Interior Features
Climate Control System
Operating Tips
 y Operate the climate control system with
the engine running.
 y  To prevent the battery from being
discharged, do not leave the fan control
dial 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 effi 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 traffi c jam, or when you would like to
shut off outside air for quick cooling of
the interior.
 y  Use the outside air mode 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
effi cient.
 The refrigerant specifi cations are
indicated on a label attached to the
inside of the engine compartment. Check
the label before refi 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.

Maintenance and Care
Owner Maintenance
WARNING
Do not perform maintenance work if you lack suffi cient knowledge and experience
or the proper tools and equipment to do the work. Have maintenance work done by a
qualifi ed technician:
Performing maintenance work on a vehicle is dangerous if not done properly. You can be
seriously injured while performing some maintenance procedures.

If you must run the engine while working under the hood, make certain that you
remove all jewelry (especially rings, bracelets, watches, and necklaces) and all
neckties, scarves, and similar loose clothing before getting near the engine or cooling
fan which may turn on unexpectedly: Working under the hood with the engine running is dangerous. It becomes even more
dangerous when you wear jewelry or loose clothing.
Either can become entangled in moving parts and result in injury.

Switch the ignition to 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 leave items in the engine compartment: After you have fi nished checking or doing servicing in the engine compartment, do not
forget and leave items such as tools or rags in the engine compartment.
Tools or other items left in the engine compartment could cause engine damage or a fi re
leading to an unexpected accident.

If Trouble Arises
Overheating
Overheating
If the High engine coolant temperature
warning light illuminates, the vehicle loses
power, or you hear a loud knocking or
pinging noise, the engine is probably too
hot.
WARNING
Switch the ignition to 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 High engine coolant temperature
warning light illuminates:
1. Drive safely to the side of the road and park off the right-of-way.
2. Put a vehicle with an automatic transaxle in park (P), a manual
transaxle in neutral.
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.
