Important safety instructions on
monitoring the Advanced Airbag System
A WARNING
- If the status of the Adva need A irbag Sys­
tem has changed wh ile the vehicle is
moving, the
PASSENGER AIR BAG OFF
light b links for about 5 seconds to catch
the driver's attent ion. If this happens, al­
ways stop as soon as it is safe to do so
and check the steps described above.
- If the PASSENGER AIR BAG OFF light
does not go off when an adu lt who is not
very small is sitting on the front passen ­
ger seat after taking the steps described
above, make sure the adult is properly
seated and restrained at one of the rear
seating pos it ions . Have the a irbag sys­
tem inspected by your authorized Audi
dealer before transpo rting anyone on the
front passenger seat .
A WARNING
An airbag system that is not funct ioning
prope rly cannot provide supplemental p ro­
t e ction in a fron tal crash.
- If the airbag indicato r light comes on, it
means that the re may be somet hing
wrong with the Advance d Ai rb ag Sy stem .
It is possible that the airbag will inflate

when it is not supposed to, or will not in­
flate when it sho uld.
- Have the airbag system inspected imme­
diate ly by you r Audi dealer.
A WARNING
-If the front airbag inflates, a child without
a child restraint, or in a rearward-facing
chi ld safety seat, or in a forward-facing
chi ld restraint that has not been properly
installed w ill be seriously injured and can
be killed.
- Even tho ugh your vehicle is equipped
wit h an Advanced A irbag System, make
certain that all children, espe cially 12
yea rs and younger, alw ays ride on the
back seat properly rest rained for their
age an d size .
- Always install forward o r rear-facing
child seats on the rear sea t - even with
an Advanced Ai rbag System.
- If you m ust install a rearw ard-fa cing
child seat on the front passenger seat
because of exceptional circ umstances
and the PASSENGER AIR BAG OFF light
does not appear and stay on, immediate­ ly install the rear-facing child seat in a
rea r seat ing pos ition and have the airbag
system inspected by your Audi dealer .
- If, in exceptiona l circumstances, you
must install a forward-fac ing ch ild re­
straint on the front passenger seat, al­
ways move the sea t into its rearmost po­
s ition in the seat 's fore and aft adjust­
men t range, as far away from the airbag
as poss ible . The backrest must be ad just ­
ed to an upright pos ition. Make su re that

Repair, care and disposal of the airbags
Parts of the a irbag system are installed at
many different places on your Audi. Installing,
removing, servicing or repairing a part in an
a rea of the vehicle can damage a part of an
airbag system and prevent that system from
working properly in a co llision.
There are some important things you have to know to make sure that the effect iveness of
the system will not be impaired and that dis­
carded components do not cause injury or po l­
lute the environment.
A WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal in­
jury and death by preventing an airbag from deploy ing when needed or deploying
an airbag unexpectedly:
- Never cover, obstruct, or change the steering wheel ho rn pad or airbag cover
or the instrument pane l or modify them
in any way .
- Never attach any objects such as cup
holders or telephone mountings to the
surfaces covering the airbag units.
- For cleaning the horn pad or instrument
pane l, use only a soft, dry cloth or one
moistened w ith plain water. Solvents or
cleaners cou ld damage the airbag cover
or change the stiffness or strength of the material so that the airbag cannot de­
ploy and protect properly.
- Never repair, adjust, or change any parts
of the airbag system.
- All work on the steering wheel, instru­
ment panel, front seats or electr ica l sys­
tem (including the installation of audio
equ ipment, cellu lar telephones and CB
radios, etc .) must be performed by a
qualified technic ian who has the training
and specia l equipment necessary.
- For any work on the airbag system, we strongly recommend that yo u see your
author ized Audi dealer or qualif ied work­
shop.
- Never modify the front b umper or parts
of the vehicle body.
- Always make sure that the s ide airbag
can inflate without inte rfe rence:
- Never install seat covers or rep lace­
ment upholstery over the front seat­
backs that have not been specifically
approved by Audi.
- Never use additional seat c ushions that
cover the areas where the side airbags
inflate.
- Damage to the orig inal seat covers or
to the seam in the area of the side a ir­
bag module must a lways be repaired
immediately by an author ized Audi
dealer .
- The airbag system can deploy on ly once.
After an a irbag has been deployed, it
must be replaced w ith new replacement
pa rts des igned and app roved especially
for your Aud i model version. Replace­
men t of comple te airbag systems or air­
bag components must be performed by
qua lified wor kshops only . Make sure that
any airbag service action is entered in
your Aud i Warranty
& Maintenance book­
let under
AIRBAG REPLACEMENT RE­
CORD.
- For safety reasons in severe accidents,
the alternator and starter a re separated
from the veh icle battery with a pyrotech-
n ic circuit inte rrupter . ..,.

