◆Air conditioning
●Turn the “A/C” switch ( ) off when it is not needed. Doing
so can help reduce excessive electricity and fuel consumption.
In summer: When the ambient temperature is high, use the recir-
culated air mode. Doing so will help to reduce the burden on the
air conditioning system and reduce electricity and fuel consump-
tion as well.
In winter: Avoid excessive and unnecessary use of the heater.
Usage of the seat heaters is effective. (P. 589)
●Using the Remote Air Conditioning System (P. 585) while the
charging cable is connected to the 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 charging schedule, selecting the start time set-
ting mode and setting “Climate Prep” to “On” can reduce electric-
ity consumption immediately after starting off by operating air
conditioning before charging is completed. (if equipped)
(P. 176)
◆Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently. If there is
improper tire inflation pressure in the tires, the EV driving range will
become shorter, and fuel consumption when in HV mode will
increase.
Also, as snow tires can cause large amounts of friction, their use on
dry roads can lead to increased fuel and electricity consumption.

The distance that can be driven in EV mode varies significantly
depending on how the vehicle is driven, road conditions, the weather,
the outside temperature, usage conditions of electrical components
and the number of occupants.
The distance that can be driven in EV mode can be extended if the fol-
lowing is performed:
●Maintain a safe distance from the vehicle in front and avoid unnec-
essary acceleration and deceleration
●Accelerate and decelerate the vehicle as smoothly as possible
●Drive at moderate speeds as much as possible and maintain a con-
stant speed
●
Set the air conditioning to a moderate temperature and turn the “A/C”
switch ( ) off when it is not needed
●Use tires of the specified size and maintain the specified tire pres-
sure
●Use the EV/HV mode selection switch to drive in HV mode when
driving on a highway
Electricity consumption will increase substantially when driving on a
highway in EV mode.
●Do not add unnecessary weight to the vehicle
The following indicate that charging has been carried out properly.
●The charging indicator turns off
●The Hybrid battery (traction battery) status indicators illuminate for
approximately 15 seconds. (P. 123)
●“Charging Complete” is displayed on the multi-information display
when starting off (P. 159)
Regardless of the type of power source or whether the charging
schedule function is used, charging is completed if the above can be
confirmed.

◆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 power source, the flow of electrical
energy while charging is displayed.
On vehicles with solar charging system, the approximate power genera-
tion level is also 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 color 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.

3595-1. Before driving

Driving
Stop the vehicle completely.
Set the parking brake. (P. 386)
Shift the shift position to P. (P. 380)
Check that the shift position indicator shows P.
Press the power switch to stop the hybrid system.
Slowly release the brake pedal.
Lock the door, making sure that you have the electronic key on your
person.
If parking on a hill, block the wheels as needed.
Firmly set the parking brake with the brake pedal depressed, and
then shift the shift position to D.
Release the brake pedal and gently depress the accelerator pedal.
Release the parking brake.
■When starting off on an uphill
The hill-start assist control will activate. (P. 559)
■For electricity-saving and fuel-efficient driving
Understand the system characteristics of the vehicle to use the functions of
the hybrid system. Also, keep in mind that hybrid vehicles are similar to con-
ventional vehicles, and it is necessary to refrain from activities such as sud-
den acceleration. Refer to “Plug-in hybrid vehicle driving tips” (P. 115).
■Driving in the rain
●Drive carefully when it is raining, because visibility will be reduced, the win-
dows may become fogged-up, and the road will be slippery.
●Drive carefully when it starts to rain, because the road surface will be espe-
cially slippery.
●Refrain from high speeds when driving on an expressway in the rain,
because there may be a layer of water between the tires and the road sur-
face, preventing the steering and brakes from operating properly.

WARNING
■ When to disable the pre-collision system
In the following situations, disable the system, as it may not operate prop-
erly, possibly leading to an accident resulting in death or serious injury:
● When the vehicle is being towed
● When your vehicle is towing another vehicle
● When transporting the vehicle via truck, boat, train or similar means of
transportation
● When the vehicle is raised on a lift with the hybrid system on and the tires
are allowed to rotate freely
● When inspecting the vehicle using a drum tester such as a chassis
dynamometer or speedometer tester , or when using an on vehicle wheel
balancer
● When a strong impact is applied to the front bumper or front grille, due to
an accident or other reasons
● If the vehicle cannot be driven in a stable manner, such as when the vehi-
cle has been in an accident or is malfunctioning
● When the vehicle is driven in a sporty manner or off-road
● When the tires are not properly inflated
● When the tires are very worn
● When tires of a size other than specified are installed
● When tire chains are installed
● When a compact spare tire or an emergency tire puncture repair kit is used
● If equipment (snow plow, etc.) that may obstruct the radar sensor or front
camera is temporarily installed to the vehicle
