- For safety reasons in severe accidents, the
alternator and starter are separated from
the vehicle battery with a pyrotechn ic circuit
in terrupter.

er must only be performed by a qualified
technicians who have the experience, in­
formation and special tools necessary to
perform the work safely.
- If the vehicle 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 veh icle o r parts of the re­
stra int system including airbag modules and
safety belts w it h pretensioners are scrapped,
all applicable laws and regu lations must be

Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced A irbag System
pe rforms in a crash. For e xamp le, using t ire -r im
comb inations no t approved by Audi, lowering t he
veh icle, chang ing the stiffness o f the suspe nsio n,
i n cluding the springs, suspension struts, shock
absorbers etc . can change the forces that are
measured by the airbag sensors and sent to the
electronic contro l unit . Some suspens ion changes
can, for example, increase the force levels meas­
ured by the sensors and make the airbag system
deploy in c rashes in w hich it would not deploy if
the changes had not been made. Other ki nds of
200
changes may reduce the force levels measured by
the sensors and prevent the airbag from deploy­
i ng when it should .
_& 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 install suspension components that do not have the same performance charac­
ter istics as the components origina lly instal­
led on your vehicle.
- Never use tire-r im combinations that have
not been approved by Aud i.

to moving components (such as the ribbed belt, alternator and radiator fan) and from
the high-voltage ignition system.
- Never reach into the radiator fan. The elec­
tric auxiliary fan is controlled by tempera­
ture and can switch on suddenly.
- Pay attention to the following warnings list­ ed when work on the fuel system or on the
electrical equipment is required.
- Always d isconnect the vehicle battery
from the vehicle electrical system
- Do not smoke
- Never work near open flames
- Always have a working fire extinguisher nearby
- To reduce the risk of electric shock and in­
jury, never touch the following components when the eng ine is running or is being start­
ed:
- Ignition cable
- Other components in the electronic h igh -
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 ha ir do not
become caught in the radiator fan, fan
be lt 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 cloth ing that can
hang down into the engine.
- L imit your exposure to exhaust and chemi­
cals to as short a time as possible~&.
