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 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.

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 air-
bag, 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 AIR-
BAG 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 AIR-
BAG 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,
centered on the seat cushion, with the per-
son'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 person and enable the pas-
senger's frontal airbag.
•
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.
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 sys-
tems, please contact Volvo at:
