NOTICE
Avoid putting heavy loads on the removed seats. The
metallic tips of the seat legs may be damaged and the
seats cannot be reinstalled.
To return them to the original positions, reverse the steps
above.
CAUTION
When removing or reinstalling the seats, observe the
following to prevent personal injury:
Do not remove or reinstall the seats while the vehicle
is moving.
Be careful not to get your hands or feet pinched in the
seats.
Be careful not to hit the removed seats against a
person or drop it on yourself.
Do not try to sit on or place anything on the removed
seat.
To prevent personal injury in a collision or sudden stop:
Do not sit on or place anything on the folded seatback
while driving.
Do not leave the removed seat loose in the vehicle.
After reinstalling the seats, make sure the seats are
securely locked by pushing forward and rearward on
the top of the seatbacks or by trying to pull up the
edge of the bottom cushions. Failure to do so will
prevent the seat belt from operating properly.
Install each seat in the same position from which it
was removed. Failure to do so will prevent third seat
occupants from using seat belts properly.
Make sure the seat belts are not twisted or caught
under the seat and are arranged in their proper
position and are ready to use.

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 restraintº on page 176 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.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 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 Ð even children.
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 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. In the event of a
frontal collision, the more the seat is reclined, the
greater the risk of personal injury.

Fastening front, second and third seat belts
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.When a passenger's shoulder belt is completely extended and
is then retracted even slightly, the belt is locked in that position
and cannot be extended. This feature is used to hold the child
restraint system securely. (For details, see Child restraintº on
page 176.) To free the belt again, fully retract the belt and then
pull the belt out once more.
If the seat belt cannot be pulled out of the retractor, firmly pull
the belt and release it. You will then be able to smoothly pull
the belt out of the retractor.
CAUTION
After inserting the tab, make sure the tab and buckle
are locked and that the belt is not twisted.
Do not insert coins, clips, etc. in the buckle as this
may prevent you from properly latching the tab and
buckle.
If the seat belt does not function normally,
immediately contact your Lexus dealer. Do not use
the seat until the seat belt is fixed, because it cannot
protect an adult occupant or your child from injury.

To release the belt, press the buckle release button and
allow the belt to retract.
If the belt does not retract smoothly, pull it out and check for
kinks or twists. Then make sure it remains untwisted as it
retracts.
CAUTION
Do not separate the buckle with light gray buckle
release button. Otherwise, the seat belt may not work
properly. See the information in the following columns.
Third center seat belt

Buckle with light gray buckle-release button
The third center seat belt is a 3-point type restraint with 2
buckles. Both seat belt buckles must be correctly located and
securely latched for proper operation.
Make sure that buckle with light gray buckle-release button is
securely latched for ready use of the center seat belt.

CAUTION
Do not use the third center seat belt with either buckle
release. Fastening only the shoulder belt or lap belt may
cause severe personal injury in case of sudden braking
or a collision.
STOWING THE THIRD CENTER SEAT BELT
Stow the seat belt tabs into the cover of the roof as shown
above.
Make sure the tabs are securely locked in the cover.
PULLING OUT THE THIRD CENTER SEAT BELT
Pull the belt out a little and pull the tabs out from the cover.

Seat belt extender
If your seat belts cannot be fastened securely because they are
not long enough, a personalized seat belt extender is available
from your Lexus dealer free of charge.
Please contact your local Lexus dealer to order the proper
required length for the extender. Bring the heaviest coat you
expect to wear for proper measurement and selection of
length. Additional ordering information is available at your
Lexus dealer.
CAUTION
When using the seat belt extender, observe the
following precautions. Failure to follow these
instructions could reduce the effectiveness of the seat
belt restraint system in case of an accident, increasing
the chance of personal injury.
Remember that the extender provided for you may
not be safe when used on a different vehicle, for
another person, or at a different seating position than
the one originally intended.If the seat belt extender has been connected to the
driver's seat belt buckle without wearing the seat belt
when using the extender in the driver's seat, the SRS
driver's airbag system will judge that the driver wears
the seat belt even if not wearing it. In this case, the
driver's airbag may not activate correctly, causing
death or serious injury in the event of collision. Be
sure to wear the seat belt with the seat belt extender.

OCCUPANT RESTRAINT SYSTEMS
144
Be sure to wear the seat belt without the seat belt
extender if you can fasten the seat belt without the
extender.
Do not use the seat belt extender when installing a
child restraint system on the front or rear passenger
seat. If installing a child restraint system with the
seat belt extender connected to the seat belt, the seat
belt will not securely hold the child restraint system,
which could cause death or serious injury to the child
or other passengers in the event of collision.
To connect the extender to the seat belt, insert the tab into
the seat belt buckle so that the PRESSº signs on the
buckle release buttons of the extender and the seat belt
are both facing outward as shown.
You will hear a click when the tab locks into the buckle.
When releasing the seat belt, press on the buckle release
button on the extender, not on the seat belt. This helps prevent
damage to the vehicle interior and extender itself.
When not in use, remove the extender and store in the vehicle
for future use.

OCCUPANT RESTRAINT SYSTEMS
150Always wear your seat belt properly.
Your vehicle is equipped with a crash sensing and diagnostic
module, which will record the use of the seat belt restraint
system by the driver and front passenger when the SRS front
airbags are inflated.
CAUTION
The SRS front airbag system is designed only as a
supplement to the primary protection of the driver
and front passenger seat belt systems. The driver
and front passenger can be killed or seriously injured
by the inflating airbags if they do not wear the
available seat belts properly. During sudden braking
just before a collision, an unrestrained driver or front
passenger can move forward into direct contact with
or close proximity to the airbag which may then
deploy during the collision. To ensure maximum
protection in an accident, the driver and all
passengers in the vehicle must wear their seat belts
properly. Wearing a seat belt properly during an
accident reduces the chances of death or serious
injury or being thrown out of the vehicle. For
instructions and precautions concerning the seat
belt system, see Seat beltsº on page 135.
Improperly seated and/or restrained infants and
children can be killed or seriously injured by the
deploying airbags. 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 second or third seat of the vehicle and properly
restrained. The second or third seat is the safest for
infants and children. For instructions concerning the
installation of a child restraint system, see Child
restraintº on page 176.
The SRS front airbags are designed to deploy in severe
(usually frontal) collisions where the magnitude and
duration of the forward deceleration of the vehicle
exceeds the designed threshold level.
