3. 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. -

-
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.
Irregular operation (abrupt operation) ▶
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. -

1. OVERVIEW
The wiper & rain sensor system consists of the multifunction wiper switch, windshield wiper motor and
linkage, wiper arm and blade, rain sensor, wiper relay (LO/HI) and washer tank. The rain sensor does
not directly operate the rain sensing wiper and it sends only the data of the rainfall to the STICS. The
basic operation of the wiper and washer is controlled by the STICS according to the signal regarding the
multifunction switch operation modes (MIST, AUTO, LO/HI, washer, sensitivity adjustment).
Layout ▶
Windshield wiper motor & linkage
When the driver operates the switch so that
the wiper motor is activated, the linkage
converts the rotary motion to reciprocating
motion and transfers it to the wiper arm.
Windshield wiper arm & blade
It receives the power from the wiper linkage
and does a reciprocating motion (left to right).
Washer 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.Washer reservoir tank
Tank that supplies washer fluid to front
washer system.

Wiper (HI, LO) relays
Used 3-way relay consisting of 5-pinSTICS
It receives the signals regarding the rain

vehicle speed to control the wiper system
with the various functions.

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) 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

3) 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.
