The 2021 Teana does not have a manual switch for headlight height adjustment. Here are some precautions for car headlight maintenance: 1. Replacement: Car headlights must maintain good sealing, especially to prevent dirt and damage to the reflector coating. When replacing bulbs and diffuser glass, avoid touching the mirror surface with your fingers to prevent leaving sweat or oil marks, which can cause the reflector to lose its luster and reduce reflective efficiency. 2. Regular inspection: Regularly check and adjust the headlight beam to ensure the headlight's illumination distance meets requirements and that the high and low beams are aligned. The diffuser glass should be correctly installed as specified to prevent loosening or displacement and to maintain the vertical alignment of the prism.

I drive a 2021 Teana, and the headlight height adjustment knob is located just below the control lever on the left side of the steering wheel. There's a small rotary switch that you can gently turn to adjust the beam height. I find this feature very practical because when driving on mountain roads or uneven surfaces, if the lights are too bright, they might dazzle oncoming vehicles. Lowering them a bit is safer. Remember to adjust it on level ground and turn off the headlights before operating to avoid accidents. I often check the headlight height myself and make sure they're aimed at the right position when driving at night. In short, don't underestimate this function—it can prevent accidents at critical moments. New car owners might overlook it, so taking some time to familiarize yourself with the operation is worthwhile. Car maintenance starts with these details.

As an experienced driver, I find the headlight height adjustment knob on the 2021 Teana is very well positioned. It's located on the left side of the steering wheel near the dashboard, featuring a graduated dial. Rotating it adjusts the beam height - higher numbers lower the lights to avoid dazzling pedestrians. I recommend new drivers or those switching cars to familiarize themselves with this feature first. Adjust it in a quiet place, never while driving to avoid distraction. I also follow the vehicle manual's advice to regularly check if the lights are balanced, preventing uneven illumination that could affect visibility. Small adjustments contribute to safe driving, and making it a habit ensures more confidence when driving at night.

I drive this car daily, and adjusting the headlight knob is as simple as a twist near the steering wheel. Before operating, make sure the car is parked on level ground, then gently rotate the adjustment knob to test the height effect. As I get older, I need more lighting assistance for visibility, so I slightly raise the lights to cover longer distances for clearer vision. Remember, safety first—if the lights are unstable, don’t force driving; it’s best to take the car back to the shop to check the wiring or other potential issues. Though a small feature, it’s practical. Mastering it in just a few minutes can enhance the overall driving experience, making night drives more reassuring.
