LS600hL_U(OM50E41U)
■Raindrop sensor
●If the wiper is turned to “AUTO” mode while the power switch is in ON mode, the
wipers will operate once to show that “AUTO” mode is activated.
●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” 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.
■Outside rear view mirror defogger activation linked to windshield wiper operation
The outside rear view mirror defoggers automatically turn on when you operate the
windshield wipers.
The outside rear view mirror defoggers automatically turn off approximately 15 min-
utes after the wipers stop.
For details about the outside rear view mirror defoggers: P. 3 5 8
●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
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.
