The method to adjust the headlights of the Avalon is as follows: 1. Park the car approximately 10 meters away from a wall; 2. Measure the height from the ground to the center of the headlights and the distance between the two headlights; 3. Place a horizontal masking tape on the wall at a point 0.1 meters lower than the headlight height and centered; 4. Adjust the vertical adjustment screw until the headlight beam is centered on the tape on the wall. Taking the Avalon 2021 2.5L Luxury Edition as an example: It is a mid-size 4-door 5-seater sedan under FAW , equipped with an 8-speed automatic transmission, a fuel tank capacity of 60L, and front-wheel drive.

Adjusting the headlights on the Avalon is actually quite simple. I've done it myself several times in the garage. There's a headlight height adjustment wheel under the steering wheel on the driver's side—it's the knob with up and down arrows. You can operate it while sitting in the car; rolling it up raises the lights, and rolling it down lowers them. Make sure to do this at night against a wall, keeping the car about 5 meters away so you can clearly see the changes in the light cutoff line. I usually start by setting it to the middle position and test-driving it. If it's not bright enough, I raise it one more notch, but don't set it too high to avoid blinding oncoming drivers. When the trunk is loaded with heavy items, the rear of the car sinks, which affects the headlight height. In this case, you'll need to fine-tune the wheel again. Models with automatic headlights don't require manual height adjustment—just turn the lever to AUTO mode. If the automatic setting isn't ideal, you can still manually adjust the wheel.

Adjusting the headlights isn't actually that complicated. I had my new Avalon adjusted right after purchase. There are two main control points: a physical scroll wheel below the steering wheel on the left side for manual height adjustment (clearly divided into 0-5 levels), and a button on top of the turn signal stalk for auto-sensing mode. For best results, make adjustments at night in an underground parking garage - observing the light cutoff line against a wall makes changes very noticeable. Some worry about needing special tools for professional adjustment, but that's completely unnecessary. Just remember not to adjust immediately after starting the car; wait until the engine stabilizes. If it seems troublesome, the easiest solution is to have adjust it during routine maintenance at the dealership - they can do it in under a minute. In auto mode, the headlight height actually makes micro-adjustments based on vehicle speed, so there's no need to worry about insufficient illumination at highway speeds.

Adjusting the headlights is really effortless, and my Avalon handles it smoothly. When opening the car door, first locate the round wheel under the left instrument panel—the one with up and down arrows is the light adjustment knob. The manual settings range from 0 to 5: level 0 is the lowest, suitable for city driving; level 3 is moderate for highways; level 5 is the highest but should not be used frequently. Make sure the car is parked on level ground when adjusting, otherwise the headlights may become unbalanced. I prefer adjusting against a wall at night, aligning the beam cutoff line roughly with the headlight height. For models with automatic headlights, simply turn the stalk to the AUTO position, and the system will handle the rest. A small tip: if the rear seats have three passengers or the trunk is fully loaded, the front of the car may rise slightly—in this case, lower the headlight level appropriately to prevent glare. After adjusting, it's best to test the effect by driving at night.

I've researched headlight adjustment multiple times, mainly divided into manual and automatic methods. For manual adjustment, use the physical scroll wheel on the lower left side of the steering wheel - turn clockwise to raise the beam height, counterclockwise to lower it. Before adjusting, park the car on level ground with the front about 7 meters from a wall. You'll see the light cutoff line move up/down on the wall as you turn the wheel; adjust until it shines just below other vehicles' rearview mirrors. Automatic mode setup is simpler - just turn the light stalk to the position marked with 'A'. Note that some premium models allow adjusting auto headlight sensitivity via the center display; I usually set mine to medium response speed. Regular light checks are crucial - especially before long trips I always verify the beam height. Driving on uneven roads can misalign the lights, requiring recalibration.

I specifically went to the 4S dealership to learn headlight adjustment techniques. The core of manual adjustment is the physical dial mechanism, which is positioned above the driver's left knee in the Asian Dragon model, allowing for blind operation while driving. When adjusting, set the height based on your driving view: choose level 2 for average-height drivers, level 3 for taller individuals, and lower it to level 1 when carrying heavy loads. Automatic headlights are set via the lever—simply turn to the AUTO position to activate full automation. The system automatically adjusts the beam pattern based on speed: wider spread at low speeds and narrower focus at high speeds. A common misconception is that bulbs don't require adjustment, but proper beam focus is crucial for any bulb type. It's best to check headlight alignment before annual inspections, as incorrect height can compromise safety. Set the standard height when you first get the car; unless you replace the springs, readjustment is rarely needed afterward.
