■Highway driving
Control your speed and keep at a constant speed. Also, 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 retained when slowing down.
Electricity consumption will increase substantially 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, driving in
HV mode while on the freeway and in EV mode after leaving the
freeway is recommended.
■Air conditioning on/off
●Switch the air conditioning ( ) to off when it is not
needed. Doing so can help control excessive electricity and
fuel consumption.
In summer: In high temperatures, use the recirculated air
mode. Doing so will help to reduce the burden on the air con-
ditioner and reduce fuel consumption as well.
In winter: Because the gasoline engine will not automatically
cut out until the gasoline engine and the interior of the vehicle
are warm, it will consume fuel. Also, fuel consumption can be
improved by avoiding overuse of the heater.
●For efficiency, use the Remote Air Conditioning System
before departing while the charging cable is connected.

■Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently. If there
is improper tire inflation pressure in the tires, the driving range
when in EV mode 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 consump-
tion.
■Luggage
Carrying heavy luggage can require excessive energy. Avoid
leaving unnecessary luggage in the vehicle.
Also, equipping a large roof rack can cause excessive energy
consumption in the same way as carrying heavy luggage.
■Warming up before driving
Since the gasoline engine starts up and cuts out automatically,
warming up is not necessary.

■Meaning of each icons
Percentage driven in EV mode
using the electric motor (trac-
tion motor) only
The percentage is shown as a
green bar.
Percentage driven in EV mode
jointly using the gasoline
engine and in HV mode
The percentage is shown as a red
bar.
Fuel consumption amount
Gives an indication of the amount
of fuel that has been consumed
by driving in .
Electricity consumption amount
Gives an indication of the amount
of electricity that has been con-
sumed by driving in .

When driving
■Resetting the data
Press and hold the “TRIP” button
while the screen you want to
reset is being displayed.
The bar display, percent display,
driving distance, electricity con-
sumption and fuel consumption
will be reset.
Odometer/trip meter/distance to empty
■Switching the display
The display changes as follows
each time the “TRIP” button is
pressed. Also, if the button is
kept pressed down while the trip
meter is being displayed, the trip
meter will be reset to 0.

■Display items
●Odometer
●Trip meter
●Distance to empty
Displays the total distance the vehicle has been
driven.
Displays the distance the vehicle has been driven
since the meter was last reset. Trip meters A and
B can be used to record and display different dis-
tances independently.
Displays the estimated maximum distance that
can be driven with the quantity of fuel remaining.
•This distance is computed based on your average
fuel consumption. As a result, the actual distance
that can be driven may differ from that displayed.
•When only a small amount of fuel is added to the
tank, the display may not be updated.
When refueling, turn the “POWER” switch off. If the
vehicle is refueled without turning the “POWER”
switch off, the display may not be updated.
