- If you are in a collision in which airbags
deploy, wash your hands and face with
mild soap and water before eating.
- Be careful not to get the dust into your
eyes, or into any cuts or scratches.
- If the residue should get into your eyes,
flush them with water.
Monitoring the
Advanced Airbag
System
Airbag monitoring indicator light
Two separate indicators monitor the function
of the Advanced Airbag System: the airbag
monitoring indicator Light and the
PASSEN ­
GER AIR BAG OFF
light.
The Advanced Airbag System (including the
e lectronic control un it, sensor circuits and sys­
tem wiring) is monitored cont inuously to
make sure that it is functioning properly
whenever the ignit ion is on . Each t ime you
turn on the ignition, the airbag monitoring in­
d icator light
I will come on fo r a few seconds
(self diagno stics) .
The system mu st be inspected when the
indicator light
I :
- does not come on when the ignit io n is
switched on
- does not go out a few seconds after you
have swi tched on the ign ition, o r
- comes on while driving
If an airbag system malfunct ion is detected,
the ind icator light will fi rst start flash ing to
catch the driver's attention and then stay on
continuously to serve as a constant reminder
to have the system inspected immediately .
If a malfunction occurs that turns the front
a ir bag on the passenger side off, the
PAS SEN­
GER AIR BAG OFF
li ght w ill come on and stay
on whenever the ignition is on.
A WARNING
An a irbag system that is not functioning
properly cannot provide supplemental pro­
tection in a frontal crash.
- If the airbag ind icator light¢
page 16
comes when the veh icle is being used,
have the system inspected immediately
by your authori zed Audi dealer. It is pos­
sib le that the airbag will infla te when it
is not supposed to, or will not infla te
when it should .

T he PAS SENGER AIR BAG OFF light wi ll come
on and stay on to tell you w hen the front Ad­
vanced Airbag on the passenger side has been
turned off by the electron ic contro l unit. Each
t ime you turn on t he ignition, the
PASSEN ­

light will flas h for a few
seconds and:
- w ill stay on if the front passenger seat is not
occupied
- will stay on i f the re is a small chi ld or child
restraint on the front passenger seat
- will go out if the front passenger seat is oc­
cupied by an adult as registered by the
weight-sensing mat
T he
PASSENGER AIR BAG OFF light must
come on and sta y on
if the ignition is on and
- a car bed has been ins talled on the fron t
seat, or

-a rearward-facing child restraint has been
installed on the front passenger seat, or
- a forward -facing child restraint has been in­
stalled on the front passenger seat, or
- the weight registered on the front passen­
ger seat is equa l to or less than the com­
bined weight of a typical 1 year-old restrain­
ed in one of the rear-facing or forward-fac­
ing infant restraints listed in Federal Motor
Vehicle Safety Standard 208 w ith which the
Advanced Airbag System in your vehicle was
certified .
If the front passenger seat is not occupied,
the front airbag will not deploy, and the
PAS ·
SENGER AIR BAG OFF
light will stay on. Nev­
er install a rearward-facing child restra int on
the front passenger seat, the safest place for
a child in any kind of child restraint is at one
of the seating positions on the rear seat
¢ page 185, Child restraints on the front seat
- some important things to know
and
¢ page 204, Child Safety.
If the PASSENGER AIR BAG OFF light comes
on
when one of the conditions listed above is
met, be sure to check the light regularly to
make certain that the
PASSENGER AIR BAG
OFF
li ght stays on continuous ly whenever the
ignition is on. If the
PASSENGER AIR BAG
OFF
light does not appear on and does not
stay on all the time, stop as soon as it is safe
to do so and
- reactivate the system by turning the ignition
off and then turning it on again;
- remove and reinstall the chi ld restraint .
Make sure that the child restraint is properly
installed and that the safety be lt for the
front passenger seat has been correctly
routed through the child restraint as descri­
bed in the chi ld restraint manufacturer's in­
st ructio ns;
- make sure that the convert ible locking fea­
ture on the safety belt for the front passen­
ger seat has been activated and that the
sa fety belt has been pulled tight. The belt
must not be loose or have loops of slack so
that the sensor below the safety belt latch
on the seat can do its job
¢ page 214.
Airbag system 195
-make sure that things that may increase the
weight of the child and chi ld safety seat are
not being transported on the front passen­
ger seat;
- make s ure that the safety belt tension sen ­
sor is not blocked. Shake the safety belt
latch on the front passenger seatback and
forth;
- If a strap or tether is be ing used to tie the
child safety seat to the front passenger
seat, make sure that it is not so tight that it
causes the weight-sensing mat to measure
more weight than is actually on the seat.
If the PASSENGER AIR BAG OFF light still
does not come on
and does not stay on con­
t inu ously (when the ignition is switched on),
- take the child restraint off the front passen-
ger seat and install it proper ly at one of the
rear seat positions . Have the airbag system
inspected by you r authorized Aud i dealer
immed iate ly.
- move the ch ild to a rear seat position and
make sure that the child is properly restra in­
ed in a child restraint that is appropriate for
its size and age.
The
PASSENGER AIR BAG OFF light should
NOT come on when the ignition is on and an
adult is s itting in a proper seating position on
the front passenger seat. If the
PASSENGER
AIR BAG OFF
light comes on and stays on or
flashes for about 5 seconds wh ile driving, un ­
der these circumstances, make sure that:
- the adult on the front passenger seat is
properly seated on the cente r of the seat
cushion with his or her back up against the
backrest and the backrest is not reclined

