A WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal injury
and death by preventing an airbag from de­
ploying when needed or deploying an airbag
unexpectedly:
- 1
-Never cover, obstruct, or change the steer­
ing wheel horn pad or airbag cover or the in­
strument panel or modify them in any way.
- Never
attach any objects such as cup holders
or telephone mountings to the surfaces cov­
ering
the airbag units.
- For cleaning
the horn pad or instrument
panel, use only a soft, dry cloth or one mois­
tened with plain water. Solvents or cleaners
could damage the airbag cover or change
the stiffness or strength of the material so
that the airbag cannot deploy and protect
properly.
- Never repair,
adjust, or change any parts of
the airbag system.
-All work on the steering wheel, instrument
panel, front seats or electrical system (in­
cluding
the installation of audio equipment,
cellular telephones and CB radios, etc.)
must be performed by a qualified technician
who has the training and special equipment
necessary.
- For any work on
the airbag system, we
strongly recommend that you see your au­
thorized Audi dealer or qualified workshop.
- Never modify
the front bumper or parts of
the vehicle body.
- Always
make sure that the side airbag can
inflate without interference:
- Never install
seat covers or replacement
upholstery over the front seatbacks that
have not been specifically approved by
Audi.
- Never
use additional seat cushions that
cover the areas where the side airbags in­
flate.
Airbag system
-Damage to the original seat covers or to
the seam in the area of the side airbag
module must always be repaired immedi­
ately by an authorized Audi dealer.
-The airbag system can deploy only once. Af­
ter an airbag has been deployed, it must be
replaced with new replacement parts de­
signed and approved especially for your
Audi
model version. Replacement of com­
plete airbag systems or airbag components
must be performed by qualified workshops
only. Make sure that any airbag service ac­
tion is
entered in your Audi Warranty &
Maintenance booklet under AIRBAG RE­
PLACEMENT RECORD.
-For safety reasons in severe accidents, the
alternator and starter are separated from
the vehicle battery with a pyrotechnic circuit
interrupter.
-Work on the pyrotechnic circuit interrupt­
er must only be performed by a qualified
technicians who have
the experience, in­
formation and special tools necessary to
perform the work safely.
-
If the vehicle or the circuit interrupter is
scrapped, all applicable safety precautions
must be followed.
@ For the sake of the environment
Undeployed airbag modules and pretension­
ers might be classified as Perchlorate Materi­
al -special handling may apply, see
www.dtsc.ca.gov/hazardouswaste/perchlo­
rate. When the vehicle or parts of the re­
straint system including airbag modules and
safety belts with pretensioners are scrapped,
all applicable laws and regulations must be
observed. Your authorized Audi dealer is fa­
miliar
with these requirements and we recom­
mend that you have your dealer perform this
service for you.
Other things that can affect Advanced
Airbag performance

@ For the sake of the environment
Even when the Emission Control System is op­
erating properly, the exhaust gas can have a
sulfur-like
exhaust gas smell under some op­
erating states. This depends on the sulfur
content of the fuel being used. Using a differ­

Because of the problem of proper disposal of
brake fluid as well as the special tools re­
quired
and the ne cessary expertise, we rec­
ommend that you have the brake fluid
changed by your authorized Audi dealer.
Battery
General information
The battery in your Audi does not need any main­
tenance under normal operating conditions. Audi
recommends having the electrolyte level check
by an
authorized Audi dealer or authorized Audi
Service Facility
when there are high outside tem­
peratures or when driving all day. The electrolyte
level should also be checked each time the bat­
tery is charged ~page 247.
Have the battery checked when you bring your ve­
hicle
in for an inspection . It is a good idea to re­
place
the battery if it is more than S years old.
Sometimes when the airbags deploy, the battery
will be disconnected from the vehicle electrical
system for safety reasons ~.&in Repair, care
and disposal
of the airbags on page 203.
Disconnecting the battery
The battery should not be disconnected. Several
vehicle functions (power windows, for
example)
will be lost when the battery is disconnected. The
functions must be reprogrammed after connect­
ing the battery. To avo id this, the battery should
only be disconnected from the vehicle electrica l
system when it is absolutely necessary.
Not running the vehicle for long periods of
time
If you do not drive your vehicle for several days or
weeks, electrical consumers are gradually scaled
back
or switched off. This reduces energy use and
ensures the vehicle will be able to start after long
periods of time~ page 92. Some convenience
functions, su ch
as interior lighting or power seat
adjustment, may not be available under certain
circumstances. These convenience functions will
be available again once you switch
the ignition on
and start the engine.
Checking and Filling
Winter operation
A lot of stress is placed on the battery during
cold weather, which results in reduced starting
ability. Have the battery checked and recharged if
necessary
before the cold weather begins.
A WARNING
- Work on the battery requires expert know l­
edge. Contact an authorized Audi dealer or
authorized Audi Service Facility for informa­
tion regarding the vehicle battery. There is a
risk for chemical
burns or explosions.
- Never
open the vehicle battery. Do not try to
change the battery electrolyte level. Other­
wise explosive
gas will escape from the bat­
tery and increase the risk of an exp losion. ___ ....J
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 floor . Before you check anything
in the luggage compartment, read and heed all

