WARNING
●Do not kick the front passenger
seat or subject it to severe
impact. Otherwise, the SRS
warning light may come on to
indicate a malfunction of the
front passenger occupant clas-
sification system. In this case,
contact your Toyota dealer
immediately.
●Child restraint systems installed
on the rear seat should not con-
tact the front seatbacks.
●Do not use a seat accessory,
such as a cushion and seat
cover, that covers the seat
cushion surface.
●Do not modify or replace the
upholstery of the front seat.
●Adjust the front passenger seat
so that the head restraint does
not touch the ceiling. If the head
restraint is left in contact with
the ceiling, the system may not
detect the front passenger prop-
erly, leading to improper opera-
tion of the airbags.

■There is a malfunction in the system
*1: The system judges a person of adult size as an adult. When a smaller
adult sits in the front passenger seat, the system may not recognize
him/her as an adult depending on his/her physique and posture.
*2: In the event the front passenger is wearing a seat belt.
*3: In the event the front passenge r does not wear a seat belt.
*4: For some children, child in seat, child in booster seat or chi ld in convert-
ible seat, the system may not recognize him/her as a child. Fac tors
which may affect this can be the physique or posture.
*5: Never install a rear-facing ch ild restraint system on the front passenger
seat. A forward-facing child restraint system should only be in stalled on
the front passenger sea t when it is unavoidable. ( P.52)
*6: In case the indicator light is not illuminated, consult this m anual on how
to install the child restr aint system properly. (P. 5 0 )

Electric Vehicle system
Provides electricity to various vehicle systems such as the SRS airbags,
headlights, wipers, etc.
*: AWD models only
■When braking (regenera-
tive braking)
The electric motor (traction
motor) charges the traction bat-
tery.
The driving range can be
extended by actively using this
regenerative braking to store
electricity in the traction battery.
The battery electric vehicle is
driven using electricity, which is
received from an external power
source and stored in the traction
battery. Not only public charging
stations, but also household out-
lets can be used for charging.
Procedures are different from
refueling a conventional vehi-
cle. Therefore, make sure to
read the following thoroughly.
 Charging equipment ( P.85)
 AC charging cable ( P. 8 7 )
 Power sources that can be
used ( P.102)
 Things to know before
charging ( P.102)
 How to charge your vehicle
( P.105, 113)
 When charging cannot be
performed normally ( P.133)■Regenerative braking
In the following situ ations, kinetic
energy is converted to electric
energy and deceler ation force can
be obtained in con junction with the
recharging of the traction battery.
●The accelerator pedal is released
while driving with the shift position
in D.
●The brake pedal is depressed
while driving with the shift position
in D.
■Charging the 12-volt battery
The 12-volt battery is charged from
the traction battery when the EV
system is operated or while the trac-
tion battery is being charged.
If the vehicle has not been used for
a long time, the 12- volt battery may
become low due to self-discharge. If
this occurs, follow the correct proce-
dures. ( P.541)
■When not using t he vehicle for
an extended period of time
●When the vehicle will not be used
for an extended period of time,
charge the traction battery once a
month.
This protects the traction battery
from extreme voltage decline due
to self discharging.
●When the vehicle will not be used
for an extended period of time, the
12-volt battery will be charged
from the traction battery to reduce
the risk of the 12- volt battery dis-
charged. In this c ase, the cooling
fan may operate, however it is not
a malfunction.
●To p r e v e n t t h e 1 2 - v o l t b a t t e r y f r o m

charging port lid open or the
charging cable connected to the
vehicle.

battery cannot be charged. Also,
when using the air conditioning
system, etc., the traction battery
electricity is consumed.
(P.237)
Repeated acceleration and
deceleration due to traffic con-
gestion, long waits at traffic
lights, and driving on steep
inclines will lead to poor electric-
ity consumption. In order to
avoid those situations as much
as possible, check traffic reports
before leaving. If the vehicle is
driven in traffic congestion, gen-
tly release the brake pedal to
allow the vehicle to move for-
ward slightly, avoid overuse of
the accelerator pedal. Doing so
can help minimize unnecessary
electricity consumption.
Make sure to operate the brakes
gently and a timely manner. A
greater amount of electrical
energy can be regenerated
when slowing down.
Control and maintain the vehicle
at a constant speed. Before
stopping at a toll booth or simi-
lar, allow plenty of time to release the accelerator and gen-
tly apply the brakes. A greater
amount of electrical energy can
be regenerated when slowing
down.

