lights MAZDA MODEL 3 HATCHBACK 2020 (in English) Owner's Guide

*1 The recognition distance of the Forward SensingCamera (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 ve hicle 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 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
Connect Owner's Manual.

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 wheels of the
specified 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.
The white (yellow) lane lines are less
visible because of di rt or paint flaking.
White (yellow) lane lines are less 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 reflected 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 on-coming
vehicles).
The vehicle is driven through an
intersection or a roundabout.

vehicles) is directed at the forward
sensing camera (FSC).
System malfunction
If there is a problem with the system, the
i-ACTIVSENSE status symbol (warning/
risk avoidance support system) (white)
and the i-ACTIV SENSE warning
indication/warning light on the
multi-information display turns on and a
message is indicated.
Refer to i-ACTIVSENSE Status Symbol
(Warning/Risk Avoidance Support

▼ LDWS Warning
If the system determines that the vehicle
may deviate from its lane, a warning (beep
sound, steering wheel vibration) is
activated and the direction in which the
system determines that the vehicle may
deviate is indicated on the
multi-information display.
NOTE
The LDWS settings can be changed.
Refer to the Settings section in the
Mazda Connect Owner's Manual.
You may not be able to hear the LDWS
warning sound depending on the
surrounding conditions such as outside
noise.
If you set the LDWS to vibrate the
steering wheel, you may not feel the
vibrations depending on the road
surface conditions.
▼Canceling the System
The LDWS can be set to inoperable.
(If only the LDWS is turned off)
Refer to the Settings section in the
Mazda Connect Owner's Manual.
(If the LDWS is
turned off by
operating the i-ACTIVSENSE switch)
Refer to i-ACTIV SENSE Switch on
page 4-87.

▼Rear Cross Traffic Alert (RCTA)
The RCTA system is des
igned 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 right
sides of your vehicle and the rear of your
vehicle while your vehicle is being
reversed out of a parking space, and
notifies the driver of possible danger using
the Blind Spot Monitoring (BSM) warning

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.
