Safety belts
Why use safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for peo
ple riding in vehicles .
Fig. 144 Unbelted occupants in a veh icle headi ng fo r a wall
Fig. 145 T he vehicle c rashes into the wall
The physical principles are simple. Both the vehi
cle and the passengers possess energy which var ies w ith vehicle speed and body weight . Engi
neers call this energy "k inetic energy."
The 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 us
ing safety belts~
fig. 144, they will keep moving
at the same speed the vehicle was moving just
before the crash, unti l something stops them -
here, the wall~
fig. 145.
The same principles apply to people sitting in a
vehicle that is involved in a frontal collision . Even
at c ity speeds of 20 to 30 mph (30 to 50 km/h),
the forces acting on the body can reach one ton
128
(2,000 lbs, or 1,000 kg) or more . At greater
speeds, these forces are even higher.
People who do not use safety belts are also not
attached to their vehicle. In a frontal collision
they will also keep moving forward at the speed
their vehicle was travelling 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 collisions .
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!

Unbelted occupants a re not able to res ist the tre
mendous forces of impact by holding tight or
bracing themselves. Without the benefit of safe
ty restraint systems, the unrestra ined occupant
will slam violently into the steering wheel, in
strument pane l, windshield, or whatever e lse is
in the way ~
fig. 146. T his impact with the vehi
cle interior has all the energy they had just be-
fore the crash.

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
9 page 119,
.,. Adjust the front passenger's seat properly
9 page 53,
.,. Wear safety belts properly 9 page 129 ,
.,. Always properly use the proper child restraint
to protect children
9 page 159.
In a collision, airbags must inflate within the
blink of an eye and with considerable force. The
supplemental airbags can cause injuries if the
driv er or th e front s eat passenger is not seat ed
properly. Therefore in order to help the airbag to
do its job, it is important, both as a driver and as
a passenger to si t 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 pro tection
in certain frontal collisions
o page 119, Correct
passenger seating positions .
For details on the
operation of the seat adjustment controls
o page 53.
It's especially important that children are proper
ly restrained
9page 159.
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 th e 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 mov e
ment . Togethe r they help to prevent the drive r
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 s ide or rear collisions, or in
ro ll-overs.
Alwa ys rememb er: 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
dep loy, or when they have already deployed ; for
examp le, when your vehicle str ikes or is struck by
another vehicle after the first coll is ion.
This is just one of the reasons why an airbag is a
supp lementary 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 127 .
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 10 inches (25 cm) to
the steering wheel or instrument panel.
- If you cannot si t mo re than 10 inches
(25 cm) from the steering wheel, invest i
gate whether adaptive equipment may be
available to help you 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 inflating airbag .
-If you are unrestrained, leaning fo rward, s it
t ing s ideways or out of 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
airbag or too close to it when it inflates -
even with an Advanced Airbag.
136
-
- To reduce the risk of injury when an airbag
inflates, always wear safety belts properly
r=;, page 130, Safety belts.
- Always make certa in that children age 12 or
younger 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 ride unrestra ined or im
properly restrained in the vehicle. Ad just the
front seats properly.
- Never ride with the backrest recl ined .
- Always sit as far as possible from the steer-
ing wheel or the instrument panel
r=;, page 119.
-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 a irbag or the front air
bag du ring brak ing o r in a sudden maneu
ver. Objects nea r the airbags can become
projecti les and cause injury when an airbag
inflates.
A WARNING
Airbags that have deployed in a crash must 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 your vehicle and assure system
effectiveness in a crash .
- Never perm it salvaged or recycled airbags to
be installed in your vehicle.
Child restraints on the front seat - some
important things to know
.,. Be s ure to read the impo rtant info rmat ion and
heed the WARN INGS for important details .,.
-Always make sure that there is nothing on
the front passenger seat that will ca use 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 heavier than the person actua lly
sitting on the seat. The p resence of addi
tional objects could cause the passenger
front airbag to be turned on when it shou ld
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.

