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.
