How to adjust the left and right of Vios headlights?
2 Answers
The method to adjust the left and right of Vios headlights is: adjust the adjustment screw behind the headlight assembly. Car headlights, also known as car front headlights or car LED daytime running lights, can be maintained by: 1. Regularly check the sealing of the headlights, and replace the sealing ring between the lens and reflector if it is damaged; 2. Regularly clean the reflector, and replace it if it turns black or the brightness decreases; 3. Regularly clean dust and stains on the bulb. Taking the Vios 2021 manual forward version as an example, it is a compact 4-door 5-seater sedan with body dimensions of: length 4435mm, width 1700mm, height 1490mm, and a wheelbase of 2550mm.
I once helped a friend adjust the horizontal position of the Vios headlights, and it turned out to be less difficult than expected. You need to find a flat road to park, facing the car towards a wall, maintaining a distance of a few meters. After opening the hood, locate the horizontal adjustment screw at the back of the headlight, usually a small cross-shaped device. Using a common Phillips screwdriver, turning it clockwise will move the light to the right, while counterclockwise will move it to the left—just turn it a little at a time and then turn off the lights to check the effect. Be careful not to over-adjust, as misaligned lights can affect nighttime visibility and even draw complaints from other drivers. During testing, turn on the low beams to see if the horizontal line formed on the wall is parallel. If you're not familiar with tools, it's advisable to wear gloves to avoid scratches. I always recommend beginners start with simple adjustments and, if unsure, take it to a professional shop.
