To turn on the headlights on a Chevy Impala, use the headlight control on the left side of the steering column. Depending on your year and trim, you’ll either use a dash-mounted rotary switch (Off/Parking/On/Auto) or a multifunction stalk on the steering column. In most models, setting the control to Auto will illuminate the lights automatically when it’s dark; otherwise, rotate to On to manually activate them.
Where to find and understand the headlight control
Most Impalas place the headlight switch in the lower-left area of the dash. If your model uses a stalk, the left-side turn-signal lever will incorporate the headlight control or a small knob at its end. The exact layout varies by generation, so consult your owner’s manual if you’re unsure.
Model-year variations
Chevrolet began offering automatic headlights on many trims in the mid-2010s. Earlier models rely on a manual switch. If you’re unsure which setup your car has, check the switch labeling (Off, Parking Lights, Headlights, Auto) or refer to the manual for your specific year and trim.
Below is a concise guide to operating the headlights for most Impalas, followed by tips and troubleshooting.
How to turn on the headlights
Follow these steps to activate the lights. The core action is selecting On or Auto on the left-side control.
- Locate the headlight control on the left side of the steering column (dash dial or stalk control).
- Turn the dial from Off to Parking Lights, then to Headlights On. If your model has Auto, switch to Auto to enable automatic activation in low light.
- Drive with the lights on as needed; low beams are typically used at night or in poor weather.
With Auto, the system will switch the headlights on and off based on ambient lighting and speed. If you don’t see lights after selecting Auto, verify the ignition position and that there isn’t another setting overriding the control.
Using high beams and related lighting features
On most Impalas, high beams are controlled via the left-side turn-signal stalk. The standard operation is to push the stalk away to activate high beams; pulling toward you will flash the high beams in emergencies. Some trims also offer fog lights, accessible via a separate button near the headlight switch.
- To flash high beams briefly, pull the stalk toward you and release.
- To leave high beams on continuously, push the stalk away until it locks in place (if your model supports this).
- Use fog lights (if equipped) only when visibility is reduced due to fog, rain, or snow.
Remember to switch back to low beams when meeting oncoming traffic or following another vehicle closely to avoid dazzling other drivers.
Troubleshooting: headlights won’t turn on
If the headlights fail to illuminate, try these checks before seeking service:
- Confirm the headlight switch is set to On or Auto, not Off.
- Check for a blown fuse or relay in the vehicle’s lighting circuit—refer to the owner’s manual for the exact fuse locations.
- Inspect bulbs for burnout; a failed bulb on one side won’t illuminate that side.
- If the problem persists, have a professional diagnose wiring, the headlight switch, or control modules.
In some cases, software updates or part replacements may be required to restore full functionality.
Bottom line
For most Chevrolet Impalas, turning on the headlights is a straightforward task: locate the left-side headlight control and select On or Auto. High beams are typically controlled via the turn-signal stalk. If lights don’t come on, check the switch position, fuses, and bulbs, and seek professional help if needed.
Summary: The headlights are controlled by a left-side switch or stalk; Auto mode may exist depending on year. Use On or Auto to illuminate the headlights, and use the stalk to operate high beams. Troubleshoot fuses and bulbs if lighting fails.
