Airbag system

— the electronic control module and external side
impact sensors
— the two airbags located in the sides of the front
backrests and the two airbags* located in the
rear backrest
— the airbag warning light in the instrument clus-
ter.
The airbag system is monitored electronically to
make certain that it is functioning properly at all
times. Each time you switch on the ignition, 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 ina
side collision. The airbag deploys only in side im-
pacts and only when the vehicle acceleration reg-
istered by the control unit is high enough. If this
rate is below the reference value programmed in-
to 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 pos-
sible to define an airbag triggering range that
will cover every possible angle of impact, since
the circumstances will vary considerably between
one collision and another. Important factors in-
clude, for example, the nature (hard or soft) of
the impacting object, the angle of impact, vehicle
speed, etc. > page 273, Important safety in-
structions on the side airbag system.
Aside from their normal safety function, safety
belts work to help keep the driver or front pas-
senger in position in the event of a side collision
so that the side airbags can provide protection.
The airbag system is not a substitute for your
safety belt. Rather, it is part of the overall occu-
pant restraint system in your vehicle. Always re-
member that the side airbag system can only
help to protect you if you are wearing your safety
belt and wearing it properly. This is another rea-
son why you should always wear your safety
belts, not just because the law requires you to do
so > page 245, General notes.
It is important to remember that while the sup-
plemental side airbag system is designed to re-
272
duce the likelihood of serious injuries, other inju-
ries, for example, swelling, bruising, friction
burns 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 always
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 activation. In
some collisions, both front and side airbags may
inflate. Remember too, that airbags will deploy
only once and only in certain kinds of collisions -
your safety belts are always there to offer protec-
tion in those accidents in which airbags are not
supposed to deploy or when they have already
deployed.
The side airbag system will not deploy:
— when the ignition is switched off
— in side collisions when the acceleration meas-
ured 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.

ZA WARNING
— Safety belts and the airbag system will only
provide protection when occupants are in
the proper seating position > page 273.
- If the airbag indicator light > page 238
comes when the vehicle is being used, have
the system inspected immediately by your
authorized Audi dealer. It is possible that
the airbag will inflate when it is not sup-
posed to, or will not inflate when it should.

How supplemental side airbags work
Side airbags deploy instantly and can help re-
duce the risk of upper torso injuries for occu-
pants who are properly restrained.

Fig. 223 Side impact protection: inflated side airbags
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 ex-
pands between the side trim panel and the pas-
senger. In order to help 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 ap-
plies especially to children > page 278, Child
safety. Supplemental side airbags inflate be-
tween the occupant and the door panel on the
side of the vehicle that is struck in certain side
collision > fig. 222, > fig. 223.
Although they are not a soft pillow, they can
“cushion” the impact and in this way they can
help 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
properly wear safety belts and ride in a proper
seating position.
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 supplemental
protection.

ZA WARNING
An inflating side airbag can cause serious or
fatal injury. Improperly wearing safety belts
and improper seating positions increase the
risk of serious personal injury and death
whenever a vehicle is being used.
— 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 supple-
mental 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 interference.
— Never install seat covers or replacement
upholstery over the front seatbacks that
have not been specifically approved by
Audi.
— Never use additional seat cushions that
cover the areas where the side airbags de-
ploy.


273

Airbag system


— 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 in-
terfering with the way the airbag unfolds or
by being pushed into you as the airbag in-
flates.
— 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 projectiles and cause injury
when the supplemental side airbag de-
ploys.
— Never carry any objects or pets in the de-
ployment space between them and the air-
bags 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.) 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 278, Child safety.
— Never attempt to modify any components of
the airbag system in any way.
— Ina side collision, side airbags will not func-
tion properly if sensors cannot correctly
measure increasing air pressure inside the

274
doors when air escapes through larger, un-
closed 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 open-
ings 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 work-
shop.

The side curtain airbag system supplements the
safety belts and can help to reduce the risk of in-
jury for occupants’ heads and upper torso on the
side of the vehicle that is struck in a side colli-
sion. The side curtain airbag inflates in side im-
pacts and only when the vehicle acceleration reg-
istered by the control unit is high enough. If this
rate is below the reference value programmed in-
to the control unit, the side curtain airbag 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 will cover every possible angle of impact,

tween one collision and another. Important fac-
tors include, for example, the nature (hard or
soft) of the impacting object, the angle of im-
pact, vehicle speed, etc. > page 276, How side
curtain airbags work.
Aside
from their normal safety function, safety
belts work to help keep the driver or front pas-
senger in position in the event of a collision so
that the side curtain airbags can provide protec-
tion.

