& 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 armrest, door or roof .
• Always install rear-facing child safety seats on the rear seat.
• 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
authorized 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

Advanced Airbag System components
Th e front passenger seat in your veh icle has a lot of very important
parts of t he A dvanced A irbag System in it. These parts incl ude t he
we ight-sens ing mat, sensors, wiring, brackets, and more. The func- tion of the system
in the front passenger seat is checked by the elec­
t ronic c ontro l unit w hen the ignitio n is o n. The contr ol unit mon itors
t he Advanced Airbag System and tu rns the airbag indicato r light o n
w hen a malfunction in t he system components is detected. The func­
t ion of the a irbag indicator light is descr ibed in greater deta il below .
Because the front passenge r seat co nta ins impo rtant parts of t he
Adva nced Ai rbag System, you must ta ke care to p reve nt i t from be ing
damaged. Damage to the seat may p revent the A dvanced A irbag for
t he fro nt passenge r se at from do ing its job in a crash.
The front Advanced Airbag System consists of the
following:
• Cras h sensors in the front of t he vehicle that measu re vehicle
a cc ele ration/de ce le ra tion to provi de i nfo rm ation to the Advanced
Airbag System about the severity of the crash .
• An e lec tron ic contro l unit, w it h i ntegrated crash sensors fo r front
and side impacts. The contro l unit "dec ides" w het her to fire the front
a irbag s based o n the inform ation receive d fro m t he c rash se nso rs.
The contro l unit also "decides" whether the safety be lt pretens ioners
shoul d be activ at ed .
• An Advanced Air bag with gas generator and control va lve for the
dr ive r in side t he steering wheel hub.
• An Advanced Air bag with gas generator and control va lve inside
t he inst rument pa ne l for the fron t passenge r.
• A weight-sensi ng mat unde r th e up ho ls tery pad ding of the front
passenger s eat cushion that measures the tota l we igh t on the seat .
Th e informat io n registered is sent continuous ly to the elect ronic
con trol unit to regulate deployment of t he front Advanced A irbag o n
the passenger side.
• An airbag mon itoring system a nd ind icator light in the ins trument
cl uster => page

driver seat will prevent the Advanced Airbag System from func­
tioning properly.
• Repairs to the front pa ssenger seat must be performed by qual­
ified and properly trained workshop personnel.
• Never remove the front passenger or driver seat from the
vehicle.
• Never remove the upholstery from the front passenger seat .
• Never disassemble or remove parts from the seat or disconnect
wires from it .
• Never carry sharp objects in your pockets or place them on the
seat . If the weight-sensing mat in the passenger seat is punctured
it cannot work properly.
• Never carry th ings on your lap or carry objects on the passenger
seat. Such items can in crease the weight registered by the weight­
sensing mat and send the wrong information to the airbag control
unit.
Controls and equip­ ment Safety first Vehicle operation
& WARNING
(co ntinued )
• Never store item s under the front passenger seat . Parts of the
Advanced Airbag Sy stem under the passenger seat could be
damaged , preventing them and the airb ag system from working
properly .
• Never place seat covers or replacement upholstery that have
not been specifically approved by Audi on the front seats .
• Seat cover s can prevent the Advanced Airbag System from
recognizing child re straints or occupants on the front passenger
seat and prevent the side airbag in the seat backrest from
deploying properly .
• Never u se cushions, pillow s, blankets or similar items on the
front passenger seat. The additional padding will prevent the
weight-sensing mat in the seat from ac curately registering the
child restraint or person on the seat and prevent the Advanced
Ai rbag System from functioning properly .
• If you must use a child restraint on the front passenger seat
and the child restraint manufacturer'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 ch ild restraint is
installed on the front passenger seat.
• If the PASSENGER AIR BAG OFF light does not come on and
stay on, immediately install child restraint in a rear seating posi­
tion and have the airbag system inspected by your authorized Audi dealer. •
