Important safety instructions on
monitoring the Advanced Airbag System
& WARNING
An airbag system that is not functioning properly cannot provide
supplemental protection in a frontal crash.
• If the airbag indicator light comes on, it means that there may
be something wrong with the Advanced Airbag System.
It is
possible that the airbag will inflate when it is not supposed to, or
will not inflate when it should.
• Have the airbag system inspected immediately by your autho­
r ized Audi dealer.
& WARNING
If the front airbag inflate s, a child without a child restraint, in a
rearward-facing child safety seat or in a forward-facing child
restraint that has not been properly installed will be seriously
injured and can be killed.
• Even though your vehicle is equipped with an Advanced Airbag
System, make certain that all children, especially 12 years and
younger, always r ide on the back seat properly restrained for their
age and size.
• Always install forward or rear-facing child safety seats on the
rear seat -even with an Advanced Airbag System.
• If you must install a rearward-facing child safety seat on the
front passenger seat because of exceptional circumstances and
the PASSENGER AIR BAG OFF light does not appear and stay on, immediately install the rear-facing child safety seat in a rear

seating position and have the airbag system inspected by your
authorized Audi dealer.
• A tight tether o r other strap on a rearward -facing child
restraint attached to the front pa ssenger seat can put too much
pressure on the weight -sensing mat in the seat and register more
weight than i s actually on the seat . The heavier weight regi stered
can make the system work as though an adult were on the seat
and deploy the Advan ced Airbag when it mu st be suppre ssed
causing serious or even fatal injury to the child .
• If , in exceptional circumstanc es, you must install a forward­
facing child restraint on the front passenger seat, always move
the seat into its rearmost po sition in the seat' s fore and aft adjust­
ment range, as far away from the airbag as possible . The backrest
must be adjusted to an upright position. Make sure that the PASSENGER AIR BAG OFF light comes on and stays on all the time
whenever the ignition is switched on.
& WARNING
• If the PASSENGER AIR BAG OFF light doe s 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 authorized Audi
dealer before transporting anyone on the front passenger seat .
[ i ] Tips
If the we ight-sens ing mat in the front passenger seat detects an
em pty seat, the front airbag on the passenge r side will be t urne d off,
and PASSENGER AIR BAG OFF will stay on.•

Repair, care and disposal of the airbags
Parts of the airbag system a
re insta lled at many different places on
your Audi. I nstall ing, remov ing, serv icing o r rep airi ng a pa rt in an
area of the vehicle ca n damage a part of a n airbag system and prevent
t ha t sys tem from working prope rly in a coll is io n.
Th ere are some importa nt things you have to know to ma ke sure t hat
the effectiveness of the system will not be impai red and that
dis ca rded compo nents do not cause injury or po llute t he e nvir on­
ment .
& WARNING
Improper care , serv icing and repair procedures can increase the
risk of personal injury and death by preventing an airbag from
deploying when needed or deploying an airbag unexpectedly:
• Never cover, obstruct, or change the steering wheel horn pad or
airbag cover or the instrument panel or modify them in any way .
• Never attach any objects such as cupholders or telephone
mountings to the surfaces covering the airbag units .
• For cleaning the horn pad or instrument panel, use only a soft ,
dry cloth or one moistened with plain water . Solvent s or cleaners
could damage the airbag cover or change the stiffness or strength
of the material so that the airbag cannot deploy and protect prop ­
erly.
• Never repair, adjust, or change any part s of the airbag system .
• All work on the steering wheel, instrument panel , front seats
or electrical sy stem (including the installation of audio equip­
ment, cellular telephones and CB radios, etc. ) must be performed
by a qualified technician who has the training and special equip­ ment necessary .
• For any work on the airbag system, we strongly recommend
that you see your authorized Audi dealer or qualified workshop.
• Never modify the front bumper or parts of the vehicle body . ..,_

