High Beam Control System (HBC) (Some Models)

The High Beam Control System (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.

Refer to Warning/Indicator Lights (Search).

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.

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

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

The warning light turns on when the system has a malfunction.

Refer to Warning Indication/Warning Lights (Search).


  • 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 High Beam Control System (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 timing in which the system switches the headlights changes under the following conditions. If the system does not switch the headlights appropriately, manually switch between high and low beams according to the visibility as well as road and traffic conditions.

  • When there are sources of light in the area such as street lamps, illuminated signboards, and traffic signals.

  • When there are reflective objects in the surrounding area such as reflective plates and signs.

  • When visibility is reduced under rain, snow and foggy conditions.

  • When driving on roads with sharp turn or hilly terrain.

  • When the headlights/rear lamps of vehicles in front of you or in the opposite lane are dim or not illuminated.

  • When there is sufficient darkness such as at dawn or dusk.

  • When the luggage compartment is loaded with heavy objects or the rear passenger seats are occupied.

  • When visibility is reduced due to a vehicle in front of you spraying water from its tires onto your windshield.
