1. Prepare:
- Park your car on a level surface facing a wall or garage door about 25-30 feet (7-9 meters) away.
- Make sure your vehicle is in "Park" or "Neutral" with the engine turned off.
2. Headlights:
- Consult your vehicle's owner's manual to locate the headlight adjustment screws or knobs.
- Different vehicles have different adjustment mechanisms, so familiarize yourself with your specific model's instructions.
3. Alignment:
- Stand in front of your vehicle and observe the headlights' beam pattern on the wall or garage door.
- There should be a distinct cutoff line where the light beam meets the darkness.
4. Vertical Adjustment:
- Use the vertical adjustment screw or knob to adjust the cutoff line of the light beam.
- The light should be high enough to illuminate the road ahead but not so high that it blinds oncoming drivers.
5. Horizontal Adjustment:
- Use the horizontal adjustment screw or knob to adjust the left and right positioning of the light beam.
- Aim for the light to be centered on the road ahead, without encroaching on the lanes of oncoming traffic.
6. Double-Check:
- Once you have adjusted your headlights, test them by driving in a dimly lit area or a well-lit parking lot to make sure the alignment is correct.
7. Consult a Professional:
- If you're unsure about the proper adjustment or encounter difficulties, don't hesitate to consult a trusted mechanic or a dealership service department to have your headlights adjusted professionally.
Remember, the specific steps and adjustment locations may vary depending on your vehicle's make and model. Always refer to your vehicle's owner's manual for the most accurate instructions.
