For safety drive
Adjust the angle of the seat-
back so that you are sitting
straight up and so that you do
not have to lean forward to
steer. (P. 194)
Adjust the seat so that you can
depress the pedals fully and so
that your arms bend slightly at
the elbow when gripping the
steering wheel. (P. 194)
Lock the head restraint in
place with the center of the
head restraint closest to the top
of your ears. (P. 204)
Wear the seat belt correctly.
(P. 38)
Make sure that all occupants are wearing their seat belts before
driving the vehicle. (P. 38)
Use a child restraint system appropriate for the child until the child
becomes large enough to properly wear the vehicle’s seat belt. (P.
59)
For safe driving, adjust the seat and mirror to an appropriate posi-
tion before driving.

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 so that you can move around fully.
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. 5 9 )
When the child becomes large enough to properly wear the vehicle’s seat
belt, follow the instructions regarding seat belt usage. (P. 3 8 )
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 colli-
sions.
Seat belt regulations
If seat belt regulations exist in the country where you reside, please contact
any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional for seat belt replacement or installation.

CAUTION
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 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.
To achieve a proper seating position, do not recline the seat more than
necessary. 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.
Pregnant women
Obtain medical advice and wear the seat
belt in the proper way. (P. 3 8 )
Women who are pregnant should posi-
tion 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 avoid-
ing 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 colli-

CAUTION
SRS airbag precautions
The SRS front passenger airbag also deploys with considerable force, and
can cause death or serious injury especially if the front passenger is very
close to the airbag. The front passenger seat should be as far from the air-
bag as possible with the seatback adjusted, so the front passenger sits
upright.
Improperly seated and/or restrained infants and children can be killed or
seriously injured by a deploying airbag. An infant or child who is too
small to use a seat belt should be properly secured using a child restraint
system. Lexus strongly recommends that all infants and children be
placed in the rear seats of the vehicle and properly restrained. The rear
seats are safer for infants and children than the front passenger seat. (P.
59)
Do not sit on the edge of the seat or lean
against the dashboard.
Do not allow a child to stand in front of
the SRS front passenger airbag unit or
sit on the knees of a front passenger.
Do not allow the front seat occupants to
hold items on their knees.
Do not lean against the door, the roof
side rail or the front, side and rear pil-
lars.
