Front passenger
airbag deactivated
See Operator’s Manual
Air bag is deactivated while 
driving even though an 
adult or someone larger 
than a small individual is 
occupying the front pas-
senger 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 following:
Do not lean on armrests or lift yourself up using han-
dle over the door.
Adjust the seat in a height position (
page 38).
Make sure that no objects which apply forces to the 
seat are present (e.g. objects such as books, brief-
cases 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.
Re-position yourself.
Sit properly belted in a nearly upright position with 
your back against the seat backrest.
If performing any of the above corrective steps is 
successful, the message 
Front passenger airbag 
activated
 will appear in the multifunction display, 
confirming the situation has been remedied.
