Understanding Your Chevy Tahoe Automatic Headlight System morsunled.wordpress.com

This leads us to the vital role of the driver and manual controls. The rotary light switch on your Tahoe’s turn stalk will have an “AUTO” position. For the system to function, the switch must be set here. The other positions—Off, Parking Lamps, and On—allow you to bypass the automation completely. It is a critical safety habit to leave your switch in AUTO at all times. Yet, you must remain proactive. If your wipers are on due to rain or snow, manually rotate the switch to the “On” position to ensure your tail lights and headlights are fully illuminated, making you far more visible from behind—a requirement by law in many states.
