Important safety instructions on
monitoring the Advanced Airbag System
A WARNING
- If the status of the Adva need A irbag System
has changed wh ile the vehicle is mov ing, the
PASSENGE R AIR B AG OFF light blinks for
about 5 seconds to catch the driver's atten­
t ion. If this happens, a lways stop as soon as
it is safe to do so and check the steps descri­
bed above.
- If the PASSENGER AIR BAG OFF light does
not go off when an adul t who is not very
small is sitt ing on the front passenger seat
after taking the steps described above,
make sure the adult is properly seated and
restra ined at one of the rear seating posi­
t ions. Have the airbag system inspected by
your authorized Aud i dealer before trans­
porting anyone on the front passenger seat.
A WARNING
An airbag system that is not funct ion ing prop­
erly cannot p rovide supplemental p rotection
in a frontal crash.
- If the airbag indicator light
r:::;, page 18
comes when the vehicle is being used, have
the system inspected immediate ly by yo ur
authorized Aud i dealer. It is possible that
156
the airbag will inflate when it is not sup­
posed to, or will not inf late when it should.
A WARNING
If the front a irbag inflates, a ch ild without a
chi ld restraint, or in a rearward-facing child
safety seat, or in a forward-fac ing ch ild re­
stra int that has not been properly instal led
will be ser iously injured and can be killed .
- Even though you r vehicle is equipped with
an Advanced A irbag System, make certain
that a ll children, espec ia lly 12 years a nd
younge r, always ride on the bac k sea t prop­
erly rest rained for thei r age and s ize.
- Always install fo rwa rd o r rea r-facing child
seats on the re ar seat -even w ith an Ad­
vanced Ai rbag System.
- If you must install a rea rwa rd-facing child
seat on the fron t passenge r seat bec ause o f
except ional circumstances and the
PASSEN­
GER AIR BAG OFF
light does not appear and
stay on, immediate ly install the rear-facing
child seat in a rear seat ing pos ition and have
the airbag system inspected by your Audi
dea ler.
- If, in exceptional circumstances, you must
install a forward-facing child restraint on
the front passenger seat, always move the
seat into its rearmost position in the seat's
fore and aft ad justment range, as far away
from the a irbag as poss ible. The back rest
m ust be adjus ted to an upr ight position.
Ma ke sure that the
PASSENGER AIR BAG
OFF
li ght 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 afte r taking the steps
described above, make sure the adult is
properly seated and restra ined at one of the
rear sea ting posit ions.
- Have the airbag system inspected by your
Aud i deale r before transporting anyone on
the front passenge r 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
PA SSENGER
A IR BAG OFF
light will stay on.
Repair , care and disposal of the airbags
Parts of the a irbag system are installed at many
d ifferent p laces on your Aud i. Installing, remov­
ing, servic ing o r repa iring a part in an area of the
vehicle can damage a part of an airbag system
and p revent that system from working properly
in a co llision.
There are some important things you have to
know to make su re t hat the effectiveness of the
system w ill not be impaired and that discarded
components do not cause injury or pollute the
environment .
A WARNING
Improper care, serv icing and repa ir proce­
dures can increase the r isk 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 a irbag cover or the in­
strument panel or mod ify them in any way.
- Never attach any objects such as cup holders or te lephone mountings to the su rfaces cov­
er ing the airbag units.
- For cleaning the ho rn pad or instrument
pane l, use on ly a soft, dry cloth or one mois­
tened with plain water. Solvents or cleaners cou ld damage the a irbag cover or change
the stiffness or strength of the mater ial so
that the airbag cannot dep loy and protect
properly.
- Never repair, adjust, or change any parts of
the airbag system.
- All work on the steering wheel, instr ument
pane l, front seats or electrical system (in ­
cluding the installation of audio equipment,
cellu lar telephones and CB rad ios, etc.)
must be performed by a qualified technician
Airb ag sys tem
who has the t raining and spec ial equ ipment
necessary.
- For any wo rk on the airbag system, we
strong ly recommend that you see yo ur au­
thorized Audi dealer or qualified workshop.
- Never modify the front b umper or parts of
the vehicle body.
- Always make sure that the side a irbag can
inflate w ithout interference:
- Never ins tall seat covers or replacement
u pholste ry ove r the front seatbacks that
have not been specifica lly approved by
Audi.
- Never use addi tional seat cushions that
cove r the areas where the side airbags in­
flate.
- Damage to the orig inal se at cove rs or to
the se am in the area of the s ide airbag
module must a lways be repaired immedi­
ate ly by an authorize d Aud i dealer.
- The airb ag system can deploy on ly on ce. Af­
ter an airbag has been deployed, it must be
replaced with new replacement parts de­
signed and approve d espec ially for your
Aud i model version. Replacement of com­
p lete airbag systems or airbag components
m ust be performed by qualified workshops
only . Make sure that any airbag service ac­
tion is entered in you r A udi Warranty
&
Maintenance boo klet under AIRBAG R E­
PLAC EM ENT R ECORD.
- For safety reasons in severe accidents, the
alternator and starte r are separated from
the vehicle ba tte ry with a pyro te chnic cir cui t
interrupter.
- Work on the pyrotechnic c ircuit interrupt­
er must on ly be performed by a qualif ied
technic ians who have the exper ience, in­
format ion and specia l tools necessa ry to
perfo rm the wor k safely.
- If the vehicle or the circuit interr upte r is
scrapped, all applicable safety p recautions
must be followed.

