Lift the engine hood and locate the adjustment knob at the rear of the headlight assembly. Use the appropriate tool for adjustment, but first determine whether to adjust left/right or up/down. Park the vehicle facing a wall at a distance of approximately 10 meters. Observe the height of the left and right lights, use tape or other markers for measurement, comparison, and adjustment. After adjusting the horizontal alignment of the headlights, find a reference point on the vehicle for comparison. Adjust the headlight height at a distance of about 10 meters, and adjust the horizontal position when closer. After completing the adjustments, observe from both inside and outside the vehicle. Simulate the opposing height for verification and fine-tune repeatedly until satisfactory.

As a long-time Highlander owner, I've found that the headlight height adjustment is typically located on the panel to the left of the steering wheel. There's a small rotary knob or button, often marked with a light symbol, that allows you to easily raise or lower the beam with a gentle turn or press. This feature proves particularly useful when vehicle loading changes - for instance, when the rear sinks under heavy trunk load, causing the lights to shine too high and potentially dazzle preceding drivers (simply lowering them improves safety). Conversely, raising the beams when unloaded provides better road illumination. If you can't find electric adjustment, your base model may require manual tuning: pop the hood, locate the adjustment bolts behind each headlight assembly, and carefully turn them with a screwdriver for calibration. I recommend periodic light checks, especially after rainy weather or rough-road driving, to ensure comfortable and safe nighttime visibility while preventing improper beam-related accidents. For unfamiliar owners, dealership technicians can handle this adjustment effortlessly.

From my frequent experience repairing Toyotas, the Highlander's headlight height adjustment is usually located in the button area at the lower right corner of the steering wheel in the cabin, and it's very simple to operate. You just turn that small roller wheel, and the lights will automatically move up and down to adapt to different road conditions. If the vehicle is heavily loaded at the rear causing the lights to shine too high and potentially dazzle oncoming drivers, lowering them can save you trouble; when driving on mountain roads or curves, raising them slightly improves visibility of distant areas. If there's no response, it might be due to a blown fuse or poor wiring contact—first check the dashboard warning lights. If you can't locate it, try consulting the owner's manual for a location diagram, or visit a shop for professional diagnostic tools. During maintenance, take the opportunity to adjust the height to avoid future issues, and make it a habit to test and adjust a few times before driving to ensure accuracy.

Having driven the Highlander for many years, the headlight height adjustment is quite easy to find—it's among the buttons on the left side of the steering wheel. Just twist the knob, and the lights gradually move up or down without much effort. This is especially useful when there's a significant change in load, like after loading up for a move, to prevent the lights from blinding others. In rainy weather, if the lights are too low and the road is hard to see, raising them can improve visibility. Keeping the height appropriate makes nighttime driving more secure, helping to avoid obstacles. If the knob is hard to find, it might be an older model requiring manual adjustment via a screw behind the headlight—turn off the car, open the engine bay, and use a tool to adjust. It's recommended for beginners to practice and familiarize themselves with the location; once you're used to it, it's a quick fix.
