The USB charging ports are
used to supply 2.5A (USB Type-
A) or 3.0A (USB Type-C) of
electricity at 5 V to external
devices. Use the appropriate
terminal for each charging port
type.
The USB charging ports are for
charging only. They are not
designed for data transfer or
other purposes.
Depending on the external
device, it may not charge prop-
erly. Refer to the manual
included with the device before
using a USB charging port.
■Using the USB charging
ports
In the console box
Open the console box lid.
NOTICE
Observe the following precau-
tions.
Failure to do so m ay lead to the
power outlets not operating cor-
rectly or damage to the vehicle or
a connected device.
■To avoid short circuit or mal-
function
●Do not set a device which gen-
erates heat near the interior
components or on a seat. Heat
may cause these parts to melt
or burn.
●Do not use devices which are
sensitive to vibration or heat in
the vehicle.
These devices may malfunction
due to vibration while driving or
heat while the vehicle is parked
in the sun.
●When not using a power outlet,
make sure to close the cover. If
foreign matter or a liquid enters
the power outlet, it may cause a
malfunction or short circuit.
●Do not use a multi-point outlet
adapter as doing so may over-
load the power outlet.
■When the ambie nt tempera-
ture is high
If the temperature inside the vehi-
cle is high, such as after the vehi-
cle has been parked in the sun,
the power outlets may not be able
to be used. Sufficiently ventilate
the interior or use the air condi-
tioning system to c ool the interior
before attempting to use the
power outlets.
■When the ambient tempera-
ture is low
If the vehicle has been stopped in
a cold area, to pro tect the hybrid
battery (traction battery), the
power outlets may not be able to
be used. In this case, drive the
vehicle for a while to warm up the
hybrid battery (traction battery).
■To prevent 12-volt battery dis-
charge
Do not use the pow er outlets lon-
ger than necessary when the
hybrid system is not running.

The 12-volt battery is located in
the right-hand side of luggage
compartment.
■Before recharging
When recharging, the 12-volt bat-
tery produces hydrogen gas which
is flammable and explosive. There-
fore, observe the following precau-
tions before recharging:
●If recharging with the 12-volt bat-
tery installed on the vehicle, be
sure to disconnect the ground
cable.
●Make sure the power switch on
the charger is off when connecting
and disconnecting the charger
cables to the 12-volt battery.
■After recharging/reconnecting
the 12-volt battery
The hybrid system may not start.
Follow the procedure below to ini-
tialize the system.
1 Shift the shift lever to P.
2 Open and close any of the doors.
3 Restart the hybrid system.
●Unlocking the doors using the
smart key system may not be pos-
sible immediately after reconnect-
ing the 12-volt battery. If this
happens, use the wireless remote
control or the mechanical key to lock/unlock the doors.
●Start the hybrid system with the
power switch in ACC. The hybrid
system may not start with the
power switch turned off. How-
ever, the hybrid system will oper-
ate normally from the second
attempt.
●The power switch mode is
recorded by the vehicle. If the 12-
volt battery is reconnected, the
vehicle will return the power
switch mode to the status it was in
before the 1
2-volt battery was dis-
connected. Make sure to turn off
the power switch before discon-
nect the 12-volt battery. Take
extra care when connecting the
12-volt battery if the power switch
mode prior to discharge is
unknown.

7Install the air intake vent
cover.
Insert the tab of the cover as shown
in the illustrati on and push the
cover to engage the claws.
8 Using a Phillips screwdriver,
install the clip.
■Scheduled maintenance of the
air intake vents is necessary
when
In some situations such as when the
vehicle is used frequently or in
heavy traffic or dusty areas, the air
intake vents may need to be
cleaned more regularly. For details,
refer to “Scheduled Maintenance
Guide” or “Owner’s Manual Supple-
ment”.
■Cleaning the air intake vents
●Dust in the air in take vents may
interfere with the cooling of the
hybrid battery (traction battery). If
charging/discharging of the hybrid
battery (traction battery) becomes
limited, the distance that the vehi-
cle can be driven using the electric motor (traction motor) may be
reduced and the fuel economy
may be reduced. Inspect and
clean the air intake vents periodi-
cally.
●Improper handling of the air intake
vent covers and filters may result
in damage to them. If you have
any concerns about cleaning the
filters, contact your Toyota dealer.
■If “Maintenance Required for
Traction Battery Cooling Parts
See Owner’s Manual” is shown
on the multi-information display
●If this warning message is shown
on the multi-information display,
remove the air intake vent covers
and clean the filters. (
P.444)
●After cleaning the air intake vents,
start the hybrid system and check
that the warning message is no
longer shown.
It may take approximately 20 min-
utes after the hybrid system is
started until the warning message
disappears. If the warning mes-
sage does not disappear, have
the vehicle inspected by your
Toyota dealer.
WARNING
■When cleaning the air intake
vents
●Do not use water or other liq-
uids to clean the air intake
vents. If water is applied to the
hybrid battery (traction battery)
or other components, a mal-
function or fire may occur.
●Before cleaning the air intake
vents, make sure to turn the
power switch off to stop the
hybrid system.
■When removing the air intake
vent covers
Do not touch the service plug
located underneath the console
box. ( P.84)
