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 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 the liftgate/
trunk lid 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 and the liftgate/
trunk lid, always verify that they are
securely closed:
Doors and the liftgate/trunk lid not
securely closed are dangerous, if the vehicle
is driven with a door and the liftgate/trunk
lid not securely closed, the door and the
liftgate/trunk lid could open unexpectedly
resulting in an accident.
Always confirm the safety around the
vehicle before opening a door and the
liftgate/trunk lid:
Suddenly opening a door and the liftgate/
trunk lid 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 the liftgate/trunk lid 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 and the liftgate/trunk
lid or a passing pedestrian could be hit,
resulting in an unexpected accident or
injury.

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.
