Safety belts
General notes
Always wear safety belts!
Wearing safety belts correctly saves lives!
This chapter explains why safety belts are necessary, how
they work and how to adjust and wear them correctly.
- Read all the information that follows and heed all of the
instructions and WARNINGS.
& WARNING
Not wearing safety belts or wearing them improperly increases
the risk of serious personal injury and death.
• Safety belts are the single most effective means available to
reduce the risk of serious injury and death in automobile acci­
dents. For your protection and that of your passengers, always
correctly wear safety belts when the vehicle is moving.
• Pregnant women, injured, or physically impaired persons must
also use safety belts. Like all vehicle occupants, they are more
likely to be seriously injured if they do not wear safety belts. The
best way to protect a fetus is to protect the mother -throughout
the entire pregnancy. •
Number of seats
Your Audi has a total of four seating positions: two in the front and
two in the rear. Each seating position has a safety belt.
& WARNING
Not wearing safety belts or wearing them improperly increases
the risk of serious personal injury and death.
• Never strap more than one person, including small children,
into any belt. It is especially dangerous to place a safety belt over
a child sitting on your lap.
• Never let more people ride in the vehicle than there are safety
belts available.
• Be sure everyone riding in the vehicle is properly restrained
with a separate safety belt or child restraint. •
Safety belt warning light~
Your vehicle has a warning system for the driver and (on
USA models only) front seat passenger to remind you
about the importance of buckling-up.
Before driving off, always:

- Fasten your safety belt and make sure you are wearing it
properly . ._

-Make sure that your passengers also buck le up and prop ­
erly wear the ir safety belts .
- Protect your children with a child restraint system appro-
priat e for the si ze and age of the child ren.
The warn ing light tin the instrument cluster lights up when the igni­
tion is switched on as a reminder to fasten the safety belts. In addi­
tion, you wi ll hear a war ning sound.
After the ignition is switched on, the warning tone will come on for abou t 6 seconds along with a t warn ing light in the inst rument
cluster if e ither the driver or (on USA models o nly) front seat
passenge r has not fastened their safety bel t. As soon as the driver
and front seat passenger have fastened the safety belt, the warning
tone will stop and the warning light will go out.
If both the driver and front seat passenger have not buckled- up
within about 24 seconds after the warning tone has stopped, the
wa rning tone w ill sound aga in for about 6 seconds. The warn ing tone
w ill sound repeatedly for about 6 seconds at 24 second interva ls unt il
bo th the driver and fron t passenger have bu ckled -up. The safety belt
warning system is active for about 5 minutes and during this time the
warning light in the instrument cluster wi ll stay on.
Fasten your safety b elt now and make sure that your pa ssengers
also properly put on their safety belt s. •

Why safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for people
riding in vehicles .

h ea din g for a wall
Fig . 18 8 T he veh icle
cr ash es into t he wall
Th e physical pr incip les are simple. Bot h the vehicle and the passen­
gers possess energy which varies with vehicle speed and body weight.
Enginee rs call th is energy "kine tic en ergy ."
The higher the speed of the vehicle and the greater the veh icle's
weight, the more energy that has to be "absorbed" in the crash .
Vehicle speed is the most significant factor.
If the speed doub les
from 15 to 30 mph (25 to SO km/h), the energy increases 4 times!

