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 key (that
emits radio waves) is 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 vehicle’s electronic key or a wireless key that emits radio
waves
• Personal computers or personal digital assistants (PDAs)
• Digital audio players
• Portable game systems
●If window tint with a metallic con-
tent or metallic objects are

●When the electronic key is placed
near a battery charger or elec-
tronic devices
●When the vehicle is parked in a

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 or floor, or in the door
pockets or glove box when the
hybrid system is s tarted 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 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 effective range.
(The doors will au tomatically be
locked after approximately 60 sec-
onds 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 sensor
while wearing gloves may delay or
prevent lock operation. Remove
the gloves and touch the lock sen-
sor again.
●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

1683-2. Opening, closing and locking the doors
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 battery-
saving mode to disable the smart
key system. ( P.166)
●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 com es into contact
with ice, snow, mud, 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 approac h 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 the 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
●Vehicles with entry function: 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.542)
●Battery-saving mode can reduce
the power consumption of elec-
tronic keys. ( P.166)
■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.)

■Caution regarding interfer-
ence with electronic devices
●People with implantable car-
diac pacemakers, cardiac
resynchronization therapy-
pacemakers or implantable car-

( P.165)
The radio waves may affect the
operation of such devices. If
necessary, the entry function
can be disabled. Ask your
Toyota dealer for details, such
as the frequency of radio waves
and timing of the emitted radio
waves. Then, con sult your doc-
tor to see if you should disable
the entry function.
●User 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
for disabling the entry function.

■Power easy access system (if
equipped)
The driver’ seat and steering wheel
move in accordance with power
switch mode and the driver’ seat
belt condition. ( P.179)
■Jam protection function (vehi-
cles with driving position mem-
ory)
While the driving position is recalled
or the power easy access system is
operating, if an object is stuck
behind the front sea t, the front seat
will stop and then slightly move for-
ward.
When the jam protection function
operates, the seat stops at a posi-
tion other than the set seat position.
Check the seat position.
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 bel t during a colli-
sion, do not recline the seat
more than necessary.
If the seat is too reclined, the lap
belt may slide past the hips and
apply restraint forces directly to
the abdomen, or your neck may
contact the shoulder belt,
increasing 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.
●Manual seat only: After adjust-
ing the seat, make sure that the
seat is locked in position.

WARNING
■Seat adjustment
●Be careful that the seat does
not hit passengers or luggage.
●To reduce the risk of sliding
under the lap bel t during a colli-
sion, do not recline the seat
more than necessary. If the seat
is reclined too far, the lap belt
may slide past the hips and
apply restraint forces directly to
the abdomen, or your neck may
contact the shoulder belt,
increasing 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.
■When adjusting the seat posi-
tion or the ottoman (vehicles
with Ottoman seats)
Make sure to leave enough space
around the feet so as not to get
them caught.
■When using the ottoman
(vehicles with Ottoman seats)
●Do not sit on the ottoman. Seat
belts may not be properly worn
which may result in death or
serious injury.
●Stow the ottoman when you get
in and out of the vehicle or when
the ottoman is n ot in use to
avoid stumbling over it.
●Do not use the ottoman feature
when the vehicle is in motion.
The ottoman feature should
only be used when the vehicle
is stationary. If the ottoman fea-
ture is in use during an accident
the lap belt may slide past the
hips. This could also result in
restraint forces being applied to
the abdomen or your neck may
contact the shoulder belt,
increasing the risk of death or
serious injury.
