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, wireless remote control and
immobilizer system from operating properly. (Way of coping P. 621)
● 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, mobile phone, cordless phone or other
wireless communication device
● 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 multiple electronic keys are in the vicinity
● 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 content or metallic objects are attached to
the back window

■Note 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 or floor, in the glove box, or in the auxiliary box of the instrument panel.
● 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 lock or unlock if the electronic key is within the effective
range and a large amount of water splashes on the door handle, such as
in the rain or in a car wash. The doors will automatically be locked after
approximately 60 seconds if a door is 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 entry function. (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.
● Fingernails may scrape against the door during operation of the door
handle. Be careful not to injure fingernails or damage the surface of the
door.
■ Notes for the unlocking function
● Gripping the door handle when wearing a glove may not unlock the door.
● 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.
● 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.
■ 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
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. 621)
● Starting the engine: P. 622

■Electronic key battery depletion
● The standard battery life is 1 to 2 years.
● 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. 552)
• 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
• Glass top ranges
• Table lamps
■ Precautions when disc onnecting the battery
● In some cases, it may not be possible to unlock the doors using the smart
key system immediately after the battery has been disconnected. Use
the wireless remote control or the mechanical key to lock or unlock the
doors.
● The engine may not start on the first attempt after reconnecting the bat-
tery but will start normally after the second attempt. This is not a malfunc-
tion.
● The “ENGINE START STOP” switch mode is memorized by the vehicle.
When the battery is reconnected, the system will return to the mode it
was in before the battery was disconnected. Before disconnecting the
battery, turn the “ENGINE START STOP” switch off.
If you are unsure what mode the “ENGINE START STOP” switch was in
when the battery was disconnected, be especially careful when reconnect-
ing the battery.

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. 38)
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 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 Toyota dealer for details on disabling the entry function.
