Let me explain to you right away. To activate the automatic high beams on your Mercedes Classe A W177, all you have to do is set the light control correctly.

First of all, make sure that the headlight lever, located to the left of the steering wheel, is set to the automatic lighting mode (the headlight icon with the sensor). Then, the ambient light detection system comes into play: if your car detects a sudden change in light (for example, when entering a tunnel or at night), the headlights will automatically switch to high beams.

Don't worry, the system is intelligent and, when it recognizes vehicles coming from the opposite direction or in front of you, it will lower them automatically to avoid dazzling others. If you can't set them yourself, contact an expert.
