■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-

1343-2. Opening, closing and locking the doors
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 electronic key is not
inside the vehicle, it may be possi-
ble to start the engine if the elec-
tronic 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 w ithin 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 or unlock
sensor while wearing gloves may
prevent lock or unlock 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 that
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 bat- tery-saving mode to disable the
smart key system. (
P.133)
●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-information 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, or use the lock
sensor on the lower part of the
door handle.
●A sudden handle operation or a
handle operation immediately
after entering the effective range
may prevent the doors from being
unlocked. Touch the door unlock
sensor and check that the doors
are unlocked befo re 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. ( P.494)
●Setting the electronic key to bat-
tery-saving mode helps to reduce
key battery depletion. ( P.133)
■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 operating the
system from the out side of the vehi-
cle.
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 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.
