The courtesy lights work for the timed period and controlled manually, but the timing function does not stop when the ignition is switdhed on.

When one of the side doors is opened, the courtesy light is turned on for a period of 3 minutes and the lights are switched on/off gradually (dimming). When the car is unlocked after activation of the remote control, the courtesy light is switched on for a period of 15 seconds, which is interrupted by the ignition ON signal. If the ignition ON signal is present following the opening of a door, the courtesy lights come on.
