using tire -rim combinations not approved by Audi, lowerin g the
ve hicle , ch ang ing the stiff ness of the suspe nsion, includ ing the
springs, suspension struts, shock absorbers etc. can chang e the
fo rces that a re measured by the airbag senso rs and se nt to the elec­

& WARNING
Changing the vehicle's suspension including use of unapproved
tire-rim combinations can change Advanced Airbag performance and increase the risk of serious personal injury in a crash.
• Never install suspension components that do not have the
same performance characteristics as the components originally
installed on your vehicle.
• Never use tire-rim combinations that have not been approved
by Audi.
& WARNING
Items stored between the safety belt buckle and the center
console can cause the sensors in the buckle to send the wrong
information to the electronic control module and prevent the
Advanced Airbag System from working properly .
• Always make sure that nothing can interfere with the safety
belt buckles and that they are not obstructed . •

Airbag system
Side airbags
Description of side airbags
The airbag system can provide supplemental protection
to properly restrained occupants.
Fig. 181 Side airbag
location in the driver's
seat
The side airbags are located in the sides of the front seat backrests
=> fig. 181 and the rear backrest* facing the doors. They are identi­
fied by the word "AIRBAG".
The side airbag system basically consists of: • the electronic control module and external side impact sensors
• the two side airbags located in the sides of the front backrests
• two rear side airbags (as an ordered
option)
• the airbag warning light in the instrument cluster .
Th e 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 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, front and rear*

passenger's upper torso on the side of the vehicle that is struck in a
side co llis ion. The airbag dep loys on ly in side impacts and only
when the vehic le acce leration registered by the control unit is high
enoug h. If this rate is below the reference va lue programmed into
the control unit, the side airbags will not be triggered, even though
the car may be badly damaged as a resu lt of the collision . It is not
possible to define an airbag trigger ing range that wi ll cover every
possible angle of impact, since the circumstances will vary consid ­
erab ly between one coll ision and another. I mportant factors
inc lude, for example, the nature (hard or soft) of the impacting
object, the angle o f impact, vehicle speed,
etc .=> page 205, "I m por ­
tant safety instructions on the side airbag system".
Aside from their normal safety funct ion, safety be lts work to help
keep the driver or front passenger in posit ion in the event of a side
collision so t hat the side airbags can provide protection.
The airbag system is
not a substitute for your safety belt. Rather, it
is part of the overa ll occupant restraint system in your vehicle .
A lways re m ember that t he side airbag system can on ly he lp to
protect you if you are wearing your safety be lt and wearing it prop ­
e rly. This is a nother reason why yo u should a lways wear you r safety
belts, not just because the law requires you to do
so=> page 176,
"General notes".
It is important to re m em ber that while the supp lemental side airbag
system is designed to reduce the like lihood of serious injuries, other
injuries, for example, swel ling, bru is ing, and minor abrasions can
a lso be associated with deployed side airbags. Remember too, side
a irbags wil l deploy o nly once and on ly in certain kinds of accidents
- your safety belts are a lways there to offer protection.
Vehicle damage, repair costs or even the lack of vehic le damage are
not necessari ly an indication of over-sensitive or failed airbag acti ­
vation. In some collisions, both front and side airbags may inflate.
Reme mber too, that a irbags w ill dep loy on ly once and on ly in
certain kinds of col lisions -your safety belts are always there to
offer pro tec tion in those acc ide nts in whic h airbags are not
supposed to deploy or when they have already deployed. T
he s ide a irbag sys te m will not d eplo y:
• whe n the ign ition is turned off
• in side collisions when the acce leration measured by the sensor
is t oo low
• in front-end co llisions
• in rear-end co llisions
• in ro llovers .
I n some types of accidents the front airbags, side curta in airbags
and side airbags may be triggered together.
& WARNING
• Safety belt s and the airbag sy stem will only prov ide protection
when occupant s are in the proper se ating posit ion
=> page 2 05 .
• If the airbag indic ator light come s on when the vehicle i s being
u sed , ha ve the sy stem inspe cted immed iat ely by y our authorized
Audi d ealer . The airbag may not work properly when the vehicle
a cc eler ation in a side colli sion is high enough to acti vate the
airba g.•

How supplemental side airbags work
Side airbags deploy instantly and can help reduce the risk
of upper torso injuries for occupants wh o are properly
restrained.

When the system is triggered, the airbag is fi lled with propel lant 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 o f a second a t very high
speed and with great force. The supplemental side airbag could
injure you if your seating pos it ion is not proper or upright or if items
are located in the area where the supplemental side airbag expands.
This app lies especially to
children => page 210, "Child Safety" .
Supplemental side airbags inflate between the occupant and the
door pane l on the side of the vehicle that is struck in certain side
coll ision
=> fi g. 182 .
A lthough 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 .

tion.
There is a lot that you and your passengers must know and act
accordingly to help the safety belts and ai rbags do their job to
provide supplementa l protection.
& WARNING
An inflating s ide airbag can cau se seriou s or f ata l injury . Imp rop ­
erly wear ing safety belts and improper seating pos ition s increase
the r isk of ser iou s per sonal injury and death whenever a vehicle i s
being used .
• In order to reduce the ri sk of injury when the suppleme nta l si de

&, WARNING (continued )
-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 in crease the risk of
injury in an accident by interfering with the way the airbag unfolds
or by being pu shed 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 .
• 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 per sonal injury in an accident.
• Alway s prevent the side airbags from being damaged by heavy
objects knocking against or hitting the sides of the seatba cks .
• 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 author ized Audi dealer.
• If children are seated improperly , their risk of injury increases
in the case of an
accident => page 210, "Child Safety".
&, WARNING (continued )
• 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
c losed.
- 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 .