Airbag system
@ For the sake of the environment
Undeployed airbag modu les and pretension­
ers might be classified as Perchlorate Materi­
al -special handling may apply, see
www.dtsc.ca.gov/hazardouswaste/perchlo­
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
service for you.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
cha nge the way that the Advanced Airbag System
pe rforms in a crash. For example, using tire-r im
comb inat ions not approved by Audi, lower ing the
veh icle, changing the stiffness of the suspens ion,
including the spr ings, 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 deploy if
the changes had not been made. Other ki nds of
changes may reduce the force levels measured by
the sensors and prevent the airbag from deploy­
ing when it should .
A WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced A irbag 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
teristics as the components originally insta l­
led on your veh icle.
- Never use tire-rim comb inations that have
not been approved by Audi.

Knee airbags
Description of knee airbags
App lies to vehicles: with knee airbags
The knee airbag system can provide supplemen­
tal protection to properly restrained front seat
occupants.
Fig. 160 Driver 's knee airbag
The driver knee airbag is in the instrument panel
underneath the steering whee l
¢fig. 160, the
airbag for the passenger is at about the same
height in the instrument panel underneath the
glove compartment.
The knee airbag offers additiona l protection to
the driver 's and passenger's knees and upper and
lower thigh areas and supplements the protec­
tion provided by the safety belts.
If the front airbags deploy, the knee airbags a lso
deploy in frontal collisions when the deployment
threshold stored in the control unit is met
c> page 151, 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
position in a frontal collision so that the airbags
can provide supplemental protection .
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 wear ing your safety belt
and wearing it p roperly. This is why you shou ld
always wea r your safety be lt, not just because
the law requires you to do so
c> page 134, Gener-
al information. ..,..

Remember too, airbags will deploy only once and
only in certain kinds of accidents -your safety
belts are always 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 your vehicle strikes or is struck by
another after the first collis ion.
This is just one of the reasons why an airbag is
not a substitute for the safety belt. The airbag
system works most effectively when used with
the safety belts. Therefore, always wear your
safety belts correct ly .
It is important to remember that while the sup­
plemental knee air bag system is designed to re­
duce the likelihood of serious injuries, other inju­
ries , for example, swelling, bruising and minor
ab rasions and friction burns can also occur when
an airbag inflates.
The knee airbag system basically consists of:
-The electronic control module
- Two inflatable airbags (airbag and gas genera-
tor), one for the driver and one for the front
passenger
- The airbag indicator light in the instrument
panel
The knee airbag system will not deploy:
-when the ignition is switched off
-in frontal collisions when the deceleration
measured by the control unit is too low
- in side collisions
- in rear-end collisions
- in rollovers
- in the event of a system malfunction (warning/
indicator light is on)
cf;> page 18.
A WARNING
-Safety belts and the airbag system can only
provide protection when occupants are in
the proper seating position
cf;> page 151.
- If the airbag indicato r light c:::> page 18
comes when the vehicle is be ing us ed, have
the system inspected immed iately by your
authorized Audi dealer. It is possible that
the airbag will inf late when it is not sup­
posed to, or will not inflate when it should.
Airbag system
How knee airbags work
App lies to vehic les : with knee airbags
The risk of injury to the leg area can be reduced
by fully inflated knee airbags .
Fig. 161 Inflated airbags protecting in a fronta l co llision
T he knee airbag system has been designed so
that the airbags for the driver and front passen­ ger dep loy in certain but not all fronta l co llisions.
If the front airbags deploy, the knee airbags also
deploy in frontal coll isions when the deployment
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
c:;> page 151, fig. 158.
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 th is takes place in the blink of an eye, so
fa st that many people don't even real ize that the
airbags have deployed. The airbags a lso 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 combination with proper­
ly worn safety belts slow down and limit the oc ­
cupant's forward movement and help to reduce
the risk of injury.

