If the wiper blades leave streaks across the windshield, try cleaning them first with a paper towel or soft cloth and wiper fluid. If the wiper blade rubber has deteriorated, you should change the wiper blades.

1. Set the power mode to VEHICLE OFF (LOCK).
2. Lift the driver side wiper arm first, then the passenger side.
3. Press up on and hold the tab, then slide the holder off the wiper arm.
   
4. Pull the end of the wiper blade in the direction of the arrow in the image until it unfastens from the holder's end cap. Pull the wiper blade to the opposite direction to slide it out from its holder.
