The switch for the automatic rain sensor on a is located on the lever below the steering wheel, with clear markings. Simply move it up and down to operate. It's important to note that because Mercedes-Benz vehicles use a gear shift design, the traditional wiper lever has been replaced by the gear shift lever. As a result, the wiper lever is positioned on the turn signal lever. The outermost button on the turn signal lever is for the windshield washer function—pressing it will spray washer fluid. More details are as follows: 1. Principle: The automatic wiper system is an automated car feature. When it rains, raindrops fall on the windshield, and the vehicle's sensors detect the presence of water. Based on the sensed data, the system automatically adjusts the wipers for cleaning and can also regulate the wiper speed according to the intensity of the rain. When there is no rain, the wipers will stop automatically. 2. Regular Cleaning: When washing your car, it's also essential to clean the wiper blades, especially any residual sand particles. Neglecting regular cleaning can lead to accelerated wear of the wipers.
