FUNCTION DESCRIPTION
  • The Blind Spot Warning (BSW) system can help alert the driver of other vehicles in adjacent lanes when changing lanes.
  • The BSW system uses side radar installed near the rear bumper to detect vehicles in an adjacent lane.
  • The side radar can detect vehicles on either side of vehicle within the detection zone shown as illustrated.
  • 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 10 km/h (6.2 MPH).
  • If the side radar detects vehicles in the detection zone, the BSW indicator illuminates.
  • If the driver then activates the turn signal, a buzzer sounds twice and the BSW indicator blinks.
    noteA buzzer sounds if the side radar 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.
 
 
OPERATION DESCRIPTION
  • Side radar enables BSW system.
  • The side radar turns on the BSW system when the turned ON by information display.
  • Side radar detects a vehicle in the adjacent lane.
  • Side radar starts the control as follows, based on a vehicle detection signal, turn signal and dimmer signal transmitted from BCM via CAN communication:
    • Transmits BSW indicator signal and BSW indicator dimmer signal to BSW indicator.
    • Transmits a buzzer output signal to combination meter.
 
 
OPERATION CONDITION
Side radar performs the control when the following conditions are satisfied.
  • BSW system: ON
  • Vehicle speed: Approximately 10 km/h (6.2 MPH) or more
note
  • ON/OFF of BSW system is performed with the information display.
  • After the operating conditions of warning are satisfied, the warning continues until the vehicle speed reaches approximately 29 km/h (18 MPH)
  • The BSW system may not function properly, depending on the situation. Refer to Handling Precaution.
 
 
CANCEL CONDITION
The side radar cancels the operation when the system is under any conditions of the operation cancellation condition.
  • When the system malfunction occurs.
  • When the area around the side radar is dirty.
