NOTE
When the ignition is switched on, the OWS
indicator 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 stay
on 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 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.
WARNING
•
Never try to open, remove, or repair any
components in the OWS system. This
could result in system malfunction. Main-
tenance 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.

A 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 disabled unless the
PASSENGER AIRBAG OFF indicator lamp is lit. Make sure the
child restraint is properly installed. If there is any doubt as to the
status of the passenger's side front 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 event of a
collision anytime the system senses that a per-
son of adult size is sitting properly in the front
passenger's seat. The PASSENGER AIRBAG
OFF indicator lamp will be off and remain off.
If a person of adult size is sitting in the front pas-
senger's seat, but the PASSENGER AIRBAG
OFF indicator lamp is on, it is possible that the
person isn't sitting properly in the seat. If this
happens:
•
Turn the vehicle off and ask the person to
place the seatback in an upright position.
•
Have the person sit upright in the seat, cen-
tered on the seat cushion, with the person's
legs comfortably extended.
•
Restart the vehicle and have the person
remain in this position for about two minutes.
This will allow the system to detect that per-
son and enable the passenger's frontal air-
bag.
•
If the PASSENGER AIRBAG OFF indicator
lamp remains on even after this, the person
should be advised to ride in the rear seat.
This condition reflects limitations of the OWS
classification capability. It does not indicate OWS
malfunction.
