i-ELOOP
i-ELOOP *
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.

NOTE

 When installing high power consumption devices such high-output speakers, consult
an expert repairer, we recommend an Authorised Mazda Repairer.
  A difference in the fuel economy may occur depending on use conditions such as with
the A/C and headlights.
  If the capacitor is to be disposed of, always consult an expert repairer, we recommend
an Authorised Mazda Repairer. For details, go to the following URL.

i-ELOOP
i-ELOOP Indicator Light/Control
Status Display
The driver is notifi ed 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 C/type
D 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 fl ash.
Leave the engine idling and wait until the
indicator light turns off.
NOTE
  The beep will sound if the vehicle is
driven while the i-ELOOP indicator
light is fl ashing. In addition, if you
turn the steering wheel while the
light is fl ashing, it will feel heavier
than normal, but this does not
indicate an abnormality. Stop the
vehicle in a safe location with the
engine running and do not attempt to
turn the steering wheel. The steering
operation will return to normal after
the i-ELOOP indicator light stops
fl ashing.

(Vehicles with type C/type D audio) A notifi cation is displayed in the
centre display and the i-ELOOP
indicator light fl ashes at the same
time.
 Refer to Warning Message Indicated
on Display on page 7-47 .
Control status display (vehicles with
type C/type D audio)
The i-ELOOP power generating status is
displayed in the centre display.
Refer to Control Status Display on page
4-95 .

When Driving
Fuel Economy Monitor
Fuel Economy Monitor *
For vehicles with type C/type D audio, the Control Status, Fuel Consumption, and
Effectiveness are switched and displayed by operating each icon in the display.
In addition, after completing a trip, the total energy effi ciency to date is displayed in the
ending display when the ending display is turned on.
1. Select the
icon on the home screen to display the applications screen.
2. Select the “Fuel Economy Monitor”.
3. Operate the commander switch or touch the screen and display the menu.
NOTE
When the menu is displayed by touching the screen, the display is hidden automatically
after 6 seconds.
4. Select the icon in the menu and perform the operation. Each icon operates as follows:
Indication on display Control status
Hides the menu display.
Displays the application screen.
Switches the Fuel Economy Monitor in the order of
Control Status, Fuel Consumption, and
Effectiveness.

Fuel Economy Monitor
Fuel Consumption Display
Information regarding the fuel economy is displayed.
Indication on display Control status
Displays the fuel economy for the past 60 minutes. Displays the fuel economy every minute for the
past 1 to 10 minutes.
Displays the fuel economy every 10 minutes for the
past 10 to 60 minutes.
Displays the average fuel economy over the past 5
resets and after the current reset.
Calculates the average fuel economy every minute
after vehicle travel begins, and displays it.
NOTE
  The fuel economy data can be reset by doing the following operation:




 Press the reset switch from the menu screen.



 When the function which synchronizes the fuel economy monitor and the trip meter
is on, reset trip A of the trip meter.
 


 Delete the average fuel economy information displayed in the trip computer. 

 After resetting the fuel economy data, “-- -” is displayed while the average fuel
economy is calculated.
Control Status Display
The i-stop operation status and the i-ELOOP power generating status are displayed.
Indication on display Control status
