@ 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
WARNINGS ¢
LD.·
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.
®
Always wear eye protection.
A
Battery acid contains sulfuric acid. Al·
ways wear gloves and eye protection .

Check ing and F illing
CJ) Note
Never use a fast charger as a booster to start
the engine . This will serio us ly damage sensi­
tive electronic components, such as control
un its, relays, radio, etc., as well as the battery
charger .
Battery replacement
The new ba ttery mu st have the same specifica­
tions and dimensions as the original equipmen t
battery .
Intelligent energy management in your vehicle is
responsible for dist ributing the electrical energy
throughout your vehicle¢
page 173. The inte lli­
gent ene rgy ma nagement system wi ll keep the
eng ine batte ry charged better the n ve hicles w ith­
ou t th is system . To make su re the addit io nal
e lec trica l energy is avail ab le on ce again after you
h a ve changed the battery, we recommend t hat
you insta ll batteries o f the same type an d manu­
facture on ly (t he same as those insta lled at the
time your veh icle was delive red). Spec ificat ions
are listed on the battery housing. Your author­
ized Audi dealer must code the battery in the en­
ergy management system to enab le you to use
the energy manageme nt functions correctly after
replacing the battery .
If it is not possible to use a battery of th is type,
the new battery must have the same capacity ,
voltage (12-volts) , ampe rage, construct ion and
p lug sealing.
When insta lling the battery, make sure the igni­
tion and all electrical consumers are tur ned off .
@ Note
Make sure the ventilation hose on the side of
the batte ry is connected, othe rw ise fumes or
battery acid can lea k out.
@ For the sake of the environment
Because of the prob lem of proper disposal of
a battery, we recommend your author ized
Audi dea le r change the battery fo r you. Bat­
t er ies con ta in su lf ur ic ac id a nd lead a nd must
always be disposed of prop erly i n comp lianc e
206
with a ll environmenta l re gu lations . Disposing
of veh icle batteries im properly is very danger­
ous to t he environment.

Emergency situations
Emergency situations
General
This chapter is intended for trained emergency crews and working personnel who have the nec­
essary tools and equipment to perform these
operations.
Starting by pushing or
towing
(D Note
Vehicles with an automatic transmission
cannot be started by pushing or towing.
Starting with jumper
cables
If necessary, the engine con be started by con­
necting it to the battery of another vehicle .
If the engine should fail to start because of a dis­
charged or weak battery, the battery can be con­
nected to the battery of
another vehicle, using a
pair of jumper cables to start the engine.
Jumper cables
Use only jumper cables of sufficiently largecross
section
to carry the starter current safely. Refer
to the manufacturer's specifications.
Use only jumper cables with
insulated terminal
clamps which are distinctly marked :
plus(+) cable in most cases colored red
minus(-) cable
in most cases colored black .
A WARNING
Batteries contain electricity, acid, and gas.
Any of these can cause very serious or fatal in­
jury. Follow the instructions below for
safe
handling of your vehicle's battery .
-Always shield your eyes and avoid leaning
over the battery whenever possible.
-A dead battery can freeze at temperatures
around 32 °F (0 °C) . If the vehicle battery is
frozen, you must thaw it before connecting
the jump start cables.
If you do not, this in-
238
creases the risk of an explosion and chemi­
cal burns. After jump starting the vehicle,
drive to an authorized Audi dealer or author­
ized Audi Service Facility immediately to
have the vehicle battery checked.
- Do not allow battery acid to contact eyes or
skin . Flush any contacted area with water
immediately.
- Improper use of a booster battery to start a
vehicle may cause an explosion .
- Vehicle batteries generate explosive gases.
Keep sparks, flame and lighted cigarettes
away from batteries.
- Do not try to jump start any vehicle with a
low acid level in the battery .
- The voltage of the booster battery must also
have a 12 -Volt rating . The capacity (Ah) of
the booster battery should not be lower
than that of the discharged battery. Use of
batteries of different voltage or substantial­
ly different "Ah" rating may cause an explo­
sion and personal injury.
- Never charge a frozen battery. Gas trapped
in the ice may cause an explosion.
- Never charge or use a battery that has been
frozen . The battery case may have be weak­
ened.
- Use of batteries of different voltage or sub­
stantially different capacity (Ah) rating may
cause an explosion and injury. The capacity (Ah) of the booster battery should not be
lower than that of the discharged battery.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS
r=> poge 193.
([) Note
-Applying a higher voltage booster battery
will cause expensive damage to sensitive electronic components, such as control
units, relays, radio, etc.
- There must be no electrical contact between
the vehicles as otherwise current could al­
ready start to flow as soon as the positive
(+) terminals are connected .
