218 Display messages Display messages Front Passenger Airbag Disabled See Operator's Manual Possible causes/consequences and M Solutions 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 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 Make sure that the seat is unoccupied and has no objects placed on it, close the front-passenger door, and switch on the ignition. Observe the 42(Y page 42) indicator lamps and the multifunction display and check the following: Seat unoccupied and ignition switched on: Rthe 42 indicator lamp must light up and remain lit. On-board computer and displays When the indicator lamp is on, OCS (Y page 42) has disabled the front-passenger air bag. Rthe display messages Front Passenger Airbag Enabled See Operator's Manual or Front Passenger Airbag Disabled See Operator's Manual cannot 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. G Warning If the 42 indicator lamp remains lit with an adult occupant on the front-passenger seat even after performing the above corrective steps, do not have any passenger use the frontpassenger seat until the system has been repaired.
