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
PASSENGER AIR BAG OFF
light b links for about S seconds to catch
the driver'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
PASSENGER 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

comes when the vehicle is be ing 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 child restraint, or in a rearward -facing
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.

162 Airbag system
Remember too, airbags will deploy only once
and on ly in certain k inds of accidents -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 al­
ready deployed, for example when your veh i­
cle strikes or is struck by another after the
first coll is 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 be lts correctly .
It is important to remember that while the
supplemental knee airbag system is designed
to reduce the likelihood of serious injuries,
other injuries , for example , swell ing, bruising
and minor abrasions and friction burns can al­
so occur when an airbag inflates.
The knee airbag system basically consists
of:
- The elec tronic con trol module
- T wo inflatab le airbags (airbag and gas gen-
erator), one fo r the driver and one for the
front passenger
- T he airbag indicator light in the instrument
panel
The knee airbag system will not deploy:
-when the ign ition 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
- i n the event of a system malfunction (warn-
i ng/indicator light is on)
Q page 21.
.8, WARNING
-Safety belts and the airbag system can
only provide protection when occupants
are in the proper seating posit ion
Q page 154.
-If the airbag indicator light¢ page 21
comes when the vehicle is be ing used,
have the system inspected immediately
-
by your authorized Audi dealer. It is pos­
sible that the airbag will inflate when it
is not supposed to, or will not inflate
when it should .
How knee airbags work
Applies to vehicles: wi th knee airbags
The risk of injury to the leg area can be re ­
duced by fully inflated knee airbags.
Fig . 134 Inflated a irbags protecting in a fronta l co lli­
sion
The knee airbag system has been designed so
that the airbags for the driver and front pas ­
senger deploy in certa in but not all frontal
collisions.
If the front airbags dep loy, the knee airbags
also dep loy in frontal collisions when the de­
ployment threshold stored in the control unit
is met.
When the system deploys, the airbags fill
with a compressed propellant gas, and inf late
between the lower part of the instrument
panel and the driver and the lower part of the
instrument panel and the front passenger
Qpage 154, fig. 131 .
Although they are not a soft pillow, they can
"cushion" the impact and in th is way they can
help to reduce the risk of injury to the lower
extremit ies .
All of th is takes place in the blink of an eye, so
fast that many people don't even realize that
the a irbags have deployed . The airbags also
i nflate with a great deal of force and it is im­
portant for occupant safety that nothing
shou ld be in their way when they deploy. ..,.

caused by airbags when they inflate, particu ­
l ar ly when the occupant sitting next to it is
not seated proper ly. The s ide a irbag for the
front passenger seat can be used with proper­ ly installed child restraints. Please be sure to
read the important information and warnings
wheneve r us ing a ch ild restrai nt in a vehicle:
Safety belts~
page 135, Airbag system
~ page 144, Child safety ~ page 170.
The si de ai rbag system ba sically con sists of:
- the e lectronic control module and external
s ide 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 elect ronica lly
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).
T he side airbag system supplements the safe­
ty belts and can help to reduce t he 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 side collision . The airbag deploys
only in s ide impacts and o nly when the veh icle
acceleration registered by the control un it is
h igh enough . If this rate is below the refer­
ence va lue programmed into the control u nit,
the side airbags will not be triggered , even
though the ca r may be badly damaged as a re ­
sult of the collision . It is not possible to de­
f ine an a irbag tr igger ing range that will cover
every possible angle of impact, since the cir­
cumstances will vary considerably between
one co llision and another . Important factors
include, for examp le, the nature (hard or soft)
of the impacting object, the ang le of impact ,
ve hicl e speed, etc.
~ page 165, Impor tant
safety instructions on the side airbag system.
Aside from the ir normal safety function, safe­
ty belts work to he lp keep the driver or front
passenger in position in the event of a side collision so that the side airbags can provide
protection.
T he airbag system is
not a substi tute for you r
sa fety belt . Rather, it is part o f the overa ll oc­
c u pant restra int system in you r vehicle . A l­
ways remember that the side airbag system can only help to protect you if you are wearing
your safety belt and wearing it proper ly. This
is another reason why you should always wear
your safety belts, not just because the law re ­
quires you to do so~

notes.
I t is important to remember that w hile the
supplementa l side airbag system is designed
to reduce the likelihood of ser ious inju ries,
other injur ies, for example, swelling, bru is ing ,
fr iction burns and m ino r abrasions can a lso be
associated w ith dep loyed side airbags. Re­
member too, side a irbags w ill dep loy on ly
once and on ly in ce rtain kinds of accidents -
your safety belts a re always the re to offer pro­
tection .
Vehicle damage , repair costs or even the lack
of ve hicle damage are not necessarily an indi ­
cation of over-sensitive or failed airbag activa­
t ion. In some coll is ions, both front and side
airbags may inflate. Remember too, that air­
bags will deploy only once and only in certain
k inds of collisions -your safety belts are a l­
ways the re to offer p rotection in those acc i­
dents in which airbags are not supposed to
deploy or when they have a lready deployed .
The side airbag system will not deploy:
-when the ignit ion is switched off
- in side co llisions when the acceleration
measured by t he senso r is too low
- in front-end collisions
- in rear-end co llisions
- in rollove rs .
In some types of accidents the front airbags,
s ide cu rtain airbags and s ide a irbags may be
t rigge red togethe r.

