Quick Reference Guide
SPORT HYBRID i-MMD Plug-in
(intelligent Multi-Mode Drive Plug-in)
Your Honda SPORT HYBRID i-MMD Plug-in vehicle uses both an electric motor and a gasoline engine as propulsion sources, with the electric
motor receiving electricity from an internal Hi gh Voltage battery and/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 the 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 generator.
The system offers three different propulsion sources: You can dr ive with the electric motor, the gasoline engine, or both the e lectric motor
and the gasoline engine (hybrid). Under most driving conditions , the system automatically selects an appropriate propulsion source based
on the current driving needs.
The High Voltage battery can be charged while the vehicle is running or while it is plugged in. 2 Power Source and Charging (P15)

Quick Reference Guide
There are three drive modes: ECON, NORMAL, and SPORT
Regardless of the drive mode that is activated, 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 the 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.
To maintain fuel efficiency, keep steady pressure on the accelerator pedal and avoid aggressive acceleration and deceleration.

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 engine has not been sufficiently warmed up.●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 SourceWhen the High Voltage battery is sufficiently charged, the vehicle is propelled solely by the electric motor. When the remaining 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 charging of
the battery by pressing and holding the HV button.
2 Switching to HV CHARGE (P17)
Hybrid SourceIn 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 SourceWhen 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 (P461)
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.
uHV Charge Mode will not completely charge the HV Battery to 100%.
When charging from an external source, you ca n schedule the start and end time for charging.
(P473)
Regenerative Energy and Regenerative BrakingWhen 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.

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
canceled.
●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.

HV Charge
To enable HV Charge, press the HV button until the HV Charge indicator turns on.
While the vehicle is in HV Charge, the High Voltage battery will continue to charge until the battery charge level display reac hes 12
segments. Once the battery reaches this leve l, the vehicle switches to HV. You can cancel HV Charge before the battery reaches 12 segments
by pressing the HV button.
When the vehicle is in HV Charge, priority is given to the charging of the High Voltage battery. While the battery is being charged, the
engine may run at a higher RPM than usual. The time it takes for the battery to be charged to 12 segments varies depending on d riving
conditions.
The high voltage battery can be charged to 12 segments in after about 1 hour of high-speed driving. HV Charge is not recommende d for
city driving or other driving situations when you need to stop frequently or driv e slowly. In these situations, press the HV button again to
disable HV Charge. If you are in HV and approaching a destination where the vehicle can be charged, you can turn off HV and use the
remaining battery power to drive.

Energy Efficiency
As with a gasoline powered vehicle, the fuel efficiency and the range of this vehicle is most impacted by the driver’s driving style. Aggressive
acceleration and high-speed driving can easily trigger the system to switch the propulsion source to the gasoline-powered engin e. Climate
control system usage also has a strong impact with heavy usage ne gatively affecting the vehicle’s range. In particular, when it is cold
outside, climate control system consumes a lot of power, so th e vehicle’s driving range on electric power can be reduced. The c apacity of the
HV battery will be less when the temperature is low.
Battery Type
There are two types of batteries used in this vehicle, a standa rd 12-volt battery that powers the airbags, the interior and exterior lights, and
other standard 12-volt systems, and a high voltage battery that is used to power the propulsion motor and recharge the 12-volt battery.
Hybrid Vehicles
High voltage parts and high voltag e wires in this vehicle are sheathed in electromagnetic shielding material; therefore, the am ount of
electromagnetic waves emitted is no more gr eater than those emitted by household appliances or the electrical parts in conventional
vehicles.
Sounds Unique to the SP ORT HYBRID i-MMD Plug-in (intelligent Multi-Mode
Drive Plug-in)
When you first start driving this vehicle, you likely will hear some unfamiliar sounds, particularly when you first turn on the power system,
while driving, and just after parking. Some of these sounds are unique to this vehicle‘s powertrain, fuel, and climate control systems; others
are similar to sounds generated by conventional automobiles that typically are masked by louder noises absent from a vehicle of this design.
These sounds are not a cause for concern, and you will soon recognize them as normal and thus be able to detect any new or unus ual noise
should one develop.
After shutting off the engi ne, you may hear certain noises coming from the vehicle. Here’s the lowdown:
●Noise from Under Vehicle: This noise is caused by the vacuum pump inside the fuel evaporation leakage check module (ELCM).
Depending on conditions, the pump will come on for about 15 minutes about 5 to 10 hours after engine shutoff. This noise is just normal
vehicle operation and doesn’t indicate a vehicle problem.
