Cabin lighting activation and battery drain prevention on the 2023 Subaru Impreza are regulated by overhead console manual switches, body control module timer logic, and automatic battery saver relays.
How to Fix It:
-
Set Dome Light to Door Mode: Slide the overhead console light switch to the middle position (Door icon) so lights illuminate automatically when any door is opened.
-
Turn Off Lights Manually: Slide the switch to the "OFF" position if you need to keep doors open for extended periods without draining the 12V battery.
-
Rely on Battery Saver: Rest assured that the vehicle's automatic battery saver feature will shut off interior lights after a set period if a door or trunk is left ajar accidentally.
