2021 MAZDA MODEL 3 HATCHBACK warning

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
WARNING
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 o ff automatically
is dangerous because overfilling the
fuel tank may cause fuel over flow or
leakage. Fuel over flow and leakage
could damage the vehicle and if the
fuel ignites it could cause a fire and
explosion resulting in serious injury or
death.

The windows can be opened/closed
by operating the power window
switches.
WARNING
Make sure the opening is clear before
closing a window:
Closing a power window is dangerous.
A person's hands, head, or even neck
could be caught by the window and
result in serious injury or even death.
This warning applies especially to
children.
Never allow children to play with
power window switches:
Power window switches that are not
locked with the power window lock
switch would allow children to operate
power windows unintentionally, which
could result in serious injury if a child's
hands, head or neck becomes caught
by the window.
Make sure nothing blocks the window
just before it reaches the fully closed
position or while fully holding up the
power window switch:
Blocking the power window just before
it reaches the fully closed position or
while fully holding up the power
window switch is dangerous.
In this case, the jam-safe function may
not prevent the window from closing
all the way. If
fingers are caught,
serious injuries could occur.
Do not let a child put a hand or head
out of the window while driving the
vehicle:
If the person's hand or head hits
something outside the vehicle, or
sudden braking is applied, it could
result in serious injury or death.
NOTE
When driving with only 1 of the rear
windows open, your ears might
experience a resonating sound.
However, this does not indicate a
problem. The sound can be reduced
by slightly opening a front window or
by changing the size of the rear
window opening.
▼ Opening/Closing Windows
The window opens while the switch is
pressed and it closes while the switch
is pulled up with the ignition switched
ON. Do not open or close 3 or more
windows at the same time.
The front passenger's window and rear
windows can be opened/closed when
the power window lock switch on the
driver's door is in the unlocked
position. Keep this switch in the locked
position while children are in the
vehicle.

WARNING
Do not let passengers stand up or
extend part of the body through the
open moonroof while the vehicle is
moving:
Extending the head, arms, or other
parts of the body through the
moonroof is dangerous. The head or
arms could hit something while the
vehicle is moving. This could cause
serious injury or death.
Never allow children to play with the
tilt/slide switch:
The tilt/slide switch would allow
children to operate the moonroof
unintentionally, which could result in
serious injury if a child's hands, head
or neck becomes caught by the
moonroof.
Make sure the opening is clear before
closing the moonroof:
A closing moonroof is dangerous. The
hands, head, or even neck of a person,
especially a child, could be caught in it
as it closes, causing serious injury or
even death.
Make sure nothing blocks the
moonroof just before it reaches the
fully closed position:
Blocking the moonroof just before it
reaches the closed position is
dangerous.
In this case, the jam-safe function
cannot prevent the moonroof from
closing. If
fingers are caught, serious
injuries could occur.
CAUTION
 Do not sit on or put heavy items on
the area where the moonroof opens
and closes. Otherwise, the
moonroof could be damaged.
 Do not open or close the moonroof
forcefully during freezing
temperatures or snowfall. Otherwise,
the moonroof could be damaged.
 The sunshade does not tilt. To avoid
damaging the sunshade, do not push
it up.
 Do not close the sunshade while the
moonroof is opening. Trying to force
the sunshade closed could damage
