Mazda Dealer.

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.



1. Label



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

Vent Operation

The ﬁgure indicates the air vent on the

left side of the instrument cluster. The

operation direction for the air vent on

the right side of the instrument cluster

is symmetrical with the air vent on the

left side.

Directing airﬂow

To adjust the direction of airﬂow, move

the adjustment knob.



When using the air conditioner

under humid ambient temperature

conditions, the system may blow fog

from the vents. This is not a sign of

trouble but a result of humid air

being suddenly cooled.



The air vents can be fully opened and

closed by operating the knob/dial.