for example, swelling, bruising, friction burns
and minor abrasions can also be associated with
these airbags upon deployment. Remember too,
these airbags will deploy only once and only in
certain kinds of accidents - your safety belts are
always there to offer protection.
The side curtain airbag system basically
consists of:
— The electronic control module and external side
impact sensors
— The side curtain airbags above the front and
rear side windows with ejection mitigation fea-
tures
— The airbag indicator light in the instrument
panel
The airbag system is monitored electronically to
make certain it is functioning properly at all

Fig. 225 Illustration of principle: Inflated side curtain air-
bags on the left side (example)
The side curtain airbags inflate between the oc-
cupant and the windows on the side of the vehi-
cle that is struck in a side collision > fig. 225.
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 position is not proper or upright or if
items are located in the area where the supple-
mental side curtain airbag inflates. This applies
especially to children > page 278.
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

Important safety instructions on the side
curtain airbag system
Applies to: vehicles with side curtain airbags
Airbags are only supplemental restraints. Always
properly wear safety belts and ride in a proper
seating position.
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 supplemental protection.

ZA 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 cur-
tain airbag inflate.
— Always make sure that the side curtain air-
bags can inflate without interference.
— Use the built-in coat hooks only for light-
weight clothing. Never leave any heavy or
sharp-edged objects in the pockets that may
interfere with airbag deployment and can
cause personal injury in a collision.
— Never use hangers to hang clothes on the
hooks.
— Only use factory-installed sun shades or, if
shades installed after the vehicle leaves the
factory, use only genuine Audi sun shades.
— Never swing the sun visors over to the side
windows if things such as pens, garage door
openers, hands-free speakers, etc. are at-
tached to the sun visors. They could come
loose and cause serious injury if the side cur-
tain airbag inflates.
— A deploying airbag inflates in a fraction of a
second and with great force.
— Never attach objects to the cover or in the
deployment zone of a side curtain airbag.
— The airbag deployment zones must be kept
clear at all times. Make sure there are no ob-
jects, pets, or other persons in the space be-
tween any vehicle occupant and any airbag
at any time.
— Do not attach any accessories to the doors.

— The airbag system can deploy only 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 per-
formed 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

Child safety
Important information
Introduction
The rear seat is generally the safest place ina
collision.
The physical principles of what happens when
your vehicle is in a crash apply also to children
= page 246, What happens to occupants not
wearing safety belts?. But unlike adults and
teenagers, their muscles and bones are not fully
developed. In many respects children are at
greater risk of serious injury in crashes than
adults.
Because children's bodies are not fully developed,
they require restraint systems especially de-
signed for their size, weight, and body structure.
Many countries and all states of the United
States and provinces of Canada have laws requir-
ing the use of approved child restraint systems
for infants and small children.
Ina frontal crash at a speed of 20-35 mph
(30-56 km/h) the forces acting on a 13-pound
(6 kg) infant will be more 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 conditions, only an appro-
priate child restraint properly used can reduce
the risk of serious injury. Child restraints, like
adult safety belts, must be used properly to be
effective. Used improperly, they can increase the
risk of serious injury in an accident.
All children, especially those 12 years and young-
er must always ride in the back seat properly re-
strained for their age and size. If you must install
a child restraint on the front passenger seat in
exceptional circumstances, be sure to read and
heed the important information and warnings
= page 254. Infants and other children who are
properly restrained in an appropriate child re-
straint that is for their size and age can benefit
from the protection that supplemental side air-
bags provide in some kinds of crashes.
For more information please see information pro-
vided by the:
278
— National Highway Traffic Safety Administration
(NHTSA), currently at : http://www.safercar.gov
(for the USA)
— Transport Canada Information Centre, currently
at: http://www.tc.gc.ca (for Canada)
Consult the child safety seat manufacturer's in-
structions in order to be sure the seat is right for
your child's size > page 282, Important safety
instructions for using child safety seats. Please
be sure to read and heed all of the important in-
formation and WARNINGS about child safety, Ad-
vanced Airbags, and the installation of child re-
straints in this chapter.
There is a lot you need to know about the Ad-
vanced Airbags in your vehicle and how they work
when infants and children in child restraints are
on the front passenger seat. Because of the large
amount of important information, we cannot re-
peat it all here. We urge you to read the detailed
information in this owner's manual about airbags
and the Advanced Airbag System in your vehicle
and the very important information about trans-
porting children on the front passenger seat.
Please be sure to heed the WARNINGS - they are
extremely important for your safety and the safe-
ty of your passengers, especially infants and
small children.

ZA 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 occupants and especially children
must be restrained properly whenever riding
in a vehicle. An unrestrained or improperly
restrained child could be injured by striking
the interior or by being ejected from the ve-
hicle during a sudden maneuver or impact.
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
provides the highest degree of protection
for infants and small children in most acci-
dent situations.
