Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag Sys
tem performs in a crash. For example, using
tire-r im combinations not approved by Audi,
lowering the vehicle, changing the stiffness of
the suspension, including the springs, suspen
sion 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 exam
ple, increase the force levels measured 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 meas
ured by the sensors and prevent the airbag
from deploying when it should .
The sensors in the safety belt buckle for the
d river and front passenger seat tell the elec
tronic control module if the safety belt is
latched or not. If the safety belt is being used,
the front airbag will deploy at a slightly high
er rate of vehicle deceleration than if the safe
ty belt is not being used. Therefore, in a par
ticular collision, it is possible that an airbag
will not deploy at a seating position where the safety belt is being used but will inflate at the
position where the safety belt is not being
used. It is important that nothing interfere
with the safety belt buckles so that the sen
sors can send the correct information about
safety belt use to the electronic control unit.
.&_ WARNING
Changing the vehicle 's suspension includ
ing use of unapproved tire-rim combina
tions can change Advanced Airbag per
formance and increase the risk of serious personal injury in a crash.
- Never install suspension components
that do not have the same performance
Airbag system 177
characteristics as the components origi
nally 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 con
trol module and prevent the Advanced Air bag System from working properly.
-Always make sure that nothing can inter-
fere with the safety belt buckles and that
they are not obstructed.
Knee airbags
Description of knee airbags
Applies to vehicles: wit h knee airbags
The knee airbag system can provide supple
mental protection to properly restrained
front seat occupants.
Fig. 179 Driver 's knee airbag
The driver knee airbag is in the instrument
panel underneath the steering wheel
Q fig . 179, the knee airbag for the passenger
is at about the same height in the instrument
panel underneath the glove compartment .
The knee airbag offers additional protection
to the driver's and passenger's knees and up
per and lower thigh areas and supplements
the protection provided by the safety belts.
If the front airbags deploy, the knee airbags
also deploy in frontal collisions when the de ployment threshold stored in the control unit
I),-
178 Airbag system
is met ¢ page 171, More important things to
know about front airbags.
I n addition to their normal safety function,
safety belts he lp keep the driver or front pas
senger in position in a frontal collision so that
the airbags can provide supplemental protec
tion.
The airbag system is not a s ubst itute for yo ur
safety belt . Rather, it is part of the overall oc
cupant restraint system in your vehicle. Al
ways remember that the airbag system can
only help to protect you if you are wearing
your safety belt and wear ing it properly. This
is why you shou ld always wear your safety
belt, not just because the law requires you to
do so
¢page 154, General notes .
The safety belt buckle for the driver and front
seat passenger have switches that tell the air
bag 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 slightly higher rate of decelera tion than if the belt is not be
ing used . Therefore, in a par ticu lar collision, it
is possible that an airbag will not deploy at a
seating position where the safety belt is being
used but will inflate at the pos ition where the
safety belt is not be ing used.
Remember too, airbags will deploy only once
and on ly in certain kinds of accidents -your
safety belts are a lways there to offer protec
tion in those accidents in which airbags are
not supposed to deploy or when they have al
ready deployed, fo r example whe n your veh i
cle strikes or is struck by another after the
fi rst coll is ion.
This is just one of the reasons why an airbag is
not a substitute for the safety belt . The airbag
system works most effective ly when used with
the safety belts. Therefore, always wear your
safety be lts correctly.
It is importan t to remember that while the
supplemental knee a irbag system is designed
to reduce the like lihood of serious injur ies,
o ther inj uries, for example, swel ling, bruising,
and minor abras ions and frict io n burns can a l
so occur when an airbag inflates.
The knee airbag system basically consists
of:
- The e lectronic control module
- Two inflatable ai rbags (a irbag and gas gen -
erator), one for the driver and one for the
front passenger
- The a irbag indicator light in the instr ument
panel
The knee airbag system will not deploy:
- when the ig nit ion is t urned off
- in frontal collisions when the deceleration
meas ured by the control unit is too low
- in side collisions
- in rear-end collisions
- in rollovers
- in the event of a system malfunction (warn-
ing/indicator light is on)
¢page 15.
A WARNING
--
-Safety belts and the airbag system can
only provide protection when occupants
are in the proper seating position
¢page 171.
-If the airbag ind icator light comes when
the vehicle is be ing used , have the sys
tem inspected immediate ly by you r au
thori zed A udi dealer. The airbag may not
w ork p roperly when the vehicle accelera
tion in a side collision is high enough to
de ploy the airbag . See also¢

