Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that t he Advanced Airbag System
pe rforms in a crash. For examp le, using tire-r im
comb inat ions no t approved by Audi, lowering the
ve hicle, changing the s tiffness of the suspens ion,
includ ing the springs, suspension struts, shock
absorbers etc . can change the forces that are
measured by the airbag sensors and sent to the
e lectronic contro l unit . Some suspens ion changes
can, for example, increase the force levels meas
ured by the sensors and make the airbag system
deploy in crashes in wh ich it would not dep loy if
the changes had no t been made. Other kinds of
Airb ag sys tem
changes may red uce the force levels measured by
the sensors and prevent the airbag from deploy
i ng when it sho uld.
A WARNING
=
Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced Airbag performance a nd in
crease the risk of serious personal injury in a
crash.
- Never install suspension components that do not have the same performance charac
ter istics as the components origina lly instal
led on you r vehi cle.
- Never use tire-rim combinations that have
not been approved by Audi.
Knee airbags
Description of knee airbags
Applies to: vehicles wi th knee airbags
The knee airbag system can provide supplemen
tal protection to properly restrained front seat
occupants .

about front airbags .
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 prov ide supplemental protect ion .
The airbag system is not a substitute for your
safety belt. Rather, it is part of the overall 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 soc::>
page 135, Gener
al notes .
Remember too, airbags will deploy only once and
only in certain kinds of accidents -your safety
belts are always there to offer protect ion in those
accidents in which airbags are not supposed to
deploy or when they have already deployed, for
example when your vehicle strikes or is struck by
another after the first collis ion .
This is just one of the reasons why an airbag is
not a substitute for the safety belt. The airbag
system works most effectively when used with
the safety belts. Therefore, always wear your
safety belts correct ly.
It is important to remember that whi le the sup
p lemental knee airbag system is designed to re
duce the likelihood of serious injuries, other inju
ries, for example, swelling, bruising and minor
abras ions and friction burns can also occur when
an airbag inflates .
The knee airbag system basically consists of:
-The electronic control module
- Two inflatab le airbags (airbag and gas genera-
tor), 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 switched off
160
- in frontal collisions when the deceleration
measured by the contro l unit is too low
- in side collisions
- in rear-end collisions
- in rollovers
- in the event of a system malfunction (warning/
ind icator light is on)

.&_ WARNING
-Safety belts and the airbag system can only
provide protection when occupants are in
th e proper seating position
r:!> page 153 .
-If the airbag indicator light c::> page 17
comes when the vehicle is being used, have
the system inspected immediately by your
authorized Audi dealer.
It is possible that
the airbag will inflate when it is not sup
posed to, or will not inf late when it should.
How knee airbags work
Applies to: vehicles with knee airbags
The risk of injury to the leg area can be reduced
by fully inflated knee airbags.
Fig. 142 Inflated a irbags protect ing in a frontal coll is io n
The knee airbag system has been designed so
that the airbags for the driver and front passen
ger dep loy in certain bu t not all fronta l co llisions.
If the front airbags deploy, the knee airbags also
deploy in frontal coll isions when the deployment
threshold stored in the control unit is met.
When the system deploys, the airbags f ill with a
compressed propellant gas, and inf late between
the lower part of the instrument panel and the
driver and the lower part of the instrument panel
and the front passenger c::>

Airbag system
The side airbags installed for the front seating
positions have been designed and certified to
he lp reduce the risk of injury that can be caused
by airbags when they inflate, particularly when
the occupant sitting next to it is not seated prop
erly. The side airbag for the front passenger seat
can be used with properly installed child re
stra ints. Please be sure to read the important in
formation and warnings whenever using a child
rest raint in a veh icle: Safety belts¢
page 135,
Airbag system¢ page 143, Child safety
qpage 165.
The side airbag system basically consists of:
-the electronic control modu le and external side
impact sensors
- the two airbags located in the sides of the front
backrests
- the a irbag warning light in the instrument clus-
ter .
The airbag system is monitored electronically to make certain that it is functioning properly at all
times . Each time you switch on the ign ition, the
airbag system indicator light will come on for a
few seconds (self diagnostics) .
The s ide a irbag system supplements the safety
be lts and can help to reduce the risk of injury to
the dr iver's and front passenger's upper torso on
the s ide of the vehicle that is struck in a s ide col
lision . The airbag deploys on ly in s ide impacts
and only when the vehicle accele ration registered
by the control unit is high enough. If this rate is
be low the reference value programmed into the
control unit, the side airbags will not be trig
gered, even tho ugh the car may be badly dam
aged as a resu lt of the collision.
It is not possible
to define an airbag triggering range that w ill cov
er every poss ible angle of impact, since the cir
cumstances will vary cons iderably between one
coll is ion and a nother . Important factors include,
for example, the nature (hard or soft) of the im
pacting objec t, the ang le of impact, vehicle
speed, etc.

