DESCRIPTION
The cruise control main switch is used to turn the dynamic radar cruise control system on and off, as well as operate 7 functions: SET, - (COAST), TAP-DOWN, RES (RESUME), + (ACCEL), TAP-UP and CANCEL.
The SET, TAP-DOWN and - (COAST) functions, and the RES (RESUME), TAP-UP and + (ACCEL) functions are operated with the same switch. The cruise control main switch contains momentary type contacts for each function. The contacts close only while the cruise control main switch is being operated in the direction of the relative function arrow, and open when the cruise control main switch is released. The voltage at the terminal of the hybrid vehicle control ECU assembly changes as each of the different contacts open or close. The hybrid vehicle control ECU assembly reads this voltage and controls the SET, - (COAST), RES (RESUME), + (ACCEL), and CANCEL functions accordingly.
