Luggage Compartment
Luggage compartment cover (5-door)
WARNING
Do not place anything on top of the
cover:Placing luggage or other cargo on top
of the luggage compartment cover is
dangerous. During sudden braking or
a collision, the cargo could become
a projectile that could hit and injure
someone. The vehicle has a light
weight luggage compartment cover to
keep the contents of your luggage area
out of sight; it will not retain heavy
objects that are not tied down in an
accident such as a rollover. Tie down
all heavy objects, whether luggage or
cargo, using the tie down hooks.
Make sure luggage and cargo are
secured before driving: Not securing cargo while driving is
dangerous as it could move or be
crushed during sudden braking or a
collision and cause injury.
CAUTION
Make sure the luggage compartment
cover is firmly secured. If it is not
firmly secured, it could unexpectedly
disengage resulting in injury. The luggage compartment can be accessed
by opening the liftgate when the straps are
attached to the sides of the liftgate.
Strap
Removing the cover
This cover can be removed for more room.
1. Remove the straps from the hooks.

Before Driving
Doors and Locks
WARNING
Close the trunk lid, be sure the seat
backs are latched and do not allow
children to play inside the vehicle:Leaving the trunk lid open or leaving
children in the vehicle with the keys is
dangerous. Children could open the
trunk lid and climb inside resulting
in possible injury or death from heat
exposure.
Always keep the car from being a
tempting place to play by latching the
rear seats, doors and the trunk, and
keeping the keys where children can not
play with them: Leaving children or animals
unattended in a parked vehicle is
dangerous. Babies left sleeping and
children who lock themselves in cars or
trunks can die very quickly from heat
prostration. Do not leave your children
or pets alone in a car at any time. Do
not leave the car, the rear folding seats
or the trunk unlocked.
Opening the Trunk Lid from the
Inside
Slide the inside trunk release lever in the
direction of the arrow. The lever is made
of material that will glow for hours in the
darkness of the trunk following a brief
exposure to ambient light.
The inside trunk release lever is located on
the inside of the trunk lid.

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
(U.S.A. and Canada)
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.

CAUTION
(U.S.A. and Canada)
If the check fuel cap warning light
illuminates, the fuel-filler cap may not
be properly installed. If the warning
light illuminates, park your vehicle
safely off the right-of-way, remove the
fuel-filler 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
Modification and Add-On
Equipment
Mazda cannot guarantee the immobilizer
and the theft-deterrent systems' operation
if the system has been modified or if any
add-on equipment has been installed.
CAUTION
To avoid damage to the vehicle, do
not modify the system or install any
add-on equipment to the immobilizer
and the theft-deterrent systems or the
vehicle.
Immobilizer System
The immobilizer system allows the
engine to start only with a key the system
recognizes.
If someone attempts to start the engine
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
 Radio equipment like this is governed by
laws in the United States.
Changes or modifications not expressly
approved by the party responsible
for compliance could void the user's
authority to operate the equipment.
 To avoid damage to the key, do not:
 Drop the key. Get the key wet. Expose the key to any kind of
magnetic field. Expose the key to high temperatures
on places such as the dashboard or
hood, under direct sunlight.
 If the engine does not start with the
correct key, and the security indicator
light keeps illuminating or flashing, the
system may have a malfunction. Consult
an Authorized Mazda Dealer.

Before Driving
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 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
 The engine may not start and security
indicator light may illuminate or flash
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:
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
 If the security indicator light flashes
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 flashing, you will
not be able to restart it.
 Because the electr onic 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.
