Manual exterior lighting overrides and supplemental fog illumination on the 2023 Cadillac CT5 are governed by dashboard control dials, lighting circuit relays, and body control module switches.
How to Fix It:
-
Turn on Parking Lights: Rotate the headlight switch dial to the parking light symbol to illuminate your exterior side markers and tail lamps without turning on the main headlamps.
-
Activate Headlamps Manually: Rotate the switch fully to the headlamp icon position to keep your low-beam headlights on continuously regardless of outside lighting conditions.
-
Toggle Fog Lights: Press the dedicated fog light button located near the rotary dial to switch on your front fog lamps when driving through heavy mist or low-visibility weather.
