NOTICE
■Notice about fuel
●For Plug-in Hybrid Electric Vehi-
cles, fuel may remain in the tank for a long time and undergo changes in quality depending on the how the
vehicle is used. Refuel at least 20 L (5.3 gal., 4.4 Imp.gal.) of fuel every 12 months (refuel a total of at least
20 L [5.3 gal., 4.4 Imp.gal.] over a 12-month period), as this may affect components of the fuel sys-
tem or the gasoline engine.
●If the vehicle has not been refueled
for a certain amount of time and it is possible that the quality of the fuel remaining in the tank has changed,
“No New Fuel has been Added Recently Please refuel” is displayed on the multi-information display
when the power switch is turned to ON. If the message is displayed, refuel the vehicle immediately.

NOTICE
■DC/DC converter air intake vent
●Make sure not to block the air
intake vent with anything, such as a seat cover, plastic cover, or lug-gage. Blocking the air intake vent
may prevent the plug-in hybrid sys- tem from operating properly.
●When dust etc. has accumulated in the air intake vent, clean it with a vacuum cleaner to prevent the vent
from clogging.
●Do not wet or allow foreign sub-
stances to enter the air vent as this may cause a short circuit and dam-age the DC/DC converter.
●Do not carry large amounts of water such as water cooler bottles in the
vehicle. If water spills onto the DC/DC converter, the converter may be damaged. Have the vehicle
inspected by any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●A filter is installed to the air intake vent. When the filter remains
noticeably dirty even after cleaning the air intake vent, filter cleaning or replacement is recommended.
When cleaning the filter, refer to P.504.

Primarily using EV mode and
AUTO EV/HV mode when driving in
cities and using HV mode when
driving on highways (or freeways)
can help conserve fuel and electric-
ity. (P.86)
When using Eco drive mode, the
torque corresponding to the accel-
erator pedal depression amount
can be generated more smoothly
than it is in normal conditions. In
addition, the operation of the air
conditioning system (heating/cool-
ing) will be minimized, improving
fuel and electricity economy.

The value displayed on the SOC
(State of Charge) gauge (P.187,
193) 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 driv-
ing is possible per unit of electri-
cal energy) based on the
recorded value
Past air conditioning system
electricity consumption amount
The electricity consumption varies
depending on how the vehicle is
driven. The vehicle automatically
records the electricity consumption
when being charged and uses the electricity consumption for estimat-
ing the EV driving range. Therefore,
the EV driving range displayed
when the hybrid battery (traction
battery) is fully charged may differ
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 consumption
based on the recorded value is sta-
ble (for approximately the first
month or two). However, this does
not indicate a malfunction.
When the air conditioning system is
turned on, the EV driving range
(with using the air conditioning sys-
tem) is estimated based on the past
air conditioning electricity con-
sumption amount considering that
the electricity consumption may
become higher.
The distance that EV driving is pos-
sible varies significantly depending
on how the vehicle is driven, road
conditions, the weather, the outside
temperature, usage conditions of
electrical components and the num-
ber of occupants.
The distance that EV driving is pos-
sible can be extended if the follow-
ing is performed:
EV driving range
The EV driving range displayed
on the multi-information dis-
play shows the reference dis-
tance that EV driving (driving
using only the electric motor)
is possible, and the actual dis-
tance that can be driven may
differ from that displayed.
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 situation.

■When starting off, depress the
accelerator pedal smoothly to
accelerate
As a guide, accelerate up to
approximately 20 km/h (12mph) in
the first 5 seconds.
Electrical and fuel efficiency can be
improved just by using the ECO
Accelerator Guidance displayed on
the multi-information display and
taking care to start off gently.
(P.202)
When the driving mode is set to Eco
drive mode, depressing the accelerator
pedal generates smooth torque that
makes it easier to operate the accelera-
tor gently.
■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.
■Release the accelerator pedal
early before stopping the vehi-
cle, such as at a traffic light
The regenerative brake will operate
to convert the kinetic energy of the
vehicle into electrical energy, which
will charge the hybrid battery (trac-
tion battery).
The regeneration status can be
checked from the Hybrid System
Indicator. (P.190)When the brake pedal is depressed
lightly during deceleration, the
regeneration amount increases,
enabling more electrical energy to
be recovered.
If the brake pedal is depressed too
strongly, the recovered amount indica-
tor will reach the maximum level and
the upper limit of the recoverable
energy will be exceeded. Therefore, be
sure to operate the brake pedal early.
■Use the air conditioning sys-
tem appropriately, and also
utilize the heated steering
wheel (if equipped) and seat
heaters
In EV mode, the vehicle is cooled
and heated by electrical energy.
(Except in extremely cold tempera-
tures of approximately -10°C (14°F)
or less.)
Preventing excessive cooling or
heating of the vehicle will reduce
power consumption and improve
electrical efficiency.
The heated steering wheel (if
equipped) and seat heaters are effi-
cient heating device that directly
warm the body using less electric
power.
When used together with the air condi-
tioning system, a low temperature set-
ting can be used to improve electrical
and fuel efficiency.
■Check the tire pressure
If the tire pressure is lower than the
specified value, it will worsen the
electrical and fuel efficiency.

Plug-in hybrid system
A pressure level 50 kPa (0.5 kgf/cm2 or
bar, 7 psi) lower than the specified
value will cause a worsening of several
percentage points.
■When driving on highways,
use the EV/HV mode selection
switch to drive in HV mode
The power consumption will
increase significantly if the vehicle
is driven in EV mode on highways.
■Do not load unnecessary
objects in the vehicle
Driving with objects weighing 100
kg (220 lb.) in the vehicle will
worsen the electrical and fuel effi-
ciency by approximately 3%.
Air resistance also greatly affects
electrical and fuel efficiency.
Remove any exterior accessories
such as a roof luggage 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 longer
needed.
■Know your vehicle’s electrical
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 Consumption/Fuel
Economy, ECO Accelerator Guid-
ance/“Eco Score” and other data
displayed on the multi-information display.
