cooling MAZDA MODEL MX-5 2020 Owners Manual (in English)

▼Engine Exhaust (Carbon monoxide)
WARNING
Do not drive your vehicle if you smell exhaust gas inside the vehicle:
Engine exhaust gas is dangerous. This gas contains carbon monoxide (CO), which is colorless,
odorless, and poisonous. When inhaled, it can cause loss of consciousness and death. If you
smell exhaust gas inside the vehicle, keep al l windows fully open and contact an Authorized
Mazda Dealer immediately.
Do not run the engine when inside an enclosed area:
Running the engine inside an enclosed area, such as a garage, is dangerous. Exhaust gas,
which contains poisonous carbon monoxide , could easily enter the cabin. Loss of
consciousness or even death could occur.
Open the windows or adjust the heating or cooling system to draw fresh air when idling the
engine:
Exhaust gas is dangerous. When the vehicle is stopped with the windows closed and the
engine running for a long time even in an open area, exhaust gas, which contains poisonous
carbon monoxide, could enter the cabin. Loss of consciousness or even death could occur.
Clear snow from underneath and around your vehicle, particularly the tail pipe, before
starting the engine:
Running the engine when a vehicle is stopped in deep snow is dangerous. The exhaust pipe
could be blocked by the snow, allowing exhaust gas to enter the cabin. Because exhaust gas
contains poisonous carbon monoxide, it could cause loss of consciousness or even death to
occupants in the cabin.

Turning the Engine Off
WARNING
Do not stop the engine while the vehicle is
moving:
Stopping the engine while the vehicle is
moving for any reason other than in an
emergency is dangerous. Stopping the
engine while the vehicle is moving will
result in reduced braking ability due to the
loss of power braking, which could cause
an accident and serious injury.
1. Stop the vehicle completely.
2.(Manual transmission)
Shift into neutral and set the parking
brake.
(Automatic transmission)
Shift the selector lever to the P
position and set the parking brake.
3. Press the push button start to turn off
the engine. The ignition position is off.
CAUTION
When leaving the vehicle, make sure the
push button start is off.
NOTE
The cooling fan in the engine
compartment could turn on for a few
minutes after the ignition is switched
from ON to OFF, whether or not the A/C
is on or off, to cool the engine
compartment quickly.
If the system detects that the remaining
battery power of the key is low when the
ignition is switched from ON to ACC or
OFF, the following is indicated.
Replace with a new battery before the
key becomes unusable.
Refer to Key Battery Replacement on
page 6-34.
(Vehicle equipped with Type A
instrument cluster)
A message is indicated in the display of
the instrument cluster.
(Vehicle equipped with Type B
instrument cluster)
The KEY indicator li ght (green) flashes
for approximately 30 seconds.
Refer to Warning/Indicator Lights on
page 4-27.
(Automatic transmission)
If the engine is turned off while the
selector lever is in a position other than
P, the ignition switches to ACC.
▼Emergency Engine Stop
Continuously pressing the push button
start or quickly pressing it any number of
times while the engi ne is running or the
vehicle is being driven will turn the engine

Operating Tips
Operate the climate control system with
the engine running.
To prevent the battery from being
discharged, do not leave the fan control
dial on for a long period of time with the
ignition switched ON when the engine is
not running.
Clear all obstructions such as leaves,
snow and ice from the hood and the air
inlet in the cowl grille to improve the
system efficiency.
Use the climate control system to defog
the windows and dehumidify the air.
The recirculate mode should be used
when driving through tunnels or while
in a traffic jam, or when you would like
to shut off outside air for quick cooling
of the interior.
Use the outside air position for
ventilation or windshield defrosting.
If the vehicle has been parked in direct
sunlight during hot weather, open the
windows to let warm air escape, then
run the climate control system.
Run the air conditioner about 10
minutes at least once a month to keep
internal parts lubricated.
Have the air conditioner checked before
the weather gets hot . Lack of refrigerant
may make the air conditioner less
efficient.
The refrigerant specifications are
indicated on a label attached to the
inside of the engine compartment. If the
wrong type of refrigerant is used, it
could result in a ser ious malfunction of
the air conditioner. Consult a
professional, government certified
repairer for the inspection or repair
because a special device is required for
the air conditi oner maintenance.
For details, consult an Authorized
Mazda Dealer.
