Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced A irbag System
pe rforms in a crash. For e xamp le, using t ire -r im
comb inations no t approved by Audi, lowering t he
veh icle, chang ing the stiffness o f the suspe nsio n,
i n cluding the springs, suspension struts, shock
absorbers etc . can change the forces that are
measured by the airbag sensors and sent to the
electronic 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 c rashes in w hich it would not deploy if
the changes had not been made. Other ki nds of
200
changes may reduce the force levels measured by
the sensors and prevent the airbag from deploy
i ng when it should .
_& WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim comb inations can
change Advanced Airbag performance and in
crease the r isk 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 your vehicle.
- Never use tire-r im combinations that have
not been approved by Aud i.
Knee airbags
Description of knee airbags
Applies to vehicles: with knee airbags
The knee airbag system can provide supplemen
tal protection to properly restrained front seat
occupants .

threshold stored in the control unit is met
¢ page 194, More important things to know
about front airbags .
In addition to their normal safety function, safe
ty belts help keep the driver or front passenger in
posit ion in a frontal collision so that the airbags
can prov ide supplemental protection.
The airbag system is not a subst itute 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 wear ing it properly . This is why you should
always wear your safety belt, not just because
the law requires you to do so ¢
page 176, Gener
al notes .
Remember too, airbags will deploy only once and
only in certain k inds of accidents -your safety
be lts are always there to offer protection in those
accidents in which airbags are not supposed to
deploy or when they have a lready deployed, for
example when yo ur vehicle str ikes or is str uck by
anothe r after t he f irst collision .
This is just one of the reasons why an airbag is
n ot a substi tute for the safety belt. The airbag
system works most effectively when used with
the safety belts . Therefore , a lways wear your
safety be lts correct ly .
It is important to remember that while the sup
p lemen tal knee a irb ag sys tem is designed to re
duce the like lihood of serious injur ies, other inju
ries, for example, swelling, bruising and minor
abrasions and friction burns can also occur when
an airbag inf lates.
The kn ee airbag sy stem basically con sist s of :
- T he elec tronic contro l module
- Two inflatab le airbags (airbag and gas genera -
tor), one for the drive r and one fo r the front
passenge r
- The airbag indicator light in the instrument
panel
The knee airbag s ystem will not deploy:
- when the ign ition is switched off
Airb ag sys tem
-in frontal co llisions when the deceleration
measured by the control unit is too low
- in side co llisions
- in rear-end collisions
- in rollovers
- in the event of a system malfunction (warn ing/
ind icator light is on)
¢ page 21.
.&, WARNING
- Safety belts and the airbag system can only
provide protect io n when occupants are i n
the proper seat ing position ¢
page 194.
- If the a irbag ind icator light¢ page 21
comes when the veh icle is being used, have
the system inspected immediately by your
authorized Audi dealer. It is possib le that
the airbag will inflate when it is not sup posed to, or w ill not inflate when it should.
How knee airbags work
Applies to vehicles: wit h knee airbags
The risk of injury to the leg area can be reduced
by fully inflated knee airbags.
Fi g. 168 Inflated a irbags protect ing in a frontal coll is ion
The knee airbag system has been des igned so
that the airbags for the driver and front passen
ger dep loy in certain but not all fronta l co llisions .
If the front airbags deploy, the knee airbags also
deploy in frontal coll is io ns when the deployment
threshold stored in the cont rol un it is met .
When the system deploys, the airbags fill with a compressed propellant 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

Airbag syste m
Although they are not a soft pillow, they can
"cushion" the impact and in this way they can
he lp to reduce the risk of injury to the lower ex
tremities .
All of this takes place in the blink of an eye, so
fast that many people don't even realize that the airbags have deployed. The a irbags also inflate
with a great deal of force and it is important for
occupant safety that nothing should be in their
way when they deploy .
Fully inflated airbags in comb ination with proper
ly worn safety belts slow down and limit the oc
cupant's forward movement and help to reduce
the risk of inju ry.
Important safety instructions on the knee
airbag system
App lies to veh icles : with knee a irbags
Airbags are only supplemental restraints . Always
wear safety belts correctly and ride in a proper
seating position.
There is a lot that you and your passengers must
know and do to help the safety belts and airbags
to provide supplemental protection .
,&. WARNING
An inflating knee airbag can cause ser ious in
jury. Wearing safety bel ts incorrectly and im
proper seating positions increase the r isk of
serious personal injury and death whenever a
vehicle is being used.
- The knee airbag system cannot protect you properly if you are seated too close to any of
the airbag locat ions. When adjusting their
seat positions, it is important that both the driver and the front passenger keep their
upper bodies and knees at the following
min imum safe distances:
- at least 10 inches (25 cm) between the
chest and the steering wheel/instrument panel.
- at least 4 inches (10 cm) between the
knees and the lower part of the instru ment panel.
- The risk of persona l injury increases if you
lean forward or to the s ide, or if the seat is
202
improperly positioned and you are not wear
ing your safety belt. The risk increases even
more should the airbag deploy.
- Always make sure that the knee a irbag can
inflate w ithout interference. Objects be
tween you and the airbag can increase the
r isk of injury in an accident by interfering
w ith the way the airbag deploys or by being
pushed i nto you as the a irbag deploys.
- Never let anybody, especia lly children or
anima ls ride in the footwell in front of the
passenger seat. If the airbag deploys, this
can result in serious or fatal injuries .
- Never carry objects of any kind in the foot
well area in front of the driver's or pas senger's seat. Bulky objects (shopp ing
bags, for example) can interfere with or
prevent proper dep loyment of the a irbag.
Small objects can be thrown through the
vehicle if the airbag deploys and injure you
or your passengers.
- Ma ke sure there are no crac ks, deep scratch
es o r other damage in the area of the i nst ru
ment panel where the knee airbags are lo
cated .
- If children are incorrec tly seated, their risk
of injury increases in a coll is ion

