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 death or serious 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 the driver actually
wearing the seat belt, the SRS driver’s airbag system
will judge that the driver is 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.
Make sure the front passenger occupant
classification indicator li ght indicates “ON” when
using the seat belt extender for the front passenger
seat. If the indicator light indicates “OFF”,
disconnect the extender t ongue from the seat belt
buckle, then reconnect the seat belt. Reconnect the
seat belt extender after making sure the indicator
light indicates “ON”. If you use the seat belt extender
while the indicator light indicates “OFF”, the front
passenger airbag and side airbag on the front
passenger side may not ac tivate correctly, which
could cause death or serious injury in the event of
collision.
 Do not use the seat belt extender if it is not absolutely
necessary.
 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 “PRESS” 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.
As far as the seat belt extender on the front passenger side is
concerned, do not fail to disconnect the extender from the seat
belt after the above operation in order to activate the front
passenger airbag correctly when getting into the vehicle next
time.
When not in use, remove the extender and store in the vehicle
for future use.
CAUTION
 After inserting the tab, make sure the tab and buckle
are locked and that the lap and shoulder portions of
the belt and the seat belt extender are 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 death or
serious injury.

Seat belt pretensioners
16X620
The driver and front passenger seat belt pretensioners are
designed to be activated in response to a severe frontal
impact or a vehicle rollover.
When the sensor detects a severe frontal impact or a vehicle
rollover, the front seat belts are quickly drawn back by the
retractor so that the belts snugly restrain the occupants.
The front passenger’s seat belt pretensioner will not activate
if no passenger is detected in the front passenger seat by the
front passenger occupant classification system. However, the
front passenger’s seat belt pretensioner may activate if
luggage is put on the seat, or the seat belt is buckled up
regardless of the presence of an occupant in the seat. (As for
the front passenger occupant classification system, see page
157.)
The seat belt pretensioners and SRS airbags may not operate
together in all collisions.

 Roll sensing of curtain shield airbags off indicator light
The seat belt pretensioners will not operate in a vehicle rollover
if the roll sensing of curtain shield airbags off indicator light is
on. For details, see “Roll sensing of curtain shield airbags off
switch” on page 45.

OCCUPANT RESTRAINT SYSTEMS
131
CAUTION
Make sure the roll sensing of curtain shield airbags
off indicator light is not on.
 When the roll sensing of curtain shield airbags off
switch is turned on (and the roll sensing of curtain
shield airbags off indicator light is on), the seat belt
pretensioners will not operate in a vehicle rollover
and turning off the seat belt pretensioners can
reduce the occupant protection which your vehicle
safety systems can provide to you in certain
accidents and increase the likelihood of death or
serious personal injuries.

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

CAUTION
Do not modify, remove, strike or open the seat belt
pretensioner assemblies, airbag sensor or
surrounding area or wiring. Failure to follow these
instructions may prevent the seat belt pretensioners
from activating correctly, cause sudden operation of
the system or disable the system, which could result
in death or serious injury.
 Do not use tires or wheels other than the
manufacturer’s recommended size. Such a use may
cause the curtain shield airbags and seat belt
pretensioners to inflate accidentally, resulting in
death or serious injury. For details, see “Checking
and replacing tires” on page 438.
 Do not place luggage heavier than specified on the
roof luggage carrier. Such luggage may cause the
curtain shield airbags and seat belt pretensioners to
inflate accidentally, resulting in death or serious
injury. For details, see “Roof luggage carrier” on
page 88.
 Do not modify or change the suspension system.
Such changes may cause the curtain shield airbags
to inflate accidentally, resulting in death or serious
injury.
Failure to follow these instructions can result in death
or serious injury. Consult your Lexus dealer before
performing any repair and modification.
NOTICE
Do not perform any of the following changes without
consulting your Lexus dealer. Such changes can
interfere with proper operation of the seat belt
pretensioners in some cases.
 Installation of electronic devices such as a mobile
twoway radio, cassette tape player or CD player.
 Repairs on or near the seat belt retractor assemblies.
 Modification of the front end structure.
 Attachment of a grille guard (bull bar, kangaroo bar,
etc.), snowplow, winches or any other equipment to
the front end.
 Repairs made on or near the front fenders, front end
structure or console.
