is why you should always wear your safety belt, not just because the
law requires you to do so~
page 125, "General notes".
The safety belt buckle for the driver and front seat passenger have switches that tell the airbag control module if the safety belt is
being used or not . If the safety belt is being used, the knee airbag
will deploy at a slightly higher rate of deceleration than if the belt is
not be ing used. Therefore, in a part icular collision, it is possible that
an airbag will not deploy at a seating position where the safety belt
is being used but will inflate a t the position where the safety belt is
not being used .
Remember too, airbags wi ll deploy only once and only in certain
kinds o f accidents -your safety belts are a lways there to offer
protection in those accidents in which airbags are not supposed to
deploy or when they have already deployed, for example when your
vehic le strikes or is struck by another after the first collision .
This is just one of the reasons why an airbag is not a substitute for
the safety be lt . The airbag system works most effectively when used
with the safety bel ts. Therefore, always wear your safety belts
correctly .
It is important to remember that while the supplemental airbag
system is des igned to reduce the likelihood of serious injuries, other
injuries, for example, swelling, bruising, and minor abrasions can
a lso be associated with airbags.

their seat positions, it is important that both the driver and the
front passenger keep their upper bodies and knees at the
following minimum safe distances:
- 1
O inches (25 cm) between the chest and the steering
wheel /instrument panel .
- 4 inches (10 cm) between the knees and the lower part of the instrument panel .
• The risk of personal injury increases if you lean forward or to
the side, or if the seat is improperly positioned and you are not
wearing your safety belt . The risk increases even more should the
airbag deploy .
• Always make sure that the knee airbag can inflate without
interference . Objects between yourself and the airbag can
increase the risk of injury in an accident by interfering with the
way the airbag deploys or by being pushed into you as the airbag
deploys .
- No persons (children) or animals should ride in the footwell
in front of the passenger seat . If the airbag deploys , this can
result in serious or fatal injuries .
- No objects of any kind should be carried in the footwell area
in front of the driver's or passenger's seat . Bulky objects (shop­
ping bags , for example) can hamper or prevent proper deploy­
ment of the airbag . Small objects can be thrown through the
vehicle if the airbag deploys and injure you or your passengers .
• Make sure there are no cracks, deep scratches or other damage
in the area of the instrument panel where the knee airbags are
located .
• If children are incorrectly seated, their risk of injury increases in
the case of an accident=>

Side airbags
Description of side airbags
The airbag system can provide supplemental protection
to properly restrained front seat occupants.
Fig. 1 16 S ide a irbag
l oca tion i n the drive r's
seat
The side airbags are located in the sides of the front seat backrests
~ fig. 116 facing the doors. They are identified by the word
"AIRBAG".
Th e s ide a irba g sys te m bas ica lly consis ts o f:
• the e lectronic control module and external side impact sensors
• the two side airbags located in the sides of the front backrests
• the airbag warning light in the instrument cluster .
The airbag system is monitored electronica lly to make certain that
it is functioning properly at all times . Each time you turn on the igni ­
tion, the airbag system indicator light will come on for a few
seconds (self diagnostics).
The side airbag system supplements the safety belts and can help
to reduce the risk of injury to the driver's and front passenger's
upper torso on the side of the vehicle that is struck in a side colli­
sion . The airbag deploys only in side impacts and only when the
vehic le acceleration registered by the control unit is high enough. If
this rate is below the reference value programmed into the control unit, the side airbags will not be
triggered, even though the car may
be badly damaged as a result of the collision. It is not possible to
define an airbag triggering range that wi ll cover every possible
angle of impact, since the circumstances will vary considerab ly
between one collision and another . Important factors include, for
example, the nature (hard or soft) of the impacting object, the angle
of impact, vehicle speed, etc.~
page 155, "Important safety
instructions on the side airbag system" .
Aside from their normal safety function, safety belts work to he lp
keep the driver or front passenger in position in the event of a side
collision so that the side airbags can provide protection.
The airbag system is
not a subs titute for your safety belt. Rather, it
is part of the overall occupant restraint system in your vehicle .
Always remember that the side airbag system can only help to protect you if you are wearing your safety belt and wearing it prop ­
erly. This is another reason why you should always wear your safety
belts, not just because the law requires you to do so~
page 125,
"General notes" .
It is important to remember that while the supplemental side airbag
system is designed to reduce the likelihood of serious injuries, other
injuries, for example, swel ling, bruis ing , and minor abrasions can
also be associated with deployed side airbags . Remember too, side
airbags will deploy only once and only in certain kinds of accidents
- your safety belts are a lways there to offer protection.
Vehicle damage, repair costs or even the lack of vehicle damage are not necessarily an indication of over-sensitive or failed airbag acti­
va tion . In some collisions, both front and side airbags may inflate .
Remember too, that airbags will deploy only once and only in
certain kinds of col lisions -your safety belts are a lways there to
offer protection in those accidents in which airbags are not
supposed to deploy or when they have already deployed .
The s ide a irba g sy stem wi ll not deploy :
• whe n the ignition is turned off
• in side collisions when the acceleration measured by the sensor
is too low
~

