2021 MAZDA MODEL 3 HATCHBACK roof

▼Side Air Bags
The side air bags are mounted in the
outboard sides of the front seatbacks.
When the air bag crash sensors detect
a side impact of greater than moderate
force, the system in
flates the side air
bag only on the side in which the
vehicle was hit. The side air bag in flates
quickly to reduce injury to the driver or
front passenger's chest caused by
directly hitting interior parts such as a
door or window.
For more details about air bag
deployment, refer to "SRS Air Bag
Deployment Criteria" (page 2-67).
(With Front Passenger Occupant
Classi fication System)
In addition, the front passenger side air
bag is designed to only deploy in
accordance with the total seated
weight on the front passenger seat. For
details, refer to the front passenger
occupant classi fication system (page
2-70).

▼ Curtain Air Bags
The curtain air bags are mounted in the
front and rear window pillars, and the
roof edge along both sides.
When the air bag crash sensors detect
a side impact of greater than moderate
force, the curtain air bag in
flates
quickly and helps to reduce injury
mainly to the driver and front and rear
outboard passengers' heads caused by
directly hitting interior parts such as a
door or window.
For more details about air bag
deployment, refer to "SRS Air Bag
Deployment Criteria" (page 2-67).
In a side impact:
Greater than moderate impact to one
side of the vehicle will cause the
curtain air bag on that side only to
in flate.

Only one side curtain air bag will
deploy on the side of the vehicle that
receives the force of an impact.

Door Locks
▼Door Locks
WARNING
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
fi
nd 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, fuel-filler
lid, and liftgate 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 con firm 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.

Moonroof*
▼Moonroof
The moonroof can be opened or
closed when operating the overhead
tilt/slide switch at the front seats.
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
it.
