▼Engine Coolant Temperature Gauge
Displays the engine coolant temperature.
The white range of the gauge indicates
that the engine coolant temperature is low,
and the red range of the gauge indicates
that the engine coolant temperature is high
and overheating.

CAUTION
If the engine coolant temperature gauge
needle (white) flashes, there is a possibility
of overheating. Drive slowly to reduce
engine load until you can
find a safe place
to stop the vehicle and wait for the engine
to cool down.
Refer to Overheating on page 7-20.
NOTE
(SKYACTIV-G 2.5T)
If the engine coolant temperature is high
or the engine is hot, the engine output
may be limited.
The temperature unit (Centigrade/
Fahrenheit) of the engine coolant gauge
display changes in conjunction with the
temperature unit of the outside
temperature display.
Refer to the Settings section in the
Mazda Connect Owner's Manual.
▼ Fuel Gauge
The fuel gauge shows approximately how
much fuel is remaining in the tank when
the ignition is switched ON. We
recommend keeping the tank over 1/4 full.

Full
1/4 Full
Empty
If the low fuel w
arning light illuminates or
the fuel level is very low, refuel as soon as
possible.
If inconsistency in e ngine 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 7-35.
NOTE
After refueling, it may require some time
for the indicator to st abilize. In addition,
the indicator may deviate while driving
on a slope or curve since the fuel moves
in the tank.

▼Outside Temperature Display
When the ignition is switched ON, the
outside temperature is displayed.

NOTE
Under the following conditions, the
outside temperature display may differ
from the actual outside temperature
depending on the surroundings and
vehicle conditions:
Significantly cold or hot temperatures.
Sudden changes in outside
temperature.
The vehicle is parked.
The vehicle is driven at low speeds.
Changing the Temperature Unit of the
Outside Temperature Display
The outside temperature unit can be
switched between Celsius and Fahrenheit.
Settings can be changed by operating the
center display screen.
Refer to the Settings section in the Mazda
Connect Owner's Manual.
NOTE
When the temperature unit indicated in the
outside temperature display is changed,
the temperature unit indicated in the
engine coolant gauge display changes in
conjunction with it.

The following informa
tion can be selected

ignition switched ON.
Distance-to-empty mode
Average fuel economy mode
Current fuel economy mode
Compass mode
If you have any prob lems with your trip
computer, consult an Authorized Mazda
Dealer.
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.

Diesel Particulate Filter(SKYACTIV-D 2.2)
The diesel particulate filter collects and
removes most of the particulate matter
(PM) in the exhaust gas of a diesel engine.
PM collected by the diesel particulate
filter is cleared during normal driving,
however, PM may not be removed and the
diesel particulate filter indicator light may
illuminate under the following conditions:
If the vehicle is driven at 15 km/h (9
mph) or less continuously.
If the vehicle is repeatedly driven for a
short period of time (10 minute or less)
or driven while the engine is cold.
If the vehicle is idled for a long time.
When “DPF Clogged” is indicated
The particulate matter (PM) cannot be
removed automatically and the amount of
collected PM reaches a specified amount.
After the engine has sufficiently warmed
up (engine coolant temperature of 80 °C
(176 °F) or more), depress the accelerator
pedal and drive the vehicle at a speed of
20 km/h (12 mph) or more for about 15 to
20 minutes to eliminate the PM.
When “DPF malfunction” is indicated
Contact an Authorized Mazda Dealer.
CAUTION
If the vehicle continues to be driven with
“DPF Clogged” indicated in the display, the
particulate matter (PM) increases and the
indication may change to “DPF
malfunction”. If the indication changes to
“DPF malfunction”, have the vehicle
inspected immediately at an Authorized
Mazda Dealer. If the vehicle is not
inspected and continues to be driven, the
engine may malfunction.
NOTE
When “DPF malfunction” is indicated
in the display, the engine output is
restricted to protect the diesel
particulate filter.
The engine sound and exhaust gas smell
may change when PM is being removed
while driving.

*1 Top up with new diesel exhaust fluid in the urea tank once a year.*2 Check the total driving mil eage for the last three years.
If 19,200 km (12,000 miles) or mo re, top up with new diesel exhaust fluid in the urea tank.
If less than 19,200 km (12,000 mile s), replace diesel exhaust fluid in the urea tank.
*3 Replace when glow indicator light is continuously ON. Authoriz ed Mazda dealer can replace all the glow
plugs without charge if indicator light comes ON earlier than 240,000 km (150,000 miles).
*4 The engine oil and filter must b e changed at least once a year or within 12,000 km (7,500 miles) since last
engine oil and filter change. Re set the engine oil data whenever replacing the engine oil regardless of the
message/wrench indicator light display.
*5 Use of FL-22 is recommended when replacing engine coolant. Using engine coolant other than FL-22 may
cause serious damage to the engine and cooling system.
*6 According to state/provincial and federal regulations, failure to perform maintenance on these items will not
void your emissions warranties. H owever, Mazda recommends that all maintenance services be performed at
the recommended time or mileage/kilometer period to ensure long -term reliability.
*7 Check the tire repair fluid expiration date every year when performing the periodic maintenance. Replace the
tire repair fluid bottle with ne w one before the expiration dat e.
