2022 MAZDA MODEL 3 SEDAN battery

Charging the M Hybrid battery
The M Hybrid battery is charged
automatically during engine operation
and by deceleration regeneration.
Therefore, it is not necessary to charge
the battery from outside of the vehicle.
CAUTION
Drive the vehicle for about 30 minutes
once every few months because
self-discharge occurs gradually if the
vehicle is not driven for a long period
of time. If the M Hybrid battery
becomes completely discharged and
M Hybrid cannot be activated, contact
an Authorized Mazda Dealer.
▼M Hybrid Precautions
For vehicle maintenance or repairs, or
when scrapping the vehicle, consult an
Authorized Mazda Dealer.
Handling the M Hybrid battery
Technical knowledge and skill are
necessary in handling the M Hybrid
battery.
WARNING
To ensure safe and correct handling of
the M Hybrid battery, always heed the
following precautions:

Do not remove the M Hybrid battery.
 Do not resell, transfer, or modify the
M Hybrid battery.
 Do not use the battery on vehicles
other than those equipped with the
M Hybrid battery.
If the M Hybrid battery is not handled
properly, the following may occur and
cause serious injury:
 Touching an unattended or illegally
abandoned M Hybrid battery may
cause electrocution.
 If the M Hybrid battery is used on a
vehicle other than one equipped
with M Hybrid (including modified
vehicles), accidents such as
electrocution, heat generation,
smoking, combustion, and
explosions, or an electrolyte leakage
may occur.
Scrapping Your Vehicle and Disposing
of the M Hybrid battery
The M Hybrid battery must be recycled
to prevent accidents involving it. When
scrapping your vehicle, replacing the M
Hybrid battery, or disposing of the M
Hybrid battery, consult an Authorized
Mazda Dealer. Please cooperate in
ensuring that the vehicle's M Hybrid
battery is recycled.
WARNING
Dispose of the M Hybrid battery
appropriately:
If the M Hybrid battery is not recycled
appropriately, such as by leaving it
unattended or illegally abandoning it,
some other person may touch it which
could cause electrocution leading to
serious injury.
If an Accident Occurs
If the vehicle is invo lved in a collision,
M Hybrid may stop operating. In this
case, the charging system warning light
turns on and M Hybrid cannot activate.
Park the vehicle in a safe place
immediately and contact an
Authorized Mazda Dealer.

WARNING
Never touch the areas where high
current is flowing:
Never touch a M Hybrid related part.
Otherwise, it could lead to an
electrical shock or burns causing
serious injury.
Never touch electrical wiring that may
be protruding into or outside of the
cabin:
Otherwise, it could lead to an
electrical shock or burns causing
serious injury.
Never touch any area where
electrolyte is visible or electrolyte is
leaking from the area:
If any electrolyte from the M Hybrid
battery gets in the eyes or on the skin,
it could cause loss of vision or skin
reactions. In the unlikely event that
electrolyte comes into contact with the
eyes or skin, flush with large quantities
of water immediately and seek
immediate medical attention.
Do not come near the vehicle if
electrolyte is leaking from the M
Hybrid battery:
Even if the M Hybrid battery is
damaged, large quantities of
electrolyte will not flow out due to the
internal structure of the battery,
however, in the unlikely event that it
does, it will produce steam. The steam
contains properties that can irritate the
eyes and skin, and could cause acute
poisoning if absorbed.
Never approach objects that are on
fire or extremely hot:
Electrolyte in the M Hybrid battery may
cause a fire.
If the vehicle catches fire, extinguish
the fire using an ABC fire
extinguisher:
Only extinguish a fire with water when
a high volume of water is available
such as from a fire hydrant.

Using these garage door openers can
increase the risk of serious injury or
death. For further in formation, contact
HomeLink at www.homelink.com or
www.youtube.com/HomeLinkGentex
or an Authorized Mazda Dealer.
Always check the areas surrounding
garage doors and gates for people or
obstructions before programming or
during operation of the HomeLink
system:
Programming or operating the
HomeLink system without verifying the
safety of areas surrounding garage
doors and gates is dangerous and
could result in an unexpected accident
and serious injury if someone were to
be hit.
NOTE
The programming will not be erased
even if the battery is disconnected.
▼ Pre-programming the HomeLink
System
NOTE
It is recommended that a new battery
be placed in the hand-held transmitter
of the device being programmed to
HomeLink for quic
ker training and
accurate transmission of the
radio-frequency signal.
Verify that there is a remote control
transmitter available for the device
you would like to program.
▼ Programming the HomeLink
System
The HomeLink system provides 3
buttons which can be individually
selected and programmed using the
transmitters for current, on-market
devices as follows:
1. Press and release the HomeLink
button you would like to program.
The indicator light flashes slowly in
amber when the button is pressed.
1. Indicator light
2. HomeLink button
2. Hold the hand-held transmitter 2.5
to 7.5 cm (1 to 3 in) away from the
HomeLink button you would like to
program while keeping the
indicator light in view.
NOTE
Depending on the hand-held
transmitter, it may be easier to do
the programming by holding it 15
to 20 cm (6 to 7.8 in) away from
the HomeLink button.
3. Press the hand-held transmitter button continuously until the
indicator light changes from amber
(flashing) to green
(on/flashing).

▼Garage Door Two-Way
Communication
The garage door two-way
communication is a function that
communicates with the garage door
opener and indicates whether the
garages door is open or closed using
the indicator lights in the rear view
mirror. It can indicate the status of the
garage door within a range up-to 250
m (820 ft).
NOTE
The communication range may shorten
depending on obstructions.
Programming two-way
communication
Within five seconds after programming
a new HomeLink button, both of the
garage door status indicator lights will
flash rapidly in green indicating that
the garage door two-way
communication has been established.
If the garage door status indicator
lights flash, the two-way
communication programming is
complete.

If the garage door status indicator
lights do not flash, the two-way
communication programming is not
completed. For additional HomeLink
