High Beam Control System (HBC)

The HBC determines the conditions in front of the vehicle using the Forward Sensing Camera (FSC) while driving in darkness to automatically switch the headlights between high and low beams.

 

  • Do not adjust the vehicle height, modify the headlight units, or remove the camera, otherwise the system will not operate normally.

  • Do not rely excessively on the HBC and drive the vehicle while paying sufficient attention to safety. Switch the headlights between the high beams and low beams manually if necessary.

  • The distance in which the HBC can detect objects varies depending on the surrounding conditions.

  • The Forward Sensing Camera (FSC) may not be able to detect target objects correctly, and the system may not operate normally.

    Refer to Forward Sensing Camera (FSC) (Search).

The system switches the headlights to low beams when one of the following occurs:

  • The vehicle is driven at less than about 20 km/h (12 mph).

  • The system detects a vehicle or the headlights/lights of a vehicle approaching in the opposite direction.

  • The vehicle is driven on roads lined with streetlamps or on roads in well-lit cities and towns.

  • The headlight high-beam indicator light turns on while the high beams are on.

While driving the vehicle at a speed of about 30 km/h (19 mph) or more, the headlights are switched to high beams when there are no vehicles ahead or approaching in the opposite direction.
