engine MAZDA MODEL 6 2020 (in English) Service Manual

▼Engine Coolant Temperature Gauge
Displays the engine coolant temperature.
The blue 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 is in the red range, there is the
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, SKYACTIV-D 2.2)
If the engine coolant temperature is high
or the engine is hot, the engine output
may be limited.
During normal driving, the engine
coolant temperature stabilizes at 100 °C
(210 °F) or less, and the gauge indicates
a range lower than 100 °C (210 °F).
▼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 warni
ng 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 7-35.
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.

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

NOTE
Under the following conditions, the

from the actual outside temperature
depending on the surroundings and
vehicle conditions:
Significantly cold or hot temperatures.
Sudden changes in outside
temperature.

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 Other Equ ipment/Functions on
page 9-15.
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.
