SYSTEM

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.

A buzzer sounds if the rear view camera has 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 blind
spot warning indicator blinks and no buzzer sounds.

OPERATION DESCRIPTION

• Control unit enables BSW system.
• 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.

Operation Condition of BSW System

 control unit performs the control when the following conditions are satisfied:
• When the warning system switch is turned ON

*

.

• When the vehicle drives at 32 km/h (20 MPH) or more in the forward direction.
NOTE:
*: When the BSW system setting on the vehicle information display screen is ON.

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.