The front safety belts also have load limiters to
help reduce the forces applied to the body in a
crash.
T he airbag for the drive r is in the steering wheel

general locat ion of the airbags is marked "AIR
BAG".
There is a lot you need to know about the airbags i n your vehicle . We urge you to read the deta iled
information about airbags, safety be lts and ch ild
safety in this and the other chapters that make
up the ow ner's literature . Please be sure to heed
the WARNINGS - they are extremely important
for yo ur safety and the safety of your passengers,
especially infan ts and small children.
_&. WARNING
-
Neve r rely o n ai rbags alone fo r prote ct ion.
- E ven w hen they deploy, airbags provide only
supp lemental pro tection.
- Ai rbag work most effectively when used
with p roperly worn safety belts.
- Therefo re, always wear your safety belts and
make sure that everybody in your ve hicle is
p roperly restrained.
- Always hold the steering w heel with both
ha nds on the outside of the steering wheel
rim at the 9:00 o'clock and 3 :00 o'clock po
sitions to help reduce t he risk of personal i n
jury if the driver's a irbag inflates.
- Never hold the stee ring wheel at the 12
o'clock position or wi th your hands any
where inside the steering wheel o r on the
steer ing whee l hub . Holding the steering
wheel the wrong way increases the r isk of
severe injury to the arms, hands, and head if
the dr iver airbag deploys.

Airbag system
& 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.
& WARNING
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
140
-
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 deployment 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.
The front Advanced Airbag System for the front
seat occupants is not a substitute for your safety belts. Rathe r, it is part of the overall occupant re
straint system in your vehicle . Always remember
that the airbag system can only help to protect
you, if you are sitting upright, wearing your safe
ty belt and wearing it properly . This is why you
and your passengers must always be properly .,.
restrained, not just because the law requires you
to be.
The Advanced Airbag System in your ve hicle has
been certified to meet the " low r isk" require
ments for 3 and 6 yea r-o ld children on the pas
senger side and very sma ll adults on the driver
side . The low r isk dep loyment cr iteria are intend
ed to help reduce the risk of injury through inter
action with the front a irbag that can occur, for
examp le, by being too close to the steering wheel
and instrument panel when the airbag inflates .
In addition, the system has been certified to
comply w ith the "suppression" requirements of
the Safety Standard, to turn off the front a irbag
for infants 12 months old and younger who are
restrained on the front passenger seat in child re
stra ints that a re listed in the Standard
¢ page 161, Child restraints and Advanced front
airbag system .
"Suppression" 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 fro nt passenger seat i n one of the rear
facing or forward-fac ing infant restra ints listed
in Federal Motor Vehicle Safety Standard 208
with wh ich the Advanced Airbag System in your
vehicle was certified . For a listing of the ch ild
restraints that were used to certify your vehi
cle's compliance with the US Safety Standard
¢ page 161,
-When a person is detected on the front passen
ger seat that has an electrical capacitance that
is more than the tota l electrical capac itance of
a ch ild that is about 1 year old restra ined in one
of the rear-facing or forward-facing infant re
straints (listed in Federal Motor Veh icle Safety
Standard 208 w ith which the Advanced A irbag
System i n your veh icle was certified), the front
airbag o n the passenge r side may o r may not
deploy.
The
P A SSENGER AIR B AG OFF light comes on
when the electron ic cont rol un it detects a total
e lectrical capacitan ce on the front passenge r seat
that requ ires the front a irbag to be turned off. If
the
PAS SENGER AIR BAG OFF light does not
come on, the front airbag on the passenger side
Airb ag sys tem
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 capaci tance reg istered on
the front passenger seat is mo re than that of a
typica 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
PA SS ENGER AIR BA G OFF
light does not come on).
For example , the ai rbag ma y deplo y if:
- a small ch ild that is heav ier than a typ ica l 1
yea r-o ld child is on the front passenger seat
(regardless o f whether the child is in one of the
child seats listed
¢ page 161),
-a child who has outgrown c hild restraints is on
the front passenge r seat .
If the front passenge r a irbag is t urned off, the
PASSENGER AIR BAG OFF light in the center of
the instrument pane l wi ll come on and stay on .
If the front passenger a ir bag deploys, the Feder
al Standa rd requi res the ai rbag to meet the "low
risk" deployment criteri a to he lp redu ce the r isk
of inj ury th rough interaction with the airbag .
" Low risk" deployment occurs in those crashes
that take p lace at lower decelerations as defined
in the electronic contro l unit ¢
page 146.
Alwa ys remember : Even though your vehicle is
equipped with Advanced Airbags, the safest place
for children is properly restrained on the back
seat. Please be sure to read the important infor
mation in the sections that fo llow and be sure to
heed all of the WARNINGS.
A WARNING
To reduce the risk of injury when an airbag in
flates, always wea r safety belts properly.
- If you are u nrestra ined, leaning forward, sit
ting sideways or out of position in any way,
your r is k of injury is much highe r.
- You will also receive ser ious injuries and
could even be killed if yo u are up against the
ai rbag or too close to it when it inflates -

