2. FUNCTIONS OF RK STICS
1) Wiper Control
(1) Wiper MIST and Washer Coupled Wiper
The wiper relay is turned on 0.3 seconds (T1) after turning “ON” the washer switch for 0.2 ~
0.59 seconds (T2) with the ignition key “ON”, and it is turned off when the parking terminal
is turned off. 1.
The wiper relay is turned on 0.3 seconds (T1) after turning “ON” the washer switch over 0.6
seconds (T2) with the ignition key “ON”, and it is turned on three times immediately after
turning off the washer switch. 2.

The wiper system continuously outputs the parking signal of current sensitivity when the parking
terminal is grounded (while the ignition key is in “ON” position and the wiper switch is in
“AUTO” position). 1)
※ The wiper motor runs only when the rain sensor requires.
When the parking terminal is fixed to IGN (HIGH), the wiper system outputs the operating signal of
current sensitivity for 2 seconds, then continuously outputs the parking signal of current sensitivity. 2)
※ The wiper motor runs only when the rain sensor requires.

▶ Speed Sensitive INT (Intermittent) Wiper
For STICS without rain sensor, perform the following operation:
1. Controls the wiper intermittent operation by the values from vehicle speed and volume.
Calculates and converts the Intermittent interval automatically by using the vehicle speed and INT
VOLUME when the ignition switch is in “ON” position and the INT switch is in “ON”
position (the engine is running).
The wipers are operated in vehicle speed sensitive mode when turning the INT switch to
“ON” position with the engine running or starting the engine with the INT switch positioned
“ON”.
Intermittent interval (at 0 km/h): 3 ± 0.5 ~ 19 ± 2 seconds -
-
-
2. Vehicle speed calculation
[Input the vehicle speed]
It is calculated by the numbers of input pulses for one second.
1 [pulses/sec] = 60 [km/h] x 60 [sec] / 637 pulses = 1.41 [km/h]
3. VOLUME calculation
Calculates the INT VOLUME with 5 grades as shown in the table in next page. -
4. Pause time calculation
Pause time: the duration that wipers are stopped at parking position
Elapsed time: the duration after the wiper motor started to operate from parking position
The pause time is calculated by the vehicle speed and VOLUME value as shown in the table in
next page. -
-
-
If the pause time is below 1.0 second, the wipers operate without pause.
If the pause time is over 1.5 seconds, the wipers operate intermittently. ·

The wiper relay continues to output when the parking terminal is fixed at the ground or IGN
while the wiper relay is “ON” (INT switch = ON or Washer switch = ON) (The output
stops immediately after turning off the switch) - (1) Wiper MIST and washer coupled wiper
When turning on the washer switch while the wiper relay is operating.
1)
If the wiper relay “ON” request time is shorter than the remained “ON” time, it is
disregarded. -
(2) Speed sensitive INT (intermittent) wiper
The wiper relay continues to output for remaining “ON” time even when the INT switch is
turned off.
IGN 2 switch “ON”, INT switch “OFF”: resume the intermittent time when turning “ON
IGN 2 switch “OFF”, INT switch “ON”: resume the intermittent time when turning “ON 1)

6) Parking Brake Warning
The parking brake warning light comes on for approx. 4 seconds (T4) when turning the ignition key
from “OFF” to “ON” position regardless of the vehicle speed and parking brake switch
position.
The warning light comes on when the parking brake switch is turned on while the vehicle speed is
below 10 km/h (V1).
The warning light goes off when turning off the parking brake switch under step 2.
The warning light blinks and the chime buzzer in the ICM box sounds for 2.85 seconds and stops for
1.5 seconds when the vehicle speed is over 10 km/h (V1) for more than 2 seconds while the parking
brake switch is turned on.
The warning light goes off and the chime buzzer stops when turning off the parking brake switch
under step 4.
The warning light comes on and the chime buzzer stops when the vehicle speed goes down below
7 km/h (V2) under step 4.
This function is not available when the ignition key is turned to “OFF” position. 1.

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 -

1. Overview
The parking aid system (PAS) is a supplementary device which detects the distance to any obstacle
with the ultrasonic sensors equipped to the rear bumper and warns the driver with alarm sounds, when
the vehicle is moving backward.
The system emits the ultrasonic wave signals from the sensors on the rear bumper with a specific
interval and detects the reflected signals from obstacles.
The alarm interval becomes shorter as the obstacle approaches to assure the safety distance and to
facilitate parking of the vehicle.
