Recognition Sensor - G397- frame before installing. Re‐
move any traces of the connecting pad still remaining on
the windshield.

sor - G397- must not be contaminated or damaged when
installing. Always replace a sensor that has a damaged
connecting pad. Refer to

Even if the sensor is installed correctly, small air bubbles can form

face must be free-of-bubbles after approximately 10 minutes. If
the contact surface is not free of bubbles after 10 minutes, the
Rain/Light Recognition Sensor - G397- must be removed and in‐
stalled again. Air bubbles between the windshield and the con‐
