■When riding in an aircraft
When bringing an electronic key
onto an aircraft, make sure you do
not press any buttons on the elec-
tronic key while inside the aircraft
cabin. If you are carrying an elec-
tronic key in your bag, etc., ensure
that the buttons are not likely to be
pressed accidentally. Pressing a
button may cause the electronic key
to emit radio waves that could inter-
fere with the oper ation of the air-
craft.
■Electronic key battery depletion
●The standard battery life is 1 to 2
years.
●If the battery becomes low, an
alarm will sound in the cabin and a
message will be s hown on the
multi-information display when the fuel cell system is stopped.
●To reduce key battery depletion
when the electronic key is to not
be used for long periods of time,
set the electronic key to the bat-
tery-saving mode. (
P.137)
●As the electronic key always
receives radio waves, the battery
will become depleted even if the
electronic key is not used. The fol-
lowing symptoms indicate that the
electronic key battery may be
depleted. Replace the battery
when necessary.
• The smart key system or the wire- less remote contro l does not oper-
ate.
• The detection area becomes smaller.
• The LED indicator on the key sur- face does not turn on.
●To avoid serious deterioration, do
not leave the electronic key within
3 ft. (1 m) of the following electri-
cal appliances that produce a
magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cordless phones
• Table lamps
• Induction cookers

■Confirmation of the number of
registered keys
The number of keys already regis-
tered to the vehi cle can be con-
firmed. Ask your Toyota dealer for
details.

netic materials to the keys or
place the keys close to such
materials.
●Do not disassemble the keys.
●Do not attach a sticker or any-
thing else to the surface of the
electronic key.
●Do not place th e keys near
objects that produce magnetic
fields, such as TVs, audio sys-
tems and induction cookers, or

such as low-frequency therapy
equipment.
■Carrying the electronic key
on your person
Carry the electronic key 3.9 in.
(10 cm) or more away from elec-
tric appliances that are turned on.

appliances within 3.9 in. (10 cm)
of the electronic key may interfere
with the key, causing the key to
not function properly.

●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

doors detecting the electronic key
can be used to unl ock the vehicle.
●Even if the electronic key is not
inside the vehicle, it may be possi-
ble to start the fuel cell system if
the electronic key is near the win-
dow.
●The doors may unlock or lock if a
large amount of water splashes on
the door handle, such as in the
rain or in a car wash, when the
electronic key is within the effec-
tive range. (The doors will auto-
matically be locked after
approximately 60 seconds if the
doors are not opened and closed.)
●If the wireless remote control is
used to lock the doors when the
electronic key is near the vehicle,
there is a possib ility that the door
may not be unlocke d by the entry
function. (Use the wireless remote
control to unloc k the doors.)
●Touching the door lock sensor
while wearing gloves may delay or
prevent lock operation.
●When the lock op eration is per-
formed using the lock sensor, rec-
ognition signals will be shown up
to two consecutive times. After
this, no recogniti on signals will be
given.
●If the door handle becomes wet
while the electronic key is within
the effective ran ge, the door may
lock and unlock repeatedly. In this
case, follow the fo llowing correc-
tion procedures to wash the vehi-
cle:
• Place the electronic key in a loca- tion 6 ft. (2 m) or more away from
the vehicle. (Take care to ensure
that the key is not stolen.)
• Set the electronic key to battery- saving mode to disable the smart
key system. ( P.137)
●If the electronic key is inside the
vehicle and a door handle
becomes wet during a car wash, a
message may be shown on the
multi-informatio n display and a buzzer will sound outside the vehi-
cle. To turn off the alarm, lock all
the doors.
●The lock sensor may not work
properly if it comes into contact
with ice, snow, m
ud, etc. Clean
the lock sensor and attempt to
operate it again.
●A sudden approach to the effec-
tive range or door handle may pre-
vent the doors from being
unlocked. In this case, return the
door handle to the original position
and check that t he doors unlock
before pulling the door handle
again.
●If there is another electronic key in
the detection area, it may take
slightly longer to unlock the doors
after the door handle is gripped.
■When the vehicle is not driven
for extended periods
●To prevent theft of the vehicle, do
not leave the electronic key within
6 ft. (2 m) of the vehicle.
●The smart key system can be
deactivated in advance.
●Setting the electronic key to bat-
tery-saving mode helps to reduce
key battery depletion. ( P.137)
■To operate the system properly
●Make sure to carry the electronic
key when operating the system.
Do not get the electronic key too
close to the vehicle when operat-
ing the system from the outside of
the vehicle.
Depending on the position and hold-
ing condition of the electronic key,
the key may not be detected cor-
rectly and the system may not oper-
ate properly. (The alarm may go off
accidentally, or the door lock pre-
vention function m ay not operate.)

WARNING
■When adjusting the seat posi-
tion
●Take care when adjusting the
seat position to ensure that
other passengers are not
injured by the moving seat.
●Do not put your hands under the
seat or near the moving parts to
avoid injury.
Fingers or hands may become
jammed in the seat mechanism.
●Make sure to leave enough
space around the feet so they
do not get stuck.
■Seat adjustment
To reduce the risk of sliding under
the lap belt during a collision, do
not recline the se at more than
necessary.
If the seat is too reclined, the lap
belt may slide past the hips and
apply restraint for ces directly to
the abdomen, or your neck may
contact the shoulder belt, increas-
ing the risk of death or serious
injury in the event of an accident.
Adjustments should not be made
while driving as the seat may
unexpectedly move and cause
the driver to lose control of the
vehicle.
