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.

The all-wheel drive concept is designed for high
engine power . Your vehicle is exceptionally pow­
erful and has excellent driving character istics
both under normal driving conditions and on
snow and ice. Always read and follow safety pre­
cautions <=>
,&.
Winter tire s
When driving in the winter, your vehicle with all­
wheel drive has an advantage, even with regular
tires. In winter road conditions it may be advisa­
ble to mount w inter tires (or all-season tires) for
improved driveability and braking: these tires
must be mounted on
all four wheels. See also
<=> page 224, Winter tires.
Tire chains
Where tire chains are mandatory on certain
roads, this normally also applies to vehicles with
all-wheel drive <=>
page 224, Snow chains.
Replacing wheels/tires
Vehicles with all-wheel drive must a lways have
tires of the same size. Also avoid tires with differ­
ent tread depths. For details see page
<=>
page 216, New tires or wheels.
Off-Road driving?
Your Audi does not have enough ground clear­
ance to be used as an off-road vehicle. It is there­
fore best to avoid rough tracks and uneven ter­
rain as much as possible. Also refer to
<=>page 177.
A WARNING
Always adjust your driving to road and traffic
conditions. Do not let the extra safety afford­
ed by all-wheel drive tempt you into taking
extra risks.
- Although the all-wheel dr ive is very effec­
t ive, always remember that braking capacity
is limited by tire traction. You should there­
fore not drive at excessive speeds on icy or
slippery road surfaces.
- On wet road surfaces, be careful not to dr ive
too fast because the front wheels could be ­
gin to slide on top of the water (aquap lan­
ing). If this shou ld occur, you will have no

warning from a sudden increase in engine
speed as with a front-wheel drive vehicle.
Always drive at speeds which are suited to the road conditions -risk of crash.
Energy management
Starting ability is optimized
Energy management controls the distribution of
electrical energy and thus optimizes the availa­
bility of electrical energy for starting the engine.
If a vehicle with a conventional energy system is
not driven for a long pe riod of time, the battery
is discharged by idling current consumers (e.g.
i mmobil izer). In certain circumstances it can re­
su lt in there being insufficient energy available to
start the engine.
Intelligent energy management in your vehicle
hand les the distribution of electrical energy.
Starting ability is markedly improved and the life
of the battery is extended.
Basically, energy management consists of
bat­
tery diagnosis , idling current management
and
dynamic energy management.
Battery diagnosis
Battery diagnosis continuously determines the
state of the battery . Sensors determine battery
vo lta ge, battery current and battery tempera­
tu re. This determines the current state of charge
and the power of the battery.
Idling current management
Idling current management reduces energy con­
sumption whi le the vehicle is standing. With the
ignition switched off, it contro ls the energy sup­
ply to the various electrical components. Data
from battery diagnosis is considered.
Depending on the battery's state of charge, indi­
vidual consumers are gradually turned off to pre­
vent excessive discharge of the battery and thus
maintain starting capability .
Dynamic energy management
While the vehicle is being driven, dynamic energy
management distr ibutes the energy generated ..,.
175

Smart Technology
according to the needs of the individual compo­
nents. It regulates consumption, so that more
electrical energy is not being used than is being
generated and ensures an opt imal state of
charge for the battery.
(D Tips
- But even energy management cannot neg­
ate the limits of physics. Consider that the
power and life of a battery are limited.
- If starting ability is threatened, the indica­ tor light (•) appears ¢
page 16.
What you should know
The highest priority is given to maintaining start­
ing capability.
The battery is severely taxed in short-distance
driving, in city traffic and during the cold time of
year. Abundant electrica l energy is requ ired, but
only a little is generated. It is also critical if the
engine is not running and electrical components
are turned on. In th is instance energy is being
consumed but none is being generated.
It is in precisely these situations that you will no­
tice energy management actively regulating the
d istr ibut ion of energy.
Vehicle stands for an extended period
If you do not drive your vehicle over a period of
several days or weeks, e lectrical components are
gradually cut back or switched
off. This reduces
energy consumption and maintains starting ca­ pability over a longer period . Some of the con­
ven ience funct ions may not operate, such as the
interior lights or the powe r seat adjustment. The
conven ience functions w ill be available again
when yo u sw itch on the ignition and start the en­
gine.
With the engine turned off
I f you listen to the radio, for example, with the
engine turned
off or use other MMI functions,
the battery is being discha rged .
If starting capability is jeopardized due to energy
consumption, a message appears in the MMI dis­
p la y. The message indicates that the system will
176
be switched off automatically in a moment . If
you wish to continue using the functions, you have to start the eng ine.
With the engine running
Althoug h elec trical energy is generated when the
vehicle is being driven, the battery can become
discharged . This happens mostly when litt le en ­
ergy is being generated and a great dea l con­
sumed and the battery's state of charge is not
optimal.
To bring the energy ba lance back into equilibri­
u m, consumers which require especially large
amounts of energy are temporar ily cut back or
switched
off. Heating systems in part icular re­
quire a great deal of energy. If you notice, for ex­
ample, that the heated seats* or the heated rear
window a re not heating, they have been tempo­
rarily cut back or switched
off. These systems w ill
be ava ilable again as soon as the energy ba lance
has been restored.
You will also notice that engine idle speed has
been increased slightly . Thi s is normal and not a
cause for concern. By incr easing eng ine idle
speed the additional energy required is generated
and the battery is cha rged.
