1. WIPER CONTROL
2. CAUTIONS ON RAIN SENSOR
When the wiper switch is in the AUTO position, the wiper will operate for 1 cycle if the initial engine
start is made. This may cause the wiper blades to wear prematurely. Therefore, other than rainy
days, set the switch to the OFF position. Especially during the winter time, check if the wiper blades
are not frozen to the windshield.
Operating the wiper with the blades frozen can damage the wiper motor.
If you operate the wipers when the windshield is dry without spraying washer fluid, the windshield
can be scratched and the wiper blades can wear prematurely. Use the wiper with the washer fluid
when the windshield is dry.
When it does not rain, turn the wiper switch to the OFF position.
Turn the wiper switch to the OFF position before any car wash to avoid unwanted operation of the
wipers. -

Check if the sensor is off the position.
Check if the rain sensor cover is securely installed.
Check if the customer is familiar to how to control the wiper sensitivity.
Check if the wiper sensitivity control is set to the FAST side (step 5).
Check the wiper blade for wear.
If the wiper blade cannot wipe the glass uniformly and clearly, it may cause the rain sensor to
work irregularly. Therefore, in this case, replace the wiper blade with a new one. -

- Irregular operation (abrupt operation) ▶ When cleaning the windshield over the sensor with damp clothes, the wiper may operate suddenly. It
could cause serious injury. Make sure to place the wiper switch to the OFF position and ignition switch
OFF when not in use.

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. Operating part for rear

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.
Rain sensing unitMultifunction wiper switch
AUTO and sensitivity control
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.
