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. Under certain circumstances, pressing the

EV button can manually enable EV (driven only on electricity) mode.

● Energy efficiency

As with a gasoline-powered vehicle, hybrid vehicle fuel efficiency 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 engine.

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

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. (P502)

High Voltage Battery Charge Level Indicator– Displays

battery state of charge.

When the indicator:

• Displays two or less segments, EV mode is no longer available.

• Displays ten segments, battery charge level is full.

EV Button

EV mode is enabled by pressing the EV button near the shift

button.

The EV mode indicator comes on in the instrument panel when EV

mode is enabled.

Press the EV button again to switch back to HV mode.

Some conditions, such as a low High Voltage battery level and a

high vehicle speed, may keep the system from manually switching

into EV mode. The beeper sounds and a message appears on the

driver information interface with the button pressed when EV

mode is disabled.

Shifts in vehicle, driving, or road conditions may automatically

cancel EV mode and switch back to HV mode.

A message will appear on the driver information interface and EV mode may be canceled automatically when:

● The High Voltage battery charge level is low.

● Your vehicle speed is too high.

● Your vehicle speed is above 25 mph (40 km/h) while the engine is in warming-up operation.

● You fully depress the accelerator pedal.

● You are driving on hilly road.

● Regenerative Energy and Regenerative Braking

When regenerative braking is in

operation

When 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.

● 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 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 unusual noise should one develop.

After shutting off the engine, 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.

Safety Precautions

Do not touch the High Voltage system

Attempting 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 High 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.

uThe 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 contact 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.

Do not cover the air intake.

● Use a fire extinguisher for an electrical fire.

uAttempting 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.

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.

16

Emergency Shutdown System for the High Voltage System

If the vehicle is involved in a crash, the emergency 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.
