154 Airbag sys te m
If the tota l electrical capacitance registe red
on the front passenger seat is more than that
of a typ ica l 1 year-old, but less than the
weight of a small adult, the front a irbag on
the passenger side may deploy (the
PA SSE N
GER AIR BAG OFF
li ght does not come on).
For e xample , the airbag m ay deploy if :
-a small child that is heavier than a typical 1
year-o ld child is on the front passenger seat
(regardless of whether the child is in one of
the chi ld seats listed
¢ page 175),
-a chi ld who has outgrown child restraints is
on the front passenger seat.
If the front passenger airbag is turned off, the
PASSENGER AIR BAG OFF light in the center
of the instrument panel wi ll come on and stay
on.
If the front passenger airbag deploys, the
F ederal Standard requires the airbag to meet
the " low risk" deployment criteria to help re
d uce the risk of injury through interaction
with the airbag. "Low risk" deployment occurs
in those crashes that take place at lower de
celerations as defined in the electronic control un it
¢ page 159.
Alw ays rem ember : Even though your vehicle
is equipped with Advanced Airbags, the safest
place for children is properly restrained on the
back seat . Please be sure to read the impor
tant information in the sect ions that follow
and be sure to heed a ll of the WARNINGS.
.&_ WARNING
To reduce the risk of injury when an airbag
inflates, a lways wear safety belts prope rly.
- If you are unrestrained, lean ing fo rward,
sitting sideways or out of position in any
way, your risk of injury is much higher.
- You w ill also receive serio us injuries and
cou ld even be killed if you are up against
the a irbag or too close to it when it in
flates - even with an Advanced Airbag
¢page 147.
.&_ WARNING
A child in a rearward-fac ing ch ild seat in
stalled on the front passenger seat will be
seriously injured and can be killed if the
front airbag inflates - even w ith an Ad
van ced A irbag System.
- Altho ugh the Advanced Airbag System in
your veh icle is designed to turn off the
front airbag when a rearward-facing
child restraint has been instal led on the
front passenger seat, nobody can abso
lutely g uarantee that dep loyment is im
possible in all conceivable situations that
may happen dur ing the usefu l life of your
veh icle.
- The inflating airbag will h it the ch ild seat
or infant carrier with great force and will
smash the child seat and child against
the backrest, center armrest, door, or roof.
- Always install rearward-facing ch ild re
straints on the rear seat .
- If you must install a rearward fac ing
child seat on the front passenger seat because of exceptional circumstances
and the
PASSENGER AIR BAG OFF light
does not come on and stay on, immed i
a tely insta ll the rear-facing child seat in a
rear seat ing pos ition and have the airbag
system inspected by your Audi dealer.
.&_ WARNING ,..___
If, in except iona l circumstances, you m ust
install a forward -facing child restraint on
the front passenger's seat:
- Always make sure the forward-facing
seat has been designed and certified by
its manufacturer for use on a front seat
with a passenger front and s ide a irbag.
- Never p ut the forward-facing child re
straint up against or very near the instru
ment panel.
- Always move the passenger seat into its
rearmost pos ition in the seat's fore and
aft ad justment range, as far away from
the airbag as possible, before install ing
the forward-fac ing ch ild restra int. The
-
156 Airbag system
-Repairs to the front passenger seat must
be performed by qualified and properly
trained workshop personnel.
- Never remove the front passenger or
driver seat from the vehicle.
- Never remove the upholstery from the
front passenger seat.
- Never disassemble or remove parts from
the seat or disconnect wires from it.
- Never carry sharp objects in your pockets
or put them on the seat. The capacitive
passenger detection mat in the front
passenger seat will not function properly
if it is punctured .
- Never carry things on your lap or carry
objects on the front passenger seat.
Such objects can influence the capaci
tance registered by the capacitive pas senger detection system, so that incor
rect information is provided to the airbag
control unit.
- Never store items under the front pas
senger seat. Parts of the Advanced Air
bag System under the passenger seat
could be damaged, preventing them and
the airbag system from working proper
ly.
- Never place seat covers or replacement upholstery that have not been specifical
ly approved by Audi on the front seats.
- Seat covers can prevent the Advanced
Airbag System from recognizing child re
straints or occupants on the front pas
senger seat and prevent the side airbag
in the seat backrest from deploying prop
erly .
- If a seat heater has been retrofitted or
otherwise added to the front passenger
seat, never install any child restraint sys
tem on this seat.
- Never use cushions, pillows, blankets, or similar items on the front passenger
seat. The additional layers prevent the
capacitive passenger detection system
from accurately measuring the capaci
tance of the child safety seat and/or the
person on the seat and thus keep the Ad- vanced Airbag System from working
properly.
- Never place or use any electrical device
(such as a laptop, CD player, electronic
games device, power inverter or seat
heater for child seats) on the front pas
senger seat if the device is connected to
the 12-volt socket or the cigarette light
er socket . Such devices can influence the
capacitance registered by the capacitive
passenger detection system, so that in
correct information is provided to the air
bag control unit.
- If you must use a child restraint on the
front passenger seat and the child re
straint manufacturer's instructions re
quire the use of a towel, foam cushion or
something else to properly position the
child restraint, make certain that the
PASSENGER AIR BAG OFF light comes
on and stays on whenever the child re
straint is installed on the front passen
ger seat.
