be set to the battery-saving mode  
in advance.

The battery-saving function will be  
activated in order to prevent the  
electronic key battery and the vehi-  
cle battery from being discharged  
while the vehicle is not operated for  
a long time.  
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 engine immobilizer sys-  
tem from operating properly.  
In the following situations, the  
smart key system may take some  
time to unlock the doors.  
• The electronic key has been left  
within approximately 11 ft. (3.5 m)  
of the outside of the vehicle for 2  
minutes or longer.  
When the electronic key battery is  
depleted  
• The smart key system has not

If the doors cannot be  
locked/unlocked using the above  
methods, use the mechanical key.  
(P.382)  
When carrying a portable radio,

other wireless communication  
device  
If the engine cannot be started using  
the smart key system, refer to  
P.382.  
Note for the entry function  
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  
• Media such as CDs and DVDs  
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.  
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  
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.  
• 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  
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.  
When the vehicle is parked in a  
pay parking spot where radio  
waves are emitted  
If the doors cannot be  
locked/unlocked using the smart key  
system, lock/unlock the doors by  
performing any of the following:  
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.  
Bring the electronic key close to  
either front door handle and oper-  
ate the entry function.

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 possibility that the door  
may not be unlocked by the entry  
function. (Use the wireless remote  
control to unlock 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.  
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.  
If the doors have been locked  
from outside of the vehicle and are  
then not unlocked using the wire-  
less remote control or smart key  
system, the engine cannot be  
started using the smart key sys-  
tem. (However, if the doors have  
been locked from inside the vehi-  
cle, the engine can be started  
using the smart key system.)  
If it is necessary to start the  
engine, it can be started using the  
procedure in “If the electronic key  
dose not operate properly”

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  
(P.382).  
To prevent theft of the vehicle, do  
not leave the electronic key within  
6 ft. (2 m) of the vehicle.  
Touching the door lock or unlock  
sensor while wearing gloves may  
prevent lock or unlock operation.  
The smart key system can be  
deactivated in advance. (P.412)  
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.  
Setting the electronic key to bat-  
tery-saving mode helps to reduce  
key battery depletion. (P.121)  
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.  
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.)  
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.)  
• Set the electronic key to bat-  
smart key system. (P.121)

Do not leave the electronic key  
inside the trunk.  
Users of any electrical medical  
device other than implantable  
cardiac pacemakers, cardiac  
resynchronization ther-  
apy-pacemakers or implantable  
cardioverter defibrillators should  
consult the manufacturer of the  
device for information about its  
operation under the influence of  
radio waves.  
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.  
(P.119)  
Radio waves could have unex-  
pected effects on the operation  
of such medical devices.

WARNING  
Caution regarding interfer-  
ence with electronic devices  
People with implantable car-  
diac pacemakers, cardiac  
resynchronization ther-  
apy-pacemakers or implantable  
cardioverter defibrillators should

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.
