1 7 0 Airbag system
How knee airbags work
The risk of injury to the leg area can be re
duced by fully inflated knee airbags.
Fig . 170 Inflated airbags protect ing in a frontal coll i
sio 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
collis ions ..
If the front airbags deploy, the knee airbags
also deploy i n 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
9 page 162,
fig. 167.
Although they a re not a soft pillow, they can
"cush ion " the impact and in this way they can
he lp 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 . T he ai rbags also
inflate with a great deal of force and it is im
po rtan t for occupant sa fety that not hing
should be in their way when they deploy.
Fu lly inflated airbags in combination with
properly worn safety bel ts slow down and lim
it the oc cupant's forwa rd movement and help
to reduce the risk of injury. Important safety instructions on the
knee airbag system
Airbags are only supplemental restraints
. Al
ways wear safety belts correctly and ride in a
proper seating position.
The re is a lot that you and your passengers
must know and do to he lp the sa fety belts and
airbags to prov ide supplemen ta l protect ion.
A WARNING ~
An inflat ing knee a irbag can cause serio us
i njury . Wearing safety belts incorrectly and
improper seating positions increase the
risk of ser ious persona l injury and death
whenever a vehicle is being used.
- The knee airbag system cannot protect
you properly if you a re seated too close
to any of the airbag locations. 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
d istances:
- 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 a irbag de
p loy .
- Always make s ure that the knee airbag
can inf late without inte rfe rence. Objects
between yo u and the airbag can increase
the risk of injury in an accident by inter
fering w ith the way the airbag deploys or
by being pushed into you as the airbag
deploys.
- Never let anybody, espec ia lly children
o r anima ls ride in the footwell in front
of the passenger seat. If the airbag de
ploys, this can result in serious or fatal
injuries.
- Never carry objects of any kind in the
footwell area in front of the driver's or passenger's seat. Bulky objects (shop
ping bags, for example) can interfere
with or prevent proper deployment of
the airbag. Small objects can be
thrown through the vehicle 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 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 occupants.
---
Fig. 171 Side airbag location in the driver's seat
The side airbags are located in the sides of the
front seat backrests
¢fig. 171 and the rear
backrest facing the doors. They are identified
bytheword "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
Airbag system 1 71
- the airbag warning light in the instrument
cluster.
The airbag system is monitored electronically
to make certain that it is functioning properly
at all times. Each time you switch on the igni
tion, the airbag system indicator light will
come on for a few seconds (self diagnostics).
The side airbag system supplements the safe
ty belts and can help to reduce the risk of in
jury to the driver's, front and rear passenger's
upper torso on the side of the vehicle that is
struck in a side collision. The airbag deploys
only in side impacts and only when the vehicle
acceleration registered by the control unit is
high enough.
If this rate is below the refer
ence value programmed into the control unit,
the side airbags will not be triggered, even
though the car may be badly damaged as a re
sult of the collision.
It is not possible to de
fine an airbag triggering range that will cover every possible angle of impact, since the cir
cumstances will vary considerably between
one collision and another. Important factors include, for example, the nature (hard or soft)
of the impacting object, the angle of impact,
vehicle speed, etc. ¢
page 173, Important
safety instructions on the side airbag system.
Aside from their normal safety function, safe
ty belts work to help keep the driver or front
passenger 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 oc
cupant restraint system in your vehicle. Al
ways remember 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 reason why you should always wear
your safety belts, not just because the law re
quires you to do so¢
page 145, General
notes.
It is important to remember that while the
supplemental side airbag system is designed
to reduce the likelihood of serious injuries,
other injuries, for example, swelling, bruising,
IIJ>,
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 173
- 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 177, 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 .,.. •

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
~ page 146, What happens to occupants not
wearing safety belts? .
But unlike adults and
teenagers, their muscles and bones are not
fu lly developed. In many respects children are
at greater risk of serious injury in crashes than
adu lts.
Because children's bod ies are not fully deve l
oped, they require restraint systems especial ly designed for their size, weight, and body
structure. Many countries and all states of the
United States and provinces of Canada have
laws requiring the use of approved child re
straint systems for infants and small children .
In a fronta l crash at a speed of 20 -35 mph
(30-56 km/h) the forces acting on a 13-pound
(6 kg) infant w ill be more than 20 t imes the
weight of the child . This means the weight of
the child would suddenly be more than
260 pounds (120 kg). Under these conditions,
on ly an appropriate chi ld restraint properly
used can reduce the risk of ser ious injury .
