10Quick 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 moto r
receiving electricity from an internal High Voltage battery or internal generator. The High Voltage battery can be 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 combinat ion of two. The
system selects which propulsion source is most appropriate and automatically switches to it. Under certain circumstances, press ing 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. Ag gressive
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 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 st andard 12-volt battery that powers the airbags, the interior and ext erior 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 COMPONENTSGasoline Engine
– Provides propulsion to drive the wheels
under certain driving conditions, and turns the generator.
Generator
– Starts the engine and generates electric power
when driven by the gasoline engine to supply electricity to
power the electric motor and/o r 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 Vol tage 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. (P455)
High Voltage Battery Charge Level Indicator
– Displays
battery state of charge.
When the indicator:
•Displays two or less segments, EV mo de is no longer available.•Displays eight segments, battery charge level is full.

●Regenerative Energy and Regenerative Braking
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. This function is
enhanced when the shift lever is moved to .
● 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 po wer 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.
● Sounds Unique to the SPORT HYBRID i-MMD System
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 automob iles 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.When regenerative braking is in

Maintenance
(P 467)
Under the Hood
(P 475)
● Check engine oil, engine coolant, inverter coolant, and
windshield washer fluid. Add when necessary.
● Check brake fluid.
● Check the 12-volt battery condition monthly.
a
Pull the hood release handle under the corner of the
dashboard.
b
Locate the hood latch lever, pull the lever up, and lift up
the hood.
c
When finished, close the hood and make sure it is firmly
locked in place.
Lights
(P 488)
● Inspect all lights regularly.
Wiper Blades
(P 495)
● Replace blades if they leave streaks
across the windshield.
Tires
(P 497)
● Inspect tires and wheels regularly.
● Check tire pressures regularly.
● Install snow tires for winter
driving.

70Safe Driving
Exhaust Gas HazardCarbon Monoxide GasThe 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 inspected for leaks whenever
• The exhaust system is making 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.
1Carbon Monoxide Gas
An enclosed area such as a garage can quickly fill up
with carbon monoxide gas.
Do not turn the power system on with the garage
door closed. Even when the garage door is open,
drive out of the garage immediately after turning the
power system on.
3
WARNING
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.
