114 Safety belts
-Failure to pay attention to the warning
light that come on, could lead to person­
al injury.
Why safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for
people riding in vehicles.
Fig. 121 Unb elted occupants in a ve hicle heading for a
wall
Fig. 122 Th e vehicle c rash es into the wall
The physical principles are simple. Both the
vehicle and the passengers possess energy
which varies w ith veh icle speed and body
weight . Engineers call this energy "kinetic en­
e rgy ."
T he higher the speed of the vehicle and the
greater the vehicle's weight, the more energy
that has to be "absorbed" in the crash .
Vehicle speed is the most significant factor.
If
the speed doubles from 15 to 30 mph (25 to
50 km/h), the energy increases 4 times!
Because the passengers of this vehicle are not
using safety belts
c::;, fig. 121, they will keep
moving at the same speed the vehicle was
mov ing just before the crash, until something
stops them - here, the wall ¢
fig. 122 .
The same principles apply to people sitting in
a vehicle that is involved in a frontal collision .
Even at city speeds of 20 to 30 mph (30 to 50
km/h), the forces acting on the body can
reach one ton (2,000 lbs. or 1,000 kg) or
more . At greater speeds, these forces are even
higher .
Peop le who do not use safety belts are also
not attached to their vehicle. In a frontal colli­
s ion they will also keep moving forward at the
speed their vehicle was travell ing just before
the crash . Of course, the laws of physics don't
just apply to frontal collisions, they determine
what happens in all kinds of accidents and col­
lisions .
What happens to occupants not wearing
safety belts?
In crashes unbelted occupants cannot stop
themselves from flying forward and being in­
jured or killed. Always wear your safety belts!

Automatic safety belt retractors
Every safety belt is equipped w ith an automat­
i c belt retractor on the shoulder be lt. This fea­
ture locks the be lt when the belt is pulled out
fast, dur ing hard braking and in an accident.
The belt may also lock when you drive up or
down a steep hill or through a sharp curve.
During normal driving the belt lets you move
freely.
Safety belt pretensioners
The safety belts are equipped with a belt pre­
tensioner that helps to tighten the safety belt
and remove slack when the pretensioner is ac­
tivated. The funct ion of the pretensioner is
monitored by a warning light
c::> page 16.
Sw itchable locking feature
E very safety belt except the one on the driver
seat is equipped with a switchable locking fea­
ture that
must be used when the safety belt is
used to attach a child safety seat. Be sure to read the important information about this
feature
c::> page 152.
A WARNING
Imprope rly positioned safety belts can
cause serious injury in an accident
o::> page 117, Safety belt position.
-Safety belts offer optimum protect ion
only when the seatback is upright and
Safety belts 11 7
belts are properly positioned on the
body.
- Always make sure that the rear seat
backrest to which the center rear safety
be lt is attached is securely latched when­
ever the rear center safety belt is being
used. If the backrest is not securely latched, the passenger w ill move for­
ward with the backrest during sudden
braking, in a sudden maneuver and espe­
cially in a crash .
- Never attach th e safety belt to the buck­
le for another seat . Atta ching the belt to
the wrong buckle will reduce safety be lt
effectiveness and can cause ser ious per­
sonal injury.
- A passenger who is not proper ly restrain ­
ed can be seriously injured by the safety
be lt itself when it moves from the stron­
ger parts of the body into critical areas
like the abdomen.
- Always lock the convertible locking re­
tractor when you are securing a child safety seat in the vehicle

