■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 within
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
the passenger door. In this case, push the
depression on the front edge the driver’s
door handle, or use the wireless remote
control or 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 re ceiving radio waves.
Press twice while pressing and
holding . Confirm that the elec-
tronic key indicator flashes 4 times.
While the battery-saving mode is set, the
smart access system with push-button start
cannot be used. To cancel the function,
press any of the electronic key buttons.
■Conditions affe cting operation
The smart access system with push-button
start uses weak radio waves. In the following
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 engine immobilizer system
from operating prop-
erly.
(Ways of coping: P.359)
●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 carrying a portable radio, cellular
phone, cordless phone or other wireless
communication device
●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 keys (that emit radio
waves) are being used nearby
●When carrying the electronic key
together with the following devices that
emit radio waves
• Another vehicle’s electronic key 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
■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.

1183-2. Opening, closing and locking the doors and trunk
• 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.117)
●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.
■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 vehicle.
Depending on the position and holding
condition of the elec tronic key, the key
may not be detected correctly and the
system may not operate properly. (The
alarm may go off accidentally, or the door
lock prevention function may not oper-
ate.)

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.115)
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.