198 Airbag system
@ For the sake of the environment
Undep loyed airbag modu les and preten­
sioners might be classified as Perchlorate Material -special handling may app ly, see
www.dtsc.ca.gov/haza rdouswaste/per­ chlorate. When the vehicle or parts of the
restraint system including airbag modules
and safety belts w ith pretens ioners are
scrapped, all applicable laws and regula­
tions must be observed. Your authori zed
Audi dea ler is familiar with these requ ire­
ments and we recommend that you have
your dea ler perform this service for you.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag Sys­
tem performs in a crash. For example, using
tire-r im combinations not approved by Aud i,
l owering the vehicle, changing the stiffness o f
the suspension, including the springs, s uspen­
sion struts, shock absorbers etc. can change
the forces that are measured by the airbag
sensors and sent to the electronic control
un it. Some suspension changes can, for exam­
ple, increase the force levels measured 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 kinds of
changes may reduce the force levels meas ­
u red by the sensors and prevent the airbag
from deploying when it should .
The sensors in the safety belt buckle for the
driver and front passenger sea t tell the elec­
tronic control module if the safety belt is
latched or not. If the safety belt is being used,
the front airbag will deploy at a slightly high­
er rate of vehicle deceleration than if the safe­
ty belt is not being used. Therefore, in a par­
ticular 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 being
used.
It is important that nothing interfere
with the safety belt buckles so that the sen- sors can send the correct info
rmation about
safety belt use to the electronic control unit.
.&_ WARNING
-
Changing the vehicle's suspension includ- ing use of unapproved tire-rim combina­
tions can change Advanced Airbag per­
formance 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 origi­
nally installed on your vehicle.
- Never use tire-rim combinations that
have not been approved by Audi.
&_ WARNING
--
Items stored between the safety be lt
buckle and the center console can cause
the sensors in the buckle to send the
wrong information to the e lectronic con­
trol module and prevent the Advanced Air ­
bag System from working properly.
- Always make sure that nothing can inter­
fere with the safety belt buckles and that
they are not obstructed.
Side airbags
Description of side airbag s
The airbag system can provide supplemental
protection to properly restrained occupants.
Fig. 211 Side airbag location in th e drive r's seat
The side airbags are located in the sides of the
front seat backrests
~fig. 211 and the rear
backrest* facing the doors. They are identified
by the word "AIRBAG". ....

