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 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 precautions. Failure to follow these
instructions could reduce the 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, for
another person, or at a different seating position than
the one originally intended.
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.
When not in use, remove the extender and store in the vehicle
for future use.

Front seat belt pretensioners
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 if there is
no passenger sitting 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.
