Airbag system
-An improperly 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 manufacture r'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 signa l that it is occupied by some­
one who is heav ier 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 vehicle was manufactured .
The airbag for the driver is in the steering wheel
hub
q fig. 153 and the airbag for the front pas­
senger is in the instrument panel
q fig. 154 . 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.
A 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 veh icle 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 dr iver's airbag inflates. ~

a co .... N
" N .... 0 00 \,;J ' -Never hold the steering wheel at the 12
o'clock position or with your hands any­
where inside the steering wheel or on the steering wheel hub . Holding the steering
wheel the wrong way increases the risk of severe injury to the arms, hands, and head if
the driver airbag deploys.
A WARNING
Objects between you and the airbag will in­
crease the risk of injury in a crash by interfer­
ing with the way the airbag unfolds 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 struck
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 personal injury.
- Never hold things in your hands or on your
lap when the vehicle is in use.
- Never place accessories or other objects
(such as cup holders, telephone brackets,
note pads, navigation systems, or things
that are large, heavy, or 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 place them between
these areas and you or any other person in
the vehicle.
- Never attach objects to the windshield
above the passenger front airbag, such as
accessory GPS navigation units or music
players. Such objects could cause serious 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 airbags or
the front airbag during breaking or in a sud­ den maneuver. Objects near the airbags can
fly dangerously through the passenger com­ partment and cause injury, particularly
when the seat is reclined and the airbags in­
flate.
Airbag system
A WARNING
r--
A person on the front passenger seat, espe-
cially infants and small children, will receive
serious injuries and can even be killed by be­ ing too close to the airbag when it inflates .
- Although the Advanced Airbag System in your vehicle is designed to turn off the front
passenger airbag if an infant or a small child
is on the front passenger seat, nobody can
absolutely guarantee that deployment un­
der these special conditions is impossible in
all conceivable situations that may happen
during the useful life of your vehicle.
- The Advanced Airbag System can deploy in accordance with the
.,low risk" option for 3-
and 6-year-old children under the U.S. Fed­
eral Standard if a child with electrical capac­ itance greater than the combined capaci­
tance of a typical one-year old infant re­
strained in one of the forward facing or rear­
ward-facing child seats with which your ve­ hicle was certified is on the front passenger
seat and the other conditions for airbag de-
ployment are met.
- Accident statistics have shown that children
are generally safer in the rear seat area than
in the front seating position.
- For their own safety, all children, especially
12 years and younger, should always ride in
the back properly restrained for their age
and size.
Advanced front airbag system
Your vehicle is equipped with a front Advanced
Airbag System in compliance with United States Federal Motor Vehicle Safety Standard 208, as
well as Canada Motor Vehicle Safety Standard (CMVSS) 208 as applicable at the time your vehi­
cle was manufactured.
The front Advanced Airbag System supplements
the safety belts to provide additional protection
for the driver's and front passenger's heads and
upper bodies in frontal crashes . The airbags in­
flate only in frontal impacts when the vehicle de-
celeration is high enough.

