Adjusting seatback angle
g16003
Move the control switch in the desired direction.
Releasing the switch will stop the seatback in that position.
CAUTION
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 front 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 or your
neck may contact the shoulder belt. In the event of a
frontal collision, the more the seat is reclined, the
greater the risk of death or personal injury .
Adjusting seat cushion angle and height

REAR SEATS
Rear seat precautions
Rear seats (with SRS rear side airbags)
CAUTION
The SRS rear side airbags are installed in the outboard
rear seats. Observe the following precautions.
Do not lean against the rear door when the vehicle is
in use, since the rear side airbag inflates with
considerable speed and force. Otherwise, you may
be killed or severely injured.
 Do not use seat accessories which cover the area
where the rear side airbags inflate. Such accessories
may prevent the rear side airbags from activating
correctly, causing death or serious injury.
 Do not modify or replace the outboard rear seats or
the upholstery of the seats equipped with rear side
airbags. Such change may prevent the side airbag
system from activating correctly, disable the system,
or cause the rear side airbags to inflate accidentally,
resulting in death or serious injury.

the highest (or lowest) position while the seat is being adjusted
backward (or forward), the head restraint will be fixed in that
position.

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.
The seat belts provided for your vehicle are designed for
people of adult size, large enough to properly wear them.
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” on page 178 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. If an accident occurs and the seat belts are not worn
properly, the force of the rapid inflation of the airbag may cause
death or serious injury to the child.
Do not allow any children to stand up or kneel on either rear or
front seats. An unrestrained child could suffer serious injury or
death during emergency braking or a collision. Also, do not let
the child sit on your lap. Holding a child in your arms does not
provide sufficient restraint.
