Is Genuine Mercedes Windshield Washer Fluid Mandatory?

[Victor]

Mercedes windshield washer fluid does not necessarily have to be genuine. Engage the car's parking brake: Activate the vehicle's parking brake to prevent the car from rolling while adding washer fluid. Open the car's hood: Pull the front hood release lever located at the lower left corner of the car to ensure it can be opened. Locate the windshield washer fluid reservoir: After opening the hood, find the windshield washer fluid filler port. Add windshield washer fluid: Pour an appropriate amount of washer fluid, paying attention to the level indicator. Do not overfill - stop when reaching the marked line. During refilling, be particularly careful not to exceed maximum capacity. If some foam appears at the reservoir opening, this is normal and won't affect the washer fluid's functionality.
