Possible cause/consequence
USA only:
The front 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.
Possible solution
X
Stop the vehicle in a safe location as soon as
possible.
X
Engage the parking brake.
X
Switch off the ignition.
X
Have the front passenger vacate the seat and
exit the vehicle.
X
Adjust the seat height to a higher position
( Y page 97).
X
Make sure 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.
X
Keep the seat unoccupied, close the front
passenger door and switch on the ignition.
Monitor the 59 indicator lamp in the
center console ( Y page 56) and the multifunction
display in the instrument cluster (
