Airbag system Important information
Importance of wearing safety belts and
sitting properly
Airbags are only supplemental restraints. For
airbags to do their job, occupants must always
properly wear their safety belts and be in a prop­
er seating position.
For your safety and the safety of your passen­
gers, before driving off, always :
.,. Adjust the driver's seat and steering wheel
properly~ page 250,
.,. Adjust the front passenger's seat properly
~page 251,
.,. Wear safety belts properly ~page 263,
.. Always properly use the proper child restraint
to protect children
r=> page 294.
In a collision, airbags must inflate within the
blink of an eye and with considerable force. The
supplemental airbags can cause injuries if the
driver or the front seat passenger is not seated
properly. Therefore in order to help the airbag to
do its job, it is important, both as a driver and as
a passenger to sit properly at all times .
By keeping room between your body and the
steering wheel and the front of the passenger
compartment, the airbag can inflate fully and
completely and provide supplemental protection in certain frontal collisions
r=> page 250, Correct
passenger seating positions .
For details on the
operation of the seat adjustment controls
r=>page 59.
It's especially important that children are proper­
ly restrained
r::> page 294 .
There is a lot that the driver and the passengers
can and must do to help the individual safety fea­
tures installed in your Audi work together as a
system .
Proper seating position is important so that the
front airbag on the driver side can do its job. If
you have a physical impairment or condition that prevents you from sitting properly on the driver
seat with the safety belt properly fastened and
Airbag system
reaching the pedals, or if you have concerns with
regard to the function or operation of the Ad­
vanced Airbag System, please contact your au­
thori zed Audi dealer or qualified workshop, or
call Audi Customer Relations at 1-800-822-2834
for possible modifications to your vehicle.
When the airbag system deploys, a gas generator
will fill the airbags, break open the padded cov­ ers, and inflate between the steering wheel and
the driver and between the instrument panel and
the front passenger. The airbags will deflate im­
mediately after deployment so that the front oc­
cupants can see through the windshield again
without interruption.
All of this takes place in the blink of an eye, so
fast that many people don't even realize that the
airbags have deployed. The airbags also inflate
with a great deal of force and nothing should be
in their way when they deploy. Front airbags in
combination with properly worn safety belts slow
down and limit the occupant's forward move­
ment . Together they help to prevent the driver
and front seat passenger from hitting parts of
the inside of the vehicle while reducing the forces acting on the occupant during the crash . In this
way they help to reduce the risk of injury to the
head and upper body in the crash. Airbags do not
protect the arms or the lower parts of the body.
Both front airbags will not inflate in all frontal
collisions . The triggering of the airbag system de­
pends on the vehicle deceleration rate caused by
the collision and registered by the electronic con­
trol unit . If this rate is below the reference value
programmed into the control unit, the airbags
will not be triggered, even though the car may be badly damaged as a result of the collision. Vehi­
cle damage, repair costs or even the lack of vehi­
cle damage is not necessarily an indication of
whether an airbag should inflate or not .
Since the circumstances will vary considerably between one collision and another, it is not possi­
ble to define a range of vehicle speeds that will
cover every possible kind and angle of impact
that will always trigger the airbags . Important
factors include, for example, the nature (hard or
soft) of the object which the car hits, the angle of
impact, vehicle speed , etc. The front airbags will

