control and engine  immobilizer sys-
tem from operating properly.
●When the electronic key battery is 
depleted
●Near a TV tower, electric power 
plant, gas station, radio station, 
large display, airport 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 aluminum foil is  attached
• Cigarette boxes that have alumi-
num foil inside
• Metallic wallets or bags
•Coins
• Hand warmers made of metal

■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 when the trunk is opened.
• The electronic key is on the instru- ment panel, rear package tray or 
floor, or in the door pockets or 
glove box when the engine is 
started or engine 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 co nditions, 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 electronic key is not 
inside the vehicle, it may be possi-
ble to start the engine if the elec-
tronic 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 possibilit y 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- tery-saving mode to disable the 
smart key system. ( P.113)
●If the electronic key is inside the 
vehicle and a door handle 
becomes wet during a car wash, a 
message may be shown on the 
multi-information  display and a 
buzzer will sound outside the vehi-
cle. To turn off the alarm, lock all 
the doors.
●The lock sensor may not work 
properly if it co mes into contact 
with ice, snow, mud, etc. Clean 
the lock sensor and attempt to 
operate it again.
●A sudden handle operation or a 
handle operation immediately 
after entering the effective range 
may prevent the doors from being 
unlocked. Touch the door unlock 
sensor and check that the doors 
are unlocked before pulling the 
door handle again.

Before driving
●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 driven 
for extended periods
●To prevent theft of the vehicle, do 
not leave the electronic key within 
6 ft. (2 m) of the vehicle.
●The smart key system can be 
deactivated in advance. ( P.548)
●Setting the electronic key to bat-
tery-saving mode helps to reduce 
key battery depletion. ( P. 1 1 3 )
■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 operat-
ing the system from the outside of 
the vehicle.
Depending on the position and hold-
ing condition of the electronic key, 
the key may not be detected cor-
rectly and the system may not oper-
ate properly. (The alarm may go off 
accidentally, or the door lock pre-
vention function may not operate.)
●Do not leave the electronic key 
inside the trunk.
The key confinement prevention 
function may not operate, depend-
ing on the location of the key (the 
inside edge of the trunk), condi-
tions (inside a metal bag, close to 
metallic objects)  and the radio 
waves in the surrounding area.

diac pacemakers, cardiac 
resynchronization ther-
apy-pacemakers or implantable 
cardioverter defib rillators should 
keep away from the smart key 
system antennas. ( P. 1 1 1 )
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 defi brillators should 
consult the manufacturer of the 
device for information about its 
operation under the influence of 
radio waves.