124 Airbag system
Even though your vehicle is equipped with an
Advanced Airbag System, make certain that
all chi ldren, especially those 12 years and
younger, a lways ride in the back seat properly
restrained for their age and size. The airbag
on the passenger side makes the front seat a potentially dangerous place for a ch ild to ride.
The front seat is not the safest place for a
child in a forward-facing child safety seat. It
can be a very dangerous place for an infant or
a child in a rearward-facing seat.
The Advanced Airbag System in your veh icle
has been certified to comply with the require­
ments of United States Federal Motor Vehicle
Safety Standard 208 as applicable at the time
your vehicle was manufactured.
The Standard requires the front a irbag on the
passenger side to be turned off ("sup­
pressed") if a child up to about one year of
age restrained in one of the rear-facing or for­
ward -facing infant restraints listed in Federal
Motor Vehicle Safety Standard 208 with which
the Advanced Airbag System in your vehicle
was certified has been installed on the front passenger seat . For a listing of the child re ­
strai nts that we re used to certify compliance
with the US Safety Standard
r=v page 145.
The PASSENGER AIR BAG OFF light in the in­
strument panel te lls you when the front Ad­
vanced A irbag on the passenger side has been
turned off by the e lectronic control unit.
Each t ime you turn on the ignition, the
PAS ­
SENGER AIR BAG OFF
light will come on for a
few seconds and:
- will stay on if the front passenger seat is not
occupied,
- will stay on if there is a small child or child restraint on the front passenger seat,
- wi ll go off if the front passenger seat is oc ­
cupied by an adult as registered by the
weight-sensing mat
r=v page 133, Monitor­
ing the Advanced Airbag System .
The PASSENGER AIR BAG OFF light comes on
when the control un it detects a total weight
on the front passenger seat that requires the
front airbag to be turned off.
If the total weight on the front passenge r
seat is more than that of a typica l 1 year -old
chi ld but less than the weight of a small
adult, the front airbag on the passenger side
can deploy (the
PASSENGER AIR BAG OFF
light does not come on). If the PASSENGER
AIR BAG OFF
light does not come on, the
front airbag on the passenger side has not
been turned off by the electronic con trol unit
and can deploy if the control unit senses an
impact that meets the cond itions stored in its
memory .
For example, the airbag may deploy if:
-a small ch ild that is heav ier than a typical 1
year-old ch ild is on the front passenger seat
( re gard less of whether the child is in one of
the child safety seats listed
r=v page 145), or
- a child who has outgrown ch ild restraints is
on the front passenger seat.
If the front passenger airbag is turned off, the
PASSENGER AIR BAG OFF light comes on in
the instrument cluster and stays on.
The front airbag on the passenger s ide may
not deploy (the PASSENGER AIR BAG OFF
light does not illum inate and stay lit) even if a
small adult or teenager, or a passenger who is
not sitting upright with their back against a
non-reclined backrest with their feet on the
vehicle floor in front of the seat is on the front
passenger seat
r=v page 104, Proper seating
position for the driver.
If the front passenger airbag deploys, the
Federal Standard requires the airbag to meet
the "low risk" deployment criteria to reduce
the risk of injury t hroug h interaction with the
airbag. "Low risk" deployment occurs in those
crashes that take place at lower dece lerat ions
as defined in the electronic control unit
r=v page 133, PASSENGER AIR BAG OFF light .
Always remember, a child safety seat or infant
carr ier installed on the front seat may be
struck and knocked out of posit ion by the rap­
idly inflat ing passenger's airbag in a frontal
collision . The air bag could greatly reduce the
effectiveness of the ch ild restraint and even
seriously injure the child during inflation .

