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.
 y A variable voltage alternator is incorporated in the power generator whic\
h converts
the kinetic energy to electricity and can generate electricity ef ¿ ciently according to the
vehicle conditions.
 y  A capacitor is used to store large amounts of electricity instantly which can be utilized
quickly.
 y  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
SignalWarning
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 Authorized Mazda Dealer 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 malfuncti\
on of the
alternator or of the charging system.
Drive to the side of the road and park off the right-of-way. Consult an Authorized
Mazda Dealer.CAUTION
Do not continue driving when the charging system warning light is illuminated because the engine could stop unexpectedly.
Engine Oil Warning LightThis warning light indicates low engine oil pressure.
CAUTION
Do not run the engine if the oil pressure is low. Otherwise, it could result in extensive engine damage.
If the light illuminates or the warning indication is displayed while dr\
iving:
1.Drive to the side of the road and park off the right-of-way on level ground.
2.Turn off the engine and wait 5 minutes for the oil to drain back into the oil p\
an.
3.Inspect the engine oil level 6-30. If it's low, add the appropriate amount of engine
oil while being careful not to overfill.
CAUTION
Do not run the engine if the oil level is low. Otherwise, it could result in extensive engine damage.
4.Start the engine and check the warning light.
If the light remains illuminated even though the oil level is normal or \
after adding oil,
stop the engine immediately and have your vehicle towed to an Authorized Mazda
Dealer.
