158 Airb ag sys te m
- Have the airbag system inspected by
your Audi dealer before transporting
anyone on the front passenger seat.
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
P ASS ENGER AIR BA G OFF light w ill stay
on .
Repair, care and disposal of the airbags
Parts of the a irbag system 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 of 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 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 deploy ing when needed or deploying
an airbag unexpectedly:
- Never cover, obstruct, or change the
steering wheel ho rn pad or airbag cover
or the instrument pane l or modify them
in any way .
- Never attach any objects such as cup
holders or telephone mountings to the
surfaces covering the airbag uni ts.
- For cleaning the horn pad or instrument
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 a irbag system.
- All work on the steering wheel, instru­
ment panel, front seats or e lectr ica l sys­
tem (including the installation of audio
equ ipment, cellu lar telephones and CB
radios, etc.) must be performed by a
qualified technic ian who has the training
and specia l equipment necessary.
- For any wo rk on the airbag system, we
strongly recommend that yo u see your
author ized Audi dealer or qualified work­
shop.
- Never modify the front bumper or parts
of the vehicle body.
- Always make sure that the s ide airbag
can inf late without inte rfe rence:
- Never install seat covers or rep lace­
ment upholstery 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
inflate.
- Damage to the orig inal seat covers or
to the seam in the area of the side a ir­
bag module must a lways be repaired
immediately by an author ized Audi
dealer .
- The airbag system can deploy on ly once .
After an a irbag has been deployed, it
must be replaced w ith new replacement
pa rts des igned and app roved es pecially
for your Aud i mo del ve rsion. Replace ­
ment of comple te airbag systems or air ­
bag components must be performed by
qualified wor kshops only . Make sure that
any airbag service action is entered in
your Audi Warranty

200 Driving and en vir onm 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 pipes 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 ­
verter 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 218.
- 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 reach 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 operat ing states . This depends on
the sulfur content of the fuel being used .
Using a different brand of fue l may help,
or filling 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 ¢
page 223 .
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 ip ate 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 .

CD Note
Never use a fast charger as a booster to
start the engine. This will seriously dam­
age sensitive electronic components, such
as control units, relays, 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 .
Intelligent energy management in your vehi­
cle is respons ible for distributing the electri­
cal energy throughout your vehicle
c::> page 195. The intelligent energy manage­
ment system w ill keep the engine battery
charged bette r than vehicles w ithout t his sys­
tem. To make sure the additional electr ica l 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 time your vehicle was delivered). Specifi­
cations are listed on the battery hous ing. Your
author ized dealer must code the battery in
the energy management system to enable you
to use the energy management functions cor­
rectly after replac ing the battery.
The new battery must have the same capacity,
voltage (12-volts), amperage, const ruct ion
and p lug sealing.
When installing the battery, make sure the ig­
n ition and all electr ical consumers are sw itch­
ed off .
CD Note
Make sure the ventilation hose on the s ide
of the battery is connected, otherwise
fumes or battery ac id can leak out.
@ For the sake of the environment
Because of the problem of proper d isposal
of a battery, we recommend your author­
ized Aud i dealer change the battery for
you . Batteries contain su lfuric ac id and
Checkin g and fillin g 22 7
lead and must always be disposed o f prop­
erly in compliance with a ll environmental
regulations. Disposing of vehicle batter ies
i mproperly is very dangerous to the envi­
ronment .
