• A sensor in the safety belt latch for the driver and for the front
seat passenger t hat senses wh eth er that safety belt is latched or not
and transm its this information to t he electron ic control unit .
& WARNING
Damage to the front passenger seat can prevent the front airbag
from working properly.
• Improper repair or disassembly of the front passenger and
driver seat will prevent the Advanced Airbag System from func-
tioning properly.
• Repairs to the front passenger 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 things on your lap or carry objects on the
passenger seat . Such items can increase the weight registered by
the weight-sensing mat and send the wrong information to the
airbag control unit .
• Never store items under the front passenger seat . Parts of the
Advanced Airbag System under the passenger seat could be
damaged , preventing them and the airbag system from working
properly.
• Never place seat covers or replacement upholstery that have
not been specifically approved by Audi on the front seats.
• Seat covers can prevent the Advanced Airbag System from
recognizing child restraints or occupants on the front passenger
seat and prevent the side airbag
in the seat backrest from
deploying properly.
& WARNING (continued)
• Never use cushions, pillows, blankets or similar items on the
front passenger seat . The additional padding will prevent the
weight-sensing mat in the seat from accurately registering the
child restraint or person on the seat and prevent the Advanced
Airbag 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 child 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 position
and have the airbag system inspected by your Audi dealer. •
How the Advanced Airbag System
components work together
The front Advanc ed Airba g Syst em and th e side airba gs supplement
t he protection offered by the fro nt three -point safety belts with
pretens ioners and load limiters and t he adjustab le head restraints
to help reduce the risk of injury in a w ide range of accident and
cras h sit uat ion s. Be sure to read the im por ta nt info rm ati on abo ut
safety and heed the WARNINGS in this chapter.
Depl oyment of t he Advanced Airb ag System and th e activa t ion of
the safety belt pretensioners depend on the deceleration measured
by th e crash sensors and regi stered by the electro nic con trol unit .
Crash severity depends on speed and dece leration as well as the
mass and st iffness of t he vehicle or object invo lved in the crash.
When t he elec tr on ic contro l unit registers a low seve rity crash and
the safety belt is being used, the airbag wi ll not deploy . If the safety
belt is not being used, th e fi rst stage de ploys, foll ow ed by the
second stage after a much later time in t he crash sequence . .,,_
