2021 MAZDA MODEL CX-3 fuel

Break-In Period
No special break-in is necessary, but a few
precautions in the first 1,000 km (600
miles) may add to the performance,
economy, and life of the vehicle.
Do not race the engine.
Do not maintain one constant speed,
either slow or fast, for a long period of
time.
Do not drive constantly at full-throttle or
high engine rpm for extended periods of
time.
Avoid unnecessary hard stops.
Avoid full-throttle starts.
Saving Fuel and Protectionof the Environment
How you operate your Mazda determines
how far it will travel on a tank of fuel. Use
these suggestions to help save fuel and
reduce CO
2.
Avoid long warm-ups. Once the engine
runs smoothly, begin driving.
Avoid fast starts.
Drive at lower speeds.
Anticipate when to apply the brakes
(avoid sudden braking).
Follow the maintenance schedule (page
6-4) and have an Authorized Mazda
Dealer perform inspections and
servicing.
Use the air conditioner only when
necessary.
Slow down on rough roads.
Keep the tires properly inflated.
Do not carry unnecessary weight.
Do not rest your foot on the brake pedal
while driving.

Keep windows closed at high speeds.
Slow down when driving in crosswinds
and headwinds.
WA R N I N G
Never stop the engine when going down a
hill:

meter B can record the distance from
where the fuel tank is filled.

When trip meter A is selected, pressing the
selector again within one second will
change to trip meter B mode.

When trip meter A is selected, TRIP A
will be displayed. When trip meter B is
selected, TRIP B will be displayed.

The trip meter records the total distance
the vehicle is driven until the meter is
again reset. Return it to “0.0” by
depressing and holding the selector for one
second or more. Use this meter to measure
trip distances and to compute fuel
consumption.
NOTE
(Vehicles with type B audio)
If TRIP A is reset using the trip meter
when the function which synchronizes
(resets) the fuel economy monitor and
the trip meter (TRIP A) is on, the fuel
economy data resets in conjunction with
TRIP A.
Refer to Fuel Economy Monitor on page
4-69.
Only the trip meters record tenths of
kilometers (miles).
The trip record will be erased when:
The power supply is interrupted
(blown fuse or the battery is
disconnected).
The vehicle is driven over 9999.9 km
(mile).
▼Tachometer
The tachometer shows engine speed in
thousands of revolutions per minute (rpm).
CAUTION
Do not run the engine with the tachometer

the ignition is switched ON. We
recommend keeping the tank over 1/4 full.

Full
1/4 Full
Empty
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 Taking Action on page 7-33.
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 display indicating a quarter or less
remaining fuel has more segments to
show the remaining fuel level in greater
detail.
The direction of the arrow () indicates
that the fuel-filler lid is on the left side
of the vehicle.
▼ Dashboard Illumination
(Without auto-light control)
When the position lights are turned on
with the ignition
switched ON, the
brightness of the dashboard illumination is
dimmed.
(With auto-light control)
When the position 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 position lights are turned
on in the daytime, the dashboard
illumination does not dim.
NOTE
(With auto-light control)
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 dimmer may cancel after
the brightness is detected.
When the position lights are turned on,
the position lights i ndicator light in the
instrument cluster turns on.
Refer to Headlights on page 4-40.
The brightness of the instrument cluster
and dashboard illuminations can be

The vehicle speed preset using the cruise
control is displayed.

▼Trip Computer and INFO Switch
The following information can be selected
by pressing the INFO switch with the
ignition switched ON.
Distance-to-empty mode
Average fuel economy mode
Current fuel economy mode
Average vehicle speed
If you have any problems with your trip
computer, consult an Authorized Mazda

Distance-to-empty mode
This mode displays the approximate
distance you can travel on the remaining
fuel based on the fuel economy.

The distance-to-empty will be calculated
and displayed every second.

NOTE
Even though the distance-to-empty
display may indicate a sufficient amount
of remaining driving distance before
refueling is required, refuel as soon as
possible if the fuel level is very low or
the low fuel warning light illuminates.
The display may not change unless you
add more than approximately 9 L (2.3
US gal, 1.9 Imp gal) of fuel.
The distance-to-empty is the
approximate remaining distance the
vehicle can be driven until all the
graduation marks in the fuel gauge
(indicating the remaining fuel supply)
disappear.
If there is no past fuel economy
information such as after first
purchasing your vehicle or the
information is deleted when the battery
cables are disconnected, the actual
distance-to empty/range may differ from
the amount indicated.
Average fuel economy mode
This mode displays the average fuel
economy by calculating the total traveled
distance and the total fuel consumption
since the vehicle was purchased or the past
data was reset. The average fuel economy
is calculated and displayed every minute.

To clear the data being displayed, press the
INFO switch for more than 1.5 seconds or
longer.
After resetting the data, - - - L/100 km
(- - - mpg) is displayed for one minute