For this reason, and because the back seat is
the safest place for children - when properly restrained according to their age and size - we
strongly recommend that children always sit in the back seat
Q page 143, Child Safety.
A WARNING
-
A child in a rearward-facing child safety seat installed on the front passenger seat
w ill be seriously injured and can be k illed if
the front a irbag inflates - even with an Ad­
vanced Airbag System.
- T he inflating a irbag w ill hit the child
safety seat or infant carrier with great
force and w ill smash the ch ild safety sea t
and child against the backrest, cente r
armrest, door or roof .
- 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 because of exceptional circumstan­
ces and the
PASSENGER AIR BAG OFF
light does not come on and stay on , im­
med iately install the rear-facing child
safety seat in a rear seating posit ion and
have the a irbag system inspected by your
authorized Aud i dealer .
- Forward-fac ing ch ild safety seats instal­
led on the front passenger's seat may in­
terfe re with the deployment of the air­
bag and cause se rious personal injury to
the ch ild.
A WARNING
If, in exceptional c irc umstances, you mus t
install a forwa rd-facing child restra int on
the front passenger's seat:
- Alw ays make sure the forw ard-fac ing
seat has been des igned and certified by
its manufacturer for use on a front seat
with a passenger front and side airbag.
- Never put the forward -facing child re ­
straint up aga inst or very near the instru­
ment pane l.
- Always move the passenger seat into its
rearmost position in the seat's fore and
A irbag system 12 5
aft adjustment range, as far away from
the airbag as possible before installing
the forward-fac ing ch ild restraint. The
backrest must be adj usted to an upright
position .
- Make sure that the
PASSENGER AIR BAG
OFF
li ght comes on and stays on all the
time wheneve r the ignit ion is switched
on.
A WARNING
To reduce the risk of ser ious injury, make
su re that the
PASSENGER AIR BAG OFF
light w ill be displayed whenever a child re­
straint is installed on the front passenger
seat and the ignition is switched on.
- If the
PASSENGER AIR BAG OFF light
does not s tay on, per form the checks de ­
scribed
Q page 133, Monitoring the Ad ­
vanced Airbag System.
- Take the chi ld restraint off the front pas­
senger seat and install it properly at one
of the rear seat positions if the
PASSEN ­
GER AIR BAG Off light does not stay on.
- Have the airbag system inspected by
your author ized Audi dealer immed iate­
ly .
-Always carefu lly follow instr uctions from
child restraint manufacturers when in­
stall ing ch ild restra ints .
A WARNING
If, in except iona l circumstances, you must
install a forward or rearward-facing child
restra int on the front passenger's seat :
- Improper instal lation of ch ild restraints
can reduce their effect iveness o r even
prevent them from providing any protec­
tion.
- An improper ly installed ch ild restra int
can interfere with the a irbag as it de­
ploys and seriously i njure o r even kill the
child -even with an Adv ance d Airbag
System.
- Always carefu lly follow the manu factur­
er 's ins truc tions p rov ided with the ch ild
safety seat or car rier . •
•

-Accident statistics have shown that chil­
dren are generally safer in the rear seat
area than in the front seating posit ion.
- For their own safety, all children, espe­
cially 12 years and younger, sho uld al­
ways ride in the back properly restrained
for their age and size.
Advanced front airbag system
Your veh icle is equipped w ith a front Advanced
A irbag System in compliance with Un ited
States Federal Motor Vehicle Safety S tanda rd
208 as applicab le a t the time your vehicle was
manufac tured .
The front Advanced Airbag System supple­ ments the safety belts to provide add it iona l
p rotection fo r the driver's and fron t passeng­
e r' s heads and upper bodies in fronta l crashes.
The airbags inflate only in frontal impacts
when the vehicle dece leration is high enough .
The fron t Advanced A irbag Sys tem for the
front seat occ upants is no t a substi tute for
your safety bel ts. Rather, it is part of the over ­
a ll occupa nt restraint system in your vehicle.
A lways remember that the airbag system can
only help to protect you, if you are s itting up­
right, wearing your safety belt and wearing it
properly . This is w hy you and your passenge rs
must always be properly restrai ned, not just
because the law requires you to be .
The Advanced Airbag System i n your veh icle
has been certified to meet the " low r isk" re ­
qu irements for 3 and 6 year-o ld childre n on
the passenger s ide and very small adu lts on
the dr iver side. The low ris k dep loymen t cr ite­
ria are intended to he lp red uce the risk of i n­
j ury thro ugh in teraction with the front airbag
that can occ ur, fo r example, by being too
close to the steering whee l and instrument
panel when the airbag inflates.
I n addition, the sys tem has been certif ied 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 restra ined on the front passenger

"Supp ress ion" requi res the fron t airbag on t he
passenge r sid e to be turned off if:
- a child up to abo ut one year of age is re­
strained on the front passenger seat in one
of t he rear-fa cing o r fo rward -f a cing infan t
res traints listed in Federal Motor Vehicle
Safety Standard 208 with which the Ad ­
vanced Airbag System in your ve hicle was

weight of a chi ld that is about 1 year old re­
stra ined in one of the rear -fac ing or forward ­
facing infant restraints ( listed in Fede ral Mo­

