that emit radio waves
• Portable radio, cellular phone,  cordless phone or other wireless 
communication devices
• Another electronic key or a wire- less key that emits radio waves

■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 on the instru-
ment panel, luggage compart-
ment, floor, or in the door pockets 
or glove box when the hybrid sys-
tem 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 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.
●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 
doors are not opened and closed.)
●If the wireless remote control is 
used to lock the doors when the 
electronic key is near the vehicle, 
there is a possib ility that the door 
may not be unlocked by the entry 
function. (Use the wireless remote 
control to unlock the doors.)
●Touching the door lock or unlock 
sensor while wearing gloves may 
prevent lock or unlock operation.
●When the lock operation is per-
formed using the lock sensor, rec-
ognition signals will be shown up 
to two consecutive times. After 
this, no recognition 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. In that 
case, follow the  following correc-
tion procedures to wash the vehi-
cle:
• Place the electronic key in a loca- tion 6 ft. (2 m) or more away from 
the vehicle. (Take care to ensure 
that the key is not stolen.)
• Set the electronic key to bat-

WARNING
■Caution regarding interfer-
ence with electronic devices
●People with implantable car-
diac pacemakers, cardiac 
resynchronization ther-
apy-pacemakers or implantable 
cardioverter defibrillators should 
keep away from the smart key 
system antennas. ( P.146) 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 ther-
apy-pacemakers or implantable 
cardioverter defib rillators should 
consult the manufacturer of the 
device for information about its 
operation under the influence of 
radio waves. Radio waves could 
have unexpected e ffects on the 
operation of such medical 
devices.
Ask your Toyota dealer for details 
on disabling the entry function.
