FRONT SEATS
Front seat precautions
CAUTION
The SRS side airbags are installed in the driver and front
passenger seats. Observe the following precautions.
Do not lean over the front door when the vehicle is in use.
The side airbag inflates with considerable speed and force;
you may be killed or severely injured.
Do not modify or replace the seats or the surface of the seats
with side airbags. Such changes may disable the system, or
cause the side airbags to inflate, resulting in death or
serious injury. Consult your Lexus dealer.
Do not use accessories for the seats which cover the parts
where the side airbags should inflate. Such accessories may
prevent the side airbags from activating correctly, causing
death or serious injury.
Seat adjustment precautions
Adjust the driver’s seat so that the foot pedals, steering wheel and
instrument panel controls are within easy reach of the driver.
CAUTION
Do not adjust the seat while the vehicle is moving as the seat
may unexpectedly move and cause the driver to lose control
of the vehicle.
Be careful not to hit the seat against a passenger, luggage or
the rear seat.
NOTICE
Do not operate the control switch in more than one dimension
at a time. It may cause electrical overload.

Move the control switch in the desired direction.
Releasing the switch will stop the seatback in that position.
CAUTION
To reduce the risk of sliding under the lap belt during a
collision, avoid reclining the seatback any more than needed.
The seat belts provide maximum protection in a frontal or rear
collision when the driver and the passenger are sitting up
straight and well back in the seats. If you are reclined, the lap
belt may slide past your hips and apply restraint forces
directly to the abdomen. Therefore, in the event of a frontal
collision, the risk of personal injury may increase with
increasing recline of the seatback.
Adjusting seat cushion angle and height

SEAT BELTS
Seat belt precautions
Lexus strongly urges that the driver and passengers in the vehicle be
properly restrained at all times with the seat belts provided. Failure
to do so could increase the chance of injury and/or the severity of
injury in accidents.
Child. Use a child restraint system appropriate for the child until the
child becomes large enough to properly wear the vehicle’s seat belts.
See ”Child restraint” for details.
If a child is too large for a child restraint system, the child should sit
in the rear seat and must be restrained using the vehicle’s seat belt.
According to accident statistics, the child is safer when properly
restrained in the rear seat than in the front seat.
If a child must sit in the front seat, the seat belts should be worn
properly. Do not let the child sit on your lap. It does not provide
sufficient restraint. If an accident occurs and the seat belts are not
worn properly, the force of the rapid inflation of the airbag may cause
severe injury to the child.
Do not allow the child to stand up or kneel on either rear or front
seats. An unrestrained child could suffer serious injury during
emergency braking or a collision.Pregnant woman. Lexus recommends the use of a seat belt. Ask
your doctor for specific recommendations. The lap belt should be
worn securely and as low as possible over the hips and not on the
waist.
Injured person. Lexus recommends the use of a seat belt.
Depending on the injury, first check with your doctor for specific
recommendations.
CAUTION
Persons should ride in their seats properly wearing their seat
belts whenever the vehicle is moving. Otherwise, they are
much more likely to suffer serious bodily injury in the event
of sudden braking or a collision.
When using the seat belts, observe the following:
Use the belt for only one person at a time. Do not use a
single belt for two or more people even children.
Avoid reclining the seatbacks too much. The seat belts
provide maximum protection when the seatbacks are in the
upright position. (See ”Adjusting seatback angle”.)
Be careful not to damage the belt webbing or hardware.
Take care that they do not get caught or pinched in the seat
or doors.
Inspect the belt system periodically. Check for cuts,
fraying, and loose parts. Damaged parts should be
replaced. Do not disassemble or modify the system.

COMFORT ADJUSTMENT
81 Keep the belts clean and dry. If they need cleaning, use a
mild soap solution or lukewarm water. Never use bleach,
dye, or abrasive cleaners they may severely weaken the
belts.
Replace the belt assembly (including bolts) if it has been
used in a severe impact. The entire assembly should be
replaced even if damage is not obvious.
Front seat belt buckle illumination
16L020
Opening the driver’s door lights up the driver’s seat belt buckle
for easy use. The same applies for the front passenger’s door and
seat belt buckle.
The light remains on for 15 seconds after the door is closed, but goes
off immediately when all doors are locked.
Fastening front and rear seat belts
16L115-1
Adjust the seat as needed and sit up straight and well back in the
seat. To fasten your belt, pull it out of the retractor and insert the
tab into the buckle.
You will hear a click when the tab locks into the buckle.
The seat belt length automatically adjusts to your size and the seat
position.
The retractor will lock the belt during a sudden stop or on impact.
It also may lock if you lean forward too quickly. A slow, easy motion
will allow the belt to extend, and you can move around freely.
