2020 MAZDA MODEL 3 HATCHBACK roof

Do not place luggage or other objects
under the front seats:
Placing luggage or other objects under the
front seats is dangerous. The components
essential to the supplemental restraint
system could be damaged, and in the event
of a side collision, the appropriate air bags
may not deploy, which could result in
death or serious injury. To prevent damage
to the components essential to the
supplemental restraint system, do not
place luggage or other objects under the
front seats.
Do not operate a vehicle with damaged air
bag/seat belt pretensioner system
components:
Expended or damaged air bag/seat belt
pretensioner system components must be
replaced after any collision which caused
them to deploy or damage them. Only a
trained Authorized Mazda Dealer can fully
evaluate these systems to see that they will
work in any subsequent accident. Driving
with an expended or damaged air bag or
pretensioner unit will not afford you the
necessary protection in the event of any
subsequent accident which could result in
serious injury or death.
Do not remove interior air bag parts:
Removing any components such as the
front seats, front dashboard, the steering
wheel or parts on the front and rear
window pillars and al ong the roof edge,
containing air bag parts or sensors is
dangerous. These parts contain essential
air bag components. The air bag could
accidentally activate and cause serious
injuries. Always have an Authorized Mazda
Dealer remove these parts.Properly dispose of the air bag system:
Improper disposal of an air bag or a vehicle
with live air bags in it can be extremely
dangerous. Unless all safety procedures are
followed, injury could result. Have an
Authorized Mazda Deal er safely dispose of
the air bag system or scrap an air bag
equipped vehicle.
NOTE
If it becomes necessary to have the
components or wiring system for the
supplementary restraint system modified
to accommodate a person with certain
medical conditions in accordance with a
certified physician, contact an
Authorized Mazda Dealer, refer to
“Customer Assistance (U.S.A.)” (page
8-2).
When an air bag deploys, a loud
inflation noise can be heard and some
smoke will be released. Neither is likely
to cause injury, however, the texture of
the air bags may cause light skin
injuries on body parts not covered with
clothing through friction.
Should you sell your Mazda, we urge
you to tell the new owner of its air bag
systems and that familiarization with all
instructions about them, from the
Owner's Manual, is important.

(With Front Passenger Occupant
Classification 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
classification system (page 2-71).

▼ 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 cra
sh sensors detect a
side impact of greater than moderate force,
the curtain air bag inflates quickly and
helps to reduce injury mainly to the driver
and front and rear outboard passengers'
heads caused by direct ly hitting interior
parts such as a door or window.
For more details about air bag
deployment, refer to "SRS Air Bag
Deployment Criteria" (page 2-68).
In a side impact:
Greater than moderate impact to one side
of the vehicle will cau se the curtain air bag
on that side only to inflate.

Only one side curtain air bag will deploy
on the side of the veh icle that receives the
force of an impact.
(With Front Passenger Occupant
Classification System)
In a roll-over:
In response to a vehicle roll-over, both
curtain air bags inflate.

Both curtain air bags will deploy after the
roll-over accident is detected.

Door Locks
▼Door Locks
WA R N I N G
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 find 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 confirm 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.
NOTE
Always stop the engine and lock the
doors. In addition, to prevent theft of
valuables, do not leave them inside the
cabin.

Moonroof*
▼Moonroof
The moonroof can be opened or closed
when operating the overhead tilt/slide
switch at the front seats.
WA R N I N G
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.
