2017 MAZDA MX5 MIATA coolant temperature

4 –22 When Driving
Instrument Cluster and Display Outside Temperature DisplayWhen 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
using the following procedure.
(Vehicles with Type B)
Settings can be changed by operating the
center display screen.
Refer to Personalization Features on page
9-9 .
(Vehicles without Type B)
1. Press the INFO switch with the ignition
switched off and continue pressing the
INFO switch for 5 seconds or longer
while switching the ignition ON. The
outside temperature display flashes.
2. Press the INFO switch to change the
outside temperature unit.
3. Press and hold the INFO switch for
3 seconds or longer while the outside
temperature display is flashing. The
outside temperature display illuminates. 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. 
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.

Owner Maintenance6. Make sure the O-ring on the dipstick is
positioned properly before reinserting
the dipstick.
7. Reinsert the dipstick fully.
Engine Coolant Inspecting Coolant Level
WARNING Do not use a match or live flame in the
engine compartment. DO NOT ADD
COOLANT WHEN THE ENGINE IS HOT:
A hot engine is dangerous. If the
engine has been running, parts of the
engine compartment can become very
hot. You could be burned. Carefully
inspect the engine coolant in the
coolant reservoir, but do not open it.
Pull over to a safe location, then
switch the ignition off and make sure
the fan is not running before attempting
to work near the cooling fan:
Working near the cooling fan when it
is running is dangerous. The fan could
continue running indefinitely even if
the engine has stopped and the engine
compartment temperature is high. You
could be hit by the fan and seriously
injured.
Do not remove either cooling
system cap when the engine and
radiator are hot:
When the engine and radiator are hot,
scalding coolant and steam may shoot
out under pressure and cause serious
injury.
NOTE
Changing the coolant should be done by
an Authorized Mazda Dealer.
MX-5_8FR4-EA-16J_Edition1.indb 29 2016/08/11 20:29:43

6 –30 Maintenance and Care
Owner Maintenance Inspect the antifreeze protection and
coolant level in the coolant reservoir at
least once a year—at the beginning of the
winter season—and before traveling where
temperatures may drop below freezing.
Inspect the condition and connections of
all cooling system and heater hoses.
Replace any that are swollen or
deteriorated.
The coolant should be at full in the
radiator and between the FULL and LOW
marks on the coolant reservoir when the
engine is cool. Coolant reservoir
Cooling fa nCooling system cap
If it is at or near LOW, add enough coolant
to the coolant reservoir to provide freezing
and corrosion protection and to bring the
level to FULL.
Securely tighten the coolant reservoir tank
cap after adding coolant. CAUTION 
Radiator coolant will damage paint.
Rinse it off quickly if spilled. 
Use only soft (demineralized) water in
the coolant mixture. Water that contains
minerals will cut down on the coolant's
effectiveness. 
Do not add only water. Always add a
proper coolant mixture. 
The engine has aluminum parts and
must be protected by an ethylene-glycol-
based coolant to prevent corrosion and
freezing. 
DO NOT USE coolants Containing
Alcohol, methanol, Borate or Silicate.
These coolants could damage the
cooling system. 
DO NOT MIX alcohol or methanol with
the coolant. This could damage the
cooling system. 
Do not use a solution that contains more
than 60% antifreeze.
This would reduce effectiveness. 
If the “FL22” mark is shown on or near
the cooling system cap, 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.
If the coolant reservoir is empty or new
coolant is required frequently, consult an
Authorized Mazda Dealer.

6 –68 Maintenance and Care
Appearance Care Plastic Part Maintenance 
When cleaning the plastic lenses of the
lights, do not use gasoline, kerosene,
rectified spirit, paint, thinner, highly
acidic detergents, or strongly alkaline
detergents. Otherwise, these chemical
agents can discolor or damage the
surfaces resulting in a significant loss
in functionality. If plastic parts become
inadvertently exposed to any of these
chemical agents, flush with water
immediately. 
If plastic parts such as the bumpers
become inadvertently exposed to
chemical agents or fluids such as
gasoline, oil, engine coolant, or battery
fluid, it could cause discoloration,
staining, or paint peeling. Wipe off any
such chemical agents or fluids using a
soft cloth immediately. 
High water temperature and high water
pressure car washers are available
depending on the type of high pressure
car washer device. If the car washer
nozzle is put too close to the vehicle or
aimed at one area for an extended period
of time, it could deform plastic parts or
damage the paint. 
Do not use wax containing compounds
(polish). Otherwise, it could result in
paint damage. 
In addition, do not use an electrical or
air tool to apply wax. Otherwise, the
frictional heat generated could result
in deformation of plastic parts or paint
damage. Interior Care WARNING Do not spray water into the vehicle
cabin:
Spraying water into the vehicle cabin is
dangerous as electrical devices such as
the audio and switches could get wet
resulting in a malfunction or vehicle
fire.
NOTE 
Do not wipe the interior using alcohol,
chlorine bleach, or organic solvents
such as thinner, benzene, and gasoline.
Otherwise, it may cause discoloration
or stains. 
Rubbing hard with a stiff brush or cloth
may cause damage.
If the vehicle interior becomes soiled
by any of the following, wipe it off
immediately using a soft cloth.
Leaving it uncleaned could cause
discoloration, stains, cracks, or peeling
of the coating, and it will make it hard to
wipe off later. 
Beverage or fragrance 
Grease or oil 
Soiling
Seat Belt Maintenance
1. Clean the soiled area by lightly dabbing
it with a soft cloth soaked in a mild
detergent (approx. 5%) diluted with
water.
2. Wipe off the remaining detergent using
a cloth soaked in clean water and
wrung out well.
3. Before retracting seat belts which have
been pulled out for cleaning, dry them
off thoroughly and make sure there is
no remaining moisture on them.
