Safety belt preten­
sioners
How safety belt pretensioners work
In front, side ond rear-end collisions above a
particular severity and in o rollover, safety belts are tensioned automatically.
Reversible safety belt tensioners
The safety belts on the front seats are equip­
ped with power reversible tensioners . Th e fo l­
lowing functions are available when the driv­
er's/front passenger's safety belts are fas­
tened:
- Automatic tensioners: at the start of a drive,
the safety be lts automatically adjust to the
passenger after a certain time period or ve­
hicle speed.
- In certa in driving situations, the safety belts
may tighten with a reversible tensioning
f unction
~ page 94 .
- The safety belts may also tighten with this
reversible tensioning function in m inor colli­
sions.
Pyrotechnic safety belt pretensioners
The safety belts are equipped with safety be lt
p retensioners. The system is activated by sen ­
sors in front, side and rear -end collisions of
great severity and in a rollover. This tightens
the belt and takes up be lt slack ¢.&.

Taking up the s lack helps to reduce
forward occupant movement during a colli­
sion .
A WARNING
-It is possible for the pretensioners to de­
ploy incorrect ly .
- The pyrotechnic system can only provide protection for one collision .
If the pyro­
technic pretensioners dep loy, the preten­
sioning system must be replaced.
@ Tips
The pyrotechnic safety belt pretens ioners
can only deploy once . -
The safety belt p retensioners do not de ­
ploy in minor frontal and side collisions,
in rear-end co llisions, in rollovers and in
co llisions involving very little impact
force.
- A fine dust is released when the pyro­ technic safety belt pretensioners deploy.
This is normal and is not caused by a fire in the vehicle.
- The relevant safety requirements must
be observed when the vehicle or compo­
nents of the system are scrapped. A
qualified dealership is fam iliar with
these regulations and will be pleased to
pass on the information to you.
- Be sure to observe all safety, environ­
menta l and other regu lations if the veh i­
cle or individual parts of the system, par­
ticularly the safety belt or airbag, are to
be disposed. We recommend you have
your authorized Audi dealer perform this
service for you.
Service and disposal of safety belt
pretensioner
The safety belt pretens ioners are parts of the
safety belts on your Aud i. Installing, remov­
ing, servic ing or repairing of belt pretension­
ers can damage the safety belt system and
prevent it from working correctly in a co lli­
sion .
T he re a re some important things you have to
know to make su re that the effectiveness o f
the system wi ll not be impaired and that dis­
carded components do not cause injury or pol­
lu te the environment.
A WARNING
-Improper care, servic ing and repair proce-
dures can increase the risk of personal in­
jury and death by prevent ing a safety belt
pretensioner from activating when needed
or activating it unexpectedly:
- The belt pretensioner system can be act i­
vated only once. If belt pretensioners have been activated, the system must be
replaced.

Important things to know
Importance of wearing safety belts and
sitting properly
Airbags are only supplemental restraints. For
airbags to do their job , occupants must al­
ways properly wear their safety belts and be
in a proper seating position.
F or your safety and the safety of your passen­
gers, before driving off, a lways:
• Adjust the driver's seat and steering wheel
properly ¢
page 126,
• adjust the front passenger's seat properly
¢ page 57,
• Wear safety be lts properly ¢ page 138,
• Always properly use the proper child re-
stra int to protect children¢
page 170.
In a collision, airbags must inflate within the
blink of an eye and with considerable force .
The supplementa l airbags can cause injuries if
the dr iver or the front seat passenger is not
seated properly . Therefore in order to he lp the
a ir bag to do its job, it is important, both as a
d river and as a passenge r to sit prope rly at all
times.
By keeping room between your body and the
steering wheel and the front of the passenge r
compartment, the airbag ca n inflate fully and
comp letely and provide supp lemental protec­
tion in ce rtain frontal collisions¢

There is a lot that the driver and the passen­
gers can and must do to help the individua l
safety features installed in your A udi work to­
gether as a system.
P rope r seat ing pos ition is important so that
the front airbag on the drive r side can do its
job. If yo u have a physical impa irment or con- dition that prevents yo
u from sitting properly
o n the driver seat with the safety belt properly
fastened and reaching the pedals , or if you
have concerns with regard to the function or
operation of the Advanced Airbag System ,
please contact your author ized Audi dealer or
qualified workshop, o r call Audi Customer Re­
lations at 1-800-822-2834 fo r poss ible modi­
fica tions to your ve hicle.
When the airbag system deploys, a gas gener ­
ator will f il l the a irbags, break open t he pad­
ded cove rs, and inflate between the steering
whee l and the dr iver and between the instru­
ment pane l and the fron t passenger. The a ir­
bags will deflate immediately after dep loy­
ment so tha t the front occupants can see
t hr ough the windshie ld again witho ut inter­
ruption .
All of th is takes p lace in the b link o f an eye, so
fast that many peop le don't even realize tha t
the airbags have deployed. The airbags a lso
inflate with a great dea l of force and nothing
shou ld be in their w ay when they deploy.
Front a irbags in combination with properly
wor n safety belts slow down and lim it the oc ­
cupant's forward movement . T ogether they
help to prevent the drive r and front seat pas­
senger from hitting pa rts of the inside of t he
vehicle while reducing the forces acting on the
occupant dur ing the crash . In this way they
help to reduce the risk of injury to the head
and upper body in the crash. A irbags do not
protect the arms or the lower parts of the
body.
Both front airbags wi ll not inflate in all fronta l
collisions . The triggering of the airbag system
depends on the vehicle dece lerat ion rate
ca used by the co llision and registered by the
electron ic control unit. If th is rate is below
the reference value programmed into the con ­
t rol unit , the airbags will not be trigge red,

