- Children must never be allowed in the front passenger's seat. Volvo recommends that ALL occupants (adults and
children) shorter than 4 feet 7 inches (140 cm) be seated in the back seat of any vehicle with a passenger -side front
airbag. See page 20
for guidelines.
- Occupants in the front passenger's seat must never sit on the edge of the seat, sit leaning toward the instrument
panel or otherwise sit out of position.
- The occupant's back must be as upright as comfort allows and be against the seat back with the seat belt properly
fastened.
- Feet must be on the floor, e.g., not on the dash, seat or out of the window.
WARNING!
- No objects or accessory equipment, e.g. dashboard covers, may be placed on, attached to, or installed near the air
bag hatch (the area above the glove compartment) or the area affected by airbag deployment (see the illustration on
page 6
).
- There should be no loose articles, e.g. coffee cups, on the floor, seat, or dashboard area.
- Never try to open the airbag cover on the steering wheel or the passenger's side dashboard. This should only be
done by a trained and qualified Volvo service technician.
Failure to follow these instructions can result in injury to the vehicle occupants.

Occupant Weight Sensor (OWS) indicator light
Disabling the passenger's side front airbag
Volvo recommends that ALL occupants (adults and children) shorter than four feet seven inches (140 cm) be seated in
the back seat of any vehicle with a front passenger side airbag, and be properly restrained for their size and weight.
See also the child safety recommendations on page 20
.
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 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 to the right.
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:

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.
WARNING!
- 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 authorized 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.
pg. 11 Safety
WARNING!
Keep the following points in mind with respect to the OWS system. Failure to follow these instructions could
adversely affect the systemÕs function and result in serious injury to the occupant of the front passengerÕs 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 passengerÕs 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 20
).
- No objects should be placed under the front passengerÕs seat. This could interfere with the OWS systemÕs
function.
