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 fi nd 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 all 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 all the windows and
moonroof, 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 confi rm 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.
NOTE
 y When the ignition is switched to ACC
or ON, the vehicle lock-out prevention
feature prevents you from locking
yourself out of the vehicle.
 All doors and the liftgate will automatically unlock if they are locked
using the power door locks with any
door open.
 The vehicle lock-out prevention feature does not operate while the ignition is
switched off.
 When any door is opened from the outside while the key is inside the
vehicle, the closed doors are locked. All
the doors are automatically unlocked by
closing the open door.
(With the advanced keyless function) The beep sound is heard for about 10 seconds to notify the driver that the key
has been left in the vehicle.
(Without the advanced keyless
function)
 The horn sound is heard twice to notify the driver that the key has been left in
the vehicle.

Before Driving
Doors and Locks
Rear Door Child Safety Locks
These locks are intended to help prevent
children from accidentally opening the
rear doors. Use them on both rear doors
whenever a child rides in the rear seat of
the vehicle.
If you slide the child safety lock to the
lock position before closing that door, the
door cannot be opened from the inside.
The door can only be opened by pulling
the outside handle.
LockUnlock
Liftgate/Trunk Lid
WARNING
Never allow a person to ride in the
luggage compartment/trunk:
Allowing a person to ride in the
luggage compartment/trunk is
dangerous. The person in the luggage
compartment/trunk could be seriously
injured or killed during sudden braking
or a collision.

Do not drive with the liftgate/trunk lid
open: Exhaust gas in the cabin of a vehicle is
dangerous. An open liftgate/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 liftgate/trunk lid could cause
occupants to fall out in an accident.

Do not stack or leave loaded luggage
unsecured in the luggage compartment: Otherwise, the luggage may move
or collapse, resulting in injury or an
accident. In addition, do not load
luggage higher than the seatbacks. It
may aff ect the side or rear fi eld of view.

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 fi rmly secured. If it is not
fi rmly secured, it could unexpectedly
disengage resulting in injury.

Security System
Modifi cation and Add-On
Equipment
Mazda cannot guarantee the immobilizer
and the theft-deterrent systems' operation
if the system has been modifi ed 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 the
theft of the vehicle.
If you have a problem with the
immobilizer system or the key, consult an
Authorized Mazda Dealer.
CAUTION


3–42
Before Driving
Security System
NOTE
 y 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.
 y Always keep a spare key in case one
is lost. If a key is lost, consult an
Authorized Mazda Dealer as soon as
possible.
 y 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
 y The engine may not start and security
indicator light may illuminate or fl ash
if the key is placed in an area where it
is diffi cult 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.
 y 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 push button
start is pressed from ON to off.
The security indicator light in the
instrument cluster fl ashes 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
fl ashing, 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
 y If the security indicator light fl ashes
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 fl ashing, you will
not be able to restart it.
 y 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.
