smash the child seat and child against the
backrest, center armrest, door or roof.
- Always install rear-facing child seats on the
rear seat.
- If you must install a rearward facing child
seat on the front passenger seat because of
exceptional circumstances and the
PASSEN­
GER AIR BAG OFF
light does not come on
and stay on, immediately install the rear­
facing child seat in a rear seating position
and have the airbag system inspected by
your Audi dealer.
A WARNING
Objects between you and the airbag will in­
crease the risk of injury in a crash by interfer­
ing with the way the airbag unfolds or by be­
ing pushed into you as the airbag inflates.
- Never hold things in your hands or on your
lap when the vehicle is in use.
- Never transport items on or in the area of
the front passenger seat. Objects could
move into the area of the front airbags dur­
ing braking or other sudden maneuvers and
become dangerous projectiles that can
cause serious personal injury if the airbags
inflate.
- Never place or attach accessories or other objects (such as cup holders, telephone
brackets, large, heavy or bulky objects) on
the doors, over or near the area marked "AIRBAG" on the steering wheel, instru­
ment panel, seat backrests or between
those areas and yourself. These objects could cause injury in a crash, especially
when the airbags inflate.
- Never recline the front passenger's seat to
transport objects. Items can also move into
the area of the side airbag or the front air­
bag during braking or in a sudden maneu­
ver. Objects near the airbags can become
projectiles and cause injury, particularly
when the seat is reclined.
- Never place or transport objects on the front passenger seat. Objects on the front passenger seat could cause the capacitive
sensor in the seat to signal to airbag system
Airbag system
that the seat is occupied by a person when it
in fact is not, or that the person on the seat
is heavier than he or she actually is. The
change in electric capacitance because of
such objects can cause the passenger front
airbag to be turned on when it should be off,
or can cause the airbag to work in a way that
is different from the way it would have
worked without objects on the seat.
-Always make sure that there is nothing on
the front passenger seat that will cause the
capacitive passenger detection system in
the seat to signal to the Airbag System that
the seat is occupied by a person when it is
not, or to signal that it is occupied by some­
one who is heavier than the person actually
sitting on the seat. The presence of an ob­
ject could cause the passenger front airbag to be turned on when it should be off, or
could cause the airbag to work in a way that is different from the way it would have
worked without the object on the seat.
_LD. WARNING
The fine dust created when airbags deploy can
cause breathing problems for people with a
history of asthma or other breathing condi­
tions.
- To reduce the risk of breathing problems,
those with asthma or other respiratory con­
ditions should get fresh air right away by
getting out of the vehicle or opening win­
dows or doors.
- If you are in a collision in which airbags de­
ploy, wash your hands and face with mild
soap and water before eating .
- Be careful not to get the dust into your eyes,
or into any cuts or scratches.
- If the residue should get into your eyes,
flush them with water.

- does not come on when the ignition is switched
on,
- does not go out a few seconds after you have
switched on the ignition, or
- comes on while driving.
If an airbag system ma lf u nction is detected, the
indicator light will first start flashing to catch the
driver's attention and then stay on continuously
to serve as a constant reminder to have the sys­
tem inspected immediately .
If a malfunction occurs that turns the front air­
bag on the passenger side off, the
PA SSE NGE R
A IR BAG OFF
light will come on and stay on
whenever the ignition is on.
.,&. WARNING
An airbag system that is not funct ion ing prop­
erly cannot p rovide supplemental protect ion
in a frontal crash.
- If the airbag indicato r light

comes when the vehicle is being used, have
the system inspected immediately by your
authorized Audi dealer. It is possible that
the airbag will inflate when it is not sup­
posed to, or will not inflate when it should .
.&_ WARNING
If the front airbag inflates, a child without a
child restraint, or in a rearward -facing child
safety seat, or in a forward-fac ing ch ild re­
straint that has not been proper ly installed
will be ser iously injured and can be killed.
- Even though your vehicle is equipped with
an Advanced A irbag System, make ce rtain
that a ll children, especially 12 years and
younger, a lways ride on the back seat prop­
erly restrained for their age and size.
- Always install forward o r rear-facing child

