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.
- 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.
Airbag system 163
-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.
- Work on the pyrotechnic circuit inter­
rupter must only be performed by a
qualified technicians who have the ex­
perience, information and special tools
necessary to perform the work safely.
- If the vehicle or the circuit interrupter
is scrapped, all applicable safety pre­
cautions must be followed.
@) For the sake of the environment
Undeployed airbag modules and preten­
sioners might be classified as Perchlorate
Material - special handling may apply, see

(D Note
-Be aware that just one tank fi lling with
le aded fuel will already seriously de­
grade the performance of the catalytic
converter.
- Do not exceed the correct engine oil leve l
c>page229.
-Do not drive until the fuel tank becomes
complete ly empty. The engine could mis ­
fire. Unburned fuel could also get into
the exhaust system and this could cause
the catalyt ic converter to overheat.
- Do not switch off the ignition wh ile the
vehicle is moving .
- Do not continue to operate your vehicle
under these condit ions, as otherwise fuel
can reach the catalytic converter. This
could result in overheat ing of the con­
verter, requ iring its replacement.
- To assure efficient operat ion of the Emis­
s ion Control System:
- Have your vehicle maintained properly
and in accordance with the service rec­
ommendations in your Warranty
&
Ma intenance booklet.
- Lack of proper maintenance as well as
improper use of the vehicle will impa ir
the funct ion of the emission control
system and could lead to damage .
@) For the sake of the environment
Even when the Emission Control System is
operating properly, the exhaust gas can
have a sulfur-like exhaust gas smell under
some operating states. This depends on
the s ulfur content of the fuel being used.
Using a d ifferent brand of fuel may help,
or filling the tank w it h lead-free super
grade gasoline .
Diesel particulate filter
Appl ies to vehicles : wit h diesel e ng in e
The diesel particulate filter fi lters nea rly a ll of
the soot part icles o ut o f the exhaus t. T he fi l­
ter cleans itse lf automatically under normal
driving conditions . If the fi lter cannot clean it-
Drivin g and en vironm ent 205
self (for example, because you are on ly driving
short distances), the fi lter becomes clogged
with soot and the
II symbol for the diese l
particulate filter illuminates
c> page 21.
A WARNING
-Do not park your veh icle over flammable
mate ria ls such as grass or leaves because
the high temperature of the diesel par­ ticulate fi lter could start a fire.
- Do not apply an underbody protectant in
the exhaust system area or a fi re could
start.
Shutting down vehicle
If you would like your vehicle to rema in inop ­
erative for a longer per iod of t i me, contact an
Audi o r other spec iali zed dealer. They can ad­
vise you on necessa ry precautions e.g. co rro­
s ion p reven tion, maintena nce and s torage.
Pay attention to additional information con ­
cerning the battery . Refer to
c> page 235 .
Operate your vehicle
economically and
minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex­
haust and noise levels.
Fuel economy, environmenta l impact, and
wear on your engine, brakes and tires largely
depend on three factors:
- your personal d riving s tyle
- operati ng conditions
- technical limitat ions
If you ant ic ipate what you need to do next and
drive economically, you can easily cut your
fuel consumpt io n by 10-15 percent . T his sec ­
tion w ill give you some tips on how you can
help the env ironment and your poc ketbook. ..,_ •

238 Check ing and filling
cracked an d weake ned when the battery
froze.
- Charge the battery in a we ll ventilated
area. Keep away from open flame or elec­
trical spark. Do not smoke. Hydrogen gas
generated by 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 technician w ith the proper equip­
ment.
- Battery acid that may spill during charg­
ing should be washed off w ith a solution
of warm water and baki ng soda to neu­
t rali ze the acid.
~ Note
Never use a fast charger as a booster to
start the engine. This will seriously dam­
age sensitive el ect ronic components, such
as co ntrol units, relays, rad io, etc., as we ll
as th e batte ry charge r.
Battery replacement
The new battery must have the same specifi­
cations and dimensions as the original equip­
ment battery.
I ntell igent energy management in your vehi­
cle is respo nsible for d ist ributing the electr i­
cal energy throughou t you r vehi cle
~ page 201. The inte lligen t energy manage­
ment system w ill keep the engine battery
charged better than vehicles without t his 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 manu­
facture only (the same as those installed at
the t ime your vehicle was delivered). Specifi­
cations a re listed on the battery hous ing. You r
author ized de aler m ust code the battery in
the energy management system to enable yo u
to use the energy managemen t fu nctions co r­
rectly after replacing the battery. T
he new battery must have the same capacity,
vo ltage ( 12-volts), amperage, construction
and plug sealing.
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
Make 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 .
- Ve hicles 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
t he same specifications as the o rigi 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.
