Occupant Weight Sensor - Volvo XC90 TWIN ENGINE Owner's Manual

Occupant weight sensor

The Occupant Weight Sensor (OWS) is
designed to meet the regulatory require-
ments of Federal Motor Vehicle Safety
Standard (FMVSS) 208 and is designed to
disable (will not inflate) the passenger's side
front airbag under certain conditions.

Volvo recommends that ALL occupants
(adults and children) shorter than 140 cm
(4 feet 7 inches) be seated in the back seat of
any vehicle with a front passenger side airbag
and be properly restrained for their size and
weight.
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.
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
When the ignition is switched on, the
OWS indicator light will illuminate for sev-
eral seconds while the system performs a
self-diagnostic test.
However, if a fault is detected in the system:
The OWS indicator light will stay on.
•
The SRS warning light will come on and
•
stay on and a text message will be dis-
played.
WARNING
If a fault in the system is detected and indi-
cated as described, be aware that the pas-
senger's side front airbag will not deploy in
the event of a collision. In this case, the
SRS system and Occupant Weight Sensor
should be inspected by a trained and quali-
fied Volvo service technician as soon as
possible.
