1384-2. Opening, closing and locking the doors and trunk
Owners Manual_USA_M62064_en
●Electronic keys that will not be
used for long periods of time can
be set to the battery-saving mode
in advance.
■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 immobilizer system from
operating properly. (Ways of coping:
 P.482)
●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 carrying a portable radio,
cellular phone, cordless phone or
other wireless communication
device
●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 wireless keys (that
emit radio waves) are being used
nearby
●When carrying the electronic key
together with the following devices that emit radio waves
• 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 near the ground or in a high place, or too
close to the center of the rear
bumper when the trunk is opened.
• The electronic key is on the instru- ment panel, rear package tray or
floor, or in the door pockets or
glove box when the fuel cell sys-
tem is started or power 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-
side the cabin and the doors will
become lockable from the outside,
possibly trapping the electronic
key inside the vehicle.
●As long as the electronic key is
within the effective range, the
doors may be locked or unlocked
by anyone. However, only the

WARNING
■Caution regarding interfer-
ence with electronic devices
●People with implantable car-
diac pacemakers, cardiac
resynchronization therapy-
pacemakers or implantable car-
dioverter defibrillators should
keep away from the smart key
system antennas. ( P.136)
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 therapy-
pacemakers or implantable car-
dioverter defibrillators should
consult the manufacturer of the
device for information about its
operation under the influence of
radio waves.
Radio waves could have unex-
pected effects on the operation
of such medical devices.
Ask your Toyota dealer for details
on disabling the entry function.
