■Preventing unintentional operation of
the Hands Free Power Back Door
When an electronic ke y is in the operation
range, the Hands Free Power Back Door
may operate unintentiona lly, so be careful in
the following situations.
●When a large amount of water is applied
to the rear bumper, such as when the
vehicle is being washed or in heavy rain
●When dirt is wiped off the rear bumper
●When a small animal or small object, such
as a ball, moves under the rear bumper
●When an object is moved from under the
rear bumper
●If someone is swinging their legs while sit-
ting on the rear bumper
●If the legs or another part of someone’s
body contacts the rear bumper while
passing by the vehicle
●When the vehicle is parked near an elec-
trical noise source which affects the sen-
sitivity of the Hands Free Power Back
Door, such as a pay parking spot, gas sta-
tion, electrically heated road, or fluores-
cent light
●When the vehicle is near a TV tower,
electric power plant, radio station, large
display, airport or other facility that gen-
erates strong radio waves or electrical
noise
●When the vehicle is parked in a place
where objects such as plants are near the
rear bumper
●If luggage, etc. is set near the rear
bumper
●If accessories or a vehicle cover is
installed/removed near the rear bumper
●When the vehicle is being towed
To prevent unintentional operation, turn the
Hands Free Power Back Door operation
setting off.
■When reconnecting the 12-volt battery
To enable the power back door to operate
properly, close the back door manually.
■Jam protection function
Sensors are installed in the right and left sides of the power back door. When the
door is automatically closing and the sen-
sors are pushed due to an object being
clamped, etc., the jam protection function
operates.
From that position the door automatically
moves a little in the opposite direction and
then the function stops.
■If the back door opener is inoperative
The back door can be unlocked from the
inside.
1 Remove the cover.
To protect the cover, place a rag between
the flathead screwdri ver and the cover as
shown in the illustration.

tomizable features: P.438)

1253-2. Opening, closing and locking the doors
3
Before driving■If “Key Detected in Vehicle” is shown on
the multi-information display
An attempt was made to lock the doors
using the smart access system with push-
button start while the electronic key was still
inside the vehicle. Retrieve the electronic
key from the vehicle and lock the doors
again.
■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
electronic 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 be used. To cancel
the function, press any of the electronic key
buttons.
●Electronic keys that will not be used for
long periods of time can be set to the bat-
tery-saving mode in advance.
■Conditions affecting 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 immobilizer system from oper-
ating properly. (Ways of coping: P.403)
●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

■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 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. 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 po ssible to start the
hybrid system if the el ectronic 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 doors wi ll 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.125)
●If the electronic key is inside the vehicle
and a door handle becomes wet during a
car wash, a buzzer may sound outside the
vehicle and “Key Detected in Vehicle”
may be shown on the multi-information
display. To turn off the alarm, lock all the
doors.

●The run-flat tires are for only this vehicle.
Do not use the tires on other vehicles.
●Do not mix run-flat tires and normal tires.
●If non-genuine Lexus wheels are used, it
may be impossible to sufficiently demon-
strate the performance of run-flat tires.
Your vehicle is equipped with a tire
pressure warning system that uses tire
pressure warning valves and transmit-
ters to detect low tire inflation pressure
before serious problems arise.
If the tire pressure drops below a
predetermined level, the driver is
warned by a screen display and a
warning light. ( P.387, 395)
 The tire pressure detected by the
tire pressure warning system can be
displayed on the multi-information
display. ( P.87)
The illustration used is intended as an
example, and may differ from the image
that is actually displayed on the multi-infor-
mation display.

The tire pressure warning system does not
replace routine tire inflation pressure
checks. Make sure to check tire inflation pressure as part of your routine of daily
vehicle checks.
■Tire inflation pressure
●It may take a few minutes to display the
tire inflation pressu
re after the power
switch is turned to ON. It may also take a
few minutes to display the tire inflation
pressure after inflatio n pressure has been
adjusted.
●Tire inflation pressure changes with tem-
perature. The displaye d values may also
be different from the values measured
using a tire pressure gauge.