Child restraints, like adult safety belts, must
be used properly to be effective. Used improp
erly, they can increase the risk of serious in
jury in an accident.
Consult the child safety seat manufacturer's
instructions in order to be sure the seat is
right for your chi ld's size ~
page 180, Impor
tant safety instructions for using child safety
seats.
Please be sure to read and heed all of
the important information and WARNINGS
about ch ild safety, Advanced A irbags, and the
installation 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-
Child Sa fet y 177
straints are on the front passenger seat . Be
cause of the large amount of important infor
mation, we cannot repeat it a ll here . We urge
you to read the detailed information in this owner's manual 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 chi ldren .
.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 ikin g the interior or by be
ing ejected from the vehicle during a
sudden maneuver or impact. An un re
strained or improper ly restrained chi ld is
also at greater risk of injury or death
through contact with an inflating airbag.
- A suitable chi ld 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 ser iously in
jured or even killed when an a irbag in
flates. A child in a rearward-fac ing ch ild
safety seat installed on the front passen
ger seat will 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 backrest, center
armrest, or door.
•
•
178 Child Safety
-Always install rear-facing child safety
seats on the rear seat.
- 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 rear-facing child safety seat in
a rear seating position and have the air
bag system inspected immediately by
your 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.
(D 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.
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 th e
driver side. The low ris k deployment criteria
are intended to reduce the risk of injury
through interact ion with the airbag t hat 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
same kind of child restraint offered by child restra int manufacturers.
The weight ranges for the individual types, makes and mode ls of ch ild restra ints that the
NHTSA has specified in the Safety Standard
together with the we ight ranges of typical in
fants and typical 1 year -old child have been
stored in the control unit of the Advanced A ir
bag System . When a chi ld restraint is being
used on the front passenge r seat with a typi
cal 1 year -old ch ild, the A dvanced Airbag Sys
tem compares the we ight measured by the
weight sensing mat with the information stor
ed in the electronic control unit.
The electron ic contro l unit al so registers the
tension on the front passenger safety be lt.
The tension on the safety be lt for the front
passenger seat will be different for an adult
who is properly using the safety belt as com
pared to the tension on the be lt when it is
used to attach a child restraint to the seat.
T he sensor below the latch for the safety belt
for the front seat passenger measures the
tension on the belt . T he input from this sen
sor is t hen used w ith the we ight to "decide",
whether there is a ch ild restraint with a typ ica l
1 year-o ld child on the front passenger seat
and whether or not the airbag must be turned
off .
Child restraints and Advanced Airbags
Regard less of the child restraint that you use,
make sure that it has been certified to meet
United States Federal Motor Vehicle Safety
Standards and has been certified by its manu
facturer for use with an airbag . Always be sure
that the chi ld restraint is p roperly instal led at
one of the rear seat ing pos itions . If in excep
tional ci rcumstances you must use it on the
front passenger seat, carefu lly read all of the
information on child safety and Advanced Air
bags and heed a ll of the app licable WARN
INGS. Make certain that the child restraint is
correctly recognized by the weight-sensing
Child Sa fet y 1 79
mat inside the front passenger seat, that the
front passenger airbag is turned off and that
the a irbag status is always correct ly signaled
by the
PAS SENGE R AIR BAG OFF light.
Many types and models of child restraints
have been available over t he years, new mod
els are introduced regu larly incorporating new
and improved des igns and o lder models are
taken out of product ion. Ch ild restraints are
not standard ized . Child restraints of the same
type typ ically have d ifferent weights and sizes
and different 'footpr ints,' the size and shape
of the bottom of the ch ild restrai nt that sits
o n the seat, when they a re insta lled on a veh i
cle seat. These diffe rences make it v irtually
impossible to certify compliance with the re
quirements for advanced airbags with each
and every ch ild restraint that has ever been
sold in the past or will be sold over the course
of the useful life of your veh icle.
For this reason, the United States National
Highway Traffic Safety Adm inistrat ion has
published a list of spec ific type, makes and
models of child restraints that must be used
to certify comp liance of the Advanced Airbag
System in your veh icle with the suppression
requirements of Federal Motor Vehicle Safety
Standa rd 208. These chi ld restraints are :

T o reduce the risk of serious injury, make
sure that the
PASSENGER A IR BAG OFF
light comes on and stays on whenever a
child restraint is installed on the front pas
senger seat and the ignition is switched
on.