II--
The knee airbag system has been designed so
that the airbags for the driver and front pas
senger deploy in certain but not all frontal
collis ions .
I f the front airbags deploy , the knee airbags
also deploy in fronta l collis ions when the de
p loyment threshold stored in the control unit
ist met.
When the system dep loys, the airbags fill
with a prope llant gas, and inflate between the
l ower part of the instrument panel and the
driver and the lower part of the instrument panel and the fron t passenger <=>
page 171,
fig . 17 7.
Although they are not a soft pillow, they can
cushion the impact and in this way they can

extremities .
All of this takes place in the blink of an eye, so
fast that many people don't even reali ze that
t he airbags have deployed . The airbags also
inflate w it h a great deal of force and it is im
portant for occ upant safety that not hing
should be in the ir way when they dep loy .
Fully infla ted airbags in comb ination with
properly worn safety belts slow down and lim

_.6 WARNING
An inflating knee airbag can cause ser ious
injury. Wear ing safety belts incorrectly and
improper seating positions increase the
r isk of serious personal injury and death
whenever a veh icle is being used.
A irbag system 179
-The knee a irbag system cannot p rotect
you proper ly if you a re seated too close
to any of the airbag locat ions. When ad
justing their seat pos itions, it is impor
tant that both the driver and the front passenger keep the ir upper bod ies and
knees at the following m inimum 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 in jury increases if
you lean forward or to the s ide, or if the
seat is improperly positioned and you are
not wearing yo ur safety belt . The risk i n
creases even more should the ai rbag de
ploy .
- Always ma ke sure that the knee a irbag
can inflate without inte rfe rence. Objects
between yo u and the airbag can inc rease
the risk of in jury in an accident by inte r
fering w ith the way the a irbag deploys or
by being p ushed into you as the airbag
deploys.
- Never let anybody, especia lly children
or anima ls ride in the footwell in front
of the passenge r seat. If the airbag de
ploys, th is can result in serious or fa tal
i njur ies.
- Never carry obje cts of any kind in the
footwe ll area in front of the dr iver' s or
passenger 's sea t. Bulky objects (shop
ping bags , fo r example) can interfere
with o r prevent proper deployment of
the airbag. Small objects can be
thrown through the ve hicle if the air
bag deploys and injure you or your pas
sengers .
- Make sure there are no cracks, deep
scratches or other damage in the area of
the instrument panel where the knee air
bags are located.
- If ch ildren are incorrectly seated, their
risk of injury increases in a collision

t r iggered together .
& WARNING
- Safety belts and the airbag system will
only prov ide protection when occ upants
are in the proper seating position
r:::;, page 181.
- If the airbag indicator light comes on
when the vehicle is being used, have the
system inspected immediately by your
authorized Audi dealer. The a irbag may
not wo rk properly when the vehicle ac
celeration in a side co llision is h igh
enough to activate the airbag .
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 .

184 Airbag system
How side curtain airbags work
Side curtain airbags can work together with
side airbags to help reduce the risk of head
and upper torso injuries for occupants who
are properly restrained.
Fig . 184 Ill ust ration 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

-"' ..,
-' " 18
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 or
der 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. T he side curtain airbag could in
jure you if your seating position is not proper
or upright or if items are located in the area
where the supp leme ntal side curtain airbag
inflates. This applies especially to children
r::!) page 186 .
Although they are not a soft pillow, side cur
tain airbags can "cushion" the impact and in
this way they can help to reduce the r isk of in
jury to the head and the upper part of the
body.
A fine dust may develop when the airbag de
ploys . This is quite normal and does not mean
there is a fire in the veh icle.
Important safety instructions on the
side curtain 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 do to he lp the safety belts and
airbags do their job to provide supp lemental
protection.
A WARNING
Improperly wearing safety belts and im
proper seating positions increase the risk
of serious personal injury and death when
ever 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 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
occupant hit by such a projectile can suf
fer serious injury or death

Technical Modifications.
-Do not swive l the sun visors to the side if
you have any objects clipped onto them (for examp le pens). If the airbag should
deploy, you could be injured by these ob
jects.
- 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 a irbag deployment
and can cause personal injury in an acci
dent.
- Never use hangers to hang clothing from
the hooks .
- Only use factory-installed sun shades or,
in the case of shades installed after the
veh icle leaves the factory, only Audi roll
up sunscreens may be used

