Where is the windshield washer fluid filler port on the Mercedes-Benz C260?

The windshield washer fluid reservoir of the Mercedes-Benz C260 is located at the rear side of the engine hood pressure strut, with a washer symbol on the cap. The procedure for adding windshield washer fluid to the Mercedes-Benz C260 is as follows: 1. Use the windshield wiper switch knob to spray out the existing washer fluid; 2. When the wiper nozzles stop spraying, open the washer fluid filler cap and add a small amount of newly prepared washer fluid; 3. Activate the wiper switch again to clear out any remaining old washer fluid; 4. When no more fluid sprays out during the second activation, add approximately 4 liters of washer fluid solution, then securely close the cap to complete the filling process.