-Work on the pyrotechnic circu it inter­
rupter must on ly be performed by a
qualified technic ians who have the ex­
perience, information and special tools necessary to perform the work safely.
- If the veh icle or the circuit interrupter
is sc rapped, all applicable safety pre­
cautions must be followed.
@) For the sake of the environment
Undep loyed airbag modules and preten­
sioners might be classified as Perchlorate Mate rial -special handling may apply, see
www.dtsc.ca .gov/haza rdo uswaste/per­
chlorate. When the vehicle or parts of the
restrai nt system inclu ding airbag modules
a nd safety bel ts w ith pretens ioners are
scrapped, a ll applicable laws and regula ­
tions must be observed. Your authorized
Aud i dea ler is familiar w ith these require­
ments and we recommend that you have
your dea ler perform this serv ice for you.
Other things that can affect Advanced
Airbag performance
C hanging the vehicle's suspension system can
ch ange the way that the Advanced A irbag Sys­
tem pe rforms in a crash. For example, us ing
tire-rim combinations not app rove d by Audi,
lowe ring the vehicle, changing the stiffness of
the suspension, incl uding the springs, suspen­
sion struts, shock absorbers etc. can change
the forces that are measured by the a irbag
se nsors and sent to the electron ic control
un it . Some suspension changes can, for exam­
p le, increase the force levels measured by the
se nsors and make the airbag system deploy in
crashes i n w hich it would not dep loy if the
ch an ges had not been made. Ot her kinds of
cha nges may reduce the force levels meas ­
ured by the sensors and prevent the airbag
from deploying when it shou ld.
The senso rs in the safety belt buckle fo r th e
d river and front passenger seat tell the elec ­
tronic control module if the safety belt is
l atched or not. If the safety belt is being used,
the front airbag will deploy at a slightly high-
A irba g sy stem 159
er rate of vehicle deceleration than i f the safe­
ty belt is not being used. Therefore, in a par ­
ticu lar collis ion, it is possible t hat an airbag
will not deploy at a seating pos ition where the
safety belt is be ing used but w ill inflate at the
position w here the safety belt is not be ing
used. It is impo rtant that noth ing interfere
with the safety be lt b uckles so that the sen­
sors can send the cor rec t info rmation abou t
sa fe ty belt use to the elec tronic con trol un it.
_&. WARNING ~-
Changing the vehicle's suspension includ-
ing use of unapprove d tire -rim combina ­
tions can change Advanced Airbag per­
formance and increase the risk o f serious
personal injury in a crash.
- Never install s uspension components
that do not have the same performance
characteristics as the components origi­
na lly installed on your vehicle .
- Never use tire-rim combinations that
have not been approved by Audi.
Knee airbags
Description of knee airbags
Appl ies to vehicles: wi th knee airbags
The knee airbag system can provide supple­
mental prot ection to properly r estrain ed
front seat occupants.
Fi g. 14 8 Drive r's airbag
T he driver knee airbag is i n the instrument
panel underneath the steering wheel
i=> fig . 148, the airbag for the passenger is at
about the same height in the instrument pan-
el underneath the glove compartment . ..,_

