The side airbag system supplements the safety
belts and can help to reduce the risk of injury to
the driver's and front passenger's upper torso on
the side of the vehicle that is struck in a side col­
lision. The
airbag deploys in side impacts and on­
ly when the vehicle acceleration registered by the
control unit is high enough. If this rate is below
the reference value programmed into the control
unit, the side airbags will not be triggered, even
though the car may be badly damaged as a result
of the collision. It is not possible to define an air­
bag
triggering range that will cover every possi­
ble
angle of impact, since the circumstances will
vary considerably
between one collision and an­
other. Important factors include, for example,
the nature (hard or soft) of the impacting object,
the angle of impact, vehicle speed, etc.
Q page 208, Important safety instructions on
the side airbag system.
Aside from their normal safety function, safety
belts work to help keep the driver or front pas­
senger in position in the event of a side collision
so that the side airbags can provide protection.
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 side airbag system can only
help
to protect you if you are wearing your safety
belt and wearing it properly. This is another rea­
son why you should always wear your safety
belts, not just because the law requires you to do
so Qpage 180, General notes.
It is important to remember that while the sup­
plemental side a irbag system is designed to re­
duce the lik eli hood of serious injuries, other inju­
ries, for
example, swelling, bruising, friction
burns and minor abrasions can also be associated
with deployed side airbags. Remember too, side
airbags will deploy only once and only in certain
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 indication
of over-sensitive or failed airbag activation. In
some collisions, both front and side airbags may
inflate .
Remember too, that airbags will deploy
only once
and only in certain kinds of collisions -
Airbag system
your safety belts 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 collisions when the acceleration meas-
ured by
the sensor is too low
-
in front-end collisions
- in rear-end collisions
-
in rollovers.
In
some types of accidents the front a irbags, side
curtain airbags and side airbags may be triggered
together.
A WARNING
--Safety belts and the airbag system will only
provide protection
when occupants are in
the proper seating position Q page 208.
-If the airbag indicator light Q page 15
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 inflate when it should.
How supplemental side airbags work
Side airbags deploy instantly and can help re­
duce the risk
of upper torso injuries for occu­
pants who are properly restrained.

passenger. In order to help provide this addition­
al protection, the side airbag must inflate within
a
fraction of a second at very high speed and with
great force . The supplemental side airbag could
injure you if
your seating position is not proper or
upright or if items are located in the area where
the supplemental side airbag expands. This ap­
plies especially to children Q page 212, Child
safety.
Supplemental side airbags inflate be­
tween the occupant and the door panel on the
side of the vehicle that is struck in certain side
collision Qfig. 162.
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 upper part
of the body.
A fine
dust may develop when the airbag deploys.
This is
normal and does not mean there is a fire
in the vehicle.
Important safety instructions on the side
airbag
system
Airbags ore only supplemental restraints. Always
properly wear safety belts and ride in a proper
seating posit ion.
There is a lot that you and your passengers must
know and act accordingly to help the safety belts
and airbags do their job to provide supplemental
protection.
A WARNING
An inflating side airbag can cause serious or
fatal injury. Improperly wearing safety belts
and improper seating positions increase the
r isk of serious personal injury and death
whenever a vehicle is being used.
-In order to reduce the risk of injury when
the supplemental side airbag inflates:
-Always sit in an upright position and never
lean against the area where the supple-
mental side airbag is located.
-Never let a child or anyone else rest their
head against the side trim panel in the
area where the supplemental side airbag
inflates.
208
-Always make sure that safety belts are
worn correctly,
-
Do not let anyone sitting in the front seat
put their hand or any other parts of their
body out of the window.
- Always
make sure that the side airbag can
inflate without interference.
- Never install seat covers or replacement
upholstery over the front seatbacks that
have not been specifically approved by
Audi.
- Never
use additional seat cushions that
cover the areas where the side airbags de­
ploy.
-
Damage to the original seat covers or to
the seam in the area of the s ide airbag
module must always be repaired immedi­
ately by an
authorized Audi dealer.
-Objects between you and the airbag can in­
crease the risk of injury in an accident by in­
terfering with the way the airbag unfolds or
by being pushed into you as the airbag in­
flates.
-Never place or attach accessories or other
objects (such as cup holders, telephone
brackets, or even large, bulky objects) on
the doors, over or near the area marked
"AIRBAG" on the seat backrests.
-Such objects and accessories can become
dangerous projectiles and cause injury
when the supplemental side airbag de­
ploys.
- Never carry any
objects or pets in the de­
ployment space between them and the
airbags or allow children or other passen­
gers to travel in this position.
- Always
use the built-in coat hooks only for
lightweight clothing. Never leave any heavy
or sharp-edged objects in the pockets that
may interfere with side airbag deployment
and can cause personal injury in an accident.
- Always
prevent the side airbags from being
damaged by heavy objects knocking against
or hitting the sides of the seatbacks.
-The airbag system can only be triggered
once. If the airbag has been triggered, the
system must be replaced by an authorized
Audi dealership. ~

