Dome light delay shutdown function
The dome light off is delayed by ETACS-ECU. The lights off delay time vary according to the conditions. The control details are as follows. The light delay off Yes/NO and delay time can be set with the settings (adjustment function). Refer to ADJUSTMENT PROCEDURES OF SWS FUNCTION in Body Control Systems for adjustment methods and adjustment details (post-adjustment operations).

- The dome light lights up if the ignition switch is at the "LOCK" (OFF) position and either of the doors are opened (either of the door switches: ON). At this time, if all doors are closed (all door switches: OFF) then the light will gradually dim down to lights off in about 30 seconds.

NOTE: When the lights are dimmed and the ignition switch is turned ON or if the door is locked, then the dimming operations stop and the lights are turned OFF.
