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 cup holders
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
Airbag system
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 compo­nents 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.

q &.. However, we recommend not using a
thawed battery again because the battery casing
can be cracked due to ice formation and can leak
battery acid.
Batt ery chargi ng (Maximum cha rging rate of
30 amp s/14 .8 Volt )
When charging at
low voltages (e.g. with a trickl e
cha rger ), the battery cables do not have to be
d isconnected first. The battery caps shou ld
not
be opened when charg ing a battery.
It is not necessary to remove the battery from
the luggage compartment.
Fast charging th e battery (char ging rat e
above 14 .8 Vo lt s)
For technical reasons do not use a battery charg ­
er that uses voltage greater 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.
- 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 hous ing 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. Hyd rogen gas generat­
ed by t he battery is explos ive.
- To reduce the danger of explosion, never
co nnect or disconnect cha rger cables while
the cha rger is operating.
- Fast charg ing a battery is dangerous and
should only be attempted by a competent
tec hnician with the p roper equipment.
- Battery acid that may spill du ring charg ing
sho uld be washed off w ith a so lution of
wa rm w ater and baking soda to ne utralize
the acid .
Checking and Fillin g
(D Note
Never use a fast charger as a booster to start
the engine . This will ser iously damage sensi­
tive electronic components, s uch as control
units, relays, radio, etc., as well as the battery
charger.
Battery replacement
The new battery must hove the some specifica­
tions and dimensions as the original equipment
battery.
Intelligent energy management in your vehicle is
responsible for distributing the electrical energy
t h roughout your vehicle
q page 175. The intelli­
gent energy management system w ill keep the
engine battery charged better then vehicles with­
out this system. To make s ure the addit ional elec­
t rical energy is ava ilab le once again afte r yo u
have changed the battery, we recommend that
you install batteries of the same type and man u­
facture on ly (the same as those insta lled at the
t ime yo ur vehicle was delivered). Specifications
are listed on the battery hous ing. Your author­
ized Audi dealer must code the battery in the en­
ergy management system to enab le you to use
the e nergy management fu nctions correctly after
replacing the battery.
If it is not possib le to use a battery of this type,
the new battery must have the same capac ity,
voltage ( 12-volts), amperage, construction and
plug sealing.
When installing the battery, make sure the igni­
t ion and all electr ica l consumers are turned off.
(D Note
Make sure the ventilat ion hose on the side of
the battery is connected, otherwise fumes or
battery acid can leak out.
@ For the sake of the environment
Because of the prob lem of proper disposal of
a battery, we recommend your authorized
Audi dealer change the battery for you. Bat­
teries contain sulfur ic acid and lead and must
a lways be d isposed of properly in compliance ..,.