-Damage (cracks, deep scratches etc.) to the
original seat covers or to the seam in the
area of the side airbag module must always
be repaired immediately by an authorized
Audi dealer.
-If children are seated improperly, their risk
of injury increases in the case of an accident
¢page 212, Child safety.
-Never attempt to modify any components of
the airbag system in any way.
-
In a side collision, side airbags will not func­
tion properly if sensors cannot correctly
measure increasing air pressure inside the
doors when air escapes through larger, un­
closed openings in the door panel.
-Never drive with interior door trim panels
removed.
-Never drive when parts have been re­
moved from the inside door panel and the
openings they leave have not been proper­
ly closed.
- Never drive
when loudspeakers in the
doors have been removed unless the
speaker holes have been properly closed.
- Always
make certain that openings are
covered or filled if additional speakers or
other equipment is installed in the inside
door panels.
-Always have work on the doors done by an
authorized Audi dealer or qualified work­
shop.
Airbag system
Side curtain airbags
Description of side curtain airbags
The side curtain airbag system can provide sup­
plemental protection to properly restrained oc­
cupants.
Fig. 163 Side curtain airbags, driver's side: side curtain air­
bag locat ion
The side curtain airbags are located on both sides
of the interior above the front and rear side win­
dows~ fig. 163. They are identified by the word
"AIRBAG" on the windshield frame and the cen­
ter roof pillar .
The
side curtain airbags contain features that
provide ejection mitigation to help prevent vehi­
cle occupants or parts of their bodies from being
completely or partially ejected from the vehicle
interior in certain side impacts and vehicle roll­
overs.
The
side curtain airbag system supplements the
safety belts and can help to reduce the risk of in­
jury for occupants' heads and upper torso. The
side
curtain airbag inflates in side impacts and
only when the vehicle acceleration registered by
the control unit is high enough. If this rate is be­
low the reference value programmed into the
control unit, the side curtain airbag will not be
triggered, even though the car may be badly
damaged as a resu lt of the collision. It is not pos­
sible to define an airbag triggering range that
will cover every possible angle of impact, since
the circumstances will vary considerably between
one collis ion 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 210, How side curtain air­
bags work .

and minor abrasions can also be associated with
these airbags upon deployment. Remember too,
these airbags will deploy only once and only in
certain kinds of accidents -your safety belts are
always there to offer protection.
The side curta in airbag sy stem basically
consists
of:
-The electronic control module and external side
impact sensors
-The side curtain airbags above the front and
rear side windows with ejection mitigation fea­
tures
-The airbag indicator light in the instrument
panel
The airbag system is monitored electronically to
make certain it is function ing properly at all
times. Each time you switch on the ignition, the
airbag system indicator light will come on for a
few seconds (self diag nasties).
The side curtain airbag is not activated:
-if the ignition is switched off,
-
in side collisions when the acceleration meas-
ured by the sensor is too low,
- in
rear-end collisions .

A WARNING
-Safety belts and the airbag system will only
provide
protection when occupants are in
the proper seating position Q page 44,
Seats and storage.
-If the airbag indicator light Q page 15
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 inflate when it should.
How side curtain airbags work
Side curtain airbags can work together with side
airbags to help reduce
the risk of head and upper
t orso injuries for occupants who are properly re­
strained.
Fig. 164 Illustration of principle: Inflated side curtain air­
bags on
the left side
The side curtain airbags inflate between the oc­
cupant and the windows on the side of the vehi­
cle
that is struck in a side collision Q fig. 164.
When the system is triggered, the s ide curtai n
airbag
is filled with propellant gas and breaks
th rough a seam above the front and rear side
windows identified by the AIRBAG label. In order
to help provide this additional protection, the
side curtain airbag must inflate within the blink
of an eye at very high speed and with great force .
The
side curtain airbag could injure you if your
seating position is not proper or upright or if
items are located in the area where the supple­
mental side curtain airbag inflates. This applies
especially to children Qpage 212.
Although they are not a soft pillow, side curtain
airbags can "cushion" the impact and in this way .,..

fire
in the vehicle.
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 lo t that you and your passengers must
know and do to help the safety belts and airbags
do their job to provide supplemental protection.
A WARNING
Improperly wearing safety belts and improper
seating positions increase the risk of serious
personal injury and death whenever a vehicle
is being
used.
-Never let occupants place 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 without interference.
-Use the built-in coat hooks only for light­
weight clothing . Never leave any heavy or
sharp-edged objects in the pockets that may
interfere with airbag deployment and can
cause personal injury in a collision.
-Never use hangers to hang clothes on the
hooks.
- Only use factory-installed sun shades or, if
shades installed after the vehicle leaves the
factory, use only genuine Audi sun shades.
-Never swing the sun visors over to the side
windows if things such as pens, garage door
openers, 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 fraction of a
second and with great force.
-Never attach objects to the cover or in the
deployment zone of a side curtain airbag.
Airbag system
-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.
A WARNING
~
-The airbag system can deploy only once. If
the airbag has been triggered, the system
must be replaced by an authorized Audi
dealer or qualified workshop.
-Always have work involving the side curtain
airbag
system, removal and installation of
the airbag components, or other repairs
performed by a qualified dealership. Other­
wise the airbag system may not work cor­
rectly.
-Never attempt to modify any components of
the airbag system in any way.

