168 Airb a g sys tem
- Improper repair or disassembly of the
front passenger and driver seat will pre-
vent the Advanced Airbag System from
functioning properly.
- Repairs to the front passenger seat must
be performed by qualified and properly
trained workshop personnel.
- Never remove the front passenger or
dr iver seat from the veh icle .
- 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-sens ing mat and send the
wrong info rmation to the airbag control
unit.
- Never store items under the front pas·
senger seat. Parts of the Advanced Air-
bag System under t he passenge r seat
cou ld be damaged, prevent ing them and
the airbag system from working proper-
ly.
- Never place seat covers or replacement
upholstery that have not been specifical-
ly approved by Audi on the front seats.
- Seat covers can prevent the Advanced
Airbag System from recognizing child re-
straints or occupants on the front pas-
senger seat and prevent the side airbag
in the seat backrest from deploy ing prop-
erly.
- Never use cush ions, pillows, blankets or
similar items on the front passenger
seat. The add itiona l padd ing will prevent
the weight-sensing mat in the seat from
accu rately reg iste ring the child restra int
or person on the seat and prevent the
Advanced Airbag System from function-
ing properly .
- If you must use a child restra int on the
front passenger seat and the ch ild re-
straint manufacturer's instructions re-
qu ire the use of a towel, foam cushion or
something else to properly pos ition the
child restraint, make certain that the
PASSENGER AIR BAG OFF light comes
on and stays on whenever the ch ild re·
straint is installed on the front passen-
ger seat.
- If the PASSENGER AIR BAG OFF light
does not come on and stay on, immed i-
ately insta ll child restrain t in a rear se at-
ing position and have the airbag system
inspected by your authorized Audi dealer.
How the Advanced Airbag System
components work together
The front Advanced Airbag System and the
s ide airbags supp lement the protection of-
fered by the front three-point safety belts
with pretensioners and load limiters and the
adjustable head restraints to help redu ce the
risk of injury in a wide range of accident and
crash situations. Be sure to read the impor -
tant information about safety and heed the
WARNINGS in this chapter.
Deployment of the Adv a need Airbag System
and the activation of the safety belt preten-
sioners depend on the deceleration measured
by the crash sensors and registered by the
electron ic control unit. The amount of infla-
tion of the front airbags can a lso be adapted
to the front seat pos ition, depending on the
distance between the respect ive front seat
and the steer ing wheel or instrument panel as
registered by sensors in the seats. Crash se·
verity depends on speed and deceleration as
well as the mass and st iffness of the vehicle
or object involved in the crash .
On the passenger side, regardless of safety
belt use, the airbag will be tu rned off if the
we ight on the passenger seat is less than the
amount programmed in the electronic control
unit. The front airbag on the passenger side
will a lso be turned off if one of the child safe -
ty seats that has been certified under Federal
Motor Vehicle Safety Standard 208 has been
recogni zed on the seat . The
