Important safety instructions on
monitoring the Advanced Airbag System
ZA WARNING
— If the status of the Advanced Airbag System
has changed while the vehicle is moving, the
PASSENGER AIR BAG OFF #¥; ON ® light
blinks for about 5 seconds to catch the driv-
er's attention. If this happens, always stop
as soon as it is safe to do so and check the
steps described above.
— 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,
have the airbag system inspected by your
authorized Audi dealer before transporting
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 18
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.

ZA\ 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.
— 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, have the airbag system inspect-
ed 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
fore and aft adjustment range, as far away

8S8012721BA
Airbag system


from the airbag as possible. The backrest
must be adjusted to an upright position.
Make sure that the PASSENGER AIR BAG
OFF %; light comes on and stays on all the
time whenever the ignition is switched on.


ZA WARNING
If the PASSENGER AIR BAG OFF %; light does
not go out when an adult is sitting on the
front passenger seat after taking the steps
described above, have the airbag system in-
spected by your Audi dealer before transport-
ing anyone on the front passenger seat.

@ Tips
If the capacitive passenger detection system
determines that the front passenger seat is
empty, the frontal airbag on the passenger
side will be turned off, and the PASSENGER
AIR BAG OFF 3; light will stay on.
Repair, care and disposal of the airbags
Parts of the airbag system are installed at many
different places on your Audi. Installing, remov-
ing, servicing or repairing a part in an area of the
vehicle can damage a part of an airbag system
and prevent that system from working properly
in a collision.
There are some important things you have to
know to make sure that the effectiveness of the
system will not be impaired and that discarded
components do not cause injury or pollute the
environment.

ZA WARNING
Improper care, servicing and repair proce-
dures can increase the risk of personal injury
and death by preventing an airbag from de-
ploying when needed or deploying an airbag
unexpectedly:
— Never cover, obstruct, or change the steer-
ing wheel horn pad or airbag cover or the in-
strument panel or modify them in any way.
— Never attach any objects such as cup holders
or telephone mountings to the surfaces cov-
ering the airbag units.


— For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one mois-
tened with plain water. Solvents or cleaners
could damage the airbag cover or change
the stiffness or strength of the material so
that the airbag cannot deploy and protect
properly.
— Never repair, adjust, or change any parts of
the airbag system.
— All work on the steering wheel, instrument
panel, front seats or electrical system (in-
cluding the installation of audio equipment,
cellular telephones and CB radios, etc.)
must be performed by a qualified technician
who has the training and special equipment
necessary.
— For any work on the airbag system, we
strongly recommend that you see your au-
thorized Audi dealer or qualified workshop.
— Never modify the front bumper or parts of
the vehicle body.
— 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 Au-
di.
— Never use additional seat cushions that
cover the areas where the side airbags in-
flate.
— Damage to the original seat covers or to
the seam in the area of the side airbag
module must always be repaired immedi-
ately by an authorized Audi dealer.
— The airbag system can deploy only once. Af-
ter an airbag has been deployed, it must be
replaced with new replacement parts de-
signed and approved especially for your Audi
model version. Replacement of complete
airbag systems or airbag components must
be performed by qualified workshops only.
Make sure that any airbag service action is
entered in your Audi Warranty & Mainte-
nance booklet under AIRBAG REPLACEMENT
RECORD.
— For safety reasons in severe accidents, the
alternator and starter are separated from

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 collision.
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 designed to re-
duce the likelihood of serious injuries, other inju-
ries, for example, swelling, bruising and minor
abrasions 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 warning light in the instrument clus-
ter
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 malfunction (warning/
indicator light is on) > page 18.


Z\ WARNING
— Safety belts and the airbag system can only
provide protection when occupants are in
the proper seating position > page 198.
— If the airbag indicator light > page 18
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.

The risk of injury to the leg area can be reduced

Fig. 160 Inflated airbags protecting in a frontal collision

The knee airbag system has been designed so
that the airbags for the driver and front passen-
ger deploy in certain but not all frontal collisions.
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 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 > page 198, fig. 157.
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 this takes place 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 belts slow down and limit the oc-
cupant's forward movement and help to reduce
the risk of injury.

