1013-2. Opening, closing and locking the doors and trunk
3
Before driving
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.)
●Touching the door lock or unlock sensor
while wearing gloves may prevent lock or
unlock operation.
●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.100)
●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.
●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 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 electr onic 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 pre-
vention function may not operate.)
●Do not leave the electr onic 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 [if
equipped], the inside edge of the trunk),
conditions (inside a metal bag, close to
metallic objects) an d the radio waves in
the surrounding area. ( P.98)
■If the smart access system with
push-button start does not operate
properly
●Locking and unloc king the doors and
opening the trunk: P.332
●Starting the engine:  P.333
■Customization
Some functions can be customized.

in a customized setting
●Locking and unlocking the doors and
opening the trunk:
Use the wireless remote control or
mechanical key. (P.92, 96, 332)
●Starting the engine and changing engine
switch modes: P.333
●Stopping the engine: P.129
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.99)
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.

WARNING
■When adjusting the seat position
●Take care when ad justing the seat

●Do not put your hands under the seat
or near the moving parts to avoid
injury.

around the feet so they do not get
stuck.
■Seat adjustment
To reduce the risk of sliding under the lap
belt during a collision, do not recline the
seat more than necessary.
If the seat is too reclined, the lap belt may
slide past the hips and apply restraint
forces directly to the abdomen, or your
neck may contact the shoulder belt,
increasing the risk of death or serious
injury in the event of an accident.
Adjustments should not be made while
driving as the seat may unexpectedly
move and cause the driver to lose control
of the vehicle.

(  P.217)
■Auto anti-glare function (if equipped)
When the anti-glare insi de rear view mirror
is set to automatic mode, the outside rear
view mirrors will activate in conjunction with
the anti-glare inside rear view mirror to
reduce reflected light. ( P.109)
■Automatic adjustment of the mirror
angle (if equipped)
A desired mirror face angle can be entered
to memory and recalled automatically by
the driving position memory. ( P.105)
■Linked mirror function when reversing
(if equipped)
When either “L” or “R” of the mirror select
switch is selected, the outside rear view mir-
rors will automatically angle downwards
when the vehicle is reversing in order to
give a better view of the ground. To disable this function, select neither “L”
nor “R”.
To set the mirror angle used when the vehi-
cle is reversing, adjust the mirror angle at a
desired position with the shift lever in R.
The adjusted angle will be memorized and
the mirror will automatically tilt to the mem-
orized angle whenever the shift lever is
shifted to R from next time.
The memorized downward tilt position of
the mirror is linked to the normal position
(angle adjusted with th
e shift lever in other
than R). Therefore, if the normal position is
changed after adjustment, the tilt position
will also change.
When the normal position is changed, read-
just the angle in reversing.
Push the mirror back in the direction of
the vehicle’s rear.
