Multi-information display
Press the “DISP” button to dis-
play the energy monitor.
■Names and meaning of each icons
Gasoline engine
Hybrid battery (traction bat-
tery)
Electric motor (traction motor)
EV driving range
Displays the approximate driving
range using only the electric
motor (traction motor) when in EV
mode or when enough power is
remaining for EV mode. The dis-
play turns off if the charge level of
the hybrid battery (traction bat-
tery) reduces and HV mode is
selected.
(The display will not turn off if HV
mode is selected using the EV/
HV mode selection switch.)

■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.

1-7. Refueling
PRIUS PHV_OM_OM47856U_(U)
NOTICE
■Refueling
●Finish refueling within 30 minutes. If more than 30 minutes passes, the
internal valve closes. In this condition, fuel may spill out if you continue to
refuel the vehicle. About 5 minutes after the valve is closed, a message
“CLOSE FUEL LID” will appear on the multi-information display. To refuel
the vehicle again, tighten fuel tank cap and close the fuel filler door, and
then press the fuel filler door opener switch again.
●Do not spill fuel during refueling.
Doing so may damage the vehicle, such as causing the emission control
system to operate abnormally or damaging fuel system components or the
vehicle’s painted surface.
■Notice about fuel
For plug-in hybrid vehicles, fuel may remain in the tank for a long time and
undergo changes in quality depending on the how the vehicle is used.
Refuel at least 5.3 gal.(20 L, 4.4 Imp.gal.) of fuel every 6 months (refuel a
total of at least 5.3 gal. [20 L, 4.4 Imp.gal.] over a 6-month period), as this
may affect components of the fuel system or the gasoline engine.

When driving
■Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability
of the correct fuel. (→P. 6 1 7 )
■For efficient use
●Shift the shift position to D when driving.
In the N position, the gasoline engine operates but electricity cannot be
generated. The hybrid battery (traction battery) will discharge, requiring
unnecessary engine power to charge.
●Drive your vehicle smoothly.
Avoid abrupt acceleration and deceleration. Gradual acceleration 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 acceleration. Battery power can be restored by driving
with the accelerator pedal slightly released.
●Shift the shift position to P when parking.
In the N position, the hybrid battery (traction battery) does not charge.
Leaving the shift position in the N position for an extended period of time
may discharge the hybrid battery (traction battery). The vehicle cannot
run if the hybrid battery (traction battery) is discharged.
