SPORT HYBRID i-MMD SYSTEM MAIN COMPONENTS
Gasoline Engine– Runs the generator and under certain
conditions, drives the wheels directly.
Generator– Starts the engine and generates electric power
when driven by the gasoline engi ne to supply electricity to
power the electric motor and/or to charge the High Voltage
battery.
Electric Motor– Provides propulsion to drive the wheels in
conjunction with the gasoline engine in certain conditions and
provides electricity to the High Voltage battery through
regenerative braking.
High Voltage Battery– Provides electrical storage and serves
as a power source for the electric motor.
Learning about the High Voltage battery’s characteristics will
help you get the best handling and maximize the range of your
electric vehicle. (P402)
●Sounds Unique to the SPORT HYBRID i-MMD System
When you first start driving this vehicle, you will likely hear so me unfamiliar sounds, particularly when you turn on the power system, or
while you are driving or accelerating from a stop. Some of thes e sounds are unique to this vehicle‘s powertrain, fuel, and climate control
systems; others are similar to sounds generated by conventional automobile s 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 unusual noise should one develop.
After shutting off the engine, you ma y 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.

or to the High Voltage battery
for charging.

•The electric motor provides
electricity to the High Voltage

e Button
AUTO Mode
When driving, your vehicle is pr opelled exclusively by the electric
motor, exclusively by the gasoline engine, or by a combination of
the two. The system selects which propulsion source is most
appropriate and automatically switches to it.
EV Mode
When EV mode is activated, your vehicle is propelled exclusively by
the electric motor.
When you press the e button and select EV mode, EV mode is
enabled and the EV mode indicator comes on. When you press the
e button again and select AUTO mode, the AUTO mode indicator
comes on.
Shifts in vehicle, driving, or road conditions may automatically
cancel EV mode and/or keep the system from manually switching
into EV mode. When this happens, the beeper sounds and a
message appears on the driv er information interface.
CHARGE Mode
When CHARGE mode is activated, the engine starts and the High
Voltage battery begins charging.
When you press and hold the e button, CHARGE mode is enabled
and the CHARGE mode indicator comes on. When you press and
hold the e button again and select AUTO mode, the AUTO mode
indicator comes on. By pressing and holding the e button, you can
select a mode to change to, and the indicator for the selected mode
will come on.
Shifts in vehicle, driving, or road conditions may automatically
cancel CHARGE mode and/or keep the system from manually
switching into CHARGE mode. When this happens, the beeper
sounds and a message appears on the driver information interface.

Quick Reference Guide
●Regenerative Energy and Regenerative BrakingWhen decelerating without the accelerator being depressed or the brake pedal being applied, or
while driving downhill, the electric motor acts as a generator that recovers a portion of the
electrical energy that was used to accelerate th e vehicle. This regenerative braking slows the
vehicle in a manner similar to engine braking in a gasoline-powered vehicle.
●Auto Engine Stop/Start
Your vehicle’s gasoline engine automatically stops running duri ng vehicle operation or restarts while the vehicle is stationary when it is
appropriate.
In the following cases, however, au to engine stop may not activate.
•The vehicle momentarily needs additional power for aggressive acceleration, or driving uphill or at high speed.•The climate control system is in heavy use.
•The High Voltage battery temperature is high or low.
•The High Voltage battery is too low on charge.

Safety Precautions
Do not touch the High Voltage systemAttempting to take a High Voltage system component apart or disconnect one of its wires
can cause severe electrical shock. Make sure that any maintenance or repairs to the High
Voltage system are performed by a Honda dealer.
If a crash occurs●Be careful of electric shock hazard.
u If a severe crash damages your vehicle’s Hi gh Voltage system, there is a possibility of
electrical shock due to exposed Hi gh Voltage components or wires. If this happens, do not
touch any of the High Voltage system components or any of its orange wires.
●Avoid contact with High Voltage battery fluid.
u The High Voltage battery contains a flammable electrolyte that could leak as a result of
a severe crash. Avoid skin or eye contact with the electrolyte as it is corrosive. If you
accidentally come into contac t with the electrolyte, rinse the exposed skin or flush your
eyes with copious amounts of water for at least five minutes, and seek medical attention
immediately.
●Use a fire extinguisher for an electrical fire.
u Attempting to extinguish an electrical fire with even a small quantity of water, from a
garden hose for instance, can be dangerous.
●Any time the vehicle is damaged in a crash, have it repaired by a dealer.
Emergency Shutdown System fo r the High Voltage SystemIf the vehicle is involved in a crash, the em ergency shutdown system will activate depending
on the severity of the impact. When the system activates, the High Voltage system
automatically shuts down, and the vehicle can no longer move under its own power. To
return the High Voltage system back to normal operation, consult a dealer.
Honda collects and recycles High Voltage batteries used in its vehicles – consult a dealer for
more information.
Do not cover the air intake.
If the air intake is obstructed
during vehicle operation, the High
Voltage battery can become too
hot. To protect the battery, the
system may start to limit the
battery’s output and cause the
power system and 12-volt battery
charging system indicators to come
on.
