The installation of a mobile two-way radio system in your vehicle could affect
electronic systems such as:
● Hybrid system
● Multiport fuel injection system/sequential multiport fuel injection system
● Toyota Safety Sense P
● Cruise control system
● Anti-lock brake system
● SRS airbag system
● Seat belt pretensioner system
Be sure to check with your Toyota dealer for precautionary meas ures or spe-
cial instructions regarding instal lation of a mobile two-way radio system.
High voltage parts and cables on the hybrid vehicles emit appro ximately the
same amount of electromagnetic waves as the conventional gasoli ne pow-
ered vehicles or home electronic appliances despite of their el ectromagnetic
shielding.
Unwanted noise may occur in the reception of the mobile two-way radio.
