Installation of a mobile two-way radio system
As the installation of a mobile two-way ra dio system in your vehicle could affect
electronic systems such as the hybrid system, multiport fuel injection system/
sequential multiport fuel injection system , cruise control system, vehicle dynamics
integrated management, SRS airbag system and seat belt pretensioner system, be
sure to check with your Lexus dealer for precautionary measures or special instruc-

High voltage parts and cables on the hybr id 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.

●Do not wear the seat belt extender, if you can fasten the seat belt without the
extender.
●Do not use the seat belt extender when installing a child restraint system, because
the belt will not securely hold the child restraint system, increasing the risk of
death or injury in the event of a collision.

another person, or at a different seating position other than the one originally
intended.
