- Applies to plug-in hybrid* vehicles: In the
event of a co llision where the a irbags de­
ploy, the electrical connection to the high­
voltage battery is automatically disconnect­
ed. This prevents a short c ircuit.

rate. When the veh icle or parts of the re­
straint system incl uding airbag modules and
safety belts with pre tensioners are scrapped,
all applicable laws and regulations must be
observed. Your authorized Audi dealer is fa­
miliar with these requirements and we recom­
mend that you have your dealer perform this
service for you.
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 examp le, using tire-r im
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 suspens ion changes
can, for example, increase the force levels meas­
ured by the sensors and make the airbag system
deploy in crashes in wh ich it would not dep loy if
t he changes had no t been made. Other kinds of
changes may reduce the force levels meas ured by
the sensors and prevent the airbag from deploy­ ing when it should.
.&_ WARNING
Changing the vehicle 's s uspension incl uding
use of unapproved tire-rim combinations can
change Advanced A irbag performance and in-
Airb ag sys tem
crease the risk of serious personal injury in a
crash.
- Never install suspension components that
do not have the same performance charac­
ter istics 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
Applies to: vehicles wit h knee airbags
The knee airbag system con provide supplemen­
tal protection to properly restrained front seat
occupants.
F ig . 24 S Driver 's knee airbag
The driver knee airbag is in the instrument panel
underneath the steering
whee l¢ fig. 245, the
airbag for the passenger is at about the same
height in the instrument pane l underneath the
glove compartment.
The knee airbag offers additiona l protection to
t h e driver's and passenger's knees and upper and
lower thigh areas a nd supplements the p rotec­
t io n prov ided by the safety belts .
If the front airbags deploy, the knee airbags also
deploy in frontal collis ions when the deployment
threshold stored in the control un it is met
¢ page 2 77, More important things to know
about front airbags .
In addition to their normal safety function, safe­
ty belts help keep the dr iver or front passenger in
pos it ion in a frontal collision so t hat the airbags
can p rovide supplemental protection .

Airbag syste m
The airbag system is not a substitute for your
safety belt. Rather, it is part of the overa ll 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 because
the law requires you to do
so ¢ page 258, Gener­
al notes.
Remember too, airbags will deploy only once and
only in certain k inds of accidents
-your safety
be lts are always there to offer protection in those
accidents in wh ich airbags a re not supposed to
deploy or when they have already deployed, for
examp le when your vehicle str ikes or is struck by
another after the first collision .
This is just one of the reasons why an airbag is
not a substi tute for the safety belt. The a irbag
system works most effectively when used with
the safety belts. Therefore, a lways wear your
safety belts correct ly.
It is important to remember that whi le the sup­
p lemental knee a irbag system is des igned to re­
duce the like lihood of serious injuries, other inju ­
ries, for example, swe lling, bruising and minor
abrasions and friction burns can also occur when
an airbag inflates .
The kn ee airba g system bas ically consi sts of :
-The electronic control module
- T wo inflatab le airbags (airbag and gas genera-
t or), one for the driver and one for the front
passenger
- The airbag indicato r ligh t in the ins trument
pane l
The knee airbag system will not deploy:
-whe n the ignition is switched off
- in frontal collisions when the deceleration
measured by the control un it is too low
- in s ide collisions
- in rear -end collisions
- in rollovers
- in the event of a system ma lf u nction (wa rning/
indicator light is on)

A WARNING
-Safety belts and the airbag system can only
provide protect ion when occupants are in
the proper seat ing pos ition
¢ page 2 77 .
- If the a irbag ind icator light ¢
page 29
comes when the veh icle is being used, have
the system inspected immediately by your
author ized Audi dealer.
It is possib le that
the airbag will inflate when i t is no t sup ­
posed to , or wi ll not inflate when it should.
How knee airbags work
Applies to: vehicles with knee airbags
The risk of injury to the leg area can be reduced
by fully inflated knee airbags.
F ig . 246 Inflated a irbags protec ting in a fro nta 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 collisions .
If the front airbags deploy, the knee airbags also
deploy in frontal collisions when the dep loyment
threshold stored in the control unit is met.
When the system deploys, the a irbags f ill with a
compressed propellant gas, and inf late between
the lower part of the instrument panel and the
driver and the lower part of the instrument panel
and the front
passenger¢ page 2 77, fig. 243 .
Althoug h they are not a soft p illow, they can
"cushion" the impact and in this way they can
help to reduce the risk of injury to the lower ex­
trem ities.
A ll of th is takes p lace in the blink of an eye, so
fast that many people don 't even realize that the
airbags have deployed. The airbags a lso inflate