Airbag syste m
also not inflate in side or rear co llisions, or in
ro ll- overs.
Alwa ys rem ember : Airbags will deploy only once,
and on ly in ce rtain k inds of coll is ions. Yo ur safety
be lts are always there to offer protection in those
situations in which airbags are not supposed to
deploy, or when they have already deployed; for
examp le, when your vehicle str ikes or is struck by
another vehicle after the first collision.
This is just one of the reasons why an airbag is a
supplementary restraint and is not a substitute
for a safety belt. The a irbag system works most
effect ively when used with the safety belts.
Therefore, always properly wear your safety belts
r;:;, page 260 .
A WARNING
Sitting too close to the steering wheel o r in­
st rument panel will decrease the effective­
ness of the airbags and will inc rease the risk
of personal injury in a co llision.
- Never sit closer than 1 0 inches (25 cm) to
the steering wheel or instrument panel.
- If you cannot sit mo re than 10 inches
( 2 5 cm) from the steering wheel, invest i­
gate whether adaptive equipment may be
available to help yo u reach the pedals and
increase your seating distance from the
steering wheel.
- All vehicle occupants and especially children
must be restrained properly whenever riding
in a vehicle. An unrestrained or improperly
restra ined 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 imp roperly restrained
child is also at greate r risk of inju ry or death
through contact with an infla ting airbag .
-If you are unrestrained, leaning fo rwa rd, s it­
t ing s ideways or o ut o f pos ition in any way,
yo ur risk of in ju ry is much h igher.
- Yo u will also receive serious injuries and
could even be killed if you are up aga inst the
air bag or too close to it when it inflates -
even with an Advanced Airbag.
270
-
- To reduce the r is k of i njury when an a irbag
inflates, always wear safety belts prope rly
r;:;, page 264, Safety belts.
- Always make certa in that children age 12 or
younge r always ride in the rear seat. If chil­
dren are not properly restrained, they may be severely injured or killed when an airbag
inflates.
- Never let ch ildren r ide unrestra ined or im­
properly restrained in the vehicle . Ad just the
front seats properly .
- Never ride with the back rest recl ined .
- Always sit as far as possible from the steer-
ing wheel or the instrument panel
r;:;, page 250 .
-Always sit upright w ith your back against
the backrest of your seat .
- Never p lace your feet on the instrument
panel or on the seat . Always keep both feet
on the floor in front of the seat to help pre­
vent serious injur ies to the legs and hips if
the airbag inflates.
- Never recl ine the front passenger's seat to
transpo rt objects . Items can also move into
the area of the s ide airbag or the front air­
bag du ring brak ing o r in a sudden maneu­
ver . Obje cts nea r the airbags can become
pro jecti les and cause injury when an airbag
inflates.
A WARNING
Airbags that have deployed in a crash m ust be
replaced.
- Use on ly original equipment airbags ap­
proved by Audi and installed by a trained
technician who has the necessary tools and
diagnostic equipment to properly replace
any airbag in yo ur vehicle and assure system
effectiveness in a crash.
- Never perm it salvaged or recycled airbags to
be installed in your vehicle .