- Take the child restraint off the front pas
senger seat and install it properly at one
of the rear seat positions if the
PASSEN
GER AIR BAG OFF
light does not stay on. -
Have the airbag system inspected by
your author ized Audi dealer immed iate
ly.
@ Tips
The child seats listed in categories A to C have been statically tested by Audi on ly for
the Advanced A irbag function.
Important safety instructions for using
child safety seats
Correct use of child safety seats substantially
reduces the risk of injury in an accident!
As the driver, you are responsib le for the safe
ty of everybody in the veh icle, especially ch il
dren:
.. Always use the right chi ld safety seat for
each child and always use it properly
¢page 183.
.. Always carefully follow the child safety seat
manufacturer's instruct ions on how to route
the safety belt properly through the ch ild
safety seat .
.. When using the vehicle safety belt to install
a child safety seat, you m ust first a ctivate
the convertib le locking retractor on the
safety belt to prevent the child safety seat
from moving
¢ page 187.
.. Push the ch ild safety seat down with your
full weight to get the safety belt really tight so that the seat cannot move forward or
sideways more than one inch (2 .5 cm) .
.,. If a strap or tether is be ing used to tie the
child safety seat to the front passenger
seat , m ake sure tha t it is not so tight that i t
causes the weight-sensing ma t to measure
more weight than is act ually on the seat.
.. Sec ure unused safety belts on the rear seat
¢ page 182.
Always remember : Even though your vehicle is
equipped with an Advanced Airbag system, all
children, especially those 12 years and young
er, shou ld always r ide in the back seat proper-
ly restrained for their age and size . .,.
A WARNING
1
Not using a child safety seat, using the
wrong child safety seat or improperly in
stalling a child restraint increases the risk
of serious personal injury and death .
-All vehicle occupants and especially chil dren must always be restrained properly
whenever riding in a vehicle.
- An unrestrained or improperly restrain
ed child can be injured or killed by be
ing thrown against the inside of the ve
hicle or by being ejected from it during
a sudden maneuver or impact.
- An unrestrained or improperly restrain
ed child is at much greater risk of injury
or death by being struck by an inflating
airbag.
- Commercially available child safety seats
are required to comply with U.S. Federal
Motor Vehicle Safety Standard (FMVSS)
213 (in Canada CMVSS 213).
- When buying a child restraint, select
one that fits your child and the vehicle.
- Only use child restraint systems that
fully contact the flat portion of the
seat cushion. The child restraint must
not tip or lean to either side. Audi does
not recommend using child safety
seats that rest on legs or tube -like
frames . They do not provide adequate
contact with the seat.
-Always heed all legal requirements per
taining to the installation and use of
child safety seats and carefully follow
the instructions provided by the manu
facturer of the seat you are using.
- Never allow children under 57 inches
(1.45 meters) to wear a normal safety
belt. They must always be restrained by a
proper child restraint system. Otherwise,
they could sustain injuries to the abdo
men and neck areas during sudden brak
ing maneuvers or accidents.
- Never let more than one child occupy a
child safety seat .
Child Safety 181
-Never let babies or older children ride in
a vehicle while sitting on the lap of an
other passenger.
- Holding a child in your arms is never a
substitute for a child restraint system .
- The strongest person could not hold
the child with the forces that exist in
an accident. The child will strike the in
terior of the vehicle and can also be
struck by the passenger.
- The child and the passenger can also
injure each other in an accident.
- Never install rear-facing child safety
seats or infant carriers on the front pas
senger seat. A child will be seriously in
jured and can be killed when the passen
ger airbag inflates -even with an Ad
vanced Airbag System .
- The inflating airbag will hit the child
safety seat or infant carrier with great
force and will smash the child safety seat
and child against the backrest, center
armrest, door or roof .
-Always install rear-facing child safety
seats or infant carriers on the rear seat .
- Forward-facing child safety seats instal
led on the front passenger 's seat can in
terfere with the airbag when it inflates
and cause serious injury to the child.
Al
ways install forward-facing child safety
seats on the rear seat .
- If exceptional circumstances require the
use of a forward-facing child restraint on
the front passenger's seat, the child's
safety and well-being require that the
following special precautions be taken:
- Make sure the forward-facing seat has
been designed and certified by its man
ufacturer for use on a front seat with a
passenger front and side airbag.
- Always carefully follow the manufac
turer's instructions provided with the
child safety seat or carrier.
- Always move the front passenger seat
into the rearmost position of the pas
senger seat's fore and aft adjustment range, and as far away from the airbag •