the front Advanced Airbag on the passenger side has been turned off.
- A sensor in the safety belt latch for the driver
and for the front seat passenger that senses
whether that safety belt is latched or not and
transmits this information to the electronic control unit.
A 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 prevent the
Advanced Airbag System from functioning properly.
- Repairs to the front passenger seat must be
performed by qualified and properly trained
workshop personnel.
- Never remove the front passenger or driver
seat from the vehicle.
- Never remove the upholstery from the front
passenger seat.
- Never disassemble or remove parts from the
seat or disconnect wires from it.
Airbag system
-Never carry sharp objects in your pockets or
put them on the seat. The capacitive pas
senger detection mat in the front passenger
seat will not function properly 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 capacitive passenger detection
system, so that incorrect information is pro
vided to the airbag control unit.
- Never store items under the front passenger
seat. Parts of the Advanced Airbag System
under the passenger seat could be dam
aged, preventing them and the airbag sys
tem from working properly.
- Never place 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 restraint system on
this seat.
- Never use cushions, pillows, blankets, or
similar items on the front passenger seat.
The additional layers prevent the capacitive
passenger detection system from accurately
measuring the capacitance of the child 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 device, 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. Such
devices can influence the capacitance regis
tered by the capacitive passenger detection
system, so that incorrect information is pro
vided to the airbag control unit.

A WARNING
Objects between you and the airbag will in
cr ease the risk of inju ry in a cras h by interfer
ing w ith the way the airbag unfol ds 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 front 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 projectiles that can
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 o r bulky objects) on
the doors, over or near 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 inflate.
- Never recline the front passenger's seat to transport objec ts. Items can also move into
t h e a rea of the side airbag o r the front a ir
bag during braking or in a s udden maneu
ver. Objects near the airbags can become
projectiles and cause in ju ry, particularly
when the seat is reclined.
- Never pl ace or transport o bje cts on the
front passenge r seat . Objects on the front
passenge r seat co uld cause the capac itive
sensor in the seat to signal to airbag system
that the seat is occupied by a person when it
in fact is not, or that the person on the seat
is heavier than he or she actually is. The
change in elect ric capac itance because of
s u ch objects can cause the passenger front
airbag to be turned on when it shou ld be
off, or ca n cause the a irbag to wo rk i n a way
that is diffe rent from the way it would have
wor ked witho ut objects on the seat.
- Alway s m ake sure th at the re is nothing on
t h e fron t passenger seat that w ill cause the
capacit ive passenger detection system in
the seat to signa l to the Airbag System that
146
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 an ob
ject could ca use 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 diffe rent from the w ay it would have
wo rked withou t the object on the seat.
A WARNING
-
The fine dus t created when airbags deploy c an
cause breathing prob lems for peo ple with a
h istory of asthma or othe r breath ing cond i
tions.
- To reduce the r is k of breathing p roblems,
those with asthma o r other respiratory con
ditions shou ld get fresh a ir right away by
getting out of the vehicle or opening win
dows or doors .
- If you are in a co llision in which airbags de
ploy, wash yo ur hands and face with m ild
soap and water before eating.
- Be ca refu l not to get the dust into your eyes,
or into any cuts or scratches.
- If the residue sho uld get into your eyes,
