Improperly worn safety belts
Incorrectly positioned safety belts can cause
severe injuries .
Wearing safety belts improperly can cause se­
rious injury or deat h. Safety belts can o nly
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 ncrea se t he risk of inju ry 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 a irbag dep loys and strikes an occu­
pant who is not in the correct seating posi ­
tion. A driver is respons ible for the safety of
all veh icle occupants and especially for chil­
dren . Therefore:
• Never perm it anyone to assume an incorrect
sitting position in the vehicle while traveling

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 act ivated by sen­
sors in front, side and rear-end collisions of
grea t severity. This tightens the belt and takes

up the slack helps to reduce forward occupant
movement dur ing a collision .
([) Note
Never let the belt remain over a rear seat­
back that has been folded forward.
@ 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
pretension er
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
Safety belts 145
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 .
_& 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 be lt system.
- Safety belt systems including safety belt
pretens ioners 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 author ized Audi dealer or qualified
technician who has an Audi approved re­
pair manual, training and special equip­
ment necessary.

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.
F or your safety and the safety of your passen­
gers, before driving off, always:
• Adjust the driver's seat and steering wheel
properly ¢
page 129,
• Adjust the front passenger's seat properly
¢ page 59,
• Wear safety be lts properly ¢ page 141,
• Always properly use the proper child re-
straint to protect children¢
page 167.
In a collision airbags must inflate within the
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 . Therefore in order to help the
a ir bag to do its job, it is important, both as a
d river and as a passenger to sit prope rly 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 ce rtain frontal collisions
¢page 129,
Proper occupant seating positions.
F or details
on the operation of the seat adjustment con­
t rols ¢
page 60.
It's especially important that children are
properly restrained ¢
page 167.
There is a lot that the driver and the passen­
ge rs can and must do to help the individual
safety features installed in your A udi 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 you have a physical impairment or con- dition that
prevents you from sitting properly
on the driver seat with the safety belt properly
fastened and reaching the pedals , spec ial
modifications to your vehicle may be necessa­
ry.
Contact your authorized Audi dea ler, or call
Audi C ustomer Re lations at 1-800-822-2834.
When the airbag system dep loys , a gas gener­
ator will f ill the airbags, break open the pad­
ded covers, and inflate between the steering
whee l and the dr iver 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
th rough 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 a irbags have deployed . The airbags also
inflate with a great deal of force and nothing
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
senger 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 a irbags w ill not inflate in all fronta l
collisions . The triggering of the airbag system
depends on the vehicle dece lerat ion 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 trigge red ,
even 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 veh icle 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 impact that will always trigger the
airbags, since the circumstances will vary con­
siderably between one collision and another.
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 also not inflate in
side or rear collisions, or in ro ll-overs .
Alwa ys rem ember : Airbags will deploy only
once, and only in certa in kinds of collisions .
Your safety belts are always there to offer pro­
tection in those s ituations in which airbags
are not supposed to deploy , or when they have
a lready deployed ; fo r example , when yo ur ve­
h icle strikes or is struck by another after the
first collision .
This is just one of the reasons why an a irbag is
a supplementary restra int and is not a s ubst i­
tute for a safety belt . The airbag system
works most effectively when used with the
safety belts. Therefore, always properly wear
your safety belts
¢ page 138.
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 co llision .
- Never sit closer than
10 inches (25 cm)
to the stee ring wheel or instrument pan­
el.
- If you cannot sit more than
10 i nches
(25 cm) from the steer ing whee l, investi­
gate whether adaptive equipment may
be available to help you reach the pedals
and increase your seating dis tance from
the steering wheel.
- If you are unrestrained, lean ing fo rward,
sitting sideways or out of position in any
way, yo ur risk of inj ury is much highe r.
- You w il l also receive serio us inju ries and
cou ld 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 isk o f injury when an air ­
bag inflates, a lways wear safety belts
proper ly ¢

Airbag system 147
-Always make certain that chi ld ren age 12
or younger a lways ride in the rear seat. If
children are not properly restrained, they may be severe ly inju red or killed when an
airbag inf lates .
- Never let ch ildren ride unrestra ined or
improperly restrained in the vehicle . Ad ­
just the front seats prope rly.
- Never ride with the backrest reclined.
- Always sit as far as possible from the
steer ing whee l or the instrument pane l
¢page 129.
-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 f loor in front of the seat to
he lp prevent serio us in juries to the legs
a nd h ips if the airbag inflates.
- Never recline the front passenger 's seat
to tra nsport objects. Items can a lso
move i nto the area of the s ide a irbag or
the front a irbag du ring bra king or in a
sud den maneuve r. Obje cts ne ar the air­
bags can become projectiles and cause
injury when an airbag inflates.
_&. WARNING ~
A irbags that have de ployed in a crash must
be replaced.
- Use on ly original equipment airbags ap­
proved by Audi and installed by a trai ned
technician who has the necessary too ls
and d iagnost ic equipment to properly re­
place any airbag in your vehicle and as­
sure system effectiveness in a crash .
- Never perm it salvaged or recycled air­
bags to be installed in your vehicle .

