When the ignition switch is turned OFF, the courtesy lamps interrupt timer and demand lamps interrupt timer begin their time-out. The interrupt timer is a feature of the lighting control module. Power is available to the lamps during time-out. At the end of the 9-11 minute time-out period, the lighting control module disables power to the courtesy lamps. At the end of the 25-35 minute time-out period, the lighting control module disables power to the demand lamps. The following lamps are affected:

Courtesy Lamps
^ Front door courtesy lamps.
^ Rear reading lamps.
^ Instrument panel courtesy lamps.
^ Front map lamps.
^ Rear door courtesy lamps.
^ Door lock cylinder lamps.

Demand Lamps
^ Glove compartment lamp.
^ Vanity lamps.
^ Luggage compartment lamp.
^ Engine compartment lamp.
^ Rear map lamps.
^ Front map lamps.

Turning the ignition switch to ACC or RUN will terminate the battery saver feature by disabling the interrupt timers and reinstating power to the lamps.

A reset event will set the courtesy lamps interrupt timer to zero. The reset events for the courtesy lamps interrupt timer are as follows:
^ Turning ON the courtesy lamps by using the dome lamp switch.
^ Detecting a change in state in the illuminated entry signal (from either the door handles or the driver door module).
^ Opening any door (as detected by the interior lamp switches).

A reset event will set the demand lamps interrupt timer to zero. The reset events for the demand lamps interrupt timer are as follows:
