Airbag system
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 collis ion .
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 des igned to re
duce the likelihood of serious injuries, other inju
ries, for example, swelling , bruising and minor
ab rasions and friction burns can also occur when
an airbag inflates.
The knee airbag system basically consists of:
-The electronic control module
- Two inflatable airbags (airbag and gas genera-
tor), one for the driver and one for the front
passenger
- The airbag indicator light in the instrument
panel
The knee airbag system will not deploy :
-when the ignition is switched off
- in frontal collisions when the deceleration
measured by the control unit is too low
- in side collisions
- in rear-end collisions
- in rollovers
- in the event of a system malfunct ion (warning/
indicator light is on) ¢

_&, WARNING
-Safety belts and the airbag system can only
provide protection when occupants are in
the proper seating position¢
page 144.
-If the airbag indicator light ~ page 17
comes when the vehicle is be ing used, have
the system inspected immediate ly by your
authorized Audi dealer. It is possible that
the airbag will inf late when it is not sup
posed to, or will not inflate when it should.

How knee airbags work
Applies to : vehicles wit h knee airbags
The risk of injury to the leg area can be reduced
by fully inflated knee airbags .
Fig. 159 Inflated airbags protec ting in a fronta l co llis io n
The knee airbag system has been designed so
that the airbags for the driver and front passen
ger dep loy in certain but not all frontal co llisions.
If the front airbags deploy, the knee airbags also
deploy in frontal collisions when the deployment
threshold stored in the control unit is met.
When the system deploys, the airbags fi ll with a
prope llant gas , and infla te between the lower
part of the instrument panel and the d river and
the lower part of the instrument panel and the
front passenger ¢
page 144, fig. 156.
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 lower ex
tremities.
All of th is takes pla ce 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 important for
occupant safety that nothing should be in their
way when they deploy .
Fully inflated airbags in combination with proper
ly worn safety be lts s low down and limit the oc
cupant's forward movement and help to reduce
the risk of injury.
Important safety instructions on the knee
airbag system
App lies to: ve hicles with k nee a irbags
Airbags are only supplemental restraints. Always
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 be lts and airbags
to provide supplemen tal protection .
A WARNING
An inflating knee airbag can cause serious in
jury . Wearing safety belts incorrectly and im
proper seating positions increase the risk of
ser ious 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 a irbag locat ions. When adjusting their
seat positions , it is important that both the
driver and the front passenger keep their
upper bod ies a nd knees at the followi ng
min imum safe distances :
- at least 10 inches (25 cm) between the
chest and the steering wheel/instrument
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 s ide, or if the seat is
improperly positioned and you are not wear
ing your safety belt . The risk increases even
more should the a irbag deploy.
- Always make sure that the knee airbag can
inflate without inte rference . Objects be
tween you and the a irbag can increase the
risk of i nju ry in an accident by interfer ing
w ith the way t he a irbag deploys o r by being
pushed into you as the airbag deploys .
- Never let anybody, especially chi ldren or
animals ride in the footwell in front of the
passe nger seat. If the airbag deploys, this
can resu lt in se rious or fatal injur ies.
- Never carry objects of any k ind in the foot
well area in front of the driver's or pas
senger's seat . Bu lky objects (shopping
-
Airb ag sys tem
bags, for example) can interfere with or
prevent proper dep loyment 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 c hildren are incorrectly seated, their risk
of injury inc reases in a coll is ion

Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained occupants.
Fi g. 160 Side airb ag locat io n in t he drive r's sea t
The side airbags are located in the s ides of the
front seat backrests ¢
fig. 160 and the rear back
rest fac ing the doors . They a re identified by the
word "AIRBAG".
The side airbags installed for the fro nt seating
pos it ions have been des igned and certified to
help reduce the risk of inju ry that can be caused
by a irbags when they inflate, pa rtic ularly when
t h e occ upant sitting next to it is not seated prop

