Door Locks
WA R N I N G
Always take all children and pets with you
or leave a responsible person with them:
Leaving a child or a pet unattended in a
parked vehicle is dangerous. In hot
weather, temperatures inside a vehicle can
become high enough to cause brain
damage or even death.
Do not leave the key in your vehicle with
children and keep them in a place where
your children will not find or play with
them:
Leaving children in a vehicle with the key is
dangerous. This could result in someone
being badly injured or even killed.
Keep both doors locked when driving:
Unlocked doors in a moving vehicle are
dangerous. Passengers can fall out if a
door is accidentally opened and can more
easily be thrown out in an accident.
Always close both the windows and
convertible top, lock the doors and take the
key with you when leaving your vehicle
unattended:
Leaving your vehicle unlocked is dangerous
as children could lock themselves in a hot
vehicle, which could result in death. Also, a
vehicle left unlocked becomes an easy
target for thieves and intruders.
After closing the doors, always verify that
they are securely closed:
Doors not securely closed are dangerous, if
the vehicle is driven with a door not
securely closed, the door could open
unexpectedly resulting in an accident.
Always confirm the safety around the
vehicle before opening a door:
Suddenly opening a door is dangerous. A
passing vehicle or a pedestrian could be hit
and cause an accident.
CAUTION
 Always confirm the conditions around
the vehicle before opening/closing the
doors and use caution during strong
winds or when parked on an incline. Not
being aware of the conditions around
the vehicle is dangerous because fingers
could get caught in the door or a passing
pedestrian could be hit, resulting in an
unexpected accident or injury.
 If the power window does not go up or
down automatically because the battery
is dead, slowly open/close the power
window while pressing the glass inward.
Otherwise, the power window may
contact the convertible top/roof and the
door cannot be opened/closed resulting
in damage to the window.
NOTE
Always stop the engine and lock the
doors. In addition, to prevent theft of
valuables, do not leave them inside the
cabin.

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.
WA R N I N G
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.

compartment.
 Do not raise or lower the convertible top in a strong wind as it could damage the
convertible top or cause an unexpected accident.
NOTE
The power windows go down automatically in conjunction with the convertible top
opening/closing. However, this is a function for improving the operability, and it does not
mean there is a problem. If the vehicle battery is disconnected for vehicle maintenance or
other reasons, the power windows will not go down automatically. If the power windows
do not go down, the automatic open/close mechanism for the windows must be reset.
Refer to Auto-opening on page 3-34.

Modification and Add-OnEquipment
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 pr oblem 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.

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. 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 indica
tor 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.
