Cabin illumination management and overhead lighting control on the 2023 Cadillac CT5 are regulated by overhead console touch buttons, body control module logic, and interior LED circuits.
How to Fix It:
-
Press Overhead Buttons: Tap the individual reading light buttons on the overhead console to manually turn specific cabin lights on or off.
-
Enable Door Activation: Press and hold the door icon button until it lights up to ensure dome lights automatically turn on whenever doors open.
-
Adjust Brightness: Use the instrument panel dimmer dial located near the headlight controls to adjust overall interior lighting intensity.
