M Hybrid

M Hybrid uses the Integrated Starter-Generator (ISG) with excellent power generation efficiency 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 after the i-stop function (idling stop).

Charging the M Hybrid battery

The M Hybrid battery is charged automatically by the engine power and deceleration regeneration. Therefore, it is not necessary to charge the battery from outside of the vehicle.

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 expert repairer (we recommend an Authorised Mazda Repairer).

If an Accident Occurs

If the vehicle receives an impact of a certain level or greater in a collision, M Hybrid may stops. 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 expert repairer (we recommend an Authorised Mazda Repairer).

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 large amounts of water is available such as from a fire hydrant.
