Engine Exhaust (Carbon Monoxide)
WARNING
Do not drive your vehicle if you smell exhaust gas inside the vehicle:Engine exhaust gas is dangerous. This gas contains carbon monoxide (CO), which is
colorless, odorless, and poisonous. When inhaled, it can cause loss of consciousness
and death. If you smell exhaust gas inside your vehicle, keep all windows fully open
and contact an Authorized Mazda Dealer immediately.
Do not run the engine when inside an enclosed area: Running the engine inside an enclosed area, such as a garage, is dangerous. Exhaust
gas, which contains poisonous carbon monoxide, could easily enter the cabin. Loss
of consciousness or even death could occur.
Open the windows or adjust the heating or cooling system to draw fresh air when
idling the engine: Exhaust gas is dangerous. When your vehicle is stopped with the windows closed
and the engine running for a long time even in an open area, exhaust gas, which
contains poisonous carbon monoxide, could enter the cabin. Loss of consciousness or
even death could occur.
Clear snow from underneath and around your vehicle, particularly the tail pipe,
before starting the engine: Running the engine when a vehicle is stopped in deep snow is dangerous. The
exhaust pipe could be blocked by the snow, allowing exhaust gas to enter the cabin.
Because exhaust gas contains poisonous carbon monoxide, it could cause loss of
consciousness or even death to occupants in the cabin.

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 switch in the
ON position when the engine is not running.
qClearing the Air Inlet
Clear all obstructions like 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.
qOutside/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.
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
If 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.

maintain maximum comfort.
lThe air to the floor is warmer than air to
the face (except when the temperature
control dial is set at the extreme hot or cold
position).
lIn the,,orposition, the air
conditioner is automatically turned on
(however, the indicator light does not
illuminate) and the outside air mode is

maximum comfort.
CAUTION
When using the air conditioner while
driving up long hills or in heavy
traffic, closely monitor the
temperature gauge (page 5-34).
The air conditioner may cause engine
overheating. If the gauge indicates
overheating, turn the air conditioner
off (page 7-14).
NOTE
lWhen maximum cooling is desired, set the
temperature control dial to the extreme cold
position and set the air intake selector to
the recirculated air mode, then set the fan
control dial to position 4.
lIf warmer air is desired at floor level, set
the mode selector dial at the

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.
WARNING
Turn off the ignition switch 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 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
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:
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.
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'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.
Except L3 turbocharger engine

If you find no problems, the engine is
cool, and no leaks are obvious:
Carefully add coolant as required (page
8-21).
CAUTION
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.

Keep all flames, including cigarettes, and sparks away from open battery cells:
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.
Do not jump-start a frozen battery or one with a low fluid level: Jump-starting a frozen battery or one with a low fluid level is dangerous. It may
rupture or explode, causing serious injury.
Connect the negative cable to a good ground point away from the battery: Connecting the end of the second jumper cable to the negative (
) terminal of the
discharged battery is dangerous.
A spark could cause the gas around the battery to explode and injure someone.
Route the jumper cables away from parts that will be moving: Connecting a jumper cable near or to moving parts (cooling fans, belts) is dangerous.
The cable could get caught when the engine starts and cause serious injury.
CAUTION
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).
