*Some models.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 darknes s to automatically switch
the headlights between high and low beams.
Refer to Warning/Indicator Lights on page 4-18 .
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 Warning Indication/Warning Lights on page 4-26 .
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 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.

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. 

i-ACTIVSENSE To Operate the SystemThe 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.
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 High Beam
Control System (HBC) switches the
headlights to low beams. 
The low beams may not switch to high
beams when cornering. 
Operation of the High Beam Control
System (HBC) function can be disabled.
Refer to Personalization Features on
page 9-9 . 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.

Owner MaintenanceReplacing the fuses under the hood
If the headlights or other electrical
components do not work and the fuses
in the cabin are normal, inspect the fuse
block under the hood. If a fuse is blown, it
must be replaced. Follow these steps:
1. Make sure the ignition is switched off,
and other switches are off.
2. Remove the fuse block cover.
NOTE
If the lock is forcefully opened, the fuse
block cover may come in contact with the
frame when it is removed and become
scratched.
When removing the cover, remove it slowly
according to the following procedure.
1. Disengage the rear lock by pressing
down on the front tab with your
fingers.
2. Remove the front tab while slightly
lifting the front of the cover. 3. Remove the cover while lifting it and
sliding it to the rear.
3. If any fuse but the MAIN fuse is
blown, replace it with a new one of the
same amperage rating .
Normal
Blown
WARNING Do not replace the main fuse and
multiplex slow blow fuse by yourself.
Have an Authorized Mazda Dealer
perform the replacement:
Replacing these fuses by yourself is
dangerous because they are high
current fuses. Incorrect replacement
could cause an electrical shock or a
short circuit resulting in a fire.
4. Reinstall the cover and make sure that
it is securely installed.
