-Have the airbag system inspected by
your Audi dealer before transporting
anyone on the front passenger seat.
(D Tips
If the capacitive passenger detection sys­
tem determines that the front passenger seat is empty, the frontal airbag on the
passenger side will be turned off, and the
PASSENGER AIR BAG OFF light will stay
on .
Repair, care and disposal of the airbags
Parts of the airbag system are installed at
many different places on your Audi. Installing,
removing, servicing or repairing a part in an
area of the vehicle can damage a part of an
airbag system and prevent that system from
working properly in a collision.
There are some important things you have to know to make sure that the effectiveness of
the system will not be impaired and that dis­
carded components do not cause injury or pol­
lute the environment.
A WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal in­
jury and death by preventing an airbag from deploying when needed or deploying
an airbag unexpectedly:
- Never cover, obstruct, or change the
steering wheel horn pad or airbag cover
or the instrument panel or modify them
in any way .
- Never attach any objects such as cup
holders or telephone mountings to the
surfaces covering the airbag units.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one
moistened 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 de­
ploy and protect properly.
Airbag system 163
- Never repair, adjust, or change any parts
of the airbag system.
- All work on the steering wheel, instru­
ment panel, front seats or electrical sys­
tem (including 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
authorized Audi dealer or qualified work­
shop.
- 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 replace­
ment upholstery over the front seat­
backs that have not been specifically
approved by Audi.
- Never use additional seat cushions that
cover the areas where the side airbags
inflate.
- Damage to the original seat covers or
to the seam in the area of the side air­
bag module must always be repaired
immediately by an authorized Audi
dealer.
- The airbag system can deploy only once .
After an airbag has been deployed, it
must be replaced with new replacement
parts designed and approved especially
for your Audi model version. Replace­ ment of complete airbag systems or air­
bag components must be performed by
qualified workshops only. Make sure that
any airbag service action is entered in
your Audi Warranty
& Maintenance book­
let under
AIRBAG REPLACEMENT RE­
CORD .
-For safety reasons in severe accidents,
the alternator and starter are separated
from the vehicle battery with a pyrotech­
nic circuit interrupter.

238 Check ing and filling
- Char ge the bat tery i n a we ll ven tilated
area. Kee p away from open flame or elec­
trical spa rk. Do n ot smoke. Hydrogen gas
generated b y the battery is explosive.
- To reduce the danger of explosion, never
connect or disconnect charger cables
wh ile the charger is operating.
- Fast charg ing a battery is dangerous and
should only be attempted by a compe­
tent technicia n w ith the proper equ ip­
ment.
- Battery acid that may spill during charg­ ing should be washed off wit h a solution
of warm water and baking soda to neu­
t rali ze the acid.
(D Note
Never use a fast charger as a booster to
start the engine. This will se riously dam­
age sensitive elect ronic components, such
as control units, relays, rad io, etc., as we ll
as t he battery charger.
Battery replacement
The new battery must have the same specifi­
c ations and dimensions as the original equip­
ment battery.
Intell igent energy management in your veh i­
cle is respons ible for d istributing the e lectr i­
cal energy throughou t your vehicle
qpage 199. The intel ligen t energy manage­
ment system w ill keep the engine battery
charged better than vehicles without th is sys­
tem. To make sure the additional electrical en­
ergy is available once again after you have
changed the battery, we recommend that you
install batteries of the same type and ma nu­
facture only (the same as those installed at
the time your vehicle was delivered). Specifi­
cations a re listed on the battery ho using. Yo ur
author ized de aler must code the b attery in
the energy management system to enable you
to use the energy management fu nctions cor­
rectly after replacing the battery. T
he new battery must have the same capacity,
vo ltage ( 12-volts), amperage, construction
and plug sea ling.
When ins tall ing t he battery, make su re the ig­
nition and a ll elect rical consume rs are switch ­
ed off.
(D Note
M ake sure the ven tilat ion hose on the side
of the ba ttery is connecte d, otherwise
fumes or batte ry acid can lea k out .
- Veh icles with the Start-S top-System * are
equip ped with a spec ial cycle-proof AGM
battery . Install ing a d iffe rent type of
battery can cause problems in the vehi­
cle e lectr ica l system. Whe n replac ing the
vehicle battery, always install one w ith
the same specifications as the origi na l
battery.
@) For the sake of the environment
Because of the prob lem of proper disposal
of a battery, we recomme nd your author­
i zed Audi dealer change the battery fo r
you. Batteri es contain sulfur ic acid and
l ead and must a lways be di spo sed o f prop­
erly in comp liance wi th all envi ronmental
regulations. Disposing of vehi cle batter ies
imprope rly is very dange rous to the envi­
r onment.
