#7 of 10 Silverado Cruise Control by gundoctor Feb 20, 2007 (5:34 pm)
My cruise control works during the daytime, but when the lights come on (other than daylight driving lights) or I manually turn them on, my cruise control quits working in less than a minute. Cannot set the cruise control while lights are on. As soon as I turn the lights off, cruise will work again. Any ideas? Replies to this message: repairdog (Feb 20, 2007 5:38 pm)

#9 of 10 cruise control and fuel efficiency by jmosby1469 Oct 06, 2008 (3:35 pm)
The conventional wisdom that the use of cruise control helps improve fuel economy, by evening out the accelerations and decelerations involved in usual driving practices, has a flaw. I notice that using this feature on roads with varying terrains, including many hills, results in my RPM's increasing sharply as my vehicle ascends these hills. I believe these sudden sharp increases in my engine's output negates many benefits to fuel economy of keeping the cruise control set. Your comments, please.

Replying to: jmosby1469 (Oct 06, 2008 3:35 pm) You are correct. Cruise control is not effective for fuel economy in rolling terrain as it cannot "look ahead" and compensate. Nor can it "average" such as letting the car gain a few MPH leading up to a hill, or drop a few extra MPH while approaching the crown of a hill.
