Occupant Weight Sensor

WARNING
•
If a fault in the system is detected and
indicated as explained, be aware that
the passenger's side front airbag will
not deploy in the event of a collision.
•
In this case, the safety systems 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.
Maintenance or repairs should only be
carried out by 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 sys-
tem's function.
The OWS is designed to disable (will not inflate)
the passenger's side front airbag when a rear
facing infant seat, a forward-facing child
restraint, or a booster seat is detected. The
PASSENGER AIRBAG OFF indicator lamp will
26
illuminate and stay on to remind you that the
passenger's side front airbag is disabled (see
the following table).

A Volvo recommends that children always be properly
restrained in appropriate child restraints in the rear seats.In
rare situations when the seat belt is not properly fastened,
some child restraints may not be detected by the OWS
because there is very little weight on the vehicle seat cush-
ion. In these cases the passenger's side front airbag may be
disabled, but the PASSENGER AIRBAG OFF indicator lamp
will not be lit. 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 (turn the vehicle off, remove the child restraint from
the vehicle and reinstall the restraint following the child
restraint manufacturer's instructions) and that the
PASSENGER AIRBAG OFF indicator lamp is on, or move
the child restraint to the rear seat.

should be advised to ride in the rear seat.
