For safety and security
RX450h_RX450hL _U_OM48F85UThe pretensioners help the seat belts to
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. ■
Emergency locking retractor (ELR)
The retractor will lock th e 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 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. 57)■
Child seat belt usage
The seat belts of your vehicle were principally 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. 55)●
When the child becomes large enough to properly wear the vehicle’s seat belt, follow
the instructions regardin g seat belt usage. ( → P. 32)■
Replacing the belt after the pr etensioner has been activated
If the vehicle is involved in multiple collisions, the pretensioner will activate for the first
collision, but will not activate for th e second or subsequent collisions.■
Seat belt extenderSeat belt pretensioners (front seats and outboard second-row seats)
If your seat belts cannot be fastened securely
because they are not long enough, a personal-
ized seat belt extender is available from your
Lexus dealer free of charge.

RX450h_RX450hL _U_OM48F85UWARNING ■
People suffering illness
Obtain medical advice and wear the seat belt in the proper way. ( → P. 32)■
When children are in the vehicle
→ P. 66 ■
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 wa rning 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 posi tioned across the center of your shoulder.
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. 32)■
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 correct ly, immediately contact your Lexus dealer.●
Replace the seat assembly, incl uding the belts, if your vehi cle 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 inco rrect 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 restrain t system because the
belt will not securely hold the child restra int 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 releasing 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.

38 1-1. For safe use
RX450h_RX450hL _U_OM48F85UYour vehicle is equipped with ADVA NCED AIRBAGS designed based on the
US motor vehicle safety standards (F MVSS208). 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 motion of the occupants.SRS airbag system components
