2018 MAZDA MODEL 3 HATCHBACK high beam

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 Warning/Indicator Lights on page 4-23.
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 appr oaching 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 lin ed 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 Warning Lights on page 4-24.
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 headlight s between the high beams and low beams manually if
necessary.

NOTE
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.
▼ To Operate the System
The HBC operates to sw
itch the headlights
automatically between high and low
beams after the ignition is switched ON
and the headlight switch is in the AUTO
and high beam position.
The HBC determines t hat it is dark based
on the brightness of the surrounding area.
At the same time, th e HBC indicator light
(green) in the instrument cluster
illuminates.

The HBC determines t hat it is dark based
on the brightness of the surrounding area.
NOTE
When the vehicle speed is about 30 km/h
(19 mph) or more, the headlights
automatically switch to high beams
when there are no vehicles ahead or
approaching in the opposite direction.
When the vehicle speed is less than
about 20 km/h (12 mph), the HBC
switches the headlights to low beams.
The low beams may not switch to high
beams when cornering.
Operation of the HBC function can be
disabled. Refer to Personalization
Features on page 9-12.

Forward Sensing Camera (FSC)
Your vehicle is equipped with a Forward Sensing Camera (FSC). The Forward Sensing
Camera (FSC) is positioned near t he rearview mirror and used by the following systems.
High Beam Control System (HBC)
Lane-keep Assist System (LAS) & Lane Departure Warning System ( LDWS)
Traffic Sign Recognition System (TSR)
Smart City Brake Support (SCBS)
Smart Brake Support (SBS)
Forward Sensing Camera (FSC)
The Forward Sensing Camera (FSC) determines the conditions ahead of the vehicle while
traveling at night and detects traffic lanes. The distance in w hich the Forward Sensing
Camera (FSC) can detect objects varies depending on the surroun ding conditions.
WA R N I N G
Do not modify the suspension:
If the vehicle height or inclination is changed, the system will not be able to correctly detect
vehicles ahead. This will result in the system not operating normally or mistakenly operating,
which could cause a serious accident.
CAUTION
 Do not apply accessories, stickers or film to the windshield near the Forward Sensing
Camera (FSC).
If the area in front of the Forward Sensing Camera (FSC) lens is obstructed, it will cause the
system to not operate correctly. Consequently, each system may not operate normally
which could lead to an unexpected accident.

Do not disassemble or modify the Forward Sensing Camera (FSC).
Disassembly or modification of the Forward Se nsing Camera (FSC) will cause a malfunction
or mistaken operation. Consequently, each system may not operate normally which could
lead to an unexpected accident.
 Heed the following cautions to assure the correct operation of the Forward Sensing Camera
(FSC).
 Be careful not to scratch the Forward Sensing Camera (FSC) lens or allow it to get dirty.
 Do not remove the Forward Sensing Camera (FSC) cover.
 Do not place objects on the dashboard which reflect light.
 Always keep the windshield glass around the camera clean by removing dirt or fogging.
Use the windshield defroster to remove fogging on the windshield.
 Consult an Authorized Mazda Dealer regard ing cleaning the interior side of the
windshield around the Forw ard Sensing Camera (FSC).
 Consult an Authorized Mazda Dealer before performing repairs around the Forward
Sensing Camera (FSC).
 The Forward Sensing Camera (FSC) is installed to the windshield. Consult an Authorized

The Forward Sensing Camera (FSC) includes a function for detecting a soiled windshield
and informing the driver, however, depending on the conditions, it may not detect plastic
shopping bags, ice or snow on the windshield. In such cases, the system cannot accurately
determine a vehicle ahead and may not be able to operate normally. Always drive carefully
and pay attention to the road ahead.
