seating position and have the airbag system inspected by your
authorized Audi dealer.
• A tight tether or other str ap on a rearward-fac ing child restr aint
attached to the front pas senger seat can put too much pressure
on the weight-sensing mat in the seat and reg ister more weight
than i s actually on the seat. The heavier weight registered can
make the system work as though an adult were on the seat and
deploy the Advanced Airbag when it must be suppressed causing
s erious or even fatal injury to the child .
• If, in exceptional circumstances , you mu st in stall a forward ­
fac ing child restra int on the front passenger seat , always move the
seat into its rearmost position in the seat's fore and aft ad just ­
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 stay s on all the time
whenever the ignition is switched on .
& 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 authorized Audi
dealer before transporting anyone on the front passenger seat .
[ i ] Tips
If the weight -sensing mat in the front passenger seat detects an
e mp ty seat, the fro nt air b ag on the pa ssenge r sid e will be t urned
off, and the PASSENGER AIR BAG OFF l ight will stay on .

Repair, care and disposal of the airbags
Parts of the airbag system are insta lled at many different places on
your Au di. In stal lin g, re moving, ser vic in g or re pair in g a part in an
area of the vehicle can damage a part of an a irbag system and
pre ven t that system from wo rki ng p rope rly in a co llision .
There are some important things you have to know to make sure
that the effectiveness of the system will not be impai red an d that
d iscarded co mponents do not cause inju ry or po llute t he e nv iron ­
ment .
& WARNING
Improper care , servicing 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 obje cts su ch as cup holders 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 moi stened with plain water . Solvents or cleaners
c ould 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 parts of the airbag system.
• All work on the steering wheel , instrument panel , front seats or
electrical system (including the installation of audio equipment ,
c ellular telephones and CB radios , etc .I must be performed by a
qualified technician who has the training and special equipment
necessary .

using tire -rim combinations not approved by Audi, lowering the
vehic le, c hanging the st iff ne ss of th e susp ens ion , incl udi ng the
spr ings, suspension struts, s hock absorbers etc . ca n chan ge the
forces that are mea su red by the air bag sensors and sent to the elec ­
tronic control unit. Some suspension chan ges can, for examp le, increase the force levels
measured by the sensors and make the
airbag sys te m d eploy in c ras hes i n wh ich i t wou ld not d epl oy i f the
changes had not been made. Other kinds of changes may reduce

& WARNING
Changing the vehicle' s suspension including use of unapproved
tire -rim combinations can change Advanced Airbag performan ce
and increase the risk of serious personal injury in a crash.
• Never install suspension components that do not have the
same performance characteristics as the components originally
installed on your vehi cle .
• Never use tire -rim combinations that have not been approved
by Audi.
& WARNING
Items stored between the safety belt buckle and the center
console can cause the sensors in the buckle to send the wrong
information to the electronic control module and prevent the
Advanced Airbag System from working properly .
• Always make sure that noth ing can interfere w ith the safety
belt buckles and that they are not obstructed.

<£> For the sake of th e environm ent
Undeployed airbag modules and pretensioners might be classified
as Perchlorate Material -special handling may apply, see
www.dtsc.ca.gov/hazardouswaste/perchlorate . When the vehicle or
parts of the restraint system including airbag modules and safety
belts with pretensioners are scrapped, all applicable laws and regu­
lations must be observed . Your authorized Audi dealer is familiar
with these requirements and we recommend that you have your dea ler perform this service for you. •
Side airbags
Description of side airbags
The airbag system can provide supplemental protection
to properly restrained occupants.
Fig. 143 Si de air bag
l oc ation in th e dri ver's
seat
The s ide airbags are located in the s ides of the front seat backrests
=> fig. 143 and the rear backrest * facing the doors. They are identi ­
fied by the word "AIRBAG".
T he sid e air bag sy stem b asica lly co nsis ts of :
• the electronic control module and external side impact sensors
• the two side airbags located in the sides of the front backrests
Safety first
Airb ag sy ste m
• two rear side airbags (as an ordered option)
• the airbag warning light in the instrument cluster.
The airbag system is monitored e lectronically to make certain that
it is functioning properly at all times. Each time you turn on the igni ­
tion, the airbag system indicator light will come on for a few seconds (self diagnostics).
The side airbag system supplements the safety be lts and can help
to reduce the risk of injury to the driver's, front and rear*
passenger's upper torso on the side of the vehicle that is struck in a
side collision . The airbag dep loys on ly in side impacts and only
when the vehic le acceleration registered by the control unit is high
enough . If this rate is below the reference value programmed into
the control unit, the side airbags will not be triggered, even though
the car may be badly damaged as a result of the collision . It is not
possible to define an airbag triggering range that will cover every
possible angle of impact, since the circumstances will vary consid­
erab ly between one collision and another. Important factors
inc lude, for examp le, the nature (hard or soft) of the impacting
object, the angle of impact, vehicle speed, etc.=>
page 163, "Impor ­
tant safety instructions on the side airbag system".
Aside from their normal safety function, safety belts work to help keep the driver or front passenger in posi tion 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 occupant restraint system in your vehicle.
Always remember that the side airbag system can only help to
pro tect you if yo u are wearing your safety belt and wearing it prop ­
erly. This is another reason why you should always wear your safety
belts, not just because the law requires you to do so=>
page 135,
"General notes".
It is important to remember that while the supplemental side airbag
system is designed to reduce the likelihood of serious injuries, other
injuries, for example, swelling, bruising, and minor abrasions can
also be associa ted with deployed side airbags. Remember too, side •