Airbag syste m
Always remember, a child seat or infant carrier
installed on the front seat may be struck and
knocked out of position by the rapidly inflating
passenger's airbag in a frontal collision. The air­
bag could greatly reduce the effectiveness of the
child restraint and even seriously injure the ch ild
during inflation .
For this reason, and because the back seat is the
safest place for children
-when properly restra in­
ed according to the ir age and size
-we strongly
recommend that children always sit in the back
seat ¢ page 294, Child safety.
.8, WARNING
A child in a rearward-facing chi ld seat insta l­
led on the front passenger seat will be ser i­
ously injured and can be killed if the front air­
bag inflates
-even with an Advanced Airbag
System.
- The inflating a irbag w ill hit the child seat or
infant carrier with great force and will
smash the chi ld seat and child against the
backrest, center armrest, door or roof.
- Always install rear-facing child
seats on the
rear seat.
- If you must install a rearward facing chi ld
seat on the front passenger seat because of
exceptional c ircumstances and the
PASSEN­
GER AIR BAG OFF
light does not come on
and stay on, immediately insta ll the rear­
facing child seat in a rear seating position
and have the airbag system inspected by
yo ur Audi dealer.
- Forward-facing ch ild seats insta lled on the
front passenge r's seat may interfe re with
the deployment of the airbag and cause se­
rious persona l injury to the child.
.8, WARNING
If, in except ional circumst ances, you must in­
stall a forward-facing chi ld restraint on the
front passenger's seat:
- Always make sure the forward-facing se at
has been designed and ce rt ified by its man ­
ufact urer for use on a front seat with a pas­
senger front and side a irbag .
272
-
- Never put the fo rwa rd-facing child restraint
up against or very near the instrument pan­
el.
- Always move the front passenge r seat to
the highest posit ion in the up and down ad­
justment range and move it back to the
rearmost posit ion in the seat's fo re and aft
ad justmen t range, as far away from the a ir­
bag as poss ible, before installing the for­
ward-f acing chi ld restrain t.
- Always make sure that the safety be lt upper
anchorage is behind the ch ild rest raint and
not next to o r in fron t of the child rest raint
so th at the s afety be lt will be p roperly posi­
tioned.
- Ma ke sure th at the
PASSENGER AIR BAG
OFF
light comes on and stays on a ll the time
wheneve r the ignit ion is switched on .
.8, WARNING
To reduce the risk of serious injury, ma ke sure
that the
PASSENGER AIR BAG OFF light will
be d isp layed whenever a ch ild rest raint is in­
stalled on the front passenge r seat and the
ignition is switched on.
- If the
PASSENGER AIR BAG OFF light does
not stay on, perform the checks described
¢ page 281 , Monitoring the Advanced Air­
bag System.
- Take the child restra int off the front passen­
ge r seat and install it properly at one of the
rear sea t positions if the
PASSENGER AIR
BAG OFF
light does not stay on.
- Have the ai rbag system inspec ted by your
Aud i dea le r i mmediately.
- Always carefully follow ins tructions from
child restraint manufacture rs when instal­
ling child restra ints .
.8, WARNING
I f, in exceptional ci rcumstances, you must in­
stall a forward or rearward-fa cing child re­
str aint on the fron t passenger's seat:
- Improper installat ion of child res traints can
redu ce the ir effectiveness or even preven t
them from provid ing any pro te ct ion .

-An improper ly installed child restraint can
interfere with the airbag as it deploys and
seriously injure or even kill the child
-even
with an Advanced Airbag System.
- Always carefully follow the manufacturer's
instructions provided with the child seat or
carrier .
- Always make sure that there is nothing on
the front passenger seat that will cause the capacit ive passenger detection system in
the seat to signal to the Airbag System that
the seat is occupied by a person when it is
not, or to signal that it is occupied by some­
one who is heavier than the person actually
sitting on the seat. The presence of addi­
tional objects could cause the passenger
front airbag to be turned on when it should be off, or could cause the airbag to work in a
way that is different from the way it would have worked without the object on the seat .
Front airbags
Description of front airbags
The airbag system can provide supplemental
protection to properly restrained front seat occu­
pants.

Your vehicle is equipped with an "Advanced Air­
bag System" in compliance with United States
Federal Motor Vehicle Safety Standard
(FMVSS) 208, as well as Canada Motor Vehicle
Safety Standard (CMVSS) 208 as applicable at
the time your veh icle was manufactured.
The airbag for the driver is in the steering wheel
hub
¢ fig. 236 and the airbag for the front pas­
senger is in the instrument panel
¢fig . 237. The
general location of the airbags is marked "AIR­
BAG ".
There is a lot you need to know about the airbags
in your vehicle . We urge you to read the detailed
information about airbags, safety belts and child
safety in this and the other chapters that make
up the owner's literature. Please be sure to heed
the WARNINGS
-they are extremely important
for your safety and the safety of your passengers,
especially infants and small children.
_& WARNING
-Never rely on airbags alone for protection .
- Even when they deploy, airbags provide only
supplemental protection.
- Airbag work most effectively when used
with properly worn safety belts.
- Therefore, always wear your safety belts and
make sure that everybody in your vehicle is
properly restrained.
- Always hold the steering wheel with both
hands on the outside of the steering wheel
rim at the 9:00 o'clock and 3:00 o'clock po­
sitions to help reduce the risk of personal in-
jury if the driver's airbag inflates.
..,.
273