Alwa ys remember: Even tho ugh you r vehicle
is equipped with Advanced Airbags, the safest
p lace for children is properly restrained on the
back seat. Please be sure to read the impo r­
tant information in the sect ions that follow
and be sure to heed a ll of the WARNINGS .
A WARNING
To reduce the risk of injury when an airbag
inflates, a lways wear safety belts prope rly .
- If you are unrestrained, lean ing forward,
sitting sideways or out of position in any
way, your risk of injury is much higher.
- You w ill also receive serio us in juries and
cou ld even be killed if you are up against
the a irbag or too close to it when it in­
fla tes - even with an Adv ance d Airbag
qpage 122.
A WARNING
A child in a rearward-fac ing ch ild safety
seat installed on the front passenger seat
will be serious ly injured and can be killed if
the front airbag inflates - even with an Ad­
van ced A irbag System.
- Altho ugh the Advanced Airbag System in
your veh icle is designed to tur n
off the
front air bag when a rearward-facing
child res traint has been instal le d on the
front passenger seat, nobody can abso ­
lutely g uarantee that dep loyment is im­
possible in all conceivable situations that
may happen dur ing the usefu l life of your
veh icle.
- The inflating airbag will h it the ch ild
safety seat or infant carrier with great
force and will smash the child safety seat
and child aga inst the backrest, center
armrest, doo r, or roof.
- Always install rearward-facing ch ild re­
straints in the back seat.
- If you must install a rearward fac ing
child safety seat on the front passenger
seat because of exceptiona l circumstan­
ces and t he
PASSENGER AIR BAG OFF
light does not come on and s tay on, im­
mediately inst all the rear-fac ing c hild

have the air bag system inspected by your
author ized Audi dealer .
A_ WARNING
If, in exceptiona l circumstances, you m ust
i nsta ll a forward-facing child restraint on
the front passenger's seat:
- Always make sure the forward-facing
seat has been designed and certified by its manufacturer for use on a front seat
with a passenger front and s ide a irbag .
- Never p ut the fo rward-facing child re­
straint up against or very near the instru­
ment panel.
- Always move the passenger seat into its
rearmost pos ition in the seat's fore and
aft ad justmen t range, as fa r away from
the airbag as possible, before ins talling

the forward-facing child restraint. The backrest must be adjusted to an upr ight
posit ion.
- Make sure that the

Advanced Airbag System components
The front passenger seat in your vehicle has a
l ot of very important parts of the Advanced
Airbag System in it. These parts include the
weight-sens ing ma t, sensors, wiring, brack­
ets, and mo re. The function of the system in
the front passenger seat is checked by the
e lectronic control unit when the ignition is on .
The control unit monitors the Advanced Air­ bag System and turns the airbag indicator
light on when a malfunction in the system
components is detected. The function of the
airbag ind icator light is described in greater
deta il below. Because the front passenger
seat contains impo rtant parts of the Ad­
vanced A irbag System, you m ust take care to
p revent it from being damaged. Damage to
the seat may prevent the Advanced Airbag for
the front passenger seat from doing its job in
a crash .
The front Advanc ed Airbag Syst em
con sis ts o f th e following :
-Crash sensors in the front of the vehicle that
measure vehicle acceleration/deceleration
to provide information to the Advanced Air­ bag System about the severity of the crash.
-An electronic control unit, with integrated
crash sensors for front and side impacts .
The cont ro l unit "decides" whether to fire
the front airbags based on the information r eceived from the c rash sensors. The control
unit a lso "dec ides" whet her the safety be lt
pretensione rs should be activated.

- A weight-sensing mat under the upho lstery
padding of the front passenger seat cushion
that measures the total weight on the seat .
The informat ion reg istered is sent continu­
ously to the electron ic control unit to regu­
late deployment of the front Advanced Air­
bag on the passenger side.

