2019 MAZDA MODEL CX-30 warning lights

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 4-216.
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:
xThe system detects a vehicle or the
headlights/lights of a vehicle
approaching in the opposite
direction.
xThe vehicle is driven on roads lined
with streetlamps or on roads in
well-lit cities and towns.
xThe vehicle is driven at less than
about 20 km/h (12 mph).
xThe headlight high-beam indicator
light turns on while the high beams
are on.
1. Forward Sensing Camera (FSC)*1
*1 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 High Beam Control System
(HBC) Warning Indication/Warning
Light (Amber) on page 7-58.
CAUTION
¾Do not adjust the vehicle height,
modify the headlight units, or
remove the camera, otherwise the
system will not operate normally.
¾Do 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.
xWhen there are sources of light in
the area such as street lamps,
illuminated signboards, and traffic
signals.
xWhen there are reflective objects in
the surrounding area such as
reflective plates and signs.
xWhen visibility is reduced under rain,
snow and foggy conditions.
xWhen driving on roads with sharp
turn or hilly terrain.
xWhen the headlights/rear lamps of
vehicles in front of you or in the
opposite lane are dim or not
illuminated.

after rain, or there are puddles on
the road.
xThe width of a lane is excessively
narrow.
xThe vehicle is driven on roads with
tight curves.
xHeavy luggage is loaded in the
luggage compartment or on the rear
seat causing the vehicle to tilt.
xThe vehicle is driven through a fork in
the road or a junction.
xThe shade of a guardrail parallel to a
white (yellow) lane line is cast on the
road.

xThe road is excessively uneven.xThe vehicle is shaken after hitting a
road bump.
xA vehicle in front of your vehicle is
running near a white (yellow) lane
line making it less visible.
xThe windscreen is dirty or foggy.xStrong light is directed from the front
of the vehicle (such as sunlight, or
headlights (high-beam) of
on-coming vehicles).
xThe vehicle is driven through an
intersection or a roundabout.
▼When the System Operates
When the ignition is switched ON, the
i-ACTIVSENSE status symbol (warning/
risk avoidance support system) (white)
turns on and the system goes on
standby.
NOTE
If the i-ACTIVSENSE status symbol
(warning/risk avoidance support
system) (white) does not turn on, the
system is cancelled using the
i-ACTIVSENSE switch or the
personalisation feature.

When all of the following conditions
are met, the i-ACTIVSENSE status
symbol (warning/risk avoidance
support system) on the
multi-information display changes
from white to green and the system
becomes operational.
xThe ignition is switched ON.xThe vehicle speed is about 60 km/h
(37 mph) or faster.
xThe system detects white (yellow)
lane lines.
NOTE
When the system does not detect a
white (yellow) lane line on one side
only, the system does not operate on
the side that is not being detected.
When temporarily cancelling the
system
The LDWS goes on standby in the
following cases: The LDWS operation
is automatically restored when the
system's operation conditions are met.

sensing camera (FSC) is foggy.
xThe windscreen around the forward
sensing camera (FSC) is blocked by
an obstruction, causing poor forward
visibility.
xStrong light (such as sunlight, or
headlights (high-beam) of
on-coming 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-ACTIVSENSE
warning indication/warning light on

2. Detection areas
WARNING
Always check the surrounding area
visually before making an actual lane
change:
The system is only designed to assist
you in checking for vehicles at your rear
when making a lane change. Due to
certain limitations with the operation
of this system, the BSM warning
indicator light, the warning sound and
the warning screen indicator display
may not activate or they might be
delayed even though a vehicle is in an
adjacent driving lane. Always make it
your responsibility as a driver to check
the rear.
NOTE
xThe BSM will operate when all of the
following conditions are met:
xThe ignition is switched ON.xThe i-ACTIVSENSE warning
indication/warning light in the
instrument cluster is turned off.
xThe vehicle speed is about 30
km/h (19 mph) or faster.
xThe BSM will not operate under the
following circumstances.
xThe vehicle speed falls below
about 25 km/h (15 mph) even
though the i-ACTIVSENSE warning
indication/warning light is turned
off.
xThe shift lever (manual
transmission)/selector lever
(automatic transmission) is shifted
to reverse (R) and the vehicle is
reversing.
xThe turning radius is small (making
a sharp turn, turning at
intersections).
xIn the following cases, the
i-ACTIVSENSE warning indication/
warning light turns on and operation
of the system is stopped. If the
i-ACTIVSENSE warning indication/
warning light remains illuminated,
have the vehicle inspected at an
expert repairer (we recommend an
Authorised Mazda Repairer) as soon
as possible.

including the BSM warning
indicator lights is detected.
xA large deviation in the installation
position of a rear side radar sensor
on the vehicle has occurred.
xThere is a large accumulation of
snow or ice on the rear bumper
near a rear side radar sensor.
Remove any snow, ice or mud on
the rear bumper.
xDriving on snow-covered roads for
long periods.
xThe temperature near the rear side
radar sensor becomes extremely
hot due to driving for long periods
on slopes during the summer.
xThe battery voltage has decreased.xUnder the following conditions, the
rear side radar sensor cannot detect
target objects or it may be difficult to
detect them.
xThe rear bumper around the rear
side radar sensor is deformed.

mirrors.
xThe front door glass is fogged or
covered in snow, frost or dirt.
xThe rear side radar sensor of the BSM
may be regulated under the radio
wave related laws of the country
where the vehicle is driven. If this
system is used abroad, it may be
necessary to turn off the system.
Refer to Rear Side Radar Sensor on
page 4-224.
xThe system switches to the Rear

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
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 indicator lights and the
warning buzzer.

the shift lever (manual
transmission) or the selector lever
(automatic transmission) 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.
