Possible causes/consequences and M Solutions The front-passenger air bag is enabled during the journey, although: Rthere is a child, a small adult or an object weighing less than the

system's weight threshold is on the front-passenger seat.

Rthe front-passenger seat is unoccupied The system may detect the additional weight of objects on the seat or forces acting on the seat. 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 Open the front-passenger door. X Remove the child and the child restraint system from the front-

passenger seat.

X If necessary, secure the child in a child restraint system on a

suitable rear seat.

X Make sure that no forces are acting on the seat, such as:

Rtrapped books, bags, etc. lying on, behind or beside the seat Rhead restraints pressing against the headliner The system may otherwise detect these forces and interpret the seat occupant's weight as greater 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 indicator lamps (Y page 42) and the multifunction display and check the following: Seat unoccupied and ignition switched on: Rthe 42 indicator lamp must light up and remain lit. 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 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.
