Check Engine Warning Light This light illuminates when the engine's Emission Control System requires service. It will also illuminate when the ignition key is in the ON position and the engine is off. Air Bag Readiness Light The air bag system uses a readiness light and a tone to indicate the condition of the system. The readiness light is in the instrument panel. When you turn the ignition key to the ON position, this light will light up for six (6) seconds and then turn off. This indicates that the system is operating normally. NOTE: Regularly scheduled maintenance of the air bag system is not required. If the light fails to illuminate, continues to flash, remains on, or you hear a beeping sound, have the system serviced at your Ford or Lincoln-Mercury dealer immediately. 14
