The wiper relay (LO) is turned on and the wiper motor runs one cycle when the wiper sensitivity is
changed to 2 from 3 during receiving the malfunction signal (1) from the rain sensor. However, the
wiper motor can be operated only when the rain sensor detects the "Rain Detected" signal. 1)
If the volume sensitivity is changed more than 2 stages within 2 seconds, the wiper motor runs
only one cycle. ▶ Defective rain sensor

The wiper relay (LO) is turned on and the wiper motor runs one cycle when the wiper sensitivity is
changed to 2 from 1 during receiving the malfunction signal (3) from the rain sensor (while the
ignition key is in “ON” position and the wiper switch is in “AUTO” position). Also, the wiper
relay (LO) is turned on and the wiper motor runs one cycle when the wiper sensitivity is changed to
2 from 1 during receiving the ground fixed or IGN fixed signal from the rain sensor. 3)
The wiper relay (LO) is turned on and the wiper motor runs one cycle when the wiper sensitivity is
changed to 3 from 4 during receiving the malfunction signal (2) from the rain sensor (while the
ignition key is in “ON” position and the wiper switch is in “AUTO” position). 2)

4. FUNCTIONS OF RAIN SENSOR
1) Windshield Glass and Coupler Attachment
Check the outer windshield surface of sensing area for wear, damage and scratch. The sensor is able
to compensate the wear up to a specific level. Check the coupler attached surface of windshield for
porosity. If the porosity exists, the sensor cannot function properly.
2) Recognition of AUTO Mode
3) Instant Wipe Function
When the variable resistance knob on the multifunction wiper switch is turned by each 1 stage from
low sensitivity (S mark) to high sensitivity (F mark), the wiper operates one cycle.
And, the wiper also operates during raining up to 5 minutes after rain stops.When the engine is started with the wiper switch “AUTO” position, the wiper operates one
cycle to remind a driver that the wiper switch is in “AUTO” position.
When the wi
per switch is turned to “AUTO” from OFF, the wiper operates one cycle. It always
operates one cycle for the initial operation, however, the wiper does not operate afterwards to
prevent the wiper blade wear if not raining when turning the wiper switch to “AUTO” from
“OFF”. However, the wiper operates up to 5 minutes after rain stops.
If this function does not occur, check No. 2 terminal on the rain sensor. If any defective cannot be
found, check the wiper relay (LOW) for defective. 1.

3.If the installed wiper brushes are out of specification (size and length), the rain sensing area
cannot be fully wiped. In this case, the rain sensor’s sensitivity could be decreased and
the wipers are not properly operated. - The followings are the detailed description of the functions and operations of the rain sensing wiper
control.
As described, the STICS recognizes the wiper switch “AUTO” position. If there are not any
problem, go to diagnosis mode in STICS and check the terminal that receives signal from wiper
and communication lines between rain sensor unit and STICS. -
When the variable resistance knob is rotated by 4 stage from 0 stage without stopping, the wiper
operates one cycle. The wiper operates one cycle when changing the wiping stage (0 →
1, 1 → 2, 2 → 3). -

2. CAUTIONS
The parking aid system is just a supplemental device to help your parking.
Always keep the safety precautions.
Do not press or shock the sensors by hitting or using a high-pressure water gun while washing,
since it may damage the sensors.
If the system is in normal operating condition, a short beep sounds when the shift lever is moved
into "R" position with the ignition key "ON".
If the system is defective, the warning buzzer sounds for 3 seconds when moving the gear shift
lever to “R” position with the ignition ON. Be careful not to confuse this and the parking aid
alarm (in 50 cm). 1.

- Note that the display does not show everything in the rear area. Always check
nobody, especially animals and children, is behind the vehicle when parking or
reversing.
- If you can not properly check the vehicle behind, get out of the vehicle and then
visually check it.
The parking aid system will not work or improperly work under following cases: ▶
1) Certain obstacles that sensors can not detect
Thin and narrow objects, such as wires, ropes, chains
Cotton, sponge, clothes, snow; that absorb ultrasonic waves
Obstacles lower than the bumper (ex. drain ditch or mud puddle) -
-
-
2) Not defective but improperly working
When the sensing portion is frozen (operates normally after thawed)
When the sensing portion is covered by rain, water drops, snow or mud (operates normally after
cleaned)
When receiving other ultrasonic signals (metal sound or air braking noises from heavy commercial
vehicles)
When a high-power radio is turned on -
-
-
-
3) Narrowed sensing area
When the sensing portion is partially covered by snow or mud (operates normally after cleaned)
Surrounding temperature of sensor is too high (approx. over 80°C) or too low
(approx. below -30°C) -
-
4) Not defective but may cause malfunction
When driving on the rough roads, gravel road, hill and grass
When the bumper height is changed due to heavy load
When the sensing portion is frozen
When the sensing portion is covered by rain, water drops, snow or mud
When receiving other ultrasonic signals (metal sound or air braking noises from heavy commercial
vehicles)
When a high-power radio is turned on
When some accessories are attached in detecting ranges -

4) ARP (Active Roll-Over Protection)
The ARP (Active Roll-over Protection) system is a safety assistant device that minimizes, by controlling
brakes and the engine, the physical tendency of the vehicle rollover during sharp lane changes or U-
turns. For the system, software is added to the existing ESP system and no additional device or switch
is needed. One must note that the ARP system, just as general assistant devices including the ABS, is
only a safety assistant device using the ESP system and its function is useless when the situation
overcomes the physical power. Following picture shows how the ARP compensates the vehicle
position by varying each wheel's braking power to overcome the physical tendency of the vehicle
rollover during sharp turns.
The vehicle driving condition is controlled by the internally programmed logic according to the input
signals from wheel speed sensor, steering angle sensor and lateral sensor.

Seat Warmer Switches
3) To Activate Driver & Front Passenger Seat Warmer
Operating condition ▶
Turn the ignition key to the "ON" position and start the engine.
If the cranking signal is inputted, the seat warmer stops working during cranking.
Operation description ▶
When pressing the seat warmer switch for the driver and/or front passenger seat with IGN ON, the
seat warmer operates. Press the switch again to stop the seat warmer.
Operation procedures ▶
When pressing the seat warmer switch for the driver and/or front passenger seat, the seat warmer
relay in the ICM box is activated to supply power to the seat warmer.