Airbag syste m
The front Advanced Airbag System for the front
seat occupants is not a substitute for your safety
be lts. Rather, it is part of the overa ll occupant re­
stra int system in your vehicle. Always remember
that the airbag system can on ly help to protect
you, if you are sitting upr ight, wearing your safe ­
ty belt and wearing it properly . This is why you
and your passengers must always be properly re­
stra ined, not just because the law requ ires you to
be.
The Advanced Airbag System in your veh icle has
been cert ified to meet the " low r isk" requ ire­
ments for 3 and 6 yea r-o ld children o n the pas­
senge r side and very sma ll adul ts on the d river
side . The low r isk dep loymen t cr iteria are intend ­
ed to he lp reduce t he risk of injury through inter­
action with the front airbag that can occur, for
examp le, by being too close to the steering wheel
and instrument panel when the airbag inflates .
I n addition, the system has been certified to
comp ly with the "suppression" requirements of
the Safety Standard, to turn off the front airbag
for infants 12 months old and younger who are
restrained on the front passenger seat in ch ild re­
stra ints that are listed in the Standard
c::> page 172, Child restraints and Advanced front
airbag system.
"Suppression" requ ires the front a irbag on the
passenger side to be turned off if:
- a chi ld up to about one year of age is restra ined
on the front passenger seat in one of the rear­
facing or forward-facing infant restraints listed
in Federal Motor Vehicle Safety Standard 208
with wh ich the Advanced Airbag System in your
vehicle was ce rt ified . For a listing of the ch ild
r estra ints tha t were used to certify your veh i­
cle's compl ian ce with the US Safety Standard
c::> page 172,
-When a person is detected on the fron t passen ­
ger seat th at has an electr ica l capacitance t hat
is mo re than the tota l electrical capac itance of
a chi ld that is about 1 year old restrained in one
of the rear -facing or forward-facing infant re­
straints (listed in Federal Motor Vehicle Safety Standard 208 with w hich the Advanced A irbag
System in your veh icle was certified) , the front
152 airbag on the passenger side may or may not
dep loy.
The
PASSENGER AIR BAG OFF lig ht comes o n
whe n the ele ct ronic control unit detec ts a t otal
e lectrica l capacitance on the front passenger seat
that requires the front airbag to be turned off. If
t h e
PASSENGER AIR BAG OFF light does not
come on, the front airbag on the passenger side
has not been turned off by the contro l unit and
can deploy if the contro l unit senses an impact
that meets the cond itions stored in its memory .
If the total e lectr ica l capacitance registered on
the front passenger seat is more than that of a
typ ica l 1 year-old, but less than the weight of a
small adult, the front a irbag on the passenger
s ide may deploy (the
PASSENGER AIR BAG OFF
li ght does not come on).
For e xample, th e airb ag may deploy if :
- a small ch ild that is heav ier than a typica l 1
year-old child is on the front passenger seat (regard less of whether the child is i n one of the
child seats listed
c::> page 172),
-a child who has outgrown c hild restraints is on
the front passenger seat .
If the front passenger airbag is turned off, the
PAS SENGER AIR BAG O FF light in the center of
the instrument panel will come on and stay on.
If the front passenger airbag dep loys, the Feder ­
al Standard requires the airbag to meet the "low
risk" dep loyment criteria to help reduce the r isk
of injury t hrough interaction with the airbag.
"Low risk" deployment occurs in those crashes
that take p lace at lower decelerations as defined
i n the elect ronic co ntrol unit
c::> page 158 .
Always remember : Even though your vehicle is
equipped with Advanced Airbags, the safest place
for ch ildre n is properly restra ined on the back
seat. Please be su re to read the impo rtant info r­
mation in the sect ions that fo llow and be sure to
heed all of the WARNINGS.

Airbag syste m
Airbag System for the front passenger seat from
doing its job in a crash.
The front Advanced Airbag S ystem con sists
of the follo wing :
-Crash sensors in the front of the vehicle that
measure vehicle acceleration/deceleration to
provide information to the Advanced Airbag
System about the severity of the crash.
- An electronic control unit, with integrated
crash sensors for front and side impacts. The
control unit "decides" whether to fire the front
airbags based on the information received from
the crash sensors . The control unit also "de ­
c ides" whether the safety belt pretens ioners
shou ld be activated .
- An Advanced Airbag with gas generator and
contro l valve for the driver ins ide the steer ing
whee l hub.
- An Advanced Airbag with gas generator and
contro l valve inside the instrument pane l for
the front passenger.
- A capacitive passenger detect io n system under­
neath t he front passenger seat cover. This sys­
tem measures the elect rical capac ita nce of the
person in the seat. The info rm ation registe red
is sent continuous ly to the e lectronic control
unit to regulate deployment of the front Ad ­
vanced Airbag on the passenger side .
- An airbag monitoring system and indicator
light in the instrument cluster
Q page 158 .
-A sensor in each front seat registers the dis ­
tance between the respective seat and the
steering wheel or instrument pane l. The infor ­

of the front Advanced Airbags .
- The
PASS ENGER AIR BA G OFF light comes on
and stays on in the center of the instrument

_&. WARNING
Damage to the front passenger seat can pre­
vent the front airbag from work ing properly.
- Improper repair or disassembly of the front
passenger and driver seat will prevent the
Advanced A irbag System from function ing
properly.
- Repairs to the front passenger seat must be
performed by qualified and properly trained
wo rkshop personne l.
- Never remove the front passenger or driver seat from the vehicle .
- Never remove the upholstery from the front
passenger seat.
- Never d isassemble or remove parts from the
seat or disconnect wires from it.
- Never carry sharp objects in your pockets or
put them on the seat. The capacit ive pas­
senger detect ion mat in the front passenger
seat will not function p roperly if it is punc­
tured.
- Never carry things on your lap or carry ob­
jects on the front passenger seat. Such ob­
jects can influence the capacitance regis­
tered by the capaci tive passenger detection
system, so that incorrect in format ion is pro­
vided to the airbag control unit.
- Never store i tems under the front passenger
seat. Parts of the Advanced Airbag System
under the passenger seat could be dam­
aged, p reventing them and the airbag sys­
tem from working p roper ly.
- Never p lace seat covers or replacement up­
holstery that have not been specifically ap­
proved by Audi on the front seats.
- Seat covers can prevent the Advanced Air­
bag System from recognizing child re­
straints or occupants on the front passenger
seat and prevent the side airbag in the seat
backrest from deploying properly.
- If a seat heater has been retrofitted or oth­
erwise added to the front passenger seat,
never install any child res tra int system on
this seat.
- Never use cushions, p illows, blankets, or
sim ila r items on the front passenge r seat.
The additional laye rs prevent the capac it ive

