882-1. Plug-in hybrid system
Primarily using EV mode and
AUTO EV/HV mode when driv-
ing in cities and using HV mode
when driving on highways (or
freeways) can help conserve
fuel and electricity. (P.74)
When using Eco drive mode, the
torque corresponding to the
accelerator pedal depression
amount can be generated more
smoothly than it is in normal
conditions. In addition, the oper-
ation of the air conditioning sys-
tem (heating/cooling) will be
minimized, improving fuel and
electricity economy. ( P.422)
Eco-friendly driving is possible
by keeping the Hybrid System
Indicator within Eco area.
( P.158) Shift the shift position to D when
stopped at a traffic light, or driv-
ing in heavy traffic etc. Shift the
shift position to P when parking.
When using the N, there is no
positive effect on fuel consump-
tion. In the N, the gasoline
engine operates but electricity
cannot be generated. Also,
when using the air conditioning
system, etc., the hybrid battery
(traction battery) power is con-
sumed.

Drive your vehicle smoothly.
Avoid abrupt acceleration and
deceleration. Gradual accel-
eration and deceleration will
make more effective use of
the electric motor (traction
motor) without having to use
gasoline engine power.
 Avoid repeated acceleration.
Repeated acceleration con-
sumes hybrid battery (trac-
tion battery) po wer, resulting
in poor fuel consumption. Bat-
tery power can be restored by
driving with the accelerator
pedal slightly released.
Make sure to operate the brakes

For economical and ecolog-
ical driving, pay attention to
the following points:
Using EV mode, AUTO
EV/HV mode and HV
mode effectively

■Release the accelerator
pedal early before stopping
the vehicle, such as at a
traffic light
The regenerative brake will
operate to convert the kinetic
energy of the vehicle into electri-
cal energy, which will charge the
hybrid battery (traction battery).
The regeneration status can be
checked from the Hybrid Sys-
tem Indicator. ( P.158)
When the brake pedal is
depressed lightly during decel-
eration, the regeneration
amount increases, enabling
more electrical energy to be
recovered.
If the brake pedal is depressed too
strongly, the recovered amount
indicator will reach the maximum
level and the upper limit of the
recoverable en ergy will be
exceeded. Therefore, be sure to
operate the brake pedal early.
■Use the air conditioning
system appropriately, and
also utilize the heated steer-
ing wheel (if equipped) and
seat heaters (if equipped)
In EV mode, the vehicle is
cooled and heated by electrical
energy. (Except in extremely
cold temperatures of approxi-
mately 14°F [-10°C] or less.)
Preventing excessive cooling or
heating of the vehicle will reduce
power consumption and
improve electrical efficiency. When eco air conditioning mode
is used, the air conditioning con-
trol is switched automatically to
a lower setting. (
P.437)
The heated steering wheel and
seat heaters are efficient heat-
ing device that directly warm the
body using less electric power.
When used together with the air
conditioning system, a low tem-
perature setting can be used to
improve electrical and fuel effi-
ciency.
■Check the tire pressure
If the tire pressure is lower than
the specified value, it will
worsen the electrical and fuel
efficiency.
A pressure level 7 psi (50 kPa, 0.5
kgf/cm
2 or bar) lower than the spec-
ified value will cause a worsening of
several percentage points.
■When driving on highways,
use the EV/HV mode selec-
tion switch to drive in HV
mode
The power consumption will
increase significantly if the vehi-
cle is driven in EV mode on
highways.
■Do not load unnecessary
objects in the vehicle
Driving with objects weighing
220 lb. (100 kg) in the vehicle
will worsen the electrical and
fuel efficiency by approximately
3%.
Air resistance also greatly

affects electrical and fuel effi-
ciency. Remove any exterior
accessories such as a roof lug-
gage carrier when they are not
being used.
The running resistance of snow
tires is high and they will worsen
electrical and fuel efficiency.
Replace them with standard
tires as soon as they are no lon-
ger needed.
■Know your vehicle’s electri-
cal and fuel efficiency
If you know your vehicle’s daily
electrical and fuel efficiency, you
will understand the benefits of
Eco drive.
Use the Power Consump-
tion/Fuel Economy, ECO Accel-
erator Guidance/“Eco Score”
and other data displayed on the
multi-information display.
The following indicate that
charging has been carried out
properly.
 The charging indicator of the
charging port turns off
 “Charging Complete” is dis-
played on the multi-informa-
tion display when a door is
opened with the power switch
off ( P.112)
Regardless of the type of power
source or whether the charging schedule function is used,
charging is completed if the
above can be confirmed.

Error warning indicator ( P.99)
The CCID (Charging Circuit
Interrupting Device) has the fol-
lowing safety features.
■Electrical leakage detec-
tion function
If an electrical leakage is
detected during charging, the
power source will be automati-
cally interrupted, thus prevent-
ing fires or electrical shocks
caused by electrical leakage.
If the power source is interrupted,
the error warning indicator flashes.
If the power source is interrupted:
 P.100
■Automatic check function
This is an automatic system
check that is run before
charging begins to check for
problems in the operation of the
electrical leakage detection
function.
If a malfunction is found in the elec-
trical leakage detection function as
a result of the check, the error
warning indicator flashes to inform
the user. ( P.100)
■Temperature detection
function
A temperature detection func-
tion is equipped to the plug.
While charging, if heat is gener-
ated due to looseness on the
outlet side etc., this function
suppresses heat by controlling
the charging current.
■Conditions for supplying
current to the vehicle
The CCID (Charging Circuit
Interrupting Device) is designed
to prevent electrical current from
being supplied to the charging
connector when it is not con-
nected to the vehicle, even if the
plug is inserted into the outlet.

■When a malfunction occurs during charging
The indicators on the CCID (Chargi ng Circuit Interrupting Device)
use a combination of different statuses (not illuminated, illuminated
or flashing) to inform the user of internal malfunctions.
When the error warning indicator is illuminated or flashing, temporarily
remove the plug from the outlet and th en reconnect it to check if the error
indicator turns off.
If the error warning indicator turns off, charging is now possible.
If it does not turn off, perform the correction procedure in the following
