Important safety instructions on
monitoring the Advanced Airbag System
A WARNING
-If the status of the Adv a need Airb ag Sys­
tem has changed while the vehicle is
moving, the
PA SS ENGER AIR B AG OFF
light b links for about S seconds to catch
t h e driv er's attent ion. If this happens, al­
ways stop as soon as it is safe to do so
and check the steps described above.
- If the
PAS SENGER AIR BAG OFF light
does not go off when an adult who is not
very small is sitting on the front passen­ ger seat after taking the steps descr ibed
above, make sure the adult is properly
seated and restrained at one of the rear seating pos it ions. Have the a irbag sys­
tem inspected by your authorized Audi
dealer before transporting anyone on the
front passenger seat.
A WARNING
An airbag system that is not funct ioning
properly cannot provide supplemental pro­
tection in a frontal crash.
- If the airbag indicator light
c> page 21
turns on when the vehicle is being used,
have the system inspected immediately
by you r autho rized Aud i dea le r. It is pos­
sible that the a irbag will inf late when it
is not s upposed to, or w ill not inflate
when it sho uld.
A WARNING
If the front airbag infla tes, a ch ild witho ut
a c hild restraint , or in a rearwar d-fac ing
child safety seat, or in a forward-facing
child rest raint that has not been properly
installed will be serio usly injured and can
be killed.

-Even tho ugh you r vehicle is equipped
with an Advanced A irbag System, make
certain that all children, espec ia lly 12
yea rs and younger, always ride on the
back seat prope rly restrained for their
age and size .
- Always install forward or rear-facing
child seats on the rear seat -even with
an Advanced A irbag System.
- I f you must install a rearwa rd-facing
child seat on the front passenger seat because of ex ceptio nal circumstances
and the

does not appear and s tay on, immediate­
ly install the rear -facing child seat in a
rea r seating pos ition and have the airbag
system inspected by you r Audi dealer.
- If, in exceptiona l circumstances, you
m ust install a forward-facing ch ild re­
straint on the front passenger seat, al­
ways move the seat into its rearmost po­
sition in the seat's fore and aft adjust­
ment range, as fa r away from the a irbag
as poss ible. The backrest must be adjust­
ed to an upright pos ition. Make su re that
the
PASSENGER AIR BAG OFF light
comes on a nd stays on all the time when­

your safety belt and wearing it properly. This
i s why you sh ou ld always wear your safety
be lt, not just because the law requires you to
do soc;,
page 131, General notes.
The safety belt buck le for the driver and front
seat passenger have switches that tell the a ir ­
bag control module if the safety belt is being
used or not.
Remember too, airbags will deploy only once
and on ly in certain kinds of accidents -your
safety belts are always there to offer protec­
tion in those acc idents in which airbags are
not supposed to deploy or when they have a l­
ready deployed, fo r example whe n your vehi­
cle strikes o r is str uck by another after the
fi rs t coll is ion.
This is just one of the reasons why an a irbag is
not a substitute for the safety belt. The airbag
sys tem works most effective ly when used with
the safety bel ts. Therefore, always wear your
safety bel ts correctly .
It is important to remember that whi le the

to redu ce the like lihood of serious injur ies,
o ther i njuries , fo r example , swell ing, bruising
and minor abras ions and frict ion burns ca n al­

The knee airbag system basically consists
of:
- T he electronic control mod ule
- T wo inflatab le airbags (airbag and gas gen-
erato r), o ne for the dr iver an d one for the
fron t passenger
- T he airb ag ind ic a tor light in the instrument

The knee airbag system will not deploy:
-when the ign ition is switc hed off
- in frontal collis ions when the decelerat ion
measured by the control unit is too low
- in side collisions
- in rear-end collisions
- in ro llovers -
in the event of a system malfunction (warn ­
ing/indicator light is on)¢

.&_ WARNING
--
-Safety belts and the airbag system can
only provide protection when occupants
are in the proper seating position

-If the airbag indicator light ¢page 21
turns on when the veh icle is be ing used,
have the system inspected immediately
by your authorized A udi dealer. It is pos­
sib le that the airbag will in flate when it
is not supposed to, or will not infla te
when i t should.
How knee airbags work
App lies to vehicles: with knee airbags
The risk of injury to the l eg area can be re­
duced by fully infla ted knee airbags .
Fig. 1 27 Inf lated airbags protect ing in a frontal colli­
s io n
The knee airbag system has been des igned so
that th e airbags for the driv er and front pas­
senger deploy in certa in but not all frontal
c ollisions.
If the front a irbags dep loy, the k nee a irbags
also dep loy in frontal col lis ions when the de­
ployment th reshold stored in the control un it
is me t.
When the system deploys, the a irbags fill
with a comp ressed prop ellant gas, and inflate

Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained occupants .
Fig. 128 Side a irbag locat ion in the dr iver 's seat
The sid e airbags are located in the sides of the
front seat backrests ¢
fig. 128 and the rear
backrest facing the doors.
The side airbags installed for the front seating
positions have been designed and certified to
help reduce the risk of injury that can be
caused by airbags when they inflate, particu­
larly when the occupant sitting next to it is
not seated properly. The side airbag for the
front passenger seat can be used with proper­ ly installed child restraints. Please be sure to
read the important information and warnings
whenever us ing a child restraint in a vehicle :
Safety belts
c::>page 131, Airbag system
c::>
page 140, Child safety ¢ page 166.
The side airbag system basically consists of:
-the electronic control module 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
cluster.
The airbag system is monitored electronically
to make certain that it is functioning properly
at all times. Each time you switch on the igni­
tion, the airbag system indicator light will
come on for a few seconds (self diagnostics) .
The side airbag system supplements the safe­
ty belts and can help to reduce the risk of in- jury
to the driver's, front and rear passenger's
upper torso on the side of the vehicle that is
struck in a s ide collision. The airbag dep loys
only in side impacts and only when the vehicle
accelerat ion reg istered by the control unit is
high enough. If th is rate is be low the refer ­
ence value p rogrammed into the control unit,
the side airbags will not be triggered, even
though the car may be badly damaged as a re­
sult of the collision.
It is not possible to de­
fine an airbag triggering range that will cover
every possible angle of impact, since the cir ­
cumstances will vary considerably between
one collis ion and another. Important factors
include, for example, the nature (hard or soft)
of the impacting object , the angle of impact,
vehicle speed, etc.¢
page 161, Important
safety instructions on the side airbag system .
Aside from their normal safety function, safe­
ty belts work to help keep the driver or front
passenger in position in the event of a side
collision so that the side airbags ca n provide
protection.
The airbag system is
not a substitute for your
safety belt. Rather, it is part of the overall oc ­
cupant restraint system in your vehicle. Al­
ways remember that the side ai rbag system
can only help to prote ct you if you are wearing
yo ur safe ty belt and wearing it properly. This
is another reason why you should always wear
your safety belts, not just because t he law re­
quires yo u to do soc::>
page 131, General
notes.
It i s important to remember that while the
supplementa l side airbag system is designed
to reduce the likelihood of serious injuries,
other injuries, for example, swelling, bru is ing,
friction burns and m inor abrasions can a lso be
associated w ith deployed side airbags . Re­
member too, side a irbags w ill deploy only
once and only in ce rtain kinds of accidents -
you r safety belts are always the re to offer pro­
tection.
Vehicle damage, repair costs or even the lack
of vehicle damage are not necessarily an indi ­
cation of over-sensitive or failed airbag activa-
tion. In some coll isions, both front and side

-Always sit in an upright position and
never lean against the area where the
supplemental 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.
- 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 replace­
ment upholstery over the front seat­
backs that have not been specifically
approved by Audi.
- Never use additional seat cushions that
cover the areas where the side airbags
deploy.
- Damage to the original seat covers or
to the seam in the area of the side air­
bag module must always be repaired
immediately by an authorized Audi
dealer.
- Objects between you and the airbag can
increase the risk of injury in an accident
by interfering with the way the airbag
unfolds or by being pushed into you as
the airbag inflates .
- Never place or attach accessories or
other objects (such as cup holders, tel­
ephone 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 be­
come dangerous projectiles and cause
injury when the supplemental side air­
bag deploys.
- Never carry any objects or pets in the
deployment space between them and
the airbags or allow children or other passengers 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 air­
bag deployment and can cause personal
injury in an accident.
- Always prevent the side airbags from be­
ing damaged by heavy objects knocking
against or hitting the sides of the seat­
backs.
- The airbag system can only be triggered
once . If the airbag has been triggered,
the system must be replaced by an au­
thorized 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 au­
thorized Audi dealer.
- If children are seated improperly, their
risk of injury increases in the case of an
accident
¢ page 166, Child Safety.
-Never attempt to modify any compo­
nents of the airbag system in any way.
- In a side collision, side airbags will not
function properly if sensors cannot cor­
rectly measure increasing air pressure in­
side the doors when air escapes through
larger, unclosed openings in the door
panel.
- Never drive with interior door trim pan­
els removed .
- Never drive when parts have been re­ moved from the inside door panel and
the openings they leave have not been properly 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
workshop.

