head restraints. Head restraints are intend-
ed to help reduce injuries during an acci-
dent.

Front passenger
airbag
activated
See Operator’s Manual
Front passenger front air bag is
activated while driving even
though a child, small individual,
or object below the system’s
weight threshold is on the front
passenger seat, or the front
passenger seat is empty. Ob-
jects on the seat or forces act-
ing on the seat may make the
system sense supplemental
weight.
Stop the vehicle in a safe location as soon as possible and check the
front passenger seat for the following:
Switch off the ignition (
page 36).
Open the front passenger door.
Remove child and child restraint from front passenger seat and
properly secure the child in rear seat employing the child restraint
if necessary.
Remove any other items from on and around the front passenger
seat and make sure the storage pocket on the back of the front pas-
senger seat is empty.
Make sure that no objects which apply forces to the seat are
present (e.g. objects such as books, briefcases etc. lodged behind
or around the seat, head restraints pushing against roof etc.). The
system may recognize such forces as supplemental weight and
sense that an occupant on the front passenger seat is of a greater
weight than actually present.
Keep the seat unoccupied, close the front passenger door and turn
on the ignition (
page 36).