- If the PASSENGER AIR BAG OFF light does
not go out when an adult is sitting on the
front passenger seat after taking the steps
described above, make sure the adult is
properly seated and restrained at one of the
rear seating positions.
- Have the airbag system inspected by your
Audi dealer before transporting anyone on
the front passenger seat.
(D Tips
If the capacitive passenger detection system
determines that the front passenger seat is
empty, the frontal airbag on the passenger
side will be turned off, and the
PASSENGER
AIR BAG OFF light will stay on .
Repair, care and disposal of the airbags
Parts of the airbag system are installed at many
different places on your Audi . Installing, remov­
ing , 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 discarded
components do not cause injury or pollute the
environment.
A WARNING
-
Improper care, servicing and repair proce­
dures can increase the risk of personal injury
and death by preventing an airbag from de­
ploying when needed or deploying an airbag
unexpectedly:
Airbag system
-Never cover, obstruct, or change the steer­
ing wheel horn pad or airbag cover or the in­
strument panel or modify them in any way.
- Never attach any objects such as cup holders
or telephone mountings to the surfaces cov­
ering the airbag units.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one mois­
tened 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 deploy and protect
properly.
- Never repair, adjust, or change any parts of
the airbag system.
-All work on the steering wheel, instrument
panel, front seats or electrical system (in­
cluding 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 au­
thorized Audi dealer or qualified workshop.
- 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 replacement upholstery over the front seatbacks that
have not been specifically approved by
Audi .
- Never use additional seat cushions that
cover the areas where the side airbags in­
flate.
- Damage to the original seat covers or to
the seam in the area of the side airbag
module must always be repaired immedi­
ately by an authorized Audi dealer.
- The airbag system can deploy only once. Af­
ter an airbag has been deployed, it must be
replaced with new replacement parts de­
signed and approved especially for your Audi model version. Replacement of complete
airbag systems or airbag components must be performed by qualified workshops only.
Make sure that any airbag service action is
163

Airb ag syst em
entered in your Audi Warranty & Mainte­
nance booklet 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 circ uit inter rupt­
er must only be performed by a qualified
technicians w ho have the experience, in­
formation and special tools necessary to perform the work safely.
- If the veh icle or the circuit interrupter is
scrapped, a ll applicable safety precautions
must be followed.
@ For the sake of the environment
Undep loyed airbag modu les and pretension ­
ers might be classified as Perchlorate Materia l
- specia l hand ling may apply, see
www.dtsc.ca.gov/hazardouswaste/perchlo­ rate. W hen the veh icle or parts of the re­
straint system including a irbag modules and
safety belts with prete nsioners are scrapped ,
all applicable laws and regulat ions must be
observed. Your authorized A udi dealer is fa­
m iliar with the se requirements a nd we recom­
mend that you have your dealer perform this
service for yo u.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system ca n
change the way that the Advanced A irbag System
performs in a crash. For example, using t ire- rim
combinat ions not approved by Audi, lower ing the
ve hicl e, chang ing the stiffness of the suspension,
includ ing the spr ings, suspension s truts, shoc k
absorbers etc. can change the forces that are
measured by the a irbag sensors and sent to the
e lectronic control unit. Some suspension changes
can, for example, increase the force levels meas ­
ured by the sensors and make the a irbag system
deploy in c rashes in which it wou ld not deploy if
the changes had not been made. Other ki nds of
changes may reduce the force levels measured by
164
the sensors and p revent the airbag from dep loy ­
ing when it shou ld .
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
ter istics as the components origina lly instal­
led on you r vehicle.
- Never use tire-rim combinations that have
not been approved by Audi.
Knee airbags
Description of knee airbag s
Applies to vehicles: with knee airbags
The knee airbag system can provide supplemen­
tal protection to properly restrained front seat
occupants .

