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

If belt does not buckle, continue with Step 3.
If buckle latches but belt has no slack remaining, continue with Step 3.
3. Measure distance between applicant's navel and seat belt buckle (Dimension A) and enter on Worksheet.
4. With belt all the way out, measure distance between latch tip and buckle tip (Dimension B) and enter
on Worksheet.
NOTE: If belt latches but there is no slack enter zero as Dimension B.
5. Subtract Dimension B from Dimension A and record number in Check Number box on Worksheet.
6. Seat Belt Extender length is Dimension B rounded up to next extender length (without exceeding
Check Number).
NOTE: If extender length exceeds Check Number, an extender cannot
be provided to the customer.
CAUTION:
On vehicles equipped with SRS Ð Occupant Classification System (OCS), it is critical that the extender

TSIB UPDATE NOTICE:
The information contained in this TSIB supercedes TSIB No. BO004-98.
TSIB No. BO004-98 is now obsolete and should be discarded.
Beginning in 1997, Lexus introduced side airbags for the LS 400. Starting with 1998,
all Lexus vehicles are equipped with side airbags as standard equipment.
Lexus does NOT recommend replacement of original seat covers* with non-Lexus leather
or other seat cover materials due to the following:
Seat covers NOT recommended by Lexus may affect side airbag performance, in
general or in part, during an accident.
Modifications that negatively affect side airbag performance can result in severe
occupant injuries.
Seat covers are an integral part of this safety system. Replacing original seat covers*
with non-Lexus leather or other seat cover materials may compromise the
effectiveness of this safety system.
The design of the seat is complex, integrating safety and strength with comfort
and luxury.
*NOTE:
Lexus original seat covers that were NOT designed for side airbag equipped seats
cannot be used due to the effect on proper airbag performance.
Lexus strongly discourages modifying original equipment seats that have
side airbags.
Additionally, Lexus strongly advises against the installation or use of aftermarket
seat covers, which could impair the performance of the side airbags in the event of
an accident.
All 1997 ± 2006 model year Lexus vehicles.