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 pos
sib le to define an airbag tr iggering range that
will cover every possib le angle of impact, since
the circumstances will vary considerably between
one collision and another. Important facto rs in

The a irbag sys tem is not a s ubst itute for yo ur
safety bel t. Rat her, it is part of the overa ll occu
pant restraint system in your veh icle. Always re
member that the airbag system can only help to
protect yo u 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 requires you to do so
c:::, page 127, General information .
It is important to remember that while the s ide
curta in airbag system is designed to help reduce
the likelihood of serious injuries, other injuries,
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 cert ain kin ds of ac ciden ts -you r safe ty belts are

Advanced front airbag system and children
Your vehicle is equipped with a front "Advanced
Airbag System" in compliance with United States
F edera l Motor Vehicle Safety Standard ( FMVSS)
208, as well as Canada Motor Vehicle Safety
Standard (CMVSS) 208 as applicable at the time
your veh icle was manufactured.
The Advanced Airbag system in your vehicle has
been certified to meet the "low-risk" require
ments for 3- and 6-year old children on the pas
senger 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
"s uppress ion " req uirements of the Safety Stand
ard, to turn off the front airbag for infants up to
12 months who are restrained on the front pas
senger seat in child restraints that are listed in
the Standard.
E ven though your vehicle is equipped with an Ad ·
vanced Airbag system, all children, especially
those 12 years and younger, should always ride
in the back seat properly restrained for their age
and size. The airbag on the passenger side makes
the front seat a potentially dangerous place for a
child to r ide. The front seat is not the safest place
for a child in a forward-facing child safety seat .
It
can be a very dangerous place for an infant or a
la rger child in a rearward-facing seat.
The vehicle's Advanced A irbag System has a ca
pac itive passenger detect io n system in the front
passenger seat cush ion that can detect the pres
ence of a baby or a child in a child restraint sys
tem on this seat .
The capacit ive passenger detection system regis
ters the changes that result in an electrical field
when a child, a child restraint, and a baby blanket
are on the front passenge r seat. The change in
the measured capacitance due to the presence of
a child, a child restraint, and a baby blanket on
the front passenger seat is related to the child restraint system resting on the seat. The meas
ured capacitance of a child restraint system var-

ies depending on the type of system and specific
make and mode l.
T he elect rical capacitance of the various types,
makes, and models of child restra ints specified
by the U.S .National Highway Traff ic Safety Ad
ministration (NHTSA) in the relevant safety
standard are stored in the Advanced Airbag Sys
tem control unit together with the capacitances
typ ical of infants and a 1-year old child. When a
child restraint is used on the front passenger
seat w it h a typical 1 year-old infant, the Ad
vanced Airbag System compares the capacitance measured by the capacitive passenge r detection
system with the data stored in the electronic con
t rol unit.
Child restraints and Advanced front airbag
system
Regardless of the ch ild restraint that you use,
make sure that it has been certified to meet Safe
ty Standards and has been cert ified by its manu
facturer for use w ith an airbag . Always be sure
that the child restraint is properly installed at
one of the rear seating positions. If in exception
al circumstances you must use it on the front
passenger seat, carefully read all of the informa
tion on child safety and Advanced Airbags and heed all of the applicable WARNINGS . Make cer
tain that the chi ld and child restraint are correct
ly recognized by the capac itive passenger detec
t ion system in the front passenger seat, that the
front passenger a irbag is turned off, and that the
airbag status is always correctly s ignaled by the
PASSENGER AIR BAG OFF light .
Many types and models of child restra ints have
been available over the years, new models are in
troduced regularly incorporating new and im
proved designs and older models are taken out of
production. Child restra ints are no t standardized.
Child restraints of the same type typically have
different weights and sizes and different "foot
prints", the size and shape of the bottom of the
chi ld restraint that sits on the seat, when they
are installed on a vehicle seat. These differences
make it virtually impossib le to certify compliance
with the requirements for advanced a irbags w ith
each and every child restra int that has ever been ..,.
