2023 TOYOTA PRIUS PRIME engine

882-1. Plug-in hybrid system
Primarily using EV mode and
AUTO EV/HV mode when driv-
ing in cities and using HV mode
when driving on highways (or
freeways) can help conserve
fuel and electricity. (P.74)
When using Eco drive mode, the
torque corresponding to the
accelerator pedal depression
amount can be generated more
smoothly than it is in normal
conditions. In addition, the oper-
ation of the air conditioning sys-
tem (heating/cooling) will be
minimized, improving fuel and
electricity economy. ( P.422)
Eco-friendly driving is possible
by keeping the Hybrid System
Indicator within Eco area.
( P.158) Shift the shift position to D when
stopped at a traffic light, or driv-
ing in heavy traffic etc. Shift the
shift position to P when parking.
When using the N, there is no
positive effect on fuel consump-
tion. In the N, the gasoline
engine operates but electricity
cannot be generated. Also,
when using the air conditioning
system, etc., the hybrid battery
(traction battery) power is con-
sumed.

Drive your vehicle smoothly.
Avoid abrupt acceleration and
deceleration. Gradual accel-
eration 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 con-
sumes hybrid battery (trac-
tion battery) po wer, resulting
in poor fuel consumption. Bat-
tery power can be restored by
driving with the accelerator
pedal slightly released.
Make sure to operate the brakes

Carrying heavy luggage will lead
to poor fuel economy. Avoid car-
rying unnecessary luggage.
Installing a large roof rack will
also cause poor fuel economy.
Since the gasoline engine starts
up and cuts out automatically,
warming up is not necessary.The value displayed on the SOC
(State of Charge) gauge
(P.155) is estimated from the
following information.
 The amount of hybrid battery
(traction battery) charge cur-
rently remaining
 The electricity consumption
(the estimated distance that
EV driving is possible per unit
of electrical energy) based on
the recorded value
 Past air conditioning system
electricity consumption
amount
The electricity consumption var-
ies depending on how the vehi-
cle is driven. The vehicle

EV driving range
The EV driving range dis-
played on the meter shows
the reference distance that
EV driving (driving using
only the electric motor) is
possible, and the actual dis-
tance that can be driven
may differ from that dis-
played.
Even if the EV driving range is
displayed, EV driving may be
canceled and both gasoline
engine and electric motor are
used depending on the situa-
tion. ( P.79)

1082-2. Charging
■AC charging (P.116)
This is a charging method used
when charging from an AC out-
let with the AC charging cable or
charging that use an AC char-
ger.
By setting charging schedule, it is
also possible to charge at the
desired date and time. ( P.123)
■Using the hybrid battery
(traction battery) charge
mode ( P.75)
The plug-in hybrid system can
be switched to hybrid battery
(traction battery) charge mode
to charge the hybrid battery
(traction battery) using electricity
generated by gasoline engine
operation.
The maximum charge amount in
the hybrid battery (traction battery)
charge mode is approximately 80%
of the fully charged capacity for the
charging from an external power
source.
■Solar charging system (if
equipped) ( P.136)
In certain conditions, when the vehicle is parked, the hybrid bat-
tery (traction battery) can be
charged by using electricity gen-
erated by the solar panel
equipped to the roof of the vehi-
cle.
This vehicle is equipped with
several functions that are linked
with charging.
■“My Room Mode” (
P.134)
When the AC charging cable is
connected to the vehicle, electri-
cal components such as the air
conditioning system or audio
system can be used using the
external power source
*.
*: The power of the hybrid battery (traction battery) may be used
depending on the situation.
■“Battery Heater”
When the outside temperature
is low and the AC charging
cable is connected to the vehi-
cle, this function automatically
warms the hybrid battery (trac-
tion battery) until it reaches or
exceeds a certain temperature.
“Battery Heater” will operate
when the “Battery Heater” of the
“Charging Settings” on the multi-
information display is on.
( P.169)
 By setting charging schedule,
“Battery Heater” operates
according to the charging
Charging methods
The following methods can
be used to charge the
hybrid battery (traction bat-
tery).

*: When used in this manual, “regen- eration” refers to the conversion of
energy created by the movement
of the vehicle into electrical
energy. In the following situation, the Hybrid
System Indicator does not operate.
●“READY” indicator is not illumi-
nated.
●The shift position is in a position
other than D or B.
■SOC (State of Charge) gauge
Displays the current amount of
charge remaining in the traction bat-
tery.
●The remaining battery for EV driv-
ing in EV mode is displayed in
green, and the remaining battery
used in HV mode is displayed in
blue.
●The amount of the remaining bat-
tery displayed decrease as the
vehicle is driven and increase
when the hybrid battery (traction
battery) is charged, electrical
energy is regenerated using the
regenerative braking ( P.78) or
electricity is generated by the gas-
oline engine.
●If the remaining battery is not dis-
played in green, HV mode is auto-
matically selected and EV mode
cannot be used. To enable EV
driving, charge the hybrid battery
(traction battery). ( P.94)