130 Airbag system
-Never carry sharp objects in your pockets
or place them on the seat. If the weight­
sensing mat in the passenger seat is
punctured it cannot work properly .
- Never carry things on your lap or carry
objects on the passenger seat. Such items can increase the weight registered
by the weight-sensing mat and send the
wrong information to the airbag control
unit.
- Never store items under the front pas­
senger seat. Parts of the Advanced Air­
bag System under the passenger seat
could be damaged, preventing them and
the airbag system from working proper­
ly.
- Never place seat covers or replacement
upholstery that have not been specifical­
ly approved by Audi on the front seats.
- Seat covers can prevent the Advanced Airbag System from recognizing child re­
straints or occupants on the front pas­
senger seat and prevent the side airbag
in the seat backrest from deploying prop­
erly .
- Never use cushions, pillows, blankets or
similar items on the front passenger
seat. The additional padding will prevent
the weight-sensing mat in the seat from
accurately registering the child restraint
or person on the seat and prevent the
Advanced Airbag System from function­
ing properly.
- If you must use a child restraint on the
front passenger seat and the child re­
straint manufacturer's instructions re­
quire the use of a towel, foam cushion or
something else to properly position the
child restraint, make certain that the
PASSENGER AIR BAG OFF light comes
on and stays on whenever the child re­
straint is installed on the front passen­ ger seat .
- If the
PASSENGER AIR BAG OFF light
does not come on and stay on, immedi­
ately install child restraint in a rear seat­
ing position and have the airbag system
inspected by your authorized Audi dealer.
How the Advanced Airbag System
components work together
The front Advanced Airbag System and the
side airbags supplement the protection of­
fered by the front three-point safety belts
with pretensioners and load limiters and the
adjustable head restraints to help reduce the
risk of injury in a wide range of accident and
crash situations. Be sure to read the impor­
tant information about safety and heed the
WARNINGS in this chapter.
Deployment of the Adva need Airbag System
and the activation of the safety belt preten­
sioners depend on the deceleration measured
by the crash sensors and registered by the
electronic control unit. Crash severity depends
on speed and deceleration as well as the mass
and stiffness of the vehicle or object involved
in the crash.
When the electronic control unit registers a
low severity crash and the safety belt is being
used , the airbag will not deploy. If the safety
belt is not being used, the first stage deploys,
followed by the second stage after a much lat­
er time in the crash sequence.
If the electronic control unit registers a crash
of medium severity, the first stage of the air­
bag deploys followed by the second stage at a
much later time in the crash sequence - re­
gardless of whether the safety belt is being
used or not . In higher severity crashes as reg ­
istered by the electronic control unit, both the
first and second stages deploy almost at the same time.
On the passenger side, regardless of safety
belt use, the airbag will be turned off if the
weight on the passenger seat is less than the
amount programmed in the electronic control
unit. The front airbag on the passenger side
will also be turned off if one of the child safe­
ty seats that has been certified under Federal
Motor Vehicle Safety Standard 208 has been
recognized on the seat. The
PASSENGER AIR
BAG OFF
light comes on and stays on to tell
you when the front Advanced Airbag on the passenger side has been turned off ..,_

A WARNING
To reduce the risk of injury when an airbag
inflates, always wear safety belts properly.
- If you are unrestrained, lean ing forward,
sitting sideways or out of position in any
way, your risk of injury is much higher.

cou ld even be killed if you are up against
the a irbag or too close to it when it in­
flates - even with an Advanced Airbag

