The driver's door lock knob cannot be
used while the driver's door is open. Trunk Lid WARNING Never allow a person to ride in the
trunk:
Allowing a person to ride in the trunk
is dangerous. The person in the trunk
could be seriously injured or killed
during sudden braking or a collision.
Do not drive with the trunk lid open:
Exhaust gas in the cabin of a vehicle
is dangerous. An open trunk lid in a
moving vehicle will cause exhaust
gas to be drawn into the cabin. This
gas contains CO (carbon monoxide),
which is colorless, odorless, and highly
poisonous, and it can cause loss of
consciousness and death. Moreover, an
open trunk lid could cause occupants
to fall out in an accident.
CAUTION 
Before opening the trunk lid, remove
any snow and ice accumulation on it.
Otherwise, the trunk lid could close
under the weight of the snow and ice
resulting in injury. 
Be careful when opening/closing the
trunk lid during strong winds. If a strong
gust blows against the trunk lid, it could
close suddenly resulting in injury. 
Fully open the trunk lid and make sure
that it stays open. If the trunk lid is only
opened partially, it could slam shut
by vibration or wind gusts resulting in
injury. 
When loading or unloading luggage in
the trunk, turn off the engine. Otherwise,
you could get burned by the heat of the
exhaust gas.

Doors and Locks
*Some models.Closing the trunk lid
Use both hands to push the trunk lid down
until the lock snaps shut. Do not slam it.
Pull up on the trunk lid to make sure it is
secure.
Inside Trunk Release
Lever *
Your vehicle is equipped with an inside
trunk release lever that provides a means
of escape for children and adults in the
event they become locked inside the trunk.
No matter how careful adults might be
with keys and locking their cars, parents
should be aware that children may be
tempted to play around vehicles and use
the trunk as a hiding place.
Adults are advised to familiarize
themselves with the operation and location
of the inside trunk release lever so that
all children can be told about it in an
appropriate way, keeping in mind that
most vehicles do not have such levers.
WARNING Close the trunk lid, do not allow children
to play inside the trunk:
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
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 trunk unlocked.

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.

3 –48 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.
OperationNOTE 
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. 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 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.
