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 may not
function.)
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 unlocked.
• The electronic key is on the instrument panel, rear package tray or
floor, or in the glove box when the engine is started or “ENGINE
START STOP” 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 electronic key is within the effective range, the doors may
be locked or unlocked by anyone.
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 if a large amount of water splashes on the door
handle, such as in the rain or in a car wash. (The doors will automatically
be locked after approximately 30 seconds if the doors are not opened and
closed.)
Gripping the door handle when wearing a glove may not unlock the
door.
If the wireless remote control is used to lock the doors when the elec-
tronic 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.)
A sudden approach to the effective range or door handle operation may
prevent the doors from being unlocked. In this case, return the door han-
dle to the original position and check that the doors unlock before pulling
the door handle again.

CAUTION
Caution regarding interference with electronic devices
People with implanted pacemakers or cardiac defibrillators should main-
tain a reasonable distance between themselves and the smart entry & start
system antennas. (P. 3 8 )
The radio waves may affect the operation of such devices. If necessary,
the entry function can be disabled. Ask any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional, for details,
such as the frequency of radio waves and timing of emitting the radio
waves. Then, consult your doctor to see if you should disable the entry
function.
User of any electrical medical device other than implanted pacemakers
and implanted cardiac defibrillators should consult 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 med-
ical devices.
Ask any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional, for details for disabling the entry function.

resulting in death or serious injury.
Always use a seat belt.
Ensure that all doors are properly closed.
Do not pull the inside handle of the doors while driving.
The doors may be opened and the passengers may be thrown out of the

Set the rear door child protector locks when children are seated in the rear
seat.

Seat belt pretensioners
The pretensioner helps the seat
belt to quickly restrain the
occupant by retracting the seat
belt when the vehicle is sub-
jected to certain types of severe
frontal collision.
The pretensioner may not acti-
vate in the event of a minor
frontal impact, a side impact or
a rear impact.
Pre-crash seat belts (front seats of vehicles with pre-crash safety sys-
tem)
If the pre-crash sensor detects that a collision is unavoidable, the
pre-crash safety system will retract the seat belt, thus enhancing
the effectiveness of the seat belt pretensioner in a crash.
The same will happen if the driver makes an emergency braking or
loses control of the vehicle. (P. 2 1 1 )
Emergency locking retractor (ELR)
The retractor will lock the belt during a sudden stop or on impact. It may
also lock if you lean forward or pull out the belt too quickly. Allow the belt
to fully retract, and then slowly extend the belt. If the belt cannot be pulled
out of the retractor, firmly pull the belt and release it. You will then be able
to smoothly pull the belt out of the retractor.

Pregnant women
People suffering illness
Obtain medical advice and wear the seat belt in the proper way.
Child seat belt usage
The seat belts of your vehicle were principally designed for persons of adult
size.
Use a child restraint system appropriate for the child, until the child
becomes large enough to properly wear the vehicle's seat belt. (P. 1 1 6 )
When the child becomes large enough to properly wear the vehicle's seat
belt, follow the instructions on P. 70 regarding seat belt usage.
Replacing the belt after the pretensioner has been activated
If the vehicle is involved in multiple collisions, the pretensioner will acti-
vate for the first collision, but will not activate for the second or subsequent
collisions.
Seat belt regulations
If seat belt regulations exist in the country where you reside, please contact
any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional, for seat belt replacement or installation.
Obtain medical advice and wear the seat
belt in the proper way. (P. 70)
Women who are pregnant should position
the lap belt as low as possible over the
hips in the same manner as other occu-
pants. Extend the shoulder belt com-
pletely over the shoulder and position the
belt across the chest. Avoid belt contact
over the rounding of the abdominal area.
If the seat belt is not worn properly, not
only a pregnant woman, but also the fetus
could suffer death or serious injury as a
result of sudden braking or a collision.

CAUTION
Observe the following precautions to reduce the risk of injury in the event of
sudden braking, sudden swerving or an accident.
Failing to do so may cause death or severe injury.
Wearing a seat belt
Ensure that all passengers wear a seat belt.
Always wear a seat belt properly.
Each seat belt should be used by one person only. Do not use a seat belt
for more than one person at once, including children.
Lexus recommends that children be seated in the rear seat and always use
a seat belt and/or an appropriate child restraint system.
Do not recline the seat any more than necessary to achieve a proper seat-
ing position. The seat belt is most effective when the occupants are sitting
up straight and well back in the seats.
Do not wear the shoulder belt under your arm.
Always wear your seat belt low and snug across your hips.
When children are in the vehicle
Do not allow children to play with the seat belt. If the seat belt becomes
twisted around a child’s neck, it may lead to choking or other serious inju-
ries that could result in death.
If this occurs and the buckle cannot be unfastened, scissors should be used
to cut the belt.
