Alarms and warning indicators
A combination of exterior and interior alarms as well as warnin g messages
shown on the multi-information display is used to prevent theft of the vehicle
and accidents resulting from erroneous operation. Take appropriate mea-
sures in response to any warning message on the multi-information display.
( P. 489)
The following table describes circumstances and correction procedures when
only alarms are sounded.
■ Battery-saving function
The battery-saving function will be activated in order to preve nt the electronic
key battery and the 12-volt battery from being discharged while the vehicle is
not in operation for a long time.
● In the following situations, the smart key system may take some time to
unlock the doors.
• The electronic key has been left in an area of approximately 6 ft. (2 m) of
the outside of the vehicle for 10 minutes or longer.
• The smart key system has not been used for 5 days or longer.
● If the smart key system has not been used for 14 days or longer , the doors
cannot be unlocked at any of the doors except the driver’s door . In this case,
take hold of the driver’s door handle, or use the wireless remote control or
the mechanical key, to unlock the doors.
■ Electronic key battery-saving function
When battery-saving mode is set, battery depletion is minimized by stopping
the electronic key from receiving radio waves.

Conditions affecting operation
The smart key system uses weak radio waves. In the following si tuations, 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. 520)
● When the electronic key battery is depleted
● Near a TV tower, electric power plant, gas station, radio stati on, large dis-
play, airport or other facility that generates strong radio wav es or electrical
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 wire less 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 ele ctronic
devices

Notes for the entry function
●Even when the electronic key is within the effective range (det ection 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 unl ocked.
• The electronic key is on the instrument panel, luggage cover o r 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 i nstrument
panel or near the door pockets. Depending on the radio wave reception con-
ditions, 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, th e doors may be
locked or unlocked by anyone. However, only the doors detecting the elec-
tronic key can be used to unlock the vehicle.
● Whether or not the electronic key is inside the vehicle, the hy brid 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 han-
dle, such as in the rain or in a car wash when the electronic k ey is within the
effective range. (The door will automatically be locked after a pproximately
60 seconds if the doors are not opened and closed.)
● The lock and unlock sensors may not work properly if they come into con-
tact with ice, snow, mud, etc. Clean the sensors and attempt to operate
them again.
● If the wireless remote control is used to lock the doors when t he electronic
key is near the vehicle, there is a possibility that the door m ay not be
unlocked by the entry function. (Using the wireless remote cont rol to unlock
the doors may resume the function.)
● If the door handle becomes wet while the electronic key is with in the effec-
tive range, the door may lock and unlock repeatedly. In that ca se, follow the
following correction procedures to wash the vehicle:
• Place the electronic key in a location 6 ft. (2 m) or more awa y from the
vehicle. (Take care to ensure that the key is not stolen.)
• Set the electronic key to battery-saving mode to disable the s mart key
system. ( P. 142)

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 aga in.
● When the lock operation is performed using the lock sensor, rec ognition sig-
nals will be shown up to two consecutive times. After this, no recognition
signals will be given.
● If the electronic key is inside the vehicle and a door handle b ecomes wet
during a car wash, a buzzer will sound outside the vehicle. To turn off the
alarm, lock all the doors.
■ Notes for the un locking 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 origi-
nal position and check that the doors unlock before pulling the door handle
again.
● Gripping the door handle when wearing a glove may not unlock th e 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 ma y take slightly
longer to unlock the doors after the door handle is gripped.
■ When the vehicle is not driven for extended periods
●To prevent theft of the vehicle, do not leave the electronic ke y within 6 ft. (2
m) of the vehicle.
● The smart key system can be deactivated in advance. Ask your To yota
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 electron ic key, the key
may not be detected correctly and the system may not operate pr operly. (The
alarm may go off accidentally, or the door lock prevention func tion may not
operate.)

WARNING
■Caution regarding interfer ence with electronic devices
● People with implantable cardiac pacemakers, cardiac resynchroni zation
therapy-pacemakers or implantable cardioverter defibrillators s hould keep
away from the smart key system antennas. ( P. 141)
The radio waves may affect the operation of such devices. If ne cessary,
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 entr y function.
● User of any electrical medical device other than implantable ca rdiac pace-
makers, cardiac resynchronization therapy-pacemakers or implant able
cardioverter defibrillators should consult the manufacturer of the device for
information about its operation under the influence of radio wa ves.
Radio waves could have unexpected effects on the operation of such
medical devices.
Ask your Toyota dealer for details for disabling the entry func tion.
