2006 VOLVO V70
Disabling the passenger's side front airbag
Volvo recommends that ALL occupants (adults and children) shorter than four feet seven inches (140
cm) be seated in the back seat of any vehicle with a front passenger side airbag, and be properly
restrained for their size and weight. See also the child safety recommendations on page 21.
The passenger's side front airbag is automatically enabled/disabled by the Occupant Weight Sensor
(OWS), a system that monitors the weight of the person or object in the front passenger's seat. The
system consists of a silicone-filled bag located under the padding in the front passenger's seat cushion, a
control module located under this seat, and a seat belt tension sensor, located on the outboard side of the
seat.
The OWS system continuously monitors the pressure on the front passenger's seat cushion and the
tension applied to the seat belt. Based on this data, OWS assesses the weight of the occupant or object in
the front passenger's seat. This information is transmitted to the SRS system control module, which
enables or disables the passenger's side front airbag accordingly, as indicated in the table below.
If the system is functioning normally, the status of the front passenger's side airbag (enabled/disabled)
will be shown by the OWS indicator light as explained in the table to the right. The OWS indicator light
is separate and in addition to the SRS warning light in the instrument panel.
NOTE: When the ignition is switched on, the OWS indicator light will go on for up to 10 seconds while
the system performs a self-diagnostic test and then go out.
However, if a fault is detected in the system:
● The OWS indicator light will stay on
● The SRS warning light (see page 5) will come on and stay on
● The message PASS. AIRBAG OFF SERVICE URGENT will be displayed in the information display.
