Volvo recommends that ALL occupants
(adults and children) shorter than 4 feet
7 inches (140 cm) be seated in the rear seat
of any vehicle with a passenger's side front
airbag, and be properly restrained. Children
should always be seated in child restraints
appropriate for their size and weight. For
child safety recommendations, see
page 38.
The Occupant Weight Sensor (OWS) is
designed to meet the regulatory requirements
of Federal Motor Vehicle Safety Standard
(FMVSS) 208 and is designed to disable (will
28
not inflate) the passenger's side front airbag
under certain conditions.
The OWS works with sensors that are part of
the front passenger's seat and seat belt. The
sensors are designed to detect the presence
of a properly seated occupant and determine
if the passenger's side front airbag should be
enabled (may inflate) or disabled (will not
inflate).
The OWS will disable (will not inflate) the pas-
senger's side front airbag when:
•
the front passenger's seat is unoccupied,
or has small/medium objects in the front
seat,
•
the system determines that an infant is
present in a rear-facing infant seat that is
installed according to the manufacturer's
instructions,
•
the system determines that a small child
is present in a forward-facing child
restraint that is installed according to the
manufacturer's instructions,
•
the system determines that a small child
is present in a booster seat,
•
a front passenger takes his/her weight off
of the seat for a period of time,
•
a child or a small person occupies the
front passenger's seat.
The OWS uses a PASSENGER AIRBAG OFF
indicator lamp which will illuminate and stay
on to remind you that the passenger's side
front airbag is disabled. The PASSENGER
AIRBAG OFF indicator lamp is located in the
overhead console, near the base of the rear-
view mirror.
NOTE
The PASSENGER AIRBAG OFF indicator
lamp will illuminate for a short period of
time when the ignition is turned on to con-
firm it is functional. When the front pas-
senger's seat is not occupied (empty seat)
or in the event that the passenger's side
front airbag is enabled (may inflate), the
PASSENGER AIRBAG OFF indicator lamp
will be off.
However, if a fault is detected in the sys-
tem:
•
The OWS indicator light will stay on
•
The SRS warning light (see page 23) will
come on and stay on
•
The message PASS. AIRBAG OFF
SERVICE URGENT will be displayed in
the information display.
