Volvo 2009 S60 - Manual (Page 26)

01 Safety
Occupant Weight Sensor (OWS) 01
26
WARNING
If a fault in the system is detected and indi-
cated as explained on the previous page, 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 Occu-
pant Weight Sensor should be inspected by
a trained and qualified Volvo service tech-
nician 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 an authorized Volvo serv-
ice 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 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 pas-
senger's side front airbag is disabled unless the
PAS-
SENGER 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 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:
• 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 indica-
tor lamp remains on even after this, the
person should be advised to ride in the rear
seat.
