■Battery-saving function
In the following circumstances, the entry function is disabled in order to pre-
vent the vehicle battery from discharging and the electronic key battery from

Conditions aff ecting 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 and wireless remote control from
operating properly. (Ways of coping P. 400)
● 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 carrying a portable radio, ce llular phone, cordless phone or other
wireless communication device
● When the electronic key is in contact with, or is covered by the following
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 multiple electronic keys are in the vicinity
● When another wireless key (that emits radio waves) is being used nearby
● When carrying or using the electronic key together with the following
devices that emit radio waves
• Another vehicle’s electronic key
• 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

■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, floor or in the glove box when the engine is started or “ENGINE START STOP” 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 outside 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.
● 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 within the effective range. (The doors will automatically 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 elec-
tronic key is near the vehicle, there is a possibility that the door may not
be unlocked by the smart key system. (Use the wireless remote control to
unlock the doors.)

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 door handle becomes wet while the electronic key is within the
effective range, the door may lock and unlock repeatedly. Place the key
in a position 6 ft. (2 m) or more separate from the vehicle while the vehi-
cle is being washed. (Take care to ensure that the key is not stolen.)
● 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.
● The lock sensor may not work properly if it comes 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.

Scion_tC_U_(OM21041U)
■Notes for the unlocking function
● Gripping the side door handle when wearing a glove may not unlock or
lock the door.
● A sudden approach to the effective range or door handle operation may
prevent the doors from being unlocked. In this case, return the door han-
dle to the original position and check that the doors have unlocked before
pulling the door handle.
● If there is another electronic key in the detection area, it may take slightly
longer to unlock the doors after one of the side door handles are 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. Contact your
Scion dealer for details.
■ 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
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 may not
operate.)
■ If the smart key system does not operate properly
● Locking and unlocking the doors: Use the mechanical key. ( P. 400)
● Starting the engine ( P. 401)

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
engine stops. ( P. 38)
● 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. 326)
• 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
• Recharging cellular phones or cordless phones
• Cellular phones, cordless phones and battery chargers
• Glass top ranges