• in front -end collisions
• i n rea r-en d col lis ions
• in ro llovers.
In som e types o f acci dents th e fron t air bags a nd s ide airbags m ay
be trigge red together.
& WARNING
• Safety belts and the airbag system will only provide protect ion
when occupants are in the proper seating position
=> page 155 .
• If the a irbag indicator light comes on when the vehicle is being
used, have the system inspected immediately by your authorized
Audi dealer . The a irbag may not work properly when the vehicle
acceleration in a side collision is high enough to a ctivate the
airbag .•
How supplemental side airbags work

s ide a irbag must inflate w ithin a fraction of a second at very high
speed a nd w ith grea t force. T he suppleme ntal side ai rbag could
injure you if your seating position is not proper or upright or if items
are located in the a rea where the s upp lemental si de air bag expands .
This applies especial ly to child ren=>

& WARNING (continued)
- Always sit in an upright position and never lean against the
area where the supplemental side airbag is located.
- Never let a child or anyone else rest their head against the
side trim panel in the area where the supplemental side airbag
inflates .
- Always make sure that safety belts are worn correctly,
- Do not let anyone sitting in the front seat put their hand or any other parts of their body out of the window.
• Always make sure that the side airbag can inflate without inter ­
ference.
- Never install seat covers or replacement upholstery over the front seat backs that have not been specifically approved by
Audi.
- Never use additional seat cushions that cover the areas
where the side airbags deploy .
- Damage to the original seat covers or to the seam in the area
of the side airbag module must always be repaired immedi­
ately by an authorized Audi dealer.
• Objects between you and the airbag can increase the risk of
injury in an accident by interfering with the way the airbag unfolds
or by being pushed into you as the airbag inflates .
- Never place or attach accessories or other objects (such as
cup holders , telephone brackets, or even large, bulky objects)
on the doors , over or near the area marked "AIRBAG" on the
seat backrests .
- Such objects and accessories can become dangerous projec ­
tiles and cause injury when the supplemental side airbag
deploys.
- Never carry any objects or pets in the deployment space
between them and the airbags or allow children or other
passengers to travel in this position.
& WARNING (continued)
• Always use the built-in coat hooks only for lightweight
clothing. Never leave any heavy or sharp -edged objects in the
pockets that may interfere with side airbag deployment and can
cause personal injury in an accident .
• Always prevent the side airbags from being damaged by heavy
objects knocking against or hitting the sides of the seatbacks.
• The airbag system can only be triggered once.
If the airbag has
been triggered, the system must be replaced by an authorized
Audi dealership .
• Damage (cracks , deep scratches etc.I to the original seat covers
or to the seam in the area of the side airbag module must always
be repaired immediately by an authorized Audi dealer .
• If children are seated improperly, their risk of injury increases
in the case of an accident~
page 157, "Child Safety ".
• Never attempt to modify any components of the airbag system
in any way .
• In a side collision , side airbags will not function properly if
sensors cannot correctly measure increasing air pressure inside
the doors when air escapes through larger , unclosed openings in
the door panel.
- Never drive with interior door trim panels removed.
-Never drive when parts have been removed from the inside
door panel and the openings they leave have not been properly
closed .
- Never drive when loudspeakers in the doors have been
removed unless the speaker holes have been properly closed.
- Always make certain that openings are covered or filled if
additional speakers or other equipment is installed in the
inside door panels .
- Always have work on the doors done by an authorized Audi
dealer or qualified workshop . •