around 32 QF (0 QC). A frozen or thawed out bat­
tery must no longer be used. The battery housing
could be cracked by
the formation of ice, which
could cause
battery acid to leak out¢& .
Battery charging (Maximum charging rate of
30 amps I 14.8 Volt)
When charging at low voltages (e.g. with a trick­
le charger ), the battery cables do not have to be
disconnected first. The battery caps should not
be opened when charging a battery.
Checking and Filling
It is not necessary to remove the battery from
the luggage compartment, and it is also not nec­
essary to disconnect the cables.
Fast charg ing the battery ( charging rate
above
14. 8 Volts)
For technical reasons do not use a battery charg­
er that uses voltage greater than 14.8 Volts to
charge your vehicle's battery.
A WARNING
!-='"
Charging a battery can be dangerous.
-Always follow the operating instructions
provided by
the battery charger manufactur­
er when charging your battery.
-Never charge a froze n battery. It may ex­
plode because of gas trapped in the ice. Al­
low a frozen battery to thaw out first.
-
Do not reuse batteries which were frozen.
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 electrical
spark.
Do not smoke. Hydrogen gas generat­
ed by the battery is explosive.
-
To reduce the danger of explosion, never
connect or disconnect charger cables while
the charger is operating.
-Fast charging a battery is dangerous and
should only be attempted by a competent
technician with the proper equipment.
-Batte ry ac id that may spill during charging
should be washed
off with a so lution of
warm water and baking soda to neutralize
t
he acid.
CD Note
Never use a fast charger as a booster to start
the engine. This will seriously damage sensi­
tive electronic components, such as control
units, relays, radio,
etc., as well as the battery
charger.
Tips
Only charge the battery through the connec­
tions in the engine compartment.

Battery replacement
The new battery must have the same specifica­
tions and dimensions as the original equipment
battery .
Intelligent energy management in your vehicle is
responsible for distributing the electrical energy
throughout your vehicle Q page 92. The intelli­
gent energy management system will keep the
engine battery charged better than vehicles with­
out this system. To make sure the additional
electrical energy is available once again after you
have
changed the battery, we recommend that
you install batteries of the same type and manu­
facture only (the same as those insta lled at the
time your vehicle was delivered). Specificat ions
are listed on the battery housing. Your author­
ized dealer must code the battery in the energy
management system to enable you to use the en­
ergy management functions correctly after re­
placing the battery.
The new
battery must have the same capacity,
voltage (12-volts) , amperage, construction and
plug sealing.
When installing the battery, make sure the igni­
tion and all electrical consumers are switched
off.
CD Note
Make
sure the ventilation hose on the side of
the battery is connected, otherwise fumes or
battery acid can leak out.
@ For the sake of the environment
Because
of the problem of proper disposal of
a battery, we recommend your authorized
Audi dealer change the battery for you. Bat­
teries contain sulfuric acid and lead and must
always be disposed of properly in compliance
with all
environmental regulations. Disposing
of vehicle batteries improperly is very danger­
ous to the environment.

CD Note
Vehicles with an automatic transmission can­
not be started by pushing or towi ng.
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 large cross
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 co lored 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 discharged
battery can freeze at tempera­
tures just below 32 °F (0 °C). Before con­
necting a jumper cable, you must thaw the
288
frozen battery completely, otherwise it
could explode.
-
Do not allow battery acid to contact eyes or
