The method to adjust the headlight height of Changan CS55 is to rotate the headlight height control button located on the left side of the center console. The functions of vehicle lights are: 1. Accurately illuminate the road ahead to enhance nighttime driving safety; 2. Transmit signals to prevent traffic accidents. Types of automotive lights include: headlights, fog lights, brake lights, daytime running lights, and hazard warning lights. Taking the 2019 Changan CS55 as an example, it is a compact SUV with body dimensions of: length 4500mm, width 1855mm, height 1690mm, wheelbase 2650mm, minimum ground clearance 190mm, and curb weight 1460kg.

I remember adjusting the headlight height on the Changan CS55 was quite simple. I usually drive the older model, where there's a rotary knob marked with numbers from 0 to 3 near the driver's left knee facing the steering wheel. The higher the number, the farther the headlights shine. Whenever the trunk is fully loaded and the rear of the car sags, I turn the knob two notches toward a higher number to prevent the headlights from being too low and affecting visibility. If you can't find this knob in your car, you'll need to open the engine hood and adjust it manually. There are adjustment holes on the back of the headlights—just use a Phillips screwdriver to slowly turn the white plastic gear. It's best to test the projection height against a white wall after dark; otherwise, misalignment could dazzle oncoming drivers, which is dangerous. For those who have modified their headlights, be careful not to exceed the factory height standard, or you might run into issues during annual inspections and have to readjust.

I've spent a lot of time thinking about adjusting headlight height, especially for urban SUVs like the CS55. The dial at the lower left corner of the driver's seat is designed specifically for this purpose. Setting 0 is the lowest and most suitable for an unloaded vehicle, while setting 2 is the safest when carrying family members. Once when helping a friend move, I noticed the vehicle was severely tilted forward causing the headlights to shine on the ground. I immediately stopped to adjust the height to prevent accidents. If you notice abnormal headlight alignment in the wild, an emergency solution is to use a flashlight to illuminate the hex socket screw inside the adjustment hole on top of the headlight for fine-tuning. After adjustment, remember to drive about 20 meters to check if the cutoff line is level. If the light beam is too scattered, refocus it.

As a seasoned driver who often drives at night, I find the CS55's headlight adjustment particularly practical. The dial with gears on the left side of the steering column is the height adjuster, which can be easily operated with just a twist of three fingers. I usually set the default position to gear 1, and adjust it to 0 on rainy days to reduce glare from wet road surfaces. After upgrading to LED lights, I felt the cut-off line wasn't stable enough, so I spent half an hour adjusting the gear behind the headlight with a wrench to calibrate it properly. Beginners must remember to adjust the lights on flat roads, as data obtained on inclined surfaces will be inaccurate.

Having driven the CS55 for five years, I’d like to share some insights on headlight adjustment. The up and down arrow knob on the left panel of the steering wheel is the height adjustment control—generally, turning it clockwise raises the beam, while counterclockwise lowers it. I remember once when the car was fully loaded climbing a hill, the front end lifted significantly, causing the headlights to point upward. Adjusting to level 3 immediately improved visibility. If the factory settings were accidentally altered, you can visit a 4S shop to recalibrate the headlights using a beam alignment tool. When manually adjusting the headlight screws, ensure the vehicle is level and aim for a sharp cutoff line on a white garage wall to avoid overlapping light projections from both headlights.
