3) Fluidic Washer Nozzle
Fluidic Washer Nozzle is applied to the front washer spray system in this vehicle. The inside of
nozzle is designed to utilize the fluidic movement.
This is a shape of the inside of nozzle. It is designed to change the spraying direction
continuously according to the spraying time (fan-shape). The figure below shows the changes of
spraying direction according to the spraying time.
It is designed to be changed spraying direction using the whirlwind and backflow generated in
nozzle.Washer fluid inletSpray passage Counter-currentPassageWasher fluid outlet

Auto washer switch
Pressing the switch makes washer fluid to be
sprayed for 2 sec. with four wiping, and washer
fluid to be sprayed for 1.5 sec. with three
wiping, with no delay of time
Front nozzle
Installed on both sides of the cowl grille
assembly (one on each side). Sprays
washer fluid in fan-shape to cover the
windshield area as much as possible.

1) Wiper and Washer Fluid Switch Operation
The wiper operates for 1 cycle when
pushing up the lever. The lever will return
to the "OFF" position when released.Front Automatic Wiping Speed

Front Auto Washer Switch (AFW)
When the front wiper switch is off
and this switch is pressed,
washer fluid will be sprayed and
the wiper will automatically
operate 4 times. Then, the fluid
will be sprayed again and the
wiper will automatically operate 3
times.

2) STICS Control Logic Related to Wiper and Washer
Wiper MIST and Front Washer Coupled Wiper ▶
The wiper relay is turned on 0.3 seconds after turning "ON" the washer switch for 0.1 ~
0.59 seconds with the ignition key "ON", and it is turned off when the parking terminal is
turned off. 1.
The wiper relay is turned on at 0.3 seconds after from the time when the washer switch is
turned on for more than 0.6 seconds with the ignition switch "ON". The wiper relay gets on
3 times immediately after turning off the washer switch. 2.

07-8
When the washer switch is turned on for more than 0.6 seconds during the wiper operation
by INT switch, the operation in step (2) is performed.
When it is turned on for a certain period of time (0.1 to 0.59 seconds), the operation in
step (1) is performed. 3.

Multifunction Wiper Switch:
AUTO and Sensitivity Control
1. OVERVIEW
The rain sensing wiper unit system doesn't control the wiper directly. The rain sensing unit
detects the amount of rain drops and sends the operating signal to STICS, and STICS drives the
wiper directly.
Rain Sensing Unit
(AUTO Light Sensor Integrated Type)
A sensor that emits infrared rays through LED
and then detects the amount of rain drops by
receiving reflected rays against sensing
section (rain sensor mounting section on the
windshield) with photodiode. The auto light
sensor is Integrated into the rain sensor (refer
to the below picture).AUTO: Wiper operates automatically by
rain sensor
FAST SLOW: Auto delay/auto speed
control. A position that can control
sensitivity against rains on the windshield
and transmits wiping demand signal
accordingly.
Emitter lens
The LED which is located at
bottom emits the infrared rays
and the lens guides the infrared
rays to target point.

STICS Engine Compartment Fuse Box
STICS ▶
The rain sensing unit detects the amount of rain drops and sends the operating signal to STICS,
and STICS drives the wiper directly. At this moment, STICS determines the wiper operation mode
(washer, MIST, AUTO), then sends the information to the rain sensor.
Auto Light Sensor and Rain Sensor Coupled Control ▶
Rain detected headlamp: If it rains heavy which requires the highest INT speed (almost
LOW), the headlamps are turned on automatically. -
Night detected wiping: When the auto light control turns on the headlamps and the rain
sensor detects the rain, the wiper sensitivity is automatically increased by one level in
comparison with daytime.
(i.e. the AUTO wiper switch is at the 3rd level, but the wiper operates at the 4th level.) -Wiper relay (HI)

1) Power-up Reminder Wiper Function
When turning off and on the auto INT switch, the system drives the wiper motor through
LOW relay regardless of communication with rain sensor. 1.
When turning the INT-AUTO switch from the "OFF" to "ON" position with the ignition
switch in the "ON" mode, the LOW relay operates to drive the wiper motor for 1 cycle,
regardless of the rain sensor communication.
After that, when turning the INT-AUTO switch from the "OFF" to "ON" position, the LO
W
relay operates to drive the wiper motor for 1 cycle only if data from the rain sensor
indicates rain drops. 2.
2. FUNCTIONS OF RAIN SENSING WIPER

2) Washer Coupled Wiper in Rain Sensing Mode
The washer coupled wiper is operated when receiving the washer switch input with the
ignition switch "ON" and the auto INT switch "ON" in rain sensing mode. At this moment,
the communication with the rain sensor is overridden. However, a washer input is
overridden if there is an output for continuous operation.
The operation data is sent to the rain sensor even during the washer coupled wiper's
operation. 1.
