i-ELOOP
*Some models.
i-ELOOP*
i-ELOOP is a regenerative braking system. When you depress the brake pedal or use
engine braking, the kinetic energy that occurs is converted to electrical energy by the power
generator and the converted electrical energy is stored in the rechargeable battery (capacitor
and battery). The stored electricity is used as power to charge the battery and the vehicle's
electrical devices.
 A variable voltage alternator is incorporated in the power generator whic\
h converts
the kinetic energy to electricity and can generate electricity efficiently according to the
vehicle conditions.
 A capacitor is used to store large amounts of electricity instantly which can be utilized
quickly. A DC-DC converter is incorporated which steps down the stored electricity\
to voltage
useable by the vehicle's electrical devices.

Power Steering
 Power steering is only operable when
the engine is running. If the engine is
off or if the power steering system is
inoperable, you can still steer, but it
requires more physical effort.
If the steering feels stiffer than usual
during normal driving or the steering
vibrates, consult an Authorized Mazda
Dealer.
 The warning light notifies the driver
of system abnormalities and operation
conditions.
In addition, the buzzer may also activate
depending on the system abnormality or
operation condition.
Refer to Warning Lights on page