Use the air conditioning only
when necessary. Doing so
can help reduce excessive
electricity consumption.
In summer: When the ambient tem-
perature is high, use the recircu-
lated air mode. Doing so will help to
reduce the burden on the air condi-
tioning system and reduce electric-
ity consumption as well.
In winter: Exce ssive or unneces-
sary heating should be avoided.
Also, electricity consumption can
be improved by avoiding overuse of
the heater.
 When using the Remote Air
Conditioning System
( P.409) while the AC
charging cable is connected
to the vehicle, electricity con-
sumption immediately after
starting off will be reduced
because air conditioning is
operated mainly using elec-
tricity from an external power
source.
Make sure to check the tire infla-
tion pressure frequently.

Before charging, always check
the following items.
 The parking brake is applied.
( P.243)
 The power switch is turned to
OFF. ( P.231)
 Lights such as the headlights,
emergency flashers and inte-
rior lights, etc. are turned off.
If these light switches are turned
on, then these features will con-
sume electricity, and charging time
will increase.
Before charging, make sure that
each part of the AC charging
cable is in good condition.
( P.92)
■During charging
●The charging starting time may
differ depending on the state of
the vehicle, but this does not indi-
cate a malfunction.
●During charging, sounds may be
heard from near the traction bat-
tery in accordance with the opera-
tion of the air conditioning system
or “Battery Cooler” ( P.99).
●During and after charging, the motor compartment and its sur-
rounding 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.
■When charging using a public
charging facility
●When charging using a public
charging facility, check the setting
of the charging schedule function.
• When the charging schedule is registered, temporarily turn off the
function or turn “ Charge Now” on.
(  P. 1 1 9 )
• When the charging schedule is set to on, charging will not start even
if the AC charging cable is con-
nected. Also, charging fee may
occur due to connection of the AC
charging cable.
■Capacity reduction of the trac-
tion battery
The capacity of the traction battery
will decline gradually when the trac-
tion battery is in use. The rate at
which it declines will differ in accor-
dance with environmental conditions
and the way in which the vehicle is
used. Observing the following can
help suppress the decline in the
traction battery capacity.
●Avoid parking the vehicle in high
temperature areas, under direct
sunlight when the traction battery
is fully charged.
●Avoid accelerating and decelerat-
ing frequently and suddenly.
●Avoid frequent d riving at high
speed.
●Use the charging schedule func-
tion as much as possible in order
to fully charged the traction bat-
tery before starting off. ( P. 1 1 8 )
NOTICE
●When charging with a charger,
follow the procedures for using
each charger.
Confirm the following
before charging
Inspecting the AC
charging cable

1042-2. Charging
Owners Manual_USA_M42C01_en
●Avoid frequent DC charging
Also, if the capacit y of the traction
battery capacity reduces, the dis-
tance that can be driven decreases.
However, vehicle performance does
not significantly become worse.
■When the remaining charge of
the traction battery is low after
charging
In the following situations, the
remaining charge of the traction bat-
tery after charging completes may
be less than normal in order to pro-
tect the traction bat tery (the driving
range after the battery is fully
charged may be shorter).
*
●Charging is perf ormed when the
outside temperature is low or high
●Charging is perf ormed immedi-
ately after high-l oad driving or in
extreme heat
In any other situati on, if the remain-
ing charge of the traction battery is
significantly lower than normal after
charging completes, have the vehi-
cle inspected by your Toyota dealer.
*: When this occurs, even if the remaining charge display of the
traction battery shows that it is
fully charged, the remaining
charge rapidly decreases faster
than normal.
■When the charging amount sent
to the 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 traction
battery, the charging amount sent to
the traction battery may decrease.
