2019 MAZDA MODEL CX-30 check engine light

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).
