Interior Lighting Delay

The purpose of the interior lighting delay feature is to provide temporary illumination of the interior lamps after doors are opened, then closed. The interior lighting delay feature will keep the interior lamps on for a period of up to 25 seconds, or until the ignition cycles from OFF, or the vehicle is locked using the remote keyless entry (RKE) transmitter.

Illuminated Entry

The illuminated entry requests the interior lamps to be illuminated when the ignition is off and the RKE transmitter unlock button is pressed. The illuminated entry requests the interior lamps off after 25 seconds elapse, the ignition is switched to ON, or when the RKE transmitter lock is pressed.

Illuminated Exit

The illuminated exit requests the interior lamps be illuminated for 25 seconds when all doors are closed and the ignition key is removed from the ignition lock cylinder. The illuminated exit will request the interior lamps be deactivated when any door becomes ajar, the key is inserted into the ignition lock cylinder, or 25 seconds expire.

Theater Lighting

The theater lighting option ramps up the interior lamps over 0.7 seconds when interior lamp activation is requested. The theater lighting feature ramps down the interior lamps over 1.7 seconds when interior lighting deactivation is requested by any other feature other than the panic alarm or battery saver.

Interior Lamp Arbitrator

The interior lamp arbitrator (located in the SJB) chooses between the interior lighting, interior mode, interior lighting delay, illuminated entry, illuminated exit and battery saver to determine which feature has precedence of activating and deactivating the interior lamps. The features are prioritized as follows: battery saver, interior mode, interior lighting, interior light delay, illuminated entry, and illuminated exit.

Battery Saver

The battery saver is internal to the SJB and provides automatic shut-off of the demand lamps (vanity lamps and map lamps) and interior lamps after a period of 10 minutes has elapsed in order to save battery voltage. A timer in the SJB is started when the ignition key is turned to the OFF position. When the time-out period for the lamps has elapsed, the voltage is automatically shutoff to the lamps by the battery saver. While battery saver has voltage disabled, if the ignition is turned to any position other than OFF, any door or liftgate becomes ajar or the unlock button of the remote transmitter is pressed, the battery saver will restore voltage and start the timer again. The amount of time that is required to elapse before the voltage to the lamps is shut off is 10 minutes.
