Smart Cruise Control (SCC).

Smart Cruise Control (SCC) with Stop & Go detects the speed and distance of vehicles ahead of the Tucson. SCC maintains a safe distance to the vehicle ahead, up to a pre-set speed (between 30km/h – 180km/h).
The Stop & Go function works in stop/start traffic, bringing the vehicle to a stop when appropriate, and automatically (if within 3 seconds) accelerate back up to the original set speed. If the vehicle is stationary for over 3 seconds, SCC will prompt the driver to continue cruise conditions via the steering wheel switches.

Available on the Go with safety pack, Active X with safety pack, Elite, Special Edition & Highlander variants.
