Manual
The front-passenger air bag is deactivated 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 system may interpret the occupant's weight as lower
than it actually is.

Pull over and stop the vehicle safely as soon as possible, paying
attention to road and traffic conditions.

Make sure that no objects are exerting force on the seat, e.g.
books, bags etc. lying under, behind or beside the seat.

it actually is.

Keep the seat unoccupied, close the front-passenger door and
switch on the ignition.

display messages must not appear in the
multifunction display. Wait for a period of at least 60 seconds
until the necessary system checks have been completed and to
make sure that the display messages do not appear in the
multifunction display.
If these conditions are met, the front-passenger seat can be
occupied again. Whether the 42 indicator lamp
remains lit or goes out depends on how OCS classifies the
occupant.
If the conditions are not met, the system is not operating correctly.
