the vehicle on display. The vehicle icon and sonar indica tor that are displayed on the Birds-Eye view display
are rendered by around view monitor control unit.
Around View Monitor Screen
 Around view monitor combines and displays the travel di rection view and “Birds-Eye view”, “Front-Side view”
and then it displays the sonar indicator on the “Birds -Eye view”, “Front-Side view”, “Rear wide view”.
 AV control unit renders the “Change View” switch, view icon, warning message on display.

Operation Description
 Around view monitor operates by pressing the “CAMERA” switch of multifunction switch and shifting the
selector switch to the reverse position.
 When the selector lever is in any position other t han the reverse position, the screen is switched to the
around view monitor by pressing the “CAMERA” switch.
 The screen is switched to the around view monitor by sh ifting the selector lever to the reverse position.
 In the around view monitor, Birds-Eye view, Front-si de view and rear wide view (rear only) can be switched
by pressing the “CAMERA” switch.
 The around view monitor is cancelled 3 minutes af ter pressing the “CAMERA” switch, and then the screen
returns to the screen before displaying the around view monitor when selector lever is in a position other
than the reverse position.
 ON/OFF setting of sonar indicator display on the Front-Side view screen can be performed.
 In the Birds-Eye view, the invisible area is displa yed on the image to specify the boundary of the 4 cameras.
The invisible area is displayed in yellow in the Birds-Eye view after turning the ignition switch ON.
 The sonar (both of buzzer and indicator) operates only when the camera screen is displayed. NOTE:
The first, second, and third camera image displayed when switched to the camera image display depends
on the settings of “Camera View Priority”.

FRONT VIEW The front view image is from the front camera.
 When the selector lever is in any position other than the reverse position, the front view is displayed by
pressing the “CAMERA” switch. It improves the visibility of obstacles in front of the vehicle and helps driving
by the images displayed from Bi rds-Eye view and Front-Side view.
 Display the vehicle width guiding line and vehicle distance guiding line in front view and display the predic- tive course line according to the steering angle.
 If the steering angle is within approximately 90 degrees, t he predictive course lines on the left/right side are
displayed. If the steering angle is exceeding approxim ately 90 degrees, only the predictive course line on the
outside (in the opposite side of steering direction) is displayed.
 AV control unit is connected to the steering angle s ensor and receives the steering angle signal via CAN
communication. AV control unit is transmits steering angle signal to around view monitor control unit via AV
communication.
 Around view monitor control unit controls the directi on and distance of the predictive course line according to
the sensor signal from steering angle sensor.

Camera Image Operation Principle
 If the information writing to around view monitor control unit and the information from the camera are not
matched, the applicable camera position is indicated as an error on the Birds-Eye view display. (Calibration
operation is necessary when replacing each camera or when replacing around view monitor control unit.)
 Around view monitor control unit receives the camera switch signal from AV control unit via AV communica-
tion by pressing the “CAMERA” switch of multifunction switch.
 Around view monitor control unit that receives the ca mera switch signal supplies the power to each camera
and inputs the camera image from each camera.
 When the selector lever is in the reverse position, around view monitor control unit receives the reverse sig- nal, supplies the power to each camera, and inputs the camera image from each camera.
 Around view monitor control unit that receives the camera image signal from each camera cuts out the
required screen for each view, superimposes the camera image, vehicle icon, guiding lines, sonar indicator,
and outputs them to the front display unit.
CAMERA ASSISTANCE SONAR FUNCTION
 Install the corner sensor on the front bumper and r ear bumper. It detects the obstacles around the vehicle
when the around view monitor is displayed. It warn s of the approach to the obstacles with the buzzer and
indicator in the display linked with the around view monitor system.
 It displays the distance between the bumper and obstacle with the color of sonar indicator in the display and the blinking cycle of indicator in 3 stages.
 The buzzer warns of the distance to the obstacles with the cycle in 3 stages.
System Operation Description
 Around view monitor control unit transmits the sonar operation signal via AV communication to sonar control
unit to control the operation of sonar indicator and sonar buzzer.
 Sonar control unit that receives the sonar operation signal from around view monitor control unit transmits
the detection signal and detection distance signal according to the signal from corner sensor via AV commu-
nication to around view monitor control unit. Around vi ew monitor control unit operates the applicable sonar
indicator.
 When receiving a sonar operation signal from the around view monitor control unit, the sonar control unit
converts a signal transmitted from the corner sensor into a detection distance signal and transmits it to the
AV control unit via AV communication. When receivi ng the detection signal, the AV control unit activates
each speaker via BOSE amp.