Airbag syste m
interior in certain side impacts and vehicle
rollovers.
The s ide curta in a irbag system supplements the
safety belts and can he lp to reduce the r is k of in
jury for occupants' heads and upper torso on the
side of the vehicle that is struck in a side co lli
sion. The side curtain airbag inflates in side im
pacts and on ly when the vehicle acceleration reg
istered by the control unit is h igh enough . If this
rate is below the reference value programmed in
to the control un it, the side curta in a irbag w ill
not be triggered, even though the car may be
badly damaged as a result of the collision.
It is
not possib le to define an airbag trigger ing range
that will cover every poss ible angle of impact,
since the circumstances will vary considerab ly be
tween one collision and another . Important fac
tors incl ude, for example, the nature (hard or
soft) of the impacting object, the ang le of im
pact, vehicle speed, etc .
q page 207, How side
curtain airbags work .
Aside from their normal safety function, safety
be lts work to help keep the driver or front pas

that the side curtain airbags can provide protec
tion .
The airbag system is not a substitute for your safety belt. Rather, it is part of the overall occu

It is important to remember that whi le the s ide
curtai n airbag system is des igned to he lp red uce
the likelihood of serious injuries, other injuries,
for example, swe lling, b ruising, friction burns
and minor abrasions can also be assoc iated with
these airbags upon deployment . Remember too,
these airbags will deploy only once and only in
certa in kinds of acc idents -your safety be lts are
always there to offer protection .

The side curtain airbag system basically
consists of :
-The e lectronic cont ro l mod ule and externa l side
impact sensors
- The side curtain airbags above the front and
rear side windows with ejection mitigat ion fea
tures
- The ai rbag indicator light in the instrument
panel
The airbag system is mon itored e lectron ica lly to
make certain it is functioning properly at all
times. Each t ime you switch on the ignition, the
airbag system ind icator light will come on for a
few seconds (se lf diagnostics) .
The side curtain airbag is not activated:
-if the ignition is switched off,
- in side collisions whe n the accele ration meas -
ured by the sensor is too low,
- in rea r-end co llisions .

Your vehicle is equipped with a front "Advanced
Airbag System" in compliance w ith 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
system has been certified to comply with the
"s uppress ion " req uirements of the Safety Stand
a rd, to turn off the front ai rbag for infants up to
12 months who are restrained on the front pas
senger seat in child restraints that are listed in
the Standard.
E ven though your vehicle is equipped with an Ad ·
vanced Airbag system, all children, especially
those 12 years and younger, should always ride
in the back seat properly restra ined for their age
and si ze. The airbag on the passenger side makes
the front seat a potentially dangerous place for a
child to r ide . 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 an infant or a
l arger child in a rearward -facing seat.
The vehicle's Advanced A irbag System has a ca
pac itive passenger detect io n system in the front
passenger seat cush ion that can detect the pres
ence of a baby or a child in a ch ild restraint sys
tem on this seat .
The capacit ive passenger detection system regis
ters the changes that result in an electrical fie ld
when a ch ild, a child restra int, and a baby blanket
are on the front passenge r seat. The change in
the measured capacitance due to the presence of
a child, a child restraint, and a baby b lanket on
the front passenger seat is related to the child restraint system resting on the seat. The meas
ured capacitance of a child restraint system var-
Ch ild safety
ies depending on the type of system and specific
make and mode l.
T he elect rical capac itance of the va rious types,
makes, and models of chi ld restra ints specified
by the U.S .National Highway Traff ic 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 co n
t rol 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 c hild rest raint is p roperly installed at
one of the rear seating positions . If in exception
al circumstances you must use it on the front
passenge r seat, carefu lly read a ll of the informa
tion on child safety and Advanced Airbags and heed all of the applicable WARNINGS . Make cer
tain that the chi ld and child restraint are correct
ly recognized by the capac itive passenger detec
t ion system in the front passenger seat, that the
front passenger a irbag is turned off, and that the
airbag status is always correctly s ignaled by the
PASSENGER AIR BAG OFF light .
Many types and models of child restra ints have
been available over the years, new models are in
troduced regu larly incorporating new and im
proved designs and older models a re take n out of
production. Child restra ints are no t standa rdized.
Child res tra ints of the same type typically have
different weights and sizes and different "foot
prints", the size and shape of the bottom of the
chi ld restraint that sits on th e seat, when they
are installed on a vehicle seat. These d ifferences
make it virtually impossib le to certify compliance
with the requirements for advanced a irbags w ith
each and every child restra int that has ever been ..,.
