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.

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. The luggage compartment can be accessed
by opening the liftgate when the straps are
attached to the sides of the liftgate.

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

vehicle.
Immobilizer System
The immobilizer system allows the
engine to start only with a key the system
recognizes.

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.
