• The rear view camera can detect vehicles on either side of vehicle within the detection zone shown as illus-
trated.
• This detection zone starts from the outside mirror of vehicle and extends approximately 10 ft (3.0 m) behind
the rear bumper, and approximately 10 ft (3.0 m) sideways.
• The BSW system operates above approximately 32 km/h (20 MPH).
• If the rear view camera detects vehicles in the detection zone, the BSW indicator illuminates.
• If the driver then activates the turn signal, a buzzer will sound twice and the BSW indicator will blink.
NOTE:
A buzzer sounds if the rear view camera have already detected vehicles when the driver activates the turn
signal. If a vehicle comes into the detection zone after the driver activates the turn signal, then only the BSW
indicator blinks and no buzzer sounds.
BSW SYSTEM OPERATION DESCRIPTION
• Camera control unit enables BSW system.
• The camera control unit turns on the BSW system when the warning systems switch is turned ON.
• Rear view camera transmits the camera image signal to camera control unit via communication line.
• Camera control unit starts the control as follows, based on a camera image signal, turn signal and dimmer
signal transmitted from BCM via CAN communication:
- Buzzer output signal transmission to combination meter via CAN communication.
• Camera control unit transmits an indicator operation signal to the BSW indicator according to BSW indicator
signal and BSW dimmer signal.
Operation Condition of BSW System
Camera control unit performs the control when the following conditions are satisfied.
• When the warning systems switch in turned ON
*
.
• When the vehicle drives at 32 km/h (20 MPH) or more to the forward direction.
NOTE:
*: When the BSW system setting on the navigation screen is ON.
• After the operating conditions of warning are satisfied, the warning continues until the vehicle speed reaches
approximately 29 km/h (18 MPH)

• When receiving a rear view camera washer activation signal, the pump control unit simultaneously activates
the washer pump to clean the rear view camera by spraying washer fluid from the nozzle installed to the rear
view camera bracket.
• The washer switching solenoid valve switches the washer path from rear window to rear view camera.
• When receiving a rear view camera air blow signal, the pump control unit activates the air pump to clean the
rear view camera by blowing air from the nozzle installed to the rear view camera bracket.
OPERATION CONDITION
• Approximately 30 km/h (20 MPH) or more
• When the camera control unit judges that the rear view camera has water droplets.
• When the front washer and the rear washer are not activated.
• When the low washer fluid warning is OFF.
NOTE:
The camera is cleaned intermittently by spraying washer fluid and blowing air. When the camera 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 BSW is canceled.
