■Seat adjustment
●Do not recline the seat more than necessary when the vehicle is in motion to
reduce the risk of sliding under the lap belt.
If the seat is too reclined, the lap belt may slide past the hips and apply restraint
forces directly to the abdomen or your neck may contact the shoulder belt,
increasing the risk of death or serious injury in the event of an accident.
●Manual seat only: After adjusting the seat , make sure that the seat is locked in
position.

Seat belt comfort guide (outside rear seats)
If the shoulder belt sits close to a
person’s neck, slide the seat belt
comfort guide forward.
Seat belt pretensioners (front and outside rear seats)The pretensioner helps the seat
belt to quickly restrain the occu-
pant by retracting the seat belt
when the vehicle is subjected to
certain types of severe frontal colli-
sion.
The pretensioner may not activate
in the event of a minor frontal
impact, a side impact or a rear
impact.
■ Adjusting the height of the belt (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 or pull out the belt too quickly. Allow the belt to fully retract, and
then slowly extend the belt. If the belt cannot be pulled out of the retractor, firmly
pull the belt and release it. You will then be able to smoothly pull the belt out of the
retractor.
■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. 118)
■Pregnant women
Obtain medical advice and wear the seat belt
in the proper way. ( P. 6 5 )
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 or a collision.

■People suffering illness
Obtain medical advice and wear the seat belt in the proper way.
■Child seat belt usage
The seat belts of your vehicle are 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. 114)
●When the child becomes large enough to properly wear the vehicle's seat belt,
follow the instructions on P. 65 regarding seat belt usage.
■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.
Failing to do so may cause death or severe 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.
●Do not recline the seat any more than necessary to achieve a proper seating
position. 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.
■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 un fastened, scissors should be used to cut
the belt.
■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 yo ur 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.

CAUTION
■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, wh ich prevents the sensor from detecting
the passenger’s weight properly. As a resu lt, 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.
■Seat belt damage and wear
Inappropriate handling of th e pretensioner may prevent it from operating properly
resulting in death or serious injury.
●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 tab are lo cked and the belt is not twisted.
If the seat belt does not function co rrectly, immediately contact your Lexus
dealer.
●Replace the seat assembly, including the belt s, 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.
■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.

■Using a seat belt comfort guide
Failure to observe the following precautions could reduce the effectiveness of the
seat belt in an accident, causing death or serious injury.
Always make sure the shoulder belt is positioned across the center of the shoulder.
The belt should be kept away from the neck, and should not fall off the shoulder.
NOTICE
■When using a seat belt extender