Airbag syste m
-Never hold the steering whee l at the 12
o'clock pos it ion or w ith your han ds any­
where inside the steering wheel or on the steering wheel hub. Holding t he steering
wheel the wrong way increases the risk of severe injury to the arms, hands, and head if
the d river a irbag deploys.
A WARNING
Objects between you and the a irbag w il l in­
crease the risk of inj ury in a crash by interfer­
ing w ith the way the airbag unfo lds and/or by
being pushed into you as the airbag inflates .
- Always make sure nothing is in the front air-
bag deployment zone that could be str uck
by the airbag when it inflates.
-
- Objects in the zone of a deploying airbag
can become projectiles when the airbag de ­
ploys and cause serious persona l injury .
- Never hold th ings in your hands or on your
lap when the vehicle is in use.
- Never place accessor ies or other objec ts
(s uch as c up ho lders, telephone brackets,
note pads, navigation systems, or things
that are large, heavy, o r bulky) on the doors;
never attach then to the doors or the wind­
shield; never place them over or near or at­
tach them to the area marked
,,AIRBAG" on
the steering wheel, instrument panel or the seat backrests; never p lace them between
these a reas and yo u or any other person in
the vehicle.
- Never attach objects to the w indshield
above the passenger front airbag, s uch as
accessory GPS navigation uni ts or mus ic
players . S uch objects could ca use serio us in ­
jury in a collision, especially when the air­ bags inflate.
- Never recline the front passenger seat to transport objects . Items can also move into
the deployment area of the side a irbags or
the front a irbag during breaking o r in a sud­
den maneuver. Objects near the airbags can
fly dangerous ly through the passenger com­
partment and cause injury, particularly
when the seat is reclined and the airbags in­
flate.
274
A WARNING
A person on the front passenger seat, espe­
cially infants and small ch ildren, wi ll receive
serious in juries and can even be k illed by be­
ing too close to the airbag when it inflates .
- Although the Advanced Airbag System in your veh icle is designed to turn off the front
passenger airbag if an infant o r a small child
is on the fron t passenger sea t, nobody can
absolu tely guarantee tha t deployment un­
de r these specia l condi tions is impossible in
all conceivable situations that may happen
during the useful life of yo ur vehicle.
- The Advanced Airbag System can dep loy in
accordance with the
,. low risk" option for 3-
and 6-year-old children under the U.S. Fed­
eral Standard if a child w ith electrical capac­
itance greater than the combined capac i­
tance of a typical one-year o ld infant re­
strained in one of the forward facing or rea r­
ward-facing chi ld seats with which yo ur ve­
hicle was certified is on the front passenger
seat and the o ther conditions for airbag de-
ployment are me t.
- Accident s tatisti cs have shown th at children
are generally safer in the rear seat are a than
in the front seat ing pos ition.
- For their own s afety, all ch ildren, especi ally
12 years and younger, should alw ays ride in
the back proper ly restrained for their age
and size .
Advanced front airbag system

cle was manufactu red .
The front Advanced A irbag System supplements
the safety belts to provide add itiona l protect ion
for the driver 's and front passenger's heads and
upper bod ies in fronta l crashes. The a irbags in­
flate only in frontal impacts when the vehicle de-
ce le ra tion is high e no ugh.

your risk of injury is much h igher.
- You will also receive serious injuries and
could even be killed if you are up aga inst the
airbag or too close to it when it inflates -
even with an Advanced

A WARNING
A child in a rearward -facing child seat instal­
led on the front passenger seat will be ser i­
ously inju red and can be killed if the front air­
bag inflates - even with an Advanced Airbag
System.
- Although the Advanced A irbag System in
yo ur vehicle is designed to tu rn off the front
airbag when a rearward-facing child re­
straint has been insta lled on the front pas ­
senger seat, nobody can absolutely g uaran­
tee that deployment is impossible in all con­ ceivable s ituations that may happen during
the useful life of your vehicle.
- The inflating airbag will hit the child seat or infant carrier w ith great force and will
smash the ch ild seat and child against the
backrest, center armrest, door, or roof .
- Always install rearward-facing ch ild re­
straints on the rear seat .
- If you must install a rearward fac ing ch ild
seat on the front passenger seat because of
exceptional c ircumstances and the

