2023 TOYOTA PRIUS PRIME steering

922-1. Plug-in hybrid system
■Release the accelerator
pedal early before stopping
the vehicle, such as at a
traffic light
The regenerative brake will
operate to convert the kinetic
energy of the vehicle into electri-
cal energy, which will charge the
hybrid battery (traction battery).
The regeneration status can be
checked from the Hybrid Sys-
tem Indicator. ( P.158)
When the brake pedal is
depressed lightly during decel-
eration, the regeneration
amount increases, enabling
more electrical energy to be
recovered.
If the brake pedal is depressed too
strongly, the recovered amount
indicator will reach the maximum
level and the upper limit of the
recoverable en ergy will be
exceeded. Therefore, be sure to
operate the brake pedal early.
■Use the air conditioning
system appropriately, and
also utilize the heated steer-
ing wheel (if equipped) and
seat heaters (if equipped)
In EV mode, the vehicle is
cooled and heated by electrical
energy. (Except in extremely
cold temperatures of approxi-
mately 14°F [-10°C] or less.)
Preventing excessive cooling or
heating of the vehicle will reduce
power consumption and
improve electrical efficiency. When eco air conditioning mode
is used, the air conditioning con-
trol is switched automatically to
a lower setting. (
P.437)
The heated steering wheel and
seat heaters are efficient heat-
ing device that directly warm the
body using less electric power.
When used together with the air
conditioning system, a low tem-
perature setting can be used to
improve electrical and fuel effi-
ciency.
■Check the tire pressure
If the tire pressure is lower than
the specified value, it will
worsen the electrical and fuel
efficiency.
A pressure level 7 psi (50 kPa, 0.5
kgf/cm
2 or bar) lower than the spec-
ified value will cause a worsening of
several percentage points.
■When driving on highways,
use the EV/HV mode selec-
tion switch to drive in HV
mode
The power consumption will
increase significantly if the vehi-
cle is driven in EV mode on
highways.
■Do not load unnecessary
objects in the vehicle
Driving with objects weighing
220 lb. (100 kg) in the vehicle
will worsen the electrical and
fuel efficiency by approximately
3%.
Air resistance also greatly

Plug-in hybrid system
■While using “My Room Mode”
Any of the following may occur.
●When the remaining charge of the
hybrid battery (traction battery)
reaches the lower limit, the air
conditioning system automatically
turns off.
In this situation, the air conditioning
system cannot be used until the
remaining charge of the hybrid bat-
tery (traction battery) increases.
Turn the power switch off and use
“My Room Mode” after the remain-
ing charge of the hybrid battery
(traction battery) is restored.
●When the outside temperature is
low, the heater output may be lim-
ited due to the air conditioning
system operation being restricted.
●Warning lights and indicators such
as electric power steering system
warning light (yellow) and mal-
function indicator lamp may turn
on, but this is not a malfunction.
Also, when the headlight switch is
in the AUTO position (if equipped)
and the surrounding area is dark,
the headlights are turned on.
(  P.269)
■When a charging schedule is
registered
When “My Room Mode” starts while
the charging schedule is on
standby, charging schedules are
ignored and charging starts.
■When “My Room Mode” is used
while the hybrid battery (trac-
tion battery) is fully charged
When the power switch is turned on
while the hybrid battery (traction
battery) is fully charged and the
charging connector that supplies
power is connected, “Charging Port
Lid is Open” is displayed on the
multi-information di splay. In this
case, press on the meter control switches to display the setting
screen of “My Room Mode”, and
then select “My Room Mode”.
When “My Room Mode” is used
while the hybrid
battery (traction
battery) is fully charged, the electric
power of the hybrid battery (traction
battery) may be consumed. In this
case, charging may be performed
again.
■When a message related to “My
Room Mode” is displayed
When a message is displayed on
the multi-information display while
using or attempti ng to start “My
Room Mode”, take the following cor-
rection procedures.
●“Traction battery is too low for “My
Room Mode””
There is insufficient remaining
charge in the hybrid battery (traction
battery) for starting “My Room
Mode”.
Wait until the charge of the hybrid
battery (traction battery) increases,
then start “My Room Mode”.
●““My Room Mode” has stopped
due to low traction battery”
The remaining charge in the hybrid
battery (traction ba ttery) is insuffi-
cient.
Stop using “My Room Mode” and
charge the hybrid battery (traction
battery).
●““My Room Mode ” will stop when
traction battery is too low Reduce
power usage to continue using
“My Room Mode””
The power consumption inside the
vehicle is greater than the power
being charged to the hybrid battery
(traction battery), and the remaining
charge of the hybrid battery (traction
battery) is low.
