about children and Advanced Airbags
¢ page 2 77.
E ven though yo ur vehicle is equipped with an Ad­
vanced Airbag System, make certain that all chil­
dren, especially those 12 years and younger, al­
ways ride in the back seat properly restrained for
their age and size. The airbag on the passenger
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 forward-facing child
safety seat .
It can be a very dangerous place for
a n infant or a child in a rearward-fac ing seat.
T he Advanced Airbag System in your veh icle has
been certified to comply with the requirements
of United States Federal Motor Vehicle Safety
Standa rd (FMVSS) 208, as well as Canada Motor
Veh icle Safety Standa rd (CMVSS) 208 as applica­
b le a t the time your veh icle was m an ufact ured.
Accord ing to requirements, the front Advanced
Airbag System on the passenger side has been
certified for "suppression" for infants of about 12 month old and younger and for "low risk de­
ployment" for children aged 3 to 6 years old (as
defined in the standard) .
T he
PASSENGER AIR BAG OFF ~ ; light in the
headliner tells you when the front Advanced Air­
bag on the passenger side has been turned off by
the electronic control unit.
Each time yo u turn on the ignition, the
PASSEN ­
GER AIR BAG OFF ~; ON
@ light will come on
for a few seconds and:
- PASSENGER AIR BAG OFF~; will come on if
the front passenger seat is not occupied
- PASSENGER AIR BAG OFF~; will come on if
the e lectrica l capacitance measured by the ca­
pacitive passenger detection system for the
front passenger seat equa ls the comb ined ca­
pacitance of an infant up to about one year of
age and one of the rearward-facing or forward ­
facing child restra ints listed i n Federa l Moto r
Vehicle Safety Standard ( FMVSS) 208 with

cl e was certified . Fo r a listing of the child re­
straints that were used to ce rtify you r vehicle 's

-PAS SENGER AIR BAG OFF~; will come on if
there is a small chi ld or child restraint on the
front passenger seat
- PASSENGER AIR BAG ON@ will come on if the
front passenger seat is occupied by an ad ult as
registered by the capacit ive passenger detec­
tion system
¢ page 265, Monitoring the Ad­
vanced Airbag System .
The PASSENGER AIR BAG OFF~; light comes on
when e lectrical capacitance registered on the
front passenger seat is equal to or less than the
combined capacitance of a typical 1 year-old in­
fant and one of the rearward-facing or forward ­
facing child restrai nts listed in Federal Motor Ve­
hicle Safety Standard ( FMVSS) 208 with wh ich
the Advan ced Airbag System in yo ur vehicle was
ce rtified.
If the total electr ical capacitance reg istered on
t h e front passenger seat is mo re than that of a
typ ical 1 year -old ch ild but less than the weight
of a sm all adult, the front air bag on the passen­
ger side can deploy (the
PASSENGER AIR BAG
OFF ~;
light does not come on) .
If the
PASSENGER AIR BAG OFF~; light does
not come on, the front airbag on the p assenger
s ide has not been turned off by the electronic
contro l unit and can deploy if the contro l unit
senses an impact that meets the conditions stor­
ed in its memory .
For example , the airbag may deploy if :
-a small c hild that is heav ier than a typ ica l 1
year -o ld child is on the front passenger se at
(regardless o f whethe r the child is in one o f the
child sa fe ty seats listed
¢ page 2 79), o r
- a child who has outgrown c hild rest raints is on
t he front passenge r seat .
If the front passenge r airbag is t urned off, the
PASSENGER AIR BAG OFF~; light comes on i n
t h e headliner a nd stays o n.
If the front passenger a irbag deploys, the Feder­
al Standard requi res the airbag to meet the "low
r isk " dep loymen t criteria to redu ce the r isk of in­
j u ry through interaction w it h t he airbag. "Low
risk" deployment oc curs in those crashes that
take place at lowe r decelerations as defined in

_& WARNING
To reduce the risk of injury when an airbag in­
flates, always wear safety belts properly.
- If you are unrestrained, lean ing forward, sit­
t ing s ideways or out of pos ition in anyway,
your risk of injury is much h igher.
- You will also receive serious injur ies and
could even be killed if you are up aga inst the
airbag or too close to it when it inflates -
even with an Advanced Airbag
¢page 253.

a irbags
F ig. 221 Inflated front airbags
0 0 M
-..:, ... m
Safety belts are important to help keep front
seat occupants in the p roper seated position so
that a irbags can unfold properly and provide sup­
p lemental protection in a frontal collision.
The front airbags are designed to provide addi­
tional protection for the chest a nd face of the
d river and the front seat passenger when:
- safety belts are worn properly
- the seats have been positioned so that the oc-
cupant is properly seated as far as possible
from the airbag
- and the head restraints have been properly ad-
justed
Because airbags inflate in the blink of an eye with
great force, things you have on your lap or have placed on the seat could become dangerous pro­
jectiles, and be pushed into you if the airbag in­
flates .
~ When an a irbag deploys, fine dust is released.
8 This is normal and is not caused by a fire in the
~ vehicle. Th is dust is made up mostly of a powder
co
Airb ag sys tem
used to lubricate the airbags as they deploy. It
could irritate skin.
It is important to remember that wh ile the sup­
plementa l airbag system is designed to red uce
the likelihood of serio us injuries, other injur ies,
for example swelling, bruising and minor abra­ s ions, can also happen when airbags inflate. Air­
bags do not protect the arms or the lower parts
of the body. Front airbags supplement the three­
point safety belts on ly in some frontal collisions
in which the vehicle deceleration is high e nough
to deploy the airbags .
Fron t airb ags will not depl oy:
- if the ignition is switched off when a crash oc-
curs
- in side collisions
- in rear-end collisions
- in rollovers
- when t he crash deceleration measured by the
airbag system is less than the m in imum thresh­
old needed for airbag dep loyment as registe red
by the electronic control unit
Th e front passenger airbag also will not
deplo y:
- when the front passenger seat is not occupied,
- when the e lectr ica l ca pacitance measured by
the capacitive passenger detection system for
the front passenger seat indicates that the pas­
senger s ide frontal a irbag must be switched off
by the electronic control unit (the
PASSENGER
AIR BAG OFF
11,;; light ¢ page 265 comes on
and stays on).
A WARNING
-Sitt ing in the wrong position can increase the
risk of ser ious injury in crashes.
- To reduce the risk of injury when the airbags
inflate, the drive r and passengers must al­
ways sit in an up right posit ion, must not
lea n aga ins t or place any part of their body
too close to the area where the airbags are
located.
- Occupants who are unbelted, out of posi tion
or too close to the airbag c an be serio usly
inj ured by an airbag as it unfolds with great
force in the blink of an eye¢

