BLIND SPOT MONITOR SYSTEM PRECAUTION


  1. PRECAUTIONS FOR BLIND SPOT MONITOR SYSTEM


    1. The blind spot monitor function may not detect vehicles correctly in the following conditions:


      1. During bad weather such as heavy rain, fog, snow, etc.

      2. When there is a significant difference in speed between this vehicle and the vehicle that enters the detection area.

      3. When a vehicle is in the detection area from a stop and remains in the detection area as this vehicle accelerates.

      4. When driving up or down steep inclines, such as hills, a dip in the road, etc.

      5. When multiple vehicles approach with only a small gap between each vehicle.

      6. When vehicle lanes are wide, and the vehicle in the next lane is too far away from this vehicle.

      7. When the vehicle that enters the detection area is traveling at about the same speed as this vehicle.

      8. When there is a significant difference in height between this vehicle and the vehicle that enters the detection area.

      9. When driving on a road surface that is wet due to rain, standing water, etc.

      10. When ice, mud, etc. is attached to the rear bumper.

      11. Immediately after the blind spot monitor system is turned on.

        Tech Tips

        In this section, the expression "this vehicle" is used to refer to the vehicle equipped with this blind spot monitor system.

    2. The blind spot monitor function is not designed to detect the following types of vehicles or objects:


      1. Vehicles traveling from the opposite direction.

      2. Small motorcycles, bicycles, pedestrians, etc.*

      3. Following vehicles that are in the same lane.*

      4. Guardrails, walls, signs, parked vehicles and similar stationary objects.*

      5. Vehicles driving 2 lanes across from this vehicle.

        Tech Tips

        In this section, the expression "this vehicle" is used to refer to the vehicle equipped with this blind spot monitor system.


        • *: Depending on conditions, detection of a vehicle and/or object may occur.

    3. Instances of the blind spot monitor function unnecessarily detecting a vehicle and/or object may increase under the following conditions:


      1. When there is only a short distance between this vehicle and a guardrail, wall, etc.

      2. When vehicle lanes are narrow and a vehicle driving 2 lanes across from this vehicle enters the detection area.

      3. When there is only a short distance between this vehicle and a following vehicle.

    4. The RCTA function may not detect vehicles correctly in the following conditions:


      1. During bad weather such as heavy rain, fog, snow, etc.

      2. When a vehicle is approaching at high speed.

      3. When multiple vehicles approach continuously.

      4. When parking on a steep incline, such as hills, a dip in the road etc.

      5. Vehicles that the sensors cannot detect because of obstacles.

      6. Shallow angle parking.

      7. When ice, mud, etc. is attached to the rear bumper.

      8. Immediately after the blind spot monitor system is turned on.

    5. The RCTA function is not designed to detect the following types of vehicles or objects:


      1. Vehicles approaching from directly behind.

      2. Vehicles that the sensors cannot detect due to obstructions.

      3. Guardrails, walls, signs, parked vehicles and similar stationary objects.*

      4. Small motorcycles, bicycles, pedestrians, etc.*

      5. Vehicles moving away from this vehicle.

      6. Vehicles approaching from the parking spaces next to this vehicle.*

        Tech Tips

        In this section, the expression "this vehicle" is used to refer to the vehicle equipped with this blind spot monitor system.


        • *: Depending on conditions, detection of a vehicle and/or object may occur.

    6. Instances of the RCTA function unnecessarily detecting a vehicle and/or object may increase under the following condition:


      1. When backing this vehicle into a parking space that faces a road, the function may detect vehicles driving on the road.

        Tech Tips

        In this section, the expression "this vehicle" is used to refer to the vehicle equipped with this blind spot monitor system.

    7. Under the following conditions, the blind spot monitor system may store DTCs C1AC1 and C1AC2 by mistake:


      1. The vehicle is driven continuously with the blind spot monitor system on when using a drum tester such as a speedometer tester, brake/ speedometer combination tester or chassis dynamometer.

  2. HANDLING THE RADAR SENSOR


    1. Blind spot monitor sensors are installed behind the left and right sides of the rear bumper respectively. Observe the following to ensure the blind spot monitor can function correctly.


      1. Keep the sensors and the surrounding areas on the rear bumper clean at all times.

      2. Do not subject a sensor or its surrounding area on the rear bumper to a strong impact. If a sensor is moved even slightly off position, the system may malfunction and vehicles may not be detected correctly. In the following situations, inspect the sensor and surrounding area.


        • A sensor or its surrounding area is subject to a strong impact.

        • If the surrounding area of a sensor is scratched or dented, or part of them has become disconnected.

      3. Do not disassemble the sensor.

      4. Do not attach stickers to the sensor or surrounding area on the rear bumper.

      5. Do not modify the sensor or surrounding area on the rear bumper.

      6. Do not paint the rear bumper any color other than an official Lexus color.

      7. Do not drop a sensor or subject it to a strong impact, as it is a high-precision device.

      8. Do not reuse a sensor that has been dropped or subjected to a strong impact.
