Carrying heavy luggage will lead
to poor fuel economy. Avoid car-
rying unnecessary luggage.
Installing a large roof rack will
also cause poor fuel economy.
Since the gasoline engine starts
up and cuts out automatically,
warming up is not necessary.The value displayed on the SOC
(State of Charge) gauge
(P.155) is estimated from the
following information.
 The amount of hybrid battery
(traction battery) charge cur-
rently remaining
 The electricity consumption
(the estimated distance that
EV driving is possible per unit
of electrical energy) based on
the recorded value
 Past air conditioning system

EV driving range
The EV driving range dis-
played on the meter shows
the reference distance that
EV driving (driving using
only the electric motor) is
possible, and the actual dis-
tance that can be driven
may differ from that dis-
played.
Even if the EV driving range is
displayed, EV driving may be
canceled and both gasoline
engine and electric motor are
used depending on the situa-
tion. ( P.79)
Displayed value

912-1. Plug-in hybrid system
2
Plug-in hybrid system
automatically records the elec-
tricity consumption when being
charged and uses the electricity
consumption for estimating the
EV driving range. Therefore, the
EV driving range displayed
when the hybrid battery (traction
battery) is fully charged may dif-
fer from the previous EV driving
range depending on how the
vehicle was driven.
The EV driving range may
change significantly with each
charging until the electricity con-
sumption based on the recorded
value is stable (for approxi-
mately the first month or two).
However, this does not indicate
a malfunction.
When the air conditioning sys-
tem is turned on, the EV driving
range (with using the air condi-
tioning system) is estimated
based on the past air condition-
ing electricity consumption
amount considering that the
electricity consumption may
become higher.
The distance that EV driving is
possible varies significantly
depending on how the vehicle is
driven, road conditions, the
weather, the outside tempera-
ture, usage conditions of electri-
cal components and the number of occupants.
The distance that EV driving is
possible can be extended if the
following is performed:
■When starting off, depress
the accelerator pedal
smoothly to accelerate
As a guide, accelerate up to
approximately 12mph (20 km/h)
in the first 5 seconds.
Electrical and fuel efficiency can
be improved just by using the
ECO Accelerator Guidance dis-
played on the multi-information
display and taking care to start
off gently. ( P.163)
When the driving mode is set to
Eco drive mode, depressing the
accelerator pedal generates
smooth torque that makes it easier
to operate the accelerator gently.
At the same time, the air condition-
ing control is switched to eco air
conditioning mode ( P.437) to
reduce the strength of the air condi-
tioning operation.
■Maintain sufficient vehicle-
to-vehicle distance and do
not accelerate or decelerate
unnecessarily
Try to maintain a fixed speed
while driving. Driving at a short
vehicle-to-vehicle distance will
result in repeating wasteful
acceleration and deceleration,
which will worsen the electrical
and fuel efficiency.

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.

Also, if the hybrid battery (traction
battery) capacity reduces, the dis-
tance that can be driven in EV mode
or AUTO EV/HV mode decreases.
However, vehicle performance does
not significantly become worse.
■When the remaining charge of
the hybrid battery (traction bat-
tery) is low after charging
In the following situations, the
remaining charge of the hybrid bat-
tery (traction battery) after charging
completes may be less than normal
in order to protect the system (the
EV driving range after the hybrid
battery [traction battery] is fully
charged may be shorter).
*
●Charging is carried out when the
outside temperature is low or high.
●Charging is carried out immedi-
ately after high-load driving or in
extreme heat.
When none of the above situations
apply and there is a drastic drop in
the remaining charge of the hybrid
battery (traction battery) after
charging completes, have the vehi-
cle inspected by your Toyota dealer.
