If any method other than the CRUISE ONOFF switch was used to cancel cruising speed and the system is still activated, the most recent set speed will automatically resume when the RES/+ switch is pushed. It will not resume, however, if the vehicle speed has dropped below approximately 25 mph (40 km/h)
