Failure to follow the recommendations indicated below could result in reduced
effectiveness of the seat belt restraint system in case of vehicle collision, causing
personal injury.
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 visit your local Lexus dealer so that the dealer can order the proper required
length 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.
When the Seat Belt Extender is provided for rear seat positions (with automatic locking
retractor), make sure that the retractor is locked when in use.
To connect the extender to the seat
belt, insert the tab into the seat belt
buckle so that 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 not in use, remove the extender
and store in the vehicle for future use.
CAUTION:
On vehicles equipped with SRS ± Occupant Classification System (OCS)*, it is
critical that the extender tab be buckled into the buckle AFTER the occupant sits
down in the seat.
Leaving extender installed in the buckle before sitting down will cause the OCS to be
in the ªairbag offº or disarmed state.
* OCS will enable or disable the passenger front and side airbags based on passenger weight and seat belt
latch position classifying the passenger as a child or adult.
CAUTION:
When using the Seat Belt Extender, observe the following. Failure to follow these
instructions could result in reduced 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 COMFORTABLY fasten the seat belt
without it.
The Seat Belt Extender must never be used with any child safety seats.
Remember that the extender provided for you may not be safe when used on a
different vehicle, for another person or for a different seating position than the one
originally intended.September 29, 2004

Title:
PASSENGER AIRBAG INDICATOR LAMP
Models:
'04 ± '05 ES 330 & RX 330
Technical Service
Information Bulletin
February 22, 2005
EL002-05
The passenger airbag indicator lamp may switch from ON to OFF for front seat
passengers weighing approximately less than 100 pounds, depending on their seating
position. It is important for the front seat passengers to know that proper operation of the
advanced frontal airbag system is highly dependent on the pressure placed on the seat
bottom. Situations that add or subtract sensed weight can result in occupant
misclassification. To minimize this situation:
Check seating posture.
± Passengers should be seated upright with their back against the seatback and
feet on the floor.
Check loading conditions.
± Extra weight from items such as bags or groceries or toys hanging on the
seatback can add to the sensed weight of the front seat passenger.
± A rear seat passenger lifting the front seat with their legs, objects placed under
the front seat, or the front seatback in contact with the rear seat can subtract from
the sensed weight of the front seat passenger.
If the passenger airbag indicator lamp continues to switch ON to OFF after checking the
above conditions, perform the following repair procedure.
NOTE:
The safest place for children is in the rear seat.
Please note that Lexus recommends
that you NEVER
install a rear±facing child restraint in the front passenger seat, even if
the passenger ªAirbag OFFº lamp is illuminated. Please refer to the Owner's Manual
for additional details.
