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 effec-
tiveness of the seat be lt and head restraint.●
Do not place anything under the front seats.
Objects placed under the front seats may be come jammed in the seat tracks and stop
the seat from locking in place. This may lead to an accident and the adjustment mech-
anism 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 drivin g, do not force yourself to continue driving
and take a break immediately.

quickly restrain the occupants by
retracting the seat belts when the vehi-
cle is subjected to certain types of
severe frontal or side collision or a vehi-
cle rollover. The pretensioners do not activate in the
event of a minor frontal impact, a minor
side impact or a rear impact.Adjusting the seat belt shoulder anchor height (front seats)

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 w ill allow the belt to ex tend 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 an d 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 princi pally designed for persons of adult size. ●
Use a child restraint system appropriate fo r the child, until the child becomes large
enough to properly wear the vehicle’s seat belt. (  P. 5 9 )●
When the child becomes large enough to prop erly wear the vehicle’s seat belt, follow
the instructions regardin g seat belt usage. (  P. 3 2 )■
Replacing the belt after the pretensioner has been activated
If the vehicle is involved in multiple collisio ns, the pretensioner will activate for the first
collision, but will not activate for th e second or subsequent collisions.■
Seat belt extender
If your seat belts canno t be fastened securely
because they are not long enough, a personal-
ized seat belt extender is available from your
Lexus dealer free of charge.

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 caus e death or serious injury.■
Wearing a seat belt ●
Ensure that all passen gers 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 occupa nts 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. ■
Pregnant women
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 possib le 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.

 P. 7 0 ■
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 pas-
senger’s weight properly. As a result, the seat belt pretensioner for the front passen-
ger’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 shoulder.
The belt should be kept away from your ne ck, 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 )■
Seat belt damage and wear ●
Do not damage the seat belts by allowing th e 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. ●
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 handling
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 in stalling 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.

RX450h_U_OM0E013U Your vehicle is equipped with ADVANCED AIRBAGS designed based on the
US motor vehicle safety standards (FMVSS208). The airbag sensor assembly
(ECU) controls airbag deployment based on information obtained from the sen-
sors etc. shown in the system compon ents diagram above. This information
includes crash severity and occupant information. As the airbags deploy, a
chemical reaction in the inflators quickly fills the airbags with non-toxic gas to
help restrain the moti on of the occupants.SRS airbag system components
