-Have the airbag system inspected by
your Audi dealer before transporting
anyone on the front passenger seat.
(D Tips
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

Repair, care and disposal of the airbags
Parts of the airbag system are installed at
many different places 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 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 dis
carded components do not cause injury or pol
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 deploying when needed or deploying
an airbag unexpectedly:
- Never cover, obstruct, or change the
steering wheel horn pad or airbag cover
or the instrument panel or modify them
in any way .
- Never attach any objects such as cup
holders or telephone mountings to the
surfaces covering the airbag units.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one
moistened 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 de
ploy and protect properly.
Airbag system 165
- Never repair, adjust, or change any parts
of the airbag system.
- All work on the steering wheel, instru
ment panel, front seats or electrical sys
tem (including the installation of audio
equipment, cellular telephones and CB radios, etc .) must be performed by a
qualified technician who has the training
and special equipment necessary.
- For any work on the airbag system, we
strongly recommend that you see your
authorized Audi dealer or qualified work
shop.
- 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 upholstery over the front seat
backs that have not been specifically
approved by Audi.
- Never use additional seat cushions that
cover the areas where the side airbags
inflate.
- Damage to the original seat covers or
to the seam in the area of the side air
bag module must always be repaired
immediately by an authorized Audi
dealer.
- The airbag system can deploy 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. Replace ment of complete airbag systems or air
bag components must be performed by
qualified workshops only. Make sure that
any airbag service action is entered in
your Audi Warranty
& Maintenance book
let under

@ Tips
- But even energy management cannot
negate the limits o f physics. Consider
that the power and life of a battery are
limited.
- If starting ab ility is threatened, the indi
cator light (•) appears ¢
page 17.
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severely taxed in short-dis tance
driving, in city traffic and d uring the co ld time
of year . Abu ndant e lectrica l energy is re
q uired, but only a litt le is generated . It is also
cr itical if the engine is not runn ing and electri
cal components are turned on. In th is in
stance energy is being consumed but none is
be ing generated.
It is in precisely these situations that you w ill
notice energy management actively regulat
i n g the distribution of energy.
Vehicle stand s for an e xte nded period
If yo u do not drive you r vehicle over a period
of severa l days or weeks, electrical compo
nents are grad ually cut back or switched off.
This reduces energy consumption and main tains starting capab ility over a longer per iod.
Some of the conven ience functions may not
operate, such as the inter ior lights o r the
power seat adjustment. The conven ience
f u nctions will be ava ilable again whe n you
switch on the igni tion and start the engine.
With the engine turned off
If you lis ten to t he radio, for example, with
the eng ine turned off or use othe r MM I fu nc
tions, the bat te ry is being discha rged .
If starting capability is jeopardized due to en
e rgy consumpt ion, the follow ing warning ap
pears in the MMI disp lay :
Int ellig ent technolog y 203
Plea se start the engine soon or the sy stem
will be turned off .
The wa rni ng ind ic ates th at the sys tem w ill be
t u rned o ff autom atically a fter 3 minu tes. If
you w ish to continue using the funct ions, yo u
have to start the engine.
With the engine running
Althoug h elec trical energy is generated when
t h e ve hicl e is being driven, t he battery can be
come d isc harged. This happe ns mostly when
little energy is being generated and a g reat
deal consumed and the battery's state of
charge is not opt imal.
T o b ring the energy ba lance back in to equili
brium, consumers which req uir e especially
l a rge amounts of energy a re temporari ly cut
back or sw itched off. Heat ing systems in par
ticular require a great deal of energy. If you notice, for example, that the heated seats* or
the heated rear window are not heating, they
have been temporarily cut back or switched
off . These systems w ill be availabl e again as
soon as the ene rgy balance has been restored.
You w ill also notice that engine id le speed has
been increased slightly . Thi s is no rmal and not
a cause for concern. By inc reas ing engi ne id le
speed the additional e nergy requi red is gene r
ated and the b attery is charged.

cracked and weakened when the battery
froze.
- Charge the battery in a well ventilated
area. Keep away from open flame or elec
trical spark. Do not smoke. Hydrogen gas
generated by the battery is explosive.
- To reduce the danger of explosion, never
connect or disconnect charger cables
while the charger is operating.
- Fast charging a battery is dangerous and
should only be attempted by a compe
tent technician with the proper equip
ment .
- Battery acid that may spill during charg
ing should be washed off with a solution
of warm water and baking soda to neu
tralize the acid.
0 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 responsible for distributing the electri
cal energy throughout your vehicle
q page 202. The intelligent energy manage
ment system will keep the engine battery
charged better than vehicles without this sys
tem. To make sure the additional electrical 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 housing. Your
authorized dealer must code the battery in
the energy management system to enable you
to use the energy management functions cor rectly after replacing the battery.
Checking and filling 241
The new battery must have the same capacity,
voltage (12-volts), amperage, construction and plug sealing.
When installing the battery, make sure the ig
nition and all electrical consumers are switch
ed off.
(D Note
Make sure the ventilation hose on the side
of the battery is connected, otherwise
fumes or battery acid can leak out.
- Vehicles with the Start-Stop-System* are
equipped with a special cycle-proof AGM
battery. Installing a different type of
battery can cause problems in the vehi
cle electrical system. When replacing the
vehicle battery, always install one with
the same specifications as the original
battery.
@ For the sake of the environment
Because of the problem of proper disposal
of a battery, we recommend your author
ized Audi dealer change the battery for
you. Batteries contain sulfuric acid and lead and must always be disposed of prop
erly in compliance with all environmental
regulations. Disposing of vehicle batteries
improperly is very dangerous to the envi
ronment.
