On conventional vehicles, the kinetic energy that is generated when the vehicle is decelerated by applying the brakes or during engine braking ends up being discarded as heat. By utilizing this discarded kinetic energy to generate electricity and use it to power the vehicle's electrical devices and accessories such as the A/C and audio, fuel consumption can be reduced. Mazda's system for generating electricity from this kinetic energy is called the Regenerative Braking System (i-ELOOP).

A capacitor is incorporated as the device for storing the generated electricity, which can store and use large amounts of electricity instantly.

CAUTION
High-current electricity fl ows through the following areas, therefore
do not touch them.

NOTE
i-ELOOP Indicator Light/Control Status Display
The driver is notified of the i-ELOOP power generating status and the vehicle conditions by the i-ELOOP indicator light and the control status display.
i-ELOOP Indicator Light

Illuminated (vehicle without type B audio)
The light turns on during power generation.
Flashing
If the engine is started after the vehicle has not been driven for a long period of time, the i-ELOOP indicator light may flash.
Leave the engine idling and wait until the indicator light turns off.
NOTE
The steering operation will return to normal after the i-ELOOP indicator light stops flashing.
Refer to Warning Message Indicated on Display on .
Control status display (vehicles with type B audio)
The i-ELOOP power generating status is displayed in the center display.
Refer to Control Status Display on .

System
The system operates only when the driver
is in the vehicle or within operational
range while the key is being carried.
NOTE
When the battery power is low, or in
places where there are high-intensity radio
waves or noise, the operational range
may become narrower or the system may
not operate ...
