The passenger's side front airbag is automatically enabled/disabled by the Occupant Weight Sensor (OWS), a system
that monitors the weight of the person or object in the front passenger's seat. The system consists of a silicone-filled
bag located under the padding in the front passenger's seat Occupant Weight Sensor - disabling the passenger's side
front airbag cushion, a control module located under this seat, and a seat belt tension sensor, located on the outboard
side of the seat.
The OWS system continuously monitors the pressure on the front passenger's seat cushion and the tension applied to
the seat belt. Based on this data, OWS assesses the weight of the occupant or object in the front passenger's seat. This
information is transmitted to the SRS system control module, which enables or disables the passenger's side front
airbag accordingly, as indicated in the table below.
If the system is functioning normally, the status of the front passenger's side airbag (enabled/disabled) will be shown
by the OWS indicator light as explained in the table to the right. The OWS indicator light is separate and in addition to
the SRS warning light in the instrument panel.
NOTE: When the ignition is switched on, the OWS indicator light will go on for up to 10 seconds while the system
performs a self diagnostic test and then go out. However, if a fault is detected in the system:
The OWS indicator light will stay on
The SRS warning light (see page 14) will come on and stay on
The message PASS. AIRBAG OFF SERVICE URGENT will be displayed in the information display.
pg. 19 Occupant Weight Sensor - disabling the passenger's side front airbag
WARNING!
If a fault in the system is detected and indicated as explained on the preceding page, be aware that the passenger's
side front airbag will not deploy in the event of a collision. In this case, the SRS system and Occupant Weight
Sensor should be inspected by a trained and qualified Volvo service technician as soon as possible.
Modifications
If you are considering modifying your vehicle in any way to accommodate a disability, for example by altering or
adapting the driver's or front passenger's seat(s) and/or airbag systems, please contact Volvo at:

1-800-663-8255WARNING!
Never try to open, remove, or repair any components in the OWS system. This could result in system malfunction.
Maintenance or repairs should only be carried out by an a trained and qualified Volvo service technician.
The front passenger's seat should not be modified in any way. This could reduce pressure on the seat cushion,
which might interfere with the OWS system's function.
WARNING!
No objects that add to the total weight on the seat should be placed on the front passenger's seat. If a child is seated
in the front passenger's seat with any additional weight, this extra weight could cause the OWS system to enable the
airbag, which might cause it to deploy in the event of a collision, thereby injuring the child.
The seat belt should never be wrapped around an object on the front passenger's seat. This could interfere with the
OWS system's function.
The front passenger's seat belt should never be used in a way that exerts more pressure on the passenger than
normal. This could increase the pressure exerted on the weight sensor by a child, and could result in the airbag being
enabled, which might cause it to deploy in the event of a collision, thereby injuring the child.
pg. 20 Occupant Weight Sensor - disabling the passenger's side front airbag
WARNING!
Keep the following points in mind with respect to the OWS system. Failure to follow these instructions could
adversely affect the system's function and result in serious injury to the occupant of the front passenger's seat:
The full weight of the front seat passenger should always be on the seat cushion. The passenger should never lift
him/herself off the seat cushion using the armrest in the door or the center console, by pressing the feet on the floor,
by sitting on the edge of the seat cushion, or by pressing against the backrest in a way that reduces pressure on the
seat cushion. This could cause OWS to disable the front, passenger's side airbag.
Do not place any type of object on the front passenger's seat in such a way that jamming, pressing, or squeezing
occurs between the object and the front seat, other than as a direct result of the correct use of the ALR/ELR seat belt
(see page 31
).
No objects should be placed under the front passenger's seat. This could interfere with the OWS system's function.

3. SRS warning light
If this light comes on while the car is being driven, or remains on for longer than approximately 10 seconds
after the car has been started, the SRS system's diagnostic functions have detected a fault in a seat belt lock or
tensioner, a front airbag, side impact airbag, and/or an inflatable curtain. Have the system(s) inspected by a trained and
qualified Volvo service technician as soon as possible.
4. Oil pressure warning light
If the light comes on while driving, stop the car, stop the engine immediately, and check the engine oil level.
If the oil level is normal and the light stays on after restart, have the car towed to the nearest trained and qualified
Volvo service technician. After hard driving, the light may come on occasionally when the engine is idling. This is
normal, provided it goes off when the engine speed is increased.