- If the
PASSENGER AIR BAG OFF light
does not come on and stay on, immedi
ately install child restraint in a rear seat
ing position and have the airbag system
inspected by your Audi dealer.
.&_ WARNING ~
If the front passenger seat gets wet, dry it
immediately.
- If liquid soaks into the front passenger
seat, this can keep the airbag system
from working properly and may, for in
stance, deactivate the passenger frontal
airbag. If this happens, the
PASSENGER
AIR BAG OFF
light will come on and stay
on together with the airbag indicator
light
fl in the instrument cluster .
- If liquid is pooled on the seat, but has
not soaked in, this may also keep the air
bag system from working properly and
cause the passenger frontal airbag to be
enabled (turned on), even though there
is a properly installed child restraint sys-
tem on the seat. Wet towels or other wet
~
things on the seat cushion can have the
same effect. If the front passenger fron
tal airbag is turned on, the
PASSENGER
AIR BAG OFF
light light will go out .
How the Advanced Airbag System
components work together
The fron t Advanced Airbag System and the
side airbags supplement the protection of
fered by the front three -point safety be lts
with p retensioners and load limiters and the
adjustab le head restraints to he lp reduce the
risk of injury in a wide range of accident and
crash situat ions. Be sure to read the impor
tant information about safety and heed the
WARNINGS in this chapter .
Dep loyment of the Advanced Airbag System
and the act ivation of the safety be lt preten
sioners depend on the dece lerat ion measured
by the crash sensors and registered by the
e lectronic control un it. The amount of infla
tion of the front airbags can also be adapted to the front seat posi tion, depend ing on the
d istance between the respective front seat
and the steering whee l or instrument panel as
registe red by sensors in the seats. Crash se
verity depends on speed and deceleration as
well as the mass and stiffness of the vehicle
or object involved in the crash .
On the passenger s ide, regard less of safety
be lt use, the front passenger f ronta l airbag
will be turned off if the electrical capacitance
measured by the capac itive passenger detec
tion system on the front passenger seat is less
tha n the amount programmed in the electron
ic control unit. The front passenger fronta l air
bag will a lso be turned off if the capa cita nce
measured by the system for the front pa ssen
ger seat equa ls t hat of an infant of abo ut one
yea r of age in one o f the child seats that was
used to cert ify the Advanced Airbag System

166 Airbag system
How knee airbags work
Applies to vehicles: with knee airbags
The risk of injury to the leg area can be re
duced by fully inflated knee airbags.
Fig. 162 Inflated airbags protecting in a frontal colli·
s io n
The knee airbag system has been designed so
that the a irbags for the driver and front pas
senger deploy in certain but not all frontal
collisions.
If the front airbags deploy, the knee airbags
a lso deploy in frontal collisions when the de
ployment threshold stored in the control unit
is met .
When the system deploys, the airbags fill
with a propellant gas, and inflate between the
lower part of the instrument panel and the
driver and the lower part of the instrument
panel and the front passenger
Q page 157,
fig . 159.
Although they are not a soft pillow, they can
"cush ion" the impact and in this way they can
help to reduce the risk of injury to the lower
extremities.
All of this takes place in the blink of an eye, so
fast that many people don't even realize that
the airbags have deployed . The airbags also
inflate with a great deal of force and it is im
portant for occupant safety that nothing
should be in their way when they deploy.
Fully inflated airbags in combination with
properly worn safety belts slow down and lim
it the occupant's forward movement and help
to reduce the risk of injury. Important safety instructions on the
knee airbag system
Applies
to vehicles: with knee airbags
Airbags are only supplemental restraints. Al
ways wear safety belts correctly 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 to provide supplemental protection.
A 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 knee airbag system cannot protect
you properly if you are seated too close
to any of the airbag locations. When ad
justing their seat positions, it is impor
tant that both the driver and the front passenger keep their upper bodies and
knees at the following minimum safe
distances:
- at least 10 inches (25 cm) between the
chest and the steering wheel/instru
ment panel.
- at least 4 inches (10 cm) between the knees and the lower part of the instru
ment 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 in
creases even more should the airbag de
ploy .
- Always make sure that the knee airbag
can inflate without interference. Objects
between you and the airbag can increase
the risk of injury in an accident by inter
fering 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
Important safety instructions on the
side airbag system
Airbags are only supplemental restraints. Al
ways 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 pro
vide supplemental protection .
A WARNING
An inflating side airbag can cause serious
or fatal injury. Improperly wearing safety
belts and improper seating positions in
crease 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
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 interference.
- Never install seat covers or replace
ment 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 air bag module must always be repaired
immediately by an authorized Audi
dealer.
Airbag system 169
- 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, tel
ephone 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 be come dangerous projectiles and cause
injury when the supplemental side air
bag 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 air
bag deployment and can cause personal
injury in an accident.
- Always prevent the side airbags from be
ing damaged by heavy objects knocking
against or hitting the sides of the seat
backs.
- The airbag system can only be triggered
once. If the airbag has been triggered,
the system must be replaced by an au
thorized 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 au
thorized Audi dealer .
- If children are seated improperly, their
risk of injury increases in the case of an
accident ~
page 173, Child Safety .
-Never attempt to modify any compo
nents of the airbag system in any way .
- In a side collision, side airbags will not
function properly if sensors cannot cor rectly measure increasing air pressure in-
side the doors when air escapes through .,.. •
