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 indicator flashes 4 times.

Conditions affecting operation
The smart key system uses weak radio waves. In the following situations,
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. 479)
● When the electronic key battery is depleted
● Near a TV tower, electric power plant, gas station, radio station, large dis-
play, airport or other facility that generates strong radio waves or electri-
cal noise
● When the electronic key is in contact with, or is covered by the following
metallic objects
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum 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
• A portable radio, cellular phone, cordless phone or other wireless com-
munication device
• 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 content or metallic objects are attached to
the rear window
● When the electronic key is placed near a battery charger or electronic
devices

56 1-3. Opening, closing and locking the doors
■Notes for the entry function
●Even when the electronic key is within the effective range (detection
areas), the system may not operate properly in the following cases:
• The electronic key is too close to the window or outside door handle,
near the ground, or in a high place when the doors are locked or
unlocked.
• The electronic key is on the instrument panel, luggage cover or floor, in the door pockets or glove box when the hybrid system is started or
“POWER” switch modes are changed.
● Do not exit the vehicle with the electronic key placed on the instrument
panel or near the door pockets. Depending on the radio wave reception
conditions, it may be detected by the antenna outside the cabin and the
door will become lockable from the outside, possibly trapping the elec-
tronic key inside the vehicle.
● As long as the electronic key is within the effective range, the doors may
be locked or unlocked by anyone.
● Whether or not the electronic key is inside the vehicle, the hybrid system
could be started 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 door will automatically be locked after
approximately 60 seconds if the doors are not opened and closed.)
● The lock and unlock sensors may not work properly if they come into
contact with ice, snow, mud, etc. Clean the sensors and attempt to oper-
ate them again.
● If the wireless remote control is used to lock the doors when the elec-
tronic key is near the vehicle, there is a possibility that the door may not
be unlocked by the entry function. (Using the wireless remote control to
unlock the doors may resume the function.)
● 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 correction procedures to wash the vehicle:
• Place the electronic key in a location 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. 54)

Notes for locking the doors
●Touching the door lock sensor while wearing gloves may delay or prevent
lock operation. Remove the gloves and touch the lock sensor again.
● When the lock operation is performed using the lock sensor, recognition
signals will be shown up to two consecutive times. After this, no recogni-
tion signals will be given.
● If the electronic key is inside the vehicle and a door handle becomes wet
during a car wash, a buzzer will sound outside the vehicle. To turn off the
alarm, lock all the doors.
■ Notes for the unlocking function
●A sudden approach to the effective range or door handle may prevent 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.
● Gripping the door handle when wearing a glove may not unlock the door.
Remove the gloves and touch the sensor on the back of the 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 dr iven 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. Ask your Toyota
dealer for details.
■ To operate the smart key 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 outside of the vehicle.
Depending on the position and holding condition of the electronic key, the
key may not be detected correctly and the system may not operate properly.
(The alarm may go off accidentally, or the door lock prevention function may
not operate.)
■ If the smart key system does not operate properly
● Locking and unlocking the doors: Use the mechanical key. ( P. 479)
● Starting the hybrid system: P. 479

■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 stops. (P. 455)
● As the electronic key always receives radio waves, the battery will
become depleted even if the electronic key is not used. The following
symptoms indicate that the electronic key battery may be depleted.
Replace the battery when necessary. ( P. 401)
• The smart key system or the wireless remote control does not operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.
● To avoid serious deterioration, do not leave the electronic key within 3 ft.
(1 m) of the following electrical appliances that produce a magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cordless phones
• Induction cookers
• Table lamps
■ When the electronic key battery is fully depleted
P. 401
■ If the smart key system has been d eactivated in a customized setting
● Locking and unlocking the doors: Use the wireless remote control or
mechanical key. ( P. 61, 479)
● Starting the hybrid system and changing “POWER” switch modes:
P. 479
● Stopping the hybrid system: P. 480
■ Customization that can be co nfigured at Toyota dealer
Settings (e. g. operation signals) can be changed.

CAUTION
■Caution regarding interfer ence with electronic devices
● People with implantable cardiac pacemakers, cardiac resynchronization
therapy-pacemakers or implantable ca rdioverter defibrillators should keep
away from the smart key system antennas. ( P. 50)
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, consult your doctor to see if you should disable the entry function.
