Fuel and Emission
Fuel-Filler Lid and Cap
WARNING
When removing the fuel-fi ller cap,
loosen the cap slightly and wait for any
hissing to stop, then remove it: Fuel spray is dangerous. Fuel can
burn skin and eyes and cause illness
if ingested. Fuel spray is released
when there is pressure in the fuel tank
and the fuel-fi ller cap is removed too
quickly.

Before refueling, stop the engine, and
always keep sparks and fl ames away
from the fi ller neck:
Fuel vapor is dangerous. It could be
ignited by sparks or fl ames causing
serious burns and injuries.
Additionally, use of the incorrect fuel-
fi ller cap or not using a fuel-fi ller cap
may result in a fuel leak, which could
result in serious burns or death in an
accident.
CAUTION
Always use only a genuine Mazda fuel-
fi ller cap or an approved equivalent,
available at an Authorized Mazda
Dealer. The wrong cap can result in
a serious malfunction of the fuel and
emission control systems. It may also
cause the check engine light in the
instrument cluster to illuminate.
Fuel-Filler Lid
To open, pull the remote fuel-fi ller lid
release.

Fuel and Emission
CAUTION
If the check fuel cap warning light
illuminates, the fuel-fi ller cap may not
be properly installed. If the warning
light illuminates, park your vehicle
safely off the right-of-way, remove the
fuel-fi ller cap and reinstall it correctly.
After the cap has been correctly
installed, the fuel cap warning light
may continue to illuminate until a
number of driving cycles have been
completed. A drive cycle consists of
starting the engine (after four or more
hours with the engine off ) and driving
the vehicle on city and highway roads.
Continuing to drive with the check
fuel cap warning light illuminated
could cause the check engine light to
illuminate as well.

Security System
NOTE
 y 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
Authorized Mazda Dealer.
 y Always keep a spare key in case one
is lost. If a key is lost, consult an
Authorized Mazda Dealer as soon as
possible.
 y If you lose a key, an Authorized Mazda
Dealer will reset the electronic codes of
your remaining keys and immobilizer
system. Bring all the remaining keys to
an Authorized Mazda Dealer to reset.
 Starting the vehicle with a key that has not been reset is not possible.
Operation
NOTE
 y 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 dashboard or in
the glove compartment. Move the key
to a location within the signal range,
switch the ignition off, and then restart
the engine.
 y 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 push button
start is pressed 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 Authorized
Mazda Dealer.
NOTE
 y  If the security indicator light fl ashes
continuously while you are driving,
do not shut off the engine. Go to an
Authorized Mazda Dealer 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.
 y  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
Authorized Mazda Dealer so that they
can be programmed.

Driving Tips
Rocking the Vehicle
WARNING
Do not spin the wheels at more than
56 km/h (35 mph), 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 tire could overheat and
explode. This could cause serious
injuries.
CAUTION
Too much rocking may cause engine
overheating, transaxle failure, and tire
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 tire
chains, window scraper, fl ares, a small
shovel, jumper cables, and a small bag of
sand or salt.
Ask an Authorized Mazda Dealer to check
the following:
 y  Have the proper ratio of antifreeze in the
radiator.
 Refer to Engine Coolant on page 6-29 . y  Inspect the battery and its cables. Cold
reduces battery capacity.
 y  Use an engine oil appropriate for the
lowest ambient temperatures that the
vehicle will be driven in (page 6-27 ).
 y  Inspect the ignition system for damage
and loose connections.
 y  Use washer fl uid made with antifreeze—
but do not use engine coolant antifreeze
for washer fl uid (page 6-31 ).

Interior Features
Climate Control System
Operating Tips
 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 effi 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 traffi c jam, or when you would like to
shut off outside air for quick cooling of
the interior.
 y  Use the outside air mode 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
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 Authorized Mazda Dealer.

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 hood 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 hood and start the engine.
If neither coolant nor steam is escaping:
Open the hood 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 Authorized Mazda
Dealer.
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.

Warning/Indicator Lights and Warning Sounds
Signal Warning
Electronic Brake Force
Distribution System Warning If the electronic brake force distribution control unit determines that \
some components
are operating incorrectly, the control unit may illuminate the brake system warning
light and the ABS warning light simultaneously. The problem is likely to be the
electronic brake force distribution system.WARNING
Do not drive with both the ABS warning light and brake warning light illuminated.
Have the vehicle towed to an Authorized Mazda Dealer to have the brakes
inspected as soon as possible:
Driving when the brake system warning light and ABS warning light are
illuminated simultaneously is dangerous.