and have the airb ag system inspected by
yo ur 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 -facing seat
has been designed and certified by its man­
ufacturer for use on a front seat with a pas­
senger front and side a irbag.
276
-
- Never put the fo rward-facing child restraint
up against or very near the instrument pan­
el.
- Always move the front passenger seat to
the highest posit ion in the up and down ad­
justment range and move it back to the rearmost posit ion in the seat's fore and aft
ad justment range, as far away from the a ir­
bag as poss ible, before installing the for­
ward-f acing chi ld restrain t.
- Always make sure that the safety be lt upper
anchorage is behind the ch ild rest raint and
not next to o r in fron t of the child rest raint
so th at the s afety be lt will be p roperly posi­
tioned.
- Always make sure th at there is noth ing on
the front passenger seat that will cause the
capacitive passenger detection system in
the seat to signal to the Airbag System that
the seat is occup ied by a person when it is
not, or to signal that it is occupied by some­
one who is heavier than the person actually
sitt ing on the seat . The presence of addi­
tional objects could cause the passenger
front airbag to be turned on when it should
be off, or could cause the airbag to work in a
way th at is differen t from the w ay it wou ld
have worked without the objec t on the seat .
- Ma ke sure th at the

whenever the ignition is switched on .
Advanced Airbag System components
The front passenger seat in your vehicle has a lot
of very important parts of the Advanced Airbag
System in it. These pa rts include the capacitive
passenger detection system, wir ing, brackets,
and more . T he control unit monitors the system
o n the front passenger seat when the ignit ion is
switched on a nd turns the airbag indicato r light
o n when a malfunction in the one of the system
components is
detected ¢ page 281. Because
t h e fron t passenger sea t contains impo rtan t
parts of the Advanced Ai rbag System , you must
take care to prevent it from being damaged .
Damage to the seat may prevent the Advanced
.,.

Airbag syste m
passenger detection system from accurately
measuring the capac itance of the ch ild safe­
ty seat and/or the person on the seat and
thus keep the Advanced Airbag System from
working properly .
- Never place or use any electrical device
(such as a laptop, CD player, electronic
games dev ice, power inverter or seat heater
for child seats) on the front passenger seat
if the device is connected to the 12-volt
socket or the cigarette lighter socket. S uch
devices can infl uence the capacitance reg is ­
tered by the capacitive passenger detection system, so that incorrect information is pro­
vided to the airbag control unit.
- If you must use a child restraint on the front
passenger seat and the child restraint man­
ufacturer 's instructions require the use of a
towel, foam cushion or something else to
properly position the ch ild restraint, make
certain that the
PASSENGER AIR BAG OFF
l ight comes on and stays on whenever the
child restraint is installed on the front pas­
senger se at.
- If the PASSENGER AIR BAG OFF light does
not come on and stay on, immedia tely in­
st al l child res traint in a rear seating posi tion
and have the airbag system inspected by
yo ur Audi dealer.
A WARNING
If the front passenger seat gets wet, dry it im­
mediately .
- If liquid soaks into the front passenger seat,
this can keep the airbag system from work­
ing properly and may, for instance, deact i­
vate the passenger frontal airbag. If this
happens, the
PASSENGER AIR BAG OFF
light will come on and stay on together with
the a irbag indicator light
m in the instru­
ment cluster.
- If liquid is poo led on the seat, but has not
soa ked in, this may also keep the airbag sys­
tem from wo rking properly and ca use the
passenge r frontal a irb ag to be enabled
(tu rned on), even though there is a properly
installed chi ld restraint system on the seat.
278
Wet towels or other wet things on the seat
cushion can have the same effect. If the
front passenger fronta l airbag is turned on,
the
PASSENGER AIR BAG OFF light will go
out .
How the Advanced Airbag System
components work together
The fro nt Advanced A irbag System and t he side
airbags supp lement t he protection offered by the
front t hree-point safety be lts and the adjustable
head restraints* to help red uce the risk of inj ury
i n a wide range of accident and crash sit uations.
Be sure to read the important information about
safety and heed the WARNINGS in this chapter.
Deployment of the Advanced Airbag System and
the activation of the safety belt pretensioners de ­
pend on the dece leration measured by the crash
sensors and registered by the electronic contro l
unit . Crash severity depends on speed and decel­
e ration as well as the mass and stiffness of the
vehicle or object involved in the crash.
On the passenger side, regardless of safety belt
use, the front passenger frontal a irbag will be
turned off if the electr ica l capacitance measured
by the capacitive passenge r detection system o n
t h e front passenger seat is less tha n the amount
prog rammed in t he elec tron ic cont ro l unit . The
front passenger frontal a irbag w ill also be turned
off if the capacitance measured by the system for
the front passenger seat equals that of an infant
of about one year of age in one of the chi ld seats
that was used to certify the Advanced Airbag Sys­
tem under Federa l Motor Vehicle Safety Standard
208 . The
PASSENGER AIR BAG OFF light comes
o n and stays on to tell you w hen the front Ad­
vanced Airbag Sys tem on t he passenger side has
been t urned