More important things to know about
front airbags
F ig. 133 Inflated front a irbags
Safety belts are important to help keep front
seat occupants in the proper seated pos ition
so that airbags can unfold properly and pro­
vide supp lemental protection in a fronta l co l­
lision .
The front a irbags are designed to provide ad­
d itiona l protection for the chest and face of
the dr iver and the front seat passenger when :
- safety belts are worn properly,
- the seats have been positioned so that the occupant is properly seated as far as possi­
ble from the a irbag,
- and the head restraints have been proper ly
adjusted .
Because airbags i nflate in the blink of an eye
with great force, things you have on your lap or have placed on the seat could become dan­
gerous projectiles, and be pushed into you if
the airbag inflates.
A irba g sy stem 131
When an airbag deploys, fine dust is re leased.
This is norma l 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 whi le the
supplementa l airbag system is designed to re­
duce the like lihood of serious injuries, other
injur ies, for example swelling, bruising and
minor abras ions, can also happen when air­
bags i nflate. A irbags do not protect the arms
or the lower parts of the body . Front a irbags
supplement the th ree -po in t safety belts only
in some fronta l co llisions in which the vehicle
deceleration is high enough to deploy the air­
bags .
Front airbags will not deploy :
-if the ignition is sw itched off when a crash
o ccu rs,
- in side co llisions,
- in rear-end collisions,
- in rollovers,
- when the crash dece leration measured by
the airbag system is less than the minimum
threshold needed for a irbag deployment as
reg istered by the electron ic contro l unit .
The f ront pa ssen ger airbag als o will no t
deplo y:
- when the front passenger seat is not occu­
pied,
- when the weight on the front passenger
seat as sensed by the Advanced Airbag Sys­
tem ind icates that the front a irbag on the
passenger side has to be tu rned off by the
electronic contro l un it (the
PASSENGER AIR
BA G OFF
light comes on and stays o n).
.&, WARNING
Sitting in t he wrong pos ition can increase
the risk of serious injury in crashes.
- T o reduce the risk of injury when the air­
bags inflate, the driver and passenge rs
m ust always s it in an upright position,
m ust not lean against or place any part

132 Airbag system
of their body too close to the area where
the airbags are located.
- Occupants who are unbelted, out of posi­
tion or too close to the airbag can be se­ riously injured by an airbag as it unfolds
with great force in the blink of an eye
r=> page 123 .
A WARNING
A child in a rearward-facing child safety
seat installed on the front passenger seat
will be seriously injured and can be killed if
the front airbag inflates -even with an Ad ­
vanced Airbag System.
- The inflating airbag will hit the child
safety seat or infant carrier with great
force and will smash the child safety seat
and child against the backrest, center armrest, door or roof.
- 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 because of exceptional circumstan ·
ces and the
PASSENGER AIR BAG OFF
light does not come on and stay on, im­
mediately install the rear-facing child
safety seat in a rear seating position and
have the airbag system inspected by your
authorized Audi dealer .
A WARNING
Objects between you and the airbag will
increase the risk of injury in a crash by in­
terfering with the way the airbag unfolds
or by being pushed into you as the airbag
inflates.
- Never hold things in your hands or on
your lap when the vehicle is in use .
- Never transport items on or in the area
of the front passenger seat. Objects
could move into the area of the front air­
bags during braking or other sudden ma­
neuvers and become dangerous projec­
tiles that can cause serious personal in­
jury if the airbags inflate.
-
- Never place or attach accessories or oth­
er objects (such as cup holders, tele­
phone brackets, large, heavy or bulky ob­
jects) on the doors, over or near the area
marked "AIRBAG" on the steering wheel,
instrument panel, seat backrests or be­
tween those areas and yourself . These
objects could cause injury in a crash, es­
pecially when the airbags inflate.
- Never recline the front passenger's seat
to transport objects. Items can also
move into the area of the side airbag or
the front airbag during brak ing or in a
sudden maneuver. Objects near the air­
bags can become projectiles and cause
injury, particularly when the seat is re­
clined.
A WARNING
-T he fine dust created when airbags deploy
can cause breathing problems for people
with a history of asthma or other breath­
ing conditions.
= To reduce the risk of breathing problems ,
those with asthma or other respiratory
conditions should get fresh air right
away by getting out of the vehicle or
opening windows or doors.
- If you are in a collision in which airbags
deploy, wash your hands and face with
mild soap and water before eating.
- Be careful not to get the dust into your
eyes, or into any cuts or scratches.
- If the residue should get into your eyes ,
flush them with water.
