How to Deal with Mercedes-Benz Headlight Flashing and 'Stop Operation' Warning?

[VonLeilani]

1. During daytime or nighttime engine startup, listen for any abnormal noises when the lights automatically adjust, and observe whether the light beams on the ground are shaking. After the shaking stops, check if the 'Intelligent Light System Stop Operation' warning appears. 2. Open the engine compartment. There are two white adjustment screws above each headlight (left and right) for adjusting height and width. Use a long Phillips screwdriver for adjustments. 3. Avoid excessive adjustments. After each adjustment, turn off and restart the engine, then observe the adjustment effect after the light self-check. 4. If abnormal noise or shaking occurs, identify which side is affected and adjust it by referring to the opposite side. Note the automatic adjustment trajectory—if noise occurs when turning right, adjust left; if noise occurs when turning up, adjust down. 5. After completing adjustments, test with high and low beams during left and right U-turns. If the 'Intelligent Light System Stop Operation' warning appears, the beam pattern of the problematic headlight will change. Note the steering direction that triggers the warning, then adjust the affected headlight in the opposite direction after stopping.
