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.

Tolerance± 5 cm ± 5 cm ± 5 cm
5) Distance calibration by temperature from temperature sensor
The ultrasonic wave sensor directs the distance value by receiving the sensor operating temperature
from the sensor and compensating for the detecting deviation since it varies depending on the ambient
temperature.