airbags will deploy only once and on ly in certain kinds of accidents
- you r sa fety belts are always there to offer protection.
Vehicle damage , repair costs or even the lack of vehic le damage are
not necessarily an indication of over -sensitive or failed airbag acti ­
vation. In some col lisions , both front and side airbags may inflat e.
Remember too, that airbags will deploy only once and only in
certain ki nds of col lis ions -your sa fety belts are always there to
o ff er prot ection in those acc idents in which airbags are no t
s u pposed to deploy or when they have already dep loyed.
The side airbag system will not deploy:
• when the ign it ion is turned off
• in side collisions when the acceleration measured by the senso r
is too low
• in fron t-end col lisio ns
• in rear- end co llisions
• in rollovers.
In some types of accidents the front airbags, side curtain airbags
and s ide ai rbag s may be trigge red together.
& WARNING
• Safety belts and the airbag system will only provide protection
when occupants are in the proper seating position=>
page 163.
• If the airbag indicator light comes on when the vehicle is being
used , have the system inspected immediately by your author ized
Audi dealer . The airbag may not work properly when the vehicle
a cceleration in a side collis ion is high enough to activate the
airbag .•

- Such objects and accessories can become dangerous projec­
tiles and cause injury when the supplemental side airbag deploys.
- Never carry any objects or pets in the deployment space
between them and the airbags or allow children or other
passengers to travel in this position .
• Always use the built-in coat hooks only for lightweight
clothing . Never leave any heavy or sharp-edged objects in the
pockets that may interfere with side airbag deployment and can
cause personal injury in an accident.
• Always prevent the side airbags from being damaged by heavy
objects knocking against or hitting the sides of the seatbacks .
• The airbag system can only be triggered once . If the airbag has
been triggered , the system must be replaced by an authorized
Audi dealership.
• Damage (cracks , deep scratches etc .I to the original seat covers

Iii-

The side curtain airbag system basically consists of:
• The electronic control module and external side impact sensors
• The side cur tain airbags above the front and rear side windows
• The airbag indicator light in the instrument panel
The airbag system is monitored electronically to make certain it is
functioning properly at all times. Each time you turn on the ignition,
the airbag system indicator light will come on for a few seconds
(self diagnostics).
The side curtain airbag is not activated :
• if the ignition is turned off,
• in side collisions when the acceleration measured by the sensor
is too low,
• in front -end collisions,
• in rear-end collisions,
• in rollovers.
& WARNING
• Safety belts and the airbag system will only provide protection
when occupants are in the proper seating position
~ page 72,
"General recommendations".
• If the airbag indicator light comes on when the vehicle is being
used, have the system inspected immediately by your authorized
Audi dealer . The side curtain airbag may not work properly even
when the vehicle acceleration in a side collision is high enough to activate the airbag. •
Safety first
Airbag system
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 restrained.
Fig. 146 Illustration of
principle: Inflated side
curtain airbags on the
left side
The side curtain airbags inflate between the occupant and the
windows on the side of the vehicle that is struck in a side collision
~ fig. 146.
When the system is triggered, the side curtain airbag is filled with
propellant gas and breaks through a seam above the front and rear
side windows identified by the AIRBAG label. In order to help
provide this additional protection , the side curtain airbag must
inflate within the blink of an eye at very high speed and with great
force. The side curtain airbag could injure you if your seating posi­
tion is not proper or upright or if items are located in the area where
the supplemental side curtain airbag inflates. This applies espe­
cially to children ~
page 167.
Although they are not a soft pillow, side curtain airbags can
" cushion" the impact and in this way they can help to reduce the risk
of injury to the head and the upper part of the body.
A fine dust may develop when the airbag deploys. This is quite
normal and does not mean there is a fire in the vehicle. •

Important safety instructions on the side
curtain airbag system
Airbags are only supplemental restraints. Always prop­
erly wear safety belts and ride in a proper seating posi­
tion.
There is a lot that you and your passengers must know and do to
help the safety belts and airbags do their job to provide supple­
mental protection.
& WARNING
Improperly wearing safety belts and improper seating positions
increase the risk of serious personal injury and death whenever a
vehicle is being used.
• Never let occupants place any parts of their bodies in the area
from which the side curtain airbags inflate.
• Always make sure that the side curtain airbags can inflate
without interference. Unsuitable accessories fitted inside the expansion range of a curtain airbag can dangerously interfere with
its function. A deploying head airbag develops enough force to
catapult any piece of add-on component out of its path of inflation
and into the passenger compartment. An occupant hit by such a
projectile can suffer serious injury or death~ page
301, "Technical
Modifications".
• Do not swivel the sun visors to the side if you have any objects
clipped onto them (for example pensl. If the airbag should deploy,
you could be injured by these objects.
• Use the built -in coat hooks only for lightweight clothing. Never
leave any heavy or sharp-edged objects in the pockets that may
interfere with airbag deployment and can cause personal injury in
an accident .
• Never use hangers to hang clothing from the hooks.
• Only use factory-installed sun shades or, in the case of shades
installed after the vehicle leaves the factory, only Audi roll -up
& WARNING (continued)
sunscreens may be used ~ page 300, "Additional accessories and
parts replacement".
• Always sit in proper seating position and wear safety belts
while traveling so that the side curtain airbags can help provide protection .
• The airbag system can only be triggered once.
If the airbag has
been triggered, the system must be replaced by an authorized
Audi dealer or qualified workshop.
• Always have work involving the side curtain airbag system,
removal and installation of the airbag components, or other
repairs performed by a qualified workshop . Otherwise the airbag
system may not work correctly.
• Never attempt to modify any components of the airbag system
in anyway. •
