The front-passenger air bag is enabled during the journey, even
though: - a child, a small adult or an object weighing less than the system's weight threshold is located on the front-passenger seat. - the front-passenger seat is unoccupied. The system may detect objects or forces applying additional weight on the seat. – Pull over and stop the vehicle safely as soon as possible, paying attention to road and traffic conditions. – Engage the parking brake. – Switch off the ignition. – Open the front-passenger door. – Remove the child and the child restraint system from the frontpassenger seat. – If necessary, secure the child in a child restraint system on a suitable rear seat. – Make sure that there are no objects on the seat adding to the weight. The system may otherwise detect the additional weight and interpret the seat occupant's weight as greater than it actually is. – Keep the seat unoccupied, close the front-passenger door and switch on the ignition. Observe the indicator lamp and the multifunction display and check the following: Seat unoccupied and ignition switched on: - the indicator lamp must light up and remain lit. When the indicator lamp is on, OCS has deactivated the front-passenger air bag. - the Front Passenger Airbag Enabled See Operator's Manual or Front Passenger Airbag Disabl'd 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 fulfilled, the front-passenger seat can be occupied again. Whether the indicator lamp remains lit or goes out depends on how OCS classifies the occupant. If the conditions are not fulfilled, the system is not operating correctly. – Visit a qualified specialist workshop immediately. |
WARNING
If the indicator lamp
remains off even after performing the above corrective steps, do
not have any children 12 years old and under and other small individuals use the
front-passenger
seat until the system has been repaired.
