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).

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

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 expert repairer,
we recommend an Authorised Mazda
Repairer.
 


 The warning light notifi es 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 4-41 .
 Refer to Power Steering Warning Buzzer
on page 7-53 .
CAUTION
Never hold the steering wheel to the
extreme left or right for more than
5 seconds with the engine running.
This could damage the power steering
system.

When Driving
i-ACTIVSENSE
NOTE
  During headway control travel, the system accelerates and decelerates your vehicle
in conjunction with the speed of the vehicle ahead. However, if it is necessary to
accelerate for a lane change or if the vehicle ahead brakes suddenly causing you to
close in on the vehicle rapidly, accelerate using the accelerator pedal or decelerate
using the brake pedal depending on the conditions.
  While the Mazda Radar Cruise Control (MRCC) system is in use, it does not cancel
even if the selector lever (automatic transaxle)/shift lever (manual transaxle) is
operated and any intended engine braking will not occur. If deceleration is required,
lower the vehicle speed setting or depress the brake pedal.
  The brake lights are illuminated while the Mazda Radar Cruise Control (MRCC)
automatic braking is operating, however, they may not be illuminated while the
vehicle is on a down slope at the set vehicle speed or travelling at a constant speed and
following a vehicle ahead.
  The Mazda Radar Cruise Control (MRCC) warning light (amber) fl ashes when the
system has a malfunction.
 Refer to Warning Lights on page 4-41 .
