1043-2. Opening, closing and locking the doors and trunk
situations, the communication between the 
electronic key and the vehicle may be 
affected, preventing the smart access sys-
tem with push-button start, wireless remote 
control and immobilizer system from oper-
ating properly. 
(Ways of coping:  P.382)
●When the electronic key battery is 
depleted
●Near a TV tower, electric power plant, 
gas station, radio stat ion, large display, 
airport or other faci lity that generates 
strong radio waves or electrical noise
●When the electronic key is in contact 
with, or is covered by the following metal-
lic objects
• Cards to which aluminum foil is attached
• Cigarette boxes that  have aluminum foil 
inside
• Metallic wallets or bags
•Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
●When other wireless ke ys (that emit radio 
waves) are being used nearby
●When carrying the electronic key 
together with the following devices that 
emit radio waves
• Portable radio, cellular phone, cordless  phone or other wireless communication 
device
• Another electronic ke y or a wireless key 
that emits radio waves
• Personal computers or personal digital  assistants (PDAs)
• Digital audio players
• Portable game systems
●If window tint with a metallic content or 
metallic objects are attached to the rear 
window
●When the electronic key is placed near a 
battery charger or electronic devices
●When the vehicle is parked in a pay park-
ing spot where radio waves are emitted.
■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 center 
of the rear bumper 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 
hybrid 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 outside the cabin and the doors 
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 po ssible to start the 
hybrid system if the el ectronic 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 effective 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 possibility 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 sensor again.
●When the lock operation is performed 
using the lock sensor, recognition signals 
will be shown up to two consecutive

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.102)
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.
