Safety belts 143
Improperly worn safety belts
I ncorrectly positioned safety belts can cause
severe injuries .
Wearing safety belts improperly can cause se­
rious injury or death. Safety belts can only
work when they are correctly positioned on
the body . Improper seat ing pos itions reduce
the effectiveness of safety be lts and will even
i ncrease the risk of injury and death by mov­
ing the safety be lt to crit ica l areas o f the
body. Improper seating positions also in ­
crease the risk of serious injury and death
when an airbag dep loys and strikes an occu­
pant who is not in the correct seating posi­
tion. A driver is responsible for the safety of
all vehicle occupants and especially for ch il­
dren . Therefore:
.. Never permit anyone to assume an incorrect
sitt ing position in the vehicle while traveling
¢ &,. .
A WARNING
Improperly worn safety belts increase the
risk of serious persona l injury and death
whenever a ve hicle is being used.
- Always make s ure that all vehicle occu­
pa nts are co rrectly restrained and stay in
a co rrec t seating position whenever the
veh icle is being used .
- Always read and heed al l WARNINGS a nd

Safety belt preten­
sioners
How safety belt pretensioners work
In front , side and rear -end collisions above a
particular severity, safety belts are tensioned automatically.
The safety belts are equipped with safety belt
pretensioners . The system is activated by sen­
sors in front, side and rear-end co llisions of
great seve rity . This tightens the belt and takes
u p belt slack¢.&.
in Service and disposal of Iii>

144 Safety belts
safety belt pretensianer on page 144. Taking
up the slack helps to reduce forward occupant
movement during a collision.
{[) Note
Never let the belt remain over a rear seat­
back that has been folded forward.
(D Tips
The safety belt pretensioner can only be activated once.
- In minor frontal and side collisions, in
rear-end collisions, in a rollover and in
accidents involving very little impact
force, the safety belt pretensioner are
not activated.
- In the case of a side crash, the safety
belt pretensioners will activate on the
driver's or front passenger's sides only,
depending on which side of the vehicle
the crash occurs .
- When the safety belt pretensioners are
activated, a fine dust is released. 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 . An au­
thorized Audi dealer or qualified work­
shop is familiar with these regulations
and will be pleased to pass on the infor­
mation to you.
- Be sure to observe all safety, environ­
mental and other regulations if the vehi­
cle or individual parts of the system, par­
ticularly the safety belt or airbag, are to
be disposed. We recommend you have
your authori zed Audi dealer perform this
service for you .
Service and disposal of safety belt
pretensioner
The safety belt pretensioners are parts of the
safety belts on your Audi . Installing, remov­
ing, servicing or repairing of belt pretension­
ers can damage the safety belt system and prevent it from working correctly
in a colli­
sion.
There are some important things you have to
know to make sure that the effectiveness of
the system will not be impaired and that dis­
carded components do not cause injury or pol­
lute the environment.
A WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal in­
jury and death by preventing a safety belt
pretensioner from activating when needed
or activating it unexpectedly :
- The belt pretensioner system can be acti ­
vated only once . If belt pretensioners
have been activated, the system must be
replaced.
- Never repair, adjust, or change any parts
of the safety belt system.
- Safety belt systems including safety belt
pretensioners cannot be repaired. Spe­
cial procedures are required for removal,
installation and disposal of this system.
- For any work on the safety belt system,
we strongly recommend that you see
your authorized Audi dealer or qualified
technician who has an Audi approved re­
pair manual, training and special equip­
ment necessary.
@ For the sake of the environment
Undeployed airbag modules and preten­
sioners might be classified as Perchlorate
Material -special handling may apply, see
www .dtsc.ca.gov/hazardouswaste/per­
chlorate. When the vehicle or parts of the restraint system including airbag modules
safety belts with pretensioners are scrap­ ped, all applicable laws and regulations
must be observed . Your authorized Audi
dealer is familiar with these requirements
and we recommend that you have your
dealer perform this service for you.

