Federal Motor Vehicle Safety Standard
(FMVSS) 208, as well as Canada Motor Vehicle
Safety Standard (CMVSS) 208 as applicable at
the time your vehicle was manufactured. he safe
ty belts for the seats have "pretensioners" that help to take s lack out of the belt system. The pre
tensioners are also activated by the electronic
control unit for the airbag system.
The front safety be lts also have load limiters to
help reduce the forces applied to the body in a
crash.
The airbag for the driver is in the steering wheel
hub~

There is a lot you need to know about the airbags
in your vehicle . We urge you to read the detai led
i nformation about airbags, safety belts and ch ild
safety in this and the other chapters that make
up the owner's literature. Please be sure to heed
the WARNINGS -they are extremely important
for your safety and the safety of your passengers,
especially infants and small children .
.&_ WARNING -
Never rely on airbags alone for protection.
- Even when they deploy, airbags provide only
supp lemental protection.
- Airbag work most effectively when used
with properly worn safety belts .
- Therefore, always wear your safety belts and make sure that everybody in your vehicle is
properly restrained .
.&_ WARNING
A person on the front passenger seat, espe
cially infants and small ch ildren, wi ll receive
serious injuries and can even be killed by be
ing too close to the airbag when it inf lates.
- Although the Advanced Airbag System in
-
your vehicle is designed to turn off the front
passenger airbag if an infant or a small child
is on the front passenger seat, nobody can
absolutely guarantee that deployment un
der these special conditions is impossible in
all conceivable situations that may happen
during the useful life of your vehicle.
- The Advanced Airbag System can deploy in
accordance with the "low risk" option under
the U.S. Federal Standard if a child that is
heav ier than the typical one-year old ch ild is
on the front passenger seat and the other
conditions fo r airbag deployment are met.
- Accident statistics have shown that children
are generally safer in the rear seat area than
in the front seating pos ition.
- For their own safety, all children, especially
12 years and younger, should always ride in
the back proper ly restrained for their age
and size.

Your vehicle is equipped with a front Advanced
Airbag System in compliance with Un ited States
F edera l Motor Vehicle Safety Standard 208, as
well as Canada Motor Vehicle Safety Standard
(CMVSS) 208 as applicable at the time your vehi
cle was manufactured .
The front Advanced Airbag System supp lements
the safety belts to provide additional protection
for the driver 's and front passenger's heads and
upper bodies in frontal crashes . The airbags in
f late only in frontal impacts when the veh icle de
cele ration is high enough.
The front Advanced Airbag System for the front
seat occupants is not a substitute for your safety be lts . Rather, it is part of the overall occupant re
s tra int system in your vehicle. Always remember
that the airbag system can on ly help to protect
you, if you are sitting upr ight, wear ing your safe
ty belt and wear ing it prope rly . This is why you
and your passengers must always be prope rly re
stra ined, not just beca use the law req uires yo u to
be .
The Advanced Airbag System in your veh icle has
been ce rtified to meet the "low r is k" requi re
ments fo r 3 and 6 ye ar-old children o n the pas
senger side and very sma ll adults on the drive r
side . The low risk dep loyment criteria are intend
ed to help reduce the risk of injury through inter
action with the front a irbag that can occur, for
examp le, by being too close to the steering wheel
and instrument panel when the airbag inflates .
In addition , the system has been certified to
comp ly with the "suppression" requi rements of
the Safety Standard, to turn off the front a irbag
for i nfants 12 months old and younger who are
restrained on the front passenger seat in child re
stra ints that are listed in the Standa rd
¢ page 250, Child restraints and Advanced Air
bags.
"Suppress ion" requ ires the front a irbag on the
passenger side to be turned off if:
- a ch ild up to about one year of age is restra ined
on the front passenger seat in one of the rear
facing or forward -fac ing infant restra ints listed
Airb ag sys tem
in Federal Motor Veh icle Safety Standard 208
with which the Advanced Airbag System in your
veh icle was certif ied. For a List ing of the child
restraints that were used to certify your vehi
cle's compliance with the US Safety Standard
¢ page 250,
-weight less than a threshold level stored in the
con trol un it is detected on the front passenger
seat .
When a person is detected on the front passen ger seat, weighing more than the total weight of
a chi ld that is about
1 year old restra ined in one
of the rear-facing or forward -fac ing infant re
straints (listed in Federal Motor Veh icle Safety
Standard 208 with w hich the Advanced A irbag
System in your veh icle was certified), the front
airbag on the passenge r side may o r may not de
ploy .
T he
PAS SENGER AIR BAG OFF lig ht comes o n
whe n the elect ronic control uni t detects a tota l
weight on the fron t passenger sea t th at req uires
the front airbag to be turned off . If the
PASSEN
GER AIR BAG OFF
light does not come on, the
front airbag on the passenger side has not been
turned off by the control unit and can dep loy if
the control unit senses an impact that meets the
condit ions stored in its memory .
If the total weight on the front passenger seat is
more than that of a typica l 1 year-old, but less
than the weight of a small adult, the front airbag
on the passenger s ide may deploy (the
PAS SEN
GER AIR BAG OFF
light does not come on) .
For example , the ai rb ag may deploy if :
- a small chi ld that is heav ier than a typ ica l 1
yea r-o ld child is on the front passenger seat
(regard less of whether the child is in one of the
child seats listed
¢ page 250),
- a child who has outgrown c hild restraints is on
the front passenger seat.