-the e lectron ic control modu le and externa l side
impact sensors
- the two airbags located in the sides of the front
backrests and the two airbags * located in the
rear backrest
- the airbag warning light in the inst rument clus-
ter.
The a irbag system is monitored electronically to
make certa in that i t is functioning properly at all
times . Each time you switch on the ignition, the
airbag system indicator light will come on for a
few seconds (self diagnostics) .
The s ide airbag system supp lements the safe ty
be lts and can help to reduce the risk of injury to
the driver's, front and rear passenger's upper tor­
so on the side of the vehicle that is struck in a
side coll is ion. The a irbag dep loys only in side im­
pacts and only when the vehicle acceleration reg­
istered by the control un it is h igh enough . If this
rate is below the reference value programmed in­
to the cont rol un it, the side a irbags w ill not be
tr iggered, even thoug h the car may be bad ly
damaged as a resul t of the collision.
It is not pos­
sib le to define an airbag tr igger ing range that
will cover every possib le ang le o f impact, since
the circumstances wi ll vary considerably between
one co llision and another. Important factors in­
clude, for example, the nature (hard or soft) of
the impacting object, the angle of impact, vehicle
speed, etc .

structions on the side airbag system.

be lt and wea ring it p roperly. This is ano ther rea­
son why you s hou ld always wear yo ur safety
be lts, not just because the law requ ires yo u to do
so

It is important to remember that wh ile the sup­
p lemental side a irbag sys tem is designed to re-
Airb ag sys tem
duce the likelihood of serious injuries, other in ju­
ries, for example, swelling, bruising, friction
burns and m inor abras ions can also be assoc iated
with deployed side airbags. Remember too, side airbags will deploy only once and only in certa in
k inds of accidents -your safety belts are a lways
there to offer protect ion.
Vehicle damage, repair costs or even the lack of
vehicle damage are not necessar ily an ind ication
of over-sens it ive or fa iled a irbag activation. In
some collisions, both front and side airbags may
inflate . Remember too, that a irbags w ill dep loy
o nl y once and only in certa in kinds of collisions -
yo ur safe ty belts are alw ays 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 io n is switched off
- in side co llisions when the acceleration meas-
ured by the sensor is too low
- in fro nt-end coll is ions
- in rear-end collisions
- in rollovers.
In some types of accidents t he front airbags, side
curtain airbags and side ai rbags may be triggered
together.
A WARNING
-- Safety belts and the airbag system will only
provide protect ion when occupants are in
the proper seat ing pos ition ¢
page 162.
-If the airbag ind icator light¢ page 18

Airbag system
below the reference value programmed into the
control unit, the side curtain airbag will not be
triggered, 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 possible angle of impact , since
the circumstances will vary cons iderably between
one co llision and another. Important factors in­
clude, for example, the nature (hard or soft) of
the impacting object, the angle of impact, vehicle
speed, etc. ¢

The airbag system is not a substitute for your
safety belt. Rather, it is part of the overa ll occu­
pant restraint system in your vehicle. Always re­ member that the airbag system can only he lp to
protect you if you are wearing your safety belt
and wear ing it properly . This is another reason
why you should always wear your safety belts ,

It is important to remember that while the s ide
curtain airbag system is designed to help reduce
the likelihood of serious injuries, other injuries,
for example, swel ling, b ruising, fr iction burns
and minor abrasions can also be assoc iated with
these airbags upon deployment . Remember too,
these airbags will deploy only once and only in
certain kinds of acc idents -your safety be lts are
always there to offer protection.
The side curtain airbag system basically
consists of:
-The electronic control module and external side
impact sensors
- The side curtain airbags above the front and
rear side windows with ejection mitigation fea ­
tures
- T he airbag indicator light in the instrument
panel
The airbag system is monito red electronically to
make certa in it is funct ion ing properly at all
164
times. Each time you switch on the ignition, the
airbag system indicator light will come on for a
few seconds (se lf diagnostics).
The side curtain airbag is not activated:
-if the igni tion is sw itched off,
- in side collisions when the acceleration meas-
ured by the sensor is too low,
- in rear-end co llisions.
A WARNING
- Safety belts and the airbag system will only
provide protection when occupants are in
the proper seating position¢
page 53, Gen­
eral information.
- If the airbag indicator light¢ page 18
comes when the vehicle is being used, have
the system inspected immediately by your
author ized 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 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.