- Never place or use any electrical device
(suc h as a laptop, CD player, electronic
games dev ice, power inverte r or seat heater
for child seats) on the front passenger seat
if the devi ce is conne cted to the 12-volt
socket o r the cigarette lighter socket. Such
devices can in fluence the capacitance regis ­
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
passenge r seat and the child restraint man­
ufact urer 's instructions require the use of a
towel, foam cushion or something else to
properly pos ition the ch ild restraint, make
certain tha t the
PASSENGER AIR BAG OFF
ligh t comes on and stays on whenever the
c h ild restraint is installed on the front pas­
senger seat.
- If the PASSENGER AIR BAG OFF light does
not come on and st ay on, immedia tely in­
st all child res traint in a re a r se ating position
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 togethe r with
the a irbag indicator light
II (USA models)/
El (Canada models) in the instrument clus­
ter.
- If liquid is poo led on the seat, bu t has not
soa ked in, this may also keep the airbag sys­
tem from wo rking pro perly and ca use the
passenge r frontal airb ag to be enabled
(tu rned on), even though the re is a properly
Airbag syste m
installed child restraint system on the seat .
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 ligh t
will go out .

More important things to know about front
airbags
Fig. 155 In flated fro nt airba gs
Safety belts are important to help keep front
seat occupants in the proper seated position so
that airbags can unfold properly and provide sup­ plemental protection in a frontal collision.
The fron t airbags are designed to provide addi­
tional protection for the chest and face of the
driver 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
great force, things you have on your lap or have
placed on the seat could become dangerous pro­
jectiles, and be pushed into you if the airbag in­
flates .
When an airbag deploys, fine dust is released.
This is normal and is not caused by a fire in the
vehicle. This dust is made up mostly of a powder
used to lubricate the airbags as they deploy. It
could irritate skin.
It is important to remember that while the sup ­
plemental airbag system is designed to reduce
the likelihood of serious injuries, other injuries,
for example swelling, bruising and minor abra -
156
sions, can also happen when airbags inflate. Air ­
bags do not protect the arms or the lower parts
of the body . Front airbags supplement the three­
point safety belts only in some frontal collisions
in which the vehicle deceleration is high enough
to deploy the airbags .
Front airbags will not deploy :
-if the ignition is switched off when a crash oc-
curs,
-in side co llisions,
- in rear-end collisions,
- in rollovers,
- when the crash deceleration measured by the
airbag system is less than the minimum thresh­
old needed for airbag deployment as reg iste red
by the electron ic cont rol un it.
The front passenger airbag also will not
deploy:
- when the front passenger seat is not occupied,
- when the e lectrical capacitance measured by
the capacitive passenger detection system for
the front passenger seat indicat es that the pas­
senger side frontal a irbag must be switched off
by the electronic control unit (the
PASSENGER
AIR BAG OFF
light c::> page 158 and how they
work comes on and stays on).
A WARNING
, -
Sitting in the wrong position can increase the
risk of serious injury in crashes.
-To reduce the risk of injury when the airbags
inflate, the driver and passengers must al­
ways sit in an upright posit ion, must not
lean aga inst or place any part of their body
too close to the area where the airbags are
located.
- Occupants who are unbe lted, out of posit ion
or too close to the airbag can be serious ly
inju red by an airbag as it unfolds with g reat
force in the blink of an eye

Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag System
performs in a crash. For example, using tire-rim
comb inations not approved by Audi, lower ing the
vehicle, chang ing the stiffness of the suspension,
including the springs, suspension struts , shock
absorb ers etc . can change the forces that are
measured by the airbag sensors and sent to the
electronic control unit . Some suspension changes
can, for example, increase the force levels meas­
ured by the sensors and make the airbag system
deploy in crashes in which it would not deploy if
the changes had not been made. Other kinds of
162
changes may reduce the force levels measured by
the sensors and prevent the airbag from deploy­
i ng when it should .
& WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced Airbag performance and in­
crease the risk of serious personal injury in a
crash .
- Never install suspension components that do not have the same performance charac­
teristics as the components origina lly instal­
led on your vehicle.
- Never use tire-rim combinations that have
not been approved by Aud i.
