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
