What is the appropriate headlight height adjustment level?

[RachelFitz]

Generally, the headlight height should be adjusted to position 0. The adjustment knob is usually located on the left side of the dashboard, near the light control switch. The knob is marked with numbers from 0 to 3, where higher numbers indicate lower beam height. Headlight height adjustment guide: Position 0 is the default horizontal setting, suitable when front seats are occupied and the trunk is empty. Positions 1 to 3 are appropriate when the vehicle is fully loaded with passengers and cargo. Since a vehicle's height isn't fixed and changes with suspension travel when loaded or unloaded, proper headlight adjustment is necessary to maintain driving safety, especially at night, by compensating for changes in vehicle level height.
