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 malfunc-
tion. 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
system'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-fac-
ing child restraint, or a booster seat is
detected. The PASSENGER AIRBAG OFF
indicator lamp will illuminate and stay on to
remind you that the passenger's side front
airbag is disabled (see the following table).

Volvo recommends that children always be properly
A
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
01 Safety
Occupant Weight Sensor
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.
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 person 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
passenger's seat, but the PASSENGER
AIRBAG OFF indicator lamp is on, it is possi-
ble that the person isn't sitting properly in the
seat. If this happens:
1. Turn the vehicle off and ask the person to
place the seat back in an upright position.
2. Have the person sit upright in the seat,
centered on the seat cushion, with the
person's legs comfortably extended.
3. Restart the vehicle and have the person
remain in this position for about two
minutes. This will allow the system to
detect that person and enable the pas-
senger's frontal airbag.
4. If the PASSENGER AIRBAG OFF indica-
tor lamp remains on even after this, the
