the vehicle electrical system
when that is necessary to perform repairs .
To reprogram the functions, proceed as fol­
lows:
Function Reprogramming
Power window one-¢ page 44, Correcting
touch up/down power window ma/-
function functions
Remote control key
If the vehicle does not
or r
eact to the key, it
convenience key must be synchronized
¢ page37
Dig ita l cl ock ¢page 10
ESC indicator light The indicator light
goes out after driving
a few meters
Not running the vehicle for long periods
of time
If you do not drive your vehicle fo r several
days or weeks, electrical components are
gradua lly reduced or switched off. This re­
duces e nergy consumption and maintains the
vehicle's ability to start over a long per iod of
time
¢ page 194. Some convenie nce func­
tions, such as interior lig hting or power seats *
may not work. These convenience functions
will be ava ilable again once you switch the ig-
nition on and start the engine. .,.

Winter operati on
During the winter months, it is common for
the battery capacity to decrease as the tem ­
peratures become lower. This is because more
pow er is n eeded to start the vehicle and com­
ponents such as the headlights and the rear
window defogger are used more frequently.
Avoid using power unnecessarily, especially in
city driving or on short trips . Have your a u­
thorized Audi dealer or authorized Audi Serv­
ice Facility check the battery capac ity before
the start of winter ¢
page 230 . A well-charg­
ed battery will not only reduce starting prob ­
l ems in cold weather, but it wi ll also last lon­
ge r.
A WARNING
- Wor k on the battery requires expert
knowledge. Con tact your au thori zed Audi
dealer q ua lified repai r fac ility for infor ­
mation regarding the vehicle battery.
The re is a risk for chemical burns or ex­
plos ions.
- Never open the vehicle battery. Do not
try to change the battery e lectrolyte lev ­
el. Otherwise explosive gas will escape
from the battery and increase the risk of an exp losion .
@ Tips
If your vehicle is not driven for severa l
weeks in very cold temperatures, remove
the battery and store it in a place where it
w ill no t freeze . This prevents the battery
from being damaged and need ing to be re­
placed.
Working on the battery
Be especially careful when working on or near the battery .
The battery is located in the lugg age compart­
ment under the floor. Before you check any -

230 Checking and Filling
-Do not expose the battery to an open
flame, electric sparks or an open light.
- Do not smoke.
- Do not interchange the positive and neg-
ative cables.
- When working on the battery, be sure
not to short-circuit the terminals with
tools or other metal objects. This would
cause the battery to heat up very quickly,
which could lead to damage or explosion
and personal injury.
- When a battery is charged, it produces
hydrogen 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 ca­ ble.
- Before performing any work on the elec­
trical system, switch off the engine and ignition as well as any electrical equip ­
ment . The negative cable on the battery
must be disconnected . If you are just go­
ing 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! Other­
wise you will set off the alarm.
- When disconnecting the battery, first
disconnect the negative cable and then
the positive cable .
- Before reconnecting the battery, make
sure all electrical consumers are switch­
ed off. Reconnect the positive cable first
and then the negative cable. Never inter­
change 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 dead battery can free ze over at 32°F (O°C).
- Make sure the vent hose is always attach­
ed to the opening on the side of the bat­
tery.
- Never use batteries which are damaged.
There is the danger of an explosion! Al­
ways replace a damaged battery . A WARNING
-California Proposition 65 Warning:
- Battery posts, terminals and related ac­
cessories contain lead and lead com­
pounds, chemicals known to the State of
California to cause cancer and reproduc­
tive problems . Wash hands after han­
dling.
(D Note
- Do not disconnect the vehicle battery
when the ignition is on or when the en ­
gine is running, otherwise, you will dam­
age electronic components in the electri­
cal system.
- If your vehicle is going to stand for a
long period of time without being driven,
protect the battery from "freezing", oth­
erwise it will be damaged and will then
have to be replaced.

tery to thaw completely before attempt ing to
charge it
c:> &. . However, we recommend not
using a thawed battery again because the bat­
tery cas ing can be cracked due to ice forma­
tion and can leak battery acid.
B atter y ch arging (Ma ximum charging rate
of
30 amps / 14.8 Volt)
When cha rging at low voltages (e .g. w ith a
tric kle charger ), the battery cables do not
have to be d isconnected first. The batte ry
caps sho uld
not be opened when charging a
battery .
It is not necessary to remove the batte ry from
the luggage compa rtment, and it is also not
necessa ry to disconnec t the cables.
Fa st charging the b attery (charging rate
above
14.8 Volts )
For technica l reasons do not use a battery
charger that uses voltage g reate r than
14.8 Volts to charge your veh icle's battery.
WARNING
Charging a battery can be dangerous.
- Always fo llow the oper ating instructions
provided by the battery charge r manu­
fact urer when charging your battery.
Checking and Fillin g 231
-Never charge a frozen battery. It may ex­
plode because of gas trapped in the ice .
Allow a frozen battery to thaw out first.
- Do not reuse batteries wh ich were fro­
zen. The battery housing may have
cracked and weakened when the battery
froze.
- Charge the battery in a well ventilated
area. Keep away from open flame or elec­
trical spark. Do not smoke. Hydrogen gas
generated by the battery is explos ive.
- To reduce the danger of explosion, never connect or d isconnect charger cab les
while the charger is ope rat ing.
- Fast charging a batte ry is dangerous and
should only be attempted by a compe­
tent techn ic ian with the prope r equip­
ment.
- Battery acid that may spi ll dur ing cha rg­
ing should be washed off wi th a solut io n
of wa rm w ater and baking soda to neu­
trali ze the ac id.
(D Note
Neve r use a fast cha rger as a boost er to
star t the engine. This w ill ser iously dam­
age sens it ive e lectronic componen ts, su ch
as cont ro l units, re lays, radio, etc., as well
as the battery charger.
Battery replacement
The new battery must have the same specifi­
cations and dimensions as the original equip ­
ment battery.
Inte lligent energy management in your vehi­
cl e is responsible for dist ributing the elect ri­
ca l energy throughout yo ur vehicle
<=> page 194 . The intelligent energy manage­
ment system will keep the engine battery
charged better than vehicles without this sys­
tem . To make sure the additional electrical en­
ergy is ava ilab le once again after you have
changed the batte ry, we recommend that you
insta ll batteries of the same type and manu-
factu re on ly (the same as those installed at

the time your vehicle was delivered) . Specifi­
cations are listed on the battery housing. Yo ur
author ized dealer must code the battery in
the energy management system to enable you
to use the energy management functions cor­ rectly after replac ing the battery .
The new battery must have the same capacity,
voltage (12-volts), amperage, construct ion
and plug sealing.
When insta lling the battery, make sure the ig­
n ition and all e lectr ica l consumers are sw itch­
ed off.
Make sure the venti lation hose on the side
of the battery is connected, otherwise
fumes or battery ac id can leak out.
@ For the sake of the environment
Because of the problem of proper disposa l
of a battery, we recommend your author­
ized Audi dealer change the battery for
you. Batter ies contain su lfuric ac id and
