warning lights MAZDA MODEL 3 HATCHBACK 2020 (in English) User Guide

If the low fuel warning light illuminates or
the fuel level is very low, refuel as soon as
possible.
If inconsistency in engine performance or
stalling occurs due to low fuel level
conditions, refuel the vehicle as soon as
possible and add at least 10 L (2.7 US gal,
2.2 Imp gal) of fuel.
Refer to Low Fuel Warning Indication/
Warning Light on page 7-34.
NOTE
After refueling, it may require some time
for the indicator to stabilize. In addition,
the indicator may deviate while driving
on a slope or curve since the fuel moves
in the tank.
The direction of the arrow ()
indicates that the fuel -filler lid is on the
left side of the vehicle.
▼ Dashboard Illumination
When the lights are turned on with the
ignition switched ON, the brightness of
the dashboard illumination is dimmed.
However, when the light sensor detects
that the surrounding area is bright such as
when the lights are turned on in the
daytime, the dashboard illumination does
not dim.
NOTE
When the ignition is switched ON in the
early evening or at dusk, the dashboard
illumination is dimmed for several
seconds until the light sensor detects the
brightness of the surrounding area,
however, the dimming may cancel after
the brightness is detected.
When the lights are turned on, the
lights-on indicator light in the
instrument cluster turns on.
Refer to Headlights on page 4-44.
The brightness of the instrument panel and
dashboard illuminations can be adjusted
by pressing the dashboard illumination
switch while the dashbo ard illumination is
dimmed.
The brightness increases by pressing the
+ switch.
The brightness decreases by pressing
the - switch. If you press the - switch
while the instrument cluster is at
maximum dimness, a sound is activated
to notify you that the current dimmer
setting is at maximum dimness.

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 i n 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/off 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 4-200.
While driving the vehicle at a speed of
about 30 km/h (19 mph) or more, the
headlights are switc
hed 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 road s 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 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.
