q page 132, How side
curtain airbags work.
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 collision so
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 overa ll 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 another reason
why you should always wear your safety belts, not just because the law requires you to do so
q page 106, General information.
It is important to remember that while the side
curtain airbag system is des igned to help reduce
the likelihood of serious injuries, other injuries,
for example, swe lling, bruising, and m inor abra­
sions can also be associated with these airbags.
Remember too, these airbags will dep loy o nly
once and only in certain kinds of accidents -your
safety belts are always there to offer protection .
The side curtain airbag system 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 monito red electronically to
make certa in it is fun ction ing properly at all
times. Each time you turn on the ignition, the air­
bag system indicator light will come on for a few
seconds (self diagnostics) .
The side curtain airbag is not activated:
-if the ignit ion is tu rned off,
- in s ide collisions when the accelerat io n meas-
ur ed by the sensor is too low,
- in rear-end collisions.
132
A WARNING
-Safety belts and the airbag system will only
provide protect ion when occupants are in
the proper seating position
~ page 42,
Front seats .
-If the airbag ind icator light q page 14
comes when the veh icle 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
torso injuries for occupants who are properly re­
strained.
Fig. 119 Il lustratio n of pr inciple: I nflated s ide curta in air ­
bags on t he le ft s ide
The side curtain airbags inflate between the oc­
cupant and the w indows on the side of the veh i­
cle that is struck in a side collision
~ fig. 119.
When the system is triggered, the side curta in
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 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
seat ing position is not prope r or upright or if
i tems a re located in the area where the supple­
mental sid e cu rtain airbag inflates. This applies
especially to children ~

airbags can "cush ion" 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 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 lot 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 airbags inflate.
-Always make sure that the side curtain air­ bags can inflate without interference. Un­
suitable accessories fitted inside the expan­
sion range of a head airbag can dangerously
interfere with its function. A deploying head
airbag develops enough force to catapult
any piece of add-on component out of its
path of inflation and into the passenger
compartment. An occupant hit by such a
projectile can suffer serious injury or death
<=> page 215, Technical Modifications.
- Do not swivel the sun visors to the side if
you have any objects clipped onto them (for
example pens) . If the airbag should deploy,
you could be injured by these objects.
- 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 an accident.
- Never use hangers to hang clothing from
the hooks.
Airbag system
-Only use factory-installed sun shades or, in
the case of shades installed after the vehicle
leaves the factory, only Audi roll-up
sunscreens may be used
<=> page 214, Addi­
tional accessories and parts replacement.
- Always sit in proper seating position and
wear safety belts while traveling so that the
side curtain airbags can help provide protec­
tion .
- The airbag system can only be triggered
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 an authorized Audi dealer or
qualified workshop. Otherwise the airbag
system may not work correctly.
- Never attempt to modify any components of
the airbag system in any way.

A WARNING
Chi ld ren on the front seat of any car even w ith
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 ch ild 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 fac ing ch ild
safety seat on the front passenger seat in
exceptiona l circumstances and the
PA SSEN ­
G ER AIR BAG OFF
light does not come on
and stay on, immediately insta ll 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
If, in exceptional circumstances, you must in­
stall a forward-facing chi ld restraint on the
front passenger's seat :
- Always make sure the forward-fac ing seat
has been designed and certified by its man­
ufacturer for use on a front seat with a pas­
senger front and s ide a irbag .
- Always follow the manufacturer's instruc­
tions prov ided with the ch ild safety seat or
carrier.
- Always move the front passenger seat to
the highest position in the up and down ad­
justment range and move it back to the
rea rmost position in the seat's fore and aft
adjustment range, as fa r away from the air­
bag as possib le, before insta lling the for­
ward-facing child restraint .
- Always ma ke sure that the safety bel t upper
anchorage is behind the child restraint and
not next to or in front of the chi ld restraint
so that the safety belt will be properly posi­
t ioned.
Ch ild safety
-Always make sure that the PA SSENGER AIR
BAG OFF
light comes on and stays on all the
time whenever the ignition is switched on.
@ Tips
A lways replace child restraints that were in­
stalled in a vehicle during a crash. Damage to
a child restraint that is not v is ible could cause
i t to fai l in another collision situat ion.
Advanced front airbag system and children
Your vehicle is equipped with a front "Advanced
Airbag System" in compliance with Un ited States
Federal Motor Vehicle Safety Standa rd (FMVSS)
208, as we ll as Canada Moto r Vehicle Safety
Standard (CMVSS) 208 as app licab le at the time
your vehicle was manufactured.
T he Advanced A irbag system in you r vehicle has
been certified to meet the "low- risk" require­
ments fo r 3- and 6-year old ch ildren on the pas­
senger side and sma ll adu lts on the driver side.
T he low risk deployment criter ia are intended to
reduce the risk of injury t hrough 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 cert ified to comply with the
"supp ression" requirements of the Safety Stand­
ard, to turn off the front a irbag fo r infants up to
12 months who are restrained on the front pas­
senger seat in c hild rest raints t hat are lis ted in
the Standard.
E ven though your veh icle is eq uipped wit h an Ad­
vanced Airbag system, all ch ild ren, especially
those 12 yea rs and younger, should a lways ride
in the back seat proper ly 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-fac ing ch ild safety seat. It
can be a very dangerous place for an infant or a
larger ch ild in a rearward-facing seat .
135

