drive the vehicle while paying sufficient
attention to safety. Switch the headlights
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 insufficient darkness such
as at dawn or dusk.
When the trunk/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 switch the headlights
automatically between high and low
beams after the ignition is switched ON
and the headlight switch is in the AUTO
and low 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.

NOTE
Operation of the HBC function can be
disabled.
Refer to the Settings section in the Mazda

CAUTION
Heed the following precautions to assure
correct operation of each system.
Do not adhere stickers (including
transparent stickers) to the surface of the
radiator grille and front emblem in and
around the front radar sensor, and do
not replace the radiator grille and front
emblem with any product that is not a
genuine product designed for use with
the front radar sensor.
 The front radar sensor includes a
function for detecting soiling of the radar
sensor's front surface and informing the
driver, however, depending on the
conditions, it may require time to detect
or it may not detect plastic shopping
bags, ice or snow. If this occurs, the
system may not operate correctly,
therefore always keep the front radar
sensor clean.
 Do not install a grille guard.
 If the front part of the vehicle has been
damaged in a vehicle accident, the
position of the front radar sensor may
have moved. Stop the system
immediately and always have the vehicle
inspected at an Authorized Mazda
Dealer.
 Do not use the front bumper to push
other vehicles or obstructions such as
when pulling out of a parking space.
Otherwise, the front radar sensor could
be hit and its position deviated.
 Do not remove, disa ssemble, or modify
the front radar sensor.
 For repairs, replacement or paint work
around the front radar sensor, consult an
Authorized Mazda Dealer.
Do not modify the suspension. If the
suspension are modified, the vehicle's
posture could change and the front
radar sensor may not be able to correctly
detect a vehicle ahead or an obstruction.
NOTE
Under the following co nditions, the front
radar sensor 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 co nditions, the front
radar sensor may not be able to detect
vehicles ahead or obstructions.
The beginning and end of a curve.
Roads with continuous curves.
