When a certain level of impact is
detected by the impact sensors,
the emergency shut off system turns off the EV system and
blocks the high voltage current.
If the emergency shut off system
activates, your vehicle will not
restart. To restart the EV sys-
tem, contact your Toyota dealer.
A message is automatically dis-
played when a malfunction
occurs in the EV system or an
improper operation is attempted.
If a warning message is shown
on the multi-information display,
read the message and follow the
instructions. (
P.140, 522)
■If a warning light comes on, a
warning message is displayed,
or the 12-volt battery is discon-
nected
The EV system may not start.
In that case, try to start the system
again. If the “READY” indicator does
not come on, contact your Toyota
dealer.
■When the traction battery is
completely discharged
When the EV system cannot be
started due to the traction battery
being completely discharged, restart
the system after AC charging or DC
charging. When charging, it is rec-
WARNING
■Caution while driving
●Pay special attention to the area
around the vehicle. Because
there is no engine noise, pedes-
trians, people riding bicycles or
other people and vehicles in the
area may not be aware of the
vehicle starting off or approach-
ing them, so take extra care
while driving. Therefore, take
extra care while driving even if
the Acoustic Vehicle Alerting
System is active.
●If the vehicle under floor area
receives strong shock or impact
while driving, stop the vehicle in
a safe place and check around
the bottom of the vehicle. If
there is damage to the traction
battery or liquid leakage, it may
lead to a vehicle fire, etc. Do not
touch the vehicle and immedi-
ately contact your Toyota dealer.
Even if no damage can be seen
under the floor, the traction bat-
tery may be damaged. If the
vehicle received an impact
under the floor, have the traction
battery inspected at a Toyota
dealer.
■Modifications
Do not make modifications that
lower the height of the vehicle.
The traction battery in the under
floor area may come into contact
with the ground when the height
of vehicle is lowered. If the trac-
tion battery is damaged, a vehicle
fire may occur, possibly resulting
in death or serious injury.

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.

■Automatic check function
This is an automatic system
check that is run before
charging begins to check for
problems in the operation of the
electrical leakage detection
function.
If a malfunction is found in the elec-
trical leakage detection function as
a result of the c heck, the error
warning indicator flashes to inform
the user. ( P. 9 0 )
■Temperature detection
function
A temperature detection func-
tion is equipped to the plug.
While charging, if heat is gener-
ated due to looseness on the
outlet side etc., this function
suppresses heat by controlling
the charging current.
■Conditions for supplying
current to the vehicle
The CCID (Charging Circuit
Interrupting Device) is designed
to prevent electrical current from
being supplied to the charging
connector when it is not con-
nected to the vehicle, even if the plug is inserted into the outlet.
■Indicator operation
3 indicators are used to indicate
the following conditions.
Power indicator
Illuminates when electricity is flow-
ing to the CCID (C harging Circuit
Interrupting Device).
Charging indicator
Illuminates when charging is in
progress.
Error warning indicator
Flashes when there is an electrical
leakage or when a malfunction
occurs in the CCI D (Charging Cir-
cuit Interrupting Device).
■When a malfunction occurs during charging
The indicators on the CCID (Charging Circuit Interrupting Devic e)
use a combination of different statuses (not illuminated, illum inated
or flashing) to inform the user of internal malfunctions.
When the error wa rning indicator is illuminated or flashing, te mporarily
remove the plug from the outlet and then reconnect it to check if the error
indicator turns off.
If the error warning indicator turns off, charging is now possi ble.
