Before Driving
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.

Do not continue refueling after the fuel
pump nozzle shuts off automatically:
Continuing to add fuel after the
fuel pump nozzle has shut off
automatically is dangerous because
overfi lling the fuel tank may cause
fuel overfl ow or leakage. Fuel overfl ow
and leakage could damage the vehicle
and if the fuel ignites it could cause a
fi re and explosion resulting in serious
injury or death.

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-¿ ller lid
release.
To close, press the fuel-¿ ller lid until it
locks securely.

M o d i¿ cation and Add-On
Equipment
Mazda cannot guarantee the immobilizer
and the theft-deterrent systems' operation
if the system has been modi¿ ed or if any
add-on equipment has been installed.
CAUTION
To avoid damage to the vehicle, do
not modify the system or install any

with an unrecognized key, the engine
will not start, thereby helping to prevent
vehicle theft.
If you have a problem with the
immobilizer system or the key, consult an
Authorized Mazda Dealer.
CAUTION
 


¾ Radio equipment like this is governed by
laws in the United States.
  Changes or modifi cations not expressly
approved by the party responsible
for compliance could void the user's
authority to operate the equipment.

N O T E
 


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
N O T E
 


y The engine may not start and security
indicator light may illuminate or À ash
if the key is placed in an area where it
is dif¿ 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 ignition is
switched from ON to off.
The security indicator light in the
instrument cluster À 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
À 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.
N O T E
 


y If the security indicator light À 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 À 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
Hazardous Driving
WARNING
Be extremely careful if it is necessary to
downshift on slippery surfaces:
Downshifting into lower gear
while driving on slippery surfaces is
dangerous. The sudden change in tire
speed could cause the tires to skid. This
could lead to loss of vehicle control
and an accident.

When driving on ice or in water, snow,
mud, sand, or similar hazards:
 


y Be cautious and allow extra distance for
braking.
 


y Avoid sudden braking and sudden
maneuvering.
 


y Do not pump the brakes. Continue to
press down on the brake pedal.
  Refer to Antilock Brake System (ABS)
on page 4-62 .




y If you get stuck, select a lower gear and
accelerate slowly. Do not spin the front
wheels.
 


y For more traction in starting on slippery
surfaces such as ice or packed snow,
use sand, rock salt, chains, carpeting, or
other nonslip material under the front
wheels.

N O T E
Use snow chains only on the front wheels.
Floor Mat
WARNING
Make sure the fl oor mats are hooked on
the retention pins to prevent them from
bunching up under the foot pedals:
Using a fl oor mat that is not secured is
dangerous as it will interfere with the
accelerator and brake pedal operation,
which could result in an accident.

Do not install two fl oor mats, one on top
of the other, on the driver's side:
Installing two fl oor mats, one on top
of the other, on the driver's side is
dangerous as the retention pins can
only keep one fl oor mat from sliding
forward.
If using a heavy duty fl oor mat for
winter use always remove the original
fl oor mat.
Loose fl oor mat(s) will interfere with
the foot pedal and could result in an
accident.


When setting a À oor mat, position the À oor
mat so that its grommets are inserted over
the pointed end of the retention posts.

3–48
Before Driving
Driving Tips
Install the chains on the front tires only.
Do not use chains on the rear tires.
Please consult an Authorized Mazda
Dealer.
Installing the chains
1. If your vehicle is equipped with wheel
covers remove them, otherwise the
chain bands will scratch them.
2. Secure the chains on the front tires as
tightly as possible.
Always follow the chain manufacturer's
instructions.
3. Retighten the chains after driving
1/2—1 km (1/4—1/2 mile).

Driving In Flooded Area
WARNING
Dry off brakes that have become
wet by driving slowly, releasing the
accelerator pedal and lightly applying
the brakes several times until the brake
performance returns to normal:
Driving with wet brakes is dangerous.
Increased stopping distance or the
vehicle pulling to one side when
braking could result in a serious
accident. Light braking will indicate
whether the brakes have been aff ected.

CAUTION
Do not drive the vehicle on fl ooded
roads as it could cause short circuiting
of electrical/electronic parts, or
engine damage or stalling from
water absorption. If the vehicle has
been immersed in water, consult an
Authorized Mazda Dealer.
