2023 MAZDA CX3 cooling

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.Fuel-Filler Lid and Cap
▼Fuel-Filler Lid and Cap
WARNING
When removing the fuel-filler cap,
loosen the cap slightly and wait for
any hissing to stop, then remove it:
Fuel spray is dangerous. Fuel can burn
skin and eyes and cause illness if
ingested. Fuel spray is released when
there is pressure in the fuel tank and
the fuel-filler cap is removed too
quickly.
Before refueling, stop the engine, and
always keep sparks and flames away
from the filler neck:
Fuel vapor is dangerous. It could be
ignited by sparks or flames causing
serious burns and injuries.
Additionally, use of the incorrect
fuel-filler cap or not using a fuel-filler
cap may result in a fuel leak, which
could result in serious burns or death
in an accident.
Do not continue refueling after the
fuel pump nozzle shuts
off
automatically:
Continuing to add fuel after the fuel
pump nozzle has shut off automatically
is dangerous because overfilling the
fuel tank may cause fuel overflow or
leakage. Fuel overflow and leakage
could damage the vehicle and if the
fuel ignites it could cause a fire and
explosion resulting in serious injury or
death.

Turning the Engine Off
▼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. 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 6-29.
A message is indicated in the display
of the instrument cluster.
Refer to KEY Warning Indication/
Warning Light (Red) on page 7-29.
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 engine is running or
the vehicle is being driven will turn the
engine off immediately. The ignition
switches to ACC.

continue to operate even if the
brake is released (except when
driving in the R or M position
second gear fixed mode).
2. The engine restarts automatically when the accelerator pedal is
depressed with the selector lever in
the D/M position (not in second
gear fixed mode).
3. If the selector lever is in the N or P position, the engine does not
restart when the brake pedal is
released. The engine restarts when
the brake pedal is depressed again
or the selector lever is shifted to the
D, M (not in second gear fixed
mode) or the R position. (For the
purposes of safety, always keep the
brake pedal depressed when
shifting the selector lever while
engine idling is stopped.)
Engine idle stopping and restarting
while driving (With M Hybrid)
(When not using MRCC with Stop &
Go function/TJA)
1. Engine idling stops when the
vehicle speed is about 20 km/h (12
mph) or slower after depressing the
brake pedal while driving the
vehicle (in D position).
2. The engine restarts automatically after releasing the brake pedal with
the selector lever in the D position.
(When using MRCC with Stop & Go
function/TJA)
1. Engine idling stops when the
vehicle has decelerated to about 20
km/h (12 mph) or slower while in
headway control using the MRCC
with Stop & Go function/TJA.
2. If it is necessary to accelerate while in headway control using the MRCC
with Stop & Go function/TJA, the
engine restarts automatically.

Operating Tips
▼Operating Tips
Operate the climate control system
with the engine running.
To prevent the battery from being
discharged, do not leave the fan
control switch 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 serious
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 conditioner
maintenance.
For details, consult an Authorized
Mazda Dealer.

Air intake selector switch
This switch controls the source of air
entering the vehicle.

Outside or recirculated air positions
can be selected. Press the switch to
select outside/recirculated air
positions.
Recirculated air position (indicator
light illuminated)
Outside air is shut off. Air within the
vehicle is recirculated. Use this
position when going through tunnels,

exhaust areas), or when quick cooling
is desired.
Outside air position (indicator light
turned off)
Outside air is allowed to enter the
cabin. Use this position for ventilation
or windshield defrosting.
WARNING
Do not use the position (indicator
light turns on) in cold or rainy
weather:
Using the
position (indicator light
turns on) in cold or rainy weather is
dangerous as it will cause the windows
to fog up. Your vision will be
hampered, which could lead to a
serious accident.
NOTE
The recirculated air position is the
default position whenever the

about 73°F (23 ℃), the climate
control system may automatically
select the recirculated air position to
improve the efficiency of the climate
control system.
