Plug-in hybrid system
Hybrid battery (traction battery) charge mode (→P. 83)
Electricity generated in the gasoline engine can be charged in the
hybrid battery (traction battery) by switching to the hybrid battery
(traction battery) charge mode when electricity needed for EV driv-
ing is not remaining.
*
● The system may not be able to swit ch to the hybrid battery (trac-
tion battery) charge mode due to the state of the plug-in hybrid
system. ( →P. 8 3 )
● Charging time differs depending on the driving state of the vehi-
cle when driving in hybrid battery (traction battery) charge mode.
When in the hybrid battery (traction battery) charge mode, the hybrid
battery charge mode indicator illuminates.
*: When in the hybrid battery (traction battery) charge mode, the hybrid battery can be charged while driving. However, the gasoline engine runs
to charge the battery and fuel consumption becomes higher compared
with driving in HV mode.

■When braking (regenerative braking)
The electric motor (traction motor) charges the hybrid battery (trac-
tion battery).
The EV driving range can be extend ed by actively using this regen-
erative braking to store electricity in the hybrid battery (traction bat-
tery).
Moreover, as fuel consumption is also reduced when in HV mode,
the regenerative braking system can be used effectively.
In order to make EV/EV auto
mode available, charge the hybrid
battery (traction battery) from an
external power source before
using the vehicle.
Even if charging the hybrid battery
(traction battery) has not been
completed, the vehicle can be
driven. However, if there is not
enough charge remaining, it is pos-
sible that the vehicle cannot be
driven in EV/EV auto mode or the
EV driving range will become
shorter.
When driving with the gasoline engine stopped, a sound, which
changes in accordance with the driving speed, will be played in order
to warn people nearby of the vehi cle’s approach. The sound will stop
when the vehicle speed exceeds approximately 15 mph (25 km/h).

Plug-in hybrid vehicle driving tips
◆Using EV mode and HV mode effectively
Primarily using EV mode when driving in cities and using HV mode
when driving on highways (or freeways) can help conserve fuel and
electricity. ( →P. 8 2 )
◆Using Eco drive mode
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 (h eating/cooling) will be minimized, improving
fuel and electricity economy. ( →P. 406)
◆Use of Hybrid System Indicator
Eco-friendly driving is possible by keeping the Hybrid System Indi-
cator within Eco area. ( →P. 210)
◆Shift position operation
Shift the shift position to D when st opped at a traffic light, or driving
in heavy traffic etc. Shift the sh ift position to P when parking. When
using the N, there is no positive effect on fuel consumption. In the
N, the gasoline engine operates but electricity cannot be gener-
ated. Also, when using the air cond itioning system, etc., the hybrid
battery (traction batter y) power is consumed.
For economical and ecological driv ing, pay attention to the fol-
lowing points:

2-1. Plug-in hybrid system
◆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)
*1: Vehicles with 7-inch display
*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.

The power switch is in ON mode.
■ Adjusting the instrument cluster brightness (→P. 182)
● The brightness levels that can be selected differ depending on whether the
tail lights are on and surrounding brightness levels, as shown in the table
below.
*: 22 levels of the brightness are displayed on the setting screen. However,
the brightness setting will be the brightest when other than 1st level (the
darkest) is selected. If other than 1st or 22nd level is selected, when the
tail lights are turned on in a dark place, the instrument cluster brightness
setting will be the selected level.
● If the taillights are illuminated in a dark environment, the instrument cluster
light dims. However, when the brightness of the instrument cluster is set to
minimum or maximum (1st or 22nd level of the instrument cluster bright-
ness), even if the taillights are illuminated, the instrument cluster light will
not dim.
