To resume Smart Cruise Control set speed

If any method other than the cruise toggle switch was used to cancel cruising speed and the system is still activated, the cruising speed will automatically resume when you push the toggle switch up (RES+) or down (SET-).
If you push the toggle switch up (RES+), the speed will resume to the recently set speed. However, if vehicle speed drops below 10 km/h (5 mph), it will resume when there is a vehicle in front of your vehicle.

NOTICE
Always check the road conditions when you push the toggle switch up (RES+) to resume speed.
