Interior Lighting Control

The interior light control function provides convenience and security by turning on the interior courtesy lights under several conditions. The following conditions enable the courtesy lamps:
^ A discrete input to the BCM from the door ajar switches
^ If any of the doors are open and the vehicle speed is less than 13 km/h (8 mph)
^ When you close all doors (The lights stay on for 10 seconds or until you turn on the ignition switch: for the first 2 seconds the courtesy lights are at full intensity, then the lights go to step dim for the remainder of the time.)
^ After the ignition switch has been turned off for less than 2 minutes and either you remove the ignition key or you open the doors (The lights turn on for 10 seconds, or until you turn on the ignition switch, or until you cycle a door jamb switch.)
^ If you use the following features on the remote control door lock transmitter:
- Activate the driver door unlock feature
- Activate the trunk release
- Initiate the panic feature

When the driver leaves the vehicle (the ignition switch is turned off for more than 2 minutes), the interior lights are first step dimmed, and then theater dimmed to the off state.
