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.

Blind Spot Monitoring (BSM) System
The Blind Spot Monitoring (BSM) system is designed to assist the driver in checking the
area to the rear of the vehicle on both sides during lane changes by ale\
rting the driver to the
presence of vehicles approaching from the rear in an adjacent lane.
The Blind Spot Monitoring (BSM) system detects vehicles approaching from the rear while
traveling in the forward direction at a speed of 10 km/h (6.3 mph) or \
faster and turns on the
Blind Spot Monitoring (BSM) warning lights equipped on the door mirrors depending on
the conditions. If the turn signal lever is operated to signal a lane ch\
ange in the direction
in which the Blind Spot Monitoring (BSM) warning light is illuminated, the system warns
the driver of a vehicle in the detection area by flashing the Blind Spot Monitoring (BSM)
warning light and activating a beep sound.
The detection area on this system covers the driving lanes on both sides\
of the vehicle and
from the rear part of the front doors to about 50 m (164 ft) behind th\
e vehicle.
