Security System
NOTE
  The keys carry a unique electronic
code. For this reason, and to assure
your safety, obtaining a replacement
key requires some waiting time.
They are only available through an
Authorised Mazda Repairer.
  Always keep a spare key in case one
is lost. If a key is lost, consult an
Authorised Mazda Repairer as soon
as possible.
  If you lose a key, an Authorised
Mazda Repairer will reset the
electronic codes of your remaining
keys and immobilizer system.
Bring all the remaining keys to an
Authorised Mazda Repairer to reset.
 Starting the vehicle with a key that
has not been reset is not possible.
Operation
NOTE
  The engine may not start and security
indicator light may illuminate or
fl ash if the key is placed in an area
where it is diffi cult for the system
to detect the signal, such as on the
instrument panel or in the glove
compartment. Move the key to a
location within the signal range,
switch the ignition off, and then
restart the engine.
  Signals from a TV or radio station,
or from a transceiver or mobile
telephone could interfere with your
immobilizer system. If you are using
the proper key and the engine fails
to start, check the security indicator
light.
Arming
The system is armed when the ignition is
switched from ON to off.
The security indicator light in the
instrument cluster fl ashes every 2 seconds
until the system is disarmed.
Disarming
The system is disarmed when the
ignition is switched ON with the correct
programmed key. The security indicator
light illuminates for about 3 seconds and
then turns off. If the engine does not start
with the correct key, and the security
indicator light remains illuminated or
fl ashing, try the following:
Make sure the key is within the
operational range for signal transmission.
Switch the ignition off, and then restart
the engine. If the engine does not start
after 3 or more tries, contact an Authorised
Mazda Repairer.
NOTE
  If the security indicator light fl ashes
continuously while you are driving,
do not shut off the engine. Go to an
Authorised Mazda Repairer and have
it checked. If the engine is shut off
while the indicator light is fl ashing,
you will not be able to restart it.
  Because the electronic codes are
reset when the immobilizer system
is repaired, the keys are needed.
Make sure to bring all the keys to an
Authorised Mazda Repairer so that
they can be programmed.

Driving Tips
Rocking the Vehicle
WARNING
Do not spin the wheels at high speed,
and do not allow anyone to stand
behind a wheel when pushing the
vehicle:
When the vehicle is stuck, spinning
the wheels at high speed is dangerous.
The spinning tyre could overheat and
explode. This could cause serious
injuries.
CAUTION
Too much rocking may cause engine
overheating, transaxle failure, and tyre
damage.
If you must rock the vehicle to free it from
snow, sand or mud, depress the accelerator
slightly and slowly move the shift lever
from 1 (D) to R.
Winter Driving
Carry emergency gear, including tyre
chains, window scraper, fl ares, a small
shovel, jumper leads, and a small bag of
sand or salt.
Ask an expert repairer, we recommend an
Authorised Mazda Repairer to check the
following:
 


 Have the proper ratio of antifreeze in the
radiator.
  Refer to Engine Coolant on page 6-30 .



 Inspect the battery and its leads. Cold
reduces battery capacity.
 


 Use an engine oil appropriate for the
lowest ambient temperatures that the
vehicle will be driven in (page 6-23 ).
 


 Inspect the ignition system for damage
and loose connections.
 


 Use washer fl uid made with antifreeze—
but do not use engine coolant antifreeze
for washer fl uid (page 6-34 ).
NOTE

 Do not use the parking brake in
freezing weather as it may freeze.
Instead, shift to P with an automatic
transaxle and to 1 or R with a manual
transaxle. Block the rear wheels.
  Remove snow before driving. Snow
left on the windscreen is dangerous
as it could obstruct vision.
  Do not apply excessive force to a
window scraper when removing ice
or frozen snow on the mirror glass
and windscreen.

Interior Features
Air-Conditioning System
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.

If Trouble Arises
Overheating
Overheating
If the High engine coolant temperature
warning light illuminates, the vehicle loses
power, or you hear a loud knocking or
pinging noise, the engine is probably too
hot.
WARNING
Switch the ignition to off and
make sure the fan is not running
before attempting to work near the
cooling fan:
Working near the cooling fan when it
is running is dangerous. The fan could
continue running indefi nitely even if
the engine has stopped and the engine
compartment temperature is high. You
could be hit by the fan and seriously
injured.
Do not remove either
cooling system cap when the engine
and radiator are hot:
When the engine and radiator are hot,
scalding coolant and steam may shoot
out under pressure and cause serious
injury.
Open the bonnet ONLY after steam is
no longer escaping from the engine:
Steam from an overheated engine is
dangerous. The escaping steam could
seriously burn you.
If the High engine coolant temperature
warning light illuminates:
1. Drive safely to the side of the road and
park off the right-of-way.
2. Put a vehicle with an automatic
transaxle in park (P), a manual
transaxle in neutral.
3. Apply the parking brake.
4. Turn off the air conditioner.
5. Check whether coolant or steam is
escaping from the engine compartment.
If steam is coming from the engine
compartment:
Do not go near the front of the vehicle.
Stop the engine.
Wait until the steam dissipates, then
open the bonnet and start the engine.
If neither coolant nor steam is
escaping:
Open the bonnet and idle the engine
until it cools.
CAUTION
If the cooling fan does not operate
while the engine is running, the engine
temperature will increase. Stop the
engine and call an expert repairer,
we recommend an Authorised Mazda
Repairer.
6. Make sure the cooling fan is operating,
then turn off the engine after the
temperature has decreased.
7. When cool, check the coolant level.
If it is low, look for coolant leaks from
the radiator and hoses.
