Installation of a mobile two-way radio system
The installation of a mobile two-way radio system in your vehicle could affect
electronic systems such as:
●Multi-port fuel injection system/sequential multi-port fuel injection system
● Cruise control system
● Anti-lock brake system
● SRS airbag system
● Seat belt pretensioner system
Be sure to check with your Scion dealer for precautionary measures or spe-
cial instructions regarding installation of a mobile two-way radio system.

tC_OM_OM21042U_(U)
■When required to leave the vehic le’s key with a parking attendant
Lock the glove box as circumstances demand. ( P. 252)
On vehicles without the smart key system, provide the attendant with the
valet key. 
On vehicles with the smart key system, remove the mechanical key for your
own use and provide the attendant with the electronic key only.
■ Key number plate
Keep the plate in a safe place such as your wallet, not in the vehicle. In the
event that a key (without a smart key system) or mechanical key (with a
smart key system) is lost, a new key can be made by your Scion dealer
using the key number plate. ( P. 404)
■ When riding in an aircraft
When bringing a key with wireless remote control function onto an aircra\
ft,
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 a\
ircraft.

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. 405)
● 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

tC_OM_OM21042U_(U)
■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.)

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. 330)
• 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
• Table lamps

CAUTION
■
Caution regarding interfer ence with electronic devices
● People with implanted pacemakers or cardiac defibrillators should keep
away from the smart key system antennas. ( P. 36)
The radio waves may affect the operation of such devices. If necessary,
the entry function can be disabled. Ask your Scion dealer for details, such
as the frequency of radio waves and timing of emitting the radio waves.
Then, consult your doctor to see if you should disable the entry function.
● Users of any electrical medical device other than implanted pacemakers
and implanted cardiac defibrillators should consult the manufacturer of the
device for information about its operation under the influence of radio
waves. Radio waves could have unexpected effects on the operation of
such medical devices.
Ask your Scion dealer for details for disabling the entry function.
