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

Do not use the front bumper to push other vehicles or obstructions such as when pulling
out of a parking space. Otherwise, the radar sensor (front) could be hit and its position
deviated.
 Do not remove, disassemble, or modify the radar sensor (front).
 For repairs, replacement or paint work around the radar sensor (front), consult an
Authorized Mazda Dealer.
 Do not modify the suspension. If the suspension are modified, the vehicle's posture could
change and the radar sensor (front) may not be able to correctly detect a vehicle ahead or
an obstruction.
NOTE
Under the following conditions, the radar sensor (front) may not be able to detect vehicles
ahead or obstructions correctly and each system may not operate normally.
The rear surface of a vehicle ahead does not reflect radio waves effectively, such as an
unloaded trailer or an automobile with a loading platform covered by a soft top,
vehicles with a hard plastic tailgate, and round-shaped vehicles.
Vehicles ahead with low vehicle height and thus less area for reflecting radio waves.
Visibility is reduced due to a vehicle ahead casting off water, snow, or sand from its tires
and onto your windshield.
The trunk/luggage compartment is loaded with heavy objects or the rear passenger
seats are occupied.
Ice, snow, or soiling is on the front surface of the front emblem.
During inclement weather such as rain, snow, or sand storms.
When driving near facilities or objects emitting strong radio waves.
Under the following conditions, the radar sensor (front) may not be able to detect vehicles
ahead or obstructions.
The beginning and end of a curve.
Roads with continuous curves.
Narrow lane roads due to road construction or lane closures.
The vehicle ahead enters the radar sensor's blind spot.
The vehicle ahead is running abnormally due to accident or vehicle damage.
Roads with repeated up and down slopes
Driving on poor roads or unpaved roads.
The distance between your vehicle and the vehicle ahead is extremely short.
A vehicle suddenly comes close such as by cutting into the lane.
To prevent incorrect operation of the system, use tires of the same specified size,
manufacturer, brand, and tread pattern on all four wheels. In addition, do not use tires
with significantly different wear patterns or tire pressures on the same vehicle (Including
the temporary spare tire).
If the battery power is weak, the system may not operate correctly.
