Airbag system
Remember too, airbags will deploy only once and
only in certain kinds 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 already deployed, for
examp le when your vehicle strikes 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 airbag
system works most effectively when used with
the safety belts. Therefore, always wear your
safety belts correctly .
It is important to remember that while the sup­
plemental knee airbag system is des igned to re ­
duce the likelihood of serious injuries, other inju­
ries, for example, swelling, bruising and minor
abrasions and friction burns can also occur when
an airbag inflates.
The knee airbag system basically consists of:
-The electronic control modu le
- Two inflatable 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
- in frontal collisions when the deceleration
measured by the control unit is too low
- in s ide collisions
- in rear-end collisions
- in rollovers
- in the event of a system malfunct ion (warning/
indicator light is on) ¢

.&, WARNING
-Safety belts and the airbag system can only
provide protection when occupants are in
the proper seating position
¢page 152.
-If the airbag indica tor lig ht ¢page 18
comes when the vehicle is being used, have
the system inspected immediate ly by your
authorized Audi dealer. It is possible that
the airbag will inf late when it is not sup­
posed to, or w ill not inflate when it should.

How knee airbags work
App lies to vehicles: wi th kne e airbags
The risk of injury to the leg area can be reduced
by fully inflated knee airbags .
Fig. 162 Inflated airbags protect ing in a frontal collis ion
The knee airbag system has been designed 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 collisions when the deployment
threshold stored in the control unit is met.
When the system deploys, the airbags fill with a
propellant gas, and inflate between the lower
part of the instrument panel and the driver and
the lowe r part of the instrument panel and the
front passenger ¢
page 152, fig. 159.
Although they are not a soft pillow, they can
"c ushion" the impact and in this way they can
help to reduce the risk of injury to the lower ex­
tremities .
A ll 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 airbags also inflate
with a great deal of force and it is important for
occupant safety that nothing should be in their
way when they dep loy .

below the refe rence value p rogrammed into the
control unit, the side curtain airbag will not be
tr iggered, even though the car may be badly
damaged as a result of the co llision. It is not pos ­
sible to define an airbag triggering range that
will cover every poss ible angle of impact, since
the circumstances will vary considerably between one co llision and another. Important factors in­
clude, for example, the nature (hard or soft) of
the impacting object, the angle of impact, vehicle speed, etc.¢
page 165, How side curtain air­
bags work.
Aside from the ir normal safety function , safety
be lts work to help keep the dr iver or front pas­
senger in posit ion in the event of a co llision so
that the side curtain a irbags can provide protec­
tion.
The airbag system is not a s ubst itute for yo ur
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 wear ing your safety be lt
and wearing it properly. Th is is another reason
why you should always wear your sa fety bel ts,
not just because the law requires you to do so
¢ page 135, General information.
It is important to remember that while the side
curta in airbag system is designed to help reduce
the likelihood of serious injuries, other injur ies,
for example , swelling , b ruising, fr iction burns
and minor abras ions can also be associated with
these airbags upon deployment . Remember too,
these airbags will deploy only once and only in
certain k inds of accidents -your safety belts are
always there to offer protectio n.
The side curtain airbag system basically
consis ts of :
- The elec tronic contro l mod ule and externa l side
impact sensors
- The side c urtain a irbags above the front and
rear side windows with ejection mitigation fea­
tures
- T he airbag indicator light in the instrument
panel
The airbag system is monitored elect ron ically to
make certa in it is function ing properly a t all
Ai rb ag sy stem
times . Each time you switch on the ign ition, the
airbag system indicator light will come on for a
few seconds (self diagnostics).
Th e s ide curtain airbag is not activated:
- if the ignition is sw itched off,
- in side co llisions when the accele ration meas-
ured by the sensor is too low,
- in rear-end col lisions .
A WARNING
-Safety belts and the airbag system will only
p rovide p rotection when oc cupan ts are in
the proper seating position ¢
page 52, Gen­
eral information.
- If the airbag ind ic a tor light~ page 18
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 will not inflate when it should.
How side curtain airbags work
Side curtain airbags con work together with side
airbags to help reduce the risk of head and upper
torso injuries for occupants who ore properly re­
strained .

Advanced front airbag system and children
Your vehicle is equipped wit h a front "Advanced
A irbag System" i n compliance w it h United States
F ederal Motor Vehicle Safe ty Standard ( FMVSS)
208 as applicable at the time your vehicle was
manufactured .
The Advanced Airbag system in your ve hicl e has
been certified to mee t the " low -risk" requ ire­
ments for 3 -and 6-year o ld children on the pas ­
senger side and small adults on the driver side.
T he low risk deployment criteria are intended to
reduce the r isk of injury through interaction with
the airbag that can occur, for example, by being
too close to the steering whee l and instrument
panel when the a irbag inflates . In add it io n, the
system has been cert ified to comply with the
"suppression" requiremen ts of the Safety Stand­
ar d, to turn off t he front airbag for infa nts up to
12 months who are restra ined on the front pas­
senger seat in child restraints that are listed i n
the Standard.
E ven though yo ur vehicle is equ ip ped with an Ad­
vanced A irbag sys tem, all children, especia lly
those 12 years and younger, should always ride in
the back seat properly restrained for their age
and size. The airbag on the passenger side makes
the front seat a potent ially dangerous p lace for
a
chi ld to r ide. The fro nt seat is not the safes t place
for a child in a forward-facing child safety seat . It
can be a very dangerous place for a n infant or a
l arger child in a rea rward-facing seat .
T he vehicle's Advanced Airbag System has a ca­
pacitive passenger detect ion system in the front
passenger seat cush ion that ca n detec t the p res­
e n ce of a baby o r a child in a c hild restra int sys­
tem on this seat.
The capacit ive passenger detection system regis ­
ters the changes that result in an electrical field
when a ch ild, a child rest raint, and a baby b la nk et
a re on the fron t passenger sea t. T he change in
the meas ured c apac it a nce due to the presence of
a child,
a chi ld restraint, and a baby blanket on
the front passenger seat is re lated to the child re­
straint system resting on the seat . The measu red
capacitance of a chi ld restraint system va ries de-

ministration (NH TSA) in the relevant safety
standard are stored in the Advanced Airbag Sys­
tem control unit together w it h the capacitances

Regardless of the c hild restra int that you use,
make sure that it has been cert ified to meet Unit­

yo u m ust use it on the front passenge r seat, care ­
fully read a ll of the information on chi ld safety
and Advanced Airbags and heed all of the appli ­
cable WARNINGS. Make certain that the child
and child restra int are correctly recogni zed by the
capacit ive passenger detection system i n the
front passenger seat, that the front passe nger
airbag is turned off, and that the a irbag status is

Child rest rain ts of the same type typ ically have
different weights and sizes and different "foot­
