Seats & Safety System
Front passenger seat adult occupants
who are properly seated and wearing the
seat belt properly, should not cause the
passenger air bag to be automatically
turned OFF. For small adults it may be
turned OFF, however, if the occupant
does not sit in the seat properly (for
example, by not sitting upright, by sitting
on the edge of the seat, or by otherwise
being out of position), this could cause
the sensor to turn the air bag OFF.
You will find the "PASSENGER AIR BAG
OFF" indicator on the overhead console.
This system detects the conditions 1-4
in the following table and activates or
deactivates the front passenger air bag
based on these conditions.
Always be sure that you and all vehicle
occupants are seated properly and
wearing the seat belt properly for the
most effective protection by the air bag
and the seat belt.
Never install a Child Restraint System in
the front passenger's seat. If you should
install a CRS (Child Restraint System)
inevitably, use a forward-facing CRS with
3-point ALR safety seat belt and adjust
the front passenger's seat as far to the
rear as possible. If the PASSENGER AIR
BAG "OFF" indicator is OFF after a CRS
(Child Restraint System) is equipped,
the front passenger's airbag is operating
so you should install the CRS in the rear
seats of the vehicle immediately.

The OCS may not function properly if the
passenger takes actions which can affect
the classification system. These include:
Failing to sit in an upright position.
Leaning against the door or center
console.
Sitting towards the sides of the front
of the seat.
Putting their legs on the dashboard or
resting them on other locations which
reduce the passenger weight on the
front seat.
Wearing the seat belt improperly.
Reclining the seatback.
Wearing a thick cloth like ski wear or
hip protection wear.
Putting an additional thick cushion on
the seat.
Putting electrical devices (for
example, notebook, satellite radio) on
the seat with inverter charging.
