For safety drive
Adjust the angle of the seatback

and so that you do not have to
lean forward to steer. ( P. 150)
Adjust the seat so that you can
depress the pedals fully and so
that your arms bend slightly at the
elbow when gripping the steering
wheel. ( P. 150)
Lock the head restraint in place
with the center of the head
restraint closest to the top of your
ears. ( P. 1 5 8 )
Wear the seat belt correctly.
( P. 32)
Make sure that all occupants are we aring their seat belts before driving
the vehicle. ( P. 32)
Use a child restraint system appropriate for the child until the child
becomes large enough to properly wear the vehicle’s seat belt. ( P. 5 7 )
For safe driving, adjust the seat and mirror to an appropriate position

341-1. For safe use
GS450h_OM_OM30F70U_(U)The pretensioner helps the seat belt
to quickly restrain the occupant by
retracting the seat belt when the
vehicle is subjected to certain types
of severe frontal collision.
The front seat pretensioners also acti-
vate when the vehicle is subjected to
certain types of severe side collision.
The pretensioner does not activate in
the event of a minor frontal impact, a
minor side impact, a rear impact or a
vehicle rollover.
If the pre-collision sensor detects that
a collision is unavoidable, the pre-
collision system will retract the seat belt before the collision occurs.
( P. 290)
■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 comp letely 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. 6 1 )

■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. 5 7 )
●When the child becomes large enough to properly wear the vehicle’s seat belt, fol-
low the instructions regarding seat belt usage. ( P. 3 2 )
■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
If your seat belts cann ot 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
Observe the following precautions to reduce the risk of injury in the event of sudden
braking, sudden swerving or an accident.
Failure to do so may cause death or serious 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 pe rson 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.

CAUTION
■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 is no obvious damage.
●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 may lead to incorrect operation.
■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 chil d 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 seatin g 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.

CAUTION
■SRS airbag precautions
●The SRS front passenger airbag also deploys with considerable force, and can
cause death or serious injury especially if the front passenger is very close to the
airbag. The front passenger seat should be as far from the airbag as possible with
the seatback adjusted, so the front passenger sits upright.
●Improperly seated and/or restrained infa nts and children can be killed or seri-
ously injured by a deploying airbag. An in fant or child who is too small to use a
seat belt should be properly secured using a child restraint system. Lexus strongly
recommends that all infants and children be placed in the rear seats of the vehicle
and properly restrained. The rear seats ar e safer for infants and children than the
front passenger seat. ( P. 5 7 )
●If the seat belt extender has been con-
nected to the front seat belt buckle but the
seat belt extender has not also been fas-
tened to the latch plate of the seat belt, the
SRS front airbags will judge that the driver
and front passenger are wearing the seat
belt even though the seat belt has not been
connected. In this case, the SRS front air-
bags may not activate correctly in a colli-
sion, resulting in deat h or serious injury in
the event of a collision. Be sure to wear the
seat belt with the seat belt extender.
●Do not sit on the edge of the seat or lean
against the dashboard.
