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 65).
Switch off the ignition (page 40).
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 40).

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 65).
Switch off the ignition (page 40).
Have the front passenger vacate the seat and exit the vehicle.
Adjust the seat in a height position (page 44).
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 40).
