Occupant weight sensor
The Occupant Weight Sensor (OWS) is designed to meet the regulatory require-ments of Federal Motor Vehicle SafetyStandard (FMVSS) 208 and is designed todisable (will not inflate) the passenger's sidefront airbag under certain conditions.
Occupant Weight Sensor (OWS) indicator light
Disabling the passenger's side front airbag
Volvo recommends that ALL occupants (adults and children) shorter than 140 cm(4 feet 7 inches) be seated in the back seat ofany vehicle with a front passenger side airbagand be properly restrained for their size andweight. The OWS works with sensors that are part of the front passenger's seat and seat belt. Thesensors are designed to detect the presence of a properly seated occupant and determine ifthe passenger's side front airbag should beenabled (may inflate) or disabled (will notinflate). 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 frontseat,
the system determines that an infant ispresent in a rear-facing infant seat that isinstalled according to the manufacturer'sinstructions,
the system determines that a small child ispresent in a forward-facing child restraintthat is installed according to the manufac-turer's instructions,
the system determines that a small child ispresent in a booster seat,
a front passenger takes his/her weight offof the seat for a period of time,
a child or a small person occupies thefront passenger's seat.
The OWS uses a PASSENGER AIRBAG OFFindicator lamp which will illuminate and stayon to remind you that the passenger's sidefront airbag is disabled. The PASSENGERAIRBAG OFF indicator lamp is located in theoverhead console, near the base of the rear-view mirror.
NOTE
When the ignition is switched on, the OWS indicator light will illuminate for sev-eral seconds while the system performs aself-diagnostic 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 stay on and a text message will be dis-played.
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, theSRS system and Occupant Weight Sensorshould be inspected by a trained and quali-fied Volvo service technician as soon aspossible.

WARNING
Never try to open, remove or repair any components 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 notbe modified in any way. This couldreduce pressure on the seat cushion,which might interfere with the OWSsystem's function.

Volvo recommends that children always be properly restrained in appropriate child restraints in the rear seats.Do not assume that the passenger's side front airbag is dis-abled unless the PASSENGER AIRBAG OFF indicator lampis lit. Make sure the child restraint is properly installed. Ifthere is any doubt as to the status of the passenger's sidefront airbag, move the child restraint to the rear seat.
The OWS is designed to enable (may inflate) the passenger's side front airbag in the eventof a collision anytime the system senses that aperson of adult size is sitting properly in thefront passenger's seat. The PASSENGER AIR-BAG OFF indicator lamp will be off andremain off. If a person of adult size is sitting in the front passenger's seat, but the PASSENGER AIR- BAG OFF indicator lamp is on, it is possiblethat the person isn't sitting properly in theseat. If this happens:
Turn the vehicle off and ask the person toplace the backrest in an upright position.
Have the person sit upright in the seat,centered on the seat cushion, with theperson's legs comfortably extended.
Restart the vehicle and have the personremain in this position for about twominutes. This will allow the system todetect that person and enable the pas-senger's frontal airbag.
If the PASSENGER AIRBAG OFF indica-tor lamp remains on even after this, theperson should be advised to ride in therear seat.
This indicates limitations in OWS classifica-tion capability. It does not indicate OWS mal-function.ModificationsIf you are considering modifying your vehiclein any way to accommodate a disability, forexample by altering or adapting the driver's orfront passenger's seat(s) and/or airbag sys-tems, please contact Volvo at: In the United StatesVolvo Car USA, LLCCustomer Care Center