& WARNING
• Safety belts and the airbag system will only provide protection
when occupants are
in the proper seating position ~ page 95,
"General recommendations".
• If the airbag indicator light comes on when the vehicle is being
used, have the system inspected immediately by your authorized
Audi dealer. The side curtain airbag may not work properly even
when the vehicle acceleration in a side collision is high enough to
activate the airbag.
•
How side curtain a irbags work
Side curtain airbags con work together with side airbags
to help reduce the risk of head and upper torso injuries for
occupants who ore properly restrained.
Fig . 184 Illustration of
principle: Inflated side
curtain airbags on the
left side
The side curtain airbags inflate between the occupant and the
windows on the side of the vehicle that is struck in a side collision
~ fig . 184. When the system is triggered, the side curtain airbag is filled with
propellant gas and breaks through a seam above the front and rear
side windows identified by the AIRBAG label. In order to help
provide this additional protection, the side curtain airbag must
inflate within the blink of an eye at very high speed and with great
force. The side curtain airbag could injure you if your seating posi ­
tion is not proper or upright or if items are located in the area where
the supplemental side curtain airbag inflates. This applies espe ­
cially to
children~ page 210.
Although they are not a soft pillow, side curtain airbags can
"cushion" the impact and in this way they can help to reduce the risk
of injury to the head and the upper part of the body .
A fine dust may develop when the airbag deploys. This is quite normal and does not mean there is a fire in the vehicle .•
Important safety instructions on the side
curtain airbag system
Airbags ore 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 do to
help the safety belts and airbags do their job to provide supple­
mental protection.
& WARNING
Improperly wearing safety belts and improper seating positions
increase the risk of serious personal injury and death whenever a
vehicle is being used .
• 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 SIDEGUARD head airbag can dangerously
interfere with its function. A deploying head airbag develops
enough force to catapult any piece of add-on component out of its
path of inflation and into the passenger compartment. An occu­
pant hit by such a projectile can suffer serious injury or death
=> page 349, "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 348, "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 protection .
• The airbag system can only be triggered once. If the airbag has
been triggered, the system must be replaced by an authorized
Audi dealer or qualified workshop.
• Always have work involving the side curtain airbag system,
removal and installation of the airbag components, or other
repairs performed by a qualified dealership. Otherwise the airbag
system may not work correctly.
• Never attempt to modify any components of the airbag system
in any way. •

Child Safety
Important things to know
Introduction
The rear sea t is generally the safest place in a collision.
The physica l princ iples of what happe ns w hen your ve hicle is in a
crash app ly also to children
=> page 178, "What happens to occu ­
p a nts no t wearing safe ty belts?" . But un lik e adu lts and teenagers,
their musc les and bones are not fu lly developed. In many respects
children are at greate r risk of ser ious injury in cras hes than adul ts .
Because c hildren 's bodies are not ful ly deve loped, they require
restraint systems esp ecially designed for their size, weight, and
body st ructure. Many countr ies a nd al l states of the U nited States
and provinces of Canada have laws requiring the use of approved
ch ild restrai nt sys te m s for infant s and smal l chil dren.
I n a fronta l crash at a speed of 20 -35 mph (30 -56 km/h) the forces
ac tin g on a 13 -p o un d (6 kg) infant wil l be m ore tha n 20 times the
weight of t he child . T his means the weight of the c hild would
suddenly be more than 260 pounds (120 kg). Under these condi ­
tions, on ly an appropriate child restraint properly used can reduce
the risk of serious injury. Child restraints, like adult safety belts,
m ust be use d properly t o be eff ec tive. Use d imp ro perly, they ca n
increase the risk of serious injury in an accident .
Co nsu lt t he c hild sa fe ty seat manu fac ture r's ins truc tions to be su re
the seat is r ight for your child's
size=> page 213, "Important safety
instructions for using child safety seats" . Please be sure to read and
heed a ll of the important information and WARN INGS about child
safety , Advanced Airbags, and the installation of child restraints in
th is chapter.
T here is a lot you need to know about the Advanced Airbags in your
ve hicle and how they work whe n infan ts and c hildr en in child
restra ints are on the front passenger seat . Because of the large a
m ount of i mportant in formation, we cannot repeat it a ll here. We
urge you to read the detai led information in this owner's manua l
about a irbags and the Advanced Airba g Sys te m in your ve hicle an d
the very i mportant information about transporting chi ldren on the
fr on t passe nger seat . P lease be su re to hee d t he WAR NINGS
-they
are extreme ly important for your safety and the safety of your
p assengers, es pec ial ly in fa nt s and s mall chil dren .
& WARNING
• Accident statistics have shown that children are generally safer
in the rear seat area than in the front seat ing 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 or impa ct. An unrestrained or improperly restrained
child is also at greater risk of injury or death through contact with
an inflating airbag .
• A suitable child restraint properly installed and used at one of
the rear seating positions prov ides the highest degree of protec­
tion for infants and small children in most accident situations.
& WARNING
Children on the front se at of any car even with Advanced Airbags
can be seriously injured or even killed when an airbag inflates . A
child in a rearward -fa cing child safety seat in stalled on the front
passenger seat will be seriously injured and can be killed if the
front airbag inflates .
• The inflating airbag will hit the child safety seat or infant
carrier with great force and will smash the child safety seat and
c hild against the backrest , center arm rest , or door . ..,_