¢ page 158, More impor tant things to know
about front airbags .
In addition to their normal safety function, safe­
ty belts help keep the driver or front passenger in position in a fronta l co llision so that the airbags
can provide supp lemental protection.
The airbag system is not a s ubst itute for yo ur
safety belt. Rather, it is part of the overall occu­ pant restraint system in your vehicle . Always re­
member that the airbag system can only help to
protect you if you are wearing your safety belt
and wearing it properly. This is why you should al­
ways wear your safety belt, not just because the law requires you to do so~
page 140, General
notes.
Remember too, airbags will deploy only once and
only in certain kinds of accidents -your safety
be lts are a lways there to offer protection in those
accidents in which airbags are not supposed to
deploy or when they have already deployed, for
examp le when yo ur vehicle str ikes or is struck by
anothe r after the first collision .
This is just one of the reasons why an a irbag is
not a substitute for the safety belt . The airbag
sys tem works most effective ly when used with
the safety belts. Therefore, always wear your
safety bel ts correctly .
It is important to remember that whi le the sup­
p lemental knee a irbag sys tem is designed to re­
d uce the likelihood of serious i njur ies , o ther inj u­
ries, for examp le, swe lling, bruising and m inor
abrasions and friction b urns can a lso occur when
an airbag inf lates.
The kne e airbag system basically consist s of:
- T he elec tronic control mod ule
- Two inflatab le airbags (airbag and gas genera-
tor), one for the drive r and one fo r the front
passenge r
- T he airbag ind icator light in the instrument
pane l
The knee airb ag system will not deploy:
- when the ign it ion is swi tched off
- in frontal collis ions when the dece lerat ion
measured by the control unit is too low
Ai rb ag system
- in side co llisions
- in rear-end col lisions
- in rollove rs
- in the event of a system malfunction (war ning/
ind icator light is on) ¢
page 20.
,&. WARNING
-Safety belts and the airbag system can only
prov ide protection when oc cupan ts are in
the proper seating position~
page 158 .
- If th e ai rbag ind icator light 9 page 20
comes when the veh icle is being used, have
the system inspected immediately by your
authorized Audi dealer .
It is possible that
the airbag will inflate when it is not sup­
posed to, or will not inflate when it should.
How knee airbags work
Applies to vehicles: wit h knee airbags
The risk of injury to the leg area can be reduced
by fully inflated knee airbags .
Fig . 1 33 Inflated a irbags p rotect ing in a fro nta l co llision
The knee airbag system has been designed so
that the airbags for the driver and front passen­
ger dep loy in certai n but not all fronta l collisions.
If the front ai rbags dep loy, the knee a irbags also
deploy in frontal co llisions when the deployment
threshold stored in the control un it is met .
When the system deploys, the airbags fill with a compressed propellant gas, and inflate between
the lowe r part of the i nstr ument panel and the
driver and the lower part of the instrument pane l
and the front passenger ¢
page 158, fig. 130.
Although they are not a soft pillow , they can
" cushion " the impact and in th is way they can
165

Airb ag syst em
help to reduce the risk of injury to the lower ex­
trem ities.
All of this takes place in the blink of an eye, so
fast that many people don' t even realize that the
airbags have deployed. The airbags also in flate
with a great deal of force and it is important for
occ upant safety that noth ing shou ld be in their
way when they deploy.
Fully inflated airbags in combination with proper­
ly worn safety belts slow down and limit the oc­
cupant's forward movement and he lp to reduce
the risk of injury.
Important safety instructions on the knee
airbag system
Applies to veh icles: w ith kn ee a irbags
Airbags are only supplemen tal res traints. Always
wear safety belts correctly and ride in a proper
seating position.
There is a lot that you and your passengers must know and do to help the safety belts and airbags
to prov ide supplemental protection .
A WARNING
An inflating knee airbag can cause ser ious in­
jury . Wearing safety belts incor rectly and im­
prope r seating positions inc rease the risk of
ser ious persona l injury and death w henever a
vehicle is being used.
- T he knee airbag system ca nnot pro tect you
properly if you are seated too close to any of
the airbag locat ions. When adjusting their
seat positions, it is important that both the dr iver and the front passenger keep the ir
upper bodies and knees at the following
min imum safe distances:
- at least 10 inches ( 25 cm) between the
chest and the s teer ing whee l/i nstr ument
panel.
- at least 4 i nches ( 10 cm) betwee n the
knees and the lower part of the inst ru ­
ment panel.
- The r is k of persona l injury in creases i f you
lean forward or to the s ide, or if the seat is
improperly positioned and you are not wear-
166
ing your safety belt . The risk increases even
more should the a irbag deploy.
- Always make sure that the knee airbag can
inflate w ithout interference . Objects be­
tween you and the airbag can increase the r isk of injury in an accide nt by interfering
w ith the way the airbag deploys or by being
pushed into yo u as the a irbag deploys .
- Neve r let anybody, especia lly children or
anima ls ride in the footwell in front of the
passenger seat. If the airbag deploys, this
can resu lt in serious or fatal injur ies .
- Neve r carry ob jects of any kind in the foot­
well area in front of the driver's or pas ­
senger's seat. Bulky objects (shopping bags, for examp le) can interfere with or
prevent proper deployment of the airbag .
Small objects can be thrown through the
vehicle if the airbag deploys and injure yo u
or your passe ngers .
- Make sure the re are no cracks, deep scratch­
es o r othe r damage in the area of the instr u­
men t panel where the knee a irbags are lo­
ca ted .
- I f ch ildren are incorrec tly seated, their risk
of injury increases in a coll is io n
