3) Fluidic Washer Nozzle
This vehicle has the fluidic washer nozzle, which is designed to use fluid movement occurring in the
washer fluid spraying process.
When installing the washer nozzle, make sure that the mounting surface is clean and free of dirt or
debris, since the water may come into the engine compartment in accordance with a seamless
contact condition between the mounting surface of the nozzle and the curved surface of the engine
hood. *
The inside of the nozzle is designed in a fan shape to change the spray direction continuously based on
the time the fluid is sprayed. Refer to the figure below.
The spray direction is changed by means of the whirlwind and back flow generated while the washer
fluid is passing through the nozzle.Washer fluid inlet portSpray passage Counter-currentPassageWasher fluid outlet port

2. RAIN SENSING SYSTEM
In the rain sensing wiper operation system, the rain sensing unit only sends the information about the
amount of rain drops to the BCM, and it does not operate the wiper directly. The wiper and washer are
controlled by the BCM according to the driver's choice.
This sensor emits infrared rays through LED
and then detects the amount of rain drops
by receiving the rays reflected off the
sensing section (rain sensor mounting
section on the windshield) with photodiode.AUTO: Wiper operates automatically by rain

BCM
The rain sensor detects the amount of rain drops and sends the operating request signal to the BCM,
which drives the wiper directly. At this moment, the BCM also sends the information on whether the
wiper is in operation mode or whether the multifunction wiper switch is in AUTO position to the rain
sensor.
