■Turning an electronic key to
battery-saving mode
●When battery-saving 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 electronic key indi-
cator flashes 4 times.
While the battery-saving mode is

■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.504)
●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 c overed by the fol-
lowing metallic objects
• Cards to which aluminum 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

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 parking in a coin-operated
parking lot (Radio waves used to
detect vehicles may affect the
smart key system.)
■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

Before driving
hybrid system 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 unl ock the vehicle.
●Even if the electronic 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 automatically 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 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. Remove
the gloves and touch the lock sen-
sor again.
●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 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 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-information display and a
buzzer will sound outside the vehi-
cle. To turn off th e 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 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
●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.544)
●Battery-saving mode can reduce
the power consumption of elec-
tronic keys. ( P.166)
