is why you should always wear your safety belt, not just because the
l a w requ ire s you to do so =>
page 211, "Genera l 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 s lightly higher rate of deceleration than if the belt is
not be ing used . Therefore, in a par ticular collision, it is possib le that
an airbag will not deploy a t a seating position where the safety belt
is be ing used but will inflate at the position where the safety belt is
not being used .
Remember too, airbags will deploy only once and only in ce rtain
kinds o f accidents - your safety be lts are always there to offer
protection in those accidents in wh ich airbags are not supposed to
deploy or when they have already deployed, for examp le when you r
vehicle strikes or is struck by another after the first collision.
T his is just one of the reasons why an ai rbag is not a substitute for
the safety be lt. The airbag system works most effectively when used
with the safety belts . Therefore, a lways wear your safety belts
correctly.
I t is important to remember that while the supplemental airbag
system is designed to reduce the like lihood of ser ious injuries, o ther
injuries, for example, swelling, bruising, and minor abrasions can
a lso be associated with airbags.

& WARNING
An inflating knee airbag can cause serious injury. Wearing safety
belts incorrectly and improper seating positions increase the risk
of serious personal injury and death whenever a vehicle is being
used .
• The airbag system cannot protect you properly if you are
seated too clo se to any of the airbag locations. When adjusting
& WARNING (continued)
their seat positions , it is important that both the driver and the
front passenger keep their upper bodies and knees at the
follow ing min imum 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 r isk 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 w ith the
way the airbag deploys or by being pushed into you as the a irbag
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 airb ag. Sm all 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 protecti on
to properly rest rained occupants.
Fi g. 238 Si de a ir b ag
lo ca tio n in th e driv er's
seat
The side airbags are located in the sides of the front seat backrests
=> fig. 238 and the rear backrest facing the doors . They are identified
by the word "AIRBAG" .
The sid e ai rbag sy stem b asica lly consis ts of :
• t he electronic control module and external side impact sen sors
• the two side airbags located in the sides of the front backrests
• two rear side airbags
• the a irbag warning light in the instrument cluster.
The airbag system is monitored electronically to make certain that it is functioning properly at all times. Each time you turn on the igni ­
tion, the airbag system indicator light wi ll 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, front and rear 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 on ly when the
vehicle acceleration registered by the control unit is high enough . If
Safety first
Airb ag sy ste m
this rate is below the reference value programmed into the control
unit, the side airbags w ill not be triggered, even though the car may
be badly damaged as a result of the col lision. It is not possible to
define an airbag triggering range that wi ll cover every possible
ang le of impact, since the circumstances will vary considerably
between one collision and another. Important factors include, for
examp le, the nature (hard or soft) of the impacting object, the angle
of impact, vehicle speed, etc.=>
page 240, "Important safety instruc ­
tions on the side airbag system".
Aside from their norma l safety function, safety belts work to he lp
keep the driver or front passenger in position in the even t of a side
collision so that the side airbags can provide protection .
The airbag system is
not a substitute for your safety belt. Rathe r, it
is part of the overall occupant restraint system in your vehicle.
Always remember that the side airbag system can only he lp to
pro tect you if you are wearing your safety belt and wear ing 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 211,
"General notes" .
I t is important to remember that while the supplementa l side airbag
system is designed to reduce the likelihood of serious injuries, other
injuries, for example, swelling, bruising, and minor abrasions can
a lso be associated with deployed s ide airbags . Remember too, side
airbags will deploy only once and only in certain kinds of accidents
- your safety belts are always there to offer pro tec tion .
Vehicle damage, repair costs or even the lack of vehicle damage are not necessarily an indication of over -sensitive or failed airbag acti ­
vation . In some collisions, both front and side airbags may inflate.
Remember too, that airbags will deploy on ly once and only in
certain kinds of collisions -your safety belts are always there to
offer protection in those acc idents in which airbags are not
supposed to deploy or when they have already dep loyed.
The sid e airbag system w ill not deploy :
• when the igni tion is turned of f

