:E ' -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
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 applicable safety precautions
must be followed .
@ For the sake of the environment
Undeployed airbag modules and pretension­
ers might be classified as Perchlorate 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 with pretensioners are scrapped,
all applicable laws and regulations must be
observed. Your authorized Audi dealer is fa­
miliar with these requirements and we recom­
mend that you have your dealer perform this
service 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 tire-rim
combinations not approved by Audi, lowering the
veh icle, chang ing the stiffness of the suspens ion,
including 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 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 measured by
the sensors and prevent the airbag from deploy­
ing when it should .
Airbag system
A WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced Airbag performance and in­
crease the risk of serious personal injury in a
crash.
- Never install suspension components that
do not have the same performance charac­
teristics as the components originally instal­
led on your vehicle.
- Never use tire-rim combinations that have
not been approved by Audi.
Side airbags
· Description of side airbags
The airbag system can provide supplemental
protection to properly restrained occupants.
Fig. 237 Side a irbag locatio n in the driver's seat
The side airbags are located in the sides of the
front seat backrests ¢
fig. 23 7 and the rear back­
rest* facing the doors.
The side airbags installed for the front seating
pos itions have been des igned and certified to
help reduce the risk of injury that can be caused
by airbags when they inflate, particularly when
the occupant s itting next to it is not seated prop­
erly. The side airbag for the front passenger seat
can be used w ith proper ly installed chi ld re­
straints . Please be sure to read the important in­
formation and warnings whenever using a child
restraint in a vehicle: Safety belts¢

Working in the engine compartment
Special care is required if you are working in the engine compartment
F or wo rk in th e en gine co mpartm en t, suc h as

s af ety pr ecau tions pr ovided in the f ollowin g in­
f o rm ation . The engine comp artm en t is a d an­
g ero us ar ea .
¢ ,&. .
A WARNING
- T urn the engine off.
- Swit ch the ign ition off.
- Set the parking brake .
- Select the "P" selector lever posit ion .
- Let the engine cool down.
- Never open the hood when there is steam or coolant escaping from the eng ine 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 flu ids on a hot engine. These flu­
ids (such as the anti -freezing agent con­
tained in the coolant) can ignite .
- Avoid short circu its in the electrical system .
- When working in the engine compartment,
remember that the radiator fan can sw itch
on even if the ign ition is switched off, which
increases the risk of injury .
- Never open the cap on the coolant expan­
sion tank when the eng ine 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 w ith the en­
gine running, there is additional danger due
to moving components (such as the ribbed
Ch eck ing and F illing
be lt, 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 veh i­
cle is stat ionary but the eng ine is running
and a gear is engaged . Otherwise, the veh i­
cle will start to move immed iately and this
could result in an acc ident.
- Pay attent ion to the following warnings
when work on the fue l system is required :
- Do not smoke .
- Never wor k nea r open flames .
- Always have a working fi re extingu isher
nearby.
- All work on the battery or electrical system
in your veh icle can result in inju ries, chemi­
cal burns, acc iden ts or bu rns . Because of
this, all work m ust be performed
onl y by an
authorized Audi dealer or authorized Audi
Service Facility.
- To reduce the risk o f electric shock and in ­
jury, never touch the following components
when the engine is running or is being start­
ed:
- Ign it ion cable
- Other components in the electronic high -
voltage ign ition system
- If you must check or perform work on the
engine wh ile it is running:
- Set the parking brake first and then se lect
the "P" selector lever position .
- Always proceed w ith 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 .
- lim it your exposure to exhaust and chemi­
cals to as short a time as possible
