coolant level MAZDA MODEL MX-5 MIATA RF 2020 Owners Manual

▼Engine Coolant Temperature Gauge
(Without Multi-information
Display)
Indicates engine coolant temperature.
CAUTION
If the high engine coolant temperature
warning light (red)
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 7-27.
NOTE
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 Personalization Features on
page 9-9.
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).
If the engine load increases and the
engine coolant temperature exceeds
100 °C (210 °F), the gauge indicates the
engine coolant temperature.
▼ Fuel Gauge (Without
Multi-information Display)
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 7-40.
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.

▼Engine Coolant Temperature Gauge
Displays the engine coolant temperature.
The blue gauge indicates that the engine
coolant temperature is low, and the red
gauge indicates that the engine coolant
temperature is high and overheating.
The engine coolant temperature gauge can
be switched to indicate only the high
engine coolant temperature range by
pressing the panel light control switch.
CAUTION
If the high engine coolant temperature
warning light (red) 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.

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.
▼ Outside Temperature Display
When the ignition is switched ON, the
outside temperatur
e 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
using the following procedure.
Settings can be changed by operating the
center display screen.
Refer to Personalization Features on page
9-9.
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.
▼ Distance-to-empty
This 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 will not change unless you
add more than approximately 9 L (2.3
US gal, 1.9 Imp gal) of fuel.
