1. WIPER AND WASHER SYSTEM

1) AUTO Washer Coupled Wiper Function

If you press the AUTO washer switch briefly with the ignition key ON and INT-AUTO switch "OFF", the 

washer motor is operated for about 2 seconds to spray washer fluid once after the switch is turned ON 

and the wiper relay is turned ON for 4 cycles. After that, the washer motor is operated for about 2 

seconds to spray the washer fluid again and the relay is turned ON for 3 cycles and then the relay is 

turned OFF.

2) Rear Washer Fluid Supply System

The front washer fluid reservoir supplies the rear washer fluid without additional washer fluid reservoir.

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.

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 

sensor

FAST <-------> SLOW: 

Auto delay/auto speed control. 

A position that can control the sensitivity for 

the amount of rains on the windshield and 

transmit the wiping request signal 

accordingly.

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.
