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 .
Confirm that the electronic key indicator
flashes 4 times. While the battery-saving
mode is set, the smart access system with
push-button start cannot

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,

■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 back door is
opened.
• The electronic key is on the instrument panel, luggage room, 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 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

(  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.
