Airbag system
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
¢ page 130, 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
- The airbag indicator light in the instrument
panel
The airbag system is monitored electronically to
make ce rta in it is fun ction ing p roperly at all
times. Each time you turn on the ignit ion , 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 ion meas-
ured by the senso r is too low,
- in rear-end collisions,
- in rollovers.
A WARNING
-Safety belts and the a irbag system w ill only
provide protection when occupants are in
the proper seating position<>
page 59,
Seats and storage.
-If the airbag indicator light ¢page 19
comes when the vehicle is being used, have
the system inspected immediately by your
156
author ized 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. 159 Illustration of principle: Inflated sid e curtain air ­
bags on the left side
The side curtain airbags inflate between the oc­
cupant and the windows on the side of the veh i­
cle that is struck in a side collision
¢ fig . 159 .
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 protection, the
s ide curta in airbag must inflate within the blink
of an eye at very high speed and with g reat fo rce .
The side curtain airbag could injure you if yo ur
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 chi ldren
¢ page 158.
Although they are not a soft pillow, side curtain
airbags can "cushion" the impact and in this way
they can help to reduce the r isk 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.

..... N
0 ::..:: co ..... ..... 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.
_& 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 260, 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.
- 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 260, Addi­
tional accessories and parts replacement.
- Always sit in proper seating position and
wear safety belts while traveling so that the
Airbag system
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
If, in except ional 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 airbag .
- Always follow the manufac turer 's instruc­
tions provided with the chi ld safety seat or
carrier.
- Always move the passenger seat into its
rearmost position in the seat's fore and aft
adjustment range, as far away from the air­
bag as possib le before installing the child
restra int. The backrest must be adjusted to
an upr ight position.
-Always make sure that the
PA SSENGER AIR

Always replace ch ild restraints that were in­
stalled in a vehicle dur ing a crash. Damage to
a child restraint that is not visib le could cause
it to fail in another collision situation.
Advanced front airbag system and children
Your veh icle is equipped with a front "Advanced
A irbag System" i n compliance w ith United States
F edera l Moto r Vehicle Safety Standard ( FMVSS)
208, as well as Canada Motor Ve hicle Safety
Standard (CMVSS) 208 as applicable at the time
your vehicle was manufactured .
The Advanced Airbag system in your ve hicle has
been ce rtified to meet the " low-risk" requ ire­
ments for 3 -and 6-yea r old children on the pas ­
senger side and sma ll adults on the driver side .
Child safety
The low risk deployment criteria a re intended to
reduce the risk of injury through interaction with
the a irbag that can occur, for example, by be ing
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 ch ild rest raints that are listed in
the Standard.
Even though your veh icle is equipped with an Ad·
vanced Airbag system, all ch ild ren, especially
those 12 yea rs and you nger, sho uld 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 p lace for a
child to ride. The front seat is not the safest place
for a ch ild 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 .
' Advanced Airbags and the weight-sensing
mat in the front seat
The Advanced A irbag System in you r vehicle de ­
tects the presence of an infant or chi ld in a chi ld
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 tens ion on the
safety belt.
The weight-sensing mat measures total weight of the child and the chi ld safety seat and a child
blanket on the front passenger seat . The weight
on the front passenger seat is related to the de­
s ign of the child restra int and its "footprint", the
s ize and shape of the bottom of the ch ild re-
straint as it sits on the seat. The weight of a ch ild
restra int and its "footprint" va ry for different
k inds of child restra ints and for the different
models of the same kind o f chi ld rest raint of -
fered by chi ld restraint manufacturers.

makes and mode ls of ch ild restraints that the
NH TSA has specified in the Safety Standard to­
gether with the weight ranges of typical infants .,.

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 veh icle, especially children:
.,. Always use the right chi ld safety seat for each
child and a lways use it properly
q page 163 .
Child safety
.,. Always carefully follow the chi ld safety seat
manufacturer's instructions on how to route
the safety belt properly through the ch ild safe ­
ty 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 chi ld safety seat from moving
q page 167.
.,. Push the ch ild safety sea t 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 measure more weight
than is actually on the seat .
.,. Secure unused safety belts on the rear seat
q page 163.
Always remember: Even though your veh icle is
equipped with an Advanced Airbag system, all
c hi ldren, especia lly t hose 12 yea rs and younger,
sho uld a lways ride in th e back seat p roper ly re·
strained for their age and s ize.
A WARNING
=
Not using a child safety seat, using the wrong
chi ld safety seat or improperly insta lling a
chi ld restraint increases the risk of serious
personal injury and death.
- All vehicle occupants and especially children
must always be restrained properly whenev­
er riding in a vehicle.
- An unrestra ined o r improperly restrained
c hi ld can be injured o r killed by being
thrown aga inst the inside of the veh icle or
by being ejected from it during a sudden
maneuver or impact.
- An unrestra ined or improperly restrained
child is at much greater risk of injury or
death by being struck by an inflating air­ bag.
- Commercially availab le child safety seats
are requi red to comply with U .S. Federal
Motor Vehicle Safety Standard (FMVSS) 213
(in Canada CMVSS 213). ..,_

