To resume cruising speed at more than approximately 25 mph (40 km/h)
Hyundai Accent / HYundai Accent 2011 Owners Manual / Features of your Hyundai / Cruise Control System / To resume cruising speed at more than approximately 25 mph (40 km/h)

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)
