Airbag system
(D Tips
If the weight-sensing mat in the front passen­
ger seat detects an empty seat, the front air­
bag on the passenger side will be turned off,
and
PASSENGER AIR BAG OFF will stay on.
Repair , care and disposal of the airbags
Parts of the airbag system are installed at many
different places on your Audi. Installing , remov­
ing, 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 discarded
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 airbag 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. Solvents or cleaners could damage the airbag cover or change
the stiffness or strength of the material so
that the airbag cannot deploy and protect properly.
- Never repair, adjust , or change any parts of
the airbag system.
- All work on the steering wheel, instrument
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 you 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 without interference:
- Never install seat covers or replacement
upholstery over the front seatbacks that
have not been specifically approved by
Audi .
- Never use additional seat cushions that
cover the areas where the side airbags in­
flate.
- Damage to the original seat covers or to
the seam in the area of the side airbag
module must always be repaired immedi­
ately by an authorized Audi dealer .
- The airbag system can be activated only
once . After an airbag has inflated, it must
be replaced by an authorized Audi dealer or
qualified technician who has the technical
information, training and special equipment
necessary.
- The airbag system can be deployed 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. Replacement of complete airbag systems or airbag compo­
nents must be performed by qualified work­
shops only. Make sure that any airbag serv­
ice action is entered in your 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 pyrotechnic
circuit interrupter.
- Work on the pyrotechnic circuit interrupt­
er must only be performed by a qualified
dealer - risk of an accident!
- If the vehicle or the circuit interrupter is
scrapped, all applicable safety precautions
must be followed.

~ Open the cover on the positive pole ~ fig. 165.
~ Connect the charger connectors accord ing to
the instructions to the
jump start bolts. (Bolts
under the cover= "positive", Bo lts with hex
head = "negative") .
~ Only now plug the mains lead for the charging
equipment into the wall outlet and turn it on
~ & -
~ Make sure the charging rate is not over
30 amps/14.8 Volt.
~ When the battery is fully charged: Turn the
charging equipment off and remove the mains
lead from the wall outlet.
~ Now remove the clamps for the charging equip-
ment.
~ Close the cover on the posit ive pole .
~ Close the hood ~ page 191.
A discharged battery can freeze at temperatures
of only 32 °F (0 °C) . Allow a frozen battery to
thaw completely before attempt ing to charge it
~ & . However, we recommend not using a
thawed batte ry again because the battery casing
can be cracked due to ice formation and can leak
battery acid.
Battery charging (Maximum charging rate of
30 amps/14.8 Volt)
When charging at low voltages (e .g . with a trick­
le charger),
the battery cables do not have to be
disconnected first. The battery caps should
not
be opened when charging a battery.
It is not necessary to remove the battery from
the luggage compartme nt.
Fast charging the battery (charging rate
above 14.8 Volts)
Fo r techn ical reasons do not use a battery charg­
e r that uses voltage greate r than 14.8 Volts to
charge your vehicle 's battery.
A WARNING
Charging a battery can be dangerous.
- Always follow the operating instructions
provided by the battery charger manufactur­
er when charging your battery .
Checking and Filling
-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 which were frozen.
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 electrical
spark. Do not smoke . Hydrogen gas generat­
ed by the battery is explosive.
- To reduce the danger of explosion, never
connect or disconnect charger cables while
the charger is operating .
- Fast charg ing a battery is dangerous and
should only be attempted by a competent
technician with the proper equipment.
- Battery acid that may spill during charging should be washed off w ith a solution of
warm water and baking soda to neutralize
the acid .
@ Note
Never use a fast charger as a booster to start
the engine . This will seriously damage sensi­
tive electronic components, such as control
units, relays, radio, etc., as well as the battery
cha rge r.
Battery replacement
The new battery must have the same specifica­
tions and dimensions as the original equipment
battery.
Intelligent energy management in your vehicle is
r esponsib le for distr ibut ing the electrical energy
throughout your vehicle ~
page 175. The intelli­
gent energy management system will keep the
engine battery charged better then vehicles with ­
out this system. To make sure the additional
electrical energy 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) . Specifications
are listed on the battery housing . Your author­
ized Audi dealer must code the battery in the en-
ergy managemen t system to enable you to use
