Occupant safety
When the OCS senses that the front passen-
ger seat occupant is classified as being up
to or less than the weight of a typical
12-month-old child in a standard child re-
straint, the PASS AIR BAG OFF lamp will illu-
minate when the engine is started and
remain illuminated, indicating that the front
passenger front air bag is deactivated.
When the OCS senses that the front passen-
ger seat is classified as being empty, the
PASS AIR BAG OFF lamp will illuminate
when the engine is started and remain illu-
minated, indicating that the front passenger
front air bag is deactivated.
When the OCS senses that the front passen-
ger seat occupant is classified as being
heavier than the weight of a typical
12-month-old child seated in a standard
child restraint or as being a small individual
(such as a young teenager or a small adult),
the PASS AIR BAG OFF lamp will illuminate
for approximately six seconds when the en-
gine is started and then, depending on occu-
pant weight sensor readings from the seat,
remain illuminated or go out. With the PASS
AIR BAG OFF lamp illuminated, the front
passenger front air bag is deactivated. With
the PASS AIR BAG OFF lamp out, the front
passenger front air bag is activated.
When the OCS senses that the front passen-
ger seat occupant is classified as an adult or
someone larger than a small individual, the
PASS AIR BAG OFF lamp will illuminate for
approximately six seconds when the engine
is started and then go out, indicating that
the front passenger front air bag is activat-
ed.
If the PASS AIR BAG OFF lamp is illuminated,
the front passenger front air bag is deacti-
vated and will not be deployed.
If the PASS AIR BAG OFF lamp is not illumi-
nated, the front passenger front air bag is
activated and will be deployed:
ț in the event of certain frontal impacts
ț if impact exceeds a preset deployment
threshold
ț independently of the side impact air
bags.
If the front passenger front air bag is de-
ployed, the rate of inflation will be influ-
enced by:
ț the rate of relevant vehicle deceleration
as assessed by the air bag control unit
ț front passenger's weight category as
identified by the Occupant Classification
System (OCS).