Important safety instructions on the knee
airbag system
A ppl ies to: ve hicles with knee 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 belts and airbags
to provide supplemental protection .
A WARNING
An inflating knee airbag can cause ser ious in­
jury. Wearing safety belts incorrectly and im­
proper seating posit ions increase the r isk of
ser ious personal inj ury and death whenever a
vehicle is being used .
- The knee airbag system cannot protect you
prope rly if you are seated too close to any of
the a irbag lo cat ions. When ad justing thei r
seat positions, it is important that both the
dr iver and the front passenger keep their
upper bodies and knees at the following
min imum safe distances:
- at least 10 inches (25 cm) between the
chest and the steer ing wheel/ins trument
panel.
- at least 4 inches (10 cm) between the
knees a nd the lower pa rt of the instru­
ment panel.
- T he risk of persona l injury inc reases if you
lean forward or to the s ide, or if the sea t is
imp roperly posi tioned and you are not wear­
ing your safety belt . The risk increases even
more should the airbag deploy .
- Always make sure tha t the knee airbag can
inflate without interference. Objects be­
tween you and the airbag can increase the risk of inj ury in an accident by inter fer ing
-
Airb ag sys tem
with the way the airbag deploys or by being
pushed into yo u as the a irbag deploys.
- Neve r let anybody, especia lly children or
anima ls r ide in the footwell in front of the
passenger seat. If the airbag deploys, this
can result in serious or fatal i njuries.
- Neve r carry objects of any kind in the foot­
well a rea in front of the driver's or pas­
senger 's seat . Bulky objects (shopp ing
bags, for example) can i nterfere 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 hild ren are incorrectly seated, their risk
of injury increases in

The airbag system is monito red elect ronically to
make certa in that it is functioning properly at all
times. Each time you switch on the ign ition, the
airbag system indicator light will come on for a
few seconds (self diagnostics) .
The s ide a irba g system supplements the safety
be lts and can help to reduce the risk of injury to
the driver's, front and rear* passenger 's upper
torso on the side of the vehicle that is struck in a
side co llision . The airbag dep loys only in side im­
pacts and on ly when the vehicle acceleration reg­
istered by the control unit is h igh enough . If this
rate is below the reference value programmed in ­
to the control un it, the side airbags w ill not be
tr iggered , even though the car may be bad ly
damaged as a result of the collision.
It is not pos­
sib le to define an a irbag tr igger ing range that
will cover every possible ang le of impact , since
the circumstances wi ll vary considerably between
one co llision and another. Important factors in ­
clude, for example , the nature (hard or soft) of
the impacting object, the angle of impact, vehicle
speed, etc.
¢ page 287, Important safety in­
structions on the side airbag system .
Aside from their normal safety function, safety
belts work to help keep the driver or front pas­

Applies to: ve hicles w ith s ide curta in a irbags
Side curtain airbags con work together with side
airbags to help reduce the risk of head and upper
torso injuries for occupants who ore properly re­
strained.
F ig. 251 Illustration of principle: Inflated side curta in air ­
bags on the left s ide (examp le}
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
c::;, fig. 251.
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 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 curta in a irbag could injure you if your
seating position is not proper or upright or if
items are located in the area where the supp le­

Child safety
Child safety
Important information
Introduction
The rear seat is generally the safest place in a
collision .
The physical principles of what happens when
your vehicle is in a crash apply also to children
¢ page 259, What happens to occupants not
wearing safety belts? .
But unlike adults and
teenagers, their muscles and bones are not fully
developed. In many respects children are at
g reater r isk of serious injury in crashes than
adults .
Because children's bodies are not fully devel­
oped, they require restraint systems especially
des igned for their size, weight, and body struc­
ture. Many countries and all states of the United
States and provinces of Canada have laws requir­
ing the use of approved child restraint 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 appro­
priate child restraint properly used can reduce
the risk of serious injury . Child restra ints, like
adu lt safety belts, must be used properly to be
effect ive. Used improperly, they can increase the
risk of serious injury in an acc ident.
All ch ildren, especially those 12 years and young­
er must always ride in the back seat properly re­
stra ined for their age and size. If you must insta ll
a child restraint on the front passenger seat in
exceptional circumstances, be sure to read and
heed the important information and warnings
¢ page 268. Infants and other children who are
properly restrained in an appropriate child re­
straint that is for their si ze and age can benefit
from the protection that supplemental side air­
bags provide in some kinds of crashes .
For more information please see information

(NHTSA), currently at: http :/ /www.safe­
rcar.gov (for the USA)
-Transport Canada Information Centre, current-

Consult the child safety seat manufacturer's in­
structions in order to be sure the seat is right fo r
your chi ld's
size ¢ page 296, Important safety
instructions for using child safety seats .
Please
be sure to read and heed all of the important in­
formation and WARNINGS about child safety,
Advanced Airbags, and the installation of child
restra ints 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 restraints are
on the front passenger seat . Because of the large
amount of important informat ion , we cannot re­
peat it all here. We urge you to read the detailed
i nformation in this owner's manual about airbags
and the Advanced Airbag System in your vehicle
and the very important information about trans­
porting children on the front passenger seat.
Please be sure to heed the WARNINGS -they are
extremely important for your safety and the safe­
ty of your passengers, especially infants and
small children .
A WARNING
-Accident statistics have shown that children
are generally safer in the rear seat area than
in the front seat ing pos ition. Always restrain
any child age 12 and under in the rear.
-All vehicle occupants and especially children
must be restra ined prope rly whenever rid ing
in a vehicle. An un restrained or improperly
restrained child could be injured by striking
the interior or by being ejected from the ve­
hicle during a sudden maneuver or impact.
An unrestrained or improperly restrained
child is a lso at greater risk of injury or death
through contact w ith an inflating airbag.
-A suitable ch ild restraint properly installed
and used at one of the rear seating positions
provides the highest degree of protect ion
for infants and small children in most acc i­
dent situat ions.