160 Airbag sys te m
The knee airbag offers additiona l protect ion
to the driver's and passenger's knees and up­ per and lower thigh areas and supp lements
the protect ion provided by the safety belts.
I f the front airbags deploy, the knee airbags
a lso deploy in frontal co llisions when the de ­
p loyment threshold stored in the contro l unit
is met
c:> page 152, More important things to
know about front airbags.
In addition to their normal safety function,
safety belts he lp keep the driver or front pas­
senger in posit ion in a frontal collis ion so that
the airbags can prov ide supplemental protec­
tion .
The airbag system is not a subst itute for your
safety belt. Rather, it is part of the overall oc­
cupant restraint system in your veh icle. Al­
ways remember that the airbag system can
only help to protect you if you are wearing
your safety be lt and wear ing it properly . Th is
is why you shou ld always wear your safety
be lt, not just because the law requires yo u to
do so
<:> page 133, General notes.
The safety belt buck le for the dr iver and front
seat passenge r have switches that te ll t he a ir­
bag control mod ule if the safe ty belt is being
used or no t. If the safety be lt is being used,
the knee airbag will deploy at a slightly higher rate of deceleration than if the belt is not be­
ing used. Therefore, in a partic ular collision, it
is possible that an airbag will not deploy at a
seating position where the safety belt is being used but will inflate at the position where the
safety belt is not be ing used.
Remember too, airbags will deploy only once
and only in certain kinds of accidents -your
safety be lts are always there to offer protec ­
tion in those acc idents in which a irbags a re
not supposed to deploy or when they have a l­
r eady deployed, fo r example whe n your veh i­
cle strikes or is str uck by another after the
first coll is ion .
This is just one of the reasons why an a irbag is
n ot a substitute for the safety belt. The airbag
sys tem works mos t effective ly when used wi th the safety be
lts. Therefore, always wear yo ur
safety be lts correct ly .
It is important to remembe r that w hile the
s u pplement al knee airbag system is designed
to reduce the likelihood of ser ious inju ries,
other injuries, for example, swelling, bruising,
minor ab rasions and friction b urns can a lso
occur when an airbag inflates.
The knee airbag sy stem basically consist s
of:
-The e lectronic control module
- Two inflatable ai rbags (airbag and gas gen -
erator), one for the driver and one for the
front passenger
- The airbag indicator lig ht in the instrument
pane l
The knee airbag system will not deploy:
-when the ignit ion is swit ched off
- in frontal collisions when the deceleration
measured by t he control un it is too low
- in side co llisions
- in rear-end col lisions
- in rollovers
- in the event of a system malfunction (warn-
ing/ind icator light is on)
<:> page 18.
A WARNING
-Safety belts and the airbag system can
only provide protection when occupa nts
are in the proper seating position
<:>pag e 152 .
- If the airbag ind icator light comes when
the vehicle is be ing used, have the sys­
tem inspected immediate ly by you r au­
thori zed A udi dealer. The airbag may not
wo rk p roperly when the vehicle a ccele ra­
tion in a side col lision is high enough to
deploy the airbag . See also