Airbag system 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.
For your safety and the safety of your passen­
gers, before driving off, always:
"" Adjust the driver's seat and steering wheel
properly ¢
page 128,
"" Adjust the front passenger's seat properly
¢page 59,
"" Wear safety be lts properly ¢ page 140,
"" Always properly use the proper child re-
straint to protect chi ldren ¢
page 166.
In a collision airbags must inflate within th e
blink of an eye and with considerable force.
The supplemental airbags can cause injuries if
the driver or the front seat passenger is not
seated properly . Th erefore in order to help the
a ir bag to do its job, it is important, both as a
driver and as a passenger to s it 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
comp letely and provide supplemental protec­
tion in certain frontal collisions ¢

Proper occupant seating positions.

trols ¢
page 60.
It's especially important that children a re
properly restrained ¢
page 166.
There is a lot that the driver and the passen­
gers can and must do to help the individual
safety features installed in your Aud i work to­
gether as a system.
Proper seating pos ition is important so that
the front airbag on the driver side can do its
job. If yo u have a physical impa irment or con-
Airbag system 145
dition that prevents you from sitting properly
on the driver seat with the safety belt properly
fastened and reach ing the peda ls, spec ial
modifications to your vehicle may be necessa­
ry.
Contact your authorized Audi dea ler, or call
Audi Customer Re lations at 1-800-822-2834.
When the airbag system dep loys, a gas gener­
ator will fi ll the airbags, break open the pad ­
ded covers, and inflate between the steering
whee l and the driver and between the instru­
ment panel and the front passenger. The air­
bags will deflate immediately after deploy­
ment so that the front occupants can see
through the windshield aga in without inter­
ruption .
All of th is takes place in the blink of an eye, so
fast that many people don 't even realize that
the air bags have deployed . The airbags also
inflate with a great deal of force and noth ing
shou ld be in their way when they deploy.
Front airbags in combination with properly
worn safety belts slow down and limit the oc ­
cupant's forward movement. Together they
help to prevent the driver and front seat pas­
senge r from hitting parts of the inside the ve­
hicle 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 air bags w ill not inflate in all frontal
collisions . The triggering of the air bag system
depends on the vehicle deceleration rate
caused by the collision and registered by the
electron ic control unit.
If this rate is below
the reference value programmed into the con­
trol unit, the airbags will not be triggered,
ev en though the car may be bad ly damaged as
a resu lt of the co llision . Vehicle damage, re­
pair costs or even the lack of ve hicle damage
is no t necessarily an indication of whether an
airbag should inflate or not .
It is not possib le to define a range of vehicle
speeds that w ill cover every possib le kind and ..,.

angle of im pact that will always trig ger the
airbags, since the circumstances wi ll vary con­
siderably between one collision and another.
Important factors include, for example, the
nature (hard or s oft) of the object which the
car h its, the angle of impact, vehicle speed,
etc. The front airbags will also not inflate in
side or re ar collisions, or in roll-overs .
Always remember : Airbags will deploy only
once, and only in certa in kinds of collisions .
Your safety belts are always there to offe r pro­
tection in those s ituations in which airbags
a re not supposed to deploy , or when they have
a lready deployed; for example , when yo ur ve­
h icle strikes or is st ruck by another after the
first collision .
This is just one of the reaso ns why an a irbag is
a supplementary restra int and is not a s ubst i­
tute for a safety be lt. The airbag system
works most effective ly when used with the
safety be lts. Therefore, always properly wear
you r safety belts ¢
page 137 .
A WARNING
Sitting too close to the steer ing wheel or
instrument panel will decrease the effec­
tiveness of the airbags and will increase
the risk of pe rsonal injury in a collision .
- Never sit closer than 10 inches (25 cm)
to the stee ring wheel or instr ument pan­
el.
- If you cannot sit more than 10 inches
(25 cm) from t he steer ing wheel, investi­
gate whethe r adaptive equipment may
be available to help you reach the pedals
and incre ase your sea ting dis tance from
the steering wheel.
- If you are unrestr ained, lean ing fo rward,
s itting sideways or out of posi tion in any
way, your risk of injury is much higher.
- Yo u w il l a lso receive serio us in juries and
co uld even be killed if you are up against
the airbag or too close to it when it in ­
flates -even with an Advanced Airbag.
- To reduce the r is k of i njury when an air ­
bag inf lates, a lways wear safety belts
properly
c::> page 140, Safety belts .
-Always make certain that ch ild ren age 12
or younger always ride in the rear seat. If
children are not properly restrained, they
may be severe ly injured or killed when an
airbag inflates .
- Never let c hildren ride unrestrained or
improperly restrained in the vehicle . Ad­
just the front seats prope rly .
- Never ride with the back rest reclined.
- Always sit as far as possible from the
steer ing whee l or the instrument pane l
¢page 128.
-Always sit upright with 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
he lp prevent serious in ju ries to the legs
and h ips if the airbag inflates .
- Never recline the front passenger 's seat
to transport objects . Items can a lso
move i nto the a rea of the s ide airbag or
the front a irbag d uring br akin g or in a
sudden maneuve r. Obje cts ne ar the air ­
bags can become projec tiles and cause
inj ury when an airbag inflates.
.&, WARNING
A irbags that have deployed in a crash must
be replaced.
- Use on ly original eq uipment airbags ap ­
proved by Audi and installed by a trained
technician who has the necessary too ls
and d iagnost ic equipment to properly re­
p lace any airbag in your vehicle and as­
sure system effectiveness i n a crash .
- Never permit salvaged or recycled air­
bags to be installed in your vehicle .
Child restraints on the front seat - some
important things to know
.,. Be su re to read t he importa nt information
and head the WAR NINGS for important de­
t ails about children and Advanced A irbags
c::> page 166. ..,.

