Raindrop sensor (vehicles with rain-sensing windshield wipers)
■
The raindrop sensor judges the amount of
●
raindrops.
An optical sensor is adopted. It may not oper-
ate properly when sunlight from the rising or
setting of the sun intermittently strikes the
windshield, or if bugs etc. are present on the
windshield.
If AUTO mode is selected while the power switch is in ON mode, the wipers will oper-
●
ate 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 wip-
ers in any mode other than AUTO mode.
When the windshield wipers are in temporary operation
■
AUTO mode cannot be activated even if
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.
WARNING
Caution regarding the use of windshield wipers in AUTO mode
■
The windshield wipers may operate unexpectedly if the sensor is touched or the wind-
shield is subject to vibration in AUTO mode. Take care that your fingers or anything
else do not become caught in the windshield wipers.
Caution regarding the use of washer fluid
■
When it is cold, do not use the washer fluid until the windshield becomes warm. The
fluid may freeze on the windshield and cause low visibility. This may lead to an accident,
resulting in death or serious injury.
