376 Practical hintsWhat to do if …Display symbol
Display messages
Possible cause
Possible solution
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.
