protection .
• Airbag work most effectively when used with properly worn
safety belts.
• Therefore , always wear your safety belts and make sure that
everybody in your vehicle is properly restrained .
& WARNING
A person on the front passenger seat, especially infants and small
children , will receive serious injuries and can even be killed by
being too close to the airbag when it inflates.
• Although the Advanced Airbag System in your vehicle is
designed to turn off the front passenger airbag if an infant or a
small child is on the front passenger seat , nobody can absolutely
guarantee that deployment under these special conditions is
impossible in all conceivable situations that may happen during
the useful life of your vehicle .

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 .
Controls and equip­
ment Safety first Vehicle operation
•
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.
• An airbag monitoring syste m and indica tor l ight in the instru ­
ment cluster=>
page 157.
• The PASSENGER AIR BAG OFF light comes on and stays on in the
center of the instrument panel=>
page 157, fig. 133 and tells you
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
seat passenger that senses whether that safety be lt is latched or not
and t ransmits this information to the electronic control unit.
& WARNING
Damage to the front pa ssenger seat can prevent the front airbag

More important things to know about front
airbags
Fig . 132 Inflate d front
airbags
Safety belts are important to help keep front seat occupants in the
proper seated posit ion so that airbags can unfold properly and
provide supp lemental protection in a frontal collision.
The front airbags are designed to provide additional 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 occupant is properly
seated as far as possible from the air bag,
• and the head restraints have been properly adjusted .
Safety first
Airbag system
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 projectiles, and be pushed into you if the airbag inflates .
When an airbag deploys, fine dust is released . This is norma l 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 supplemental airbag
system is designed to reduce the likel ihood of serious injuries, other
injuries, for example swelling, bruising and minor abrasions , can
also happen when airbags inflate. Airbags do not protect the arms
or the lower parts of the body. Front airbags only supplement the
three point safety be lts in some frontal collisions in which the
vehic le deceleration is high enough to dep loy the a irbags.
Front airbags will not deploy:
• if the ignition is switched off when a crash occurs,
• in side collisions,
• in rear -end collisions,
• in rollovers,
• when the crash deceleration measured by the airbag system is
less than the minimum threshold needed for airbag deployment as
registered by the electronic control unit.
The front passenger airbag will also not deploy:
• when the front passenger seat is not occupied,
• when the weight on the front passenger seat as sensed by the
Advanced Airbag System indicates that the front airbag on the
passenger side has to be turned off by the electronic control unit
(the
PASSENGER AIR BAG OFF light comes on and stays onl.

Sitting in the wrong position can increase the risk of serious injury

& WARNING (continued)
• To reduce the risk of injury when the airbags inflate, the driver
and passengers must always 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 injured by an airbag as it unfolds with
great force in the blink of an eye~ page
147.
& 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, center arm rest, 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 .
& WARNING
Objects between you and the airbag will increase the risk of injury
in a crash by interfering with the way the airbag unfolds or by
being pushed into you as the airbag inflates .
• Never hold things in your hands or on your lap when the vehicle
is in use .
• Never transport items on or in the area of the front passenger
seat . Objects could move into the area of the front airbags during
& WARNING (continued)
braking or other sudden maneuver and become dangerous projec­
tiles that can cause serious personal injury if the airbags inflate.
• Never place or attach accessories or other objects (such as cup
holders, telephone brackets, large , heavy or bulky objects) on the
doors , over or near the area marked "AIRBAG" on the steering
wheel, instrument panel , seat backrests or between those areas
and yourself . These objects could cause injury in a crash, espe­
cially when the airbags inflate .
• Never recline the front passenger's seat to transport objects .
Items can also move into the area of the side airbag or the front
airbag during braking or in a sudden maneuver . Objects near the
airbags can become projectiles and cause injury, particularly when
the seat is reclined.
& WARNING
The fine dust created when airbags deploy can cause breathing
problems for people with a history of asthma or other breathing
conditions.
• To reduce the risk of breathing problems , those with asthma or
other respiratory conditions should get fresh air right away by
getting out of the vehicle or opening windows or doors .
• If you are in a collision in which airbags deploy, wash your
hands and face with mild soap and water before eating .
• Be careful not to get the dust into your eyes, or into any cuts or
scratches .
• If the residue should get into your eyes , flush them with
water. •

the Advanced Airbag System
& WARNING
An airbag system that is not functioning prope rly cannot prov ide
supplemental protection in a frontal crash.
• If the airbag ind icator light comes on , it means that there may
be something wrong with the Advanced Airbag System . It is
possible that the airbag will inflate when it is not supposed to , or
will not inflate when it should.
• Have the airbag system inspected immediately by your Audi
dealer.
& WARNING
If the front airbag inflates , a child without a child restraint, in a
rearward-facing child safety se at or in a forward-facing child
restraint 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 ch ildren , especially 12 years and
younger, always ride on the back seat properly restrained for their age and size .
Controls and equip­ ment Safety first
Vehicle operation
& WARNING (continued )
• If you must in stall a rearward-facing child safety seat on the
front passenger seat because of exceptional circumstances and
the PASSENGER AIR BAG OFF light does not appear and stay on ,
immediately install the rear -facing child safety seat in a rear
seating posit ion and have the airbag system inspected by your
Audi dealer .
• A tight tether or other strap on a rearward-fa cing child restraint
attached to the front passenger seat can put too much pressure
on the weight-sensing mat in the seat and reg ister more weight
than is actually on the seat. The heavier weight registered can make the system work as though an adult were on the seat and
deploy the Advanced Airbag when it must be suppressed causing
serious or even fatal injury to the child .
• If, in exceptional circumstances, you must in stall a forward ­
fac ing child restra int on the front passenger seat , always move the
seat into its rearmost position in the seat's fore and aft adjust ­
ment range , as far away 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 .
& 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 inspected by your Audi
dealer before transporting anyone on the front passenger seat .
