Use the headlight control knob on the left side of the steering column to activate the lights. Set the switch to Auto for automatic headlights, or rotate it to On to illuminate them manually.
The Buick Enclave provides a straightforward lighting setup with an automatic mode that responds to ambient light, plus a manual option for immediate control. This guide walks you through locating the controls, choosing between Auto and manual modes, and using related features like high beams and fog lights. It also covers basic troubleshooting if the lights don’t come on as expected.
Where to find and how to use the headlight controls
Locate the headlight control knob on the dash, to the left of the steering wheel. The dial offers multiple positions, including Auto for automatic operation and On for manual illumination. The following steps outline how to turn on the headlights and select a mode.
- Locate the headlight control knob on the left side of the steering column.
- Rotate the knob to Auto to enable automatic headlights that respond to ambient light.
- Rotate the knob to the On/Headlights position if you want to manually illuminate the headlights regardless of ambient light.
- For parking lights or daytime running lights (if supported in your model), set the knob to the Parking Lights position as needed.
- To activate high beams, use the adjacent turn-signal/stalk control: push the stalk forward to engage high beams; pull it back to return to low beams; a quick pull toward you typically flashes the high beams.
In practice, Auto is convenient for everyday driving, while On gives you direct control if you’re in conditions where you want constant illumination. The parking lights provide a lighter lighting option when parked or in low-traffic situations.
High beams and other lighting features
High beams
High beams are controlled by the left-hand stalk. Engage them by pushing the stalk away from you until it stays in place; return to low beams by pulling the stalk back toward you. A brief pull toward you usually flashes the high beams without leaving them on.
- High beams: Push the stalk away from you to lock them on at high intensity.
- Flash-to-pass: Pull the stalk toward you briefly to momentarily illuminate at high beams.
Using high beams is important for poor visibility or when there are no oncoming vehicles. Remember to switch back to low beams when another vehicle approaches to avoid blinding other drivers.
Fog lights and other optional lighting
Some Enclave models include fog lights activated by a dedicated button on the headlight control assembly or nearby. If your vehicle has fog lights, press the fog icon when visibility is reduced due to fog, rain, or snow.
- Fog lights: Press the dedicated fog light button or rotate the control to the fog position if equipped.
- Daytime Running Lights (DRLs): Many Enclaves operate DRLs automatically when the engine is running; they may differ from headlamps in intensity and purpose.
If your model doesn’t have fog lights, you’ll see no fog-light button. Always refer to your owner’s manual for the exact configuration of your trim year.
Troubleshooting and tips
If the headlights don’t come on when they should, try these quick checks before seeking service:
- Ensure the headlight switch is not set to Off.
- Confirm the switch is in Auto or On, depending on your preference for manual control.
- Check the vehicle’s battery and fuses related to exterior lighting.
- Clean the windshield-mounted sensor area if your Auto headlights aren’t responding; a obstructed sensor can affect automatic operation.
If problems persist, consult your Buick dealer or the owner’s manual for model-year-specific guidance and fuse locations. Modern Enclaves rely on a combination of sensors and body control modules, so persistent issues may require professional diagnostics.
Summary
To turn on headlights in a Buick Enclave, use the left-side headlight control knob. Set it to Auto for automatic operation, or to On for manual illumination. High beams are controlled by the steering stalk (push forward to engage, pull back to return, and pull briefly to flash). If equipped, fog lights have a separate control. In everyday driving, Auto offers convenient, sensor-based lighting, while manual On provides direct control when conditions demand it. Always use appropriate lighting for visibility and safety, and consult the owner’s manual or a Buick dealer if you encounter issues.
