Possible malfunction

NOTE:
  • The system may not operate normally under the following conditions:
    • The rear bumper near the blind spot monitoring (BSM) control module has become deformed.
    • Snow, ice or mud adheres to the blind spot monitoring (BSM) control module on the rear bumper
    • Under bad weather conditions such as rain, snow and fog.
    • Stationary objects on a road or a road side such as small, two-wheeled vehicles, bicycles, pedestrians, animals, and shopping carts.
    • Vehicle shapes which do not reflect radar waves well such as empty trailers with a low vehicle height and sports cars.
  • Turn off the system while pulling a trailer or while an accessory such as a bicycle carrier is installed to the rear of the vehicle. Otherwise, the radio waves emitted by the radar will be blocked causing the system to not operate normally.
