Airbag system
Remember too, airbags will deploy only once and
only in certain kinds 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
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 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
ab rasions and friction burns can also occur when
an airbag inflates.
The knee airbag system basically consists of:
-The electronic control module
- 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 side collisions
- in rear-end collisions
- in rollovers
- in the event of a system malfunct ion (warning/
indicator light is on) ¢
page 17 .
_&, WARNING
-Safety belts and the airbag system can only
provide protection when occupants are in
the proper seating position¢
page 144.
-If the airbag indicator light ~ page 17
comes when the vehicle is be ing 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 will 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 .
Fig. 159 Inflated airbags protec ting in a fronta l co llis io n
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 frontal 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 fi ll with a
prope llant gas , and infla te between the lower
part of the instrument panel and the d river and
the lower part of the instrument panel and the
front passenger ¢
page 144, fig. 156.
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.
All of th is takes pla ce 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 deploy .
Fully inflated airbags in combination with proper
ly worn safety be lts s low down and limit the oc
cupant's forward movement and help to reduce
the risk of injury.

-the e lectronic contro l modu le and external side
impact sensors
- the two airbags located in the sides of the front
backrests and the two airbags * located in the
rear backrest
- the airbag warning light in the instrument cl us-
ter.
The airbag system is monitored electronically to make certa in that it is functioning properly at all
times . Each time you switch on the ignition, 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 driver 's, front and rear passenger 's upper tor
so on the side of the vehicle that is struck in a
side collision. The airbag deploys only in side im pacts and only when the vehicle acceleration reg
istered by the control unit is high enough . If this
rate is below the reference value programmed in
to the control un it, the side airbags w ill not be
tr iggered , even though the car may be bad ly
damaged as a result of the collision.
It is not pos
sible to def ine an airbag tr iggering range that
will cover every possible ang le of impact , since
the circumstances wi ll vary considerably betw een
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.¢

structions on the side airbag system.
Aside from their normal safety function, safety
belts work to help keep the driver or front pas

How side curtain airbags work
Side curtain airbags can work together with side
airbags to help reduce the risk of head and upper
torso injuries for occupants who ore properly re
strained.

c:::, fig. 163.
When the system is triggered, the s ide curtain
airbag is filled with propellant gas and breaks
through a seam above the front and rear side
windows identified by the AIRBAG label. In order
to help provide this additional protect io n, the

157

Airbag syste m
side curtain airbag must inflate within the blink
of an eye at very high speed and with great force .
The s ide curta in a irbag could injure you if your
seating position is not proper or upright or if
items are located in the area where the supp le
mental side curtain airbag inflates . This applies
especially to children
c:> page 159.
Although they are not a soft pi llow, side curtain
airbags can "cushion" the impact and in this way
they can help to reduce the risk of injury to the head and the upper part of the body .
A fine dust may develop when the airbag deploys.
This is quite normal and does not mean there is a
fire in the veh icle.
Important safety instructions on the side
curtain airbag system
Airbags are only supplemental restraints . Always
properly wear safety belts and ride in a proper
seating position.
There is a lot that you and your passengers must
know and do to help the safety be lts and airbags
do their job to provide supp lemental protect ion.
_& WARNING
Improperly wea ring safety belts and imprope r
seating pos it ions increase the ris k of serious
persona l injury and death whenever a vehicle
is being used.
- Never let occupan ts p lace any parts of their
bodies in the area from which the side cur
tain airbag inflate .
- Always make sure that the side curtain air
bags can inflate witho ut interference .
- U se the buil t- in coat hooks on ly for light
weight clothing. Never leave any heavy or
sharp-edged objects in the pockets that may
interfere w ith airbag deployment and can
cause personal injury in a collision.
- Never use hangers to hang clothes on the
hooks.
- Only use factory-installed s un shades or, if
shades installed after the veh icle leaves the
factory, use only genuine Aud i sun shades.
- Never swing the sun visors over to the side
windows if things such as pens, garage door
158
opene rs, hands-free speakers, etc. are at
tached to the sun visors. They could come
loose and cause serious injury if the side cur
tain airbag inflates.
- A deploying airbag inflates in a fract ion of a
second and with great force.
- Never attach objects to the cover or in the
deployment zone of a s ide curtain airbag.
- The airbag deployment zones must be kept
clear at all times. Make sure there are no
objects, pets, or other persons in the space
between any vehicle occupant and any air
bag at any time .
- Do not attach any accessories to the doors.
_& WARNING
-The airbag system can deploy on ly once. If
the airbag has been triggered, the system
must be rep laced by an author ized A udi
dea le r o r qualified wor ksh op.
- Always have wo rk involv ing the side curtain
airbag system, remova l and installat ion of
the airbag componen ts, or other repairs
pe rformed by a q ualified dea lership. Other
w ise the airbag system may not work cor
rectly.
- Never attempt to mod ify any componen ts of
the airbag system in any way .

Child safety
exceptional circumstances and the
PASSENGER AIR BAG OFF light does not
come on and stay on, immediately install
the rear-facing child safety seat in a rear
seating position 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.
- Never put the forward-facing child re
straint up against or very near the instru
ment panel.
-Always set the safety belt upper anchor
age to the adjustment position that per
mits proper installation in accordance
with the child restraint manufacturer's in
structions.
- 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 ad
justed to an upright position .
- 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 .
160
-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
cle

(D Tips
Always replace child restraints that were in
stalled in a vehicle during 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
Airbag 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
system has been certified to comply with the
"s uppress ion " req uirements 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.
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 restrained for their age
and size. 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
la rger 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 child restraint sys
tem on this seat .
The capacit ive 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 passenge r seat. The change in
the measured capacitance due to the presence of
a child, 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
ured capacitance of a child restraint system var-
Child safety
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 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 con
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 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 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 regularly incorporating new and im
proved designs and older models are taken out of
production. Child restra ints are no t standardized.
Child restraints 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 the seat, when they
are installed on a vehicle seat. These differences
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 ..,.