The side a irbag syste m basicall y consists o f:
-the e lectronic control module and external
s ide impact senso rs
- the two side airbags located in the sides of
the front backrests
- two rear side airbags (as an ordered
option)
-the a irbag warning light in the in strument
cluster .
The airbag system is monitored electron ically
t o make certain that it is functioning properly
at all times . Each time you turn on the igni­
tion, the airbag system indicator l ight will
come on for a few seconds (self diagnostics) .
The s ide a irbag system supplements the safe­
ty belts and can help to reduce the risk of in­
jury to the driver's, front and rear* passeng­ er's upper torso on the side of the veh icle that
i s struck in a side collision. The a irbag dep loys
only in s ide impacts and on ly when the veh icle
acceleration registered by the control unit is
high enough. If this rate is below 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
sult of the collision. It is not possible to de­
fine an airbag trigger ing range that will cover
every possible angle of impact, since the cir­
cumstances will vary considerably between
one co llision and another. Important factors
include, for examp le, the natu re (hard o r soft)
of the impacting object, the ang le o f impact ,
vehicle speed, etc.
¢ page 200, Important
safety instructions on the side airbag system .
Aside from their normal safety function , safe­
ty belts work to he lp keep the driver or front
passenger in position in the event of a side
coll ision 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 restraint system in your vehicle . Al­
ways remember that the side airbag system
can only help to protect you if you are wear ing
your safety belt and wear ing it properly . Th is
i s another reason why you should always wear
your safety belts, not just because the law re-
A irbag system 199
quires you to do so c;> page 174, General
notes .
It is important to remembe r that w hile the
s u pplementa l side 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 deployed side airbags. Remember too,
s ide airbags will deploy only once and only in
certain kinds of accidents -your safety belts
are always there to offer protection .
Vehicle damage, repair costs or even the lack
of veh icle damage are not necessarily an indi­
cation of over -sensitive or failed airbag activa ­
t ion. In some collis ions, both front and side
airbags may inflate. Remember too, that air­ bags will deploy only once and only in ce rtain
ki nds of col lis ions -yo ur safe ty belts are al­
ways there to offer protection in those acc i­
dents in which airbags are not supposed to
deploy or when they have a lready deployed.
The side airbag system will n ot deploy:
- when t he ignit io n is tu rned off
- in side co llisions when the acceleration
meas ured by the sensor is too low
- in front-end collisions
- in rear-end collisions
- in rollovers.
In some types of accidents the front airbags,
side curtain airbags and side ai rbags may be
triggered together.
A WARNING
- Safety belts and the airbag system will
only provide protection when occupants
are in the proper seating position
¢page 200.
-If the airbag ind icator light ¢ page 16
comes when the veh icle is being used,
have the system inspected immediately
by your authori zed Audi dealer.
It is pos­
sible tha t the airbag will inflate when it
is not supposed to, or will not infla te
when it should. •
•

-Objects between you and the airbag can
increase the risk of injury in an accident
by interfering with the way the airbag
unfolds or by being pushed into you as
the airbag inflates .
- Never place or attach accessories or
other objects (such as cupholders, tele­
phone brackets, or even large, bulky
objects) on the doors, over or near the
area marked "AIRBAG" on the seat
backrests.
- Such objects and accessories can be­
come dangerous projectiles and cause
injury when the supplemental side air­
bag 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 air­
bag deployment and can cause personal
injury in an accident.
- Always prevent the side a irbags from be­
ing damaged by heavy objects knocking
against or hitting the sides of the seat­
backs.
- The airbag system can only be trigge red
once.
If the airbag has been triggered,
the system must be replaced by an au­
thorized Audi dealership .
- Damage (cracks, deep scratches etc .) to
the original seat covers or to the seam in
the area of the side airbag module must
always be repaired immediately by an au­
thorized Audi dealer .
- If children are seated improperly, their
risk of injury increases in the case of an
accident ~ page 204 , Child Safety .
- Never attempt to modify any compo­
nents of the airbag system in any way .
- In a side collision, side airbags will not
function properly if sensors cannot cor­ rectly measure increasing air pressure in ­
side the doors when air escapes through
Airbag system 201
larger, unclosed openings in the door
panel.
- Never drive with interior door trim pan­
els removed .
- Never drive when parts have been re­
moved from the inside door panel and
the open ings they leave have not been
properly closed.
- Never drive when loudspeakers in the
doors have been removed unless the
speaker holes have been p roperly
closed.
- Always make certain that openings are
covered or filled if additiona l speakers
or other equipment is installed in the inside door panels .
- Always have work on the doors done by
an authorized Audi dealer or qualified
workshop.
Side curtain airbags
Description of side curtain airbags
The side curtain airbags can provide supple­
mental protection to properly restrained oc ­
cupants .
Fig. 213 Side curta in a irbags, driver's s ide: locatio n
The side c urtain airbags are located on both
sides of the interior above the front and rear
side w indows ~fig . 213 . They ar e identified
by the word "AIRBAG" on the windshield
frame and the center roof pillar .
The side curtain airbag system supplements
the safety belts and can help to reduce the
risk of injury for occupants' heads and upper
torso on the side of the vehicle that is struck
in a side collision. The side cur tain airbag ..,.

