airbag
activated
see Oper.’s Man.
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 pas-
senger seat is empty. Objects on the seat
or forces acting on the seat may make the
system sense supplemental weight.
Stop the vehicle in a safe location as soon
as possible and check the following:
Make sure that there is nothing be-
tween seat cushion and child seat and
check installation of the child seat.
Make sure that no objects applying
supplemental weight onto the seat are
present. The system may recognize
such supplemental weight and sense
that an occupant on the front passen-
ger seat is of a heavier weight than ac-
tually present.
