Possible solution
Front passenger
airbag
deactivated
See Operator’s Manual
Front passenger front air bag is
deactivated while driving even
though an adult or someone
larger than a small individual is
occupying the front passenger
seat. Forces acting on the seat
may make the system sense a
decrease in 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).

Have the front passenger vacate the seat and exit the vehicle.

Adjust the seat in a height position (
page 41).

Make sure that no objects which apply forces to the seat are
present (e.g. objects such as books, briefcases etc. lodged under-
neath, behind or around the seat). Such forces may cause the sys-
tem to sense that an occupant of a lesser weight than actually
present is on the front passenger seat.

Keep the seat unoccupied, close the front passenger door and turn
on the ignition (
page 36).