148 Airbag sys tem
Even tho ugh your vehicle is equip ped with an
Advanced Airbag System , make certain that
a ll c hildren, especially those 12 years and
younge r, a lways ride in the back seat properly
restra ined for their age and size. The airbag
on the passenger side makes the front seat a potentially dangerous place for a ch ild to r ide.
The front seat is not the safest place for a
child in a fo rward-facing ch ild safety seat. It
can be a very dangerous place for a n infant or
a child in a rea rward-facing seat.
The Advanced Airbag System i n your veh icle
has been certified to comp ly with the Requ ire­
men ts of Uni ted Sta tes Federa l Mo tor Veh icle
Safety Standard 208 as applicable at the time
your veh icle was manufactured.
The Standard requires the front a irbag on t he
passenger side to be turned off ("sup­
pressed") if a ch ild up to about one year of
age restrained in one of the rear -facing o r for­
ward -facing infant restraints listed i n Federal
Motor Vehicle Safety Standard 208 with which
the Advanced A irbag System in your vehicle
was certified has been installed o n the front
passenger seat . For a listing of the child re ­
strai nts t hat we re used to certify compliance
with the US Safety Standard
r=vpage 169.
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 BA G OFF
light will come on for a
few seconds a nd:
- will stay on if the front passenger seat is not
occupied,
- wi ll 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 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 requ ires the
fro nt 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
c hil d but less than the weight o f a small
adult, the front airbag on the passenger side
can deploy (the
PASSENGER AIR BAG OFF
li ght does not come on). If the PASSENGER
AIR BAG OFF
light does not come on , the
front a irbag on the passeng er side has not
been turned off by the elec troni c con trol unit
and can deploy if the control uni t se nses an
impact that meets the cond itions stored in its
memo ry .
For example, the airbag may deploy if:
- a small ch ild that is heav ier t han a typical 1
year-old ch ild is on the front passenger seat
( r egard less of whethe r the child is i n one of
t he child safety seats listed
r=v page 169), or
- a child who has outgrown ch ild restraints is
on t he front passenge r seat.
If the front passenger airbag is turned off, the
PASSENGER AIR BAG OFF light comes on in
the instr ument cluster and stays on.
The front airbag on the passenger s ide may
not deploy (the PASSENGER AIR BAG OFF
li gh t does not illum inate and stay lit) even if a
small adult o r teenager, or a passenger who is
not sitt ing up rig ht w ith their back against a
non- recl ined ba ck res t w it h thei r feet on the
vehicle f loor i n front of the sea t is on the front
passenger seat
r=v page 129 , Proper seating
position for the driver.
If t he fron t passenger a irbag dep loys, the
F ede ra l Standard req uires the airbag to meet
t h e "low risk" dep loyment criteria to red uce
t h e risk of injury t hrough interactio n wit h the
airbag. "Low risk" dep loyment occ urs in those
crashes that take place at lower dece lerat ions
as defined in the electronic control unit
r=v page 157, 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 fronta l
collision . T he a irbag could great ly reduce the
effectiveness of the ch ild restra int and even
seriously injure t he ch ild dur ing 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 167, 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 w ith 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 mus t inst all a rearward facing
child safety seat on the front passenger
seat beca use 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
sea t 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 149
aft ad justment 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
T o 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 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 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 effectiveness o r even
prevent them from providing any protec­
tion.
- An improper ly installed ch ild restra int
can interfere with the airbag as it de­
ploys and seriously i njure o r even kill the
child -even with an Advanced Airbag
System.
- Always carefu lly follow the manufact ur­
er 's ins tructions p rov ided with the ch ild
safety seat or carrier . •

Description of front airbags
The airbag system can provide supplemental
protection to properly restrained front seat
occupants.
F ig . 153 Location of driver airbag: in steer ing whee l
Fig. 15 4 Location of front passenger's airbag: in the in ­
strument panel
Your veh icle is equipped with an "Advanced
A irbag System" in compliance with United
States Federal Motor Vehicle Safety Standard ( FM VSS) 208 as app licab le at the time your
ve hicl e was manufac tured. The system senses
the position of the front seats and controls
front airbag inflation with a valve, 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 a re also activated
by the electron ic cont ro l unit for the ai rbag
system. T
he front safety belts also have load limiters
to help reduce the forces applied to the body
i n a crash .
T he airbag for the drive r is in the stee ring
whee l hub¢
fig. 153 and the airbag for the
front passenger is in the instrument panel
~ fig. 154 . The general locat ion of the a irbags
is marked "AIRBAG".
T here is a lot you need to know about the ai r­
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.
P lease be sure to heed the WARNINGS -they
are extremely importa nt for your safety and
the safety of your passengers, especially in­
fants and small chi ldren.
_&. WARNING
Neve r rely on airbags alone for p rotection.
- Even w hen they deploy, airbags provide
only s upplement al pro te ctio n.
- Airbag work most effect ive ly when used
