High Beam Control System (HBC); When Driving- Page 203

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.
Refer to Forward Sensing Camera (FSC) on page 4-103.
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).

Forward Sensing 
Camera (FSC)

The recognition distance of the 
Forward Sensing Camera (FSC) 
varies according to the 
surrounding conditions.

The warning light turns on when the system has a malfunction.
Refer to Contact Authorized Mazda Dealer and Have Vehicle Inspected on page 7-36.

CAUTION



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.