8S58012721BA
Airbag system

— the two side airbags located in the sides of the
front backrests
— the airbag warning light in the instrument clus-
ter.
The airbag system is monitored electronically to
make certain that it is functioning properly at all
times. Each time you turn on the ignition, the air-
bag system indicator light will come on for a few
seconds (self diagnostics).
The side airbag system supplements the safety
belts and can help to reduce the risk of injury to
the driver's and front passenger's upper torso on
the side of the vehicle that is struck in a side col-
lision. The airbag deploys in side impacts and on-
ly when the vehicle acceleration registered by the
control unit is high enough. If this rate is below
the reference value programmed into the control
unit, the side airbags will not be triggered, even
though the car may be badly damaged as a result
of the collision. It is not possible to define an air-
bag triggering range that will cover every possi-
ble angle of impact, since the circumstances will
vary considerably between one collision and an-
other. Important factors include, for example,
the nature (hard or soft) of the impacting object,
the angle of impact, vehicle speed, etc.
= page 208, Important safety instructions on
the side airbag system.
Aside from their normal safety function, safety
belts work to help keep the driver or front pas-
senger 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 occu-
pant restraint system in your vehicle. Always re-
member 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 rea-
son why you should always wear your safety
belts, not just because the law requires you to do
so > page 182, General notes.
It is important to remember that while the sup-
plemental side airbag system is designed to re-
duce the likelihood of serious injuries, other inju-
ries, for example, swelling, bruising, friction
burns and minor abrasions can also be associated
with deployed side airbags. Remember too, side
airbags will deploy only once and only in certain
kinds of accidents - your safety belts are always
there to offer protection.
Vehicle damage, repair costs or even the lack of
vehicle damage are not necessarily an indication
of over-sensitive or failed airbag activation. In
some collisions, both front and side airbags may
inflate. Remember too, that airbags will deploy
only once and only in certain kinds of collisions -
your safety belts are always there to offer protec-
tion in those accidents in which airbags are not
supposed to deploy or when they have already
deployed.
The
side airbag system will not deploy:
— when the ignition is switched off
— in side collisions when the acceleration meas-
ured by the sensor is too low
—in front-end collisions
—in rear-end collisions
—in rollovers.
In some types of accidents the front airbags and
side airbags may be triggered together.

Z\ WARNING
— Safety belts and the airbag system will only
provide protection when occupants are in
the proper seating position > page 208.
— If the airbag indicator light > page 18
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.

Child safety


— Never install a rearward facing child safety
seat on the front passenger seat if the PAS-
SENGER AIR BAG OFF 3%; light does not
turn on and stay on. Have the system in-
spected immediately by an authorized Audi
dealer or authorized Audi Service Facility.


ZA\ WARNING
— Forward-facing child seats installed on the
front passenger seat may interfere with the
deployment of the airbag and cause serious
personal injury to the child.
— 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 the following special pre-
cautions to be taken:
— Always make sure that the forward-facing
seat has been designed and certified by its
manufacturer for use on a front passenger
seat with a front and side airbag.
— Always carefully follow the manufacturer's
instructions provided with the child seat or
infant carrier.
— Never put the forward-facing child re-
straint up against or very near the instru-
ment panel.
— Always move the front passenger seat to
the highest position in the up and down
adjustment range and move it back to the
rearmost position in the seat's fore and aft
adjustment range, as far away from the
airbag as possible, before installing the
forward-facing child restraint.
— Always make sure that the safety belt up-
per anchorage is behind the child restraint
and not next to or in front of the child re-
straint so that the safety belt will be prop-
erly positioned.
— Always make sure that nothing prevents
the front passenger's seat from being
moved to the rearmost position in its fore
and aft adjustment range.
— Never place objects on the seat (such as a
laptop, CD player, electronic games device,
power inverter or seat heater for child
seats). These may influence the electrical

capacitance measured by the capacitive
passenger detection system and can also
fly around in an accident and cause serious
personal injury.
— Never place or use any electrical device
(such as a laptop, CD player, electronic
games device, power inverter or seat heat-
er for child seats) on the front passenger
seat if the device is connected to the 12-
volt socket or the cigarette lighter socket.
— Ifa seat heater has been retrofitted or
otherwise added to the front passenger
seat, never install any child restraint sys-
tem on this seat.
— Make sure that there are no wet objects
(such as a wet towel) and no water or oth-
er liquids on the front passenger seat
cushion.
— Always make sure that the PASSENGER
AIR BAG OFF #; light comes on and stays
on all the time whenever the ignition is
switched on.
— Never install a forward-facing child safety
seat on the front passenger seat if the
PASSENGER AIR BAG OFF %; light does
not turn on and stay on. Have the system
inspected immediately by an authorized
Audi dealer or authorized Audi Service Fa-
cility.
— Always buckle the child seat firmly in place
even if a child is not sitting in it. A loose
child seat can fly around during a sudden
stop or in a collision.
— Always read and heed all WARNINGS
whenever using a child restraint in a vehi-
cle > page 182, Safety belts, > page 189,
Airbag system and > page 210, Important
information.


G) Tips
Always replace child restraints that were in-
stalled in a vehicle during a crash. Damage to
a child restraint that is not visible could cause
it to fail in another collision situation.

