Airbag system


passenger detection system from accurately
measuring the capacitance of the child safe-
ty seat and/or the person on the seat and
thus keep the Advanced 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 passenger seat
if the device is connected to the 12-volt
socket or the cigarette lighter socket. Such
devices can influence the capacitance regis-
tered by the capacitive passenger detection
system, so that incorrect information is pro-
vided to the airbag control unit.
— If you must use a child restraint on the front
passenger seat and the child restraint man-
ufacturer's instructions require 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 restraint is installed on the front pas-
senger seat.
— If the PASSENGER AIR BAG OFF light does
not come on and stay on, immediately in-
stall child restraint in a rear seating position
and have the airbag system inspected by
your Audi dealer.


Z\ WARNING
If the front passenger seat gets wet, dry it im-
mediately.
— If liquid soaks into the front passenger seat,
this can keep the airbag system from work-
ing properly and may, for instance, deacti-
vate 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 Ea in the instru-
ment cluster.
— If liquid is pooled on the seat, but has not
soaked in, this may also keep the airbag sys-
tem from working properly and cause the
passenger frontal airbag to be enabled
(turned on), even though there is a properly
installed child restraint system on the seat.
Wet towels or other wet things on the seat

cushion can have the same effect. If the
front passenger frontal airbag is turned on,
the PASSENGER AIR BAG OFF light will turn
off.

How the Advanced Airbag System
components work together
The front Advanced Airbag System and the side
airbags supplement the protection offered by the
front three-point safety belts and the adjustable
head restraints* to help reduce the risk of injury
in a wide range of accident and crash situations.
Be sure to read the important information about
safety and heed the WARNINGS in this chapter.
Deployment of the Advanced Airbag System and
the activation of the safety belt pretensioners de-
pend on the deceleration measured by the crash
sensors and registered by the electronic control
unit. Crash severity depends on speed and decel-
eration as well as the mass and stiffness of the
vehicle or object involved in the crash.
On the passenger side, regardless of safety belt
use, the front passenger frontal airbag will be
turned off if the electrical capacitance measured
by the capacitive passenger detection system on
the front passenger seat is less than the amount
programmed in the electronic control unit. The
front passenger frontal airbag will also be turned
off if the capacitance measured by the system for
the front passenger seat equals that of an infant
of about one year of age in one of the child seats
that was used to certify the Advanced Airbag Sys-
tem under Federal Motor Vehicle Safety Standard
208. The PASSENGER AIR BAG OFF light comes
on and stays on to tell you when the front Ad-
vanced Airbag System on the passenger side has
been turned off > page 265.

ZA WARNING
To reduce the risk of injury when an airbag in-
flates, always wear safety belts properly.
— If you are unrestrained, leaning forward, sit-
ting sideways or out of position in any way,
your risk of injury is much higher.
— You will also receive serious injuries and

could even be killed if you are up against the

Fig. 217 Inflated front airbags
Safety belts are important to help keep front seat
occupants in the proper seated position so that
airbags can unfold properly and provide supple-
mental protection in a frontal collision.
The front airbags are designed to provide addi-
tional protection for the chest and face of the
driver and the front seat passenger when:
— safety belts are worn properly,
— the seats have been positioned so that the oc-
cupant is properly seated
—and for adjustable head restraints: the head re-
straints have been properly adjusted.
Because airbags inflate in the blink of an eye with
great force, things you have on your lap or have
placed on the seat could become dangerous pro-
jectiles, and be pushed into you if the airbag in-
flates.
When an airbag deploys, fine dust is released.
This is normal and is not caused by a fire in the
vehicle. This dust is made up mostly of a powder
used to lubricate the airbags as they deploy. It
could irritate skin.
It is important to remember that while the sup-
plemental airbag system is designed to reduce
the likelihood of serious injuries, other injuries,
for example swelling, bruising and minor abra-
sions, can also happen when airbags inflate. Air-
bags do not protect the arms or the lower parts
of the body. Front airbags supplement the three-
point safety belts only in some frontal collisions
in which the vehicle deceleration is high enough
to deploy the airbags.
Front airbags will not deploy:
— if the ignition is switched off when a crash oc-
curs,
— in side collisions,
—in rear-end collisions,
—in rollovers,
— when the crash deceleration measured by the
airbag system is less than the minimum thresh-
old needed for airbag deployment as registered
by the electronic control unit.
The front passenger airbag also will not
deploy:
— when the front passenger seat is not occupied,
— when the electrical capacitance measured by
the capacitive passenger detection system for
the front passenger seat indicates that the pas-
senger side frontal airbag must be switched off
by the electronic control unit (the PASSENGER
AIR BAG OFF light > page 265 and how they
work comes on and stays on).