_& WARNING
-Safety belts and the airbag system will
only provide protection when occupants
are in the proper seating position
¢page 165.
-If the airbag indicator light¢ page 21
turns on when the vehicle is being used,
have the system inspected immediately
by your authorized Audi dealer.
It is pos­
sible that the airbag will inflate when it
is not supposed 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.
Fig. 136 Side impac t protectio n: in flated side a irbags
When the system is triggered, the airbag is
filled with propellant gas and breaks through
a seam in the seat surface area marked "AIR­
BAG" . It expands between the side trim panel
and the passenger. In order to help provide
th is additional protection, the side airbag
must inflate within a fraction of a second at
very high speed and with great force. The sup­
plemental side airbag could injure you if your
seating position is not proper or upright or if
items are located in the area where the sup­
plemental side a irbag expands . This applies
especially to children ¢

Important safety instructions on the
side 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 act accordingly to help the
safety belts and airbags do their job to pro­
vide supplemental protection .
_& WARNING
-An inflating side airbag can cause serious
or fatal injury. Improperly wearing safety
belts and improper seating positions in­
crease the risk 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
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.

166 Airbag system
-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 if the supplemental side airbag
inflates .
- 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
Q page 170, 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.

0 > co ,....,
The inflatable side curtain airbags are located
on both sides of the interior above th e front
and rear side windows . T hey are identified by
the word "AIRBAG" on the windsh ield frame
and the center roof pillar.
The side curtain airbags contain features that prov ide ejection m itigation to he lp prevent ve­
h icle oc cupant s or parts of their bodies from
being comple tely or partially ejected from the
vehicle interior in certain side impacts and ve ­
h icle rollovers .
The s ide curtain airbag system supp lements
the safety belts and can help to reduce the risk of injury for occupa nts ' heads and upper
torso on the side of the veh icle that is struck
i n a side collision . T he side curta in a irbag in­
flates in s ide impacts and on ly w hen the veh i­
cle acce le rat ion reg iste red by the cont ro l u nit
is high enough . If this rate is below the refer ­
ence value programmed into t he control unit,
the side c urtain airbag will not be t riggered,
even though the car may be badly damaged as
a result of the collision. It is not possible to
define an airbag triggering range tha t will
cover every possible angle of impact, since the
circumstances will vary considerably between
one co llision and another. Important factors
i nclude, for examp le, the natu re (hard o r soft)
of the impacting object, the ang le o f impact ,
ve hicl e speed, et c.
q page 168, How sid e cur ­
tain airbags work .
Besides their normal safety f unction, safety
be lts work to help keep the dr iver or front
passenger in position in the event of a frontal
collision so that the side curtain airbags can provide protection.
The airbag system is not a s ubst itute for yo ur
safety be lt . Rathe r, it is pa rt of the overall oc ­
cupant restraint system in your vehicle . Al­
ways rememb er that the airbag system can
only help to protect you if you are wearing
your safety belt and wear ing it properly. Th is
is another reason why you shou ld always wear
your safety belts, not just because the law re ­
q uir es you to do so

It is important to remembe r that wh ile the
side curtain airbag system is designed to help
reduce the likelihood of ser ious injuries, other
injur ies, for example, swelling, bru is ing, fric­
tion burns and minor abras ions can also be as­
sociated w ith these airbags upon deployment .
Remember too , these airbags will deploy only
once a nd only in ce rtain kinds of accide nts -
you r safety be lts a re a lways the re to offer p ro­

side impact sensors
- The side curta in a irbags above the front and
rear s ide windows w it h ejection mitigation
featu res
- The a irbag indicator light in the instr ument

The airbag system is mon itored e lectronically
to make ce rtain it is func tioning prope rly at all
times. Each time you sw itch on the ig nition,
the air bag system indicator light will come on
f o r a few se conds (sel f diagnos tic s) .
The side curtain airbag is not activat ed:
- if the ignition is sw itched off,
- in side collisions whe n the acceleration
measured by the sensor is too low,
- in rear-end collisions.
A WARNING
-Safety belts and the airbag system will
only provide pro tection when occupa nts
are in the proper seating position

168 Airbag system
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. 138 Illustration of p rincipl e: In flated s ide curt ain
airbags on th e Left side
The side curtain airbags inflate between the
occupant and the windows on the side of the
vehicle that is struck in a side collision
c::> fig. 138.
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 pro tection,
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 in­
jure you if your seating position is not proper or upright or if items are located in the area
where the supplemental side curtain airbag
inflates . This applies especially to children
<=:> page 170.
Although they are not a soft pillow, side cur­
tain airbags can "cushion" the impact and in
this way they can he lp 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 norma l 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 o
proper seating position.
There is a lot that you and your passengers
must know and do to he lp the safety belts and
airbags do their job to provide supp lemental
protection.
A WARNING
Improperly wearing safety belts and im­
proper seating positions 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 side curtain
airbags 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 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 Aud i
sun shades.
- Never swing the sun visors over to the
side windows if things such as pens, ga­ rage door openers , hands-free speakers,
etc. are attached to the sun visors. They
could come loose and cause serious in­
jury if the side curtain 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.
- The airbag deployment zones must be
kept clear at all times. Make sure there
are no objects, pets, or other persons in
-
