mechanical key, to unlock the
doors.
■Turning an electronic key to
battery-saving mode
When battery-savi ng mode is set,
battery depletion is minimized by
stopping the electronic key from
receiving radio waves.
Press twice while pressing and
holding . Confirm that the elec-
tronic key indicator flashes 4 times.
While the battery-saving mode is
set, the smart key system cannot be
used. To cancel the function, press
any of the electronic key buttons.
■Conditions affecting operation
The smart key system uses weak
radio waves. In the following situa-
tions, the communication between
the electronic key and the vehicle
may be affected, preventing the
smart key system, wireless remote
control and engine immobilizer sys-
tem from operating properly. (Ways
of coping: P.463)
●When the electronic key battery is
depleted
●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 the electronic key is in con-
tact with, or is covered by the fol-
lowing metallic objects
• Cards to which al uminum foil is
attached
• Cigarette boxes that have alumi- num foil inside • Metallic wallets or bags
•Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
●When other wirel
ess keys (that
emit radio waves) are being used
nearby
●When carrying the electronic key
together with the following devices
that emit radio waves
• Portable radio, cellular phone, cordless phone or other wireless
communication devices
• Another electronic key or a wire- less key that emits radio waves
• Personal computers or personal
digital assistants (PDAs)
• Digital audio players
• Portable game systems
●If window tint wit h a metallic con-
tent or metallic objects are
attached to the rear window
●When the electronic key is placed
near a battery charger or elec-
tronic devices
●When the vehicle is parked in a
pay parking spot where radio
waves are emitted
■Note for the entry function
●Even when the electronic key is
within the effective range (detec-
tion areas), the system may not
operate properly in the following
cases:
• The electronic key is too close to the window or outside door han-
dle, near the ground, or in a high
place when the doors are locked
or unlocked.
• The electronic key is on the instru-
ment panel, luggage compart-
ment, floor, or in the door pockets
or glove box when the engine is
started or engine switch modes
are changed.
●Do not leave the electronic key on
top of the instrument panel or near
the door pockets when exiting the
vehicle. Depending on the radio
wave reception conditions, it may
be detected by the antenna out-

rectly and the system may not oper-
ate properly. (The alarm may go off
accidentally, or the door lock pre-
vention may not operate.)
■If the smart key system does
not operate properly
If the doors cannot be
locked/unlocked using the smart key
system, lock/unlock the doors by
performing any of the following:
●Bring the electronic key close to
either front door handle and oper-
ate the entry function.
●Operate the wireless remote con-
trol.
If the doors cannot be
locked/unlocked using the above
methods, use the mechanical key.
(  P.463)
If the engine cannot be started using
the smart key system, refer to
P.464.
■Customization
Some functions can be customized.
(  P.494)
■If the smart key system has
been deactivated in a custom-
ized setting
●Locking and unlocking the doors:
Use the wireless remote control or
mechanical key. ( P.115, 463)
●Starting the engine and changing
engine switch modes: P. 4 6 4
●Stopping the engine: P. 1 9 8
WARNING
■Caution regarding interfer-
ence with electronic devices
●People with implantable car-
diac pacemakers, cardiac
resynchronization ther-
apy-pacemakers or implantable
cardioverter defibrillators should
keep away from the smart key
system antennas. ( P.131) The
radio waves may affect the
operation of such devices. If
necessary, the entry function
can be disabled. Ask your Toy-
ota dealer for details, such as
the frequency of radio waves
and timing of the emitted radio
waves. Then, consult your doc-
tor to see if you should disable
the entry function.
●Users of any electrical medical
device other than implantable
cardiac pacemakers, cardiac
resynchronization ther-
apy-pacemakers or implantable
cardioverter defibrillators should
consult the manufacturer of the
device for information about its
operation under the influence of
radio waves. Radio waves could
have unexpected effects on the
operation of such medical
devices.
Ask your Toyota dealer for details
on disabling the entry function.

■AM radio cooperation function
during charging
●When noise enters the AM radio
during charging, charging fre-
quency will be automatically
changed to reduce noise.
●While the AM radio automatic tun-
ing, charging is temporarily
stopped in order to prevent tuning
error due to noise caused by
charging. When tuning is finished,
charging will be automatically
resumed.
■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 mal-
function. If a portable device
becomes warm while charging
and charging stops due to the pro-
tection function of the portable
device, wait until the portable
device cools down and charge it
again.
The fan may start operating to
lower the temperature inside the
wireless charger, however this is
not a malfunction.
■Sound generated during opera-
tion
When the power su pply switch is
turned on or while a portable device
is being identified, operation sounds
may be heard. This is not a malfunc-
tion.
■Cleaning the wireless charger
 P. 3 7 3
WARNING
■Caution while driving
When charging a portable device,
for safety reasons, the driver
should not operate the main part
of the portable device while driv-
ing.
■Caution while in motion
Do not charge lightweight devices
such as wireless headphones
while in motion. These devices
are very light and may be ejected
from the charging tray, which may
lead to unforeseen accidents.
■Caution regarding interfer-
ence with electronic devices
People with implantable cardiac
pacemakers, cardiac resynchroni-
zation therapy pacemakers or
implantable cardioverter def ibrilla-
tors, as well as any other electri-
cal medical device, should consult
their physician about the usage of
the wireless charger.
■To prevent malfunctions or
burns
Observe the following precau-
tions.
Failure to do so may result in an
equipment failure and damage,
catch fire, burns due to overheat
or electric shock.
●Do not insert any metallic
objects between the charging
area and the portable device
while charging.
●Do not attach a n aluminum
sticker or other metallic objects
to the charge area.
●Do not attach a n aluminum
sticker or other metallic objects
to the side of the portable
device (or to its case or cover)
that touches the charge area.
