Before Driving Your Mazda
Fuel and Engine Exhaust Precautions
Form No. 8R65-EA-03C
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,
particularly the tail pipe, 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.

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.

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.
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.
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
8-12).
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.
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.

In Case of an Emergency
Overheating
Form No. 8R65-EA-03C
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.

7. Start the engine of the booster vehicle
and run it a few minutes. Then start the
engine of the other vehicle.
8. When finished, carefully disconnect
the cables in the reverse order
described in Step 6.You can’t start a vehicle with an automatic
transmission by pushing it.
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 Moving
Par ts:
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. Never connect a
jumper cable to or near any part that
moves.
NOTE
Verify that the engine cover is securely
installed.
WARNINGPush-Starting
Towing a Vehicle to Start It:
Towing a vehicle to start it is
dangerous. The vehicle being towed
could surge forward when its engine
starts, causing the two vehicles to
collide. The occupants could be
injured. Never tow a vehicle to start it.
You shouldn’t push-start a vehicle that
has a manual transmission. It can
damage the emission control system.
