The FJ cruise control is perhaps the worst system I've ever had the displeasure to use. I drive primarily in Indiana (flat as a table) and I have found that using the cc is one of the most effective ways to decrease your mpg substantially. CONSTANTLY shifts from 2500rpm to 4000rpm in some of the most pointless of situations.
Yes, thank you!! The FJ has the absolute worst cruise control of any vehicle I have ever owned.So explain why it is possible to climb the same hill with out cruise control, and not have the transmission down shift? If it were gearing, then it would do the same function no matter if you were controlling the accelerator or if the computer controlled cruise control was. There fore, it is NOT gearing.
