Occupant weight sensor
The Occupant Weight Sensor (OWS) isdesigned to meet the regulatory requirements ofFederal Motor Vehicle Safety Standard (FMVSS)208 and is designed to disable (will not inflate)the passenger's side front airbag under certainconditions.
Occupant Weight Sensor (OWS) indicator light

Disabling the passenger's side front
airbag
Volvo recommends that ALL occupants (adultsand children) shorter than 140 cm (4 feet7 inches) be seated in the back seat of any vehi-cle with a front passenger side airbag and beproperly restrained for their size and weight.
The OWS works with sensors that are part of thefront passenger's seat and seat belt. The sensorsare designed to detect the presence of a properly
seated occupant and determine if the passeng-er's side front airbag should be enabled (mayinflate) 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, orhas small/medium objects in the front seat,
the system determines that an infant is pres-ent in a rear-facing infant seat that is instal-led according to the manufacturer's instruc-tions,
the system determines that a small child ispresent in a forward-facing child restraintthat is installed according to the manufactur-er's instructions,
the system determines that a small child ispresent in a booster seat,
a front passenger takes his/her weight off ofthe seat for a period of time,
a child or a small person occupies the frontpassenger's seat.
The OWS uses a PASSENGER AIRBAG OFFindicator lamp which will illuminate and stay on toremind you that the passenger's side front airbagis disabled. The PASSENGER AIRBAG OFF indi-cator lamp is located in the overhead console,near the base of the rearview mirror.

NOTE
When the ignition is switched on, the OWSindicator light will illuminate for several sec-onds while the system performs a self-diag-nostic test.
However, if a fault is detected in the system:
The OWS indicator light will stay on
The SRS warning light will come on and stayon and a text message will be displayed.

WARNING
If a fault in the system is detected and indi-cated as described, be aware that the pas-senger's side front airbag will not deploy inthe event of a collision. In this case, the SRSsystem and Occupant Weight Sensor shouldbe inspected by a trained and qualified Volvoservice technician as soon as possible.
WARNING
Never try to open, remove or repair anycomponents in the OWS system. Thiscould cause the system to malfunction.Maintenance or repairs should only becarried out by an a trained and qualifiedVolvo service technician.
The front passenger's seat should not bemodified in any way. This could reducepressure on the seat cushion, whichmight interfere with the OWS system'sfunction.

AVolvo recommends that children always be properly restrainedin appropriate child restraints in the rear seats. Do not assumethat the passenger's side front airbag is disabled unless thePASSENGER AIRBAG OFF indicator lamp is lit. Make sure thechild restraint is properly installed. If there is any doubt as to thestatus of the passenger's side front airbag, move the childrestraint to the rear seat.
The OWS is designed to enable (may inflate) thepassenger's side front airbag in the event of acollision anytime the system senses that a per-son of adult size is sitting properly in the frontpassenger's seat. The PASSENGER AIRBAGOFF indicator lamp will be off and remain off.
