Floor mat installation
Insert the retaining hooks (clips) into
the floor mat eyelets.
Turn the upper knob of each retaining
hook (clip) to secure the floor mats in
place.
*: Always align the marks.
The shape of the retaining hooks (clips) may differ from that shown in the illustration.
Use only floor mats designed specifically for vehicles of the same model and model year
as your vehicle. Fix them securely in place onto the carpet.

Hybrid System
■Hybrid System Indicator
Your vehicle is a hybrid vehicle. It has characteristics different from conventional vehicles.
Be sure you are closely familiar with the characteristics of your vehicle, and operate it
with care.
The hybrid system combines the use of a gasoline engine and an electric motor (traction
motor) according to driving conditions, improving fuel efficiency and reducing exhaust
emissions.
For details, refer to the “OWNER’S MANUAL”.
Except F SPORT models F SPORT models

●Hybrid System Indicator is displayed when the driving mode is other than the sport
mode.
●By keeping the indicator needle within Eco area, more Eco-friendly driving can be
achieved.
●Charge area indicates regeneration
* status. Regenerated energy will be used to charge
the battery.
*: When used in this manual, “regeneration” refers to the conversion of energy created by
the movement of the vehicle into electrical energy.Charge area
Shows regenerative charging.
Hybrid Eco area
Shows that gasoline engine power is not being used very often.
The gasoline engine will automatically stop and restart under various conditions.
Eco area
Shows that the vehicle is being driven in an Eco-friendly manner.
Power area
Shows that an Eco-friendly driving range is being exceeded (during full power driving
etc.)

■Charging the hybrid battery (traction battery)
If the shift lever is in N, the hybrid battery (traction battery) will not be charged even when
the engine is running. Therefore, if the vehicle is left with the shift lever in N for a long period
of time, the hybrid battery (traction battery) will discharge, and this may result in the vehicle
not being able to start.
■Regenerative braking
In the following situations, kinetic energy is converted to electric energy and deceleration
force can be obtained in conjunction with the recharging of the hybrid battery (traction bat-
tery).
●The accelerator pedal is released while driving with the shift lever in D or S.
●The brake pedal is depressed while driving with the shift lever in D or S.
■Sounds and vibrations specific to a hybrid vehicle
There may be no engine sound or vibration even though the vehicle is able to move with the
“READY” indicator is illuminated. For safety, apply the parking brake and make sure to shift
the shift lever to P when parked.
The following sounds or vibrations may occur when the hybrid system is operating and are
not a malfunction:
●Motor sounds may be heard from the engine compartment.
●Sounds may be heard from the hybrid battery (traction battery) behind the rear seats
when the hybrid system starts or stops.
●Relay operating sounds such as a snap or soft clank will be emitted from the hybrid bat-
tery (traction battery), behind the rear seats, when the hybrid system is started or
stopped.
●Sounds from the hybrid system may be heard when the trunk lid is open.
●Sounds may be heard from the transmission when the gasoline engine starts or stops,
when driving at low speeds, or during idling.
●Engine sounds may be heard when accelerating sharply.
●Sounds may be heard due to regenerative braking when the brake pedal is depressed or
as the accelerator pedal is released.
●Vibration may be felt when the gasoline engine starts or stops.
●Cooling fan sounds may be heard from the air intake vents on the both sides of the rear
seatback.
■Running out of fuel
When the vehicle has run out of fuel and the hybrid system cannot be started, refuel the
vehicle with at least enough gasoline to make the low fuel level warning light go off. If there is
only a small amount of fuel, the hybrid system may not be able to start. (The standard amount
of fuel is about 2.6 gal. [10.0 L, 2.2 Imp.gal.] [except F SPORT models] or 2.6 gal. [9.9 L,
2.2 Imp.gal.] [F SPORT models], when the vehicle is on a level surface. This value may vary
when the vehicle is on a slope. Add extra fuel when the vehicle is inclined.)

■Hybrid warning message
A message is automatically displayed when a malfunction occurs in the hybrid system or an
improper operation is attempted.
If a warning message is shown on the multi-
information display, read the message and
follow the instructions.

Energy Monitor/Consumption Screen
■Energy monitor
●How to display on the Remote Touch screen
Press the “MENU” button on the Remote Touch, then select on the “Menu”
screen, and then select “Fuel Consumption”.
If the “Trip Information” or “Past Record” screen is displayed, select “Energy”.
●How to display on the multi-information display
Press or of the meter control switches and select , and then press or to
select the energy monitor display.
You can view the status of your hybrid system on the multi-information display and the
Remote Touch screen.
The energy monitor or consumption screen can be displayed on the side display.
The flow of energy is displayed on the Remote Touch screen.
Red: gasoline energy
Amber: electrical energy
Light blue: energy recovery
A light blue arrow appears when regenerative braking
occurs.
The flow of energy is indicated by the movement of the
arrows on the multi-information display.
Red: gasoline energy
Amber: electrical energy
Light blue: energy recovery
A light blue arrow appears when regenerative braking
occurs.
The displayed energy flow, battery level, etc. will change in response to the current driving
conditions.