A WARNING
If the front airbag inflates, a ch ild without a
chi ld restraint, or in a rearward-facing child
safety seat, or in a forward-fac ing child re­
stra int that has not been properly insta lled
will be seriously injured and can be killed.
- Even though your vehicle is equipped with
an Advanced A irbag System, make certain
that all children , espec ially 12 years and
younge r, always ride on the back seat p rop­
erly rest rained for the ir age and s ize .
- Always install fo rwa rd or rear-facing child

Repair , care and disposal of the airbags
Parts of the a irbag system are installed at many
different places on your Audi. Installing, remov­ ing, servic ing or repa iring a part in an area of the
ve hicle can damage a part of an airbag system
and prevent that system from working properly
i n a collision .
There are some important things you have to
know to make sure that the effectiveness of the
system w ill not be impaired and that discarded
components do not cause injury or pollute the
env ironment.
A WARNING
Improper care, serv icing and repai r proce­
dures can increase the r is k of personal injury
and death by preventing an airbag from de­
ploying when needed or dep loying an airbag
unexpectedly:
-
- Never cover, obstruct, or change the stee r­
ing wheel horn pad or airbag cover or the in­
strument pane l or modify them in any way.
268
- Never attach any objects s uch as c upholders
or telephone mountings to the surfaces cov­
ering the a irbag un its.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one mois­
tened w ith plain water. Solvents or cleaners
could damage the airbag cover or change
the st iffness or strength of the material so
that the airbag canno t deploy and p rotect
properly.
- Never repair, adjust , or change any parts of
the airbag system.
- All work on the steering wheel, inst rument
panel, front seats or e lectr ica l system ( in­
cluding the installation of a udio eq uipment,
cellular telephones and C B radios, etc.)
m ust be perfo rmed by a qualified techn ician
who has the training and specia l equipment
necessary.
- For any work on the airbag system, we strong ly recommend that you see your au­
thorized A udi 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 install seat covers or replacement
upholstery over the front seatbacks that
have not been specifically approved by
A udi.
- Never use additional seat c ushions that
cover the areas where the side airbags in­
flate.
- Damage to the orig inal seat cove rs or to
the seam in the area of the s ide airbag
module mus t always be repaired immedi­
ate ly by an autho riz ed Au di dealer.
- The a irbag system can deploy on ly once. Af­
ter an airbag h as been deployed, i t m ust be
repla ced with new replacement parts de­
signed and approved espec ia lly for your
Audi model version . Replacement of com­
plete airbag systems or airbag components
must be perfo rmed by qua lified workshops
only. Make su re that any airbag service ac­
tion is entered in your A udi Warranty

Airbag system
In addition to their normal safety function, safe­
ty belts help keep the driver 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 overa ll occu­
pant restraint system in your vehicle. Always re­ member that the airbag system can only help to
protect you if you 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 245, Gener­
al information.
Remember too, airbags will deploy only once and
only in certain k inds 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 str ikes 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 a irbag
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
p lemental knee airbag system is designed to re­
duce the likelihood of serious injuries, other inju ­
ries, for example, swe lling, bruising and minor
abrasions and friction burns can also occur when
an airbag inflates .
The knee airbag system basically consists of:
- T he electronic control module
- T wo inflatab le airbags (airbag and gas genera-
tor), one for the driver and one for the front
passenger
- The airbag indicator ligh t in the instrument
panel
The knee airbag system will not deploy:
-whe n the ignition is switched off
- in frontal collisions when the deceleration
measured by the control un it is too low
- in side collisions
- in rear-end collisions
270
- in rollovers
-in the event of a system malfunction (warning/
ind icator light is on)
¢page 33.
A WARNING
-Safety belts and the airbag system can only
provide protection when occupants are in
the proper seating position
¢page 263.
-If the airbag indicator light¢ page 33
comes when the veh icle 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 knee airbags work
The risk of injury to the leg area con be reduced
by fully inflated knee airbags.
Fig. 224 In flated a irbags protect ing in a fro nta l coll ision
The knee airbag system has been designed so
that the airbags for the dr iver and front passen­
ger dep loy in certain but not all fronta l collisions .
If the front airbags deploy, the knee airbags also
deploy in frontal collisions when the deployment
threshold stored in the control unit is met .
When the system deploys, the airbags fill with a
prope llant 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 ¢
page 263, fig. 221 .
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.
