Installation of an RF-transmitter system
The installation of an RF-transmitter system in your vehicle could affect electronic
systems such as:
●Multiport fuel injection system/sequential multiport fuel injection system
●Cruise control system
●Dynamic radar cruise control system
●Anti-lock brake system
●SRS airbag system
●Seat belt pretensioner system
Be sure to check with any authorized Lexus dealer or repairer, or another duly qual-
ified and equipped professional for precautionary measures or special instructions
regarding installation of an RF-transmitter system.
Further information regarding frequency bands, power levels, antenna positions
and installation provisions for the installation of RF-transmitters, is available on
request at any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional.
Scrapping of your Lexus
The SRS airbag and seat belt pretensioner devices in your Lexus contain explosive
chemicals. If the vehicle is scrapped with the airbags and seat belt pretensioners left
as they are, this may cause an accident such as fire. Be sure to have the systems of
the SRS airbag and seat belt pretensioner removed and disposed of by a qualified
service shop or by any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional, before you scrap your vehicle.

increasing the risk of death or serious injury in the event of an accident.
●Adjustments should not be made while driving as the seat may unexpectedly
move and cause the driver to lose control of the vehicle.
