that your arms bend slightly at the
elbow when gripping the steering
wheel. ( →P. 1 4 8 )

restraint closest to the top of your

Adjusting the mirrors
CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
●Do not adjust the position of the driver’s seat while driving.
Doing so could cause the driver to lose control of the vehicle.
●Do not place a cushion between the driver or passenger and the seatback.
A cushion may prevent correct posture from being achieved, and reduce the
effectiveness of the seat belt and head restraint.
●Do not place anything under the front seats.
Objects placed under the front seats may become jammed in the seat tracks and
stop the seat from locking in place. This may lead to an accident and the adjust-
ment mechanism may also be damaged.
●When driving over long distances, take regular breaks before you start to feel
tired.
Also, if you feel tired or sleepy while driving, do not force yourself to continue
driving and take a break immediately.

GS450h_U (OM30D01U)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. 2 9 6 )
■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. 5 9 )

■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 5 )
●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 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
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 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.

CAUTION
■Pregnant women
■People suffering illness
Obtain medical advice and wear the seat belt in the proper way. (→P. 3 2 )
■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 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 pretensioners
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. 3 3 )
Obtain medical advice and wear the seat
belt in the proper way. ( →P. 3 2 )
Women who are pregnant should position
the lap belt as low as possible over the hips in
the same manner as other occupants,
extending the shoulder belt completely over
the shoulder and avoiding belt contact with
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.

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 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.
