It may not operate properly when sunlight from the rising or setting of the sun intermittently strikes the windshield, or if bugs etc. are present on the windshield. l If the wiper switch is turned to "AUTO" position while the "POWER" switch is in ON mode, the wiper operate once to show that auto mode is activated. l If the temperature of the raindrop sensor is 194°F (90°C) or higher, or 5°F (-15°C) or lower, automatic operation may not occur. In this case, operate the wipers in any mode other than "AUTO". 223
