supp ly system .
More force is needed to steer and brake the mov ­
ing vehicle when the engine is stopped . If the ve­
hicle is rolling, try to bring it to a stop off to the
side from moving traffic. See an authorized Audi
dealer or authorized Aud i Serv ice Facility for as­

Airbag syste m
service action is entered in your Audi War­
ranty
& Maintenance book let under AIRBAG
REPLACEMENT RECORD.
- For safety reasons in severe accidents, the
alternator and starter are separated from
the vehicle battery with a pyrotechnic circuit interrupter.
- Work on the pyrotechnic circuit interrupt­
er must only be performed by a qualified
dea ler· risk of an accident!
- If the veh icle or the circuit interrupter is
scrapped, all applicab le safety precautions
must be followed .
@ For the sake of the environment
Undeployed airbag modu les and pretension ­
ers might be classified as Perch lorate Materi­
al -special handling may apply, see
www .dtsc.ca.gov/hazardouswaste/perchlo­
rate. When the vehicle or parts of the re­
straint system including airbag modules and
safety belts w ith pretensioners are scrapped,
all applicable laws and regulations must be
observed. Your authorized Audi dealer is fa­
m iliar with these requirements and we recom­
mend that you have your dealer perform this
serv ice for you .
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag System
performs in a crash. For example, using t ire-r im
comb inat ions not approved by Audi, lower ing the
veh icle, chang ing the st iffness of the suspens ion,
including the springs, suspension struts, shock
absorbers etc. can change the forces that are
measured by the airbag senso rs and sent to the
electronic contro l unit. Some suspension changes
can, for example, increase the force levels meas­
ured by the sensors and make the airbag system
deploy in crashes in which it would not deploy if
the changes had not been made. Other kinds of changes may reduce the force levels meas ured by
the sensors and prevent the airbag from deploy­ ing when it should .

A WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim comb inations can
change Advanced Airbag performance and in­
crease the r isk of serious personal injury in a
crash.
- Never insta ll suspension components that
do not have the same performance charac­
ter istics as the components origina lly ins tal­
led on you r vehicle.
- N ever use tire-r im combinations that have
no t been approved by Aud i.
A WARNING
It ems stored between the safety belt buckle
and the center conso le can cause the sensors
in the buckle to send the wrong information
to the electronic contro l module and prevent
the Advanced A irbag System from working
proper ly.
- Always make sure that nothing can interfere
with the safety belt buckles and that they
are not obstructed.
Knee airbags
Description of knee airbags

tal protection to properly restrained front seat
occupants.

Checking and Filling
-Set the parking brake.
- Select the P selector lever position.
- Let the engine cool down.
- Never open the hood when there is steam or
coolant escaping from the engine compart­
ment, because there is a risk that you could
be burned. Wait until no steam or coolant is
escaping.
- Keep children away from the engine com­
partment.
- Never spill fluids on a hot engine. These flu­
ids (such as the anti-freezing agent con­
tained in the coolant) can ignite.
- Avoid short circuits in the electrical system.
- When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of personal injury.
- Never open the cap on the coolant expan­
sion tank when the engine is warm. The
cooling system is under pressure.
- To protect your face, hands, and arms from
hot steam or coolant, cover the cap with a
large cloth when opening.
- Do not remove the engine cover under any
circumstances. This increases the risk of
burns.
- If tests need to be performed with the en­
gine running, there is additional danger due
to moving components (such as the ribbed
belt, alternator and radiator fan) and from
the high-voltage ignition system .
- Do not under any circumstances activate the
throttle inadvertently (for example, by hand
from the engine compartment) if the vehi­
cle is stationary but the engine is running
and a gear is engaged. Otherwise, the vehi­
cle will start to move immediately and this
could result in an accident.
- Pay attention to the following warnings list­
ed when work on the fuel system or on the
electrical equipment is required.
- Do not smoke .
- Never work near open flames.
- Always have a working fire extinguisher
nearby
- All work on the battery or electrical system
in your vehicle can result in injuries, chemi-
272
cal burns, accidents or burns. Because of
this, all work must be performed
only by an
authorized Audi dealer or authorized Audi
Service Facility .
- To reduce the risk of electric shock and in­
jury, never touch the following components when the engine is running or is being start­
ed:
- Ignition cable
- Other components in the electronic high-
voltage ignition system
- If you must check or perform work on the
engine while it is running:
- Set the parking brake and place the selec­ tor lever in the P (park) position first.
- Always proceed with extreme caution so
that clothing, jewelry or long hair do not
become caught in the radiator fan, fan
belt or other moving components or do
not come into contact with hot compo­
nents . Tie back long hair before beginning
work and do not wear clothing that can
hang down into the engine .
- Limit your exposure to exhaust and chemi­
cals to as short a time as possible