Child Safety
Important things to know
Introduction
The rear seat is generally the safes t place in a collision.
The p hysica l pr inciples of what happens when you r veh ic le is in a
crash apply also to children=>
page 127, "What happens to occu ­
p a nts not wearing safety bel ts?" . Bu t un like adults and teenagers,
their musc les and bones are not fully developed. In many respects
children a re a t greater ris k of serious inj ury in cras hes than a dults .
B ecause chi ldren's bodies a re no t fully deve loped, they require
restraint systems especial ly designed for their size, weight, and
body structu re. Ma ny countries and al l sta tes of the U nited States
and provinces of Canada have laws requiring the use of approved
chil d restraint sys te m s for infa nts and smal l children .
I n a frontal crash at a speed of 20 -35 mph (30 -56 km/h) the forces
ac ting on a 13-pou nd (6 kg) infant wi ll be mo re than 20 times the
weight of the child. This means the weight of the child would
suddenly be more than 260 pounds ( 120 kg). Under these condi ­
t ions, only an appropriate child restraint proper ly used can reduce
the risk of serious injury. Child restraints, like adult safety belts,
must be use d properly t o be eff ective. Use d impro perly, they can
increase the risk of serious injury in an accident.
Co nsul t the c hild safety seat man ufacture r's ins truc tions to be su re
the seat is right for your child's size=>
page 160, "Important safety
instructions for using child safety seats" . Please be sure to read and
heed a ll of the important information and WARNI NGS about child
safety, Advanced Airbags, and the insta llation of child restraints in
this chapter.
T here is a lot you need to know about the Advanced Airbags in your
veh ic le and how they work whe n inf an ts and ch ild ren in c hild
restraints are on the front passenger seat. Because of the large
Controls and equip­ ment Safety first Vehicle operation
amoun
t of important informat ion, we cannot repeat it all here. We
urge you to read the detai led information in this owner's manua l
about a irbags and the Advanced Airbag Sys tem in your ve hic le and
the very important information about transporting children on the
fr ont passenger sea t. Please b e sure to hee d th e WAR NINGS -th ey
are extreme ly important for your safety and the safety of your
p asse ngers, es pecia lly inf ant s and s mall ch ildren .
& WARNING
• Accident statistics have shown that children are generally safer
in the rear seat area than in the front seating position . Always
restrain any child age 12 and under in the rear.
• All vehicle o ccupants and especially children must be
restrained properly whenever riding in a vehicle . An unrestrained
or improperly restrained child could be injured by striking the inte­
rior or by being ejected from the vehicle during a sudden
maneuver o r impact . An unrestrained or improperly restrained
c hild is also at greater risk of injury or death through conta ct with
an inflating a irbag .
• A suitable child restraint properly installed and used at one of
the rear seating positions provides the highest degree of protec­
tion for infants and small children in most accident situations .
& WARNING
Children on the front seat of any car even with Advanced Airb ags
c an be seriously injured or even killed when an airbag inflates . A
child in a rearward -fa cing child safety seat installed on the front
pas senger seat will be seriously injured and can be killed if the
front airbag inflates.
• The inflating airbag will hit the ch ild safety seat or infant
carrier with great force and will smash the child safety seat and
child against the backrest or door. •

