Before driving
■When “Smart Access System Malfunc-
tion See Owner’s Manual” will be dis-
played on the multi-information display
The system may be malfunctioning. Have 
the vehicle inspected by your Lexus dealer 
immediately.
■Battery-saving function
The battery-saving fu nction will be acti-
vated in order to prevent the electronic key 
battery and the 12-volt battery from being 
discharged while the vehicle is not in opera-
tion for a long time.
●In the following situations, the smart 
access system with pu sh-button start may 
take some time to unlock the doors.
• The electronic key has been left in an  area of approximately  6 ft. (2 m) of the 
outside of the vehicle for 10 minutes or 
longer.
• The smart access system with push-but- ton start has not been used for 5 days or 
longer.
●If the smart access system with push-but-
ton start has not been  used for 14 days or 
longer, the doors cannot be unlocked at 
any doors except the driver’s door. In this 
case, take hold of the driver’s door han-
dle, 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 elec- tronic key from receiving radio waves.
Press   twice while pressing and 
holding .

buttons.
■Conditions affecting operation
The smart access system with push-button 
start, wireless remote control and immobi-
lizer system use weak  radio waves. In the 
following situations, the communication 
between the electronic key and the vehicle 
may be affected, preventing the smart 
access system with push-button start, wire-
less remote control and immobilizer system 
from operating properly. (Ways of coping: 
 P.389)
●When the electronic key battery is 
depleted
●Near a TV tower, electric power plant, 
gas station, radio stat ion, large display, 
airport or other fac ility 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

■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.

in a high place, or too close to the rear 
bumper center when the back door is 
opened.

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 door 
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.
●Even if the electronic  key is not inside the 
vehicle, it may be possible to start the 
hybrid 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 door will automatically 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 
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 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.121)
●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 all 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 approach to the effective 
range or door handle may prevent 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

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.120)
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.