inflates in side impacts and only when the ve­
hicle acceleration registered by the control
unit is high enough. If this rate is below the
reference value programmed into the contro l
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
circ umstances w ill vary cons iderably between
one co llision and another. Important factors
include, for examp le, the nat ure (hard or soft)
of the impacting object, the angle of impact,

tain airbags work.
Aside from their normal safety function, safe ­
ty belts work to he lp keep the driver or front

sion so that the side curta in airbags can pro­
vide protection.
The airbag system is not a substitute for your
safety belt. Rather, it is part of the overall oc­
cupant restraint system in your ve hicle. Al­
ways remember that the airbag system can
only help to protect you if you are wearing

The side curtain airbag system basically
con sists of :
-The electronic control module and external
side impact sensors
- The side curtain airbags above the front and rear side w indows - The airbag indicator light in the instrument
panel
T he airbag system is mon itore d elec tronically
to make certain i t is func tioning properly at all
times . Each t ime you turn on the ignition, the
airbag system indicator light will come on for
a few seconds (sel f diagnostics).
The side curtain airbag is not activated:
- if the ignition is turned off
- in side co llision s when the accele ration
meas ured by the sensor is too low
- in rear-end col lisions .

-Always install rear-facing child safety
seats on the rear seat.
- If you must install a rearward facing
child safety seat on the front passenger
seat in exceptional circumstances and
the
PASSENGER AIR BAG OFF light does
not come on and stay on, immediately
install the rear-facing child safety seat in
a rear seating position and have the air­
bag system inspected immediately by
your Audi dealer.
_& WARNING
If, in exceptional circumstances, you must
install a forward-facing child restraint on
the front passenger's seat:
- Always make sure the forward-facing
seat has been designed and certified by its manufacturer for use on a front seat
with a passenger front and side airbag.
- Always follow the manufacturer's in­
structions provided with the child safety
seat or carrier.
- Always move the passenger seat into its
rearmost position in the seat's fore and
aft adjustment range, as far away from
the airbag as possible before installing
the child restraint. The backrest must be
adjusted to an upright position .
- Always make sure that the
PASSENGER
AIR BAG OFF
light comes on and stays
on all the time whenever the ignition is
switched on.
(D Tips
Always replace child restraints that were
installed in a vehicle during a crash. Dam­
age to a child restraint that is not visible
could cause it to fail in another collision
situation.
Advanced front airbag system and children
Your vehicle is equipped with an "Advanced
Airbag System" in compliance with United
States Federal Motor Vehicle Safety Standard
Child Safety 205
(FMVSS) 208 as applicable at the time your
vehicle was manufactured.
The Advanced Airbag system in your vehicle
has been certified to meet the "low-risk" re­
quirements for 3- and 6-year old children on
the passenger side and small adults on the driver side. The low risk deployment criteria
are intended to reduce the risk of injury
through interaction with the airbag that can
occur, for example, by being too close to the
steering wheel and instrument panel when
the airbag inflates . In addition, the system
has been certified to comply with the "sup­
pression" requirements of the Safety Stand­
ard, to turn off the front airbag for infants up
to 12 months who are restrained on the front
passenger seat in child restraints that are list­
ed in the Standard.
Even though your vehicle is equipped with an
Advanced Airbag system, all children, espe­ cially those 12 years and younger, should al­
ways ride in the back seat properly restrained
for their age and size. The airbag on the pas­
senger side makes the front seat a potentially dangerous place for a child to ride . The front
seat is not the safest place for a child in a for­
ward-facing child safety seat. It can be a very
dangerous place for an infant or a larger child
in a rearward-facing seat .
Advanced Airbags and the weight­
sensing mat in the front seat
The Advanced Airbag System in your vehicle
detects the presence of an infant or child in a
child restraint on the front passenger seat us­
ing the weight -sensing mat in the seat cush­
ion and the sensor below the safety belt latch
on the front passenger seat that measures the
tension on the safety belt.
The weight -sensing mat measures total
weight of the child and the child safety seat
and a child blanket on the front passenger seat. The weight on the front passenger seat
is related to the design of the child restraint
and its "footprint", the size and shape of the
bottom of the child restraint as it sits on the ..,.
•
•

