1. COMPONENT SPECIFICATIONS
The PAS (parking aid system) emits the ultrasonic wave signals from the sensors on the rear
bumper at a specific interval
and detects the reflected signals from obstacles when reversing. The alarm interval increases as
the obstacle approaches.
This supplementary system is useful to measure the distance when parking.
Parking Aid Unit ▶
Parking Aid Sensor ▶
Detecting type: Ultrasonic wave (Piezo
ceramic element)
Calculates the distance between the
sensor and the object by calculating the
return time of the emitted the ultrasonic
wave
Frequency used: 50 KHz ± 1 KHz
Detection distance: 30 cm ~ 120 cm
(based on lineal distance between sensor
and obstacle)
Tolerance: ± 10 cm

2. CAUTIONS
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 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". -

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)

Parking Aid Unit
1. GENERAL INFORMATION
1) Components and Function
The parking aid system uses three
piezoelectric ceramic sensors inside the rear
bumper to measure the vertical and horizontal
distances to the obstacles. The parking aid
system has a separate unit that sends signal
to the buzzer when reverse parking to notify
the driver of the distance to obstacle. When
placing the gear selector lever to “R" position,
this unit activates the sensor to measure the
distance between the object and the bumper.
The existing PAS unit displays the
malfunctions using the LED when there are
any defects in sending/receiving signal or the
open circuit to sensor. On the other hand, the
PAS unit of KORANDO SPORTS informs the
malfunction of the relevant sensor using a
buzzer.

2) EBD (Electronic Brake-force Distribution) Warning Lamp
EBD warning lamps (brake warning lamp and ABS warning lamp) come on when the system
performs the self diagnosis and when it detects the malfunction of EBD system. However, the
brake warning lamp comes on regardless of EBD system when the parking brake is applied.
EBD warning lamp ON:
When turning the ignition switch to ON position, ABS warning lamp and the brake warning
lamp comes on for 3 seconds for self diagnosis and goes off if the system is OK
(initialization mode).
When applying the parking brake, the brake warning lamp comes on.
When the brake fluid is not sufficient, the brake warning lamp comes on.
When disengaging the connector, the warning lamp comes on.
When the system is defective, ABS warning lamp and the brake warning lamp come on
simultaneously. A.
