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 illustrated.
- This detection zone starts from the back of the vehicle and extends approximately 3.0 m (10 ft) behind the rear bumper, and approximately 13.0 m (10 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.
NOTE:
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.






BSW SYSTEM 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, turn signal and dimmer signal transmitted from BCM via CAN communication:
- Blind Spot Warning indicator signal and Blind Spot Warning indicator dimmer signal transmission to rear view camera.
- Buzzer signal transmission to warning buzzer.
- Rear view camera transmits an indicator operation signal to the Blind Spot Warning indicator according to
Blind Spot Warning indicator signal and Blind Spot Warning indicator dimmer signal.
Operation Condition of BSW System
control unit performs the control when the following conditions are satisfied:
*
- When the warning systems 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.
- After the operating conditions of warning are satisfied, the warning continues until the vehicle speed is reduced below approximately 29 km/h (18 MPH)
- The BSW system may not function properly, depending on the situation.
