2017 MAZDA MX5 MIATA coolant temperature

7 –27 If Trouble Arises
Overheating
OverheatingIf the high engine coolant temperature
warning light turns on, the vehicle loses
power, or you hear a loud knocking or
pinging noise, the engine is probably too
hot.
WARNING 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.
Open the hood ONLY after steam is no
longer escaping from the engine:
Steam from an overheated engine is
dangerous. The escaping steam could
seriously burn you. If the high engine coolant temperature
warning light turns on:
1. Drive safely to the side of the road and
park off the right-of-way.
2. Put a vehicle with an automatic
transmission in park (P), a manual
transmission in neutral.
3. Apply the parking brake.
4. Turn off the air conditioner.
5. Check whether coolant or steam is
escaping from the engine compartment.

If steam is coming from the engine
compartment:
Do not go near the front of the vehicle.
Stop the engine.
Wait until the steam dissipates, then
open the hood and start the engine.

If neither coolant nor steam is
escaping:
Open the hood and idle the engine until
it cools.
CAUTION If the cooling fan does not operate
while the engine is running, the engine
temperature will increase. Stop the
engine and call an Authorized Mazda
Dealer.
6. Make sure the cooling fan is operating,
then turn off the engine after the
temperature has decreased.
7. When cool, check the coolant level.
If it is low, look for coolant leaks from
the radiator and hoses.

Warning/Indicator Lights and Warning Sounds Signal Warning
(Red)
High Engine Coolant
Temperature Warning
Indication/Warning
Light The light flashes when the engine coolant temperature is extreme ly high, and
illuminates when the engine coolant temperature increases further.
Handling Procedure
Flashing light
Drive slowly to reduce engine load until you can find a safe pla ce to stop the vehicle
and wait for the engine to cool down.
Illuminated light
This indicates the possibility of overheating. Park the vehicle in a safe place
immediately and stop the engine.
Refer to Overheating 7-27 .
CAUTION Do not drive the vehicle with the high engine coolant temperature warning light
illuminated. Otherwise, it could result in damage to the engine.
Power Steering
Malfunction Indicator
Light The light illuminates if the electric power steering has a malfunction.
If the light illuminates, stop the vehicle in a safe place and do not operate the steering
wheel. There is no problem if the light turns off after a while. Contact an Authorized
Mazda Dealer if the light illuminates continuously.
NOTE 
If the indicator light illuminates, the power steering will not operate normally. If this
happens, the steering wheel can still be operated, however, the operation may feel
heavy compared to normal, or the steering wheel could vibrate when turning. 
Repeatedly jerking the steering wheel left and right while the vehicle is stopped or
moving extremely slowly will cause the power steering system to go into protective
mode which will make the steering feel heavy, but this does not indicate a problem. If
this occurs, park the vehicle safely and wait several minutes for the system to return
to normal.
