Operating Tips
qOperating the Climate Control
System
Operate the climate control system with
the engine running.
NOTE
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.
qClearing the Air Inlet
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.
qFoggy Windows
The windows may fog up easily in humid
weather. Use the climate control system to
defog the windows.
To help defog the windows, operate the
air conditioner to dehumidify the air.
NOTE
The air conditioner may be used along with the
heater to dehumidify the air.
qParking in Direct Sunlight
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.
qNot Using for a Long Period
Run the air conditioner about 10 minutes
at least once a month to keep internal
parts lubricated.
qCheck the Refrigerant before the
Weather Gets Hot
Have the air conditioner checked before
the weather gets hot. Lack of refrigerant
may make the air conditioner less
efficient. Consult an Authorized Mazda
Dealer for refrigerant inspection.
The air conditioner is filled with
HFC134a (R134a), a refrigerant that will
not damage the ozone layer.
If the air conditioner is low on refrigerant
or has a malfunction, consult an
Authorized Mazda Dealer.
qReplacement of the Cabin Air
Filterí
Your vehicle is equipped with an air filter
for the air conditioner. It is necessary to
change the filter periodically as indicated
in scheduled maintenance (page 8-3).
Consult an Authorized Mazda Dealer for
replacement of the cabin air filter.

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 indefinitely
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 the 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 under the hood or 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 reservoir level.
If it's low, look for coolant leaks from
the radiator and hoses.

Owner Maintenance Precautions
Improper or incomplete service may result in problems. This section gives instructions only
for items that are easy to perform.
As explained in the Introduction (page 8-2), several procedures can be done only by a
qualified service technician with special tools.
Improper owner maintenance during the warranty period may affect warranty coverage.
For details, read the separate Mazda Warranty statement provided with the vehicle. If
you're unsure about any servicing or maintenance procedure, have it done by an
Authorized Mazda Dealer.
There are strict environmental laws regarding the disposal of waste oil and fluids. Please
dispose of your waste properly and with due regard to the environment.
We recommend that you entrust the oil and fluid changes of your vehicle to an Authorized
Mazda Dealer.
WARNING
Do not perform maintenance work if you lack sufficient knowledge and experience or
the proper tools and equipment to do the work. Have maintenance work done by a
qualified 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 indefinitely 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 finished 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
fire leading to an unexpected accident.

Automatic Transaxle Fluid
(ATF)
í
qInspecting Automatic Transaxle
Fluid Level (5-speed transaxle)
The automatic transaxle fluid level should
be inspected regularly. Measure it as
described below.
CAUTION
Ø Always check the automatic
transaxle fluid level according to
the following procedure. If the
procedure is not done correctly,
the automatic transaxle fluid level
cannot be measured accurately
which could lead to automatic
transaxle damage.
Ø A low fluid level can cause
transaxle slippage. Overfilling can
cause foaming, loss of fluid, and
transaxle malfunction.
Ø It is recommended to use Mazda
Genuine automatic transaxle fluid
(page 10-5).
1. Park on a level surface and set the parking brake firmly.
2. Make sure there is no ATF leakage from the ATF hose or the housing.
3. Shift the shift lever to the park position (P), start the engine and warm it up.
CAUTION
Do not shift the shift lever while the
engine is warming up. If the ATF level
is extremely low, the automatic
transaxle could be damaged. 4. While the engine is still idling, pull out
the dipstick and wipe it clean, and then
put it back.
5. Check the ATF level. If there is no ATF adhering 5 mm from the end of the
dipstick, add ATF.
CAUTION
If there is no ATF adhering to the
dipstick even after the engine has
been warmed up, do not drive the
vehicle. Otherwise, the automatic
transaxle could be damaged.
6. Shift the shift lever to each range and position, and make sure there is no
abnormality.
7. Drive the vehicle on city roads for 5 km (3.1 mile) or more.
8. Park on a level surface and set the parking brake firmly.
9. Shift the shift lever to the park position (P), check the ATF level while the
engine is idling, and make sure that the
ATF level is within the proper level. If
the ATF level is not within the proper
level, add ATF. The proper fluid level
is marked on the dipstick as follows.

qAluminum Wheel Maintenanceí
A protective coating is provided over the
aluminum wheels. Special care is needed
to protect this coating.
CAUTION
Do not use any detergent other than
mild detergent. Before using any
detergent, verify the ingredients.
Otherwise, the product could discolor
or stain the aluminum wheels. NOTE
lDo not use a wire brush or any abrasive
cleaner, polishing compound, or solvent on
aluminum wheels. They may damage the
coating.
lAlways use a sponge or soft cloth to clean
the wheels.
Rinse the wheels thoroughly with lukewarm
or cold water. Also, be sure to clean the
wheels after driving on dusty or salted
roads to help prevent corrosion.
lAvoid washing your vehicle in an automatic
car wash that uses high-speed or hard
brushes.
lIf your aluminum wheels lose luster, wax
the wheels.
(With Tire Pressure Monitoring System)
Check special requirements for Tire Pressure
Monitoring System.

detergents. Otherwise, these chemical
agents can discolor or damage the
surfaces resulting in a significant loss
in functionality. If plastic parts become
inadvertently exposed to any of these
chemical agents, flush with water
immediately.
lIf plastic parts such as the bumpers
become inadvertently exposed to
chemical agents or fluids such as
gasoline, oil, engine coolant, or battery
