Move the control switch in the desired direction.
Releasing the switch will stop the seat and head restraint in
that position. Do not place anything under the seat, as this
might interfere with the seat movement.

OCCUPANT RESTRAINT SYSTEMS
146
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
G16004
Move the control switch in the desired direction.
Releasing the switch will stop the seat cushion in that position.

OCCUPANT RESTRAINT SYSTEMS

The amount of lumbar support will change while the switch is
pushed.
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 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.

Driver’s seat
The height of the driver’s head restraint is automatically
adjusted along with the seat position movement when the

After adjusting the head restraint manually, even if you adjust
the seat to the foremost (or rearmost) position using seat
position control, the head restraint may not be adjusted to the
lowest (or highest) position. And if the head restraint reaches
the highest (or lowest) position while the seat is being adjusted
backward (or forward), the head restraint will be fixed in that
position.
G16130
To move the head restraint forward or rearward, move the
head restraint as shown.
The head restraint is most effective when it is close to your
head. Therefore, using a cush ion on the seatback is not
recommended.

closest to the top of your ears.

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 182 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.

OCCUPANT RESTRAINT SYSTEMS
152Pregnant
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 or death 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 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.
 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.
 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, or allow them
to come into contact with the belts they may
severely weaken the belts. (See “Cleaning the
interior” on page 604 for instructions.)
 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.
