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 child in a rearward-facing seat.
The Advanced Airbag System in your vehicle has been certified to comply with the Requirements of United States Federal Motor
Vehicle Safety Standard 208 as applicable at the time your vehicle
was manufactured.
The Standard requires the front airbag on the passenger side to be
turned off ("suppressed") if a child up to about one year of age restrained in one of the rear -facing or forward -facing infant
restraints listed in Federal Motor Vehicle Safety Standard 208 with
which the Advanced Airbag System in your vehicle was certified has
been installed on the front passenger seat. For a listing of the child
restraints that were used to certify compliance with the US Safety
Standard =>
page 170.
The PASSENGER AIR BAG OFF light in the instrument panel tells you
when the front Advanced Airbag on the passenger side has been
turned off by the electronic control unit.
Each time you turn on the ignition, the
PASSENGER AIR BAG OFF
light will come on for a few seconds and:
• will stay on if the front passenger seat is not occupied,
• will stay on if there is a small child or child restraint on the front
passenger seat,
• will go off if the front passenger seat is occupied by an adult as
registered by the weight -sensing mat=>
page 157, "Monitoring the
Advanced Airbag System".
The
PASSENGER AIR BAG OFF light comes on when the control unit
detects a total weight on the front passenger seat that requires the
front airbag to be turned off.
If the total weight on the front passenger seat is more than that of
a typical 1 year-old child but less than the weight of a small adult,
the front airbag on the passenger side can deploy (the
PASSENGER
AIR BAG OFF
light does not come onl. If the PASSENGER AIR BAG OFF
light does not come on, the front airbag on the passenger side
has not been turned off by the electronic control unit and can
deploy if the control unit senses an impact that meets the condi­
tions stored in its memory.
For example, the airbag may deploy if:
• a small child that is heavier than a typical 1 year-old child is on
the front passenger seat (regardless of whether the child is in one
of the child safety seats listed =>
page 170), or
• a child who has outgrown child restraints is on the front
passenger seat .
If the front passenger airbag is turned off, the
PASSENGER AIR BAG
OFF
light comes on in the instrument cluster and stays on .
The front airbag on the passenger side may
not deploy (the
PASSENGER AIR BAG OFF light does not illuminate and stay litl even
if a small adult or teenager, or a passenger who is not sitting upright
with their back against a non-reclined backrest with their feet on the
vehicle floor in front of the seat is on the front passenger seat
=> page 130, "Proper seating position for the driver".
If the front passenger airbag deploys , the Federal Standard requires
the airbag to meet the "low risk" deployment criteria to reduce the
risk of injury through interaction with the airbag. "Low risk" deploy­
ment occurs in those crashes that take place at lower decelerations
as defined in the electronic control unit=>
page 157, "PASSENGER
AIR BAG OFF light".
Always remember, a child safety seat or infant carrier installed on
the front seat may be struck and knocked out of position by the rapidly inflating passenger's airbag in a frontal collision. The airbag
could greatly reduce the effectiveness of the child restraint and
even seriously injure the child during inflation.
For this reason, and because the back seat is the safest place for
children -when properly restrained according to their age and size
- we strongly recommend that children always sit in the back seat
=>
page 168, "Child Safety" . .,

& WARNING
A child in a rearward-facing child safety seat installed on the front
passenger seat will be seriously injured and can be killed if the
front 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, door or roof. • If you must install a rearward facing child safety seat on the
front passenger seat because of 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 airbag system inspected by your
Audi dealer .
• Forward-facing child safety seats installed on the front
passenger's seat may interfere with the deployment of the airbag
and cause serious personal injury to the child.
& 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 .
• Never put the forward -facing child restraint up against or very
near the instrument panel.
• 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 forward -facing child
restraint. 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 .
Controls and equip­ ment Safety first
Vehicle operation
& WARNING
To reduce the risk of serious injury , make sure that the PASSENGER
AIR BAG OFF light will be displayed whenever a child restraint is installed on the front passenger seat and the ignition is switched
on .
• If the PASSENGER AIR BAG OFF light does not stay on , perform
the checks described=>
page 157, "Monitoring the Advanced
Airbag System ".
• Take the child restraint off the front passenger seat and install
it properly at one of the rear seat positions if the PASSENGER AIR
BAG OFF light does not stay on.
• Have the airbag system inspected by your Audi dealer immedi­
ately. • Always carefully follow instructions from child restraint manu­
facturers when installing child restraints .
& WARNING
If, in exceptional circumstances, you must install a forward or
rearward-facing child restraint on the front passenger's seat :
• Improper installation of child restraints can reduce their effec­
tiveness or even prevent them from providing any protection.
• An improperly installed child restraint can interfere with the
airbag as it deploys and seriously injure or even kill the child -
even with an Advanced Airbag System .
• Always carefully follow the manufacturer's instructions
provided with the child safety seat or carrier .
• Never place additional items on the seat that can increase the
total weight registered by the weight -sensing mat and can cause
injury in a crash . •

