Otherw ise the steering lock wi ll engage
and you will not be able to steer the vehi­
cle.
- Please note that the brake booster and
power steering only work when the en-
Dri vin g 77
gine is running. When the engine off, you
must use more force to steer or brake
the vehicle. Because the usual steering
and brak ing capability is not avai lab le,
the risk of accidents or injur ies increases.
- Always take the vehicle key with you
when leaving the vehicle, even for a
short period of time. This applies part ic­
ularly when children remain in the veh i­
cle. Otherwise the ch ild ren could start
the engine or operate electrical equip­
men t such as power w indows.
(D Note
- Avo id h igh engine speed, full throttle,
and heavy eng ine load as long as the en­
gine has no t reached operat ing tempera­
t u re yet . You could damage the engine.
- T he engine cannot be started by pushi ng
or towing.

off using the

move the selector lever into the P position
and open the driver's door.
The locked steering helps prevent vehicle
theft.
Emergency off function
If it is absolutely necessary, the engine can al­
so be turned off while driving at speeds lower
than 6 mph (10 km/h).
If you press the

appears. To
switch the engine off, press the
I STAR T ENGINE STO PI* button twice in a row
briefly or press and hold for longer than two
seconds.
A WARNING
- Never turn off the engine before the ve­
hicle has come to a complete stop. The
full function of the brake booster and the power steering is not guaranteed. You
must use more force to turn or brake, if
necessary. Because you cannot steer and
brake as you usually would, this could
lead to accidents and serious injuries .
- Please note that the brake booster and
power steering only work when the en­
gine is running. When the engine off, you
must use more force to steer or brake
the vehicle. Because the usual steering and braking capability is not available,
the risk of accidents or injuries increases.
- Always take the vehicle key with you when leaving the vehicle, even for a
short period of time. This applies partic­ ularly when children remain in the vehi­
cle. Otherwise the children could start
the engine or operate electrical equip­
ment such as power windows.
- For safety reasons, always park the vehi­
cle with the selector lever in the P posi-

tion. Otherwise, there is the risk that the
vehicle could roll.
- After the engine has been switched off,
the radiator fan can continue to run for
up to 10 minutes - even with the ignition
switched off. It can also switch on again
after some time if the coolant tempera­
ture rises as a result of heat buildup or if
the engine compartment is heated by sunlight and the engine is hot.
(D Note
If the engine has been under heavy load
for an extended period of time, heat builds
up in the engine compartment after the
engine is switched off - there is a risk of
damaging the engine. For this reason, let
the engine run for at idle for approximate­
ly two minutes before shutting it off.
Starting the engine if there is a

Applies to vehicles: with convenience key
It may not be possible to start the engine un­

162 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 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
AIRBAG REPLACEMENT RE­
CORD.
- 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 technicians who have the ex­ perience, information and special tools
necessary to perform the work safely.
- If the vehicle or the circuit interrupter
is scrapped, all applicable safety pre­
cautions must be followed.
@) For the sake of the environment
Undeployed airbag modules and preten­
sioners might be classified as Perchlorate
Material -special handling may apply, see
