Seat belt extender
If your seat belt cannot be fastened securely because it is 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. Failure to follow these instructions could
result in less 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, or for
another person or at a different seating position than
the one originally intended for.

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.

an adult occupant or your child from injury.
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, door 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 38.)

4Airbag sensor assembly
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.

Move seat fully back
A forward±facing child restraint system should be
allowed to be put on the front seat only when it is
unavoidable. Always move the seat as far back as
possible, because the force of a deploying airbag
could cause death or serious injury to the child. Do
not allow the child to lean over the front door or
around the front door even if the child is seated in a
child restraint system. It is dangerous if the side
airbag inflates, and the impact could cause death or
serious injury to the child.

1. Sit the child on a booster seat. Run the lap and shoulder belt
through or around the booster seat and child following the
instructions provided by its manufacturer and insert the tab into
the buckle.
Make sure the shoulder belt is correctly across the child's
shoulder and that the lap belt is positioned as low as possible
on child's hips. See ºSeat beltsº on page 81 for details.
CAUTION
 Always make sure the shoulder belt is positioned
across the center of child's shoulder. The belt should
be kept away from child's neck, but not falling off
child's shoulder. Failure to do so could reduce the
amount of protection in an accident and cause
serious injuries in a collision.
 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 child's hip as possible.
 For child's safety, do not place the shoulder belt
under child's arm.
 After inserting the tab, make sure the tab and buckle
are locked and that the lap and shoulder portions of
the belt are not twisted.
 Do not insert coins, clips, etc. in the buckle as this
may prevent your child from properly latching the tab
and buckle.
