Occupant Weight Sensor - Volvo C70 Owner's Manual

Disabling the passenger's side front
airbag
Occupant Weight Sensor (OWS) indicator light
Volvo recommends that ALL occupants
(adults and children) shorter than 4 feet 7
inches (140 cm) be seated in the rear seat of
any vehicle with a passenger's side front air-
bag, and be properly restrained. Children
should always be seated in child restraints
appropriate for their size and weight. See
also the child safety recommendations
beginning on page 30.
The Occupant Weight Sensor (OWS) is
designed to meet the regulatory require-
ments of Federal Motor Vehicle Safety Stan-
dard (FMVSS) 208 and is designed to disable
(will not inflate) the passenger's side front air-
bag under certain conditions.
The OWS works with sensors that are part of
the front passenger's seat and seat belt. The
sensors are designed to detect the presence
of a properly seated occupant and determine
if the passenger's side front airbag should be
enabled (may inflate) or disabled (will not
inflate).
The OWS will disable (will not inflate) the pas-
senger's side front airbag when:
• the front passenger's seat is unoccupied,
or has small/medium objects in the front
seat,
• the system determines that an infant is
present in a rear-facing infant seat that is
installed according to the manufacturer's
instructions,
• the system determines that a small child is
present in a forward-facing child restraint
that is installed according to the manufac-
turer's instructions,
• the system determines that a small child is
present in a booster seat,
• a front passenger takes his/her weight off
of the seat for a period of time,
• a child or a small person occupies the
front passenger's seat.
01 Safety

Occupant Weight Sensor

The OWS uses a PASSENGER AIRBAG OFF
indicator lamp which will illuminate and stay
on to remind you that the passenger's side
front airbag is disabled. The PASSENGER
AIRBAG OFF indicator lamp is located in the
overhead console, near the base of the rear-
view mirror.
NOTE
The PASSENGER AIRBAG OFF indicator
lamp will illuminate for a short period of time
when the ignition is turned on to confirm it is
functional. When the front passenger's seat
is not occupied (empty seat) or in the event
that the passenger's side front airbag is
enabled (may inflate), the PASSENGER
AIRBAG OFF indicator lamp will be off.
However, if a fault is detected in the system:
• The OWS indicator light will stay on
• The SRS warning light (see page 17) will
come on and stay on
The message PASS. AIRBAG OFF SERVICE
URGENT will be displayed in the information
display.