Advanced front airbag system and children
Your vehicle is equipped with an "Advanced Airbag System" in
complia nce with United States Federa l Motor Vehicle Safety Stan ­
dard (FMVSS) 208 as applicable at the time your vehicle was manu ­
factu red. T
he Advanced Airbag system in your vehicle has been certified to
meet the " low -risk" requirements for 3 and 6 year -old chi ldren on
the passenger side and smal l adults on the driver side . The low risk
deployment criteria are intended to reduce the risk of injury through
interaction with the 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 up to 12 months who are restrained on
the front passenger seat in child restraints that are listed in the
S tandard.
Even though your vehicle is equipped with an Advanced Airbag
system, all ch ildren, especially those 12 years and younger, should
always ride in the back seat properly restrained for their age and
size . The airbag on the passenger side makes the front seat a poten­
tially dangerous p lace for a child to ride. The front seat is not the
safest p lace for a child in a forward -facing child safety seat. It can be
a very dangerous p lace for an infant or a larger ch ild in a rearward­
facing seat. •
Advanced Airbags and the weight-sensing
mat in the front seat
The Advanced Airbag System in your vehicle detects the presence
of an infant or child in a chi ld restraint on the front passenger seat
using the weight -sensing mat in the seat cushion and the sensor
below the safety belt latch on the front passenger seat that
measures the tension on the safety belt.
The weight -sensing mat measures total weight of the chi ld and the
child safety seat and a child blanket on the front passenger seat . The
weight on the front passenger seat is related to the design of the
child restraint and its "footprint", the size and shape of the bottom
of the child restraint as it sits on the seat . The weight of a child
restraint and its "footprint" vary for different kinds of child ..,.

-----------------------------------------~C::_! h~ i~ ld ~ S~a !_!f ~e _!;tY L _lffl!III
restraints and for the different models of the same kind of child
restraint offered by child restraint manufacturers.
The weight ranges for the individual types, makes and models of
child restraints that the NHTSA has specified in the Safety Standard
together with the weight ranges of typ ical infants and typical 1 year­
old child have been stored in the control unit of the Advanced
Airbag System. When a child restraint is being used on the front
passenger seat with a typical 1 year -old child, the Advanced Airbag
System compares the weight measured by the weight sensing mat
with the information stored in the electronic control unit.
The electronic control unit also registers the tension on the front
passenger safety belt. The tension on the safety belt for the front
passenger seat will be different for an adult who is properly using
the safety belt as compared to the tension on the belt when it is
used to attach a child restraint to the seat. The sensor below the
latch for the safety belt for the front seat passenger measures the
tension on the belt . The input from this sensor is then used with the
weight to "decide" , whether there is a child restraint with a typical 1
year-old child on the front passenger seat and whether or not the airbag must be turned off.•
Child restraints and Advanced Airbags
Regardless of the child restraint that you use, make sure that it has
been certified to meet United States Federal Motor Vehicle Safety
Standards and has been certified by its manufacturer for use with
an airbag. Always be sure that the chi ld restraint is properly
installed at one of the rear seating positions. If in exceptiona l
circumstances you must use it on the front passenger seat, carefully
read all of the information on child safety and Advanced Airbags
and heed a ll of the applicable WARNINGS. Make certain that the
child restraint is correctly recognized by the weight -sensing mat
inside the front passenger seat, that the front passenger airbag is
turned off and that the airbag status is always correctly signaled by
th e
PASSENGER AIR BAG OFF light .
Controls and equip­
ment Safety first Vehicle operation
Many
types and models of child restraints have been available over
the years, new mode ls are introduced regularly incorporating new
and improved designs and older mode ls are taken out of produc­
tion. Child restraints are not standardized . Child restraints of the
same type typically have different weights and sizes and different
'footprints,' the size and shape of the bottom of the chi ld restraint
that sits on the seat, when they are installed on a vehicle sea t. These
differences make it virtual ly impossible to certify comp liance with
the requirements for advanced airbags with each and every child
restraint that has ever been sold in the past or will be sold over the
course of the usefu l life of your vehic le.
For this reason, the United States National Highway Traffic Safety
Administration has pub lished a list of specific type, makes and
models of child restraints that must be used to certify compliance
of the Advanced Airbag System in your vehicle with the suppression
requirements of Federal Motor Vehicle Safety Standard 208. These
child restraints are:
A. Car beds, manufactured on or after September 1,
2004:
• Cosco Dream Ride 02-719
B. Rear facing child restraint systems, manufactured