186 Child Saf ety
Child Safety
Important things to
know
Introduction
The rear seat is generally the safest place in a
collision .
The physical principles of what happens when
your veh icle is in a crash app ly also to chi ldren
q page 155, What happens to occupants not
wearing safety belts? .
But unlike adults 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 deve l
oped, they require restra int systems especial
l y designed for their size , weight, and body
structure. Many countries and all states of the United States and p rovinces of Canada have
laws requiring the use of approved child re
straint systems for infants and small children .
In a 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 appropriate ch ild restraint properly
used can reduce the risk of serious injury.
Ch ild restra ints must be used properly to be
effective. Used improperly, they can increase
the risk of serious injury in an accident .
Consult the child safety seat manufactu rer's
instructions to be sure the seat is right for
your chi ld's size
q page 189, Important safe
ty instructions for using child safety seats .
Please be sure to read and heed all of the im
portant information and WARNINGS about
child safety, Advanced Airbags, and the instal lation of child restraints 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 re
straints are on the front passenger seat . Be
cause of the large amount of important infor- mation, we cannot repeat it all here
. We urge
you to read the detailed information in this
owner's manua l about airbags and the Ad
vanced Airbag System in your vehicle and the
very important information about transport
ing children on the front passenger seat .
Please be sure to heed the WARNINGS - they
are extremely important for your safety and
the safety of your passengers, especially in
fants and small children.
A WARNING
- Accident statistics have shown that chil
dren are generally safer in the rear seat
area than in the front seating position.
Always restrain any child age 12 and un
der in the rear.
- All vehicle occupants and especially chil
dren must be restrained properly when
ever riding in a vehicle. An unrestrained
or improperly restrained chi ld could be
injured by str ik ing the interior or by be
ing ejected from the vehicle dur ing a
sudden maneuver or impact. An unre
strained or improperly restrained ch ild is
also at greater risk of injury or death
through contact with an inflating airbag.
- A suitable child restraint properly instal
led and used at one of the rear seating
positions provides the highest degree of
protection for infants and small children
in most accident situations.
A WARNING
Children on the front seat of any car even
with Advanced Airbags can be seriously in
jured or even killed when an airbag in
flates . A child in a rearward-facing child
safety seat installed on the front passen
ger seat w ill be ser iously injured and can
be killed if the front airbag inflates.
- The inflating airbag will h it the child
safety seat or infant carrier with great
force and will smash the child safety seat
and child against the back rest, center
armrest or door .
- Always install rearward-facing child safe-
ty seats on the rear seat.
IJi,,,
-If you must install a rearward facing
child safety seat on the front passenger
seat in exceptional circumstances and
the
PASSENGER AIR BAG OFF light does
not come on and stay on, immediately
install the rearward-facing child safety
seat in a rear seating position and have
the airbag system inspected immediately by your authorized Audi dealer.
,& WARNING
If, in exceptional circumstances, you must
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 side airbag.
- Always follow the manufacturer's in
structions provided with the child safety
seat or carrier.
- Always move the passenger seat into its
rearmost position in the seat's fore and
aft adjustment range, as far away from
the airbag as possible before installing
the child restraint. The backrest must be adjusted to an upright position .
- Always make sure that the
PASSENGER
AIR BAG OFF
light comes on and stays
on all the time whenever the ignition is
switched on.
@ Tips
Always replace child restraints that were
installed in a vehicle during a crash. Dam
age to a child restraint that is not visible
could cause it to fail in another collision
situation.
Advanced front airbag system and children
Your vehicle is equipped with a front "Ad
vanced Airbag System" in compliance with
United States Federal Motor Vehicle Safety
Standard (FMVSS) 208 as applicable at the
time your vehicle was manufactured .
Child Safety 187
The Advanced Airbag system in your vehicle
has been certified to meet the "low-risk" re
quirements for 3- and 6-year old children on
the passenger side and small 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 "sup
pression" requirements of the Safety Stand
ard, 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 list
ed in the Standard.
Even though your vehicle is equipped with an
Advanced Airbag system, all children, espe
cially those 12 years and younger, should al
ways ride in the back seat properly restrained
for their age and size . The airbag on the pas
senger side makes the front seat a potentially
dangerous place for a child to ride . The front
seat is not the safest place for a child in a for
ward-facing child safety seat. It can be a very
dangerous place for an infant or a larger child
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
child restraint on the front passenger seat us
ing the weight-sensing mat in the seat cush
ion 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 child 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 re -
straints and for the different models of the ..,. •
