WARNING
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 and the door
cannot be opened/closed resulting in
damage to the window.

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.

 Before lowering or raising the convertible top, stop in a safe place off the right-of-way
and park on a level surface. Make sure nothing is on the convertible top or near the back window when\
raising or
lowering the convertible top.
Even small objects may interfere and cause damage. When lowering the convertible top, make sure objects inside the vehicle \
are not blown

d correctly, the
material could harden, becomes stained, or have an uneven gloss. Do not lower the convertible top when it's wet. If the convertible top d\
ries while folded, it
will deteriorate and mold. Lowering the convertible top while it's wet can also cause water to drip\
into the passenger

amage the
convertible top or cause an unexpected accident.
NOTE
 The power windows go down automatically in conjunction with the converti\
ble 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 Operating the Power Windows on page 3-31. The windblocker reduces the amount of wind coming into the cabin from behind when

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.

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. 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.
