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.

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
People suffering illness
Obtain medical advice and wear the seat belt in the proper way. (P. 3 8 )
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 inju-
ries 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
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 any
authorized Lexus dealer or repairer, or another duly qualified and equipped
professional.
Adjustable shoulder anchor
Always make sure the shoulder belt is positioned 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. 3 9 )
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 correctly, immediately contact any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional.
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 any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
Inappropriate handling may lead to incorrect operation.

Safety information for children
It is recommended that children sit in the rear seats to avoid acci-
dental contact with the shift lever, wiper switch etc.
Use the rear door child-protector lock or the window lock switch
to avoid children opening the door while driving or operating the
power window accidentally. (P. 184, 215)
Do not let small children operate equipment which may catch or
pinch body parts, such as the power window, hood, trunk, seats
etc.
Observe the following precautions when children are in the vehi-
cle.
Use a child restraint system appropriate for the child, until the
child becomes large enough to properly wear the vehicle’s seat
belt.
CAUTION
Never leave children unattended in the vehicle, and never allow children to
have or use the key.
Children may be able to start the vehicle or shift the vehicle into neutral.
There is also a danger that children may injure themselves by playing with
the windows, the moon roof or other features of the vehicle. In addition,
heat build-up or extremely cold temperatures inside the vehicle can be fatal
to children.
