Before Driving Your Mazda
Fuel and Engine Exhaust Precautions
Form No. 8R09-EA-02G
Engine Exhaust (Carbon Monoxide)
Carbon Monoxide:
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.
Exhaust Gas in 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. Don’t run the engine when inside an
enclosed area.
Idling with the Windows Closed:
Exhaust gas is dangerous. When your vehicle is stopped with the windows closed and
the engine running for a long time in an open area, exhaust gas, which contains
poisonous carbon monoxide, could 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.
Snow Blocking the Exhaust Gas:
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, anyone in the cabin could be
injured or killed. Clear the snow from underneath and around your vehicle before
starting the engine.

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
can be used temporarily 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 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.

A/C switch
Push the switch to turn the air conditioner
on. The indicator light on the switch will
illuminate when the fan control dial is on.
Push the switch once again to turn the air
conditioner off.Air intake selector
This lever controls the source of air
entering the vehicle.
It is recommended that under normal
conditions the lever be kept in the outside
air position.
Outside air position ( )
Outside air is taken into the vehicle. Use
this position for normal ventilation and
heating.
Recirculated air position ( )
Outside air is shut off. Air within the
vehicle is recirculated.
This position can be used when driving on
a dusty road or in similar conditions. It
also helps to provide quicker cooling of
the interior.
NOTE
The air conditioner may not function
when the outside temperature
approaches 0
°C ( (32 ° F).
The Recirculated Air Position:
Using the position in cold or
rainy weather will cause the glass to
fog up. Your vision will be hampered,
which could lead to a serious
accident. Do not use the
position in cold or rainy weather.

In Case of an Emergency
Form No. 8R09-EA-02G
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 this happens:
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. Then turn the ignition
switch to the ON position without
starting the engine.
The radiator cooling fans will start to
cool the engine.
If neither coolant nor steam is
escaping:
Open the hood and idle the engine until
it cools. If this doesn ’t lower the
temperature, stop the engine and let it
cool.
5. Visually inspect the alternator/water pump drive belt for looseness and
breakage and all cooling hose
connections for leaks. If the belt is
broken or coolant is leaking, call an
Authorized Mazda Dealer for
assistance.
6. If the drive belt is OK, the engine is cool, and no coolant leaks are obvious,
inspect the coolant level. Carefully add
coolant as required (page 8-15).
Overheating
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.

In Case of an Emergency
Overheating
Form No. 8R09-EA-02G
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.
If the engine continues to overheat or
frequently overheats, have the cooling
system inspected. The engine could be
seriously damaged unless repairs are
made.
