Rain Sensor Installation Note

WARNING: This page is about a different car, the 2018 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

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 malfunction in the rain detection function and stop 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 windshield with your fingers
- Verify that there is no air bubble after installing the rain sensor

Wipe off any oil or dirt from the rain sensor lens and the windshield using a clean rag.
