AIRBAG RE­
PLACEMENT RECORD.
- Applies to plug-in hybrid* vehicles: In the
event of a co llision where the a irbags de­
ploy, the electrical connection to the high­
voltage battery is automatically disconnect­
ed. This prevents a short c ircuit.
@) For the sake of the environment
Undep loyed airbag modules 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 or parts of the re­
straint system incl uding airbag modules and
safety belts with pre tensioners 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 Sys tem
performs in a crash. For examp le, using tire-r im
combinations not approved by Audi, lowering the
vehicle, changing the stiffness of the suspension, including the springs , suspension struts, shock
absorbers etc. can change the forces that are
measured by the airbag sensors and sent to the
electronic control unit . Some suspens ion changes
can, for example, increase the force levels meas­
ured by the sensors and make the airbag system
deploy in crashes in wh ich it would not dep loy if
t he changes had no t 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.
.&_ WARNING
Changing the vehicle 's s uspension incl uding
use of unapproved tire-rim combinations can
change Advanced A irbag performance and in-
Airb ag sys tem
crease the risk of serious personal injury in a
crash.
- Never install suspension components that
do not have the same performance charac­
ter istics as the components originally instal­
led on your vehicle.
- Never use tire-rim combinations that have
not been approved by Audi.
Knee airbags
Description of knee airbags
Applies to: vehicles wit h knee airbags
The knee airbag system con provide supplemen­
tal protection to properly restrained front seat
occupants.
F ig . 24 S Driver 's knee airbag
The driver knee airbag is in the instrument panel
underneath the steering
whee l¢ fig. 245, the
airbag for the passenger is at about the same
height in the instrument pane l underneath the
glove compartment.
The knee airbag offers additiona l protection to
t h e driver's and passenger's knees and upper and
lower thigh areas a nd supplements the p rotec­
t io n prov ided by the safety belts .
If the front airbags deploy, the knee airbags also
deploy in frontal collis ions when the deployment
threshold stored in the control un it is met
¢ page 2 77, More important things to know
about front airbags .
In addition to their normal safety function, safe­
ty belts help keep the dr iver or front passenger in
pos it ion in a frontal collision so t hat the airbags
can p rovide supplemental protection .

-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.
-Never reach into the radiator fan. The elec­
tric auxiliary fan is controlled by tempera­
ture and can switch on suddenly.
-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 •
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 .
Checking and Filling
-Limit your exposure to exhaust and chemi­
cals to as short a time as possible

A WARNING
-California Proposition 65 Warning:
-Engine exhaust, some of its constituents,
and certain vehicle components contain or
emit chemicals known to the State of Cali­
fornia to cause cancer and birth defects and
reproductive harm . In addition, certain flu­
ids contained in vehicles and certain prod­
ucts of component wear contain or emit
chemicals known to the State of California
to cause cancer and birth defects or other
reproductive harm.
- Battery posts, terminals and related acces­
sories contain lead and lead compounds,
chemicals known to the State of California
to cause cancer and reproductive harms.
Wash hands after handling.
(D Note
When filling fluids, be sure not to mix the flu­
ids up. Otherwise severe malfunctions and en­
gine damage will occur.
@ For the sake of the environment
You should regularly check the ground under
your vehicle in order to detect leaks quickly. If
there are visible spots from oil or other fluids, bring your vehicle to an authorized Audi deal­
er or authori zed Audi Service Facility to be
checked.
