160 Airbag system
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. -
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

can reach the catalytic converter . This
could result in overheating of the con­
verter, requ iring its replacement.
- To assure efficient operation of the Emis­
sion Control System :
- Have your veh icle ma inta ined properly
and in accordance with the service rec­
ommendations in your Wa rranty
&
Ma intenance booklet.
- Lac k of proper maintenance as well as
improper use of the vehicle will impa ir
t he funct ion of the emission control
system and cou ld lead to damage.
@) For the sake of the environment
Even when the Emission Cont ro l System is
operating properly, t he exhaus t gas can
have a s ulfu r-like exhaust gas smell unde r
some operating states. This depends on
the s ulfur content of the fue l being used .
Using a different brand of fuel may help,
or filling the tank w ith lead-free super
grade gasoline.
Diesel particulate filter
Applies to vehicles: with d iesel eng ine
The diesel particulate filter fi lters nearly a ll of
the soot part icles out of the exhaust. The fil­
ter cleans itse lf automatically under normal
driving conditions. If the filter cannot clea n it­
self (for examp le, because you are only driving
short d istances) , the fil ter becomes clogged
with soot and the
II symbo l for the diesel
particulate f ilter illum inates ~ page 23.
A WARNING
- Do not park yo ur vehicle ove r flammable
materials such as g rass or leaves because
the high temperature of the diesel par­
t icu late filter could start a fire .
- Do not apply an underbody protectant in
the exhaust system area or a fire could
start.

Placing your vehicle
out of service
If you would like to take your vehicle out of
se rv ice for a longer time, contact your author­
ized Audi dealer or qualified repair fac ility .
They w ill advise yo u of impo rtant measures,
such as corrosion p rotection , maintenance
and storage p roced ures. Also follow the infor­
ma tion about the battery ~ page 228 .
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, env ironme ntal impact, and
wea r on your eng ine, b rakes and tires la rgely
depend on three factors:
- your personal d riving s tyle
- operating 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 ion by 10-15 percent. This sec­
tion w ill give you some tips on how you can
help t he env ironment and your pocketbook.
@ Tips
The consumption estimates as published
by ENVIRONME NTAL PROTECTION AGENCY
(EPA) and Transpo rt Canada may not corre­
spond to your actual consumption on the r oad, which will va ry depending upon vehi ­
cle load and speed, ro ad and weather con­
ditions, trip leng th, etc.
Drive smoothly and keep a lookout
ahead

A discharged battery can freeze at tempera­
tures of on ly 32 F
0 (0 °C). A llow a frozen bat­
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
