The interior lights operate when operated manually, but the timer does not stop when the key is turned on.

When one of the side doors is opened, the courtesy light timer comes on for 3 minutes and light activation/deactivation is gradual (dimmed). When the vehicle is unlocked after operating the remote control, the courtesy light comes on for 15 seconds, which is interrupted by the key ON signal. If the key on signal is present continuously after opening a door, the courtesy lights come on.
