Rain Sensor Installation Note

CAUTION:
  • If the rate at which the rain sensor reflects or transmits infrared light between the rain sensor and the windshield, or through the protective sheet, is changed, the rain sensor will determine that there is a problem in the rain detection function and stop the auto wiper system control. Be careful of the following when installing the rain sensor:
    • Do not reuse the rain sensor protective sheet.
    • Do not touch the rain sensor lens, rain sensor protective sheet, and sensor installation area on the windshield with your fingers.
    • Verify that there are no air bubbles after installing the rain sensor.
  1. Wipe off any oil or dirt from the rain sensor lens and the windshield using a clean cloth.
