Disabling the passenger's side front

Occupant Weight Sensor (OWS) indicator light
Volvo recommends that ALL occupants (adults
and children) shorter than 4 feet 7 inches
(140 cm) be seated in the rear seat of any vehi-
cle 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. See also the child safety rec-
ommendations beginning on page 33.
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
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 manufac-
turer'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 light which will illuminate and
stay on to remind you that the passenger's side
front airbag is disabled. The
PASSENGER
AIRBAG OFF indicator light 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 confirm it
is functional. When the front passenger'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
system:
• The PASSENGER AIRBAG OFF indicator
light will stay on.
• The SRS warning light (see page 20) will
come on and stay on.
• The message PASS. AIRBAG OFF
SERVICE URGENT will be displayed in
the information display.
