Front Passenger
Airbag Disabled
See Operator's
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.
X Pull over and stop the vehicle safely as soon as possible, paying
attention to road and traffic conditions.
X Engage the parking brake.
X Switch off the ignition.
X Have the occupant get out of the vehicle.
X Set the seat higher ( Y page 100).
X Make sure that no objects are exerting force on the seat, e.g.
books, bags etc. lying under, behind or beside the seat.
These forces may otherwise cause the system to detect too low
a weight and interpret the seat occupant's weight as less than
it actually is.
X Keep the seat unoccupied, close the front-passenger door and
switch on the ignition.
Observe the 42( Y page 45) indicator lamp and the
multifunction display and check the following:
Seat unoccupied and ignition switched on:
R
the 42 indicator lamp must light up and remain lit.
When the indicator lamp is on, OCS (
Y page 45) has deactivated
the front-passenger air bag.
R
the Front Passenger Airbag Enabled See Operator's
Manual or Front Passenger Airbag Disabled See
Operator's Manual 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.
X Visit a qualified specialist workshop immediately.
