DESCRIPTION 

Operation Description 

• When the selector lever is shifted to the reverse position, the rear view monitor image is displayed.
• When the selector lever is shifted to any position other than the reverse position, the original image (the image displayed before the rear view monitor image) is displayed.

Camera Image Operation Principle 

• The AV control unit that receives the reverse signal input supplies power to the rear view camera and gives input of image signal.
• The AV control unit outputs the rear view camera image to the display unit when the reverse signal is input.
• The AV control unit generates the warning message, vehicle width guide lines and the predicted course lines on the image from the rear view camera and transmits the rear view camera image signal to the display unit.

Vehicle Width Guide Lines and Predicted Course Lines Display Function at Rear View Monitor Display 

• The vehicle width guide lines and the predicted course lines that indicate the vehicle route according to the steering angle are displayed on the rear view monitor display to allow the driver to more easily judge distances between the vehicle and objects and help the driver back into a parking space.
• The AV control unit receives the steering signal from the steering angle sensor via CAN communication and draws a vehicle width guide line according to the steering angle.
• When the vehicle width guide lines are displayed, the vehicle width guide lines are displayed translucently.
• The predicted course lines are not displayed when the steering wheel is in the neutral position.

Precautions for Vehicle Width Guide Lines and Predicted Course Lines Display on the Rear View Monitor Display 

Vehicle width guide lines and predicted course lines on the display may be different from actual lines depending on vehicle conditions and road conditions. Precautions for road conditions

• Since vehicle width guide lines and predicted course lines are drawn based on the road, a different distance may be displayed if a protruding block is present nearby.

CAMERA ASSISTANCE SONAR FUNCTION 

• Sonar sensors are installed on front and rear bumpers. When an obstacle is detected while rear camera is displayed, a sonar indicator display and buzzer sound notify the driver of the proximity of an obstacle. When an obstacle is detected while rear view camera is not displayed, rear view camera screen is displayed automatically, and then notification is similar as while rear view camera is displayed.
• Approaching distance between bumper and obstacle is displayed in 3 stages according to the color of the sonar indicator in display and blinking cycle of indicator.
• Warning by buzzer sound notifies distance to obstacle according to a 3-stage cycle.
