How to Turn On/Off the Rear Wiper of Audi Q7?

[LoganLynn]

Audi Q7's rear window wiper control switch is located on the lever below the right side of the steering wheel. To turn it on, push the lever forward; to turn it off, pull it backward. There are two reasons why hatchbacks can be equipped with rear window wipers: 1. Shortcomings in hatchback aerodynamics: As the vehicle moves, part of the air flows with it, creating a low-pressure area at the rear due to insufficient air. When driving on dirty roads, dust or mud kicked up by the rear wheels accumulates in this low-pressure area at the rear, requiring a wiper to clean the rear windshield for safe driving. 2. Structural considerations: The rear door and glass of a hatchback are integrated, making it easier to install a wiper, and the wiper's pivot is not affected when the rear door is opened.
