1222-2. Charging
2Pull the charging connector
towards you while pressing
the latch release button.
If the latch release button is
pressed during charging (while the
charging indicator is illuminated),
charging will be interrupted.
3Attach the charging connec-
tor cap.
4 Close the charging port lid.
5 Remove the plug from the
outlet when the charging
equipment will not be used for a prolonged period of
time.
Hold the body of the plug when
removing.
Make sure to put the cable away
immediately after disconnecting.
(
 P.123)
When leaving the plug inserted,
inspect the plug and connector
once a month to check if dirt or dust
has accumulated.
■When the outside temperature
is low or high
The level shown on the SOC (State
of Charge) gauge ( P.155) may
drop slightly when the power switch
is turned to ON, even if charging
has been completed and the hybrid
battery (traction battery) is fully
charged. However, this does not
indicate a malfunction.
■When removing the charging
connector
Press the latch release button,
check that the lever raises up, and
then pull the charging connector
towards you.
If the lever does not raise up even
after the latch release button is
pressed, the charging connector is
locked. If this occurs, unlock the
doors using the smart key system or
wireless remote control to unlock
the charging connector. ( P.102)

1804-1. Key information
4-1.Key information
The following keys are provided
with the vehicle.Electronic keys
• Operating the smart key system ( P.203)
• Operating the wireless remote control function ( P.182)
Mechanical keys
Key number plate
■When riding in an aircraft
When bringing an electronic key
onto an aircraft, make sure you do
not press any buttons on the elec-
tronic key while inside the aircraft
cabin. If you are carrying an elec-
tronic key in your bag etc., ensure
that the buttons are not likely to be
pressed accidentally. Pressing a
button may cause the electronic key
to emit radio waves that could inter-
fere with the oper ation of the air-
craft.
■Electronic key battery depletion
●The standard battery life is 1 to 2
years.
●If the battery becomes low, an
alarm will sound in the cabin and a
message will be displayed on the
multi-information display when the hybrid system stops.
●To reduce key ba
ttery depletion
when the electronic key is to not
be used for long periods of time,
set the electronic key to the bat-
tery-saving mode. ( P.205)
●As the electronic key always
receives radio waves, the battery
will become depleted even if the
electronic key is not used. The fol-
lowing symptoms indicate that the
electronic key battery may be
depleted. Replace the battery
when necessary.
• The smart key system or the wire- less remote control does not oper-
ate.
• The detection area becomes smaller.
• The LED indicator on the key sur- face does not turn on.
You can replace the battery by your-
self ( P.538). However, as there is
a danger that the electronic key may
be damaged, it is recommended
that replacement is carried out by
your Toyota dealer.
●To avoid serious deterioration, do
not leave the electronic key within
3 ft. (1 m) of the following electri-
cal appliances that produce a
magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Table lamps
• Induction cookers
●If the electronic key is near the
vehicle for longer than necessary,
even if the smart key system is not
operated, the key battery may
become depleted faster than nor-
mal. When not operating the
smart key system, it is recom-
mended to not stay with the elec-
tronic key near the vehicle longer
than necessary.

key inside the vehicle, leaving the
vehicle carrying the electronic key
on your person without turning the
power switch to OFF or other pas-
sengers from unintentionally taking
the key out of the vehicle, etc., a
message that prompts the user to

key number
The number of keys already regis-
tered to the vehicle can be con-
firmed. Ask your Toyota dealer for
details.
■If “A New Key has been Regis-
tered Contact Your Dealer for
Details” is displayed on the
multi-information display
This message will be displayed
each time the driver’s door is
opened when the doors are
unlocked from the outside for
approximately 10 days after a new
electronic key has been registered.
If this message is displayed but you
have not had a new electronic key
registered, ask your Toyota dealer
to check if an unknown electronic
key (other than those in your pos-
session) has been registered.
NOTICE
■To prevent key damage
●Do not drop the keys, subject
them to strong shocks or bend
them.
●Do not expose the keys to high
temperatures for long periods of
time.
●Do not get the keys wet or wash
them in an ultrasonic washer,
etc.

netic materials to the keys or
place the keys close to such
materials.
●Do not disassemble the keys.
●Do not attach a sticker or any-
thing else to the surface of the
electronic key.
●Do not place the keys near
objects that produce magnetic
fields, such as TVs, audio sys-
tems and induction cookers.
●Do not place the keys near
medical electrical equipment
such as low-fr equency therapy
equipment or microwave ther-
apy equipment, and do not
receive medical attention with
the keys on your person.
■Carrying the electronic key
on your person
Carry the electronic key 3.9 in.
(10 cm) or more away from elec-
tric appliances that are turned on.
