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 which converts
the kinetic energy to electricity and can generate electricity ef¿ ciently 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.

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 Indication/
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.
