cooling MAZDA MODEL CX-30 2019 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 colourless, odourless, and
poisonous. When inhaled, it can cause
loss of consciousness and death. If you
smell exhaust gas inside the vehicle,
keep all windows fully open and
contact an expert repairer (we
recommend an Authorised Mazda
Repairer) 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.

NOTE
xThe 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.
xIf 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 6-39.
A message is indicated in the display
of the instrument cluster.
Refer to KEY Warning Indication/

▼i-stop
The i-stop function automatically stops
the engine when the vehicle is stopped
at a
traffic light or stuck in
traffic, and
then restarts the engine automatically
to resume driving. The system provides
improved fuel economy, reduced
exhaust gas emissions, and eliminates
idling noise while the engine is
stopped.
Engine idle stopping and restarting

Operating Tips
▼Operating Tips
xOperate the air-conditioning system
with the engine running.
xTo prevent the battery from being
discharged, do not leave the fan
control dial/switch on for a long
period of time with the ignition
switched ON when the engine is not
running.
x(With i-stop)
The
airflow amount may decrease
slightly while the i-stop function is
operating.
xClear all obstructions such as leaves,
snow and ice from the bonnet and
the air inlet in the cowl grille to
improve the system efficiency.
xUse the air-conditioning system to
defog the windows and dehumidify
the air.
xThe 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.
xUse the outside air position for
ventilation or windscreen defrosting.
xIf the vehicle has been parked in
direct sunlight during hot weather,
open the windows to let warm air
escape, then run the air-conditioning
system.
xRun the air conditioner about 10
minutes at least once a month to
keep internal parts lubricated.
xHave 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 expert repairer
(we recommend an Authorised
Mazda Repairer).