Advanced front airbag system
Your vehicle is equipped with a front Advanced Airbag System in
compliance with United States Federal Motor Vehicle Safety Stan­
dard 208 as applicab le at the time your vehicle was manufactured.
Th e front Advanced Airbag System supplements the safety belts to
provide additional protection for the driver's and front passenger 's
heads and upper bodies in frontal crashes. The airbags inflate only
in frontal impacts when the vehicle deceleration is high enough .
The front Advanced Airbag System for the front seat occupants is not a substitute for your safety be lts. Rather, it is part of the overa ll
occupant restraint system in your vehicle. A lways remember that
the airbag syste m can only help to protect you, if you a re sitting
upright, wearing your safety be lt and wearing it proper ly. This is why
you and your passengers must a lways be proper ly restrained, not
just because the law requires you to be .
The Advanced Airbag System in your vehicle has been certified to meet the " low risk" requirements for 3 and 6 year-old children on the
passenger side and very small adults on the driver side . The low risk
deployment cr iteria are intended to help reduce the risk of injury
through interaction with the front airbag that can occur, for
examp le, by being too c lose to the steering wheel and instrument
panel when the airbag inflates .
Controls and equip­
ment Safety first Vehicle operation
I
n addition, the system has been certified to comply with the
"suppression" requirements of the Safe ty Standard, to turn off the
front airbag for infants 12 months old and younger who are restrained on the front passenger seat in child restraints that are
listed in the Standard=>
page 170, "Child restraints and Advanced
Airbags" .
"Suppression" requires the front airbag on the passenger side to be
turned off if:
• a child up to about one year of age is restrained on the front
passenger seat in one of the rear-facing or forward-facing infant
res traints listed in Federal Motor Vehicle Safety Standard 208 with
wh ich the Advanced Airbag System in your vehicle was certified. For
a listing of the child rest raints that were used to certify your
vehic le's compliance with the US Safety Standard=>
page 170,
• weight less than a threshold leve l stored in the cont rol unit is
detected on the front passenger seat.
When a person is detected on the front passenger seat, weighing more than the total weight of a child that is about 1 year old
restrained in one of the rear-facing or forward -facing infant
restraints (lis ted in Federal Motor Vehicle Safety Standard 208 with
which the Advanced Airbag System in your vehicle was certified),
the front airbag on the passenger side may or may not deploy .
The
PA SS EN GER AIR BA G OFF light comes on when the e lectronic
control unit detects a total weight on the front passenger seat that
requires the front airbag to be turned off. If the

Advanced Airbag System components
The front passenger seat in your vehicle has a lot of very important
parts of the Advanced Airbag System in it. These parts inc lude the
weight -sensing mat, sensors, wiring, brackets, and more. The func ­
tion of the system in the front passenger seat is checked by the e lec ­
tronic contro l unit when the igni tion is on. The control unit monitors
the Advanced Airbag System and turns the airbag indicator light on
when a malfunction in the system components is detected . The
function of the airbag indicator light is described in greater detail
below. Because the front passenger seat contains important parts
of the Advanced Airbag System, you must take care to prevent it
from being damaged. Damage to the seat may prevent the
Advanced Airbag for the front passenger seat from doing its job in a crash.
T he front A dvance d Airb ag Syst em con sis ts of th e
following:
• Crash sensors in the front of the vehicle that measure vehicle
acceleration/dece leration to prov ide information to the Advanced
Airbag System about the severity of the crash .
• An electronic control unit, with integrated crash sensors for front
and side impacts. The control unit "decides" whether to fire the
front airbags based on the information received from the crash sensors. The contro l unit a lso "decides" whether the safety belt
pretensioners should be activated .
• A dual -stage Advanced Airbag with gas generator for the driver
inside the steering wheel hub .
• A dual -stage Advanced Airbag and gas generator inside the
instrument pane l for the front passenger .

•
A weight -sensing mat under the upholstery padding of the front
passenger sea t cushion that measures the total weight on the seat .
The information registered is sent continuously to the e lectronic
control unit to regula te dep loyment of the front Advanced Airbag on
the passenger side.

when the front Advanced Airbag on the passenger side has been
turned off .
• A sensor be low the safety belt latch for the front seat passenger
to measure the tension on the safety belt . The tension on the safety
belt and the weight registered by the weight -se nsing mat help the
control unit "decide" whether the front airbag for the front
passenger sea t should be turned off o r not =>
page 147, "Child
restraints on the front seat -some important things to know" .
• A sensor in the safety belt latch for the dr iver and for the front
