• The around view monitor control unit enables LDW system.

• When the system is turned ON, the around view monitor control unit transmits a LDW system display signal

to combination meter via CAN communication.

• Rear view camera monitors the traveling lane. It transmits the camera image signal to around view monitor

control unit.

• When judging from a camera image signal that the vehicle is approaching the lane marker, the around view

monitor control unit controls the following item to alert the driver.

- Activates the warning system buzzer.

- Around view monitor control unit transmits a LDW system signal to combination meter via CAN communica-

tion and blinks the LDW system indicator (“icon”).

Operating Condition

• LDW indicator: ON

• Warning systems indicator: ON

• Vehicle speed: approximately 45 MPH (70 km/h) or more.

SYSTEM

REAR VIEW CAMERA WASHER OPERATION

• When judging that the rear view camera has water droplets, the around view monitor control unit transmits a

rear view camera washer activation signal or rear view camera air blow signal to the rear view camera

washer control unit via serial communication. 

• When receiving a rear view camera washer signal, the rear view camera washer control unit simultaneously

activates the rear view camera washer motor to clean the rear view camera by spraying washer fluid from

the nozzle installed to the rear view camera bracket.

• When receiving a rear view camera air blow signal, the rear view camera washer control unit activates the

rear view camera air pump motor to clean the rear view camera by blowing air from the nozzle installed to

the rear view camera bracket.

OPERATION CONDITION

• Approximately 20 MPH (30 km/h) or more.

• When the around view monitor control unit judges that the rear view camera has water droplets.

• When the low washer fluid warning is OFF.

NOTE:

The camera is cleaned intermittently by spraying washer fluid and blowing air. When the around view monitor

control unit judges that dirt on the camera cannot be removed even after approximately 5 minutes from the

first detection of dirt, the activation of LDW is canceled.
