Repair, care and disposal of the airbags
Parts of the airbag sys tem are installed at
many different pla ces on your Audi. Installing,
removing, servicing or repairing a part in an
area of the vehicle can damage a part o f an
airbag system and prevent that system from
working properly in a co llision.
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 po l­
lute the env ironment.
A WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal in­
jury and death by preventing an airbag from deploy ing when needed or deploying
an airbag unexpected ly:
- Never cover, obstr uct, or change the
steering wheel horn pad or airbag cover
o r the instr ument pane l or modify them
in any way.
- Never attach any objects such as cup
holders or telephone mountings to the
su rfaces covering the airbag uni ts .
- For cleaning the ho rn pad or ins trumen t
pane l, use only a soft, dry cloth or one
moistened w ith plain water . Solvents or
cleaners co uld 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 stee ring wheel, instru­
ment pane l, front seats or electrical sys­
tem (including the installation of aud io
equipment, cellular telephones and CB
radios, etc.) must be performed by a
qualified technician who has the training
and special equipment necessa ry.
- For any wor k on the ai rbag system, we
st rongly recommend that you see you r
au thori zed Aud i dealer o r qualified wo rk­
s hop.

-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 upholste ry over the front seat­
backs that have not been specifically
approved by Audi.
- Never use additional seat c ushions that
cover the areas where the side a irbags
i nfla te.
- Damage to the orig inal seat cove rs or
to the seam in the area of the si de a ir­
bag module mus t always be repaired
immediately by an authorized Audi
dealer.
- The airbag system can deploy on ly once.
After an ai rbag has been deployed, it
m ust be replaced with new replacement
parts des igned and app roved espec ially
for your Aud i model version. Replace­
ment of complete airbag systems or air­
bag components must be performed by
qua lified workshops only . Make sure that
any airbag servi ce action is ente red in

198 Driving and en vironm ent
_& WARNING
The temperature o f the exhaust system is
high, both when driving and after stopping
the engine .
- Never touch the exha ust tail p ipes once
they have become hot. This could result in burns .
- Do not park or operate the veh icle in
areas where the hot exhaust system may
come in contact with dry grass, brush,
fuel spill or other material which can cause a fire .
- Do not apply additional undercoating or
rustproofing on or near the exhaust
man ifold , exhaust p ipes, catalytic con ­
verte r or heat shie lds. D uri ng d riving, the
substance used for undercoating cou ld
over heat and cause a fire .
(I) Note
- Be aware that just one tank filling with
l eaded fuel will already seriously de­
grade the perfo rmance of the cata lytic
conve rter.
- Do not exceed the correct engine oil leve l
¢page 215.
- Do not d rive until the fuel tank becomes
completely empty. The eng ine could mis­
fire. Unburned f uel could a lso ge t in to
t h e exhaus t sys tem and this could cause
the ca talyt ic converte r to ove rheat.
- Do no t switch off the ign ition wh ile the
vehicle is moving.
- Do no t continue to operate yo ur vehicle
u nder these condi tions, as otherw ise fuel
can reac h the catalytic converter . This
could result in overheating of the co n­
verter, req uiring its replacement.
- To assure efficient operation of the Emis ­
sion Control System :
- Have your veh icle maintained properly
and in accordance with the service rec­
ommendations in your Wa rranty
&
Ma intenance booklet.
- Lack of proper maintenance as well as
improper use of the vehicle will impa ir the function of the em
ission cont ro l
system and could lead to damage .
~ For the sake of the env ironment
Even when the Emiss ion Con trol Sys tem is
operat ing proper ly, the exha ust gas can
have a sulfur-li ke ex haust gas smell under
some ope rat ing states . This depends on
the sulfur content of the fuel being used .
Using a different brand of fue l may help,
or fil ling the tank with lead -free super
grade gasoline .
Shutting down vehicle
If you would like you r vehicle to remain inop­
erative for a longer per iod of t ime, contact an
Audi o r other spec ia lized dealer. They can ad­
v ise you on ne cessa ry precautions e .g. co rro­
s io n preven tion , maintena nce and s to rage.
Pay a ttent ion to addi tional in fo rmat ion con­
cerning the battery. Refer to

Operate your vehicle
economically and
minimize pollution
General
Your p ersonal style of driving will determine
the economy of your vehicle , as well as ex ­
haust and nois e le ve ls .
Fu el economy, environmenta l impact, and
wear on your engine , brakes and tires largely
depend on three factors:
- your personal d riving style
- operati ng conditions
- technical limitat ions
If you an tic ipate what you need to do next and
drive economically, you can easily cut your
fuel consumpt io n by 10 -15 percent . This sec ­
t ion w ill give you some tips on how you can
help the e nvir onment and your pocketbook .

224 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 exp losive.
- 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 d uring charg­
ing should be washed off w it h a solution
of warm water and ba kin g 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 ele ct ronic components, such
as co ntrol units, relays, rad io, etc. , a s 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.

~ page 193. The inte lligen t energy m anage­
ment system w ill keep the engine batte ry
charged better than vehicles w it h out t his sys­
tem . T o make sure the additional e lectrical en ­
ergy is available once again after you have
changed t he battery, we recommend that you
install batteries of the same type and manu ­
facture only (the same as those ins talled at
the t ime your vehicle was delivered). Specifi­
cations a re listed o n the battery hous ing. You r
author ized de aler m ust code the b attery in
the ene rgy management system to enable yo u
to use the energy managemen t fu nctions co r­
rectly after replac ing 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 .
@ For the sake of the environment
B ecause o f the p rob lem of p roper disposal
