Cruise Control System: Notes
WARNING: This page is about a different car, the 2003 Lexus ES 300 and 2002 Lexus ES 300. However, it is still accessible from the selected car via links, so may be relevant.
The cruise control allows you to cruise the vehicle at a desired speed over 25 mph (40 km/h) with your foot off the accelerator pedal. Your cruising speed can be maintained although a slight speed change may occur when driving up or down a gradient, within the limits of engine performance. On steeper hills, a great speed change will occur so it is better to drive without the cruise control on.
