High Beam Control System (HBC) *
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 on page 4-24 .
While driving the vehicle at a speed of about 30 km/h (19 mph), 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:
 


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


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


y 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 À ashes when the system has a malfunction.
Refer to Warning Lights on page 4-25 .
CAUTION
 


¾ Do not adjust the vehicle height, modify the headlight units, or remove the camera,
otherwise the system will not operate normally.
 


¾ Do not rely excessively on the High Beam Control System (HBC) and drive the vehicle while
paying suffi cient attention to safety. Switch the headlights between the high beams and
low beams manually if necessary.

N O T E
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 traf¿ c
conditions.
 


y When there are sources of light in the area such as street lamps, illuminated signboards,
and traf¿ c signals.




y When there are reÀ ective objects in the surrounding area such as reÀ ective plates and
signs.
 


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



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



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


y When there is suf¿ cient darkness such as at dawn or dusk.



y When the luggage compartment is loaded with heavy objects or the rear passenger seats

To Operate the System
The High Beam Control System (HBC)
operates to switch 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 High Beam Control System (HBC)
determines that it is dark based on the
brightness of the surrounding area. At the
same time, the High Beam Control System
(HBC) indicator light (green) in the
instrument cluster illuminates.



N O T E
 


y When the vehicle speed is 30 km/h
(19 mph) or higher, 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 High Beam
Control System (HBC) switches the
headlights to low beams.
 


y The low beams may not switch to high
beams when cornering.
 


y Operation of the High Beam Control
System (HBC) function can be disabled.
Refer to Personalization Features on
page 9-10 .

Manual Switching
Switching to low beams
Shift the lever to the low beam position.
The High Beam Control System (HBC)
indicator light (green) turns off.
Switching to high beams
Turn the headlight switch to the

position.
The High Beam Control System (HBC)
indicator light (green) turns off and the

is illuminated.

y The Smart City Brake Support (SCBS) detects a vehicle ahead by emitting a near-infrared
laser beam and receiving the beam reÀ ected off the reÀ ector of the vehicle ahead, and
then using it for the measurement. Consequently, the Smart City Brake Support (SCBS)
may not operate under the following conditions:
 


y ReÀ ection of the laser is poor due to the shape of the vehicle ahead.



y The vehicle ahead is signi¿ cantly dirty.



y Under bad weather condition, such as rain, fog and snow.



y The window washer is being used or the windshield wipers are not used when it's
raining.
 


y The windshield is dirty.



y The steering wheel is turned completely left or right, or the vehicle is accelerated
rapidly and comes close to the vehicle ahead.
 


y Trucks with low loading platforms and vehicles with an extremely low or high pro¿ le.



y Vehicles with certain shapes such as a vehicle carrier. 



y Under the following conditions, the Smart City Brake Support (SCBS) system may not
operate normally.
 


y Heavy luggage is loaded in the luggage compartment or on the rear seat.



y If there is the possibility of partial contact with a vehicle ahead.



y When driving on continuously curving roads, and entering and exiting exits.



y Elongated luggage or cargo is loaded onto installed roof rails and covers the laser
sensor (front).
 


y Exhaust gas from the vehicle in front, sand, snow, and water vapor rising from
manholes and grating, and water splashed into the air.
 


y When towing a malfunctioning vehicle.



y When driving with tires having signi¿ cantly different wear. 



y In the following cases, the laser sensor (front) may inadvertently determine that there is a
vehicle ahead and the Smart City Brake Support (SCBS) system may operate.
 


y Objects on the road at the entrance to a curve.



y Vehicles passing in the opposite lane while making a curve.



y Metal objects, bumps, or protruding objects on the road.



y When passing through a toll gate equipped with a bar.



y When passing under a vinyl curtain or À ag.



y Plastic objects such as pylons.



y Two-wheeled vehicles, pedestrians, animals or standing trees. 



y When the system operates, the user is noti¿ ed by the À ashing Smart City Brake Support
(SCBS) indicator light (red) and the active driving display * . 


y The Smart City Brake Support (SCBS) warning light (amber) turns on when the system
has a malfunction.

CAUTION
 


¾ Do not apply accessories, stickers or fi lm 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.
 


¾ Do not disassemble or modify the Forward Sensing Camera (FSC).
 Disassembly or modifi cation of the Forward Sensing Camera (FSC) will cause a malfunction
or mistaken operation. Consequently, each system may not operate normally which could
lead to an unexpected accident.
 


¾ Heed the following cautions to assure the correct operation of the Forward Sensing Camera
(FSC).
 


¾ The direction of the Forward Sensing Camera (FSC) has been fi nely adjusted, therefore
do not change the installation position or remove the Forward Sensing Camera (FSC).
 


¾ Be careful not to scratch the Forward Sensing Camera (FSC) lens or allow it to get dirty.



¾ Do not remove the Forward Sensing Camera (FSC) cover.



¾ Do not place objects on the dashboard which refl ect light.



¾ Always keep the windshield glass around the camera clean by removing dirt or fogging.
Use the windshield defroster to remove fogging on the windshield.
 


¾ Consult an Authorized Mazda Dealer regarding cleaning the interior side of the
windshield around the Forward Sensing Camera (FSC).
 


¾ Consult an Authorized Mazda Dealer before performing repairs around the Forward
Sensing Camera (FSC).
 


¾ The Forward Sensing Camera (FSC) is installed to the windshield. Consult an Authorized
Mazda Dealer for windshield repair and replacement.
 


¾ When performing repairs around the rearview mirror, consult an Authorized Mazda
Dealer.
 


¾ Do not hit or apply strong force to the Forward Sensing Camera (FSC) or the area around
it. If strong force is applied, stop using the Lane Departure Warning System (LDWS), the
High Beam Control System (HBC), and the Smart Brake Support (SBS) and consult an
Authorized Mazda Dealer.
 


¾ The direction in which the Forward Sensing Camera (FSC) is pointed has been fi nely
adjusted. Do not change the installation position of the Forward Sensing Camera (FSC)
or remove it. Otherwise, it could result in damage or malfunction.
