Cruise Control System: Notes
The cruise control allows you to cruise the vehicle at a desired speed over 25 mph (40 km/h) even with your foot off the accelerator pedal. See Fig 1.
Your cruising speed can be maintained up or down grades within the limits of engine performance, although a slight speed change may occur when driving up or down the grades. On steeper hills, a greater speed change will occur so it is better to drive without the cruise control.
