Audi dealer is familiar with these require­
ments and we recommend 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
change the way that the Advanced Airbag Sys­
tem performs in a crash. For example, using
tire-rim combinations not approved by Audi,
lowering the vehicle, changing the stiffness of
the suspension, including the springs, suspen­
sion struts, shock absorbers etc. can change
the forces that are measured by the airbag
sensors and sent to the electronic control
unit. Some suspension changes can, for exam­ ple, increase the force levels measured by the
sensors and make the airbag system deploy in
crashes in which it would not deploy if the
changes had not been made. Other kinds of
changes may reduce the force levels meas­
ured 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 seat 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 information about
safety belt use to the electronic control unit.
A WARNING
Changing the vehicle's suspension includ­
ing use of unapproved tire-rim combina­
tions can change Advanced Airbag per-
Airbag system 167
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 origi­nally installed on your vehicle.
- Never use tire-rim combinations that have not been approved by Audi.
A 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 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.
Knee airbags
Description of knee airbags
The knee airbag system can provide supple­
mental protection to properly restrained
front seat occupants.
Fig . 169 Driver 's knee airbag
The driver knee airbag is in the instrument
panel underneath the steering wheel
¢ fig . 169, the airbag for the passenger is at
about the same height in the instrument pan­
el underneath the glove compartment.
The knee airbag offers additional protection
to the driver 's and passenger's knees and up­
per and lower thigh areas and supplements
the protection provided by the safety belts.
Ill-

168 Airbag sys tem
If 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 161, 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 w hy you shou ld always wear your safety
be lt, not just because the law requires yo u to
do soc:>
page 144, 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
ready deployed, fo r example whe n your veh i­
cle st rikes 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 belts. Therefore, always wear your
safety be lts correctly.
It is impor tan t to remember that whi le the
supp lemental knee a irb ag sys tem is designed
to reduce the like lihood of serious injur ies, othe
r injur ies, for example, swelling, bru is ing
and minor abrasions and friction b urns can a l­
so occur when an airbag inflates .
The knee airbag system basically consists
of:
-The e lectronic control module
- Two in flatable a irbags (a irbag an d gas gen-
erator), one for the driver and o ne for the
front passenger
- The a irbag indicator light in the instr ument
pane l
The knee airbag system will not deploy:
-when t he ignit ion is switched off
- in frontal collisions when the deceleration
measured by the control un it is too low
- in side co llisions
- in rear-end collisions
- in rollovers
- in the event of a system malfunction (war n-
ing/ind icator light is on)

A WARNING
-
-Safety belts and the airbag system can
only provide protection when occupants
are in the proper seating position
<:>page 161.
-If the airbag ind icator light <:> page 18
comes when the ve hicle is being used,

and minor abrasions can also be associated
with deployed side airbags. Remember too,
side airbags will deploy only once and on ly in
certain k inds of accidents -your safety belts
are always there to offer protect ion.
Vehicle damage, repair costs or even the lack
of vehicle damage are not necessar ily an indi ­
cation of over-sensitive or failed airbag activa­
tion . In some collisions, both front and s ide
a irbags may inf late . Remember too, that air ­
bags will deploy only once and only in certain
kinds of collisions -your safety belts are al­
ways there to offer protect ion in those acci­
dents in wh ic h airbags are not supposed to
deploy or w hen they have already deployed .
The side airbag system will not depl oy :
- when the ignition is switched off
- in s ide collisions when the acceleration
measured by the sensor is too low
- in front-end collisions
- in rear-end collisions
- in ro llovers.
I n some types of a ccidents the front a irbags,
side curta in a irbags and side airbags may be
triggered together.
A WARNING
- Safety belts and the airbag system will
only provide protection when occupants
are in the proper seating posit ion

How supplemental side airbags work
Side airbags deploy instantly and can help re­
duce the risk of upper torso injuries for occu­
pants who are properly restrained.
Fig . 1 72 Inflated side a irbags on left side of vehicle ,
rear side airbag
When the system is triggered, the a irbag is
filled with propellant gas and breaks through
a seam in the seat surface area ma rked ''AIR­
BAG".
It expands between the side trim panel
and the passenger. In orde r to help provide
th is add it ional protect ion, the side airbag
must inflate within a fraction o f a second at
very high speed and with great force. The sup­
plementa l side airbag could injure you if your
seat ing position is not proper or upright or if
items are located in the area where the sup­
plementa l side airbag expands . This applies
especially to child ren

