SPORT HYBRID i-MMD (intelligent Multi-Mode
Drive)
Your SPORT HYBRID i-MMD vehicle uses both an electric motor and a gasoline engine as propulsion sources, with the electric motor
receiving electricity from an internal High Voltage battery and/or internal generator. The High Voltage battery is charged from the
generator driven by the engine or regenerative braking.
When driving, your vehicle is propelled 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.
●Energy efficiency
As with a gasoline-powered vehicle, hybrid vehicle fuel efficien cy and driving range is most impacted by your driving style. Aggressive
acceleration and high-speed driving can easily trigger the system to switch the propulsion source to the gasoline-powered engin e.
In addition, heavy climate control system use negatively affects vehicle range and efficiency. Either of these use patterns will more quickly
reduce the High Voltage battery's state of charge.
●Battery types
There are two types of batteries used in this vehicle; a standard 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.

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 engine 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. (P491)
●Sounds Unique to the SPORT HYBRID i-MMD System
When you first start driving this vehicle, you will likely hear some unfamiliar sounds, particularly when you turn on the power system, or
while you are driving or accelerating from a stop. Some of these sounds are unique to this vehicle‘s powertrain, fuel, and clim ate control
systems; others are similar to sounds generate d by conventional automobiles that typically are masked by louder noises absent f rom 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 t o detect any
new or unusual 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.

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 the vehicle. This regenerative braking slows the
vehicle in a manner similar to engine braking in a gasoline-powered vehicle. You can control the
rate of deceleration by using the deceleration paddle selector.
●Auto Engine Stop/Start
Your vehicle’s gasoline engine automatically stops running during vehicle operation or restarts while the vehicle is stationary when it is
appropriate.
In the following cases, however, auto 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.
Predictive Eco Assist*
Predictive Eco Assist helps you drive more economically to your destination during navigation route guidance.
It predicts how much the high voltage battery can be charged by regenerative braking when driving downhill on the way to the
destination, and operates in EV mode as much as possible.
If there are any stops on the way to the destination, it works more effectively if they are set as waypoints.
If you leave the suggested navigation route, Predictive Eco Assi st may not function in a way that is suitable for your route.
You can turn Predictive Eco Assist on and off in Ve hicle Settings using the audio/information screen.

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.
uIf a severe crash damages your vehicle’s Hi gh Voltage system, there is a possibility of
electrical shock due to exposed High 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.
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.
