• The around view monitor control unit controls the around view
monitor with Park Assist. (Perpendicular parking)
• The around view monitor control unit is located in the rear of the
glove box.
• It sends and receives the necessary signals to/from each ECU via
CAN communication.
• Power is supplied to each camera when the ignition switch is ON.
• The camera image signals received from the cameras are con-
verted and combined within the around view monitor control unit
and then sent to the NAVI control unit.

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.
