M Hybrid uses the Integrated Starter-Generator (ISG) with excellent power

generation eꢀciency to generate electricity from the kinetic energy generated when

the vehicle decelerates. The system uses the electrical power stored in the M Hybrid

battery, which is a large-capacity battery to improve driveability and fuel economy by

reducing engine load and providing motor assist. In addition, the ISG provides quiet

engine restarting after the engine is stopped by the i-stop function (idling stop).

such as from a ﬁre hydrant.

M Hybrid Control Status Display

▼

The driver is notiﬁed of the M Hybrid

operation status by the control status

display.

The M Hybrid operation status is

displayed in the center display.

Refer to the Information section in the

Mazda Connect Owner's Manual.

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.
