restraints or occupants on the front passen
ger seat and prevent the side airbag in the
seat backrest from deploying properly.
- 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 accu
rately registering the child restraint or per
son 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 man
ufacturer'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 pas
senger seat.
- If the
PASSENGER AIR BAG OFF light does
not come on and stay on, immediately in
stall child restraint in a rear seating 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 side
airbags supplement the protection offered by the
front three-point safety belts with pretensioners
and load limiters and the adjustable head re
straints to help reduce the risk of inju ry in a wide
range of accident and crash situations. Be sure to
read the important information about safety and
heed the WARNINGS in this chapter.
Deployment of the Advanced Airbag System and
the act ivation of the safety be lt pretensioners de
pend on the deceleration measured by the crash
sensors and regis tered by the electronic control
unit . Crash severity depends on speed and decel
eration as well as the mass and stiffness of the
vehicle or object involved in the crash .
On the passenger side, regardless of safety belt
use, the airbag will be turned off if the weight on
the passenger seat is less than the amount pro grammed in the elect ronic control unit. The front
Airbag system
airbag on the passenger side will also be turned
off if one of the child safety seats that has been
certified under Federal Motor Vehicle Safety
Standard 208 has been recognized on the seat.
The
PASSENGER AIR BAG OFF light comes on
and stays on to tell you when the front Advanced
Airbag on the passenger side has been turned off

some important things to know .
_&. WARNING
To reduce the risk of injury when an airbag in
flates, always wear safety belts properly.
- If you are unrestrained, leaning forward, sit
ting sideways or out of position in any way,
your risk of injury is much higher.
- You will also receive serious injuries and
could even be killed if you are up against the
airbag or too close to it when it inflates -
even with an Advanced Airbag

tional protection for the chest and face of the
driver and the front seat passenger when:
