▼ 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.

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.
Before Driving

*Some models.3-23
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.

Do not run the engine when inside an
enclosed area:
Running the engine inside an enclosed
area, such as a garage, is dangerous.
Exhaust gas, which contains poisonous
carbon monoxide, could easily enter the
cabin. Loss of consciousness or even death
could occur.
Open the windows or adjust the heating or
cooling system to draw fresh air when
idling the engine:
Exhaust gas is dangerous. When the vehicle
is stopped with the windows closed and the
engine running for a long time even in an
open area, exhaust gas, which contains
poisonous carbon monoxide, could enter
the cabin. Loss of consciousness or even
death could occur.
Clear snow from underneath and around
your vehicle, particularly the tail pipe,
before starting the engine:
Running the engine when a vehicle is
stopped in deep snow is dangerous. The
exhaust pipe could be blocked by the snow,
allowing exhaust gas to enter the cabin.
Because exhaust gas contains poisonous
carbon monoxide, it could cause loss of
consciousness or even death to occupants
in the cabin.Fuel-Filler Lid and Cap
▼Fuel-Filler Lid and Cap
WA R N I N G
When removing the fuel-filler cap, loosen
the cap slightly and wait for any hissing to
stop, then remove it:
Fuel spray is dangerous. Fuel can burn skin
and eyes and cause illness if ingested. Fuel
spray is released when there is pressure in
the fuel tank and the
fuel-filler cap is
removed too quickly.
Before refueling, stop the engine, and
always keep sparks and flames away from
the filler neck:
Fuel vapor is dangerous. It could be ignited
by sparks or flames causing serious burns
and injuries.
Additionally, use of the incorrect fuel-filler
cap or not using a fuel-filler cap may result
in a fuel leak, which could result in serious
burns or death in an accident.
Do not continue refueling after the fuel
pump nozzle shuts off automatically:
Continuing to add fuel after the fuel pump
nozzle has shut off automatically is
dangerous because overfilling the fuel tank
may cause fuel overflow or leakage. Fuel
overflow and leakage could damage the
vehicle and if the fuel ignites it could cause
a fire and explosion resulting in serious
injury or death.
