Before Driving Your Mazda
Fuel and Engine Exhaust Precautions
Form No. 8Q47-EA-01F
Engine Exhaust (Carbon Monoxide)
Carbon Monoxide:
Engine exhaust 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
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 optional air conditioner is filled with
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.

Replacement of the Cabin Air
Filter
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.

Air intake selector switch
Outside or recirculated air positions can
be selected. Press the switch to select
outside/recirculated air positions.
Recirculated air position ( )
Use this position when going through
tunnels, driving in congested traffic (high
engine exhaust areas) or when quick
cooling is desired.
Outside air position ( )
Use this position for normal conditions
and defogging.AMB (Ambient Temperature) switch
Press the AMB switch. The outside
temperature will be displayed and the
indicator light will illuminate. Press the
switch again, the outside temperature will
disappear and the indicator light will go
off.
NOTE
•Although air conditioning and
defogging ability is reduced, the
A/C ECON function is designed to
economize use of the air
conditioning system.
•The air conditioner may not
function when the outside
temperature approaches 0 °C
(32 °F). (Indicator remains on even
when system is off.) 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.
NOTE
When the air conditioner is operating
and the temperature control is
operated, the display will change to air
conditioner setting temperature.

Form No. 8Q47-EA-01F
Overheating
If the temperature gauge indicates
overheating, you experience power loss,
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. Shift into park (P) .
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. Check the coolant level.
If it’s low, look for leaks in the radiator
hoses and connections, heater hoses
and connections, radiator, and water
pump.
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 8-12).
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. 8Q47-EA-01F
Cooling System Caps:
When the engine and radiator are
hot, scalding coolant and steam may
shoot out under pressure and cause
serious injury. Don’t remove either
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.

In Case of an Emergency
Emergency Starting
Form No. 8Q47-EA-01F
1. Make sure the booster battery is 12 V
and that its negative terminal is
grounded.
2. If the booster battery is in another
vehicle, don’t allow the vehicles to
touch. Turn off the engine of the
vehicle with the booster battery and all
unnecessary electrical loads in both
vehicles.
3. Connect the jumper cables in the exact
sequence as in the illustration.
•Connect one end of a cable to the
positive terminal on the discharged
battery (1).
•Attach the other end to the positive
terminal on the booster battery (2).
•Connect one end of the other cable
to the negative terminal of the
booster battery (3).
•Connect the other end to a solid,
stationary, exposed metallic point
(for example, the engine hanger)
away from the discharged battery
(4).4. Start the engine of the booster vehicle
and run it a few minutes. Then start the
engine of the other vehicle.
5. When finished, carefully disconnect
the cables in the reverse order
described in Step 3.

battery
Connecting to Negative Terminal:
Connecting the end of the second
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. Connect the cable to a point
away from the battery.
Connecting Jumper Cable to a
Moving Part:
Connecting a jumper cable near or to
a moving parts (cooling fans, belts) is
dangerous. The cable could get
caught when the engine starts and
cause serious injury. Never connect a
jumper cable to or near any part that
moves.