Child restraints on the front seat - some
important things to know
~ Be sure to read the important informat ion
and heed the WARNINGS for important de­
ta ils about ch ild ren and Advanced Airbags
Qpage 170.
Even though your vehicle is equ ipped with an
Advanced Airbag System, make certain that
all c hildren, 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 child to ride.
The front seat is not the safest place for a
child in a forward-facing child seat. It can be a
ve ry dangerous place for an infant or a ch ild 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 Veh icle
Safety Standard 208 as applicable at the time
your ve hicle was manufactured.
The Standard requires the front a irbag on the
passenger side to be turned off ("sup ­
p ressed") if a ch ild up to about one year of
age restra ined in one of the rear-facing o r fo r­
ward-facing infan t restra ints listed in Federal

Fo r exa mple, the a irbag may depl oy if:
-a small child that is heavier than a typical 1
year-o ld child is on the front passenger seat
(regardless of whether the child is in one of
the chi ld seats listed

- a ch ild who has outgrown child rest raints is
on the front passenger seat.
If the front passenger airbag is turned off, the

If the front passenger airbag deploys, the
Federal Standard requires the airbag to meet
the "low risk" deployment criter ia to reduce
the r isk of injury through interaction with the
airbag. "Low risk" deployment occurs in those
crashes that take place at lower decelerations
as defined in the electronic control unit
r::> page 15 7, PASSENGER AIR BAG OFF light.
Always remember, a chi ld seat or infant carri­
er insta lled on the front seat may be struck
and knocked out of position by the rapidly in­
flating passenger's airbag in a frontal colli­
sion. The airbag could greatly reduce the ef­
fectiveness of the child restraint and even se­
riously injure the child during inflat ion.
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
r::> page 170, Child Safety .
A WARNING
A child in a rearward-facing child seat in­
stalled on the front passenger seat will be
ser iously injured and can be killed if the
front airbag inflates -even with an Ad­
vanced Airbag System .
- T he inflating airbag will hit the child seat
or infant carrier with great force and wi ll
smash the child seat and child against
the backrest, center armrest, door or roof.
- Always install rear-facing child seats on
the rear seat.

system inspected by your A udi dealer.
- Forward-facing child seats installed on the front passenger's seat may interfere
with the dep loyment of the a irbag and
cause serious persona l injury to the
child.
A WARNING
If, in except iona l circumstances, you must
install a forward -facing child restraint on
the front passenger's seat:
- Always ma ke s ure 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 put the forward-facing child re­
straint up against or very near the instru ­
ment panel.
- Always move the passenge r seat into its
rea rmost pos ition in the seat's fore and
aft ad justment range, as far away from
the airbag as possible before installing
the forward-fac ing ch ild restra int. The
backrest must be adjusted to an upright
position.
- Make sure that the

-Take the child 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 Audi dealer immediately.
- Always carefully follow instructions from
child restraint manufacturers when in­
stalling child restraints .
A WARNING ,.
If, in exceptional circumstances, you must
install a forward or rearward-facing child
restraint on the front passenger's seat:
- Improper installation of child restraints
can reduce their effectiveness or even
prevent them from providing any protec­
tion.
- An improperly installed child restraint
can interfere with the airbag as it de­
ploys and seriously injure or even kill the
child -even with an Advanced Airbag
System.
- Always carefully follow the manufactur­
er's instructions provided with the child
safety seat or carrier.
- Always make sure that there is nothing
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 occupied by a person when it is not, or to signal that it
is occupied by someone who is heavier
than the person actually sitting on the
seat. The presence of additional 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 occupants .
Fig. 129 Loc atio n of drive r ai rb a g : i n steering wheel
Fig. 130 Loc atio n of fro nt passe nge r's airbag: in the in­
st rumen t panel
Your vehicle is equipped with an "Advanced
Airbag System" in compliance with United
States Federal Motor Vehicle Safety Standard
(FMVSS) 208 as applicable at the time your
vehicle was manufactured . The safety belts
for the seats have "pretensioners" that help to take slack out of the belt system. The pre­
tensioners are also activated by the electronic control unit for the airbag system.
The front safety belts also have load limiters to help reduce the forces applied to the body
in a crash.
The airbag for the driver is in the steering
wheel hub
c:> fig. 129 and the airbag for the
front passenger is in the instrument panel
c::;, fig. 130. The general location of the airbags
is marked "AIRBAG".
There is a lot you need to know about the air­
bags 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 ex tremely important for your safety and
the safety of your passengers, especially in ­
fants 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 ve ­
hicle 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 positions to help reduce the risk
of personal injury if the driver's airbag in­
flates.
- 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
increase the risk of injury in a crash by in­
terfering with the way the airbag unfolds
and/or by being pushed into you as the air­
bag inflates.
- Always make sure nothing is in the front
airbag 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
deploys and cause serious personal in­
jury.
- Never hold things in your hands or on
your lap when the vehicle is in use .
-
Airbag system 149
-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 windshield; never place them over or
near or attach them to the area marked
,,AIRBAG " on the steering wheel, instru­
ment 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 mu­
sic players. Such objects could cause seri­
ous injury in a collision, especially when
the airbags inflate.
- Never recline the front passenger seat to transport objects. Items can also move
into the deployment area of the side air ­
bags or the front airbag during breaking
or in a sudden maneuver . Objects near
the airbags can fly dangerously through
the passenger compartment and cause
injury, particularly when the seat is re­
clined and the airbags inflate.
A WARNING
-=
A person on the front passenger seat , es-
pecially infants and small children, will re­
ceive serious injuries and can even be kil­
led by being 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 under these special conditions is impossible in all conceiva­
ble situations that may happen during
the useful life of your vehicle.
- The Advanced Airbag System can deploy
in accordance with the ,,low risk" option
