Output Signal Item

FUNCTION DESCRIPTION

• The around view monitor with Park Assist (PA) is designed to assist drivers with perpendicular and parallel

parking. This system operates the steering wheel to park the vehicle in the parking space set by the driver on
the around view monitor screen (perpendicular mode), or searched by parking sensors (sonar) in the left/
right side of the front bumper (parallel mode). Screen guidance for the shift lever operation is also provided
during the parking maneuvers.

• When the system is operating, the conditions surrounding the vehicle are displayed on the around view

monitor screen, and at the same time the predicted course line, forward/reverse starting position rectangle
(perpendicular parking), and other information is also displayed.
