Before Driving
Fuel and Emission
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 the 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 the 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.

y The cooling fan in the engine
compartment could turn on for a few
minutes after the ignition is switched
from ON to OFF, whether or not the
A/C is on or off, to cool the engine
compartment quickly.
 


y When the push button start is pressed
from ON to ACC or OFF, the KEY
indicator light (green) may À ash for
approximately 30 seconds indicating
that the remaining battery power of the
key is low.
  Replace with a new battery before the
key becomes unusable.
  Refer to Key Battery Replacement on
page 6-39 .
 


y If the engine is turned off while the
selector lever is in a position other than
P, the ignition switches to ACC.

Emergency Engine Stop
Continuously pressing the push button
start or quickly pressing it any number of
times while the engine is running or the
vehicle is being driven will turn the engine
off immediately. The ignition switches to
ACC.

y Operate the climate control system with
the engine running.
 


y To prevent the battery from being
discharged, do not leave the fan control
dial on for a long period of time with the
ignition switched ON when the engine is
not running.
 


y Clear all obstructions such as leaves,
snow and ice from the hood and the air
inlet in the cowl grille to improve the
system ef¿ ciency.




y Use the climate control system to defog
the windows and dehumidify the air.
 


y The recirculate mode should be used
when driving through tunnels or while in
a traf¿ c jam, or when you would like to
shut off outside air for quick cooling of
the interior.
 


y Use the outside air position for
ventilation or windshield defrosting.
 


y 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.

 


y Run the air conditioner about 10 minutes
at least once a month to keep internal
parts lubricated.
 


y Have the air conditioner checked before
the weather gets hot. Lack of refrigerant
may make the air conditioner less
ef¿ cient.

 The refrigerant speci¿ cations are
indicated on a label attached to the
inside of the engine compartment. Check
the label before re¿ lling the refrigerant.
If the wrong type of refrigerant is used,
it could result in a serious malfunction
of the air conditioner.
  For details, consult an Authorized
Mazda Dealer.

Climate Control System
Cooling (With air conditioner)
1. Set the mode selector dial to the
position.
2. Set the temperature control dial to the
cold position.
3. Set the fan control dial to the desired
speed.
4. Turn on the air conditioner by pressing
the A/C switch.
5. After cooling begins, adjust the fan
control dial and temperature control
dial as needed to maintain maximum
comfort.

CAUTION
If the air conditioner is used while
driving up long hills or in heavy
traffi c, monitor the engine coolant
temperature warning light to see if it is
illuminated or fl ashing (page 4-24 ).
The air conditioner may cause engine
overheating. If the warning light is
illuminated or fl ashing, turn the air-
conditioning off (page 7-22 ).

N O T E




y When maximum cooling is desired,
set the temperature control dial to the
extreme cold position and set the air
intake selector to the recirculated air
position, then set the fan control dial to
position 4.
 


y If warmer air is desired at À oor level,
set the mode selector dial at the

position and adjust the temperature
control dial to maintain maximum
comfort.
 


y The air to the À oor is warmer than air
to the face (except when the temperature
control dial is set at the extreme hot or
cold position).

Ventilation
1. Set the mode selector dial to the
position.
2. (Type A)
Set the air intake selector to the outside
air position.
(Type B)
Set the air intake selector to the

position.
3. Set the temperature control dial to the
desired position.
4. Set the fan control dial to the desired

Air intake selector
Outside or recirculated air positions can be
selected. Press the switch to select outside/
recirculated air positions.
Recirculated air position (indicator light
illuminated)
Outside air is shut off. Use this position
when going through tunnels, driving in
congested traf¿ c (high engine exhaust
areas) or when quick cooling is desired.
Outside air position (indicator light
turned off)
Outside air is allowed to enter the
cabin. Use this mode for ventilation or
windshield defrosting.
WARNING
Do not use the position in cold or
rainy weather:
Using the
position in cold or rainy
weather is dangerous as it will cause
the windows to fog up. Your vision will
be hampered, which could lead to a
serious accident.

Operation of Automatic Air-
Conditioning
1. Set the mode selector dial to the AUTO
position.
2. Set the air intake selector to the outside
air position (indicator light turned off).
N O T E
If the recirculated air position is used
for long periods in cold weather or high
humidity, the windshield may fog up more
easily.

3. Set the fan control dial to the AUTO
position.
4. Press the A/C switch to operate the air-
conditioning (turn indicator light on).
5. Set the temperature control dial to the
desired position.
6. To turn off the system, set the fan
control dial to the 0 position.

N O T E
 


y Setting the temperature to maximum
hot or cold will not provide the desired
temperature at a faster rate.
 


y When selecting heat, the system will
restrict airÀ ow until it has warmed to
prevent cold air from blowing out of the
vents.

cause serious damage to the engine and cooling system.
*3 According to state/provincial and federal regulations, failure to perform maintenance on these items will not
void your emissions warranties. However, Mazda recommends that all maintenance services be performed at the
recommended time or mileage/kilometer period to ensure long-term reliability.
*4 The Tire Pressure Monitoring System (TPMS) initialization must be performed so that the system operates
normally (if equipped).
*5 If the vehicle is operated primarily under any of the following conditions, replace the rear differential oil at
every 48,000 km (30,000 miles).
a) Towing a trailer or using a car-top carrier
