The engine switch is in IGNITION ON mode.
■Raindrop sensor (vehicles with rain-sensing windshield wipers)
●If the wiper switch is turned to the “AUT O” position while the engine switch is in
IGNITION ON mode, the wipers will operate once to show that “AUTO” mode is acti-
vated.
●When the sensor sensitivity ring is turned toward high wh ile in “AUTO” mode, the wip-
ers will operate once to indicate that the sensor sensitivity is enhanced.

■Effects of vehicle speed on wiper operation (vehicles with rain-sensing windshield wip-
ers)
With the settings other than “AUTO” also, the time until drip prevention wiper sweep
occurs is changed depending on vehicle speed.
With the low speed wiper oper
ation selected, wiper operation will be switched from low
speed to intermittent wiper operation only when the vehicle is stationary. (However,
when the sensor sensitiv ity is adjusted to the highest leve l, the mode cannot be switched.)
■If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the windshield
washer fluid reservoir.

shield is subject to vibration in “AUTO” mode . Take care that your fingers etc. anything
else does not become caught in the windshield wipers.