-Airbag system ------=-~-----------------------------------
& WARNING (conti nued)
• Always make sure that the side a irbag can inflate without
interference :
- Never in stall seat covers or replacement uphol stery over the
front seatbacks that have not been specifically approved by
Audi .
- Never use addit ional se at cushions that cover the areas
where the side ai rbags inflate.
- Damage to the or iginal seat covers or to the seam in the area
of the side airbag module must always be repaired immedi­
ately by an author ized Audi dealer.
• The airbag system can be activated only on ce. After an airbag
has inflated, it must be replaced by an authorized Audi dealer or
qualified technician who has the techni cal information, t raining
and special equipment necessary.
• The airbag sy stem can be deploy ed only once. After an airbag
has been dep loyed , it must be replaced with new replacement
parts designed and approved e specially for your Audi model
version. Replacement of complete airbag systems or a irbag
components must be performed by qualified workshops onl y.
Make sure that any airbag service action is entered in your Audi
Warranty
& Maintenance booklet under AIRBAG REPLACEMENT
RECORD .
• In accidents when an airbag is deployed, the vehicle battery
separates the alternator and the starter from the vehicle electrical
system for safety reason s with a pyrotechnic circuit interrupte r.
- Work on the pyrotechnic circuit interrupter must only be
performed by a qualified dealer -risk of an accident!
- If the vehicle or the circuit interrupter is sc rapped , all appli ­
cable safety precautions must be followed.
W For the sake of the environment
Un deployed ai rbag modu les and p retensione rs might be class ified as
Perch lorate Materia l -special handling may ap ply, see
www.dts c.ca.gov/ha za rdouswas te/pe rchlorate. When the vehicle or
parts of the restraint system includ ing a irbag modu les safety belts
w it h pretensioners are s crapped, all appli cable laws and regula tions
must be observed. Your author ized Aud i dealer is familiar with these
req uiremen ts and we recommen d that you have your dealer perfo rm
this serv ice for you. •
Other things that can affect Advanced
Airbag performance
Chang ing the vehicle's suspension system can change the way that
t h e Advan ced Airbag System pe rforms in a cr ash . For e xamp le, usi ng
tire-rim combinations not app roved by Audi, lowering the vehicle,
c hang ing the stiffness o f th e suspension, incl uding the sp rings,
suspension struts, shock absorbers etc. can change the forces that
are meas ure d by the a irba g sensors and sent to the ele ct ronic contro l
unit . Some suspension changes can, fo r exam ple, increase the force
levels measured by the senso rs and make the airbag system deploy in
crashes in which i t would not deploy if the changes had no t been
ma de . Other kinds of changes may reduce the force levels meas ured
by the sensors and p revent the airbag from dep loying when it should.
T he sensors in the safety belt b uckle for the drive r and front
p as senge r se at tell the e lectroni c cont rol mo dule if the sa fe ty belt is
latched or not . If the safety belt is being used, t he front a irbag w ill
dep loy a t a s lightly h igher r ate o f vehicle decele ration t han if t he
safety belt is not be ing used . Therefo re, in a par ticular collis io n, it is
possible that an a irba g w ill not dep loy at a seating position where the
safety belt is being used but w ill inflate at the posit ion where the
safety belt is not be ing use d. It is im portant that nothing interfere
w it h t he safety belt bu ckles so that the sensors can se nd the co rrect
info rmation about safety be lt use to the electronic contro l unit.

are wearing your safety belt and wearing it properly. This is why you
should always wear your safety belt, not just because the law requires
you to do so:::::,
page 189, "General notes".
The safety belt buckle for the driver and front seat passenger have
switches that tell the airbag control module if the safety belt is being
used or not. If the safety belt is being used, the knee airbag will
deploy at a slightly higher rate of deceleration than if the belt is not
being used. Therefore, in a particular collision, it is possible that an
airbag will not deploy at a seat ing position where the safety belt is
being used but will inflate at the position where the safety belt is not
being used.
Remember too, airbags w ill deploy only once and only in certa in 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 example when your vehicle strikes or
is struck by another after the first collision .
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 correctly .
It is important to remember that while the supplemental airbag
system is designed to reduce the likelihood of serious injuries, other
injuries, for example, swelling, bruising, and minor abrasions can
also be associated with airbags.
The knee airbag system basically consists of:
• The electronic control module
• T wo inflatable airbags (airbag and gas generator), one for the
dr iver 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 turned off
• in front-end collisions when the deceleration measured by the
control unit is too low
• in s ide collisions •
in rear-end collisions
• in rollovers
• in the event of a system ma lfunction (warning/indicator light illu­
m ina ted):::::,
page 14.
& WARNING
• Safety belts and the airbag system can only provide protection
when occupants are in the proper seating position :::::,
page 208.
• If the airbag indicator light comes when the vehicle is being
used, have the system inspected immediately by your authorized
Audi dealer. The airbag may not work properly when the vehicle
acceleration in a side collision is high enough to deploy the airbag.

