Quick Reference Guide
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 elec tric 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, p ressing the e
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 engin e.
In addition, heavy climate control system us e negatively affects vehicle range and efficiency. Either of these use patterns wil l more quickly
reduce the High Voltage battery's state of charge.
●Battery types
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.

Quick Reference Guide
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.

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.

Safe Driving
Exhaust Gas Hazard
Carbon Monoxide Gas
The engine exhaust from this vehicle contains carbon monoxide, a colorless,
odorless, and highly toxic gas. As long as you properly maintain your vehicle, carbon
monoxide gas will not get into the interior.
■Have the exhaust system in spected for leaks whenever
• The exhaust system is ma king an unusual noise.
• The exhaust system may have been damaged.
• The vehicle is raised for an oil change.
When you operate a vehicle with the trunk open, airflow can pull exhaust gas into
the interior and create a hazardous condition. If you must drive with the trunk open,
open all the windows and set the climate control system as shown below.
1. Select the fresh air mode.
2. Select the mode.
3. Set the fan speed to high.
4. Set the temperature control to a comfortable setting.
Adjust the climate control system in the same manner if you sit in your parked
vehicle with the engine running.
1 Carbon Monoxide Gas
An enclosed area such as a garage can quickly fill up
with carbon monoxide gas.
Do not run the engine with the garage door closed.
Even when the garage door is open, drive out of the
garage immediately afte r starting the engine.
3WARNING
Carbon monoxide gas is toxic.
Breathing it can cause unconsciousness and
even kill you.
Avoid any enclosed areas or activities that
expose you to carbon monoxide.
