The safety belt buckle for the driver and front
seat passenger have switches that tell the air
bag control mod ule 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 be
i ng used. Therefo re, i n a pa rtic ular collision, it
is poss ible that an airbag will not deploy at a
seating position whe re the safety belt is being
used but will inflate at the position whe re the
safety be lt is not being used .
Remembe r too, airbags will deploy only once
and on ly in ce rtain kinds of accidents -your
safety be lts are a lways there to offer pro te c
t ion in those acc idents in which airbags are
not supposed to deploy or when they have a l
ready deployed, fo r example when your vehi
cle strikes or is struck by another after the
f irst coll is ion.
This is just one o f th e reasons why an ai rbag is
not a substitute for the safety belt . The airbag
system works most effective ly when used with
the safety belts. Therefore, always wear your safety belts correctly .
It is important to remember that while the
supp lemental knee a irbag system is designed
to reduce the like lihood of serious injur ies,
other injuries, for example, swel ling, bruising,
and minor abras io ns and friction burns ca n al
so occur when an ai rbag inflates.
The knee airb ag sy stem ba sically consist s
of:
- The electronic control modu le
- Two inflatable airbags (airbag and gas gen-
erator), one for the driver 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 frontal col lisions when the dece lerat ion
measured by the control unit is too low
- in s ide collisions
- in rear-end collisions
- in ro llovers

How knee airbags work
Applies to veh icles : w ith knee airbags
The risk of injury to the l eg area can be re
duced by fully deployed knee airbags.
Fi g. 1 37 Inflated a irbags protec ting in a frontal coll i
s io n
The knee airbag system has been des igned so
that the airbags for the driver and front pas
senger deploy in certain but not all fronta l
colli sions.
If the front a irbags deploy, the knee a irbags
also deploy in frontal collisions when the de
ployment th reshold stored in the con trol unit
is met.
When the system deploys, the a irbags fill
with a propellant gas, and inflate between th e
lower part of the inst rument pa nel and the
drive r and t he lowe r part of the instr ume nt
pane l and the front p asse nger

158 Airbag sys te m
The side curtain airbags are located on both
sides of the interior above the front and rear
side windows ~
fig. 140. They are ident ified
by the word "AIRBAG" on the windshie ld
frame and the center roof pillar.
The side curtain airbag system supp lements
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 co llision . The side curtain airbag in
flates in s ide impacts and only when the veh i
cle acce lerat ion reg istered by the contro l unit
is high enoug h. If th is rate is below the refe r
ence va lue programmed into the control un it,
the side airbags will not be t riggered, even
though the ca r may be badly damaged as a re
sult of the collision . It is not possible to de
fine an a irbag tr igger 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
i nclude, for example, the natu re (hard or soft)
of the impacting object, the ang le of impact ,
ve hicl e speed, etc.~
page 159, How side cur
tain airbags work.
As ide from the ir no rmal safety function, safe
ty belts work to he lp keep the driver or front
passenger in position in the event of a co lli
sion so tha t the side curta in airbags can pro
vide protection.
The airbag system is not a subst itute for you r
safety belt. Rathe r, it is pa rt of the overall oc
cupa nt res traint system in your ve hicle. Al
ways remember that the airbag system can
only help to protect you if you are wearing
your safety be lt and wearing it properly. This
is another reason why you sho uld a lways wear
your safety belts, not just beca use the law re
qu ires you to do so
Q page 129, General
notes.
It is important to remember that while the
side curta in a irbag system is designed to help
reduce the likelihood of serious injuries, other
injuries, fo r example , swell ing, bruisi ng, and
minor abras io ns can also be associated w it h
these airbags. Remembe r too, these a irbags
will dep loy only once and only in cer tain kinds of accidents
-your safety belts are always
there to offer protection.
The side curtain airbag system basically
con sists of:
- The e lectronic control module and external
side impact sensors
- The side curtain airbags above the fron t and
rear side windows
- The a irb ag ind icator light in the inst rument
panel
T he airbag syste m is mon itored e lectronically
to make ce rtain it is functioning prope rly at all
t imes. Each t ime yo u turn on t he igni tion, the
airbag system indicator light wi ll come on for
a few seconds (self diagnostics) .
The side curtain airbag is not activated:
-if the ignition is tur ned off,
- in side collisions when the accele ration
measured by the sensor is too low,
- in rear-end col lisions,
- in rollovers.
A WARNING '"--
-Safety belts and the airbag system will
only provide protection when occupa nts
are in th e prop er seating position
Q page 53, Seats and storage.
- If the ai rbag ind icator light Q page 20
comes when the veh icle is being used,
h ave the system inspected immedia tely
by your au thori zed A udi dealer.
It is pos
sible tha t the airbag will inflate when i t
is not supposed to, or will not inflate
when it should.

162 Child Safety
-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 rearward-facing child safety
seat in a rear seating position and have
the airbag system inspected immediately
by your authorized 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
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 child re -
straints and for the different models of the .,.

172 Child Safety
-It is safer to install a forward-facing
child safety seat on the rear seat.
- Always read and heed all WARNINGS
whenever using a child restrained in ave
hicle is being used
c::;, page 161. Special
precautions apply when installing a child
safety seat on the front passenger seat
c::;, page 138, Child restraints on the front
seat -some important things to know.
A WARNING
Always take special precautions if you
must install a forward or rearward-facing
child restraint on the front passenger's
seat in exceptional situations:
- Whenever a forward or rearward-facing
child restraint is installed on the front
passenger seat, the
PASSENGER AIR
BAG OFF
light must come on and stay on
whenever the ignition is switched on.
- If the
PASSENGER AIR BAG OFF light
does not come on and stay on, perform
the checks described
c::;, page 147, Moni
toring the Advanced Airbag System.
- Take the child restraint off the front pas
senger seat and install it properly at one
of the rear seat positions if the
PASSEN
GER AIR BAG OFF
light does not stay on
whenever the ignition is switched on .
- Improper installation of child restraints
can reduce their effectiveness or even
prevent them from providing any protec
tion.
- An improperly installed child restraint
can interfere with the airbag as it de
ploys and seriously injure or even kill the
child.
- Always carefully follow the manufactur
er's instructions provided with the child
safety seat or carrier.
- Never place additional items on the seat
that can increase the total weight regis
tered by the weight-sensing mat and can
cause injury in a crash.
A WARNING
Forward-facing child restraints: -
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 .
- Never put the forward-facing child re
straint up, against or very near the in
strument panel.
- 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 forward-facing child restraint. 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.
A WARNING ~
Rearward-facing child restraints:
- A child in a rearward-facing child safety
seat installed on the front passenger
seat will be seriously injured and can be
killed if the front airbag inflates - even
with an Advanced Airbag System.
- The inflating airbag will hit the child
safety seat or infant carrier with great
force and will smash the child safety seat
and child against the backrest, center
armrest, door or roof.
- Always be especially careful if you must
install a rearward facing child safety seat
on the front passenger seat in exception
al circumstances .
- A tight tether strap on a rearward -facing
child restraint attached to the front pas
senger seat can put too much pressure
on the weight-mat in the seat and regis
ter a heavier weight in the Advanced Air
bag System. The heavier weight regis
tered can make the system work as
though an adult were on the seat and de
ploy the Advanced Airbag when it must
be suppressed causing serious or even
fatal injury to the child.
