3 –24 Before Driving
Fuel and Emission Engine Exhaust (Carbon monoxide)
WARNINGDo 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.

Start/Stop Engine
Turning the Engine Off WARNINGDo not stop the engine while the vehicle
is moving:
Stopping the engine while the vehicle
is moving for any reason other than in
an emergency is dangerous. Stopping
the engine while the vehicle is moving
will result in reduced braking ability
due to the loss of power braking, which
could cause an accident and serious
injury.
1. Stop the vehicle completely.
2. (Manual transmission)
Shift into neutral and set the parking
brake.
(Automatic transmission)
Shift the selector lever to the P position
and set the parking brake.
3. Press the push button start to turn off
the engine. The ignition position is off.
CAUTION When leaving the vehicle, make sure
the push button start is off. NOTE 
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. 
When the push button start is pressed
from ON to ACC or OFF, the KEY
indicator light (green) may flash 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 6-38 . 
(Automatic transmission)
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.

Climate Control System
Operating Tips 
Operate the climate control system with
the engine running. 
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. 
Clear all obstructions such as leaves,
snow and ice from the hood and the air
inlet in the cowl grille to improve the
system efficiency. 
Use the climate control system to defog
the windows and dehumidify the air. 
The recirculate mode should be used
when driving through tunnels or while in
a traffic jam, or when you would like to
shut off outside air for quick cooling of
the interior. 
Use the outside air position for
ventilation or windshield defrosting. 
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. 
Run the air conditioner about 10 minutes
at least once a month to keep internal
parts lubricated. 
Have the air conditioner checked before
the weather gets hot. Lack of refrigerant
may make the air conditioner less
efficient.
The refrigerant specifications are
indicated on a label attached to the
inside of the engine compartment. Check
the label before refilling 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. Label

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.
