[McEdward]

The button for removing rainwater from the rearview mirror is located on the air conditioning control panel and is the same button used for rear window defogging. Relevant information about the windshield wiper is as follows: 1. Introduction: The wiper, also known as a windscreen wiper or windshield wiper, is a device used to wipe away raindrops and dust attached to the vehicle's windshield, improving the driver's visibility and enhancing driving safety. 2. Usage: On rainy days, when raindrops fall on the windshield, the view ahead quickly becomes obstructed, making vehicles, pedestrians, and scenery appear blurry. At this time, turning on the wiper will restore a clear view ahead.