Important information
Introduction
The rear seat is generally the safest place in a
collision .
The physical principles of what happens when
your vehicle is in a crash apply also to children
¢page 182, What happens to occupants not
wearing safety belts? . But unlike adults and
teenagers, their muscles and bones are not fully
developed. In many respects children are at
greater risk of serious injury in crashes than
adults.
Because children's
bodies are not fully devel­
oped, they require restraint systems especially
designed for their size, weight, and body struc­
ture. Many countries and all states of the United
States and provinces of Canada have laws requir­
ing
the use of approved child restraint systems
for infants and small children .
In a frontal crash at a speed of 20-35 mph
(30-56 km/h) the forces acting on a 13 lbs (6 kg)
infant will be more than 20 times the weight of
the child. This means the weight of the child
would
suddenly be more than 260 lbs (120 kg).
Under these conditions, only an appropriate child
restraint properly used can reduce the risk of se­
rious injury .
Child restraints, like adult safety
belts, must be used properly to be effective .
Used improperly, they can increase the risk of se­
rious injury in an accident.
Consult the child safety seat manufacturer's in­
structions in order to be sure the seat is right for
your child's size¢ page 215, Important safety
instructions for using child safety seats. Please
be sure to read and heed all of the important in­
formation and WARNINGS about child safety,
Advanced Airbags, and the installation of child
restraints in this chapter.
There is a lot you need to know about the Ad­
vanced Airbags in your vehicle
and how they work
when infants and children in child restraints are
on the front passenger seat. Because of the large
amount of important information, we cannot re-
212
peat it all here. We urge you to read the detailed
information in this owner's manual about airbags
and the Advanced Airbag System in your vehicle
and the very important information about trans­
porting children on the front passenger seat.
Please be sure to heed the WARNINGS -they are
extremely important for your safety and the safe­
ty of your passengers, especially infants and
small children.
.&_WARNING
-Accident statistics have shown that children
are generally safer in the rear seat area than
in the front seating position. Always restrain
any child age 12 and under in the rear.
-
All vehicle occupants and especially children
must be restrained properly whenever riding
in a vehicle.
An unrestrained or improperly
restrained child could be injured by striking
the interior or by being ejected from the ve­
hicle
during a sudden maneuver or impact.
An unrestrained or improperly restrained
child is also at greater risk of injury or death
through contact with an inflating airbag.
-A suitable child restraint properly installed
and used at one of the rear seating positions
provides the highest degree of protection
for infants and small children in most acci­
dent situations.
.&_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.

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 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.
- 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
Child safety
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
a ll
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.

(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
Federal Motor Vehicle Safety Standard (FMVSS) ~
213

Downloaded from www.Manualslib.com manuals search engine Child safety
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" 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
"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 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 ride. 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
larger child in a rearward-facing seat.
The vehicle's Advanced Airbag System has a ca­
pacitive
passenger detection system in the front
passenger seat cushion that can detect the pres­
ence of a baby or a child in a ch ild restraint sys­
tem on this seat.
The capacitiv e passenger detection system regis ­
ters the changes that resul t in an electrical field
when a ch ild , 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 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
ies
depending on the type of system and specific
make and model.
The electrical capacitance of the various types,
makes, and models of child restraints specified
by
the U.S.National Highway Traffic Safety Ad-
214
ministration (NHTSA) in the relevant safety
standard are stored in the Advanced Airbag Sys­
tem control unit together with the capacitances
typical of infants and a 1-year old child. When a
child
restraint is used on the front passenger
seat with a typical 1 year-old infant, the Ad­
vanced Airbag
System compares the capacitance
measured by the capacitive passenger detection
system with the data stored in the electronic con­
trol unit.
Child restraints and Advanced front airbag
system
Regardless of the child restraint that you use,
make sure that it has been certified to meet Unit­
ed States Federal Motor Vehicle Safety Standards
and ha s been certified by its manufacture r for
use with a n airbag. Always be sur e that the child
restraint is properly installed at one of the rear
seating positions. If in exceptional circumstances
you must use it on the front passenger seat, care­
fully
read all of the information on child safety
and Advanced Airbags and heed all of the appli­
cable WARNINGS. Make certain that the child
and child restraint are correctly recognized by the
capacitive passenger detection system in the
front passenger seat, that the front passenger
airbag is turned off, and that the airbag status is
always correctly si
gnaled by the PASSENGER AI R
BAG OFF light.
Many types and models of child restraints have
been available over the years, new models are in­
troduced regularly incorporating new and im­
proved
designs a nd older models are taken out of
production. Child restraints are not standardized .
Child
restraints of the same type typically have
different weights and sizes and different "foot­
pr ints", the size and shape of the bottom of the
child restraint that sits on the seat, when they
are installed on a vehicle seat. These differences
make it virtually impossible to certify compliance
with the requirements for advanced airbags with
each
and every child restraint that has ever been
sold in the past or will be sold over the course of
the useful life of your vehicle.
For
this reason, the United States Nat ional High­
way Traffic
Safety Administration has published a ..,_
