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. For child safety recommen- dations, see page 37.

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 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 rearview 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 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.
