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
colourless, odourless, 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 expert repairer, we recommend an Authorised Mazda Repairer 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
WARNING
Do 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 transaxle)
Shift into neutral and set the parking
brake.
(Automatic transaxle)
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

2.0)
 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 fl 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 6-43 .
 (Automatic transaxle) If the engine is turned off while the
selector lever is in a position other

Operating Tips
 












 Operate the air-conditioning 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.
 


(With i-stop)
 The airfl ow amount may decrease
slightly while the i-stop function is
operating.
 


 Clear all obstructions such as leaves,
snow and ice from the bonnet and the
air inlet in the cowl grille to improve the
system effi ciency.




 Use the air-conditioning system to defog
the windows and dehumidify the air.
 


 The recirculate mode should be used
when driving through tunnels or while in
a traffi c 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 windscreen defrosting.
 


 If the vehicle has been parked in direct
sunlight during hot weather, open the
windows to let warm air escape, then
run the air-conditioning system.
(With A/C switch)
 




 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
effi cient.

 The refrigerant specifi cations are
indicated on a label attached to the
inside of the engine compartment. Check
the label before refi 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 expert repairer,
we recommend an Authorised Mazda
Repairer.
