■Conditions affecting operation
The smart key system uses weak 
radio waves. In the following situa-
tions, 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.527)
●When the electronic key battery is 
depleted
●Near a TV tower, electric power 
plant, gas station , radio station, 
large display, airpo rt or other facil-
ity that generates strong radio 
waves or electrical noise
●When carrying a portable radio, 
cellular phone, cordless phone or 
other wireless communication 
device
●When the electronic key is in con-
tact with, or is covered by the fol-
lowing metallic objects
• Cards to which al uminum foil is 
attached
• Cigarette boxes that have alumi- num 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
• Another electronic key or a wire- less key that emits radio waves
• Personal computers or personal 
digital assistants (PDAs)
• Digital audio players
• Portable game systems
●If window tint with a metallic con-
tent or metallic objects are 
attached to the rear window
●When the electronic key is placed 
near a battery charger or elec-
tronic devices
●When the vehicle is parked in a 
pay parking spot where radio 
waves are emitted.
■Note for the entry function
●Even when the electronic key is 
within the effective range (detec-
tion areas), the system may not 
operate properly in the following 
cases:
• The electronic key is too close to  the window or outside door han-
dle, near the ground, or in a high 
place when the doors are locked 
or unlocked.
• The electronic key is near the 
ground or in a high place, or too 
close to the center of the rear 
bumper.
• The electronic key is on the instru- ment panel, or floor, or in the door 
pockets or glove box when the 
hybrid system is started or power 
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 out-
side the cabin and the doors 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.
●Even if the electro nic key is not 
inside the vehicle, it may be possi-
ble to start the hybrid system if the 
electronic key is near the window.
●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 effec-
tive range. (The  doors will auto-
matically be locked after 
approximately 60 seconds if the

WARNING
■Caution regarding interfer-
ence with electronic devices
●People with implantable car-
diac pacemakers, cardiac 
resynchronization therapy-
pacemakers or implantable car-
dioverter defibrillators should 
keep away from the smart key 
system antennas. ( P.128)
The radio waves may affect the 
operation of such devices. If 
necessary, the entry function 
can be disabled. Ask your Toy-
ota dealer for details, such as 
the frequency of radio waves 
and timing of the emitted radio 
waves. Then, consult your doc-
tor to see if you should disable 
the entry function.
●Users of any electrical medical 
device other than implantable 
cardiac pacemakers, cardiac 
resynchronization therapy-
pacemakers or implantable car-
dioverter defibrillators should 
consult the manufacturer of the 
device for information about its 
operation under the influence of 
radio waves.
Radio waves could have unex-
pected effects on  the operation 
of such medical devices.
Ask your Toyota dealer for details 
on disabling the entry function.
