What is the appropriate setting for Corolla headlights from 0 to 5?

Corolla headlight height adjustment should be determined based on the vehicle's load conditions. Here's how to adjust Corolla headlights: 1. When the car is driving with minimal load or on flat roads, with only the driver or both driver and front passenger present, select 0; 2. When the car has a driver and front passenger with no luggage in the trunk, set the headlight knob to 0; 3. When the car is fully loaded with passengers but no luggage in the trunk, set the headlight knob to 2; 4. When the car is fully loaded with passengers and luggage in the trunk, set the headlight knob to 3. Taking the 2021 Corolla as an example, its body dimensions are: length 4635mm, width 1780mm, height 1455mm, wheelbase 2700mm, fuel tank capacity 43L, and curb weight 1410kg.
I've just dealt with a similar issue. The Corolla's headlight height adjustment knob has settings from 0 to 5. Setting 0 is the lowest beam position, suitable for unloaded vehicles, while 5 is the highest position for fully loaded conditions. As someone who frequently drives long distances, I recommend setting it to 0 or 1 for daily driving—it ensures clear visibility without blinding oncoming traffic. If carrying passengers or luggage, the added weight causes the rear to sink and the beams to rise, making settings 2 or 3 more appropriate. The adjustment method is simple: at night, find a flat surface, turn on the lights, and check if the beam pattern falls within the proper range on the ground. Avoid setting it too high, as it’s both dangerous and inconsiderate. Regularly checking your headlights ensures safer driving.
When I first encountered the Corolla, I also had questions about the headlight settings. In the 0 to 5 dial, the higher the number, the more upward the light beam points. Typically, when the vehicle is empty, selecting 0 is the safest option; when fully loaded with passengers or cargo, adjust it down to 3 or 4. The reason is simple: if the lights are too high, they can dazzle other drivers, creating a safety hazard. I recommend that beginners test it themselves: park in front of a wall, turn on the lights, and adjust to see which position gives the most moderate light spot. Remember, 0-1 is optimal for light loads, while 3-4 is reasonable for heavy loads. Don’t overlook this setting—it affects both comfort and safety during night driving. It’s easy to figure out with a little time.
After driving the Corolla for a long time, I've summarized the headlight level adjustment method. Position 0 is the lowest setting for an empty car, while position 5 is the highest for heavy loads. Most of the time, setting it to 1 provides the best balance: not dazzling others while maintaining good visibility. When carrying weight, reduce it to 2 or 3. Setting it too high can be risky as other drivers might flash their lights in protest. Experience tells me that proper adjustment helps avoid unnecessary troubles.
