Interior Features
Climate Control System
O p e r a t i n g T i p s
 












y Operate the climate control system with
the engine running.
 


y 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.
 


y Clear all obstructions such as leaves,
snow and ice from the hood and the air
inlet in the cowl grille to improve the
system ef¿ ciency.




y Use the climate control system to defog
the windows and dehumidify the air.
 


y The recirculate mode should be used
when driving through tunnels or while in
a traf¿ c jam, or when you would like to
shut off outside air for quick cooling of
the interior.
 


y Use the outside air position for
ventilation or windshield defrosting.
 


y 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.

 


y Run the air conditioner about 10 minutes
at least once a month to keep internal
parts lubricated.
 


y Have the air conditioner checked before
the weather gets hot. Lack of refrigerant
may make the air conditioner less
ef¿ cient.

 The refrigerant speci¿ cations are
indicated on a label attached to the
inside of the engine compartment. Check
the label before re¿ lling the refrigerant.
If the wrong type of refrigerant is used,
it could result in a serious malfunction
of the air conditioner.
  For details, consult an Authorized
Mazda Dealer.

I : Inspect: Inspect and clean, repair, adjust, ¿ ll up, or replace if necessary.
T : Tighten
Remarks:
*1 The engine oil and ¿ lter must be changed at least once a year or within 12,000 km (7,500 miles) since last
engine oil and ¿ lter change. The system must be reset whenever replacing the engine oil regardless of the
message/wrench indicator light display.
*2 Use of FL-22 is recommended when replacing engine coolant. Using engine coolant other than FL-22 may
cause serious damage to the engine and cooling system.
*3 According to state/provincial and federal regulations, failure to perform maintenance on these items will not
void your emissions warranties. However, Mazda recommends that all maintenance services be performed at the
recommended time or mileage/kilometer period to ensure long-term reliability.
*4 The Tire Pressure Monitoring System (TPMS) initialization must be performed so that the system operates
normally (if equipped).
*5 If this component has been submerged in water, the oil should be replaced.

If Trouble Arises
Overheating
O v e r h e a t i n g
If the temperature gauge indicates
overheating or the high engine coolant
temperature warning light turns on, the
vehicle loses power, or you hear a loud
knocking or pinging noise, the engine is
probably too hot.
WARNING
Pull over to a safe location, then
switch the ignition off and make sure
the fan is not running before attempting
to work near the cooling fan:
Working near the cooling fan when it
is running is dangerous. The fan could
continue running indefi nitely even if
the engine has stopped and the engine
compartment temperature is high. You
could be hit by the fan and seriously
injured.

Do not remove either cooling
system cap when the engine and
radiator are hot:
When the engine and radiator are hot,
scalding coolant and steam may shoot
out under pressure and cause serious
injury.

Open the hood ONLY after steam is no
longer escaping from the engine:
Steam from an overheated engine is
dangerous. The escaping steam could
seriously burn you.

If the temperature gauge indicates
overheating or the high engine coolant
temperature warning light turns on:


1. Drive safely to the side of the road and
park off the right-of-way.
2. Shift into park (P).
3. Apply the parking brake.
4. Turn off the air conditioner.
5. Check whether coolant or steam is
escaping from the engine compartment.

If steam is coming from the engine
compartment:
Do not go near the front of the vehicle.
Stop the engine.
Wait until the steam dissipates, then
open the hood and start the engine.

If neither coolant nor steam is
escaping:
Open the hood and idle the engine until
it cools.
CAUTION
If the cooling fan does not operate
while the engine is running, the engine
temperature will increase. Stop the
engine and call an Authorized Mazda
Dealer.

6. Make sure the cooling fan is operating,
then turn off the engine after the
temperature has decreased.
7. When cool, check the coolant level.
If it is low, look for coolant leaks from
the radiator and hoses.
