To prov ide max imum protection, safety belts
must always be positioned correctly on the wear ­
er's body .
"'Adjust the fro nt sea t and head restra int proper­
ly
¢ page 59 , Front seats .
"'Make su re the seatback of the rear sea t bench
is in an upright position and secure ly latched in
place before using the
belt ¢.&_ .
"'Pull the safety belt evenly across the chest and

"'Insert the tongue into the correct buckle of
you r seat until you hear it latch securely .
"' Pull on the belt to make sure that it is securely
l atched in the buck le.
Autom atic safety belt retractors
Every safety belt is equipped with an automatic
belt retractor on the shoulder belt . This feature
locks the belt when the belt is pulled out fast,
du ring hard braking and in an accident . The be lt
may a lso lock when you drive up or down a steep
h ill or th rough a sharp curve. Dur ing no rma l dr iv­
i n g the bel t lets you move freely.
Safety belt pretensioners
Safety belts w ith pretensioners help to tighten
the safety belt and remove slack when the pre­ tensioners a re
activated ¢ page 267. The func­
tion of the pretens ioner is moni to red by a w arn­
ing
light¢ page 26.

Convertible lock ing retractor
Eve ry safe ty belt except the one on t he d river
seat is equipped with a convertib le lock ing retrac ­
tor that
mu st be used when the safety be lt is
used to attach a ch ild seat. Be sure to read the
i mportant information about this feature
¢ page 305 .
A WARNING
Improperly positioned safety belts can cause
serious inj ury in an
accident ¢ page 265,
Safety belt position .
- Safety belts offer optimum protection only
when the seatback is up right and belts are
properly posit ioned on the body .
- Always make sure that the rear seat back ­
rest to which the center rear safety belt* is
at tached is securely latched whenever the
rear cen ter safety belt is being used.
If the
b ackrest is not sec urely latche d, the passen­
ger will move forward with the bac krest du r­
ing sudden b raking, in a sudden maneuver
and especia lly in a crash.
-Never attach the safety belt to the buckle
for another seat. Attaching the belt to the
wrong buckle will reduce safety be lt e ffec­
tiveness and can cause serio us personal in­
jury.
-A passenge r who is not properly restrained
can be seriously injured by the safety belt it­
self when it moves from the stronger parts
of the body into cri tical areas like the abdo­
men .
- Always lock the convertible locking retractor when yo u are securing a c hild seat in the ve­
h icle
~ page 307.

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 .

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. A lways remember
that the airbag system can on ly help to protect
you, if you are sitting upr ight, wear ing your safe­
ty belt and wear ing it properly . This is why you
and your passengers must always be prope rly re­
stra ined, not just beca use the law req uir es yo u to
be.
The Advanced Airbag System in your ve hicle has
been ce rt ified to meet the " low r isk" requ ire­
ments fo r 3 and 6 yea r-o ld children o n the pas­
senger side and very sma ll adul ts on the d rive r
side . The low r is k dep loymen t cr iteria are intend ­
ed to he lp reduce t he ris k of injury through inter­
action with the front airbag that can occ ur, for
examp le, by being too close to the steering whee l
and instrument pane l when the airbag inflates .
I n addition, the system has been certified to
comp ly with the "suppression" requirements of
the Safety Standard, to t urn off the front a irbag
for infants 12 months old and younger who are
restrained on the front passenger seat in c hild re­
stra ints that are listed in the Standard
<=:> page 297, Child restraints and Advanced front
airbag system.
"Suppress ion" requ ires the front a irbag on the
passenger side to be turned
off if:
- a ch ild up to about one year of age is restra ined
on the front passenger seat in one of the rear­
facing or forward-fac ing infant restra ints listed
in Federal Motor Vehicle Safety Standard 208
with wh ic h the Advanced Airbag System in your
vehicle was ce rt ified. For a listing of the c hild
r estra in ts tha t were used to certify your ve hi­
cl e's comp lian ce wi th t he US S afety St andard

- When a person is de te cte d on the fron t passen ­
ger sea t th at has an electr ica l capaci tance t hat
is mo re t han t he tota l electrical capac itance of
a chi ld that is about 1 year old restrained in one
of the rea r-facing or forward-facing infant re ­
straints (listed in Federal Motor Vehicle Safety Standard 208 w ith which the Advanced A irbag
System in your ve hicle was certified), the front
Airbag syste m
airbag on the passenger side may or may not
dep loy.
T he
PASSENGER AIR BAG OFF lig ht comes o n
whe n the elect ronic con trol uni t detec ts a t otal
electrica l capacitance on the front passenger seat
t h at 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 a n impact
t h at meets the cond it ions stored in its memory .
If the total electr ica l capacitance reg istered o n
the front passenger seat is more t han that of a
typ ical 1 year-old , but less than the weight of a
small ad ult, the front a irbag on the passenger
s ide may dep loy (the
PASSENGER AIR BAG OFF
li ght does not come on) .
For example, the airbag may deploy if :
-a small ch ild that is heav ier than a typ ica l 1
year-o ld child is on the front passenger seat
(regardless of whether the child is in one of the
child seats listed
¢ page 297),
- a child who has outgrown c hild rest raints is on
the front passenger seat.
If the front passenge r ai rbag is t urned off, the
PASSENGER AIR BAG OFF light in the center of
the instr ument pane l will come on and stay on.
If the front passenge r airbag deploys, the Feder ­
al Standard requi res t he airbag to meet the " low
risk" deployment criteria to he lp reduce the r is k
of i njury through interaction with the a irbag.
"Low risk" deployment occurs in those crashes
t h at take place at lower decelerations as defined
i n t he electron ic co ntro l
unit ¢ page 281 .
Always remember : Even though your vehicle is
equipped with Advanced Airbags, the safest place
for ch ildre n is properly restra ined o n the back
seat . Please be s ure to read the impo rtant in for­
mation in the sect ions that fo llow a nd be sure to
heed all of the WAR NIN GS.

