The Body Control Module (BCM) has direct control over the majority of the vehicle's courtesy lamps. The BCM will illuminate the courtesy lamps under any of the following conditions:

- Any door is ajar.
- The courtesy lamp switch on the instrument panel is closed.
- A Remote Keyless entry unlock message is received. If the interior lamps are left on after the ignition is turned off, the BCM will turn them off after 1 hour or until either the dome lamp switch or door ajar switch changes state.
