How to Turn on the Mercedes-Benz E-Class Wiper?

[StMax]

The wiper switch of the Mercedes-Benz E-Class is located on the left rear side of the steering wheel. Setting it to AUTO activates the automatic rain-sensing system. Pressing it down once adjusts the speed, though AUTO is generally sufficient. The wiper switch is combined with the turn signal switch. Pressing inward from the outer part of the combo switch head activates the windshield washer. Precautions for using the wipers: 1. Maintain cleanliness: Dirty wiper blades can leave streaks on the windshield. Use a towel dampened with alcohol to wipe along the edge of the wiper blade to remove accumulated dirt, debris, and dead leaves. Clean the wiper blades monthly to keep them in good condition. 2. Check the rubber: If the windshield produces a screeching sound, the wiper blade rubber may have hardened, worn out, or cracked. If the wear is not severe, the owner can sand the uneven surfaces with sandpaper. 3. Avoid sun exposure: Park the car in a ventilated and shaded area whenever possible. Especially in hot weather, many people park their cars outdoors under direct sunlight. High temperatures are the nemesis of rubber materials, which accelerates the aging of wiper blades. 4. Refill fluid: Some owners prefer using plain water to refill, which may damage the glass and wipers. To prolong the lifespan of the components, always use proper windshield washer fluid. Ensure timely refilling during daily driving. 5. Remove frost: In cold northern regions with heavy snowfall, the car's wipers can easily freeze. In such cases, manually clear the frost from the glass surface. Forcibly activating the wipers can bend the mechanical structure, damage the wiper blades, scratch the glass, or even burn out the wiper motor in severe cases.
