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
The 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. The 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
Controls and equip-
ment
Safety first
Vehicle operation
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 => page

•
The PASSENGER AIR BAG OFF light comes on and stays on in the
center of the instrument panel => page
230,
fig . 233 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
passenger seat should be turned off or not => page
