Installation of a mobile two-way radio system
The installation of a mobile two-way radio system in your vehicle could affect elec-
tronic systems such as:
●Multiport fuel injection system/sequential multiport fuel injection system
● Cruise control system
● Anti-lock brake system
● SRS airbag system
● Seat belt pretensioner system
Be sure to check with your Lexus dealer for precautionary measures or special
instructions regarding installation of a mobile two-way radio system.
High voltage parts and cables on the hybrid vehicles emit approximately the same
amount of electromagnetic waves as the conventional gasoline powered vehicles or
home electronic appliances despite of their electromagnetic shielding.
Unwanted noise may occur in the reception of the mobile two-way radio.
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 your Lexus dealer before you scrap your vehicle.
Perchlorate Material
Special handling may apply, See www.dtsc.ca.gov/hazardouswaste/perchlorate.
Your vehicle has components that may contain perchlorate. These components may
include airbag, seat belt pretensioners, and wireless remote control batteries.
