rising or setting of the sun intermittently strikes the windshield, or if bugs etc. are present on the windshield.
●If the wiper is turned to AUTO position while the engine switch is
in IGNITION ON mode , the wipers will operate once to show that AUTO mode is activated.
●If the temperature of the raindrop sensor is 85°C (185°F) or higher, or -30°C (-
22°F) or lower, automatic operation may not occur. In this case, operate the wipers in any mode other than AUTO.
■If no windshield washer fluid sprays
