Possible cause/consequence
Possible solution
Front passenger
airbag enabled
See Oper. Manual
Front 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 pas-
senger seat is empty. Objects
on the seat or forces acting on
the seat may make the system
sense supplemental 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 315).

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 emp-
ty.

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 recognize 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 315).
Monitor the 59indicator lamp right of the instrument cluster
(
page 53) and the multifunction display in the instrument cluster
(page 241) for the following:
