and
PASS ENGE R AIR BAG OFF will stay on.
Repair, care and disposal of the airbags
Parts of the a irbag system are installed at many
d ifferent places on your Audi . Install ing , remov­
ing, servicing or repa iring a part in an area of the
veh icle can damage a part of a n airbag system
and p revent that system from working properly
in a co llision.
There are some important things you have to know to make sure that the effect iveness of the
sys tem w ill not be impaired and that d iscarded
components do not cause injury or pollute the
environment.
A WARNING
-
Improper care, servicing and repair proce­
dures can increase the risk of personal injury
and death by preventing an airbag from de­
ploying when needed or deploying an airbag
unexpectedly :
- Never cover, obstruct, or change the steer­
ing wheel horn pad or a irbag cover or the in ­
strument panel or modify them in any way .
- Never attach any objects such as cupholders
or telephone mountings to the surfaces cov­
ering the airbag units.
- For cleaning the horn pad or instrument panel, use only a soft, dry cloth or one mois­
tened with plain water. So lvents or cleaners
could damage the a irbag cover or change
the stiffness o r strength of the mater ial so
that the airbag cannot dep loy and protect
properly .
- Never repa ir, adjust, or change any parts of
the airbag system.
- All work on the steering wheel, inst rument
panel, front seats or electrical system (in­
cluding the installation of audio equipment,
cellular telephones and CB radios, etc.)
must be performed by a qualified technician
142 who has the training and special equipment
necessary.
- For any work on the airbag system, we
strongly recommend that yo u see your au­
thorized Audi dealer or qualified workshop.
- Never modify the front bumper or parts of
the vehicle body.
- Always make sure that the side airbag can
inflate w ithout interference :
- Never install seat covers or rep lacement
upholstery over the front seatbacks that
have not been specifically approved by
A udi .
- Never use additional seat cushions that
cover the areas where the side a irbags in­
flate.
- Damage to the orig inal seat cove rs or to
the seam in the are a of the side ai rbag
module must a lways be repaired immedi­
ate ly by an authorized Aud i dealer.
- The a irb ag sys tem can be activated only
once . After an airbag has inflated, it mus t
be rep laced by an authorized Audi dealer or
qualif ied technic ian who has the technical
information, training and specia l equipment
necessary.
- The a irbag system can be deployed only
once . After an airbag has been deployed, it
must be replaced with new replacement parts des igned and approved espec ially for
your Aud i model version. Replacement of
comp lete airbag systems or airbag compo­
nents must be perfo rmed by qualified work­
shops only. Ma ke s ure tha t any airbag serv­
ice action is entered in yo ur Audi Warranty
&
Maintenance booklet under AIRBAG RE­
PLACEMENT RECORD.
- In accidents when an airbag is deployed, the
vehicle battery separates the alternator and
the starter from the vehicle electrical sys­
tem for safety reasons with a pyrotechn ic
circuit interrupter .
- Work on the pyrotechnic c ircuit inte rrupt­
er must on ly be performed by a qua lified
dealer -risk of an acc iden t!
- If the vehicle or the circuit interr upter is
scrapped, all app licable safety precautions
must be followed .

A discharged battery can freeze at temperatures
of only 32 °F (0 °C). Allow a frozen battery to
thaw comp letely before attempting to charge it
9 & . However, we recommend not using a
thawed batte ry agai n because the batte ry casing
can be cracked due to ice forma tion a nd ca n leak
battery a cid.
Battery charging (Maximum charging rate of
30 amps /14.8 Volt )
When charging at low voltages (e.g. w ith a trickle
c harger ),
the battery cab les do not have to be
d isconnected first. The batte ry caps sho uld
not
be opened when charging a battery.
It is not necess ary to remove the ba tte ry from
t he luggage compa rtment.
Fast charging the battery (charging rate
above 14.8 Volts)
F or technica l reasons do no t use a ba ttery charg­
e r that uses voltage grea ter than 14.8 Vol ts to
charge your vehicle's battery .
A WARNING
Charging a battery can be dangerous.
- Always fo llow the operating instructions
provide d by the batte ry charge r manufactur ­
er when c harging your battery.
Checking and Fillin g
-Never charge a frozen battery. It may ex­
plode because of gas trapped in the ice . Al­
low a frozen battery to thaw out first.
- Do not reuse batteries wh ich were frozen.
The battery housing may have cracked and
weakened whe n the battery froze.
- Charge the battery in a well ventilated area.
K eep away from open flame or electrical
spark. Do not smoke. Hydrogen gas gene rat­
ed by the ba tte ry is explosiv e.
- To reduce the danger of explosion, never
connect or d iscon nect charger cab les wh ile
the charge r is operating.
- Fast cha rging a batte ry is dange rous and
should only be at tempted by a compe tent
technicia n w it h the proper eq uipment.
- Battery acid that may sp ill dur ing cha rging