A WARNING
- 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.

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:
- 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.
Airbag system
-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 be activated only
once. After an airbag has inflated, it must
be replaced by an authorized Audi dealer or
qualified technician who has the technical
information, training and special equipment
necessary.
- The airbag system can be deployed only
once. After an airbag has been deployed, it
must be replaced with new replacement
parts designed and approved especially for
your Audi model version. Replacement of complete airbag systems or airbag components must be performed by qualified work-
shops only. Make sure that any airbag

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 .

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 .
240
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
The knee airbag system can provide supplemen
tal protection to properly restrained front seat
occupants.

I f the front airbags dep loy, the knee airbags also
deploy in fronta l co llisions when the dep loyment
threshold stored in the contro l unit is met
c:::> page 234, More important 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 frontal coll is ion so that the a irbags
can prov ide supplemental protect ion.
The airbag system is not a substitute for your 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 wear ing it properly . T his is why yo u should
always wear your safety belt, not j ust because
the law requires you to do
so <=> page 218, Gener
al information.
Remember too, airbags will deploy only once and
on ly in certain k inds of accidents -your safety
be lts are always there to offer protection in those
accidents in wh ich airbags are no t supposed to
deploy or w hen they have a lready dep loyed, for
examp le when your vehicle strikes or is struck by
another after the first collision .
This is jus t one of the reasons why an airbag is
not a substitute for the safety belt . The a irbag
system works most effectively when used with
the safety belts . Therefore, a lways wear your
safety belts correct ly.
It is important to remember that wh ile the sup
p lemental knee airbag system is designed to re
d uce the likelihood of serious injuries, other inju
ries, for example, swell ing, bruising and minor
abrasions and friction burns can also occur when
an airbag inf lates.
The knee airbag system basically cons ists of:
- The electronic contro l module
- T wo inf latab le airbags (airbag and gas genera-
tor), one for the driver and one fo r the front
passenger
Airb ag sys tem
- The a irbag indicator light in the instrument
panel
The knee airbag system will not deploy:
- when the ignit ion is switched off
- in fronta l co llisions when the decelerat ion
meas ured by the contro l unit is too low
- in side co llisions
- in rear-end collisions
- in rollovers
- in the event of a system malfunction (warning/
ind icator light is on)
c:::> page 23.
A WARNING
--Safety belts and the airbag system can only
provide protect ion when occupants are in
the prope r seat ing pos ition
c:::> page 234.
- If the airbag ind icator light c:::> page 23
comes when the veh icle is being used, have
the system inspected immediately by your
author ized Audi dealer.
It is possib le that
the airbag will inflate when it is not sup
posed to, or w ill not inf late w hen it should.
How knee airbags work
The risk of injury to the leg area can be reduced
by fully inflated knee airbags .
Fig. 2 35 Inflated a irbags protect ing in a fro nta l collision
The knee airbag system has been designed so
that the airbags for the driver and front passen
ger deploy in certain but not all frontal collisions .
If the front airbags deploy, the knee airbags also
deploy in frontal collis ions when the deployment
threshold stored in the control unit is met.
When the system deploys, the a irbags fi ll with a

