Nissan Qashqai 2024 Owners Manual
10.15.1. Cleaning
If the windscreen or tailgate window is not clear after using the window washer or if a wiper blade chatters when running, wax or other material may be on the blade or windscreen.
Clean the outside of the windscreen or tailgate window with a washer solution or a mild detergent. The windscreen or tailgate window is clean if beads do not form when rinsing with clear water.
Clean the blade by wiping it with a cloth soaked in a washer solution or a mild detergent. Then rinse the blade with clear water. If the windscreen or tailgate window is still not clear after cleaning the blades and using the wiper, replace the blades.
After wiper blade replacement, return the wiper arm to its original position. Otherwise it may be damaged when the bonnet is opened.
Make sure the wiper blade contacts the glass. Otherwise, the arm may be damaged by wind pressure.
