Liftgate/Trunk Lid
WA R N I N G
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 affect the side or
rear field of view.
CAUTION
 Before opening the liftgate/trunk lid,
remove any snow and ice accumulation
on it. Otherwise, the liftgate/trunk lid
could close under the weight of the snow
and ice resulting in injury.
Be careful when opening/closing the
liftgate/trunk lid during strong winds. If a
strong gust blows against the liftgate/
trunk lid, it could close suddenly resulting
in injury.
 Fully open the liftgate/trunk lid and
make sure that it stays open. If the
liftgate/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 luggage compartment/trunk, turn
off
the engine. Otherwise, you could get
burned by the heat of the exhaust gas.
 Be careful not to apply excessive force to
the damper stay on the liftgate such as
by putting your hand on the stay.
Otherwise, the damper stay may bend
and
affect the liftgate operation.
Damper stay

Do not modify or replace the liftgate
damper stay. Consult an Authorized
Mazda Dealer if a liftgate damper stay is
deformed or damaged for reasons such
as a collision or if there is some other
problem.

▼Luggage Compartment
Luggage compartment cover (5-door)
WA R N I N G
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 firmly secured. If it is not firmly
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.

Strap
Removing the cover
This cover can be re moved for more room.
1. Remove the straps from the hooks.
2. Lift the end of the luggage compartment cover a little, pull it

Inside Trunk ReleaseLever (4-Door)
*
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 locki ng 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, be sure the seat backs
are latched and do not allow children to
play inside the vehicle:
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 rear seats,
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 rear folding seats
or the trunk unlocked.
▼ Opening the Trunk Lid from the
Inside
Slide the inside trunk release lever in the
direction of the arrow. The lever is made
of material that will
glow for hours in the
darkness of the trunk following a brief
exposure to ambient light.

The inside trunk release lever is located on
the inside of the trunk lid.
