Linking driving position memory with door unlock operation
Record your driving position to button 1, 2 or 3 before performing the fol-
lowing:
Carry only the key (including the card key) to which you want to link the
driving position. If 2 or more keys are in the vehicle, the driving position
cannot be linked properly.
Shift the shift position to P and close the driver’s door. Turn the
“POWER” switch to ON mode. Press the desired button (1, 2 or 3)
to recall the position. Then, while
keep pressing the button, press the
driver’s door lock switches (either
lock or unlock) until the signal
beeps.
The driving position is recalled
when the driver’s door is unlocked
using the entry function or wireless
remote control and the driver ’s
door is opened.

■Operating the driving position memory after turning the “POWER” switch off
Memorized positions (except for the steering wheel position) can be activated up
to 180 seconds after the driver’s door is opened and another 60 seconds after it is
closed again, even after turning the “POWER” switch off.
■Canceling the linked door unlock operation
Turn the “POWER” switch to ON mode and close the driver’s door.
While pressing the “SET” button, press the driver’s door lock switches
(either lock or unlock) until the signal beeps.
■Stopping seat position operation part-way through
Perform any of the following operations:
●Press the “SET” button.
●Press button 1, 2 or 3.
●Adjust the seat using the switches (only cancels seat position recall).
●Adjust the steering wheel using the tilt and telescopic steering control switch
(only cancels steering wheel position recall).
■Correct seat position
When the seat is in the most forward or most backward position, and the seat is
being moved in those directions, the system may not correctly recognize the cur-
rent position and the memorized position will not be correctly recalled.
■Customization
If a seat position is memorized, the driver seat will move back the set distance
(→ P. 574) from that memorized position.
CAUTION
■Seat adjustment caution
Take care during seat adjustment so that the seat does not strike the rear passenger
or squeeze your body against the steering wheel.

Seat belts
Make sure that all occupants are wearing their seat belts before driving the
vehicle.
■Correct use of the seat belts
●Extend the shoulder belt so
that it comes fully over the
shoulder, but does not come
into contact with the neck or
slide off the shoulder.
● Position the lap belt as low as
possible over the hips.
● Adjust the position of the
seatback. Sit up straight and
well back in the seat.
● Do not twist the seat belt.
■ Fastening and releasing the seat belt

Seat belt pretensioners (front and outside rear seats)
The pretensioner helps the seat
belt to quickly restrain the occu-
pant by retracting the seat belt
when the vehicle is subjected to
certain types of severe frontal colli-
sion.
The pretensioner may not activate
in the event of a minor frontal
impact, a side impact or a rear
impact.
Pre-collision seat belts (front seats of vehicles with pre-collision system)
If the pre-collision sensor detects that a collision is unavoidable, the pre-
collision system will retract the seat belt, contributing to improvement of
the passenger’s protection.
The same will happen if the driver makes an emergency braking or loses con-
trol of the vehicle. ( →P. 232)
■Adjusting the seat belt shoulder anchor height (front seats)
Push the seat belt shoulder
anchor down while pressing
the release button.
Push the seat belt shoulder
anchor up.
Move the height adjuster up and
down as needed until you hear a
click.

■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 too quickly. A slow, easy motion will allow the belt to extend so that
you can move around fully.
■Automatic locking retractor (ALR)
When a passenger’s shoulder belt is completely extended and then retracted even
slightly, the belt is locked in that position and cannot be extended. This feature is
used to hold the child restraint system (CRS) firmly. To free the belt again, fully
retract the belt and then pull the belt out once more. ( →P. 1 2 5 )
■Pregnant women
■People suffering illness
Obtain medical advice and wear the seat belt in the proper way. ( →P. 7 3 )
■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 2 1 )
●When the child becomes large enough to properly wear the vehicle’s seat belt,
follow the instructions on P. 73 regarding seat belt usage. Obtain medical advice and wear the seat belt
in the proper way. (
→P. 7 3 )
Women who are pregnant should position
the lap belt as low as possible over the hips in
the same manner as other occupants. Extend
the shoulder belt completely over the shoul-
der 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
the pregnant woman, but also the fetus could
suffer death or serious injury as a result of
sudden braking or a collision.

■Replacing the belt after the pretensioner has been activated
If the vehicle is involved in multiple collisions, the pretensioner will activate for the
first collision, but will not activate for the second or subsequent collisions.
■Seat belt extender
CAUTION
■Wearing a seat belt
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 serious injury.
●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.
●To achieve a proper seating position, do not recline the seat more than necessary.
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.
If your seat belts cannot be fastened securely
because they are not long enough, a person-
alized seat belt extender is available from
your Lexus dealer free of charge.

CAUTION
■Seat belt pretensioners
●Do not place anything, such as a cushion, on the front passenger’s seat. Doing so
will disperse the passenger’s weight, which prevents the sensor from detecting
the passenger’s weight properly. As a result, the seat belt pretensioner for the
front passenger’s seat may not activate in the event of a collision.
●If the pretensioner has activated, the SRS warning light will come on. In that case,
the seat belt cannot be used again and must be replaced at your Lexus dealer.
■Adjustable shoulder anchor
Always make sure the shoulder belt is positioned across the center of your shoul-
der. The belt should be kept away from your neck, but not falling off your shoulder.
Failure to do so could reduce the amount of protection in an accident and cause
death or serious injuries in the event of a sudden stop, sudden swerve or accident.
(→ P. 74 )
■Child restraint lock function belt precaution
Do not allow children to play with the chil d restraint lock function belt. If the belt
becomes twisted around a child’s neck, it will not be possible to pull the belt out
leading to choking or other serious injuries that could result in death.
If this occurs and the buckle cannot be unfastened, scissors should be used to cut
the belt.
■Seat belt damage and wear
●Do not damage the seat belts by allowing the belt, plate, or buckle to be jammed
in the door.
●Inspect the seat belt system periodically. Check for cuts, fraying, and loose parts.
Do not use a damaged seat belt until it is replaced. Damaged seat belts cannot
protect an occupant from death or serious injury.
●Ensure that the belt and plate are locked and the belt is not twisted.
If the seat belt does not function correctly, immediately contact your Lexus
dealer.
●Replace the seat assembly, including the belts, if your vehicle has been involved in
a serious accident, even if there’s no obvious damage.

CAUTION
●Do not attempt to install, remove, modify, disassemble or dispose of the seat belts.
Have any necessary repairs carried out by your Lexus dealer. Inappropriate han-
dling of the pretensioner may prevent it from operating properly, resulting in
death or serious injury.
■Using a seat belt extender
●Do not wear the seat belt extender if you can fasten the seat belt without the
extender.
●Do not use the seat belt extender when installing a child restraint system because
the belt will not securely hold the child restraint system, increasing the risk of
death or serious injury in the event of an accident.
●The personalized extender may not be safe on another vehicle, when used by
another person, or at a different seating position other than the one originally
intended.
NOTICE
■When using a seat belt extender
When releasing the seat belt, press on the buckle release button on the extender,
not on the seat belt.
This helps prevent damage to the vehicle interior and the extender itself.