206 Child Saf ety
seat. The weight of a child restraint and its
"footprint" vary for different kinds of chi ld re­
straints and for the d ifferent models of the
same kind of child restraint offered by child
restraint manufacturers .
The weight ranges for the individual types, makes and mode ls of ch ild restra ints that the
NHTSA has specified in the Safety Standard
together with the weight ranges of typical in­
fants and typical 1 year-old child have been
stored in the control unit of the Advanced A ir­
bag System. When a ch ild restrai nt is being
used on the front passenger seat with a typi ­
cal 1 yea r-old chi ld, the Advanced Airbag Sys­
tem compares the weight measured by the
weight sensing mat with the information stor­
ed in the electronic contro l unit.
The electron ic cont rol unit a lso registers the
tension on the front passenger safety belt.
The tension on the safety be lt for the front
passenger seat will be different for an adult
who is properly using the safety belt as com­
pared to the tension on the belt when it is
used to attach a child restraint to the seat.
The sensor below the latch for the safety belt
for the front seat passenger measures the
tension on the be lt . T he input from this sen­
sor is then used with the we ight to "dec ide",
whe ther there is a ch ild restraint w ith a typ ica l
1 year-o ld child on the front passenger seat
and whether or not the airbag must be turned
off .
Child restraints and Advanced Airbags
Regardless of the child restraint that you use,
make sure that it has been certified to meet
United States Federal Motor Vehicle Safety
Standards and has been certified by its manu­
facturer for use w ith an airbag . Always be sure
that the ch ild restraint is p roperly insta lled at
one of the rear seat ing pos itions . If in excep­
tional c ircu mstances you must use it on the
front passenger seat, carefu lly read all of the
info rmation on c hild safety and Advanced Air­
bags and heed a ll of the applicable WARN­
INGS. Make certain that the child restraint is
correctly recognized by the weig ht-sensing mat inside the front passenger seat, that the
front passenger airbag is turned off and that
the a irbag status is a lways correct ly signa led
by the
PAS SENGER AIR BAG OFF light.
Many types and models of child restraints
have been available over the years, new mod­
els are introduced regu larly incorporating new
and improved des igns and o lder models are
taken out of product ion. Ch ild restraints are
not standard ized . Child restraints of the same
type typically have d ifferent weights and sizes
and different 'footpr ints,' the size and shape
of the bo ttom of the ch ild restra int that sits
o n the seat, when they are inst alled on a vehi­
cle seat. These d ifferences make it v irtually
impossible to certify compliance with the re ­
quirements for advanced airbags with each
and every ch ild restraint that has ever been
sold in the past or will be sold over the course of the useful life of your veh icle.
For this reason, the United States National
Highway Traffic Safety Administrat ion has
published a list of spec ific type, makes and
models of child restraints that mus t be used
to certify comp liance of the Advanced Airbag
System i n your veh icle w ith the suppression
requirements of Federal Motor Vehicle Safety
Standard 208. These chi ld restraints are :
