Cruise Control: Adjustments



There is no provision for engagement-cruising speed zeroing. If cruising speed is too high or low, check vacuum hoses for improper routing, restrictions or leaks and servo linkage for proper adjustment. If cruising speed remains too high or low, replace the electronic controller.
