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.

If Trouble Arises
Warning/Indicator Lights and Warning Sounds
Signal Warning
Electronic Brake Force
Distribution System
Warning If the electronic brake force distribution control unit determines that some components
are operating incorrectly, the control unit may illuminate the brake system warning
light and the ABS warning light simultaneously. The problem is likely to be the
electronic brake force distribution system.
WARNING
Do not drive with both the ABS warning light and brake warning light
illuminated. Have the vehicle towed to an expert repairer, we recommend an
Authorised Mazda Repairer to have the brakes inspected as soon as possible:
Driving when the brake system warning light and ABS warning light are
illuminated simultaneously is dangerous.
When both lights are illuminated, the rear wheels could lock more quickly in an
emergency stop than under normal circumstances.
Charging System
Warning Light If the warning light illuminates while driving, it indicates a malfunction of the
alternator or of the charging system.
Drive to the side of the road and park off the right-of-way. Consult an expert repairer,
we recommend an Authorised Mazda Repairer. CAUTION
Do not continue driving when the charging system warning light is illuminated
because the engine could stop unexpectedly.
