High-Voltage Battery Monitoring System This vehicle is equipped with a monitoring system that compiles
data about your vehicle and drivin g conditions and transmits that
data to Honda at regular intervals as determined at the discretion
of Honda. This data includes information on but not limited to the
following:
● Vehicle location, distance dr iven, warning indicators and
messages, and vehicle speed
● High-Voltage Battery system control and power generation
The system does not record audio or images.
Data collected is used for the sole purposes of technical diagnoses,
preventive maintenance, resear ch and vehicle development.
Neither Honda nor any third party receiving data will use the data
for any other purpose withou t first obtaining customer
authorization. 18 CLARITY PHEV CSS-31TRW6000.book 2 ページ ２０１７年８月３１日　木曜日　午後２時４ ９分

SPORT HYBRID i-MMD Plug-in
(Intelligent Multi-mode Drive Plug-in) Your Honda SPORT HYBRID i-MMD Plug-in vehicl e uses both an electric motor and a gasoline engine as propulsion sources, with the electric
motor receiving electricity from an internal High Voltage battery or internal generator.
When the High Voltage battery has sufficient charge levels, the vehicle is propelled solely by the power supplied by the High V oltage
battery (Electric) or by a combination of power supplied by both the High Voltage battery and th e generator which is driven by the engine.
When the High Voltage battery charge drops to low levels, the ve hicle is propelled by power supplied by the engine-driven gener ator.
The system offers three different propulsion sources: You can dr ive with the electric motor, th e gasoline engine, or both the e lectric motor
and the gasoline engine (hybrid). Under most driving conditions , the system automatically selects an appropriate propulsion sou rce based
on the current driving needs.
You may also choose to use the propulsion sources as follows:
● EV - While driving in city traffic or at slow speed.
● HV - During highway driving at high speeds.
● HV Charge - To charge the High Voltage battery while driving.
The High Voltage battery can be charged while the vehicle is running or while it is plugged in.

Quick Reference Guide There are three drive modes: ECON, NORMAL, and SPORT
Regardless of the drive mode that is acti vated, when the accelerator pedal is depr essed past a certain point, the engine starts . When this
occurs, electrical power generated by the en gine combines with electrical power from th e battery to provide greater driving force. If you
select ECON mode, the threshold for the engine to provide additional power is higher than it is when the vehicle operates under either of
the two sources. Note that if the accelerator pedal is depressed past the point at which you feel a click, the engine will star t in the ECON
mode with the HV indicator off.
2 HV Button (P16)
To maintain fuel efficiency, keep steady pressure on the accelerator pedal and avoid aggressive acceleration and deceleration.

Quick Reference Guide
Auto Engine Stop/Start The car will select the appropriate source of power depending on the drive mode you select.
As a result, the engine will automatically start or stop as needed to either charge the battery or provide supplemental power.
Under certain circumstances, the engine may turn on or, if it is already on, it may not turn off.
● You are going uphill or accelerating aggressively.
● The climate control system is in heavy use.
● The Ambient temperature is too hot or too cold.
● The High Voltage Battery state of charge is very low.
● The vehicle is running a system check.
System Check When the engine initially starts (between the time the POWER button is turned on and turned of f), the vehicle conducts a system check.
● While the check is being conducted, the engine may periodically turn on and off. This, however, is normal.
● The curved blue line in the POWER / CHARGE Gauge will not appear during the system check ( EV indicator may still turn on).
● Once the engine starts, it will continue to run until the system reaches operating temperature.
The curved blue line in the POWER / CHARGE Gauge will reappear once the system check is completed.

Power Source and Charging Electric Source When the High Voltage battery is sufficiently charged, the vehicl e is propelled solely by the electric motor. When the remainin g power of
the High Voltage battery drops to a certain level, the vehicle switches to HV.
u To maintain charge levels, you can, at any time, use the HV button to switch the vehicle to HV.
2 Switching to HV (P16)
u If the High Voltage battery charge drops below levels that are necessary for the vehicle to run in Electric, you can enable cha rging of
the battery by pressing and holding the HV button.
2 Switching to HV CHARGE (P17)
Hybrid Source In hybrid, the electric motor receives powe r either from the High Voltage battery or from the generator which is driven by the engine, or
from both the High Volt age battery and generator.
Engine Source When the vehicle is driving under light load within a certain speed range, the engine provides direct power to the wheels.
Charging the High Voltage Battery (P455)
There are a number of ways to charge the High Voltage battery. You can:
● Use the Level 2 240V charger, or the portable charging cable located in the trunk.
● Use a public charging station.
● Enable HV Charge and let the battery charge while the vehicle is being driven.
When charging from an external source, you ca n schedule the start and end time for charging.
(P467)
Regenerative Energy and Regenerative Braking When the vehicle is decelerating or descending a hill, the electric motor acts as a generator that recovers
a portion of the energy that was used to accelerate the vehicle.
The regenerative force that the electric motor applie s to the wheels when it is in regenerative mode
helps to slow the vehicle down in a manner similar to engine braking which is used on conventional
vehicles. If you want to slow the vehicle down at a faster rate without using the brakes, you can use the
deceleration paddle selector to increase the resistive force. 18 CLARITY PHEV CSS-31TRW6000.book 15 ページ ２０１７年８月３１日　木曜日　午後２時 ４９分

Quick Reference Guide HV Button You can enable HV or HV Charge by pressing the HV button.
The HV indicator comes on regardless of which source you have
enabled. If you press the HV button again, or set the power mode
to VEHICLE OFF or ACCESSORY, the source you have selected will be
cancelled.
● HV
To enable HV, press the HV button. In HV, the engine may run at
times to drive the generator so that battery charge levels can be
maintained.