Child safety

PNW ete miele laste Relea meal Cele)
Your vehicle is equipped with a front “Advanced
Airbag System” in compliance with United States
Federal Motor Vehicle Safety Standard (FMVSS)
208, as well as Canada Motor Vehicle Safety
Standard (CMVSS) 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” 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
“suppression” requirements 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.
Even though your vehicle is equipped with an Ad-
vanced Airbag system, a child should always ride
in the seat properly restrained for its age and
size. The airbag on the passenger 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 forward-facing child safety seat. It
can be a very dangerous place for an infant or a
larger child in a rearward-facing seat.
The vehicle's Advanced Airbag System has a ca-
Pacitive passenger detection system in the front
passenger seat cushion that can detect the pres-
ence of a baby or a child ina child restraint sys-
tem on this seat.
The capacitive 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 passenger 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 re-
straint system resting on the seat. The measured
capacitance of a child restraint system varies de-
212
pending on the type of system and specific make
and model.
The electrical capacitance of the various types,
makes, and models of child restraints specified
by the U.S. National Highway Traffic Safety Ad-
ministration (NHTSA) in the relevant safety
standard are stored in the Advanced Airbag Sys-
tem control unit together with the capacitances
typical of infants and a 1-year old child. When a
child restraint is used on the front passenger seat
with a typical 1 year-old infant, the Advanced Air-
bag System compares the capacitance measured
by the capacitive passenger detection system
with the data stored in the electronic control
unit.
Ce CM eee ANC Micra lia elle)
system
Regardless of the child restraint that you use,
make sure that it has been certified to meet Safe-
ty Standards and has been certified by its manu-
facturer for use with an airbag. If in exceptional
circumstances you must use it on the front pas-
senger seat, carefully read all of the information
on child safety and Advanced Airbags and heed
all of the applicable WARNINGS. Make certain
that the child and child restraint are correctly rec-
ognized by the capacitive passenger detection
system in the front passenger seat, that the front
passenger airbag is turned off, and that the air-
bag status is always correctly signaled by the
PASSENGER AIR BAG OFF #; light.
Many types and models of child restraints 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 restraints are not 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
child restraint that sits on the seat, when they
are installed on a vehicle seat. These differences
make it virtually impossible to certify compliance
with the requirements for advanced airbags with
each and every child restraint that has ever been
sold in the past or will be sold over the course of
the useful life of your vehicle.

Child safety

For this reason, the United States National High-
way Traffic Safety Administration has published a
list of specific type, makes and models of child
restraints that must be used to certify compli-
ance of the Advanced Airbag System in your vehi-
cle with the suppression requirements of Federal
Motor Vehicle Safety Standard 208. These child

Correct use of child safety seats substantially re-
duces the risk of injury in an accident!
As the driver, you are responsible for the safety of
everybody in the vehicle, especially children:
> Always use the right child safety seat for each
child and always use it properly > page 215.
> Always carefully follow the child safety seat
manufacturer's instructions on how to route
the safety belt properly through the child safe-
ty seat.
> When using the vehicle safety belt to install a
child safety seat, you must first activate the
convertible locking retractor on the safety belt
to prevent the child safety seat from moving
=> page 219.
213

Child safety

> Push the child safety seat down with your full
weight to get the safety belt really tight so that
the seat cannot move forward and sideways
more than 1 in (2.5 cm).
Always remember: Even though your vehicle is
equipped with an Advanced Airbag system, a
child should always ride in the seat properly re-
strained for its age and size.


Z\ WARNING
Not using a child safety seat, using the wrong
child safety seat or improperly installing a
child restraint increases the risk of serious
personal injury and death.
— 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.
— 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 cush-
ion. The child restraint must not tip or
lean to either side. Audi does not recom-
mend using child safety seats that rest on
legs or tube-like frames. They do not pro-
vide 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 in-
structions provided by the manufacturer
of the seat you are using.
— Never let more than one child occupy a child
safety seat.
— Never let babies or older children ride ina
vehicle while sitting on the lap of another
passenger.

214

— Holding a child in your arms is never a sub-
stitute for a child restraint system.
— The strongest person could not hold the
child with the forces that exist in an acci-
dent. The child will strike the interior 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 passenger seat.
A child will be seriously injured and can be
killed when the passenger airbag inflates -
even with an Advanced 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.
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 manu-
facturer for use on a front seat with a pas-
senger front and side airbag.
— Always carefully follow the manufacturer's
instructions provided with the child safety
seat or carrier.
— Always move the front passenger seat into
the rearmost position of the passenger
seat's fore and aft adjustment range, and
as far away from the airbag as possible be-
fore installing the child restraint.
— Always make sure that nothing prevents
the front passenger's seat from being
moved to the rearmost position in its fore
and aft adjustment range.
— Always make sure that the backrest is in
the upright position.
— Never place or use any electrical device
(such as a laptop, CD player, electronic
games device, power inverter or seat heat-
er for child seats) on the front passenger
seat if the device is connected to the 12-
volt socket or the cigarette lighter socket.