Side curtain airbags
Description of side curtain airbags
The side curtain airbag system can provide
supplemental protection to properly restrain ­
ed occupants.
Fi g. 173 Side curtai n airbags, dr iver 's s ide: side curtai n
ai rbag locat ion
The side curtain airbags are located on both
sides of the interior above the front and rear
side windows ¢
fig. 173. They are ident ified
by the word "AIRBAG" on the windshie ld
frame and the center roof p illar.
The side curtain airbag system supp lements
the safety belts and can help to reduce the risk of injury for occupa nts' heads and upper
torso on the side of the veh icle tha t is struc k
Airba g system 173
in a side co llision . The side cu rtain airbag in­
flates in side impacts and only when the vehi­
cle acceleration registered by the contro l un it
is h igh eno ugh. 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
su lt of the co llision . It is not possib le to de­
fine an airbag triggering range that will cover every possib le ang le of impa ct, sin ce the cir­
c u mstances will vary cons iderably be tween
one collision and anothe r. Important factors
incl ude, fo r example, the nature (hard or soft)
of the impacting object, the ang le of impact,
vehicle speed, etc . ¢
page 17 4, How side cur­
tain airbags work.
Aside from their normal safety f unction, safe­
ty belts work to help keep the driver or front passenger in position in the event of a coll i­
s ion so that the side curtain airbags can pro­
vide protection .
The airbag system is not a substit ute for your
safety belt. Rather, it is part of the overall oc­ cupant restra int system in your vehicle. Al­
ways remember that the a irbag system can
o nly help to protec t you if you are wear ing
you r safety be lt and wea ring it p roperly. This
i s a nothe r reason why you should a lways wear
yo ur safe ty be lts, no t ju st because the law re­
quires you to do so ¢

It is impo rtant to remembe r that w hile the
s id e cu rtain air bag system is desig ned to help
reduce t he likelihood of serious injuries, other
injur ies, for examp le, swelling, br uising, and
minor ab rasions can also be associated with
these a irbags upon deployment. Remember
too, these airbags will deploy only once and
o nly in certain kinds of acc idents -your safety
belts are always the re to offer protection .

Important safety instructions on the
side curtain airbag system
Airbags are only supplemental restraints . Al·
ways properly wear safety belts and rid e in a
proper seating position .
The re is a lot that you and your passengers
must know and do to he lp the safety belts and
airbags do th eir job to provide supp lemental
protection .
A WARNING
-Improperly wearing safety belts and im-
p roper seating posit ions increase the risk
of ser ious personal inju ry and death when·
ever a vehicle is being used.
- Never let occupants place any parts of
their bod ies in the area from which the
side curta in a irbags inflate.
- Always make sure that the s ide curtain

-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 a front "Ad­
vanced Airbag System" in compliance with United States Federal Motor Vehicle Safety
Child Safety 177
Standard (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 ..,.

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
restra int 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 ch ild, the Advanced Airbag Sys­
tem compares the we ight measured by the
weight sensing mat with the in formation stor­
ed in the electronic control unit.
The ele ctron ic cont rol unit also registers the
tension on the front passenge r safety belt.
The tension on the safety be lt fo r the front
passenger seat will be different for an ad ult
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 measu res the
tension on the be lt. The input from this sen­
sor is then used with the we ight to "decide",
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 a nd has been certified by its manu­
facture r fo r u se w ith an airbag. Always be s ure
that t he ch ild res traint is p rope rly insta lled at
one o f th e rear seat ing pos itions. If in excep­
tional c ircu mstances you must use it on the
front passenger seat, caref ully read all of the
info rmation on c hild safety and Advanced Air­
bags and heed all 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 stat us is always cor rect ly signa led
by the
PASSENGER AIR BAG OFF light.
Many types and models of child res traints
have been available over the years, new mod­
els are introduced regu larly incorporating new
and improved des igns and older 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 diff erent 'footpr ints,' the s ize and shape
of the bo ttom of the ch ild restra int that sits
o n t he seat, when they a re inst alled on a vehi­
cle sea t. Th ese d ifferences make it vir tually
impossible to certify compliance with the re ­
quirements for advanced airbags with eac h
and every child restra int that has ever been
sold in the past or will be sold over the course
of the useful life of your veh icle.
For th is reason, the United States National
Highway Traffic Safety Adm inistrat ion has
published a list of specific type, makes and
models of child restraints that must 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
Standa rd 208. These chi ld restraints are:

@ Tips
The child seats listed in categories A to C have been statically tested by A udi on ly for
the Advanced A irbag function.
Important safety instructions for using
child safety seats
Correct use of child safety seats substantially
reduces the risk of injury in an accident!
As the dr iver, you are responsib le for the safe­
ty of everybody in the veh icle, especially ch il­
dren:
... Always use the r ight chi ld safety seat for
each child and always use it properly
¢page 182.
... Always carefully fo llow the child safety seat
manufactu rer's inst ruct io ns on how to route
th e safety belt properly through the child
safety sea t .
... When usi ng the vehicle safe ty belt to install
a child safety se at, you m ust first activate
t he conve rtible locking retractor on the
safety belt to prevent the child safety seat
from mov ing
¢ page 186.
... Push the ch ild safety seat down with your
full weight to get the safety be lt really tight
so that the seat cannot move forward or
sideways more than one inch (2 .5 cm) .
... If a strap o r tethe r is be ing used to tie the
child safety seat to the front passenger
seat , make sure tha t it is not so tigh t that it
causes the weigh t-sens ing ma t to measure
more weight than is act ually on the seat.
... Sec ure unused safety belts on the rear seat
¢ page 181.
Always remember: Even tho ugh yo ur vehicle is
equipped with an Advanced Airbag system, all
c h ildren, especially those 12 years and young ­
er, shou ld always r ide in the back seat proper-
ly restrained for the ir age and size. ..,. •