Child restraints on the front seat - some
important things to know
- Be sure to read the important information and head the WARNINGS for important detai ls about children and
Advanced Airbags =:>
page 22 2.
Even though your veh icle is eq uipped with an Advanced Airbag
System, make certain that all ch ildren, especially those 12 years and
younger, a lways r ide in the back seat properly rest rained for the ir age
and size . The airbag on the passenger side makes the front seat a
poten tially dangerous place fo r a child to r ide. The front seat is not
the safest place for a child in a forward-facing c hild safety seat. It can
be a ve ry dange rous place fo r an infant or a child in a rearward-fac ing
seat.
T he Advanced Airbag System in your vehicle has been cert ified to
comply with the Req uirements of United States Federa l Moto r
Vehicle Safety Standard 208 as applicable at the time your vehicle
was ma nufactu red .
The Standard requires the front airbag on the passenger side to be tu rned off ("supp ressed") if a c hild up to abo ut one year o f age
restra ined in one of the rear -facing or forward -fac ing infant
restrain ts listed in Federa l Moto r Vehicle Safety Sta ndard 208 with
w hich the Advanced Airbag System in your veh icle was certified has
been installed on the front passenger seat. For a listing of the chi ld
restra ints that were used to cert ify complia nce w ith the US Safety
Standard
=> page 224.
T he PASSENGER AIR BAG OFF ligh t in t he inst rumen t panel tells you
when the front Advanced Airbag on the passenger s ide has been
tu rn ed off by the electronic con tro l u nit.
Eac h time you turn on the ign ition, the
PASSENGER AIR BAG OFF
light will come on for a few seconds and:
• will stay on if th e fron t passenger seat is no t occupied, •
will stay on if there is a small ch ild or child restra int on the front
p assenge r seat,
• will go off if the front passenger seat is occup ied by an adult as
reg iste red by the weight-sens ing mat =:>
page 211, "Monitori ng the
Adva nced Airbag System" .
Th e
PASSENGER AIR BAG OFF light comes on when the control unit
detects a tota l we ight on the front passenger seat t hat req uires the
front airbag to be t urned off.
If the tota l we ight on the front passenger sea t is more than th at of a
typical 1 year-old child but less than the weight of a small adu lt, the
front airbag on t he p assenger s ide c an dep loy (the
PASSENGER AIR
BAG OFF
li g ht 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 tu rned off by the e lectron ic control u nit and can deploy if
the contro l unit senses an impact that meets the conditions stored in
its memory.
For e xample , the a irbag may deploy if:
• a small chi ld that is heavier than a typical 1 year -old child is on the
front passenge r seat (regardless of whether the child is in one of the
child safety seats listed =>
page 224), or
• a chi ld who has outgrown ch ild restra ints is on the front passenger
seat.
If the front passenger a irbag is turned off, the
PASSENGER AIR BAG
OFF
light comes on in the instrument cluster an d stays o n.
Th e front airbag on the passenger side may
not dep loy (t he
PASSENGER AIR BAG OFF light does not illum inate and stay lit) even
if a small adult or teenage r, or a passenger who is no t si tting upright
w ith the ir back against a non-recli ned backrest w it h their feet on the
vehicle floor in front of the seat is on the front passenger seat
=:>
page 178, " P rope r seat ing pos ition for the dr ive r" .
If the front passenger airbag deploys, the Federal Standard requ ires
th e airb ag to meet the "low risk" deployment criteria to red uce the
r is k of injury through interaction with the airbag. "Low risk" deploy­
ment occurs in those crashes t hat ta ke place a t lower decelerations as .,.

Always remember , a c hild safety seat or infa nt ca rr ie r i nstalled on th e
front seat may be str uck and k noc ked out of position by the ra pidly
in flating p assenge r's ai rbag in a frontal coll is io n. T he a irbag could
great ly reduce the effect iveness of the c hild restraint and even seri ­
o us ly i njur e the chi ld dur ing inflation.
For this reason, and because t he back seat is the safest place for chil­
dren -whe n properly restrained according to their age an d size -we
st rong ly recommend t hat childre n always sit in the back seat
~ page 222, "C hild Safety" .
& WARNING
A child in a rearward-facing child safety seat installed on the front
passenger seat will be ser iously injured and can be killed if the
front airbag inflates - even with an Advanced Airbag System .
• The inflat ing airbag w ill hit the child safety seat or infant
carrier with great force and will smash the child safety seat and
child against the backrest, center armrest, door or roof .
• Always install rear-facing child safety seats on the rear seat .
• If you must install a rearward facing child safety seat on the
front passenger seat because of exceptional circumstances and
the PASSENGER AIR BAG OFF light does not come on and stay on,
immediately install the rear-facing child safety seat in a rear
seating position and have the airbag system inspected by your
authorized Audi dealer.
• Forward-facing child safety seats installed on the front
pa ssenger 's seat may interfere with the deployment of the airbag
and cause ser ious personal injury to the child.
& WARNING
If , in exceptional circumstances , you must install a forward-facing
c hild restraint on the front passenger's seat:
Controls and equip­ ment Safety first Vehicle operation
& WARNING
(co ntinued )
• 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 side airbag.
• Never put the forward-facing child restraint up against or very
near the instrument panel.
• Always move the passenger seat into its rearmost position in
the seat's fore and aft adjustment range, as far away from the
airbag as possible before installing the forward-facing child
restraint. The backrest must be ad justed to an upright position.
• Make sure that the PASSENGER AIR BAG OFF light comes on
and stays on all the time whenever the ignition is switched on.
& WARNING
To reduce the risk of serious injury, make sure that the
PASSENGER AIR BAG OFF light will 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 stay on, perform
the checks described~
page 211, "Monitoring the Advanced
Airbag System ".
• Take the child restra int off the front passenger seat and install
it properly at one of the rear seat positions if the PASSENGER AIR BAG OFF light does not stay on .
• Have the airbag system inspected by your authorized Audi
dealer immediately.
• Always carefully follow instructions from child restraint manu­
facturers when installing child restraints .

When a perso n is detected on the front passenger seat, weigh ing
more than the tota l weight of a child that is about 1 year old
restra ined in one of the rear-facing or forward-fac ing infant
restraints (listed in Federal Motor Vehicle Safety Standard
208 with
w hich the Advanced Ai rbag System in you r ve hicle was cert ified), the
front airbag on the passenger s ide may or may not dep loy .
T he
PA SSEN GER AIR BAG OFF light comes on when the elect ronic
control un it detects a total weight on the front passenger seat that
requires the front airbag to be turned off. If the
PAS SENGER AIR
BAG OFF
light does not come on, the front a irbag on the passenger
side has not been turned off by the control unit and can deploy if the
cont rol unit senses an impact that meets the conditions stored in its
memory .
If the total weight o n the fron t passenge r seat is more than that of a
typical
1 year-old, but less than the weight of a small adult, the fron t
airbag on the passenge r side may deploy (the
PASSENGER AIR BAG
OFF
light does not come on).
F o r example , the ai rbag may deploy if:
• a small chi ld tha t is heavie r th an a typ ica l 1 year-o ld child is on the
front passenger seat (regard less of whether the chi ld is in one of the
child safety seats listed ~
page 224),
• a child who has outgrown child restraints is on the front passenge r
seat.
If the front passenger a irbag is turned off, the
PASSENG ER AIR BAG
OFF
light in the center of the instrument panel wi ll come on and stay
on .
The front a irbag on the passenger side may
not deploy (the
PASSENGER AIR BAG OFF l ight does no t ill um inate and s tay lit) if:
• a small adu lt or teenager is on the front passenger seat •
a passenger who is not sitting upr ight w ith their back against a
non-recli ned backrest w ith their fee t on the vehi cle floor in front of
the seat is on the front passe nger seat.
If the front passenger airbag deploys, the Federal Standard requires
the airbag to meet the "low risk" deployment criter ia to help reduce
the risk of inj ury through interaction with the a irbag. "Low r isk"
dep loymen t oc cur s in those crashes t hat take pl ace at lower de celer­
ations as defined in the electronic contro l unit.~

