Adaptive Front LightingSystem (AFS)
*
▼Adaptive Front Lighting System
(AFS)
The adaptive front lighting system
(AFS) automatically adjusts the
headlight beams to the left or right in
conjunction with the operation of the
steering wheel after the headlights
have been turned on and the vehicle
speed is about 2 km/h (2 mph) or
higher.
A system malfunction or operation
conditions are indicated by a warning.
Refer to Exterior Light Warning
Indication/Warning Light on page
7-34.
NOTE
The Adaptive Front Lighting System
(AFS) can be switched to on/o
ff using
the personalization function.
Refer to the Settings section in the
Mazda Connect Owner's Manual.
High Beam Control
System (HBC)
*
▼ 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 Forward Sensing Camera
(FSC) on page 4-203.
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).
The headlight high-beam indicator
light turns on while the high beams
are on.

*1 The recognition distance of the ForwardSensing Camera (FSC) varies according to
the surrounding conditions.
The warning light turns on when the
system has a malfunction.
Refer to High Beam Control System
(HBC) Warning Indication/Warning
Light (Amber) on page 7-34.
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
su fficient 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 tra ffic conditions.
When there are sources of light in
the area such as street lamps,
illuminated signboards, and tra ffic
signals.
When there are re flective objects in
the surrounding area such as
re flective 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 insu fficient 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 that it is dark
based on the brightness of the
surrounding area. At the same time,
the 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 Connect Owner's Manual.

WARNING
Do not rely completely on the LDWS:
 The LDWS system is not designed to
compensate for a driver’s lack of
caution and relying too much on the
system could lead to an accident.
 The functions of the LDWS have
limitations. Always stay on course
using the steering wheel and drive
with care.
CAUTION
Heed the following cautions so that
the LDWS can operate normally.
Do not modify the vehicle's
suspensions.
 Always use tires of the speci fied type
and size for the front and rear
wheels. Consult an Authorized
Mazda Dealer for tire replacement.
NOTE
The system may not operate normally
under the following conditions.

visible because of bad weather (rain,
fog , or snow).
The vehicle is driven on a temporary
lane or section with a closed lane
resulting from construction where
there might be multiple white
(yellow) lane lines, or they are
interrupted.
The camera picks up an obscure line,
such as a temporary line being used
for construction, or because of
shade, unmelted snow, or grooves
filled with water.
The surrounding brightness suddenly
changes such as when entering or
exiting a tunnel.
Back-light is re flected off the road
surface.
The road surface is wet and shiny
after rain, or there are puddles on
the road.
The width of a lane is excessively
narrow.
The vehicle is driven on roads with
tight curves.
Heavy luggage is loaded in the
trunk/luggage compartment or on
the rear seat causing the vehicle to
tilt.
The vehicle is driven through a fork in
the road or a junction.
The shade of a guardrail parallel to a
white (yellow) lane line is cast on the
road.
The illumination of the headlights is
weakened because of dirt or the
optical axis is deviated at night.
The road is excessively uneven.The vehicle is shaken after hitting a
road bump.
A vehicle in front of your vehicle is
running near a white (yellow) lane
line making it less visible.
The windshield is dirty or foggy.Strong light is directed from the front
of the vehicle (such as sunlight, or
headlights (high-beam) of

The RCTA system is designed to assist
the driver in checking the area to the
rear left and right sides of your vehicle
while your vehicle is reversing by
alerting the driver to the presence of
vehicles approaching the rear of your
vehicle.
The RCTA system detects vehicles
approaching from the rear left and

WARNING
Always check the surrounding area
visually before actually putting the
vehicle in reverse:
The system is only designed to assist
you in checking for vehicles at the rear
when putting the vehicle in reverse.
Due to certain limitations with the
operation of this system, the Blind Spot
Monitoring (BSM) warning indicator
lights may not flash or it might be
delayed even though a vehicle is
behind your vehicle. Always make it
your responsibility as a driver to check
the rear.
RCTA operation
1. The RCTA system operates when the shift lever (manual
transmission) or the selector lever
(automatic transmi ssion) is shifted
to the reverse (R) position.
2. If there is the possibility of a collision with an approaching
vehicle, the Blind Spot Monitoring
(BSM) warning indicator lights
flashes and the warning beep is
activated simultaneously.
