FUNCTION DESCRIPTION
• The BSW system can help alert the driver of other vehicles in adjacent lanes when changing lanes.
• The BSW system uses rear view camera near the rear bumper to detect vehicles in an adjacent lane.
• 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 back of the vehicle and extends approximately 3.0 m (10.0 ft) behind the
rear bumper, and approximately 3.0 m (10.0 ft) sideways.
• The BSW system operates above approximately 32 km/h (20 MPH).
• If the rear view camera detects vehicles in the detection zone, the blind spot warning indicator illuminates.
• If the driver then activates the turn signal, a buzzer will sound twice and the blind spot warning indicator will
blink.

• The control unit turns on the BSW system when the warning systems switch is turned ON.
• Rear view camera detects a vehicle in the adjacent lane, and transmits the vehicle detection signal to control
unit.
• Control unit starts the control as follows, based on a vehicle detection signal and turn signal transmitted from
BCM via CAN communication:
- Buzzer signal transmission to warning buzzer.
• Around view monitor transmits a blind spot warning indicator signal LH or RH to the blind spot warning indi-
cator LH or RH.

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 pump control unit via
serial communication.
• 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.
• 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 32km/h (20 MPH) 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 BSW is canceled.