A WARNING
To reduce the ris k of injury when an airbag in­
flates, always wea r safe ty belts p rope rly.
- If you are un res tra ined, le a ning forwar d, si t­

More important things to know about front
airbags
F ig. 238 Inf lated fro nt a irbags
Safety belts are important to help keep front
seat occupants in the proper seated position so
that airbags can unfold prope rly and provide sup­
p lemental pro tection in a frontal collision.
The front airbags are designed to provide add i­
tional protect ion for the chest and face of the
d river and the front seat passenger when:
- safety belts are worn properly,
- the seats have been positioned so that the oc -
cupant is properly seated as far as possible
from the airbag,
- and for adjustable head restraints: the head re-
straints have been properly adjusted.
Because airbags inflate in the blink of an eye with
g reat fo rce, things you have on your lap or have
p laced on the seat cou ld become dangerous pro­
jectiles, and be pushed into you if the airbag in­
flates .
W hen an airbag deploys, fine dust is released.
This is normal and is not caused by a fire in the
veh icle. This dust is made up mostly of a powder
used to lubricate the airbags as they deploy . It
could irr itate skin .
It is important to remember that whi le the sup ­
p lemental a irbag system is designed to reduce
the likelihood of ser ious injuries, other injuries,
for example swel ling, bruising and minor abra -
Airbag system
sions, can also happen when airbags inflate . Air­
bags do not protect the arms or the lower parts
of the body. Front airbags supp lement the three ­
po int safety belts only in some frontal collisions
in which the vehicle dece leration is high enough
to dep loy the airbags .
Front airbags will not depl oy :
- if the ignition is switche d off when a crash oc-
curs,
- in side co llisions,
- in rear -end co llisions,
- in rollovers,
- when the crash decele ration measured by the
airbag system is less than the m inimum thresh­
old needed for airbag dep loymen t as registe red
by the electronic con trol un it.
The front passenger airbag also w ill not
deploy:
- when the fron t passenger seat is not occupied,
- when the e lectr ica l capacitance measured by
the capacit ive passenger detection system for
t he front passenge r seat ind icates that the pas­
senger side frontal airbag must be switched off
by the e lectronic control unit (the
PASSENGER
AIR BAG OFF
light c::> page 281 and how they
work comes on and stays on).
A WARNING
Sitting in the wrong position can increase the
risk of ser ious injury in crashes.
- To reduce the r isk o f injury when the airbags
inflate, the driver and passengers must al­
ways sit in an upright posit ion, m ust not
lean aga inst or place any part of their body
too close to the area where the airbags are located.
- Occupants who are unbelted, out of position
or too close to the airbag can be serio usly
i n jur ed by an airbag as it unfolds with g reat
for ce in the blink of an eye