Child safety
Advanced Airbags and the weight-sensing mat in the front seat
The Advanced Airbag System in your vehicle de­
tects the presence of an infant or child in a child
restraint on the front passenger seat using the
weight -sensing mat in the seat cushion and the
sensor below the safety belt latch on the front
passenger seat that measures the tension on the
safety belt .
The weight-sensing mat measures total weight
of the child and the child safety seat and a child blanket on the front passenger seat . The weight
on the front passenger seat is related to the de­
sign of the child restraint and its "footprint ", the
size and shape of the bottom of the child re­
straint as it sits on the seat. The weight of a child
restraint and its "footprint" vary for different
kinds of child restraints and for the different
models of the same kind of child restraint of­
fered by child restraint manufacturers.
The weight ranges for the individual types,
makes and models of child restraints that the
NHTSA has specified in the Safety Standard to­
gether with the weight ranges of typical infants
and typical 1 year-old child have been stored in
the control unit of the Advanced Airbag System .
When a child restraint is being used on the front
passenger seat with a typical 1 year-old child, the
Advanced Airbag System compares the weight
measured by the weight sensing mat with the in­
formation stored in the electronic control unit.
The electronic control unit also registers the ten­
sion on the front passenger safety belt. The ten­
sion on the safety belt for the front passenger
seat will be different for an adult who is properly
using the safety belt as compared to the tension
on the belt when it is used to attach a child re­
straint to the seat. The sensor below the latch for
the safety belt for the front seat passenger
measures the tension on the belt. The input from
this sensor is then used with the weight to "de­
cide" , whether there is a child restraint with a
typical 1 year-old child on the front passenger
seat and whether or not the airbag must be
turned off.
136
· Child restraints and Advanced Airbags
Regardless of the child restraint that you use,
make sure that it has been certified to meet Safe­
ty Standards and has been certified by its manu­
facturer for use with 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 child restraint is correctly recog­
nized by the weight-sensing mat inside the front
passenger seat, that the front passenger airbag
is turned off and that the airbag status is always
correctly signaled by the
PASSENGER AIR 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 and older models are taken out of
production. Child restraints are not standardized.
Child restraints of the same type typically have
differen t weights and si zes and different 'foot­
prints,' 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 National High­
way Traffic Safety Administration has published a
list of specific type, makes and models of child
restraints that must be used to certify compli­
ance of the Advanced Airbag System in your vehi­
cle with the suppression requirements of Federal
Motor Vehicle Safety Standard 208. These child
restraints are:

A WARNING
To reduce the risk of serious injury, make sure
that the
PASSENGER AIR BAG OFF light
comes on and stays on whenever a child re­
straint is installed on the front passenger seat
and the ignition is switched on.
Child safety
- Take the child restraint off the front passen­
ger seat and install it properly at one of the
rear seat positions if the
PASSENGER AIR
BAG OFF
light does not stay on.
- Have the airbag system inspected by your
authorized Audi dealer immed iately.
(D Tips
The child seats listed in categor ies A to C have
been statically tested by Audi only for the Ad­
vanced Airbag function.
Important safety instructions for using
child safety seats
Correct use of child safety seats substantially re­
duces the risk of injury in an accident!
As the driver, you are responsible for the safety
of everybody in the vehicle, especially children:
.,. Always use the right child safety seat for each
child and always use it properly ¢
page 140 .
.,. Always carefully follow the chi ld safety seat
manufacturer's instructions on how to route
the safety belt properly through the child safe­ ty seat.
.,. When using the vehicle safety belt to install a
child safety seat, you must first activate the
convertible locking r etractor on the safety belt
to prevent the chi ld safety seat from moving
~page 144.
.,. Push the chi ld safety seat down with yo ur full
weight to get the safety belt really tight so that the seat cannot move forward or sideways more than one inch (2.5 cm).
.,. If a strap or tether is being used to tie the child
safety seat to the front passenger seat, make
sure that it is not so tight that it causes the
weight-sensing mat to measu re more weight
than is actually on the seat.
.,. Secure unused safety belts on the rear seat
~page 139.
Always remember: Even though your veh icle is
equipped with an Advanced Airbag system, all
children, especia lly those 12 years and younger,
shou ld a lways ride in the back seat proper ly re-
strained for their age and s ize.

Child safety
Child safety seats
Infant seats
Babies and infants up to about one year old and
20 lbs. or 9 kg need special rearward -facing
child restraints that support the back, neck and
head in a crash.
Fig. 121 Schema tic overv iew: rearwa rd -facing infan t sea t,
properly installe d on the rea r seat
• When using the vehicle safety belt to install a
child safety seat, you must first activate the
convertible locking retractor on the safety belt
to prevent the child safety seat from moving
c::>poge 144 or install the seat using the LA TCH
attachments.
• Push the child safety seat down with your full
weight to get the safety belt really tight so that
the seat cannot move forward or sideways
more than one inch (2 .5 cm) .
• Secure unused safety belts on the rear seat
c::>page 139.
Infants up to about one year (20 lbs. or 9 kg) are
best protected in special infant carriers and child
safety seats des igned for their age group. Many
experts believe that infants and small children
should ride only in spec ial restraints in which the
child faces the back of the veh icle. These infant
seats support the baby 's back, neck and head in a
crash
