PRIUS PHV_OM_OM47818U_(U)
■Cruising range
Displays the estimated distance that can be driven with the quantities of fuel
and hybrid battery (traction battery) charge currently 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 dis-
played.
■ Odometer/trip meter/distance to empty
The odometer/trip meter/distance to empty will not be displayed while the
monthly fuel consumption record is being displayed.

Plug-in hybrid vehicle driving tips
For economical and ecological driving, pay attention to the following
points:
■ 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 con-
serve fuel and electricity. ( P. 3 7 )
■ Using Eco drive mode
When using Eco drive mode, a torque corresponding to the
accelerator pedal depression amount can be generated more
smoothly than it is in normal conditions. In addition, the opera-
tion of the air conditioning system (heating/cooling) will be mini-
mized, improving fuel a nd electricity economy. ( P. 247)
■ Use of Hybrid System Indicator
Eco-friendly driving is possible by keeping the Hybrid System
Indicator within Eco area. ( P. 268)
■ When braking the vehicle
Make sure to operate the brakes gently and in good time. A
greater amount of electrical energy can be retained 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 l eaving and avoid delays as much
as possible. When encountering a delay, 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 excessive electric ity and fuel consumption.

■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 reta ined when slowing down.
Electricity consumptio n will increase substantially when driving
at high speeds in EV mode. If ther e will be a long distance to the
next external charging point afte r 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 cont rol 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 gasoli ne 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 Remo te Air Conditioning System
before departing while the c harging 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 lar ge amounts of friction, their use
on dry roads can lead to increas ed fuel and electricity consump-
tion.
■ Luggage
Carrying heavy luggage can require excessive energy. Avoid
leaving unnecessary lu ggage 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.