ZA\ WARNING
Sitting in the wrong position can increase the
risk of serious injury in crashes.
—To reduce the risk of injury when the airbags
inflate, the driver and passengers must al-
ways sit in an upright position, must not
lean against or place any part of their body
too close to the area where the airbags are
located.
— Occupants who are unbelted, out of position
or too close to the airbag can be seriously in-
jured by an airbag as it unfolds with great
force in the blink of an eye > page 254.

ZA\ WARNING
A child in a rearward-facing child seat instal-
led on the front passenger seat will be seri-
ously injured and can be killed if the front air-
bag inflates - even with an Advanced Airbag
System.
— The inflating airbag will hit the child seat or
infant carrier with great force and will

— will go out if the front passenger seat is occu-
pied by an adult as registered by the capacitive
passenger detection system.
— The PASSENGER AIR BAG OFF light must come
on and stay on if the ignition is on and...
—a car bed has been installed on the front pas-
senger seat, or
—arearward-facing child restraint has been in-
stalled on the front passenger seat, or
—a forward-facing child restraint has been instal-
led on the front passenger seat,
—and if the electrical capacitance registered on
the front passenger seat is equal to or less than
the combined capacitance of a typical 1 year-
old infant and one of the rearward-facing or
forward-facing child restraints listed in Federal
Motor Vehicle Safety Standard 208 with which
the Advanced Airbag System in your vehicle was
certified.
If the front passenger seat is not occupied, the
front airbag will not deploy, and the PASSENGER
AIR BAG OFF light will stay on. Never installa
rearward-facing child restraint on the front pas-
senger seat, the safest place for a child in any
kind of child restraint is at one of the seating po-

If the PASSENGER AIR BAG OFF light comes on
when one of the conditions listed above is met,
be sure to check the light regularly to make cer-
tain that the PASSENGER AIR BAG OFF light
stays on continuously whenever the ignition is
on. If the PASSENGER AIR BAG OFF light does
not appear on and does not stay on all the time,
stop as soon as it is safe to do so and
— reactivate the system by turning the ignition off
for more than 4 seconds and then turning it on
again;
— remove and reinstall the child restraint. Make
sure that the child restraint is properly installed
and that the safety belt for the front passenger
seat has been correctly routed through the
child restraint as described in the child restraint
manufacturer's instructions;
— make sure that the convertible locking retractor
on the safety belt for the front passenger seat
has been activated and that the safety belt has
been pulled tight.
— make sure that no electrical device (such as a
laptop, CD player, electronic games device,
power inverter or seat heater for child seats) is
placed or used on the front passenger seat if
the device is connected to the 12-volt socket or
the cigarette lighter socket;
— make sure that no seat heater has been retrofit-
ted or otherwise added to the front passenger
seat;
— make sure that nothing can interfere with the
safety belt buckles and that they are not ob-
structed;
— make sure that there are no wet objects (such
as a wet towel) and no water or other liquids on
the front passenger seat cushion.

— take the child restraint off the front passenger
seat and install it properly at one of the rear
seat positions. Have the airbag system inspect-
ed by your Audi dealer immediately.
— move the child to a rear seat position and make
sure that the child is properly restrained ina
child restraint that is appropriate for its size
and age.
The PASSENGER AIR BAG light should NOT
come on...
The PASSENGER AIR BAG OFF light should NOT
come on when the ignition is on and an adult is
sitting in a proper seating position on the front
passenger seat. If the PASSENGER AIR BAG OFF
light comes on and stays on or flashes for about
5 seconds while driving, under these circumstan-
ces, make sure that:
— the adult on the front passenger seat is proper-
ly seated on the center of the seat cushion with
his or her back up against the backrest and the
backrest is not reclined,
— the adult is not taking weight off the seat by
holding on to the passenger assist handle
above the front passenger door or supporting
their weight on the armrest,
— the safety belt is being properly worn and that
there is not a lot of slack in the safety belt web-
bing,
— there are no aftermarket seat covers or cush-
ions or other things (such as blankets) on the
front passenger seat that might cause the ca-
pacitive passenger detection system to miscal-
culate electrical capacitance.

monitoring the Advanced Airbag System

— If the PASSENGER AIR BAG OFF light does
not go off when an adult who is not very
small is sitting on the front passenger seat
after taking the steps described above,
make sure the adult is properly seated and
restrained at one of the rear seating posi-
tions. Have the airbag system inspected by
your authorized Audi dealer before trans-
porting anyone on the front passenger seat.

ZA WARNING
An airbag system that is not functioning prop-
erly cannot provide supplemental protection
in a frontal crash.
—If the airbag indicator light > page 238
comes when the vehicle is being used, have
the system inspected immediately by your
authorized Audi dealer. It is possible that
the airbag will inflate when it is not sup-
posed to, or will not inflate when it should.


Z\ WARNING
— If the status of the Advanced Airbag System
has changed while the vehicle is moving, the
PASSENGER AIR BAG OFF light blinks for
about 5 seconds to catch the driver's atten-
tion. If this happens, always stop as soon as
it is safe to do so and check the steps descri-


bed above.