How knee airbags work
Applies to vehicles: with knee airb ags
The risk of injury to the leg area can be re­
duced by fully inflated knee airbags.
Fig. 149 Inflated airbags protecting in a frontal coll i­
sio n
The knee airbag system has been designed so
that the airbags for the driver and front pas­
senger deploy in certain but not all frontal
collisions .
If the front airbags deploy, the knee airbags
also deploy in frontal collisions when the de­ ployment threshold stored in the control unit
is met .
When the system deploys, the airbags fill
with a propellant gas, and inflate between the lower part of the instrument panel and the
driver and the lower part of the instrument panel and the front passenger¢
page 152,
fig. 146.
Although they are not a soft pillow, they can
"cush ion" the impact and in this way they can
help to reduce the risk of injury to the lower
extremities.
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 im­
portant for occupant safety that nothing
should be in their way when they deploy.
Fully inflated airbags in combination with
properly worn safety belts slow down and lim­
it the occupant's forward movement and help
to reduce the risk of injury.
Airbag system 161
Important safety instructions on the
knee airbag system
Applies to vehicles: wit h knee airbags
Airbags are only supplemental restraints . Al­
ways 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.
_&. WARNING .. -
An inflating knee airbag can cause serious injury. Wearing safety belts incorrectly and
imprope r 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 a re seated too close
to any of the airbag locations. When ad­
justing their seat positions, it is impor­
tant 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/instru­
ment panel.
- 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 wearing your safety belt . The risk in­
creases even more should the airbag de­
ploy.
- Always make sure that the knee airbag
can inflate without interference. Objects
between you and the airbag can increase
the risk of injury in an accident by inter­
fering 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

162 Airbag system
of the passenger seat. If the airbag de­
ploys, this can resu lt in serious or fata l
injuries.
- Never carry objects of any kind in the
footwell area in front of the driver's or
passenger's seat. Bulky objects (shop­
p ing bags, for examp le) can interfere
with or p revent proper dep loyment of
the airbag . Small objects can be
thrown through the vehicle i f the a ir­
bag deploys and injure you or yo ur pas­
sengers.
- Make sure there are no cra ck s, deep
scratches or ot her damage in the area of
the instrument pane l where the knee air­
bags are located .
- If children are incorrect ly sea ted, their
risk of inj ury i ncreases in a collision

Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained occupants.
Fi g. 150 Side a irbag loca tion in the dr iver 's seat
The s ide airbags are lo cated i n the sides of the
front seat backrests<=>
fig . 150 and the rear
backrest facing the doors. They are identified
by the word "AIRBAG" .
The s ide airbags installed for the front seating
positions have been designed a nd cer tified to
he lp reduce the risk of injury that can be
caused by airbags when they inflate, particu ­
larly when the occupant sitting next to it is
not seated properly. The side airbag for the
front passenger seat can be used with proper- ly installed child restraints. Please be sure to
read the important information and warnings
whenever using a child restraint in a vehicle:
Safety be lts <=>
page 133, Airbag system
<=>page 142, Child safety <=> page 168.
The side airbag system ba sicall y consi st s o f:
- t he ele ctron ic cont ro l modu le and external
side impact sensors
- t he two a irbags located in the s ides of the
front backrests and the two a irbags* located
in the rear backrest
- the airbag warning light in the ins trument
cl uster.
The airbag system is mon itored electronically
to make ce rtain that it is functioning p roperly
at all times. Each time you switch on the ign i­
t io n, the airbag system ind icator light will
come on for a few seconds (se lf diagnostics) .
The side airbag system supplements the safe­
ty be lts and can he lp to red uce the risk of in­
j u ry to the driver's, front and rear passenger's
u pper torso on the side of the veh icle that is
struck in a side collision. The airbag dep loys
only in side impacts and only when the vehicle
acce lerat ion reg istered by the control unit is
high enough. If this rate is be low the refer­
ence value programmed into the control unit,
the side airbags will not be triggered, even
though the car may be badly damaged as a re­ su lt of the collision .
It is not possib le to de­
fine an airbag triggering range th at will cover
every possib le ang le of impact, s ince the cir ­
cumstances will vary cons iderably between
one collision and another. Important factors
include, for example, the nature (hard or soft)
of the impacting object, the angle of impact,
vehicle speed, etc.
<=> page 164 , Important
safety instructions on the side airbag system .
Aside from their normal safety function, safe­
ty belts work to help keep the driver or front
passenger in position in the event of a side
collision so that the side airbags can provide
protection.
The airbag system is
not a substitute for your
safety belt. Rather, it is part of the overall oc-
cupant restra int system in your vehicle . .,,.
