combinations not approved by Audi, lowering the
vehicle, changing the stiffness of the suspension,
including the springs, suspension struts, shock
absorbers etc. can change the forces that are
measured by the airbag sensors and sent to the
electronic control unit. Some suspension changes
can, for example, increase the force levels meas
ured by the sensors and make the airbag system
deploy in crashes in which it would not deploy if
the changes had not been made. Other kinds of
changes may reduce the force levels measured by
the sensors and prevent the airbag from deploy
ing when it should.
_&. WARNING
Changing the vehicle's suspension including
use
of unapproved tire-rim combinations can
change Advanced Airbag performance and in
crease the risk of serious personal injury in a
crash.
-Never install suspension components that
do not have the same performance charac
teristics as the components originally instal
led on your vehicle.
- Never use tire-rim
combinations that have
not been approved by Audi.
Knee airbags
Description of knee airbags
The knee airbag system can provide supplemen
tal protection to properly restrained front
seat
occupants.
Fig. 159 Driver's knee airbag
The driver knee airbag is in the instrument panel
underneath the steering wheel Q fig. 159, the
airbag for the passenger is at about the same
204
height in the instrument panel underneath the
glove compartment.
The knee airbag offers additional protection to
the driver's and passenger's knees and upper and
lower thigh areas and supplements the protec
tion provided by the safety belts.
If the front airbags deploy, the knee airbags also
deploy
in frontal collisions when the deployment
threshold stored in the control unit is met
Qpage 197, More important things to know
about front airbags.
In addition to their normal safety function, safe
ty belts help keep the driver or front passenger in
position in a frontal collision so that the airbags
can provide
supplemental 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 airbag system can only help to
protect you if you are wearing your safety belt
and wearing it properly. This is why you should
always wear your safety belt, not just be ca use
t h e law requires you
to do so~ page 180, Gener
al notes .
Remember too, airbags will deploy only once and
only in certain kinds of accidents -your safety
belts are always 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 vehicle 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 belt. The airbag
system works most effectively when used with
the safety belts. Therefore, always wear your
safety belts correctly.
It is important to remember that while the sup
plemental knee airbag system is designed to re
duce the likelihood of serious injuries, other inju
ries, for example, swelling, bruising and minor
abrasions and friction burns can also occur when
an airbag inflates.
The knee airbag system basically consists of:
-The electronic control module .,.
Downloaded from www.Manualslib.com manuals search engine Airbag system
-at least 10 in (25 cm) between the chest
and the steering wheel/instrument panel.
-
at least 4 in (10 cm) between the knees
and the lower part of the instrument pan
el.
- 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 wear
ing your safety belt. The risk increases even
more should the airbag deploy.
- Always
make sure that the knee airbag can
inflate without interference. Objects be
tween you 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.
- Never
let anybody, especially children or
animals ride in the footwell in front of the
passenger seat. If the airbag deploys, this
can result in serious or fatal injuries.
- Never carry
objects of any kind in the foot
well area in front of the driver's or pas
senger's seat. Bulky objects (shopping
bags, for example) can interfere with or
prevent proper deployment 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 scratch
es or other damage in the area of the instru
ment panel where the knee airbags are lo
cated.
-If children are incorrectly seated, their risk
of injury increases in a collision

Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained front
seat occu
pants .
Fig . 161 Side airbag location in the driver's seat
The side airbags are located in the sides of the
front seat backrests Q fig. 161 facing the doors.
They
are identified by the word "AIRBAG".
The side airbags installed for the front seating
positions have been designed and certified to
help reduce the risk of injury that can be caused
by airbags when they inflate, particularly when
the occupant sitting next to it is not seated prop
erly. The
side airbag for the front passenger seat
can be used with properly installed child re
straints. Please be sure to read the important in
formation and warnings whenever using a child
restraint in a vehicle: Safety belts Q page 180,
Airbag system Q page 188, Child safety
¢page 212.
The side airbag syste m b asica lly consist s o f:
-
the electronic 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 overhead con
sole.
The airbag system is monitored electronically to
make certain that it is functioning properly at all
times. Each time you turn on the ignition, the air
bag system indicator light will come on for a few
seconds (self diagnostics). Iii>

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 col
lision. The
airbag deploys in side impacts and on
ly when the vehicle 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 air
bag
triggering range that will cover every possi
ble
angle of impact, since the circumstances will
vary considerably
between one collision and an
other. Important factors include, for example,
the nature (hard or soft) of the impacting object,
the angle of impact, vehicle speed, etc.
Q page 208, Important safety instructions 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 Qpage 180, General notes.
It is important to remember that while the sup
plemental side a irbag system is designed to re
duce the lik eli hood 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 -
Airbag system
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 a irbags, side
curtain airbags and side airbags may be triggered
together.
A WARNING
--Safety belts and the airbag system will only
provide protection
when occupants are in
the proper seating position Q page 208.
-If the airbag indicator light Q page 15
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.

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 212, Child safety.
-Never attempt to modify any components of
the airbag system in any way.
-
In a side collision, side airbags will not func
tion properly if sensors cannot correctly
measure increasing air pressure inside the
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 re
moved from the inside door panel and the
openings they leave have not been proper
ly 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

Side curtain airbags
Description of side curtain airbags
The side curtain airbag system can provide sup
plemental protection to properly restrained oc
cupants.
Fig. 163 Side curtain airbags, driver's side: side curtain air
bag locat ion
The side curtain airbags are located on both sides
of the interior above the front and rear side win
dows~ fig. 163. They are identified by the word
"AIRBAG" on the windshield frame and the cen
ter roof pillar .
The
side curtain airbags contain features that
provide ejection mitigation to help prevent vehi
cle occupants or parts of their bodies from being
completely or partially ejected from the vehicle
interior in certain side impacts and vehicle roll
overs.
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. The
side
curtain airbag inflates in side impacts and
only when the vehicle acceleration registered by
the control unit is high enough. If this rate is be
low the reference value programmed into the
control unit, the side curtain airbag will not be
triggered, even though the car may be badly
damaged as a resu lt 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 collis ion and another. Important factors in

A WARNING
-Safety belts and the airbag system will only
provide
protection when occupants are in
the proper seating position Q page 44,
Seats and storage.
-If the airbag indicator light Q page 15
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 side curtain airbags work
Side curtain airbags can work together with side
airbags to help reduce
the risk of head and upper
t orso injuries for occupants who are properly re
strained.
Fig. 164 Illustration of principle: Inflated side curtain air
bags on
the left side
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 Q fig. 164.
When the system is triggered, the s ide curtai n
airbag
is filled with propellant gas and breaks
th rough 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 Qpage 212.