• in side collisions when the acceleration measured by the sensor
is too low
• in front -end collisions
• in rear -end collisions
• in rollovers.
In some types of accidents the front airbags, side curtain airbags
and side airbags may be triggered together.
& WARNING
• Safety belts and the airbag system will only provide protection
when occupants are in the proper seating position
~ page 240.
• If the airbag indicator light comes on when the vehicle is being
used , have the system inspected immediately by your authorized
Audi dealer . The airbag may not work properly when the vehicle
acceleration in a side collision is high enough to activate the
airbag .•
How supplemental side airbags work
Side airbags deploy instantly and can help reduce the risk
of upper torso injuries for occupants who are properly
restrained.
Fig. 239 Inflated side
airbags on left side of
vehicle, rear s ide
airbag
When the system is triggered, the airbag is filled with propellant gas
and breaks through a seam in the seat surface area marked
"AIRBAG" . It expands between the side trim panel and the
passenger. In order to he lp provide this additional protection, the
side airbag must inflate within a fraction of a second at very high
speed and with great force . The supplemental side airbag could
injure you if your seating position is not proper or upright or if items
are located in the area where the supplemental side airbag expands.
This applies especially to children~
page 245, "Child Safety".
Supplem ental side airbags inflate between the occupant and the
door panel on the side of the vehic le that is struck in certain side
collision~ fig. 239.
Although they are not a soft pillow, they can "cushion" the impact and in this way they can he lp to reduce the risk of injury to the upper
part of the body.
A fine dust may develop when the airbag deploys. This is normal
and does not mean there is a fire in the vehicle. •
Important safety instructions on the side
airbag system
Airbags are only supplemental restraints. Always prop­
erly wear safety belts and ride in a proper seating posi­
tion .
There is a lot that you and your passengers must know and act
accordingly to help the safety belts and airbags do their job to
provide supplementa l protection.
& WARNING
An inflating side airbag can cause serious or fatal injury. Improp ­
erly wearing safety belts and improper seating positions increase
the risk of serious personal injury and death whenever a vehicle is
being used . _.,

& WARNING (continued)
• In order to reduce the risk of injury when the supplemental side
airbag inflates:
-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.

& WARNING (continued)
-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 .
• 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 245, "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

The side curtain airbags are located on both sides of the interior
above the front and rear side windows~ fig. 240. They are identi ­
fied by the word "AIRBAG" on the windshield frame and the center
roof pillar.
The side curtain airbag system supplements the safety belts and can help to reduce the risk of injury for occupants' heads and upper
torso on the side of the vehicle that is struck in a side collision. The
side curtain airbag inflates only in side impacts and on ly when the
vehic le acceleration registered by the control unit is high enough . If
t his rate is below the re ference value programmed into the control
unit, the side airbags will not be triggered, even though the car may

& WARNING (continued)
• Never let occupants place any parts of their bodies in the area
from which the side curtain airbags inflate .
• Always make sure that the side curtain airbags can inflate
without interference . Unsuitable accessories fitted inside the
expansion range of a side curtain airbag can dangerously interfere
with its function. A deploying head airbag develops enough force
to catapult any p iece of add-on component out of its path of infla­
tion and into the passenger compartment. An occupant hit by such a projectile can suffer serious injury or death

"Technical Modifications" .
• Do not swivel the sun visors to the side if you have any objects
clipped onto them (for example pens). If the airbag should deploy ,
you could be injured by these objects .
• 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 airbag deployment and can cause personal injury in
an accident .
• Never use hangers to hang clothing from the hooks .
• Only use factory -installed sun shades or, in the case of shades
installed after the vehicle leaves the factory , only Audi roll -up
sunscreens may be used
=> page 384, "Additional accessories and
parts replacement" .
• Always sit in proper seating position and wear safety belts
while traveling so that the side curtain airbags can help provide

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 213, "What happens to occu ­
pa nts not wearing safety bel ts?" . But 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 injury in cras hes than a dults .
B ecause chi ldren's bodies are 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
acting 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 used properly t o be effective. Used 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 248, "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 ac cident situations .
& WARNING
Children on the front seat of any car even with Advanced Airb ag s
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 sma sh the child safety seat and
child against the backrest , center arm rest , 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 ..,.
