◆Air conditioning
●Turn the “A/C” switch (
*1 • *2) 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 heated steering wheel (if equipped) and seat heat-
ers is effective. (P. 5 3 9 )
●Using the Remote Air Conditioning System (P. 535) 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. (P. 157)
*1: Vehicles with 7-inch display
*2: Vehicles with 11.6-inch display
◆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.
◆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.

Operation of each component
Auto anti-glare inside rear view mirror
Responding to the level of brightness of the headlights of vehicles
behind, the reflected light is automatically reduced.
Changing automatic anti-glare
function mode
On/off
When the automatic anti-glare
function is in ON mode, the indica-
tor illuminates.
The function will set to ON mode
each time the power switch is
turned to ON mode.
Pressing the button turns the func-
tion to OFF mode. (The indicator
also turns off.)
■To prevent sensor error (vehicles with auto anti-glare inside rear view
mirror)
Indicator
To ensure that the sensors operate prop-
erly, do not touch or cover them.
WARNING
Do not adjust the position of the mirror while driving.
Doing so may lead to mishandling of the vehicle and cause an accident,
resulting in death or serious injury.

Operation of each component
■Mirror angle can be adjusted when
The power switch is in ACCESSORY or ON mode.
■When the mirrors are fogged up
The outside rear view mirrors can be cleared using the mirror defoggers. Turn
on the rear window defogger to turn on the outside rear view mirror defog-
gers. (P. 516, 527)
WARNING
■Important points while driving
Observe the following precautions while driving.
Failing to do so may result in loss of control of the vehicle and cause an
accident, resulting in death or serious injury.
●Do not adjust the mirrors while driving.
●Do not drive with the mirrors folded.
●Both the driver and passenger side mirrors must be extended and properly
adjusted before driving.
■When a mirror is moving
To avoid personal injury and mirror malfunction, be careful not to get your
hand caught by the moving mirror.
■When the mirror defoggers are operating
Do not touch the rear view mirror surfaces, as they can become very hot
and burn you.

Driving
Stop the vehicle completely.
Set the parking brake. (P. 3 5 2 )
Shift the shift position to P. (P. 346)
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. 502)
■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. 105).
■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.

5-1. Before driving
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When starting the vehicle
Always keep your foot on the brake pedal while stopped with the “READY”
indicator is illuminated. This prevents the vehicle from creeping.
■When driving the vehicle
●Do not drive if you are unfamiliar with the location of the brake and accel-
erator pedals to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the brake
pedal will result in sudden acceleration that may lead to an accident.
• When backing up, you may twist your body around, leading to a diffi-
culty in operating the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving posture even when moving the
vehicle only slightly. This allows you to depress the brake and accelera-
tor pedals properly.
• Depress the brake pedal using your right foot. Depressing the brake
pedal using your left foot may delay response in an emergency, result-
ing in an accident.
●The driver should pay extra attention to pedestrians when the vehicle is
powered only by the electric motor (traction motor). As there is no engine
noise, the pedestrians may misjudge the vehicle’s movement. Even
though the vehicle is equipped with the vehicle proximity notification sys-
tem, drive with care as pedestrians in the vicinity may still not notice the
vehicle if the surrounding area is noisy.
●Do not drive the vehicle over or stop the vehicle near flammable materials
such as leaves, paper or rags.
The exhaust system and exhaust gases can be extremely hot. These hot
parts may cause a fire if there is any flammable material nearby.
●During normal driving, do not turn off the hybrid system. Turning the hybrid
system off while driving will not cause loss of steering or braking control,
however, power assist to the steering will be lost. This will make it more
difficult to steer smoothly, so you should pull over and stop the vehicle as
soon as it is safe to do so.
In the event of an emergency, such as if it becomes impossible to stop the
vehicle in the normal way: P. 665

●Do not use the accelerator pedal or depress the accelerator and brake
pedals at the same time to hold the vehicle on a hill.
■When parking the vehicle
Always set the parking brake, and shift the shift position to P. Failure to do
so may cause the vehicle to move or the vehicle may accelerate suddenly if
the accelerator pedal is accidentally depressed.
■Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in either direction and hold it there for
an extended period of time.
Doing so may damage the power steering motor.
●When driving over bumps in the road, drive as slowly as possible to avoid
damaging the wheels, underside of the vehicle, etc.
■If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering
wheel firmly and gradually depress the brake pedal to slow down the vehi-
cle.
●It may be difficult to control your vehicle.
●The vehicle will make abnormal sounds or vibrations.
●The vehicle will lean abnormally.
