■Running out of fuel
When the vehicle has run out of fuel
and the hybrid system cannot be
started, refuel th e vehicle with at
least enough gasoline to make the
low fuel level warning light ( P.547)
go off. If there is only a small
amount of fuel, th e hybrid system
may not be able to start. (The stan-
dard amount of fuel is about 2.3 gal.
[8.8 L, 1.9 Imp.gal.], when the vehi-
cle is on a level su rface. This value
may vary when the vehicle is on a
slope. Add extra fuel when the vehi-
cle is inclined.)
■Electromagnetic waves
●High voltage parts and cables on
the Plug-in Hybrid Electric Vehi-
cles incorporate electromagnetic
shielding, and therefore emit
approximately the same amount
of electromagnetic waves as con-
ventional gasoli ne powered vehi-
cles or home electronic
appliances.
●Your vehicle may cause sound
interference in so me third party-
produced radio parts.
■Effect of magnetic forces
If objects that generate strong mag-
netic forces, such as large speak-
ers, are placed inside the luggage
compartment or installed nearby,
the generated magnetic forces may
negatively affect t he hybrid system.
■Hybrid battery (traction battery)
(lithium-ion battery)
The hybrid battery (traction battery)
has a limited service life.
The hybrid battery (traction battery)
capacity (the ability to hold a
charge) reduces with time and use
in the same way as other recharge- able batteries. The extent at which
capacity reduces changes drasti-
cally depending on the environment
(ambient temperature, etc.) and
usage conditions, such as how the
vehicle is driven and how the hybrid
battery (traction battery) is charged.
This is a natural characteristic of
lithium-ion batteries, and is not a
malfunction. Also, even though the
EV driving range becomes shorter
when the hybrid battery (traction
battery) capacity reduces, vehicle
performance does not significantly
become worse.
In order to reduce the possibility of
the capacity reducing, follow the
directions listed on P.119, “Capacity
reduction of the hybrid battery (trac-
tion battery)”.
■Starting the hybrid system in an
extremely cold environment
When the hybrid battery (traction
battery) is extremely cold (below
approximately -22°F [-30°C]) under
the influence of the outside tem-
perature, it may not be possible to
start the hybrid system. In this case,
try to start the hybrid system again
after the temperature of the hybrid
battery increases due to the outside
temperature increase etc.

WARNING
■High voltage precautions
The vehicle has high voltage DC
and AC systems as well as a 12-
volt system. DC and AC high volt-
age is very dangerous and can
cause severe burns and electric
shock that may result in death or
serious injury.

1132-2. Charging
2
Plug-in hybrid system■Charging from an external
power source (P.121)
This is a charging method used
when charging from an AC out-
let (120 V) with the AC charging
cable equipped to the vehicle or
charging at a public charging
station.
The charging start time (or depar-
ture time) and day can be set to
carry out charging using the
charging schedule at the desired
date and time. ( P.128)
■Using the hybrid battery
(traction battery) charge
mode ( P.77)
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.
This vehicle is equipped with
several functions that are linked
with charging.
■“My Room Mode” ( P.148)
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.193)
■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-

Plug-in hybrid system
Before charging, make sure that
each part of the AC charging
cable is in good condition.
(P.104)
■During charging
●The charging starting time may
differ depending on the state of
the vehicle, but this does not indi-
cate a malfunction.
●Cooling fan sounds may be heard
from near the rear seat. ( P.89)
●During charging, sounds may be
heard from near the hybrid battery
(traction battery) in accordance
with the operation of the air condi-
tioning system or “Battery Cooler”
( P.114).
●During and after charging, the rear
seat and its surrounding area in
which the onboard traction battery
charger is installed may get warm.
●The surface of the CCID
(Charging Circuit Interrupting
Device) may become hot, but this
does not indicate a malfunction.
●Depending on radio wave condi-
tions, interference may be heard
on the radio.
●The current charging condition
and the estimated time until
charging will complete can be
checked on the multi-information
display.
■Capacity reduction of the
hybrid battery (traction battery)
The capacity of the hybrid battery
(traction battery) will decline gradu-
ally when the hybrid battery (traction
battery) is in use. The rate at which
it declines will diffe r in accordance
with environmental conditions and
the way in which the vehicle is used.
Observing the following can help suppress battery capacity decline.
●Avoid parking the vehicle in areas
with a high temperature under
direct sunlight when the hybrid
battery (traction battery) is fully
charged.
●Avoid accelerating and decelerat-
ing frequently an
d suddenly when
EV driving.
●Avoid frequent driving near the top
speed for EV driving. ( P.80)
●Leave a low level of charge in the
hybrid battery (traction battery)
when leaving the vehicle undriven
for a long period of time.
After confirming that EV mode or
AUTO EV/HV mode has switched
t o H V m o d e , t u r n t h e p o w e r s w i t c h
off.
●Use the charging schedule func-
tion as much as possible in order
to fully charge the hybrid battery
(traction battery) immediately
before starting off. ( P.128)
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 a fter charging
In the following si tuations, the
remaining charge of the hybrid bat-
tery (traction batte ry) after charging
completes may be less than normal
in order to p rotect the system (the
EV driving range after the 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 char ge of the hybrid
battery (traction battery) after
Inspecting the AC

5728-2. Steps to take in an emergency
was in before the 12-volt battery
was discharged. Before discon-
necting the 12-volt battery, turn
the power switch off.
If you are unsure what mode the
power switch was in before the
12-volt battery discharged, be
especially careful when recon-
necting the 12-volt battery.
■When replacing the 12-volt bat-
tery
●Use a 12-volt battery that con-
forms to European regulations.
●Use a 12-volt battery that the case
size is same as the previous one
(LN2), 20 hours rate capacity
(20HR) is equivalent (55Ah) or
greater, and performance rating
(CCA) is equivalent (345A) or
greater.
• If the sizes differ, the 12-volt bat- tery cannot be properly secured.
• If the 20 hour rate capacity is low,
even if the time period where the
vehicle is not used is a short time,
the 12-volt battery may discharge
and hybrid system may not be
able to start.
●Use a ventilation t ype calcium bat-
tery
●Use a 12-volt battery with a han-
dle. If a 12-volt b attery without a
handle is used, removal is more
difficult.
●When removing the 12-volt bat-
tery: P.496
●After replacing, firmly attach the
following items to the exhaust hole
of the 12-volt battery.
• Use the exhaust hose that was
attached to the 12-volt battery
before replacing an d confirm that
it is firmly connected to the hole
section of t he vehicle.
• Use the exhaust hole plug included with the new 12-volt bat-
tery or the one installed on the
battery prior to t he replacement.
(Depending on the new 12-volt
battery installed, the exhaust hole
may be plugged.) For details, consu
lt your Toyota