Even though your vehicle is equipped with an
Advanced Airbag System, make certain that
all ch ildren, 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 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 w ith the Requ ire­
ments of United States Federa l Motor Vehicle
Safety Standard 208 as applicable at the time
your vehicle was manufactured.
The Standard requires the front ai rbag on the
passenger side to be turned off ("sup­
p ressed") if a ch ild 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 wh ich
the Advanced Airbag System in your vehicle
was certified has been installed on the front passenger seat . For a listing of the child re­
straints that were used to certify compliance
with the US Safety Standard
Qpage 168.
The PASSENGER AIR BAG OFF light in the in­
strument panel tells you when the front Ad­
vanced A irbag on the passenger side has bee n
turned off by the electronic 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,
- will go off if the front passenger seat is oc­
cupied by an adult as registered by the
weight-sensing mat
Q page 156, 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.
Airbag system 147
If the total weight on the front passenger
seat is more than that of a typical 1 year-o ld
c hild 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 a irbag on the passenger side has not
been turned off by the electronic con trol unit
and can deploy if the contr ol 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 ie r than a typical 1
year-old ch ild is o n the front passenger seat
(regard less of whether the child is in one of
the child safety seats listed
Q page 168), or
- a child who has outgrown child 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 side 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 uprig ht with their back against a
non-reclined backrest w ith their feet on the
vehicle floor in front of the seat is on the front
passenger seat~
page 128, 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 thro ugh interaction with the
airbag . "Low risk" deployment occ urs in those
crashes that take place at lower dece lerat ions
as defined in the electronic control unit
Q page 156, 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 inflating passenger's airbag in a frontal
collision . The airbag could greatly reduce the
effectiveness of the child restraint and even
seriously injure the child during inflation. •

148 Airbag sys tem
For this reason, and because t he bac k seat is
the safest place for children - when prop erly
restra ined according to their age and size - we
strongly recommend that children always sit in the back seat
Q page 166, 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
t he front a irbag inflates - even wit h an Ad­
v a nced Airb ag System.
- T he inflating a irbag will hit the child
safety seat or infant carrier with g reat
force and w ill smash the ch ild safety sea t
and child against the backrest, center
armrest, door or roof .
- Always install rear-facing child safety
seats on the rear seat .
-If you mus t inst all a rearwar d fa cing
child safety seat on the front passenger
seat because of exceptional circ umstan­
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 position and
have the a irbag system inspected by you r
au thorized Audi dealer .
- Forward-fac ing ch ild safety seats instal ­
led on the front passenger's seat may in­
terfer e wi th the deployment of the air­
bag and cause se rious personal injury to
the ch ild.
A WARNING
If, in exceptional c ircumstances, you mus t
install a forwa rd-facing child restra int on
the front passenger's seat:
- Always m ake su re the forw ard-fa cing
sea t has been des igned and certified by
its manufact urer for use on a front seat
with a passenger front and side airbag.
- Never put the forward -facing child re ­
st raint up aga inst or very near the inst ru­
ment pane l.
- Always move the passenger seat into its
rearmost position in the seat's fore and aft ad
justment range, as fa r away from
the airbag as possible before installing
the forward-fac ing ch ild restra int. The
backrest must be ad justed 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 serious inju ry, ma ke
sure that the
PASSENGER AIR BAG OFF
lig ht w ill be displayed whenever a child re­
straint is insta lled on the front passenger
seat and the ignition is switched on .
- If the
PASSENGER AIR BAG OFF light
does not stay on, per form the checks de ­
scribed ¢
page 156, 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 carefully follow instr uctions from
child restraint manufacture rs when in­
stalling ch ild restra ints.
A WARNING
-If, in except iona l circumstances, you must
i nstall a forward or rearwa rd -facing child
r estra int on t he front passenger's seat :
- Improper installation of ch ild restra ints
can reduce their effectiveness o r even
p revent them from providing any protec­
tion.
- An improperly installed ch il d restra int
can inter fere with the airbag as it de­
p loys and seriously injure o r even kill the
child -even with an Advance d Airbag
System.
- Always caref ully follow the m anu factur ­
er 's ins truc tio ns p rov ided with the ch ild
safety sea t or carrier .

