912-1. Plug-in hybrid system
2
Plug-in hybrid system
automatically records the elec-
tricity consumption when being
charged and uses the electricity
consumption for estimating the
EV driving range. Therefore, the
EV driving range displayed
when the hybrid battery (traction
battery) is fully charged may dif-
fer from the previous EV driving
range depending on how the
vehicle was driven.
The EV driving range may
change significantly with each
charging until the electricity con-
sumption based on the recorded
value is stable (for approxi-
mately the first month or two).
However, this does not indicate
a malfunction.
When the air conditioning sys-
tem is turned on, the EV driving
range (with using the air condi-
tioning system) is estimated
based on the past air condition-
ing electricity consumption
amount considering that the
electricity consumption may
become higher.
The distance that EV driving is
possible varies significantly
depending on how the vehicle is
driven, road conditions, the
weather, the outside tempera-
ture, usage conditions of electri-
cal components and the number of occupants.
The distance that EV driving is
possible can be extended if the
following is performed:
■When starting off, depress
the accelerator pedal
smoothly to accelerate
As a guide, accelerate up to
approximately 12mph (20 km/h)
in the first 5 seconds.
Electrical and fuel efficiency can
be improved just by using the
ECO Accelerator Guidance dis-
played on the multi-information
display and taking care to start
off gently. ( P.163)
When the driving mode is set to
Eco drive mode, depressing the
accelerator pedal generates
smooth torque that makes it easier
to operate the accelerator gently.
At the same time, the air condition-
ing control is switched to eco air
conditioning mode ( P.437) to
reduce the strength of the air condi-
tioning operation.
■Maintain sufficient vehicle-
to-vehicle distance and do
not accelerate or decelerate
unnecessarily
Try to maintain a fixed speed
while driving. Driving at a short
vehicle-to-vehicle distance will
result in repeating wasteful
acceleration and deceleration,
which will worsen the electrical
and fuel efficiency.
Tips for extending the EV
driving range

■Hybrid battery (traction bat-
tery) warming control
(Alaska and Canada only)
This control operates after the
AC charging cable remains con-
nected to the vehicle for 3 days
and “Battery Heater” automati-
cally stops. It automatically insu-
lates the hybrid battery (traction
battery) in extremely low tem-
peratures.
 This control stops 31 days
after the AC charging cable is
connected, even if it is still
connected to the vehicle.
 When this control operates,
charging schedule settings
are ignored and charging
starts.
■“Battery Cooler”
When the hybrid battery (trac-
tion battery) is hot and the AC
charging cable is connected to
the vehicle, this function cools
the hybrid battery (traction bat-
tery) before charging is carried
out.
 “Battery Cooler” will operate
when the “Battery Cooler” of
the “Charging Settings” on the
multi-information display is
on. ( P.169)
 When the charging voltage is
120 V, the function does not
operate.
■Traction battery heating and
cooling system (“Battery
Heater” and “Battery Cooler”)
●The system operates when the
hybrid battery (traction battery) is
below or above a certain tempera-
ture.
●The system may operate when
charging is not being performed.
●When the charging schedule is
used ( P.123), this function will
operate according to the charging
schedule.
■“Battery Heater”
●When “Battery Heater” is operat-
ing, the charging indicator illumi-
nates.
●When the AC charging cable is
removed from the vehicle or
remains connected to the vehicle
for approximately 3 days, the sys-
tem automatically stops.
●When “Battery Heater” is operat-
ing during charging, the charging
time may be longer than normal.
●When the shift position is changed
to any position other than P while
“Battery Heater” is operating, the
hybrid battery (traction battery)
heating operation stops.
●“Battery Heater” may operate
even when the hybrid battery
(traction battery) is fully charged
depending on the temperature of
the hybrid battery (traction bat-
tery).
• The remaining charge of the hybrid battery (traction battery)
decreases when “Battery Heater”
operates. The charging operation
may start again to charge the
hybrid battery (traction battery).
• “Charging Stopped Due to Pulled Charging Connector” may be
shown when the charging connec-
tor is removed while recharging.
( P.143)

1142-2. Charging
Also, if the hybrid battery (traction
battery) capacity reduces, the dis-
tance that can be driven in EV mode
or AUTO EV/HV mode decreases.
However, vehicle performance does
not significantly become worse.
■When the remaining charge of
the hybrid battery (traction bat-
tery) is low after charging
In the following situations, the
remaining charge of the hybrid bat-
tery (traction battery) after charging
completes may be less than normal
in order to protect the system (the
EV driving range after the hybrid
battery [traction battery] is fully
charged may be shorter).
*
●Charging is carried out when the
outside temperature is low or high.
●Charging is carried out immedi-
ately after high-load driving or in
extreme heat.
When none of the above situations
apply and there is a drastic drop in
the remaining charge of the hybrid
battery (traction battery) after
charging completes, have the vehi-
cle inspected by your Toyota dealer.
*: When this occurs, even if the remaining charge display of the
hybrid battery (traction battery)
shows that it is fully charged, the
remaining charge rapidly
decreases faster than normal.
■When the charging amount sent
to the hybrid battery (traction
battery) decreases
When the amount of power supplied
by the charger is low or operation of
the “Battery Heater”, etc., reduces
the charging power sent to the
hybrid battery (traction battery), the
charging amount sent to the hybrid
battery (traction battery) may
decrease.