Z\ WARNING
If the front airbag inflates, a child without a
child restraint, or in a rearward-facing child
safety seat, or in a forward-facing child re-
straint that has not been properly installed
will be seriously injured and can be killed.
— Even though your vehicle is equipped with
an Advanced Airbag System, make certain
that all children, especially 12 years and
younger, always ride on the back seat prop-
erly restrained for their age and size.
— Always install forward or rear-facing child
seats on the rear seat — even with an Ad-
vanced Airbag System.
— If you must install a rearward-facing child
seat on the front passenger seat because of
exceptional circumstances and the PASSEN-
GER AIR BAG OFF light does not appear and
stay on, immediately install the rear-facing
child seat in a rear seating position and have
the airbag system inspected by your Audi
dealer.
— If, in exceptional circumstances, you must
install a forward-facing child restraint on
the front passenger seat, always move the
seat into its rearmost position in the seat's

When the system is triggered, the airbag is filled
with propellant gas and breaks through a seam in
the seat surface area marked “AIRBAG”. It ex-
pands between the side trim panel and the pas-
senger. In order to help provide this additional
protection, the side airbag must inflate within a
fraction of a second at very high speed and with
great force. The supplemental side airbag could
injure you if your seating position is not proper or
upright or if items are located in the area where
the supplemental side airbag expands. This ap-
plies especially to children > page 278, Child

Airbags are only supplemental restraints. Always
properly wear safety belts and ride in a proper

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 provide supplemental
protection.

ZA WARNING
An inflating side airbag can cause serious or
fatal injury. Improperly wearing safety belts
and improper seating positions increase 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 supple-
mental 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 replacement
upholstery over the front seatbacks that
have not been specifically approved by
Audi.
— Never use additional seat cushions that
cover the areas where the side airbags de-

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

Important safety instructions on the side
curtain airbag system
Applies to: vehicles with side curtain airbags
Airbags are only supplemental restraints. Always
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 help the safety belts and airbags
do their job to provide supplemental protection.

ZA WARNING
Improperly wearing safety belts and improper
seating positions increase the risk of serious
personal injury and death whenever a vehicle
is being used.
— Never let occupants place any parts of their
bodies in the area from which the side cur-
tain airbag inflate.
— Always make sure that the side curtain air-
bags can inflate without interference.
— 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 airbag deployment and can
cause personal injury in a collision.
— Never use hangers to hang clothes on the
hooks.
— Only use factory-installed sun shades or, if
shades installed after the vehicle leaves the
factory, use only genuine Audi sun shades.
— Never swing the sun visors over to the side
windows if things such as pens, garage door
openers, hands-free speakers, etc. are at-
tached to the sun visors. They could come
loose and cause serious injury if the side cur-
tain airbag inflates.
— A deploying airbag inflates in a fraction of a
second and with great force.
— Never attach objects to the cover or in the
deployment zone of a side curtain airbag.
— The airbag deployment zones must be kept
clear at all times. Make sure there are no ob-
jects, pets, or other persons in the space be-
tween any vehicle occupant and any airbag
at any time.
— Do not attach any accessories to the doors.

Child safety
Important information
Introduction
The rear seat is generally the safest place ina
collision.
The physical principles of what happens when
your vehicle is in a crash apply also to children
= page 246, 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
greater risk of serious injury in crashes than
adults.
Because children's bodies are not fully developed,
they require restraint systems especially de-
signed for their size, weight, and body structure.
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.
Ina 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 restraints, like
adult safety belts, must be used properly to be
effective. Used improperly, they can increase the
risk of serious injury in an accident.
All children, especially those 12 years and young-
er must always ride in the back seat properly re-
strained for their age and size. If you must install
a child restraint on the front passenger seat in
exceptional circumstances, be sure to read and
heed the important information and warnings
= page 254. Infants and other children who are
properly restrained in an appropriate child re-
straint that is for their size and age can benefit
from the protection that supplemental side air-
bags provide in some kinds of crashes.

vided by the:

— National Highway Traffic Safety Administration
(NHTSA), currently at : http://www.safercar.gov
(for the USA)
— Transport Canada Information Centre, currently
at: http://www.tc.gc.ca (for Canada)
Consult the child safety seat manufacturer's in-
structions in order to be sure the seat is right for
your child's size > page 282, 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, Ad-
vanced Airbags, and the installation of child re-
straints 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 information, we cannot re-
peat it all here. We urge you to read the detailed
information 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.

ZA WARNING
— Accident statistics have shown that children
are generally safer in the rear seat area than
in the front seating position. Always restrain
any child age 12 and under in the rear.
— All vehicle occupants and especially children
must be restrained properly whenever riding
in a vehicle. An unrestrained 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 also at greater risk of injury or death
through contact with an inflating airbag.
— A suitable child restraint properly installed
and used at one of the rear seating positions
provides the highest degree of protection
for infants and small children in most acci-
dent situations.