-Never place additional items on the seat
that can increase the total weight regis­
tered by the weight-sensing mat and can
cause injury in a crash.
Front airbags
Description of front airbags

Your veh icle is equipped w ith an "Advanced
Ai rbag System" in compliance with United
States Federal Motor Vehicle Safety Standard (F MVSS) 208 as app licab le at the time your
ve hicle w as manufac tured. The system senses
the position of the front seats and controls
front airbag inflation with a va lve, depending
on the distance between the respect ive seat
and the steering wheel or instrument panel.
The safety belts for the seats have "preten­
sioners" that he lp to take slack out of the belt
system . The pretensioners are also activated
by the electron ic contro l unit for the airbag
sys tem.

The front sa fety 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 stee ring

is marked "AIRBAG".
There is a lot you need to know about the ai r­
bags in your vehicle . We urge you to read t he
detailed information about airbags, safety
belts and child safety i n this and the other
chapters that make up the owner's literature. Please be sure to heed the WARNINGS -they
are extremely important for your safety and
the safety of yo ur passengers, especially in­
fants and small children.
_&. WARNING
N ever rely on airbags alone for protec tion.
- E ven w hen they deploy, airbags provide
only s uppleme nta l pro tect ion .
- Airbag work most effective ly when used
wit h properly wor n safety belts.
- Therefore, always wea r you r safe ty belts
and make sure that eve rybody i n your ve­
hicle is p rope rly res trained.
_&. WARNING
A pe rson on the fron t passe nger seat, es­
pe cial ly infants and sma ll children, will re­
ceive serious injuries and can even be kil­ l ed by being too close to the airbag when
it inflates .
- Altho ugh the Advanced Airbag System in
your veh icle is designed to tur n off the

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 applicable at the time your vehicle was
manufactured.
The front Advanced Airbag System supple­ ments the safety belts to provide additional
protection for the driver's and front passeng­
er's heads and upper bodies in frontal crashes .
The airbags inflate only in frontal impacts
when the vehicle deceleration is high enough.
The front Advanced Airbag System for the
front seat occupants is not a substitute for
your safety belts. Rather, it is part of the over­
all occupant restraint system in your vehicle.
Always remember that the airbag system can
only help to protect you , if you are sitting up­
right, wearing your safety 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 vehicle has been certified to meet the "low risk" re ­
quirements for 3 and 6 year-old children on
the passenger side and very small adults on
the driver side . The low risk deployment crite­
ria are intended to help reduce the risk of in­
jury through interaction with the front airbag
that can occur, for example , by being too
close to the steering wheel and instrument panel when the airbag inflates.
In addition, the system has been certified to
comply with the "suppression" requirements of the Safety Standard
, to turn
off the front
airbag for infants 12 months old and younger
who are restrained on the front passenger
seat in child restraints that are listed in the
Standard ¢
page 168, Child restraints and
Advanced Airbags .
"Suppression" requires the front airbag on the
passenger side to be turned
off if:
- a child up to about one year of age is re­
strained on the front passenger seat in one
of the rear-facing or forward-facing infant restraints listed in Federal Motor Vehicle
Safety Standard 208 with which the Ad­
vanced Airbag System in your vehicle was
certified . For a listing of the child restraints
that were used to certify your vehicle's com­ pliance with the US Safety Standard
¢page 168,
-weight less than a threshold level stored in
the control unit is detected on the front pas­
senger seat.
When a person is detected on the front pas­
senger seat, weighing more than the total
weight of a child that is about 1 year old re­
strained in one of the rear-facing or forward­
facing infant restraints (listed in Federal Mo­
tor Vehicle Safety Standard 208 with which
the Advanced Airbag System in your vehicle
was certified), the front airbag on the passen­ ger side may or may not deploy.
The
PASSENGER AIR BAG OFF light comes on
when the electronic control unit detects a to­
tal weight on the front passenger seat that re­
quires the front airbag to be turned
off. 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 control
unit and can deploy if the control unit senses
an impact that meets the conditions stored in
its memory.
If the total weight on the front passenger
seat is more than that of a typical 1 year-old ,
but less than the weight of a small adult, the
front airbag on the passenger side may deploy
(the
PASSENGER AIR BAG OFF light does not
come on).
