Master key with remote control
The remote control allows you to lock or un­
lock the vehicle electronically .
The transmitter and battery are located in the
head of the remote control. The receiver is lo­
cated inside the vehicle. The maximum effec ­
tive range depends on several things . Remem­
ber, if the battery is wea k, the effective range
decreases.
If you need to replace the remote control, or if
you need to have it repaired, you must see
your author ized Audi dealer. Only then can
you use the key again.

122 Airbag system
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.
- 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 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 replace­
ment parts designed and approved espe­
cially for your Audi model version. Re­
placement of complete airbag systems
or airbag components must be per­
formed by qualified workshops only.
Make sure that any airbag service action
is entered in your Audi Warranty & Main­
tenance booklet under
AIRBAG REPLACE­
MENT RECORD.
- For safety reasons in severe accidents,
the alternator and starter are separated
from the vehicle battery with a pyrotech­ nic circuit interrupter.
- Work on the pyrotechnic circuit inter­
rupter must only be performed by a
qualified dealer -risk of an accident!
- If the vehicle or the circuit interrupter
is scrapped, all applicable safety pre­
cautions must be followed.

than is being generated and ensures an opti­mal state of charge for the battery.
@ Tips
- But even energy management cannot
negate the limits o f physics. Consider
that the power and life of a battery are
li mited.
- If starting ab ility is threatened, you are
i nformed by a warning
¢ page 157,
Driver notification in the instrument
cluster display.
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severely taxed in short-distance
driving, in city traffic and during the co ld time
of year. Abundant e lectrica l energy is re­
quired, but only a litt le is generated. It is also
cr itical if the engine is not run ning and electri­
cal components are turned on. In th is in­
stance energy is being consumed but non e is
be ing gene rated.
It is in precisely these situations that you w ill
notice energy management actively regulat ­
in g the distribution of energy .
Vehicle stands for an extended period
If you do not drive your vehicle over a period
of several days or weeks, electrical compo­
nents are gradually cut back or switched off.
This reduces energy consumption and mai n­
tains sta rting capab ility over a longer per iod.
Take into consideration that when you un lock
your ve hicle, some co nvenience functions,
such as the remote key or power seat adjust ­
ment, may not be available . The convenience
f u nctions w ill be ava ilable again whe n you
turn on the igni tion and star t the eng ine.
With the engine turned off
If you listen to the radio, for example, with
the eng ine turned off, the battery is being dis­
charged .
Intellig ent technolog y 157
If starting capability is jeo pardi zed d ue to en ­
ergy consumption, a message appears in the
drive r information d isplay .
You have to start t he engine to charge the
batte ry .
With the engine running
Although e lectrical energy is generated when
the ve hicl e is being driven, t he battery can be­
c ome disc harged. This happe ns mostly when
li ttle energy is being generated and a g reat
deal consumed and t he battery's sta te of
c h arge is not optimal.
T o b ring the energy b alance b ack into equili ­
br ium, consumers which requ ire espe cially
la rge amounts of energy a re temporari ly cut
back or switched off . Heating systems in pa r­
ticu lar require a great deal of energy. If yo u
notice, for example, that the heated seats* or
the heated rear window are not heating, they
have been temporarily cut back or sw itched
off . These systems w ill be available 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 . T hi s is normal and not
a cause for conce rn . By i ncreas ing eng ine id le
speed the additional energy r equired is gene r­
ated and the battery is charged.
Driver notification in the instrument
cluster display
If battery power drops into the range where it
can limit the ability of the engine to start, this
is shown in the instrument cluster display
with the following driver message:
(•) Low battery charge: battery will be
charged while driving
T his no tificat ion reminds yo u that the star ting
capability of the engine may be lim ited . As
soon as you sta rt dr iving again, the battery
will be recharged and the not ificat ion w ill go
out. •
