■The wireless charger can be
operated when
The engine switch is in ACC or ON.
■Portable devices that can be
charged
●Portable devices compatible with
the Qi wireless charging standard
can be charged by the wireless
charger. However, compatibility
with all devices which meet the Qi
wireless charging standard is not
guaranteed.
●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
compatible is attached. Depending
on the type of cover (including for
certain genuine manufacture parts)
and/or accessory attached, it may
not be possible to charge the porta-
ble 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 se conds. The fre-
quency 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 sus-
pended.
●While charging, the wireless char-
ger and the portable device will
become warm.
This is not a malfunction.If a porta-
ble device becomes warm while
charging and charging stops due
to the protection f unction of the
portable device, wait until the por-
table device cools down and
charge it again.
Blinks (orange) 3 times
repeatedly
A foreign object exists
between the portable
device and charging
area.
Remove the foreign
object.
Portable device is not
positioned properly on
the charging area.If there is a case or
cover attached to the
portable device, remove
it.
Blinks (orange) 4 times
repeatedlyThe temperature of the
wireless charger is
excessively high.
Stop charging, remove
the portable device from
the charging tray, wait
for the temperature to
drop, and then start
charging again.

■Routine tire inflation pressure
checks
The tire pressure warning system
does not replace routine tire inflation
pressure checks . Make sure to
check tire inflation pressure as part
of your routine o f daily vehicle
checks.
■Tire inflation pressure
●It may take a few minutes to dis-
play the tire inflation pressure
after the engine switch is turned to
ON. It may also take a few min-
utes to display the tire inflation
pressure after infl ation pressure
has been adjusted.
●Tire inflation pressure changes
with temperature.
The displayed values may also be
different from the values mea-
sured using a tire pressure gauge.
■Situations in which the tire
pressure warning system may
not operate properly
●In the following cases, the tire
pressure warning system may not
operate properly.
• If non-genuine Toyota wheels are used.
• A tire has been replaced with a
tire that is not an OE (Original
Equipment) tire.
• A tire has been replaced with a
tire that is not of the specified size.
• Tire chains, etc. are equipped.
• An auxiliary-support ed run-flat tire
is equipped.
• If a window tint that affects the radio wave signals is installed.
• If there is a lot of snow or ice on the vehicle, particularly around the
wheels or wheel housings.
• If the tire inflation pressure is extremely higher than the speci-
fied level.

Maintenance and care
• If tires not equipped with tire pres-sure warning valves and transmit-
ters are used.
• If the ID code on the tire pressure warning valves and transmitters is
not registered in the tire pressure
warning computer.
●Performance may be affected in
the following situations.
• Near a TV tower, electric power plant, gas station, radio station,
large display, airpo rt or other facil-
ity that generates strong radio
waves or electrical noise.
• When carrying a portable radio, cellular phone, cordless phone or
other wireless communication
device.
●When the vehicle is parked, the
time taken for the warning to start
or go off could be extended.
●When tire inflation pressure
declines rapidly for example when
a tire has burst, the warning may
not function.
■Warning performance of the tire
pressure warning system
The warning of the tire pressure
warning system will change in
accordance with driving conditions.
For this reason, the system may
give a warning even if the tire pres-
sure does not reach a low enough
level, or if the p ressure is higher
than the pressure that was adjusted
to when the system was initialized.
When replacing tires or wheels,
tire pressure warning valves and
transmitters must also be
installed.
When new tire pressure warning
valves and transmitters are installed, new ID codes must be
registered in the tire pressure
warning computer and the tire
pressure warning system must
be initialized. Have tire pressure
warning valves and transmitter
ID codes registered by your Toy-
ota dealer. (
P.293)
■Replacing tires and wheels
If the ID code of the tire pressure
warning valve and tr ansmitter is not
registered, the tire pressure warning
system will not work properly. After
driving for about 20 minutes, the tire
pressure warning light blinks for 1
minute and stays on to indicate a
system malfunction.

NOTICE
■Repairing or replacing tires,
wheels, tire pressure warn-
ing valves, transmitters and
tire valve caps
●When removing or fitting the
wheels, tires or the tire pressure
warning valves and transmit-
ters, contact your Toyota dealer
as the tire pressure warning
valves and transmitters may be
damaged if not handled cor-
rectly.
●Make sure to install the tire
valve caps. If the tire valve caps
are not installed, water could
enter the tire pressure warning
valves and the tire pressure
warning valves could be bound.
●When replacing tire valve caps,
do not use tire valve caps other
than those specified. The cap
may become stuck.

●Ne placez rien sur le siège du
passager avant, comme un
coussin par exemple. Cela a
pour conséquence de répartir le
poids du passager sur toute la
surface du siège, ce qui

correctement le poids du pas-
sager. En conséquence, les
coussins gonflables frontaux
SRS du passager avant ris-
quent de ne pas se déployer en
cas de collision.
