PARKING AID SYSTEM
3. OPERATIONS OF PARKING AID SYSTEM(PAS)
1) Alarm interval
Alarm interval and display changes according to the distance as below:
While reversing, if obstacles are within stage 1, the warning beep sounds with long intervals. I
f
within stage 2, the warning beep sounds with short intervals and if within stage 3, the warning
beep sounds continuously.
2) System Trouble Shooting
When the power is applied (gear selector lever is in “R” position), the sensor will be
diagnosed once. If found any failure due to open circuit to sensor or communication error,
warning buzzer sounds for 3 seconds and the data on failed sensor transmits to the instrument
panel to light up the corresponding LED. If normal, the warning buzzer sounds only for 65 ms.
1) Whenever the power is applied, the diagnosis mode is initiated.
2) Sensor failure conditions
(conditions for warning beep due to failure)
(a) Open in sending circuit
(b) Open in receiving circuit
(c) Open in power circuit (+, -)

3) Cautions on parking aid system
Note that the display does not show everything in the rear area.
Always check nobody, especially animals and children, is behind the vehicle.
Normal precautions when reversing should be maintained. *
*
The parking aid system is just a supplemental device to help your parking operation.
Always keep the safety precautions.
Do not press or shock the sensors by hitting or high-pressure water gun while washing, o
r
the sensors will be damaged.
If the system is in normal operating conditions, a short beep sounds when the gear selecto
r
lever is moved into “R” position with the ignition key “ON”.
If the system is in abnormal operating conditions, a beep sounds for 3 seconds when the
gear selector lever is moved into “R” position with the ignition key “ON” or engine
running. However, it is also occurred when the obstacle is within 50 cm from the rea
r
bumper. 1.

(1) The parking aid system will not work or improperly work under
following cases:
▶Certain obstacles that sensors can not detect
- Wires, ropes, chains.
- Cotton, sponge, clothes, snow that absorb ultrasonic waves.
- Obstacles lower than the bumper.
▶Not defective but improperly working
- 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.
▶Narrowed sensing area
- When the sensing portion is partially covered by snow or mud.

▶Not defective but may occur improper working
- When driving on the rough road, gravel road, hill and grass.
- When the bumper height is changed due to the 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

3. ESP SYSTEM DESCRIPTION
1) Principle of ESP
ESP (Electronic Stability Program) recognizes critical driving conditions, such as panic
reactions in dangerous situations, and stabilizes the vehicle by wheel-individual braking and
engine control intervention with no need for actuating the brake. This system is developed to
help the driver avoid the danger of losing the control of the vehicle stability due to under-
steering or over-steering during cornering.
The yaw rate sensor, lateral sensor and longitudinal sensor in the sensor cluster and the
steering wheel angle sensor under the steering column detect the spin present at any wheels
during over-steering, under-steering or cornering. The ESP ECU controls against over-steering
or under-steering during cornering by controlling the vehicle stability using the input values from
the sensors and applying the brakes independently to the corresponding wheels.
The system also controls during cornering by detecting the moment right before the spin and
automatically limiting the engine output (coupled with the ASR system).
Understeering is when the steering wheel is
steered to a certain angle during driving and
the front tires slip toward the reverse
direction of the desired direction. Generally,
vehicles are designed to have unde
r
steering. The vehicle can return back to
inside of cornering line when the steering
wheel is steered toward the inside even
when the vehicle front is slipped outward.
As
the centrifugal force increases, the tires can
easily lose the traction and the vehicle tends
to slip outward when the curve angle gets
bigger and the speed increases. Under steering
ESP controls during under steering
The ESP system recognizes the directional
angle with the steering wheel angle senso
r
and senses the slipping route that occurs
reversely against the vehicle cornering
direction during understeering with the yaw
rate sensor and the lateral sensor. Then the
ESP system applies the brake at the rea
r
inner wheel to compensate the yaw moment
value.
In this way, the vehicle does not lose its
driving direction and the driver can steer the
vehicle as driver intends.
