1203-2. Opening, closing and locking the doors and trunk
■Note for the entry function
●Even when the electronic key is within the 
effective range (detection areas), the sys-
tem may not operate properly in the fol-
lowing cases:
• The electronic key is too close to the win- dow or outside door handle, 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 rear 
bumper center when the trunk is opened.
• The electronic key is on the instrument  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 
conditions, it may be  detected by the 
antenna outside the cabin and the doors 
will become lockable from the outside, 
possibly trapping the electronic key 
inside the vehicle.
●As long as the electron ic 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 possible to start the 
engine  if the electronic 
key is near the window.
●The doors may unlock or lock if a large 
amount of water spla shes 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 auto-
matically be locked after approximately 
60 seconds if the d oors 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.)
●When the lock operation is performed  using the lock sensor, recognition 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 this case, follow the follow-
ing correction procedures to wash the 
vehicle:
• Place the electronic key in a location 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 access system 
with push-button start. ( P.119)
●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 vehicle. To 
turn off the alarm, lock both side doors.
●If an outside door handle is not retracted 
during a car wash, a door may be opened 
or an outside door handle may be dam-
aged. Make sure that  the outside door 
handles are retracted before using the 
car wash.
●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.
●Unlocking the vehicle may take more 
time if another electronic key is within the 
effective range.
■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 access system with push-but-
ton start can be deactivated in advance.
●Setting the electronic key to battery-sav-
ing mode helps to reduce key battery 
depletion. ( P.119)

WARNING
■Caution regarding interference with 
electronic devices
●People with implantable cardiac pace-
makers, cardiac resynchronization 
therapy-pacemakers or implantable 
cardioverter defibrillators should keep 
away from the smart access system 
with push-button start antennas. 
( P.117)
The radio waves may affect the opera-
tion of such devices. If necessary, the 
entry function can be disabled. Ask 
your Lexus dealer for details, such as 
the frequency of radio waves and tim-
ing of the emitted radio waves. Then, 
consult your doctor to see if you 
should disable the entry function.
●Users of any electrical medical device 
other than implantable cardiac pace-
makers, cardiac resynchronization 
therapy-pacemakers or implantable 
cardioverter defibrillators should con-
sult the manufacturer of the device for 
information about its operation under 
the influence of radio waves.
Radio waves could have unexpected 
effects on the operation of such medi-
cal devices.
Ask your Lexus dealer for details on dis-
abling the entry function.
