■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, and
you can move around fully. Also, when retracting, if the belt is locked, pulling once
on the belt strongly will loosen the belt and allow you to move, and the belt can then
be pulled out.
■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. 114)
■Pregnant women
■People suffering illness
Obtain medical advice and wear the seat belt in the proper way. (P. 6 3 )
■Child seat belt usage
The seat belts of your vehicle were principally designed for persons of adult size.
●Use a child restraint system appropriately for the child, until the child becomes
large enough to properly wear the vehicle’s seat belt. (P. 1 1 0 )
●When the child becomes large enough to properly wear the vehicle’s seat belt,
follow the instructions on P. 63 regarding seat belt usage.
Obtain medical advice and wear the seat belt
in the proper way. (P. 6 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 a
pregnant woman, but also the fetus could suf-
fer death or serious injury as a result of sud-
den braking, sudden swerving or a collision.

CAUTION
■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. 6 4 )
■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.
■Child restraint lock function belt precaution
Do not allow children to play with the child 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 injury.
●Ensure that the belt and tab 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 a seat belt.
Have any necessary repairs carried out by your Lexus dealer. Inappropriate han-
dling of the pretensioner may cause it to activate or operate improperly and may
cause death or serious injury.