Side curtain airbags
Description of side curtain airbags
The side curtain airbag system can provide
supplemental protection to properly restrain ­
ed occupants .
Fig. 130 Side cu rt ain airbags , d ri ver 's side : side curtain

The s ide cur tain airbags a re located on both
sides of the inte rior above the front and rear
side w indows ¢
fig. 130. They are ident ified
by the word "AIRBAG" on t he windshie ld
frame and the center roof pi llar.
The s ide cur tain airbags contain features that
prov ide e jection m itigation to he lp prevent ve­
h icle occupants or parts of their bodies from
being completely or partially ejected from the
ve hicle interior in certain side impacts and ve­
h icle rollovers.
The side curtain airbag system supp lements
the safety belts and can help to reduce the risk of injury for occupants ' heads and upper
t orso on the side of the vehicle that is struck
in a side collision . The side curta in a irbag in ­
flates in s ide impacts and on ly when the veh i­
cle acce le rat ion reg istered by the contro l uni t
i s hig h enoug h. If th is rate is below the refe r­
e n ce value programmed into the con trol un it,
the side c urtain airbag 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 airbag triggering range that will
cover every possible angle of impact, since the
circumstances will vary considerably betwee n
one collision and another . Important factors
include, for examp le, the nature (hard or soft)
of the impacting object, the angle of impact ,

164 Airbag system
-in rear-end collisions .
~ WARNING
-Safety belts and the a.irbag system wi ll
only provide protection when occupants
are in the proper seating posit ion
q page 53, Front seats.
- If the airbag indicator light q page 21
turns on when the vehicle is being used,
have the system inspected immediately
by your authorized Aud i dealer . It is pos­
sible that the airbag will inflate when it
is not supposed to, or w ill 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 restrained.
-
Fig. 131 Illustrat ion of p rinciple: Inf lated side cu rta in
airbags on the left side
The s ide curtain airbags inflate between the
occupant and the windows on the side of the
vehicle that is struck in a side collision
qfig. 131.
When the system is triggered, the side 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 or­
der to help provide this additional protection,
the side curtain airbag must inflate within the
blink of an eye at very high speed and w ith
g reat force. The side curtain airbag could in­
jure you if your seat ing position is not proper
or upright or if items are located in the area
where the supplementa l side curtain airbag inflates
. This applies especially to chi ldren
qpage 166.
Although they are not a soft pillow, side cur­
tain airbags can "cushion" the impact and in
this way they can help to reduce the risk of in­
jury to the head and the upper part of the
body.
A fine dust may develop when the airbag de­
ploys. 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 . Al­
ways 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 wea ring safety belts and im­
proper seating pos it ion s increase the risk
of serious personal injury and death when­
ever a vehicle is being used.
- Never let occupants place any parts of
their bodies in the area from which the
side curtain airbag inflate.
- Always make sure that the sid e curtain
airbags can inflate without interference.
- Use the bu ilt-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 colli­
sion.
- 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, ga­
rage door openers, hands-free speakers,
-

-Always install rear-facing child safety
seats on the rear seat.
- If you must install a rearward facing
child safety seat on the front passenger
seat in 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 air­
bag system inspected immediately by
your Audi dealer.
_& 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 follow­
ing special precautions to be taken:
- Always make sure that the forward-fac­
ing seat has been designed and certi­
fied by its manufacturer for use on a
front passenger seat with a front and side airbag.
- Always carefully follow the manufac­
turer'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 in­
structions require the top tether strap
to be used.
- Never put the forward-facing child re­
straint up against or very near the in­
strument panel.
- Always set the safety belt upper an­
chorage to the adjustment position
that permits proper installation in ac­
cordance with the child restraint manu­
facturer's instructions.
- Always move the passenger seat into
its rearmost position in the seat's fore
and aft adjustment range, as far away
.
Child Safety 167
from the airbag as possible before in­
stalling the child restraint. The back­
rest must be adjusted to an upright po­
sition.
- Always make sure that nothing pre­
vents 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 device, power inverter or seat
heater for child seats). These may in­
fluence the electrical capacitance
measured by the capacitive 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
heater for child seats) on the front pas­
senger 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 passen­ ger seat, never install any child re­
straint system on this seat.
- Make sure that there are no wet objects
(such as a wet towel) and no water or
other 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, immedi­
ately 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.

WARNINGS. Make certain that the chi ld and
chi ld restraint are correct ly recognized by the
capacitive passenger detect ion system in the
front passenger seat, that the front passenger
airbag is turned
off, and that the airbag status
is always correct ly signaled by the
PAS SEN­
GER AIR BAG OFF
light .
Many types and models of child restra ints
have been ava ilable over the years, new mod­
e ls are introduced regular ly incorporating new
and improved designs and older models are
taken out of production . Child restraints are
not standardized. Ch ild restra ints of the same
type typically have different we ights and s izes
and d ifferent "footprints", the size and shape
of the bottom of the child restraint that sits
on the seat, when they are installed on a vehi­
cle seat. These differences make it virtually imposs ible to certify compliance w ith the re­
qu irements for advanced a irbags 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
H ighway Traffic Safety Administration has
published a list of specific type, makes and
models of child restraints that must be used
to certify compliance of the Advanced Airbag
System in your vehicle with the supp ress io n
requirements of Federa l Motor Vehicle Safety
Standard 208 . These child restraints are:
