Front Passenger Airbag
Enabled
See Operator’s ManualFront 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. Objects on the seat or
forces acting on the seat may
make the system sense sup-
plemental weight.Stop the vehicle in a safe location as soon as possible and check the front
passenger seat for the following:
Apply the parking brake (page 67).
Switch off the ignition (page 42).
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 bag on the back of the front passenger 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 recog-
nize 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 switch
on the ignition (
page 42).

Front Passenger Airbag
Disabled
See Operator’s ManualFront 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:
Apply the parking brake (page 67).
Switch off the ignition (page 42).
Have the front passenger vacate the seat and exit the vehicle.
Adjust the seat in a height position (page 46).
Make sure that no objects which apply forces to the seat are present
(e.g. objects such as books, briefcases etc. lodged underneath, behind
or around the seat). Such forces may cause the system 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 switch
on the ignition (
page 42).
