Energy flow
The hybrid system informs the drivers its
energy flow in various operating modes.
While driving, the current energy flow is
specified in 11 modes.
Vehicle stop
ONX4E040024
The vehicle is stopped.
(No energy flow)
EV propulsion
ONX4EHQ010002
Only the motor power is used to drive the
vehicle.
(Battery → Wheel)
Power assist
ONX4EHQ010003
Both the motor and the engine power are
used to drive the vehicle.
(Battery & Engine → Wheel)
Engine only propulsion
ONX4EHQ010004
Only the engine power is used to drive
the vehicle.
(Engine → Wheel)

Foreword / Hybrid System Overview

Engine generation
ONX4EHQ010005
When the vehicle is stopped, the high-
voltage battery is charged up by the
engine.
(Engine → Battery)
Regeneration
ONX4EHQ010006
The high-voltage battery is charged up
by the regenerative brake system.
(Wheel → Battery)
Engine brake
ONX4EHQ010007
The engine braking is used to decelerate
the vehicle.
(Wheel → Engine)
Power reserve
ONX4EHQ010008

battery. The motor power is used to drive
the vehicle.
(Engine → Battery → Wheel)
Engine generation/regeneration
ONX4E040025
The engine and regenerative brake
system charges up the high-voltage
battery.
(Engine & Wheel → Battery)
Engine brake/regeneration
ONX4EHQ010010

e-Handling (Electrically Assisted
Handling Performance)/e-EHA
(Electrically Evasive Handling
Assist)
e-Handling controls the electric motor
while turning around to improve the
handling performance, driving safety,
convenience and ride comfort.
e-EHA connects FCA (Forward Collision
Avoidance Assist) and the electric motor
to provide assists to avoid collision
so that prompt collision avoidance is
available while FCA warning appears.
Ãe-Handling stands for Electrically
Assisted Handling Performance.
Ãe-EHA means Electrically Evasive
Handling Assist.
Operation condition
e-Handling starts to work by identifying
enter or exit condition if the driver
operates the steering wheel over a
certain level when the vehicle speed is
between 40km/h and 120km/h.
e-EHA operates if there is urgent steering
wheel operation while FCA (Forward
Collision Avoidance Assist) warning
appears
Operation cancel
-When ESC operates
-When ABS works
CAUTION
The system does not work under the
following conditions.
-When the ESC operation stop light
is on
-When it does not work due to a
malfunction of electronic device
-When the manual transmission mode
is set
-The gear shift is not in D (Drive)
Information
Please refer to the chapter 6 “Paddle shift
(manual transmission mode) of automatic
transmission (electronic transmission
button)”
