Operation of each component
■Note for the entry function
●Even when the electronic key is within the effective range (detection areas), the
system may not operate properly in the following cases:
• The electronic key is too close to the window 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 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
“START STOP ENGINE” <“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 condi-
tions, 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 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 possible to start the
engine if the electronic key is near the window.
●The doors may unlock or lock if a large am ount of water splashes on the door han-
dle, such as in the rain or in a car wash when the electronic key is within the effec-
tive range. (The doors 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.)

Operation of each component
■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-button start can be deactivated in advance.
(→ P. 8 6 2 )
■Alarm
Using the smart access system with push-button start to lock the doors will set the
alarm system. ( →P. 8 6 )
■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 outside
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.)
●Do not leave the electronic key inside the luggage compartment.
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 luggage compartment),
conditions (inside a metal bag, close to metallic objects) and the radio waves in the
surrounding area. ( →P. 1 4 9 )
■If the smart access system with push-button start does not operate properly

■Electronic key battery depletion
●The standard battery life is 1 to 2 years.
●If the battery becomes low, an alarm will sound in the cabin when the engine
stops. (→P. 7 8 9 )
●As the electronic key always receives radio waves, the battery will become
depleted even if the electronic key is not used. The following symptoms indicate
that the electronic key battery may be depleted. Replace the battery when neces-
sary. ( →P. 7 1 9 )
• The smart access system with push-button start or the wireless remote control does not operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.
●To avoid serious deterioration, do not leave the electronic key within 3 ft. (1 m) of
the following electrical appliances that produce a magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cordless phones
• Table lamps
• Induction cookers
■When the electronic key battery is fully depleted
→ P. 7 1 9
■Customization
Settings (e. g. smart access system with push-button start) can be changed.
(Customizable features: → P. 8 6 2 )
■If the smart access system with push-button start has been deactivated in a cus-
tomized setting

CAUTION
■Trunk easy closer (vehicles with power trunk opener and closer)
■Power trunk opener and closer (if equipped)
Observe the following precautions when operating the power trunk opener and
closer.
Failure to do so may cause serious injury.
●Check the safety of the surrounding area to make sure there are no obstacles or
anything that could cause any of your belongings to get caught.
●If anyone is in the vicinity, make sure they are safe and let them know that the
trunk is about to open or close.
●If the trunk closer switch is pressed while the trunk lid is opening during automatic
operation, the trunk lid stops opening. Take extra care when on an incline, as the
trunk lid may open or close suddenly.
●On an incline, the trunk lid may fall after it opens automatically. Make sure the
trunk lid is fully open and secure before using the trunk.
●In the following situations, the power trunk opener and closer may detect an
abnormality and automatic operation may be stopped. In this case, the trunk lid
has to be operated manually. Take extra care in this situation, as the stopped trunk
lid may suddenly fall, causing an accident.
• When the trunk lid contacts an obstacle
• When the 12-volt battery voltage suddenly drops, such as when the “START STOP ENGINE” <“POWER”> switch is turned to IGNITION ON
mode or the engine is started during automatic operation
●Do not attach any accessories other than genuine Lexus parts to the trunk lid. The
power trunk opener and closer may not operate, causing itself to malfunction, or
the trunk lid may fall closed again after it is opened.
In the event that the trunk lid is left slightly
open, the trunk easy closer will automatically
close it to the fully closed position. It takes
several seconds before the trunk easy closer
begins to operate. Be careful not to catch fin-
gers or anything else in the trunk lid, as this
may cause bone fractures or other serious
injuries.
