WARNING
(continued)
•
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
If, in exceptional circumstances, you must install a forward-facing
child
restraint on the front passenger's seat:
•
Always make sure the forward -facing seat has been designed
and certified by its manufacturer for use on a front seat with a
passenger front and side airbag.
•
Never put the forward-facing child restraint up against or very
near the instrument panel.
•
Always move the passenger seat into its rearmost position in
the seat's fore and aft adjustment range, as far away from the
airbag as possible, before installing the forward-facing child
restraint
.
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.
•
Advanced
Airbag
System
components
Th
e
front passenger seat in your vehicle has a
lot
of very important
parts of the Advanced Airbag System in
it
.
These parts include the
weight-sensing
mat,
sensors, wiring, brackets, and more.
Th
e func-
tion
of the system in
the
front
passenger seat is
checked by
the
elec-
tronic control unit when the ignition 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
.
The front
Advanced
Airbag
System
consists
of the
following:
•
Crash sensors
in
the
front of the
vehicle that measure vehicle
acceleration/deceleration
to
provide 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
control unit also "decides"
whether the
safety belt
pretensioners should be activated.
•
An Advanced Airbag with gas generator
for
the driver inside
the
steering wheel hub
.
•
An Advanced Airbag with gas generator inside
the
instrument
panel for the front passenger.
•
A weight-sensing
mat
under
the
upholstery
padding of the
front
passenger seat cushion
that
measures the total weight on the seat.
The
information
registered is
sent
continuously to the
electronic
control unit
to
regulate deployment of
the
front Advanced Airbag on
the passenger
side.
•
An airbag monitoring
system and indicator light
in
the instru
-
ment
cluster
~

•
Th
e
PASSENGER AIR BAG OFF
light comes on and stays on in the
center of
the instrument
panel
~
page 149, fig.
115
and
tells
you
when the front Advanced Airbag on the passenger side has been
turned off.
•
A sensor below 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 -sensing mat help the
control
unit "decide"
whether
the front airbag
for the
front
