When Smart Cruise Control works

The manual lists the operating conditions: the gear is in D (Drive), ESC and ABS are on, and the speed is within range, which is 5 to 110 mph (10-180 km/h) when there is no vehicle in front and 0 to 110 mph (0-180 km/h) when there is one. When stopped behind another vehicle, you can turn SCC on while holding the brake pedal.

• SCC does not operate when engine rpm is high, the driver's door is open or the Electronic Parking Brake is applied.
• It also does not operate while ESC or ABS is controlling the vehicle, while Forward Collision-Avoidance Assist brake control or Remote Smart Parking Assist brake control is working, or while a Lane Keeping Assist or Highway Driving Assist hands-off warning is on.

The Santa Fe page on hyundaiusa.com, read November 4, 2026, lists Smart Cruise Control with Stop & Go, including Smart Cruise Control 2 (SCC2), among the Santa Fe's driver assistance features, standard on the SEL, XRT, Limited and Calligraphy trims, and says SCC2 is for highway use only and should not be used in poor weather, heavy or varying traffic, or on winding or slippery roads. The manual adds that SCC may not operate for a few seconds after the vehicle is started or the camera or radar is initialized.

Turning it on and setting your speed

Press the Driving Assist button. The set speed becomes your current speed, or 20 mph (30 km/h) if you are going between 0 and 20 mph. With no vehicle ahead the set speed is held; with one ahead, SCC slows to keep your distance, then accelerates back to the set speed when the road clears.

• Push the + switch up and release: the set speed rises 1 mph. Push and hold: it rises 5 mph at a time, up to 110 mph (180 km/h).
• Push the - switch down and release: the set speed drops 1 mph. Push and hold: it drops 5 mph at a time, down to 20 mph (30 km/h).
• Press the accelerator to speed up temporarily without changing the set speed; the set speed and distance blink on the cluster while you do.

Hyundai warns that speed and distance are not controlled automatically while you are pressing the accelerator, and that the speed may not reach the set speed depending on driving conditions. Overtaking Acceleration Assist can briefly add speed when you signal left above 40 mph (60 km/h) with a vehicle ahead.

The four following distances

From Smart Cruise Control Operation in the 2027 Santa Fe owner's manual, page 541. Press the distance button repeatedly to cycle 4, 3, 2, 1 and back to 4. The last distance you chose is kept when the vehicle is restarted.

In the infotainment settings (Setup > Vehicle > Driver Assistance > Driving Convenience > Smart Cruise Control) you can adjust vehicle distance, acceleration and reaction speed. Vehicles with Based on Driving Style can instead learn these from how you drive.

Stop and go in traffic

In traffic, your vehicle stops when the vehicle ahead stops, and starts again when it moves off. After you have been stopped for a certain time, a "Use switch or pedal to accelerate" message appears; press the accelerator or use the +, - or resume switch to go. If SCC is canceled while you are at a standstill, the manual says the Electronic Parking Brake may be applied.

Two more alerts matter in traffic. "Watch for surrounding vehicles" appears when the vehicle you were following disappears at low speed, and "Collision Warning" appears with a chime and steering wheel vibration when the risk of hitting the vehicle ahead is high. Both mean it is time to brake yourself if needed.

Cancel, resume and turn off

From Smart Cruise Control Operation in the 2027 Santa Fe owner's manual, pages 543 to 545. Hyundai warns that speed can change sharply when you press resume, and not to use the switches and buttons at the same time.

When SCC cancels on its own

The manual says Smart Cruise Control cancels temporarily, with a "Smart Cruise Control deactivated" message and a chime, when:

• the vehicle speed is above 120 mph (190 km/h)
• the vehicle is stopped for a certain period of time
• the accelerator pedal is held down for a certain period of time
• the operating conditions above are no longer met

Once canceled, the distance to the vehicle ahead is no longer maintained, so be ready to brake. If the front radar cover is covered with snow, rain or debris, a "Driver Assistance system limited. Radar blocked." message can appear and SCC may be limited until it is cleaned. A "Check Driver Assistance system" message with the warning light means the vehicle should be inspected by an authorized Hyundai dealer.

Situations Hyundai says SCC may not handle

Smart Cruise Control does not replace attentive driving. The manual lists many conditions where it may not operate properly or may act unexpectedly, including:

• heavy rain, snow or fog, sun glare, or a dirty, frosted or obstructed windshield or radar area
• curves and hills, where it may not see a vehicle in your lane and may speed up to the set speed, then slow sharply when it does
• vehicles cutting in suddenly, vehicles offset to one side, motorcycles, bicycles, pedestrians and animals, and stopped or oncoming vehicles
• tunnels, iron bridges, construction zones, highway interchanges and tollbooths, and slippery roads
• parking lots, roundabouts and continuous circling

Hyundai also says to keep SCC off when you are not using it, to turn it off when towing a trailer or when your vehicle is being towed, and never to open the door or leave the vehicle while SCC is operating, even when stopped. If the camera or radar needs attention, our service team can check them; you can schedule service online.