Side airbags
Description of side airbags
The airbag system can provide supplemental protection
to properly restrained occupants .
Fig. 202 S ide airbag
l o cat ion
in the d rive r's
s e at
The side airbags are located in the sides of the front seat backrests
~ page 218 , fig. 202. They are identified by the word "AIRBAG".
The side airbag sy stem basicall y consists of :
• the electronic control module and external s ide impact sensors
• t he two side airbags located in t he sides o f the front backrests
• the airbag warning light in the instrument cluster.
T he airbag sys tem is moni tore d ele ct ronically to make certa in that it
is funct ioning properly at all times. Each time you turn on the igni­
t ion , the airbag system indicator light w ill come o n for a few seconds
(self diagnostics) .
The side airbag system supp lements the safety belts and can he lp to
red uce the risk of injury to the drive r's an d front passenge r's upper
torso on the s ide of the vehicle that is struck in a side collision . The
a irbag dep loys o nly in side impac ts an d only when the veh icle acceler ­
ation registered by the contro l unit is h igh eno ugh. If this rate is
below the refe rence val ue p rogrammed into the control u nit, t he side
airbags will not be triggered, eve n thoug h the car may be badly damaged as a resu
lt of the collision. It is not possib le to define an
air bag trigger ing range tha t w ill cove r eve ry poss ible an gle o f imp act,
since the circumsta nces will vary considerab ly between one collision
and another . Important factors incl ude, for example, the nature
(hard or soft) of the impact ing object, the a ngle of impact, vehicle
speed, etc.~
page 219, "Important safety instructions on the side
airbag system" .
Aside from the ir normal safety function, safety be lts work to he lp
keep the driver or fron t passenger in po sit io n in t he event of a side
collision so that the side airbags ca n provide p rotect ion.
T he a irbag system is
not a substitute for your safety be lt. Rather, it is
pa rt of the ove rall occupant res trai nt system in your veh icle. Always
remember that the side airbag system can only help to protect you if
you a re wear ing yo ur safety belt and wea ring it properly. This is
another reason why you shou ld always wear your safety belts, not just
bec ause t he law requires you to do so~
page 189, '' Genera l no tes ".
It is important to remember that while the supp lemental s ide airbag
system is designed to red uce the lik elihood o f serious injuries, other
injuries, fo r example, swe lli ng, br uis ing , and minor abras io ns can
also be assoc iated w ith deployed side airbags. Remember too, side
airbags will de ploy only once and only in cert ain kinds of acc idents -
your safety belts are a lways there to offer protection.
Vehicle dam age, re pair costs o r even the la ck of vehicle dam age are
not necessarily an ind ication of over-sensitive or failed airbag activa­
t ion. In some collisions, both front and side airbags may infla te .
Remember too , tha t airbags will de ploy only once and only in certa in
kinds of collisions -yo ur sa fety bel ts are a lways the re to offe r protec ­
tion i n those accide nts in which airbags ar e not s upposed to deploy o r
when they have already dep loyed.
The side airbag system will not deploy:
• when the ign ition is turned off
• in side co llisi ons when the accelerat ion measured by the sensor is
t oo low
• in front -end col lisions ._

• in rear-end collisions
• in rollover s.
In some types of accide nts the front a irbags a nd side a irbags may be
t rig gere d together.
& WARNING
• Safety belts and the airbag system will only provide prote ction
when occupants are in the proper seating position=> page
219 .
• If the airbag indicator light comes on when the vehicle is being
used, have the system inspected immediately by your authorized
Audi dealer. The airbag may not work properly when the vehicle acceleration in a side collision is high enough to activate the
airbag. •
How supplemental side airbags work
Side airbags deploy ins tan tly an d can help reduce the risk
o f upper torso injuries for occupants who are properly
restrained.
