Climate Control System

Operating the Climate Control
System
Operate the climate control system with
the engine running.

Clearing the Air Inlet
Clear all obstructions like leaves, snow
and ice from the hood and the air inlet in
the cowling grille to improve the system
efficiency.

Foggy 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.

Outside/Recirculated Air
Position
Use the outside air position in normal
conditions. The recirculated air position
should be used only when driving on
dusty roads or for quick cooling of the
interior.

Parking 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.

Not Using for a Long Period
Run the air conditioner about 10 minutes
at least once a month to keep internal
parts lubricated.

Check 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.
Operating Tips

Power Antenna
The antenna automatically rises when the
radio is turned on, and lowers when it is
turned off.
Antenna
• To prevent damaging the antenna,
retract it before entering a car wash
facility or passing beneath a low
overhead clearance.
• Make sure no one is near the
antenna before turning on the radio
to prevent injury or damage to the
antenna.
CAUTION
Operating Tips for Audio
System
Do Not Adjust Audio While Driving
the Vehicle:
Adjusting the audio while driving the
vehicle is dangerous as it could
distract your attention from the
vehicle operation which could lead to
a serious accident. Always adjust the
audio while the vehicle is stopped.
For the purposes of safe driving, adjust
the audio volume to a level that allows
you to hear sounds outside of the
vehicle.
NOTE
•Do not use the audio for long
periods of time while the engine is
off. Otherwise the battery could go
dead.
• If a digital cellular phone or CB
radio is used in or near the vehicle,
it could cause noise to occur from
the audio system, however, this does
not indicate that the system has
been damaged.

Flat Tire
Form No. 8T02-EA-03L
1. Park on a level surface off the right-of-way and firmly set the parking brake.
2. Put a vehicle with an automatic transmission in Park (P), a manual
transmission in Reverse (R) or 1, and
turn off the engine.
3. Turn on the hazard warning flasher.
4. Have everyone get out of the vehicle and away from the vehicle and traffic.
5. Remove the jack, tool, and spare tire (page 7-3).
6. Block the wheel diagonally opposite the flat tire. When blocking a wheel,
place a block both in front and behind
the tire.

Removing a Flat Tire
1. Loosen the lug nuts by turning them
counterclockwise one turn each, but
don ’t remove any lug nuts until the tire
has been raised off the ground.
2. Place the jack under the jacking position closest to the tire being
changed.
NOTE
Make sure the jack is well lubricated
before using it.
NOTE
When blocking a tire, use rocks or
wood blocks of sufficient size to hold
the tire in place.

Overheating
If the temperature gauge indicates
overheating, the vehicle loses power, or
you hear a loud knocking or pinging
noise, the engine is probably too hot.
If the temperature gauge indicates
overheating:1. Drive safely to the side of the road and
park off the right-of-way.
2. Put a vehicle with an automatic transmission in park (P), a manual
transmission in neutral.
Apply the parking brake.
3. Turn off the air conditioner.
4. Check whether coolant or steam is escaping from under the hood or from
the engine compartment.
If steam is coming from the engine
compartment:
Don ’t 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.
5. Make sure the cooling fan is operating, then turn off the engine after the
temperature has decreased.
Overheating
Cooling Fan and Engine
Inspection:
Inspecting the engine with the
ignition switch in the ON position is
dangerous. The cooling fan could
turn on unexpectedly even when the
engine isn ’t running. You could be
seriously injured by the fan. Turn the
ignition switch off and remove the key
from the ignition switch when you
inspect the engine.
Cooling System Cap:
When the engine and radiator are
hot, scalding coolant and steam may
shoot out under pressure and cause
serious injury. Don ’t remove the
cooling system cap when the engine
and radiator are hot.
Steam from Overheated Engine:
Steam from an overheated engine is
dangerous. The escaping steam could
seriously burn you. Open the hood
ONLY after steam is no longer
escaping from the engine.
WARNING
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.

Overheating
Form No. 8T02-EA-03L
6. When cool, check the coolant level.If it ’s low, look for coolant leaks from
the radiator and hoses.
If you find a leak or other damage,
or if coolant is still leaking:
Stop the engine and call an Authorized
Mazda Dealer.
If you find no problems, the engine is
cool, and no leaks are obvious:
Carefully add coolant as required (page
8-15).
If the engine continues to overheat or
frequently overheats, have the cooling
system inspected. The engine could be
seriously damaged unless repairs are
made. Consult an Authorized Mazda
Dealer.

Emergency Starting
If the engine fails to start, it may be
flooded (excessive fuel in the engine).
Follow this procedure:
1. Depress the accelerator all the way and hold it there.
2. Turn the ignition switch to the START position and hold it there —for up to 10
seconds. If the engine starts, release the
key and accelerator immediately
because the engine will suddenly rev
up.
3. If the engine fails to start, crank it without depressing the accelerator —
for up to 10 seconds. The battery is in the trunk.
Jump-starting is dangerous if done
incorrectly. So follow the procedure
carefully. If you feel unsure about jump-
starting, we strongly recommend that you
have a competent service technician do
the work.
Starting a Flooded EngineJump-Starting
Battery-Related Explosion:
Flames and sparks near open battery
cells are dangerous. Hydrogen gas,
produced during normal battery
operation, could ignite and cause the
battery to explode. An exploding
battery can cause serious burns and
injuries. Keep all flames, including
cigarettes, and sparks away from
open battery cells.
Frozen Battery:
Jump-starting a frozen battery is
dangerous. It may rupture or explode,
causing serious injury.
Don
’t jump-start a frozen battery .
Use only a 12 V booster system. You
can damage a 12 V starter, ignition
system, and other electrical parts
beyond repair with a 24 V power
supply (two 12 V batteries in series or
a 24 V motor generator set).
