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
seats on the rear seat -even with an Ad­
vanced Airbag System.
- If you must install a rearwa rd-facing child
seat on the front passenger seat because of
exceptiona l circumstances and the

OFF
light comes on and stays on all the time
whenever the ignition is switched on.
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.
(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

¢ 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

- in side co llisions
- in rear-end col lisions
- in rollove rs

- 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 ¢

The side airbags installed for the front seating
positions have been designed and certified to
he lp reduce the risk of in jury that can be caused
by airbags when they inflate, part icu larly when
the occupant sitt ing next to it is not seated prop­
erly . The side airbag for the front passenger seat
can be used with properly i nstalled child re­
straints . Pl ease be sure to read the important in­
fo rmation and wa rnings whenever using a child
r estra int in a vehicle: Safety belts

The s ide airba g syste m ba sicall y co nsis ts of :
-the e lectronic control module and external side
i mpact sensors
- the two airbags located in the sides of the front
backrests and the two a irbags* located in the
rear backrest
- the a irbag warning light in the inst rument clus-
te r.
The airbag system is monitored electron ica lly to
make certa in that it is functioning properly at all
times. Each time you switch on the ignition, the
ai rbag system indicator light will come on for a
few seconds (self d iagnost ics) .
The s ide airbag system supplements the safety
belts and can help to reduce the r isk of injury to
the dr iver's, front and rear passenger's upper to r­
so on the side of the veh icle that is struc k in a
side col lision. The airbag deploys only in s ide im­
pacts and o nly when the vehi cle acceleration reg­
is tered by the control unit is high enough . If this
rate is below t he reference value programmed in­
to the contro l unit, the side airbags will not be
tr iggered, even though the car may be badly
damaged as a result of the co llision. It is not pos­
sible to define an airbag tr igger ing range that
will cover every poss ible angle of impact, since
the circumstances wi ll vary considerably between
one co llision and another . Important factors in­
clude, for example, the nature (ha rd or soft) of
the impa cting object, the angle of impact, vehicle
speed, etc.

your safety belts are always there to offer protec­
t ion in those accidents in which airbags are not
supposed to deploy or when they have already
deployed .
The side airbag system will not deploy:
- when the ignit ion is switched off
- in side co llisions when the acceleration meas -
ured by the senso r is too low
- in front-end collisions
- in re ar-en d co llisions
- in rollove rs.
In some types of accidents t he front airbags, side
cu rtain airbags and s ide a irbags may be tr iggered

Airb ag syst em
-If the airbag indicator light ¢ page 20
comes when the vehicle is being used, have
the system inspected immediately by your
authorized Aud i dealer. It is possible that
the a irbag will inflate when it is not sup·
posed to, or w ill not inflate when it should.
How supplemental side airbags work
Side airbags deploy instantly and can help re·
duce the risk of upper torso injuries for occu­
pants who are properly restrained.
F ig. 135 S ide impact protection: inflated s ide airbags
When the system is triggered, the airbag is fi lled
with prope llant gas and breaks thro ugh a seam in
the seat surface area marked "AIRBAG". It ex­
pands between the side trim pane l and the pas­
senger . In order to help prov ide th is additional
protection, the side airbag must i nflate within a
fraction of a second at very high speed and with great force. The supplemental side airbag cou ld
inju re you if your seating pos ition is not prope r or
upright o r if item s are located in the area where
the supplemental side airbag expands . This ap ­
plies especially to children
c::> page 172, Child
safety .
Supplemental side airbags inflate be ­
tween the occupant and the door pane l on the
side of the vehicle that is struck in certain side
collis ion¢
fig. 135 .
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 upper part
of the body.
A fine dust may develop when the airbag deploys.
This is normal and does not mean there is a fire
in the vehicle.

Important safety instructions on the side
airbag system
Airbags are only supplemental restraints . Always
properly wear safety bel ts and ride in a proper
seating position .
There is a lot that you and your passengers must
k now and act accordingly to help the safety bel ts
and airbags do their job to provide supp lemental
protection.
_& WARNING
-
An inflating side airbag can cause serious or
fata l injury. Improperly wear ing safety be lts
and improper seating positions increase the
risk of serious personal injury and death
whenever a vehicle is being used.
- In order to reduce the risk of injury when
the supplemental side airbag inflates:
- Always sit in an upright position and never
l ean again st the area where the supple­
mental s ide airbag is located .
- Never let a child or anyone else res t the ir
head against the side tr im panel in the
area where the supplemen tal side airbag
inflates .
- Always make sure tha t safety be lts are
worn correctly,
- Do no t let anyone s itting in the fron t seat
p ut their hand or any other parts of their
body out of the window.
- Always m ake sure that the s ide airb ag can

Side curtain airbags
Description of side curtain airbags
The side curtain airbag system can provide sup­
plemental protec tion to properly restrained oc­
cupants.
Fig . 1 36 Side curtain a irbags , driver 's side: side cu rta in air ­
bag locat ion
The side curtain airbags are located on both sides
of the inter ior above the front and rear side w in­
dows

"AIRBAG" on the windshield frame and the cen­
te r roof pi llar .
The side curtain airbags conta in features that
provide ejection mitigation to help prevent vehi­
cle occupants or parts of their bodies from being
completely or partially ejected from the vehicle

registered by the cont ro l unit is high enough. If
this rate is below the reference va lue program­
med into the control unit, the s ide curtain airbag
will not be triggered, even though the car may be
badly damaged as a result of the collision .
It is
not possib le to define an airbag triggering range
that will cover every possible angle of impact ,
since the circumstances will vary considerab ly be­
tween one col lis ion and another. Important fac­
tors include , for example , the nature (hard or
soft) of the impacting object, the angle of im­
pact , vehicle speed, etc.

The airbag system is monitored electronically to
make certain it is functioning properly at all
times . Each time you sw itch on the ign ition, the
airbag system ind icator light will come on for a
few seconds (self diagnostics).
The side curtain airbag i s not acti vat ed :
- if the ign ition is switched off,
- in side collisions whe n the accelera tion meas-
