the multifunction display and check the following:
Seat unoccupied and ignition switched on:
R the 00050006 indicator lamp must light up and remain lit. When
the indicator lamp is on, OCS (Occupant Classification System)
has disabled the front-passenger air bag (Y page 48).
R the Front Passenger Airbag Enabled See Operator's Manual or
