Important safety instructions about
safety belts
Safety belts must always be correctly posi­
tioned across the strongest bones of your
body.
~ Always wear safety belts as illustrated and
described in this chapter.
~ Make sure that your safety belts are always
ready for use and are not damaged.
A WARNING
Not wearing safety belts or wearing them
improperly increases the risk of serious
personal injury and death. Safety belts can
work only when used correctly.
- Always fasten your safety be lts correctly
before driving off and make sure all pas­
sengers are correctly restrained.
- For maximum protection, safety belts must always be positioned properly on
the body .
- Never strap more than one person, in­
cluding small children, into any belt.
- Never place a safety belt over a child sit­ ting on your lap.
- Always keep feet in the footwell in front
of the seat while the vehicle is being d riv­
en .
- Never let any person ride with their feet
on the instrument panel or sticking out
the window or on the seat.
- Never remove a safety belt while the ve­
hicle is moving. Doing so will increase
your risk of be ing injured or killed.
- Never wear belts twisted.
- Never wear belts over rigid or breakable
objects in or on your clothing, such as
eye glasses, pens, keys, etc., as these may cause injury.
- Never allow safety belts to become dam­
aged by being caught in door or seat
hardware .
- Do not wear the shoulder part of the belt
under your arm or otherwise out of posi ­
tion . Safety belts
139
- Several layers of heavy clothing may in­
terfere with correct positioning of belts and reduce the overall effectiveness of
the system .
- Always keep belt buckles free of anything
that may prevent the buckle from latch­
ing securely .
- Never use comfort clips or devices that
create slack in the shoulder belt . Howev­
er, special clips may be requ ired for the
proper use of some child restraint sys­
tems .
- Torn or frayed safety belts can tear, and
damaged belt hardware can break in an
accident. Inspect belts regularly.
If web­
bing , bindings, buckles, or retractors are
damaged, have belts replaced by an au­
thorized Audi dealer.
- Safety belts that have been worn and
loaded in an accident must be replaced
with the correct replacement safety belt
by an authorized Audi dealer. Replace­
ment may be necessary even if damage
cannot be clearly seen. Anchorages that
were loaded must also be inspected.
- Never remove, modify, disassemble, or
try to repair the safety belts you rs elf .
- Always keep the belts clean. Dirty belts
may not work properly and can impair
the function of the inertia reel¢

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 136.
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

-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 127.
-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

146 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 Requ ire­
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 167.
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 154, 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 167), 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 sitt ing 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 12 7, 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 155, 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 .

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
The airbag system can provide supplemental
protection to properly restrained front seat
occupants.
Fig. 153 L ocation of driver airbag: in steer ing wheel
Fig. 154 Locatio n of fro nt passenger's airbag: in the in ­
st rument panel
Your veh icle 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
¢ fig. 153 and the airbag for the front
passenger is in the instrument panel
¢ fig. 154 . 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
c h apters 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 your passengers, especially in­
fants and small children.
_&. WARNING
Never rely on airbags alone for protection.
- Even when they deploy, airbags provide
only supplemental protect ion.
-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
h icle is properly restrained.
_&. WARNING
-A pe rson on the front passenger seat, es-
pecially infants and sma ll 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 imposs ible in all conceiva­
ble situat ions that may happen during
the useful life of your vehicle.
- The Advanced Airbag System can deploy
in accordance with the "low risk" option
under the U.S. Federal Standard if a child
that is heavier than the typical one-year
old child is on the front passenger seat
and the other conditions for airbag de­
p loyment are met .