Although they are not a soft pillow, they can
"cushion" the impact and in this way they can
help to reduce the risk of injury to the lower ex
tremities.
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 inflate
with a great deal of force and it is important for
occupant safety that nothing should be in their
way when they deploy.
Fully inflated airbags in combinat ion with proper
ly worn safety belts slow down and limit the oc
cupant's forward movement and help to reduce
t he risk of injury.
Important safety instructions on the knee
a irbag system
Airbags ore only supplemental restraints. 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 provide supplemental protection .
A WARNING
An inflating knee airbag can cause serious in
jury. Wearing safety belts incorrectly and im proper seating positions increase the risk of
serious personal injury and death whenever a
vehicle is being used.
- The knee airbag system cannot protect you
properly if you are seated too close to any of
the airbag locations. When adjusting their
seat positions, it is important that both the
driver and the front passenger keep their
upper bodies and knees at the following
minimum safe distances :
- at least 10 inches (25 cm) between the
chest and the steering wheel/instrument panel.
242
- at least 4 inches (10 cm) between the
knees and the lower part of the instru
ment panel.
- The risk of personal injury increases if you
lean forward or to the side, or if the seat is
improperly positioned and you are not wear
ing your safety belt . The risk increases even
more should the airbag deploy.
- Always make sure that the knee airbag can
inflate without interference . Objects be
tween you and the airbag can increase the risk of injury in an accident by interfering
with the way the airbag deploys or by being
pushed into you as the airbag deploys.
- Never let anybody, especially children or
animals ride in the footwell in front of the passenger seat. If the airbag deploys, this
can result in serious or fatal injuries .
- Never carry objects of any kind in the foot
well area in front of the driver's or pas
senger's seat. Bulky objects (shopping bags, for example) can interfere with or
prevent proper deployment of the airbag.
Small objects can be thrown through the
vehicle if the airbag deploys and injure you
or your passengers.
- Make sure there are no cracks, deep scratch
es or other damage in the area of the instru
ment panel where the knee airbags are lo
cated .
- If children are incorrectly seated, their risk
of injury increases in a collision
c> page 248, Child safety.

Airbag syste m
The side curtain airbag system supplements the
safety belts and can he lp to reduce the risk of in
jury for occupants' heads and upper torso on the side of the vehicle that is struck in a side colli
sion . The side curtain airbag inflates in side im
pacts and only when the vehicle acceleration reg
istered by the control unit is h igh enough . If this
rate is below the reference value p rogrammed in
to the control un it, the side ai rbags wi ll not be
tr iggered, even though the car may be bad ly
damaged as a result of the collision. It is not pos
sible to define an airbag triggering range that
will cover every poss ible ang le of impact, since
the circumstances will vary cons iderably between
one collision and another. Important factors in
clude, for example , the nature (hard or soft) of
the impacting object, the angle of impact, vehicle
speed , etc.
c:> page 246, How side curtain air
bags work .
Aside from their normal safety function, safety
belts work to help keep the driver or front pas
senger in pos it io n in the event of a collision so
that the side curtain airbags can provide protec
tion .
The airbag system is not a substitute for your 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

I t is important to remember that whi le the s ide
curtain airbag system is designed to help reduce
the likelihood of serious injuries, other injuries,
for example, swe lling, bruising, and m inor abra
sions can a lso be associated with these airbags
upon deployment. Remember too, these a irbags
w ill deploy only once and only in certa in kinds of
accide nts -your safety belts are a lways the re to
offer protection.
The side curtain airbag system basically
consists of:
- The electronic control module and external s ide
impact senso rs
246
- The side curtain a irbags above the front and
rear side windows
- The a irbag indi cator light in the instrument
panel
The airbag system is mon itored electro nical ly to
make certain it is func tioning properly at all
times. Each t ime you switch on the ignit ion, the
airbag system indicator light will come on for a
few seconds (self diagnostics) .
The side curtain airbag i s not activated:
- if the igni tion is switched off,
- in side collisions whe n the acceleration meas-
ured by the sensor is too low,
- in rear-end collisions .
A WARNING
-Safety belts and the airbag system will only
provide pro tect ion when occupants are in
t he prope r seating pos ition

How side curtain airbags work
Side curtain airbags can work together with side
airbags to help reduce the risk of head and upper
torso injuries for occupants who are properly re
strained.
