◆Accelerator pedal/brake pedal operation
●Drive your vehicle smoothly. Avoid abrupt acceleration and
deceleration. Gradual accelerati on 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 consumes
hybrid battery (traction battery) power, resulting in poor fuel con-
sumption. Battery power can be restored by driving with the
accelerator pedal slightly released.
◆When braking
Make sure to operate the brakes gently and a timely manner. A
greater amount of electrical energy can be regenerated when slow-
ing down.
◆Delays
Repeated acceleration and deceleration, as well as long waits at
traffic lights, will lead to high fuel and electricity consumption.
Check traffic reports before leav ing and avoid delays as much as
possible. When driving in a traffi c jam, gently release the brake
pedal to allow the vehicle to move forward slightly while avoiding
overuse of the accelerator pedal. Doing so can help control exces-
sive electricity and fuel consumption.
◆Highway driving
● Control and maintain the vehicl e at a constant speed. Before
stopping at a toll booth or similar, allow plenty of time to release
the accelerator and gently apply the brakes. A greater amount of
electrical energy can be regenerated when slowing down.
● Electricity consumption will increa se significantly when driving at
high speeds in EV mode. If there will be a long distance to the
next external charging point after leaving a freeway, it is recom-
mended to drive in HV mode while on the freeway and change to
EV mode after leaving the freeway.

◆Air conditioning
●Turn the “A/C” switch (
*1 • *2) off when it is
not needed. Doing so can help r educe excessive electricity and
fuel consumption.
In summer: When the ambient temperature is high, use the recir-
culated air mode. Doing so will he lp to reduce the burden on the
air conditioning system and reduc e electricity and fuel consump-
tion as well.
In winter: Avoid excessive and unn ecessary use of the heater.
Usage of the heated steering wheel (if equipped) and seat heat-
ers is effective. ( →P. 513)
● Using the Remote Air Conditioning System (→P. 509) while the
charging cable is connected to th e vehicle can reduce electricity
consumption immediately after starting off by operating air condi-
tioning mainly using electricity from an external power source.
● When setting the timer, selecting the start time setting mode and
setting “Climate Prep” to “On” can reduce electricity consumption
immediately after starting off by operating air conditioning before
charging is completed. ( →P. 147)

*2: Vehicles with 11.6-inch display
◆Checking tire inflation pressure
Make sure to check the tire infl ation pressure frequently. If there is
improper tire inflation pressure in the tires, the EV driving range will
become shorter, and fuel c onsumption when in HV mode will
increase.
Also, as snow tires can cause larg e amounts of friction, their use on
dry roads can lead to increased fuel and electricity consumption.
◆Luggage
Carrying heavy luggage will lead to poor fuel economy. Avoid carry-
ing unnecessary luggage. Installing a large roof rack will also cause
poor fuel economy.
◆Warming up before driving
Since the gasoline engine starts up and cuts out automatically,
warming up is not necessary.

EV driving range
The value displayed on the multi-information display etc. (→P. 199,
215, 222, 239) is estimated from the following information.
● The amount of hybrid battery (traction battery) charge currently
remaining
● The electricity consumption (the estimated distance that can be
driven in EV mode per unit of electrical energy) based on the
recorded value
● Past air conditioning system electricity consumption amount
The electricity consum ption varies depending on how the vehicle is
driven. The vehicle automatically re cords the electricity consumption
when being charged and uses the el ectricity consumption for estimat-
ing the EV driving range. Therefor e, the EV driving range displayed
when the hybrid battery (traction ba ttery) is fully charged may differ
from the previous EV driving range depending on how the vehicle was
driven.
The EV driving range may change si gnificantly with each charging
until the electricity consumption based on the recorded value is stable
(for approximately the fi rst month or two). However, this does not indi-
cate a malfunction.
When the air conditioning system is turned on, the EV driving range
(with using the air conditioning syst em) is estimated based on the past
air conditioning electricity consumption amount considering that the
electricity consumpt ion may become higher.
The EV driving range displayed on the multi-information display
etc. shows the reference distance that EV driving (driving using
only the electric motor) is possible, and the actual distance that
can be driven may differ from that displayed.
Even if the EV driving range is displayed, EV driving may be can-
celed and both gasoline engine and electric motor are used depend-
ing on the situation. ( →P. 8 7 )

Charging methods
◆Charging from an external power source (→P. 136)
This is a charging method used when charging from an AC outlet
(120 V) with the charging cable equ ipped to the vehicle or charging
at a public charging station.
The charging start time (or departure time) and day can be set to carry
out charging using the timer at the desired date and time. (→P. 147)
◆Using the hybrid battery (tra ction battery) charge mode
(→ P. 81)
The plug-in hybrid system can be switched to hybrid battery (trac-
tion battery) charge mode to charge the hybrid battery (traction bat-
tery) using electricity generat ed by gasoline engine operation.
The maximum charge amount in the hybrid battery (traction battery)
charge mode is approximately 80% of the fully charged capacity for the
charging from an external power source.
The time required to charge the hybr id battery (traction battery) differs
according to the charging voltage and charging current.
*1: This is the maximum value. Furthermore, the upper limit of the charging current can be changed in the “Vehicle Settings” settings. ( →P. 123)
*2: The time required for charging to complete depends on conditions such as
the remaining charge of the hybrid battery (traction battery) and the outside
temperature.
The following methods can be used to charge the hybrid battery
(traction battery).

■BSM (Blind Spot Monitor) outsid e rear view mirror indicators
(if equipped) ( →P. 408)
• When the BSM function is enabled on the screen of the multi-infor- mation display, the power switch is turned to ON mode.
If the system is functioning correctly, the BSM outside rear view mirror indi-
cators will turn off after a few seconds.
If the BSM outside rear view mirror indicators do not illuminate or do not
turn off, there may be a malfunction in the system.
If this occurs, have the vehicle inspected by your Toyota dealer.
●
Indicators are also displayed on the out-
side rear view mirrors.
● In order to confirm operation, the BSM
outside rear view mirror indicators illumi-
nate in the following situations:
• When the power switch is in ON
mode, the BSM function is enabled
on the screen of the multi-infor-
mation display.
WARNING
■If a safety system warning light does not come on
Should a safety system light such as the ABS and SRS warning light not
come on when you start the hybrid system, this could mean that these sys-
tems are not available to help protect you in an accident, which could r\
esult
in death or serious injury. Have the vehicle inspected by your Toyota dealer
immediately if this occurs.
NOTICE
■To prevent damage to the engine and its components
The engine may be overheating if the high coolant temperature warning
light comes on or flashes. In this case, immediately stop the vehicle in a
safe place, and check the engine after it has cooled completely. ( →P. 700)

◆Energy monitor
The energy monitor can be used to check the vehicle drive status,
hybrid system operation status and energy regeneration status.
While charging from the external pow er source, the flow of electrical
energy while charging is displayed.
When energy is flowing, an arrow appears and a bright point of light
moves to show the direction of the flow of energy. When energy is
not flowing, the bright point of light is not displayed.
● The arrows from the image of the engine to that of the electric
motor (traction motor) or tires are displayed in red.
● The arrow indicating energy consumption is displayed in yellow,
and the arrow indicating energy regeneration or charging is dis-
played in green. Also, the colo r around the image of the hybrid
battery (traction battery) is changed.
As an example, all arrows are shown in the illustration, but the actual
contents of the display will differ.
