●The wireless charger is designed to supply low power electricity (5 W or
less) to a cellular phone, smartphone, or other portable device.
■If a cover or accessory is attached to the portable device
Do not charge a portable device if a cover or accessory which is not Qi com-
patible is attached. Depending on the type of cover and/or accessory
attached, it may not be possible to charge the portable device. If the portable
device is placed on the charging area and does not charge, remove the cover
and/or accessories.
■If interference is heard in AM radio broadcasts while charging
Turn off the wireless charger and check if the noise is reduced. If noise is
reduced, press and hold the power supply switch of the wireless charger for 2
seconds. The frequency of the wireless charger is changed and noise may be
reduced. When the frequency is changed, the operation indicator light will
blink (orange) 2 times.
■Charging precautions
●If the electronic key cannot be detected in the cabin, charging cannot be
performed. When a door is opened and closed, charging may be temporarily
suspended.
●While charging, the wireless charger and the portable device will become
warm. This is not a malfunction.
If a portable device becomes warm while charging and charging stops due
to the protection function of the portable device, wait until the portable
device cools down and charge it again.
■Sound generated during operation
When the power supply switch is turned on or while a portable device is being
identified, operation sounds may be heard. This is not a malfunction.

NOTICE
■Conditions in which the wireless charger may not operate correctly
In the following situations, the wireless charger may not operate correctly:
●When a portable device is fully charged
●When there is a foreign object between the charging area and portable
device
●When a portable device becomes hot while charging
●When a portable device is placed on the wireless area with its charging
surface facing up
●When a portable device is not centered on the charging area
●When the vehicle is near a TV tower, electric power plant, gas station,
radio station, large display, airport or other facility that generates strong
radio waves or electrical noise
●When the portable device is in contact with, or is covered by any of the fol-
lowing metallic objects:
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum foil inside
• Metallic wallets or bags
• Coins
• Metal hand warmers
• Media such as CDs and DVDs
●When wireless keys (that emit radio waves) other than those of your vehi-
cle are being used nearby.
If in situations other than above the wireless charger does not operate prop-
erly or the operation indicator light is blinking, the wireless charger may be
malfunctioning. Contact your Toyota dealer.
■To prevent failure or damage to data
●Do not bring magnetic cards, such as a credit card, or magnetic recording
media, close to the wireless charger while charging. Otherwise, data may
be erased due to the influence of magnetism.
Additionally, do not bring precision instruments such as wrist watches,
close to the wireless charger, as such objects may malfunction.
●Do not leave portable devices in the cabin. The temperature inside the
cabin may become high when parked in the sun, and cause damage to the
device.
■To prevent 12-volt battery discharge
Do not use the wireless charger for a long period of time with the hybrid sys-
tem stopped.

4126-3. Do-it-yourself maintenance
Make sure that the 12-volt battery terminals are not corroded and that
there are no loose connections, cracks, or loose clamps.

■Before recharging
When recharging, the 12-volt battery produces hydrogen gas which is flam-
mable and explosive. Therefore, observe the following precautions before
recharging:
●If recharging with the 12-volt battery installed on the vehicle, be sure to dis-
connect the ground cable.
●Make sure the power switch on the charger is off when connecting and dis-
connecting the charger cables to the 12-volt battery.
■After recharging/reconnecting the 12-volt battery
●Unlocking the doors using the smart key system may not be possible imme-
diately after reconnecting the 12-volt battery. If this happens, use the wire-
less remote control or the mechanical key to lock/unlock the doors.
●Start the hybrid system with the power switch in ACCESSORY mode. The
hybrid system may not start with the power switch turned off. However, the
hybrid system will operate 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 12-volt battery was disconnected. Make sure to turn off
the power before disconnecting the 12-volt battery. Take extra care when
connecting the 12-volt battery if the power switch mode prior to discharge is
unknown.
If the system will not start even after multiple attempts, contact your Toyota
dealer.

Maintenance and care
■Scheduled maintenance of the air intake vent is necessary when
In some situations such as when the vehicle is used frequently or in heavy
traffic or dusty areas, the air intake vent may need to be cleaned more regu-
larly. For details, refer to “Schedule maintenance guide” or “Owner’s Manual
Supplement”.
■Cleaning the air intake vent
●Dust in the air intake vent may interfere with the cooling of the hybrid battery
(traction battery). If charging/discharging of the hybrid battery (traction bat-
tery) becomes limited, the distance that the vehicle can be driven using the
electric motor (traction motor) may be reduced and the fuel economy may
be reduced.
●Improper handling of the air intake vent cover and filter may result in dam-
age to them. If you have any concerns about cleaning the filter, contact your
Toyota dealer.
■If “Maintenance Required for Traction Battery Cooling Parts See Owner’s
Manual” is displayed on the multi-information display
●If this warning message is displayed on the multi-information display,
remove the air intake vent cover and clean the filter. (P. 434)
●After cleaning the air intake vent, start the hybrid system and check that the
warning message is no longer displayed.
It may take approximately 20 minutes after the hybrid system is started until
the warning message disappears. If the warning message does not disap-
pear, have the vehicle inspected by your Toyota dealer.
WARNING
■When cleaning the air intake vent
●Do not use water or other liquids to clean the air intake vent. 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 vent, make sure to turn the power switch off
to stop the hybrid system.
■
When removing the air intake vent cover
Do not touch the service plug located near the air intake vent. (P. 82)

4386-3. Do-it-yourself maintenance
NOTICE
■When cleaning the air intake vent
■To prevent damage to the vehicle
●Do not allow water or foreign matter to enter the air intake vent when the
cover is removed.
●Carefully handle the removed filter so that it will not be damaged.
If the filter is damaged, have it replaced with a new filter by your Toyota
dealer.
●Make sure to reinstall the filter and cover to their original positions after
cleaning.
●Do not install anything to the air intake vent other than the exclusive filter

■If “Maintenance Required for Traction Battery Cooling Parts See
Owner’s Manual” is displayed on the multi-information display
If the vehicle is continuously driven with the warning message (indicating
that charging/discharging of the hybrid battery (traction battery) may
become limited) displayed, the hybrid battery (traction battery) may mal-
function. If a warning message is displayed, clean the air intake vent imme-
diately.
When cleaning the air intake vent, make
sure to only use a vacuum to suck out
dust and clogs. If a compressed air blow
gun, etc. is used to blow out dust and
clogs, the dust or clogs may be pushed
into the air intake vent, which may affect
the performance of the hybrid battery
(traction battery) and cause a malfunc-
tion.