Airbag syste m
-If you are unrestrained, leaning forward, sit­
t ing s ideways or out of pos ition in any way,
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
Airbag ¢ page 269.
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
PA SSEN­
GER AIR BAG OFF
light does not come on
and stay on, immediately insta ll the rear­
facing child seat in a rea r seating position
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
PASSENGER AIR BAG
OFF
li ght comes on and stays on all the time
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 System for the front passenger seat from
doing its job in a crash.
The front Ad vanced Airbag System con sists
o f th e follo wing :
-Cras h sensors in the front of the vehicle that
measure vehicle acceleration/deceleration to
provide information to the Advanced Airbag
System a bout the severity of the crash.
- An electronic control unit, with integrated
crash sensors for front and side impacts. The
contro l 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 for the
dr iver inside the steering wheel hub.
-An Advanced Airbag with gas generator ins ide
the instrument panel for the front passenger.
-A capac itive passenger detect io n system under­
neath the front passenger seat cover. This sys­

.&, WARNING ~ -
Damage to the front passenger seat can pre­
vent the front airbag from working properly.
-Improper repair or disassembly of the front
passenger and driver seat will p revent the
Advanced Airbag System from f unct ion ing
p roperly.
-Repairs to the front passenger seat must be
pe rformed by qualified and p roperly trained

-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 o r disconnect w ires from it.
-Never carry sharp objects in your pockets or
put them on the seat. The capacit ive pas­
senger de tect ion mat in the front passenger
seat will not function p roperly if i t is punc­
tured.
-Never carry things on your lap or carry ob­
jects on the front passenge r seat. S uch ob­
jects can influence the capacitance reg is­
tered by the cap aci tive passenger detection
sys tem, so that incorrect in formation is pro­
vided to the ai rbag control unit.
-Never store i tems unde r 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 wor king 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 chi ld re­
stra ints 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 ins tall any child restra int system on
this seat.
-Never use cushions, p illows , blankets, or
similar items on the front passenge r seat .
T he addi tional laye rs prevent the capacit ive

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
off ~ page 281 .
A WARNING
To reduce the ris k of injury when an airbag in­
flates, always wea r safe ty belts p rope rly.

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

A WARNING
A child in a rearward-facing child seat instal­
led o n the front passenger seat will be ser i­
ously injured and can be k ille d if the front air­
bag in flate s - even with an Advanced Airbag
System.
- The inflating a irbag w ill hit the child seat or
infant carrier w ith great force and will
smash the ch ild seat and child against the
backrest, cente r arm rest, door or roof.
- Always install rear-facing child seats on the
rea r seat.
- If you must install a rearward fac ing ch ild
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
your Audi dealer.
A WARNING
-
-
Objects between you and the a irbag w ill in­
crease the risk of in jury in a crash by interfer­
ing w ith the way the airbag unfolds or by be­
ing pushed into you as the a irbag inflates.
- Never hold th ings in your hands or on your
lap when the vehicle is in use .
- Never transport items on or in the area of
the fron t passenger seat . Objects could
move into the area of the front airbags du r­
ing bra king or other sudden maneuve rs and
become dangerous projec tiles that c an
ca use serious pe rsonal injury if the a irbags
inflate.
- Never pl ace or attach accessor ies or o ther
objects (such as cup ho lders, te lephone
brackets, large, heavy or bulky objects) on
the doors, over or nea r the area marked
"AIRBAG" on the steering wheel, instru­
ment pane l, seat backrests or between
those areas and yourself. These objects could cause injury in a crash, especially
when the airbags infla te.
- Never recline the front passenger's seat to
transport objects . Items can also move into
the a rea of the side airbag o r the front a ir-
280
bag du ring brak ing o r in a sudden maneu­
ver. Objects near the airbags can become pro jecti les and cause injury, part icularly
when the seat is reclined .
- Never p lace or transport objects on the
front passenger seat. Objects on the front passenger seat could cause the capacitive
sensor in the seat to signal to ai rbag system
that the seat is occ upied by a person when it
in fact is no t, or that the pe rson on the seat
is he avie r th an he or she act ually is. The
change in electric capacitan ce beca use of
such objects can cause the passenge r front
airbag to be turne d on when it should be
off, or can cause the airbag to work in a way
that is different from the way it would have
wo rked without objects on the seat.
- Always make sure that there is noth ing on
the front passenger seat that will cause the
capacitive passenger detection system in
the sea t 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 th an the person actu ally
si tting on the sea t. The presence of an o b­
ject could ca use the passenger front air bag
to be turned on when it should be off, or
could cause the airbag to work in a way that is diffe rent from the way it would have
worked without the object on the seat.
