Fuel and Emission
Fuel-Filler Lid and Cap
WARNING
When removing the fuel-filler 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-filler cap is removed too
quickly.
Before refueling, stop the engine, and
always keep sparks and flames away
from the filler neck: Fuel vapor is dangerous. It could be
ignited by sparks or flames causing
serious burns and injuries.
Additionally, use of the incorrect fuel-
filler cap or not using a fuel-filler 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
overfilling the fuel tank may cause
fuel overflow or leakage. Fuel overflow
and leakage could damage the vehicle
and if the fuel ignites it could cause a
fire and explosion resulting in serious
injury or death.
CAUTION
Always use only a genuine Mazda fuel-
filler 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-filler lid
release.
To close, press the fuel-filler lid until it
locks securely.

safety, obtaining a replacement key
requires some waiting time. They are
only available through an Authorized
Mazda Dealer.
 Always keep a spare key in case one
is lost. If a key is lost, consult an
Authorized Mazda Dealer as soon as
possible.
 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

if the key is placed in an area where it
is difficult 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.
 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 flashes 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
flashing, try the following:

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:
 Be cautious and allow extra distance for
braking. Avoid sudden braking and sudden
maneuvering. Do not pump the brakes. Continue to
press down on the brake pedal.
Refer to Antilock Brake System (ABS)
on page 4-62. If you get stuck, select a lower gear and
accelerate slowly. Do not spin the front
wheels.
 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.
NOTE
Use snow chains only on the front wheels.
Floor Mat
WARNING
Make sure the floor mats are hooked on
the retention pins to prevent them from
bunching up under the foot pedals: Using a floor 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 floor mats, one on top
of the other, on the driver's side: Installing two floor mats, one on top
of the other, on the driver's side is
dangerous as the retention pins can
only keep one floor mat from sliding
forward.
If using a heavy duty floor mat for
winter use always remove the original
floor mat.
Loose floor mat(s) will interfere with
the foot pedal and could result in an
accident.
When setting a floor mat, position the floor
mat so that its grommets are inserted over
the pointed end of the retention posts.

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

whether the brakes have been affected.
CAUTION
Do not drive the vehicle on flooded
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.
