PRIUS c_UThe installation of a mobile two-way radio system in your vehic
le could affect
electronic systems such as:
● Multiport fuel injection system/sequential multiport fuel injection system
● Toyota Safety Sense C
● 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.

■ Eco score
●As the accelerator pedal is not depressed, the driven distance using cruise
control (if equipped) is not included in the eco score.
● As the eco score evaluation differs according to driving conditions and envi-
ronmental factors, in some cases it may not be linked to fuel c onsumption.
■ Eco savings
●Fuel cost and savings should be used as a guide only.
● Depending on refueling methods, driving conditions and environm ental fac-
tors, the actual and displayed fuel costs may differ.
● In some cases, fuel cost and savings may not be linked to the eco score
evaluation.

●Clock
● Past record (aside from the top 3 results)