son why you should always wear your safety belts, not just because the law requires you to do
so
q page 135, General notes.
It is important to remember that while the sup
plemental side airbag system is designed to re
duce the likelihood of ser ious injuries, other inju
ries, for example, swelling, bru is ing, friction
burns and minor abrasions can also be assoc iated
with deployed side airbags. Remember too, side
a irbags w ill deploy only once and only in certa in
kinds of accidents -your safety belts are always
there to offer protection.
Vehicle damage, repair costs or even the lack of
vehicle damage are not necessarily an ind icat ion
of over-sens itive or fa iled airbag activation. In
some collisions, both front and side airbags may
inflat e. Remember too, that airbags wi ll deploy
on ly once and only in certain kinds of collisions -
your safety be lts are always there to offer protec
tion in those accidents in which airbags are not
supposed to deploy or when they have already
deployed .
The side airbag system will not deploy:
- when the ignition is switched off
- in side co llisions when the acceleration meas -
ured by the sensor is too low
- in front-end col lisions
- in rea r-end collisions
- in rollovers.
In some types of accidents the front airbags, side curta in airbags and side a irbags may be triggered
together .
&_ WARNING
-Safety belts and the airbag system will only
provide protection when occupants are in
the proper seating position ¢

Child safety
A WARNING
Children on the front seat of any car even with
Advanced Airbags can be seriously injured or
even killed when an airbag inflates. 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 in
flates.
- 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, or
door.
- 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
PASSEN
GER AIR BAG OFF
light does not come on
and stay on, immediately install the rear
facing child safety seat in a rear seating po
sition and have the airbag system inspected
immediately by your Audi dealer.
A WARNING
- Forward-facing child seats installed on the
front passenger seat may interfere with the deployment of the airbag and cause serious
personal injury to the child.
- If exceptional circumstances require the use
of a forward-facing child restraint on the
front passenger's seat, the child's safety and well-being require the following special
precautions to be taken:
- Always make sure that the forward-facing
seat has been designed and certified by its
manufacturer for use on a front passenger
seat with a front and side airbag.
-Always carefully follow the manufacturer's
instructions provided with the child seat
or infant carrier.
- Never install a child restraint without a
properly attached top tether strap if the
child restraint manufacturer's instructions
require the top tether strap to be used.
166
-Never put the forward-facing child re
straint up against or very near the instru
ment panel.
- Always move the front passenger seat to
the highest position in the up and down
adjustment range and move it back to the
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.
-Always make sure that the safety belt up
per anchorage is behind the child restraint
and not next to or in front of the child re
straint so that the safety belt will be prop
erly positioned.
- Always make sure that nothing prevents
the front passenger's seat from being
moved to the rearmost position in its fore
and aft adjustment range.
- Never place objects on the seat (such as a
laptop, CD player, electronic games de
vice, power inverter or seat heater for
child seats). These may influence the elec
trical capacitance measured by the capaci
tive passenger detection system and can
also fly around in an accident and cause
serious personal injury.
- Never place or use any electrical device
(such as a laptop, CD player, electronic
games device, power inverter or seat heat
er for child seats) on the front passenger
seat if the device is connected to the 12-
volt socket or the cigarette lighter socket.
-If a seat heater has been retrofitted or
otherwise added to the front passenger
seat, never install any child restraint sys
tem on this seat.
- Make sure that there are no wet objects
(such as a wet towel) and no water or oth
er liquids on the front passenger seat
cushion.
- Always make sure that the
PASSENGER
AIR BAG OFF
light comes on and stays on
all the time whenever the ignition is
switched on.
- If the
PASSENGER AIR BAG OFF light
does not come on and stay on, immediate- ly install the forward-facing child seat in a
~

rear seating position and have the airbag
system inspected by your authorized Audi
dealer.
- Always buckle the child seat firmly in
place even if a child is not sitting in it. A
loose child seat can fly around during a
sudden stop or in a collision.
- Always read and heed all WARNINGS
whenever using a child restraint in a vehi

