1183-2. Opening, closing and locking the doors and trunk
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.
ODo 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.
OAs 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.
OEven 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.
OThe 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.)
OIf 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.)
OTouching the door lock sensor while
wearing gloves may delay or prevent
lock operation. Remove the gloves and
touch the lock sensor again.
OWhen 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.
OUnlocking the vehicle may take more
time if another electronic key is within the
effective range.
OIf 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)
OIf 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.
OThe 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.
OA 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.
QWhen the vehicle is not driven for
extended periods
OTo prevent theft of the vehicle, do not
leave the electronic key within 6 ft. (2 m)
of the vehicle.
OThe smart access system with push-but-
ton start can be deactivated in advance.
OBattery-saving mode can reduce the
power consumption of electronic keys.

QTo operate the system properly
OMake 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 electronic 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.)
ODo not leave the electronic key inside the
trunk.
The key confinement prevention function
may not operate, depending on the loca-
tion of the key (close to a spare tire, the
inside edge of the trunk), conditions
(inside a metal bag, close to metallic
objects) and the radio waves in the sur-
rounding area. (P.112)
QIf an electronic key does not work prop-
erly

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.
OUsers 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.
