Inside Trunk Release
Lever (4-door)
*
▼Inside Trunk Release Lever
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 locking 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.

Mazda3_8HZ1-EA-19G_Edition1_old 2019-5-17 13:49:03

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.

vehicle for even a short period, it is
important to switch the ignition off, as
leaving it in another position will disable
some of the vehicle's security systems and