{D) Tips
Always replace child restraints that were in
stalled in a vehicle dur ing a crash. Damage 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 "Advanced
Ai rbag System" in compliance with United States
F edera l Motor Vehicle Safety Standard ( FMVSS)
208, as well as Canada Motor Vehicle Safety
Standard (CMVSS) 208 as applicable at the time
your veh icle was manufactured.
The Advanced Airbag system in your vehicle has
been certified to meet the "low-risk" require
ments for 3- and 6-year old children on the pas
senger 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
sys tem has been certified to comply with the
"suppression" requirements of the Safety Stand
ard, to turn off the front airbag for infants up to 12 months who are restrained on the front pas
senger seat in child restraints that are listed in
the Standard.
Even though your vehicle is equipped with an Ad
vanced Airbag system, all children, especially those 12 years and younger, should always r ide
in the back seat properly restrained for their age
and size . The airbag on the passenger side makes
Child safety
the front seat a potentia lly dangerous p lace for a
child to ride. The front seat is not the safest place
for a ch ild in a forward-facing child safety seat . It
can be a very dangerous place for an infant or a
larger ch ild in a rearward-facing seat.
The vehicle's Advanced Airbag System has a ca
pacit ive passenger detection system in the front
passenger seat cushion that can detect the pres
ence of a baby or a child in a child restraint sys
tem on this seat.
The capacitive passenger detection system regis
ters the changes that result in an electrical field
when a child, a child restraint, and a baby blanket are on the front passenger seat . The change in
the measured capacitance due to the presence of
a chi ld, a child restraint, and a baby blanket on
the front passenger seat is related to the child
restraint system resting on the seat. The meas
ur ed capacitance of a child restra int system var
ies depending on the type of system and specific
make and mode l.
T he elect rical capacitance of the various types,
makes, and models of child restraints specif ied
by the U.S .National Highway Traffic Safety Ad
ministration (NHTSA) in the relevant safety
standard are stored in the Advanced Airbag Sys
tem control unit together with the capacitances
typ ical of infants and a 1-year old child. When a
child restraint is used on the front passenger
seat w it h a typical 1 year-old infant, the Ad
vanced Airbag System compares the capacitance
measured by the capacitive passenge r detection
system with the data stored in the electronic con
trol unit.
Child restraints and Advanced front airbag
system
Regardless of the ch ild restraint that you use,
make sure that it has been certified to meet Safe
ty Standards and has been cert ified by its manu
facturer for use w ith an airbag . Always be sure
that the child restraint is properly installed at
one of the rear seating positions. If in exception
al circumstances you must use it on the front
passenger seat, carefully read all of the informa-
tion on child safety and Advanced Airbags and .,.
167

Child safet y
heed a ll of the app licab le WARN INGS. Make cer
tain that the child and child restraint are correct
ly recognized by the capacitive passenger detec
tion system in the front passenger seat, that the
front passenger airbag is turned off, and that the
airbag status is always correctly signaled by the
PAS SENGER AIR BA G OFF light .
Many types and models of child restraints have
been available over the years, new models are in
troduced regularly incorporat ing new and im
proved designs and older models are taken out of
p roduct ion. Ch ild restraints are not standardized.
Ch ild rest raints of the same type typ ica lly have
d ifferent weights and s izes and d ifferen t "foot
p rints", the s ize and shape of the bottom of the
child restraint that sits on the seat, when they
are insta lled on a vehicle seat. These differences
make it virtually impossible to certify compliance
with the requirements 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 Un ited States National High
way Traffic Safety Administration has published a list of specific type, makes and models of child
restraints that must be used to cert ify compli
ance of the Advanced Airbag System in your vehi
cle with the supp ression requ irements of Federal
Motor Vehicle Safety Standa rd 208. These child
restraints are:
