2020 MAZDA MODEL 3 HATCHBACK Owners Manual (in English)

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.

oblem with the
immobilizer system or the key, consult an
Authorized Mazda Dealer.
CAUTION
 Radio equipment like this is governed by
laws in the United States.
Changes or modifications not expressly
approved by the party responsible for
compliance could void the user's
authority to operate the equipment.
 To avoid damage to the key, do not:
 Drop the key.
 Get the key wet.
 Expose the key to any kind of magnetic
field.
 Expose the key to high temperatures
on places such as the dashboard or
hood, under direct sunlight.
