If you press the O (CANCEL) button once, the set speed limit will cancel, but it will not turn the system off. If you wish to reset the speed limit, move the lever up (to RES+) or down (to SET-) on your steering wheel to your desired speed.
CAUTION
The “---” indicator will blink if there is a problem with speed limit control system.
If this occurs, we recommend that the system be checked by an authorized Kia dealer.
