See Oper. ManualThe passenger front air bag and
the passenger knee air bag are
activated while driving even
though a child, small individual,
or object below the system’s
weight threshold is on the pas-
senger seat, or the passenger
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 passenger seat for the following:
Switch off the ignition (page 40).
Apply the parking brake (page 55).
Remove child and child restraint from passenger seat.
Make sure that no objects which are applying supplemen-
tal weight onto the seat are present. The system may rec-
ognize such supplemental weight and sense that an
occupant on the passenger seat is of a greater weight
than actually present.
Keep the seat unoccupied, close the passenger door and
switch on the ignition (
page 40).
