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
instruct ions 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 .
Controls and equip­ ment Safety first
Vehicle operation
& 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.

Why safety belts?
Frontal co11isions and the law of physics
Front al crashes create very strong forces for pe ople rid ing
in vehicles.
Fi g. 185 U nbel ted

F ig . 18 6 The vehi cle
c ras hes in to the wa ll
The physical principles are simple. Both the vehicle and the passen­
gers possess energy which varies with vehicle speed and body
we ight. Engineers cal l this energy "kinetic energy ."
T he higher the speed of the vehicle and the greater the vehic le's
we ight, the more energy that has to be "absorbed" in the crash .
Vehicle speed is the most significan t factor. If the speed doubles
from 15 to 30 mph (25 to 50 km/h), the energy increases 4 times! .,

Aut om ati c sa fe ty belt re tra cto rs
Eve ry safety be lt is equipped with an automatic belt retractor on the
shoulder belt. This feature locks the belt when the belt is pulled out
fast, during hard braking and in an accident. The belt may a lso lock
when you drive up or down a steep hill or through a sharp curve .
During normal driving the belt lets you move free ly.
Safety belt prete nsi oners
The safety belts are equipped with a be lt pretensioner that he lps to
tighten the sa fety be lt and remove slack when the pretensioner is
activated. The function of the pretensioner is monitored by a
warning light=>
page 14 .
Swit chable locking fe ature
Every safety belt except the one on the driver sea t is equipped with
a switchab le locking feature that
must be used when the safety belt
is used to a ttach a chi ld safe ty sea t. Be sure to read the important
information about this feature=>

Child restraints on the front seat - some
important things to know
-Be sure to read the important information and head the
WARNINGS for important details about ch ildren and
Advanced Airbags~
page 213 .
Even though your vehic le is equipped with an Advanced Airbag
System, make certain that a ll children, especia lly those 12 years and
younger , always ride in the back seat proper ly restrained for their
age and size . The airbag on the passenger side makes the front seat
a potentia lly dangerous place for a child to ride. The front seat is not
the safest place for a chi ld 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 Ai rbag System in your vehicle has been certified to
comply with the Requirements of United States Federal Motor
Vehicle Safety Standard 208 as applicable at the time your vehicle
was manufactured.
The Standard requires the front airbag on the passenger side to be
turned off ("suppressed") if a chi ld up to about one year of age
restrained in one of the rear-facing or forward-facing infant res traints listed in Federa l Motor Vehicle Safety Standard 208 with
which the Advanced Airbag System in your vehicle was cert ified has
been insta lled on the front passenger seat. For a listing of the child
restraints that were used to certify compliance with the US Safety
Standard =>
page 215.
The PASS ENGER AIR B AG OFF light in the instrument panel tells you
when the front Advanced Airbag on the passenger side has been
t urned off by the electronic control unit.
Each time you turn on the ignition , the
PASSEN GER AIR BA G 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 occupied by an adult as
registered by the weight-sensing mat=>
page 199, "Monitoring the
Advanced Airbag System" .
The
P AS SENGER AIR BAG OFF light comes on when the control unit
detects a tota l weight on the front passenger seat that requires the
front airbag to be turned off.
If the total weight on the front passenger seat is more than that of
a typica l 1 year -old child but less than the weight of a small adult,
the front airbag on the passenger side can deploy (the
PA SSE NGER
A IR BA G OFF
light does not come on). If the P ASSE NGER AIR B AG
O FF
light does not come on, the front airbag on the passenger s ide
has not been turned off by the electronic control unit and can
deploy if the control unit senses an impact that meets the condi ­
tions stored in its memory.
F o r e xample , th e a ir b ag m ay dep loy if:
• a small ch ild 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 child safety seats listed
=> page 215), or
• a child who has outgrown chi ld restraints is on the front
passenger seat.
If the front passenger airbag is turned off, the
PASSEN GER AIR BA G
OFF
light comes on in the instrument cluster and stays on.
The fron t airbag on the passenger side may
not deploy (the
PA SS ENGER AIR BA G OFF light does not illuminate and stay lit) even
if a small adult or teenager, or a passenger who is no t sitting upright
with their back against a non -reclined backrest with their feet on the
vehic le floor in front of the seat is on the front passenger seat
=> page 170, "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 through interact ion with the airbag. "Low risk" d eploy­
ment occu rs in those crashes that take place at lower decelerations .,.

A lways remember, a chi ld safety seat or infant carrier insta lled on
the front seat may be struck and knocked out of position by the
rap id ly i nfla ting pass enger 's airbag in a frontal c olli sion . The airba g
co uld greatly reduce the effectiveness of the chi ld re straint and

& WARNING
A child in a rearward-facing child safety seat installed on the front
passenger seat will be seriously injured and can be killed if the
front airbag inflates - even with an Advanced Airbag System.
• The inflating airbag will hit the child safety seat o r 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 serious personal injury to the child .
& WARNING
If, in exceptional circumstances , you must install a forward-facing
child restraint on the front passenger's seat:
Controls and equip­ ment Safety first
Vehicle operation
& WARNING (continued)
• 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 adjusted 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 restraint 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 199 , "Monitoring the Advanced
Airbag System" .
• Take the child restraint 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 .
& WARNING
If, in exceptional circumstances, you must install a forward or
rearward-facing child restraint on the front passenger's seat :

a listing of the child restraints that were used to certify your
vehicle's compliance with the US Safety Standard=>
page 215,
• weight less than a threshold level stored in the control unit is
detected on the front passenger seat.
When a person is detected on the front passenger seat, weighing more than the total weight of a child that is about 1 year old
restrained in one of the rear-facing or forward-facing infant
restraints (listed in Federal Motor Vehicle Safety Standard
208 with
which the Advanced Airbag System in your vehicle was certified),
the front airbag on the passenger side may or may not deploy.
The
PASSENGER AIR BAG OFF light comes on when the electronic
control unit detects a total weight on the front passenger seat that
requires 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).
For example, the airbag may deploy if:
• a small child that is heavier than a typical 1 year-old child is on
the front passenger seat (regardless of whether the child is in one
of the child safety seats listed=>
page 215!,
• 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 in the center of the instrument panel will come on and stay
on.
The front airbag on the passenger side may
not deploy (the
PASSENGER AIR BAG OFF light does not illuminate and stay lit) if:
• a small adult or teenager is on the front passenger seat •
a passenger who is not sitting 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.
If the front passenger airbag deploys, the Federal Standard requires
the airbag to meet the "low risk" deployment criteria to help reduce
the risk of injury through interaction with the airbag . "Low risk"
deployment occurs in those crashes that take place at lower decel­
erations as defined in the electronic control unit.=>
page 199
Always remember:
Even though your vehicle is equipped with
Advanced Airbags, the safest place for children is properly
restrained on the back seat. Please be sure to read the important
information in the sections that follow and be sure to heed all of the
WARNINGS.
& 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=>
page 188.
& WARNING
A child in a rearward-facing child safety seat installed on the front
passenger seat will be seriously injured and can be killed if the
front airbag inflates -even with an Advanced Airbag System.
• Although the Advanced Airbag System in your vehicle is
designed to turn off the front airbag when a rearward -facing child
restraint has been installed on the front passenger seat, nobody
can absolutely guarantee that deployment is impossible in all
conceivable situations that may happen during the useful life of
your vehicle.

Advanced Airbag System components
The front passenger seat in your vehicle has a lot of very important
parts of the Advanced A irbag System in it. These parts inc lude the
weight -sensing mat, sensors, wiring, brackets, and more. The func -
Controls and equip­ ment Safety first Vehicle operation tion of the system in the front passenger seat is checked by
the elec­
tronic contro l unit when the ignition is on . The control unit monitors
the Advanced Airbag System and turns the a irbag indicator light on
when a malfunction in the system components is detected . The
function of the airbag indicator light is described in greater detail below. Because the front passenger seat conta ins important parts
of the Advanced Airbag System, you must take care to prevent 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.
T he front Ad van ced Airbag System consi sts of th e
following:
• Crash sensors in the front of the vehicle that measure vehicle
acce leration/deceleration to provide information to the Advanced
A irbag System about the sever ity of the crash .
• An electronic control unit, with integrated crash sensors for front
and side impac ts. The control unit "decides" whether to fire the
front airbags based on the information received from the crash sensors . The control unit also "decides" whether the safety belt
pretensioners should be activated.
• An Advanced Airbag w ith gas generator and contro l valve for the
driver inside the steering wheel hub.
• An Advanced Airbag with gas generator and contro l valve inside
the instrument panel 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 information registered is sent continuously to the e lectronic
control unit to regu late dep loyment of the front Advanced Airbag on
the passenger s ide.
• An airbag monito ring system and indicator light in the instru ­
ment cluster=> page
199.
• A sensor in each front sea t registers t he distance between the
respective seat and the steering wheel or instrument panel. The
information registered is sen t continuously to the electronic control
unit to regulate dep loyment of the front Advanced Airbags. ._

& WARNING
Damage to the front passenger seat can prevent the front airbag
from working properly .
• Improper repair or disassembly of the front passenger and
driver seat will prevent the Advanced Airbag Sy stem from func ­
tioning properly .
• Repairs to the front passenger seat must be performed by qual­
ified and properly tra ined workshop personnel .
• Never remove the front passenger or driver seat from the
vehi cle .
• 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 (continued )
• Never store items under the front passenger seat. Parts of the
Advanced Airbag System under the passenger seat could be damaged , preventing them and the airbag system from work ing
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 Sy stem from
recogn izing child restraints or occupants on the front passenger
s eat and prevent the side airbag in the seat backrest 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 cushion or something el se to properly position
the ch ild restraint , make certa in that the PASSENGER AIR BAG OFF
light comes 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 in stall child restraint in a rear seating position
and have the airbag system inspected by your authorized Audi
dealer .•
