Fastening front and rear seat belts
SV16013
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 ªChild restraintº on
page 141.) 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.

Adjust the position of the lap and shoulder belts.
1Position the lap belt as low as possible on your hips ± not
on your waist.
2Adjust it to a snug fit by pulling the shoulder portion
upward through the latch plate.
CAUTION
 Both high±positioned lap belts and loose±fitting
belts could cause serious injuries due to sliding
under the lap belt during a collision or other
unintended event. Keep the lap belt positioned as low
on hips as possible.
 Do not place the shoulder belt under your arm.
SV16015

Seat belts with an adjustable shoulder anchor
Adjust the shoulder anchor position to your size.
To raise: Slide the anchor up.
To lower: Push in the lock release button and slide the anchor
down.
After adjustment, make sure the anchor is locked in position.
CAUTION
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 serious injuries in
a collision.

Pulling out the rear center seat belt
SV16108
To use the rear center seat belt, press ªPUSHº mark and

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 so that the dealer can
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.

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.
SV16050
To connect the extender to the seat belt, insert the tab into
the seat belt buckle so that the ªPRESSº 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 ext ender, 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.
