2464-3. Operating the lights and wipers
GS350/250_EE (OM30C36E)
Raindrop sensor (vehicles with rain-sensing windshield wipers)
If the wiper is turned to AUTO mode while the engine switch is in IGNI-
TION 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 mode.
When the windshield wipers are in temporary operation
AUTO mode cannot be activated even if is pressed.
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.
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 intermit-
tently 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 unexpectedly 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 caught in the windshield wip-
ers.
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.

When working on the engine compartment
Keep hands, clothing and tools away from the moving fan and engine
drive belt.
Be careful not to touch the engine, radiator, exhaust manifold, etc. right