-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
A irbag system 149
seat in child rest raints that are listed in the
Standard
~ page 167, Child restraints and
Advanced Airbags.
"Supp ress ion" requires the fron t airbag on the
passenger side to be turned off if :
- a child up to about one year of age is re­
s trained on t he front passenger sea t in one
o f the rear -fac ing or fo rward -facing infan t
restraints listed in Federal Motor Vehicle
Safety Standard 208 with which the Ad­
vanced Airbag System in your ve hicle was
cert ified. For a listing of t he chi ld restraints
that were used to certify your veh icle's com­
plia nce w ith the US Safety Standard

-weight less than a thres hold level stored in
the control unit is detected on the front pas ­
senge r seat.
When a person is detected on the front pas­
senger seat, weighing more than t he total
weight of a chi ld that is about 1 year old re ­
stra ined in one of the rear-fac ing o r fo rward­
facing infant restraints (listed in Federal Mo­
tor Vehicle Safety S tanda rd 208 w it h whi ch

-a chi ld who has outgrown child restraints is
on the front passenger seat.
I f the front passenger airbag is turned off , the
PA SSENGER AIR BAG OFF light in the center
of the instrument panel wi ll come on and stay

The front ai rbag on the passenger side may
not deploy (the PASSENGER A IR BAG OFF
light does not illuminate and stay lit) if:
- a small ad ult or teenager is on the front pas­
senger seat
- a passenger who is not sitt ing upr ight w it h
their back against a non-reclined backrest
with their feet on the vehicle floo r in front
of the seat is on the front passenger seat .
I f the front passenge r airbag deploys, the
F ederal Standard requires the airbag to meet
the " low risk" deployment criteria to help re ­
duce the risk of injury through interact ion
with the airbag. " Low risk" deployment occurs
in those crashes that take place at lower de­
celerations as defined in the electronic control
un it .

Al way s remember: Even tho ugh your 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 impor­
tant information in the sect ions that follow
and be sure to heed a ll of the WARNINGS .
A WARNING
To reduce the ris k of injury whe n an airbag
inflates, a lways wear safety belts properly.
- If you are unrestrained, lean ing fo rward,
s itting sideways or out of position in any
way, your risk of in jury is much higher.
- You w ill also receive serio us inju ries 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 Advanced Airbag
q page 144.
A WARNING
A child in a rearward-fac ing ch ild 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
van ced A irbag System.
- Altho ugh the Advanced Airbag System in
your veh icle is designed to tur n
off the
front airbag when a rea rward-facing
chi ld 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 chi ld 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 exceptional c ircumstan­
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 ch ild
safety seat in a rear seating position and
have the airbag system inspected by your
authorized Audi dealer .
A WARNING
If, in exceptional 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 forward-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 adjustment range, as fa r away from
the airbag as possible, before installing

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 more. 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 contro 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.
- An Advanced Airbag with gas generator and
control valve for the driver inside the steer­
i ng wheel hub.
A irbag system 15 1
- An Advanced Ai rbag with gas gene rator and
contro l valve inside the instrument pane l for
the front passenger .
- A weight-sensing mat under the upholstery
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 electronic control unit to regu­
late deployment of the front Advanced Air­
bag on the passenger side.
- An airbag monitoring system and ind icator
light in the i nstr ument cluster ~

-A sensor in each front seat registers the dis­
tance betwee n the respective seat and the
steer ing whee l or inst rument panel. The i n­
formation register ed is sent cont inuous ly to
the ele ct ron ic cont ro l uni t to regulate de­
ployment o f the front Advanced A irbags .

forth;
- If a strap or tether is being used to tie the child safety seat to the front passenger
seat, make sure that it is not so tight that it
causes the we ight-sensing mat to measure
more weight than is actua lly on the seat.
If the PASSENGER AIR BAG OFF light still
does not come on
and does not stay on con­
tinuously (when the ignition is switched on),
- take the chi ld restraint off the front passen-

inspected by your authorized Audi dealer
immediately .
- move the ch ild to a rear seat pos it io n and
make sure that the child is properly restrain­
ed in a child restraint that is appropriate for
it s size and age. The
PASSENGER AIR BAG OFF light
should
NOT come on when the ignition is on and an
adult is s itting in a proper seating position on
the front passenger seat. If the
PASSENGER
AIR BAG OFF
light comes on and stays on or
flashes for about 5 seconds wh ile driving, un­
der these cir cumstances, make sure that:
- the adult on the front passenger seat is properly seated on the center of the seat
cushion with his or her back up aga inst the
backrest and the backrest is not recl ined
