WARNING
■General precautions while driving
Driving under the influence: Never drive your vehicle when under the influence of
alcohol or drugs that have impaired your ability to operate your vehicle. Alcohol and
certain drugs delay reaction time, impair judgment and reduce coordination, which
could lead to an accident that could result in death or serious injury.
Defensive driving: Always driv e defensively. Anticipate mistakes that other drivers or
pedestrians might make and be ready to avoid accidents.
Driver distraction: Always give your full attention to driving. Anything that distracts the
driver, such as adjusting controls, talking on a cellular phone or reading can result in a
collision with resulting death or serious in jury to you, your occupants or others.
■General precaution regarding children’s safety
Never leave children unattended in the vehicl e, and never allow children to have or use
the key.
Children may be able to start the vehicle or sh ift the vehicle into neutral. There is also a
danger that children may injure themselves by play ing with the windows, the moon
roof, or other features of the vehicle. In addition, heat build-up or extremely cold tem-
peratures inside the vehicle can be fatal to children.

For safety and security
For children or smaller-than-average
people, slide the seat belt comfort
guide forward so that the shoulder belt
does not sit close to the person’s neck.
The pretensioner helps the seat belt to
quickly restrain the occupant by
retracting the seat belt when the vehi-
cle 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.
■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 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. 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 for the child, until the child becomes large
enough to properly wear the vehicle’s seat belt. ( →P. 53)
●When the child becomes large enough to properly wear the vehicle’s seat belt, follow
the instructions regardin g seat belt usage. (→P. 30)
■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 extender
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.
WARNING
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 passeng ers 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.

WARNING
■Pregnant women
■People suffering illness
Obtain medical advice and wear the seat belt in the proper way. (→P. 30)
■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 othe r 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
●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. 30)
Obtain medical advice and wear the seat belt
in the proper way. ( →P. 30)
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.

WARNING
■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 correct ly, 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 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 restraint 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 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.
