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 ºChild restraintº on
page 104.) 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. It cannot protect
an adult occupant or your child from injury.

Adjust the position of the lap and shoulder belts.
1
Position the lap belt as low as possible on your hips ± not
on your waist.
2 Adjust 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 result. Keep the lap belt positioned as
low on hips as possible.
 For your safety, do not place the shoulder belt under
your arm.

Adjust the shoulder anchor position to your size.
To raise the anchor position, push the anchor up. To lower the
anchor position, support the anchor while you push the lock
release button then 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 severe injuries in a
collision.
SV16016
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.

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 vehicle accident,
increasing the chance of personal injury.
Never use the seat belt extender if you can fasten the
seat belt without it.
 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.
SV16050
To connect the extender to the seat belt, insert the tab into
the seat belt buckle so that the ºPRESSº 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.

Front seat belt pretensioners
SV16069
The driver and front passenger's seat belt pretensioners
are designed to be activated in response to a severe
frontal impact.
When the airbag sensor detects the shock of a severe frontal
impact, the front seat belts are quickly drawn back by the
retractor so that the belts snugly restrain the front seat
occupants.
The front seat belt pretensioners are activated even with no
passenger in the front seat.
Collisions occurring at certain speeds and angles may cause
the seat belt pretensioners and SRS airbags not to operate all
together.

This indicator comes on when the ignition key is turned to
the ºACCº or ºONº position. It goes off after about 6
seconds. This means the front seat belt pretensioners are
operating properly.
The warning light system monitors the airbag sensor
assembly, front airbag sensors, side airbag sensors, front seat
belt pretensioner assemblies, inflators, warning light,
interconnecting wiring and power sources. (For details, see
ºService reminder indicators and warning buzzersº on page

The front seat belt pretensioner system consists mainly of the
above components and their locations are shown in the
illustration.
The front seat belt pretensioners are controlled by the airbag
sensor assembly. The airbag sensor assembly consists of a
safing sensor and airbag sensor.
When the front seat belt pretensioners are activated, an
operating noise may be heard and a small amount of
smoke±like gas may be released. This gas is harmless and
does not indicate that a fire is occurring.
Once the front seat belt pretensioners have been activated, the
seat belt retractors remain locked.
