■Raindrop sensor (vehicles with rain-sensing windshield wipers)
●If the wiper switch is turned to AUTO position while the “START STOP ENGINE”
<“POWER”> switch is in IGNITION ON mode, the wipers will operate once
to show that AUTO mode is activated.
●When the sensor sensitivity ring is turned toward high while in AUTO mode, the
wipers will operate once to indicate that the sensor sensitivity is enhanced.
●If the temperature of the raindrop sensor is 185°F (85°C) or higher, or -22°F
(-30°C) or lower, automatic operation may not occur. In this case, operate the
wipers in any mode other than AUTO mode.
■If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the wind-
shield washer fluid reservoir.
●The raindrop sensor judges the amount of
raindrops.
An optical sensor is adopted. 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.
CAUTION
■Caution regarding the use of windshield wipers in AUTO mode (vehicles with
rain-sensing windshield wipers)
The windshield wipers may operate unexpect edly if the sensor is touched or the
windshield is subject to vibration in AUTO mode. Take care that your fingers or
anything else do not become ca ught 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.