• Never remove the front passenger or driver seat from the
vehicle.
• Never remove the uphol stery from the front passenger seat.
• Never disassemble or remove parts from the seat or disconnect
wires from it.
• Never carry sharp objects in your pockets or place them on the
seat. If the weight-sensing mat in the passenger seat is punctured
it cannot work properly.
• Never carry things on your lap or carry objects on the passenger
seat . Such items can increase the weight registered by the weight·
sensing mat and send the wrong information to the airbag control
unit.
& WARNING (c on tinued )
• Never store item s under the front passenger seat . Parts of the
Advanced Airbag System under the pa ssenger seat could be
damaged, p reventing them and the airbag system from working
properly.
• Never place seat covers or replacement upholstery that have
not been specifically approved by Audi on the front seats .
• Seat covers can prevent the Advanced Airbag System from
recognizing child restraints or occupants on the front passenger
se at and prevent the side airbag in the seat backre st from
deploying properly .
• Never use cushions , pillows, blankets or similar items on the
front passenger seat . The additional padding will prevent the
weight- sensing mat in the seat from accurately registering the
child restraint or person on the seat and prevent the Advanced
Airbag System from functioning properly.
• If you must use a child restraint on the front passenger seat
and the child restraint manufacturer's instructions require the use
of a towel, foam cu shion or something else to properly po sition
the child restraint , make certain that the PASSENGER AIR BAG
OFF light come s on and stays on whenever the child restraint is
installed on the front passenger seat.
• If the PASSENGER AIR BAG OFF light does not come on and
stay on , immediately install child restraint in a rear seating posi­
tion and have the airbag system inspected by your authorized Audi dealer .•

situations. Be sure to read the important information about safety
and heed the WARNINGS in this chapter.
Deployment of the Advanced A irbag System and the activation of the
safety belt pretensioners depend on the deceleration measured by
the crash sensors and registered by the electron ic control unit. T he
amount of inflation of the front airbags can a lso be adapted to the
front seat position, depending on the distance between the respec­
tive front seat and the steering wheel or instrument panel as regis­
tered by sensors in the seats. Crash severity depends on speed and
deceleration as well as the mass and stiffness of the vehicle or object
involved in the crash .
On the passenger side, regardless of safety belt use, the air bag w ill
be turned off if the weight on the passenger seat is less than the
amount programm ed in the electronic control unit . The front airbag
on the passenger side will also be turned off if one of the chi ld safety
seats that has been certified under Federal Motor Vehicle Safety
Standard 208 has been recognized on the seat. The
PASSENGER AIR
BAG OFF
light comes on and stays on to tell you when the front
Advanced Airbag on the passenger side has been turned off
=> page 202, "Child rest raints on the front seat -some important
things to know".
& WARNING
To reduce the risk of injury when an airbag inflates, always wear
safety belts properly.
• If you are unrestrained, leaning forward, sitting sideways or
out of position in any way, your risk of injury is much higher .
• You will also receive serious injuries and could even be killed if
you are up against the airbag or too close to it when it inflates •
even with an Advanced Airbag

More important things to know about front
airbags
Fig. 199 Inflated
front airbags
Safety belts are important to help keep front seat occupants in the
proper seated position so that airbags can unfold properly and
prov ide supplemental protection in a frontal collision.
Th e front airbags are designed to provide additiona l protection for
the chest and face of the driver and the front seat passenger when:
• safety belts are worn properly,
• the seats have been positioned so that the occupant is properly
seated as far as possible from the airbag ,
• and the head restraints have been properly adjusted .
Because airbags inflate in the blink of an eye with great force, things
you have on your lap o r have placed on the seat could become
dangerous projectiles, and be pushed into you if the airbag inflates.
When an airbag deploys, fine dust is released. This is normal and is
not caused by a fire in the vehicle. This dust is made up mostly of a
powder used to lubricate the airbags as they deploy .
It could irritate
skin.
It is important to remember that while the supplemental airbag
system is desig ned to reduce the likelihood of serious injur ies, other
injuries, for example swell ing, bruising and m inor abrasions, can also
happen when airbags inflate. Airbags do not protect the arms or the •
