Hyundai Tucson: Intelligent Speed Limit Assist (ISLA) / Intelligent Speed Limit Assist Operation

Intelligent Speed Limit Assist may warn and control your vehicle by "Displaying speed limit", "Warning overspeed" , and "Changing set speed".


Intelligent Speed Limit operation is described based on the offset adjusted to "0". For more information on setting the offset, refer to "Speed Limit Offset" in this section.

Displaying speed limit

Speed limit information appears on the instrument cluster.

  • If the speed limit information of the road cannot be recognized, "---" appears.
  • Intelligent Speed Limit Assist provides additional road sign information in addition to speed limit information. Additional road sign information provided may differ depending on your country.
  • The images and colors in the instrument cluster may differ depending on the cluster type or theme selected from the settings menu.

Warning overspeed

When driving at a speed higher than the displayed speed limit, the speed limit appears in red.

Changing set speed

If the speed limit changes when using Manual Speed Limit Assist or Smart Cruise Control, an arrow in the direction of up or down appears to inform you to change the set speed by pushing the + or – switch.


  • If you want to drive below the speed limit, set the Speed Limit Offset under "0" or use the – switch on the steering wheel to lower the set speed. If the Speed Limit Offset is set over "0", the set speed changes to a speed higher than the limit for the road.
  • If necessary, reduce your driving speed as needed. Even after changing the set speed according to the speed limit for the road, your vehicle can still be driven over the speed limit.
  • If the speed limit for the road is under 20 mph (30 km/h), the set speed changing function does not work.
  • Intelligent Speed Limit Assist operates using the speed unit set by you from the settings menu. If the speed unit is set to a unit other than the speed unit used in your country, Intelligent Speed Limit Assist may not operate properly.


  • For more information on Manual Speed Limit Assist operation, refer to the "Manual Speed Limit Assist (MSLA)" section in this chapter.
  • For more details on Smart Cruise Control operation, refer to the "Smart Cruise Control (SCC)" section in this chapter.
