*: For details regarding setting clock, refer to “MULTIMEDIA OWNER’S
MANUAL”.
■Cannot change charging schedule from smartphone applica-
tion (if equipped)
*
*: In order to use the smartphone application, it is necessary to apply to Toyota Apps. For details about Toyota Apps, refer to
http://www.toyota.com/connectedservices
in the United States and

in Canada.
■Charging starts, even though charging schedule is registered
AC charging connector is not con-
nected to vehicleBefore using the charging schedule,
connect the AC charging connector.
AC charging connector was con-
nected after set time
Connect the AC charging connector
before the time set in “Start” or “Start
at set time”.
When the charging mode is set to
“Start-Stop” or “Start and stop at set
times”, the hybrid battery (traction
battery) will charge even if the start
time has passed, if the AC charging
connector is connected before the
stop time.

smartphone is outside its coverage
area, move to a place with a better
signal.

■Hybrid System IndicatorCharge area
Shows regeneration
* status. Regen-
erated energy will be used to charge
the hybrid battery (traction battery).
Eco area
Shows that the vehicle is being
driven in an Eco-friendly manner.
By keeping the indicator needle
within Eco area, more Eco-friendly
driving can be achieved.
Power area
Shows that an Eco-friendly driving
range is being exceeded (during full
power driving etc.)
Hybrid Eco area (HV mode)
Shows that gasoline engine power
is not being used very often.
The gasoline engine will automati-
cally stop and restart under various
conditions.
EV driving area (EV mode or
AUTO EV/HV mode)
Shows that the vehicle is driven
using only the electric motor (trac-
tion motor).
*: When used in this manual, “regen- eration” refers to the conversion of
energy created by the movement
of the vehicle into electrical
energy. In the following situation, the Hybrid
System Indicator does not operate.
●“READY” indicator is not illumi-
nated.
●The shift position is in a position
other than D or B.
■SOC (State of Charge) gauge
Displays the current amount of
charge remaining in the traction bat-
tery.
●The remaining battery for EV driv-
ing in EV mode is displayed in
green, and the remaining battery
used in HV mode is displayed in
blue.
●The amount of the remaining bat-
tery displayed decrease as the
vehicle is driven and increase
when the hybrid battery (traction
battery) is charged, electrical
energy is regenerated using the
regenerative braking ( P.78) or
electricity is generated by the gas-
oline engine.
●If the remaining battery is not dis-
played in green, HV mode is auto-
matically selected and EV mode
cannot be used. To enable EV
driving, charge the hybrid battery
(traction battery). ( P.94)

■Distance to empty
●This distance is computed based
on your average fuel consump-
tion. As a result, the actual dis-
tance that can be driven may
differ from that displayed.
●When only a small amount of fuel
is added to the tank, the display
may not be updated. When refuel-
ing, turn the power switch off. If
the vehicle is refueled without
turning the power switch off, the
display may not be updated.
●When “Refuel” is displayed, the
remaining fuel amount is low and
the distance that can be driven
with the remaining fuel cannot be
calculated. Refuel immediately.
■EV driving range
●When the air conditioning system
is operating, is displayed next
to the EV driving range and the
EV driving range with the air con-
ditioning system on is displayed.
●The EV driving range may shorten
even when not driving due to
power consumption by the sys-
tem.
●For details, refer to “EV driving
range” (P.90)
■Outside temperature display
●Displays the outside temperature
within the range of -40°F (-40°C)
to 140°F (60°C).
●When the outside temperature is
approximately 37°F (3°C) or
lower, the indicator will flash
for approximately 10 seconds,
then stay on.
●In the following situations, the cor-
rect outside temperature may not
be displayed, or the display may
take longer th an normal to
change.
• When stopped, or driving at low speeds (less than 12 mph [20
km/h])
• When the outside temperature has changed suddenly (at the
entrance/exit of a garage, tunnel,
etc.)
●When “--” or “E” is displayed, the
system may be malfunctioning.
Take your vehicle to your Toyota
dealer.
■Liquid crystal display
Small spots or light spots may
appear on the display. This phe-
nomenon is characteristic of liquid
crystal displays, and there is no
problem continuing to use the dis-
play.

■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.
