■When riding in an aircraft (with
a wireless remote control func-
tion)
When bringing a ke y with wireless
remote control func tion onto an air-
craft, make sure you do not press
any buttons on the key while inside
the aircraft cabin. If you are carrying
the key in your bag, etc., ensure that
the buttons are not likely to be
pressed accidentally. Pressing a
button may cause the key to emit
radio waves that could interfere with
the operation of the aircraft.
■Key battery depletion (with a
wireless remote control func-
tion)
Vehicles without a smart key sys-
tem
●The standard battery life is 1 to 2
years.
●The battery will be come depleted
even if the key is not used. The
following symptoms indicate that
the key battery may be depleted.
Replace the battery when neces-
sary. ( P.333)

Before driving
• The wireless remote control does not operate.
• The detection area becomes
smaller.
Vehicles with a smart key system
●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 shown on the
multi-information display when the
engine 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.121)
●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. ( P.333)
• The smart key system or the wire- less remote control 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 t hat produce a
magnetic field:
• TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or
cordless phones
• Table lamps
• Induction cookers
●If the electronic key is near the
vehicle for longer than necessary,
even if the smart key system is not
operated, the key battery may
become depleted faster than nor-
mal.
■Replacing the battery (with a
wireless remote control func-
tion)
 P.333
■The electronic key function is
suspended when (vehicles with
a smart key system)
The electronic key function may be
suspended when the electronic key
is kept unmoved in a same location
for a certain period, such as it is left
on a same place. This is to reduce
battery consumption. The function
will be restored automatically when
the electronic key is moved, such as
it is picked up.
■If “A New Key has been Regis-
tered Contact Your Dealer for
Details” is shown on the
multi-information display (vehi-
cles with a smart key system)
This message will be displayed
each time the driver’s door is
opened when the doors are
unlocked from the outside for
approximately 10 days after a new
electronic key has been registered.
If this message is displayed but you
have not had a new electronic key
registered, ask your Toyota dealer to
check if an unknown electronic key
(other than those in your posses-
sion) has been registered.
■If a wrong key is used (with a
wireless remote control func-
tion)
The key cylinder rotates freely, iso-
lated from the internal mechanism.
NOTICE
■To prevent key damage
●Do not drop the keys, subject
them to strong shocks or bend
them.
●Do not expose the keys to high
temperatures for long periods of
time.

■Rear seat reminder function
In order to remind you not to forget
luggage, etc. in the rear seat, when
the engine 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 engine is started within
approximately 10 minutes after
opening and closing a rear door.
●A rear door has been opened and
closed after the engine 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 rem inder 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.
■Customization
Some functions can be customized.

resulting in death o r serious injury.
●Ensure that all doors are prop-
erly closed and locked.
●Do not pull the inside door han-
dle while driving.
Be especially careful of the front
doors, as the doors may be
opened even if the inside lock
buttons are in the locked posi-
tion.
●Set the rear door child-protector
locks when children are seated
in the rear seats.
■When opening or closing a
door
Check the surroundings of the
vehicle such as wh ether the vehi-
cle is on an incline, whether there
is enough space for a door to
open and whether a strong wind
is blowing. When opening or clos-
ing the door, hold the door handle

1223-2. Opening, closing and locking the doors
●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 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
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
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.382)
If the engine cannot be started using
the smart key system, refer to
P.382.
■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 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-
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 engine if the elec-
tronic key is near the window.
●The doors may unlock or lock if a
large amount of water splashes on
