The front-passenger air bag is disabled during the journey even
though an adult or a person larger than a certain size is occupying
the front-passenger seat. If additional forces are applied to the
seat, the weight the system detects may be too low.
X Pull over and stop the vehicle safely as soon as possible, paying
attention to road and traffic conditions.
X Apply the parking brake.
X Switch off the ignition.
X Have the occupant get out of the vehicle.
X Make sure that the seat is unoccupied and has no objects placed
on it, close the front-passenger door, and switch on the ignition.

multifunction display and check the following:

display. Wait for a period of at least 60 seconds until the
necessary system checks have been completed and to make

occupied again. Whether the 42 indicator lamp
remains lit or goes out depends on how OCS classifies the
occupant.
