once for 5 seconds
●When an interior alarm pings con-
tinuously
■Battery-saving function
The battery-saving function will be 
activated in order to prevent 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 11.5 ft. 
(3.5 m) of the outside of the vehi-
cle for 2 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 canno t be unlocked at 
any 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.
■Turning an electronic key to 
battery-saving mode
●When battery-saving mode is set, 
battery depletion is minimized by 
stopping the electronic key from 
receiving radio waves.
Press   twice while pressing 
and holding  .
Confirm that the ele ctronic key indi-
cator flashes 4 times. 
While the battery-saving mode is 
set, the smart key system cannot be 
used. To cancel the function, press 
any of the electronic key buttons.
●Electronic keys that will not be 
used for long periods of time can 
be set to the battery-saving mode 
in advance.
■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.
●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 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 on the instru- ment panel, luggage cover or 
floor, or in the door pockets or 
glove box when the EV 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 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 lo ck or unlock the 
vehicle.
●Even if the electro nic key is not 
inside the vehicle, it may be possi-
ble to start the EV system if the 
electronic key is near the window.
●The doors may unlock 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 effective range. 
(The doors will au tomatically be 
locked after approximately 60 sec-
onds 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 sensor 
while wearing gloves may delay or 
prevent lock operation. Remove 
the gloves and touch the lock sen-
sor again.
●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

Owners Manual_USA_M42C01_enlock and unlock repeatedly. In that 
case, follow the fo
llowing 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 battery-
saving mode to disable the smart 
key system. ( P.188)
●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-informatio n 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 com es into contact 
with ice, snow, mud, etc. Clean 
the lock sensor and attempt to 
operate it again.
●A sudden approach to the effec-
tive range or door handle may pre-
vent the doors from being 
unlocked. In this case, return the 
door handle to the original position 
and check that the doors unlock 
before pulling the door handle 
again.
●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.569)
●Battery-saving mode can reduce 
the power consumption of elec-
tronic keys. ( P.188)
■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 operating the 
system from the out
side of the vehi-
cle.
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 may not operate.)
■If the smart key  system does 
not operate properly
●If the doors cannot be locked or 
unlocked, perform the following.
• Bring the electronic key close to  the door handle and perform a 
lock or unlock operation.
• Use the wireless remote control.
If the doors cannot be locked or 
unlocked by perform the above, use 
the mechanical key. ( P.539)

used while the alarm system is set, 
the warning will sound. ( P. 6 9 )
●If the EV system cannot be 
started, refer to P.540
■Customization
Settings (e.g. smart key system) 
can be changed.
(Customizable features:  P.569)
If the smart key system has been 
deactivated in a customized setting, 
refer to the explanations for the fol-
lowing operations.

■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.187)
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.
●User 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 
for disabling the entry function.
