■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 when
the hybrid 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.147)
●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
■Replacing the battery
 P.438
■Confirmation of the registered
key number
The number of keys already regis-
tered to the vehi cle can be con-
firmed. Ask your Toyota dealer for
details.
■If “A New Key has been Regis-
tered Contact Your Dealer for

The mechanical key can only be
inserted in one direction, as the key
only has grooves on one side. If the
key cannot be inserted in a lock cyl-
inder, turn it over and re-attempt to
insert it.
After using the mechanical key,
store it in the electronic key. Carry
the mechanical k ey together with
the electronic key. If the electronic
key battery is dep leted or the entry
function does not operate properly,
you will need the m echanical key.

■Rear seat reminder function
In order to remind you not to forget
luggage, etc. in the rear seat, when
the power switch is turned off after
any of the following conditions are
met, a buzzer will sound and a mes-
sage will be displayed on the
multi-information di splay for approx-
imately 6 seconds.
●The hybrid system is started
within 10 minutes after opening
and closing a rear door.
●A rear door has been opened and
closed after the hybrid system
was started.
However, if a rear door is opened
and then closed within approxi-
mately 2 seconds , the rear seat
reminder function may not operate.
The rear seat reminder function
determines that luggage, etc. has
been placed in a rear seat based on
opening and closing of a rear door.
Therefore, depending on the situa-
tion, the rear seat reminder function
may not operate and you may still
forget luggage, etc. in the rear seat,
or it may operate unnecessarily.
The rear seat reminder function can
be enabled/disabled. ( P.526)

■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 hybrid 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 door 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 unlock the vehicle.
●Even if the electro
nic key is not
inside the vehicle, it may be possi-
ble to start the hybrid system if the
electronic key is near the window.
●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 unlocked by the entry
function. (Use the wireless remote
control to unlock the doors.)
●Touching the door lock or unlock
sensor while wearing gloves may
prevent lock or unlock operation.
●When the lock operation is per-
formed using the lock sensor, rec-
ognition signals will be shown up
to two consecutive times. After
this, no recognition signals will be
given.
●If the door handle becomes wet
while the electronic key is within
the effective range, the door may
lock and unlock repeatedly. In that
case, follow the following 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 bat-