Child safety
-When buying a child restraint, select one
that fits your child and the vehicle.
- Only use child restraint systems that fully
contact the flat portion of the seat cush­
ion. The child restraint must not tip or
lean to either side. Audi does not recom­
mend using child safety seats that rest on
legs or tube-like frames . They do not pro­
vide adequate contact with the seat.
- Always heed all legal requirements per­
taining to the installation and use of child
safety seats and carefully follow the in­
structions provided by the manufacturer
of the seat you are using.
- Never allow children under 57 inches
(1.45 meters) to wear a normal safety belt.
They must always be restrained by a proper
child restraint system. Otherwise, they
could sustain injuries to the abdomen and
neck areas during sudden braking maneu­
vers or accidents.
- Never let more than one child occupy a child
safety seat.
- Never let babies or older children ride in a
vehicle while sitting on the lap of another
passenger .
- Holding a child in your arms is never a sub­
stitute for a child restraint system.
- The strongest person could not hold the
child with the forces that exist in an acci­
dent. The child will strike the interior of
the vehicle and can also be struck by the
passenger.
- The child and the passenger can also in­
jure each other in an accident.
- Never install rearward-facing child safety
seats or infant carriers on the front passen­
ger seat. A child will be seriously injured and
can be killed when the passenger airbag in­
flates -even with an Advanced Airbag Sys­
tem .
- The inflating airbag will hit the child safe­
ty seat or infant carrier with great force
and will smash the child safety seat and
child against the backrest, center arm
rest, door or roof.
- Always install rearward-facing child safety
seats or infant carriers on the rear seat.
162
-Forward-facing child safety seats installed
on the front passenger's seat can interfere
with the airbag when it inflates and cause
serious injury to the child . Always install for­
ward-facing child safety seats on the rear seat .
- 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 that the following
special precautions be taken:
- Make sure the forward-facing seat has been designed and certified by its manu­
facturer for use on a front seat with a pas­
senger front and side airbag .
- Always carefully follow the manufacturer's
instructions provided with the child safety
seat or carrier.
- Always move the front passenger seat into
the rearmost position of the passenger
seat's fore and aft adjustment range, and
as far away from the airbag as possible be­
fore installing the child restraint.
- 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.
- Always make sure that the backrest is in
the upright position.
- Always buckle the child safety seat firmly in
place even if a child is not sitting in it. A
loose child safety seat can fly around during
a sudden stop or in a collision.
- Always read and heed all WARNINGS when­
ever using a child restrained in a vehicle is
being used¢

A WARNING
Not using a ch ild safety seat, using the w rong
child safety seat or improperly installing a
child restraint increases the risk of serious
personal injury and death in a collision or oth ­
er emergency situation.
- Children on the front seat of any car, even with Advanced Airbags, can be seriously in­
jured or even killed when an airbag inf lates.
A ch ild 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 inflates -even with an Ad­
vanced Airbag System.
- The inflating a irbag w ill hit the child safety
seat or infant carrier with great force and
will smash the ch ild safety seat and chi ld
against the bac krest, center armrest, doo r
or roof.
- Always install rearward-fac ing ch ild safety
seats on the rear seat.
- If you must install a rearward fac ing ch ild
safety seat on the front passenger seat be­
c ause of exceptiona l circumstances and the
PASSENGER AIR BAG OFF light does not
come on and stay on, immediate ly install
the rearward-facing child safety seat in a
rear seating pos ition and have the airbag
system inspected by your authorized Audi
dealer.
- The rear side of the child safety seat should
be pos it ioned as close as poss ible to the
backrest on the vehicle seat. Adjust or re­
move the rear seat head restraint if it is d if-
Ch ild safety
ficult to insta ll the chi ld seat with the head
restraint in place¢
