Hyundai says the system "monitors the rear seats using an ultrasonic sensor that helps to detect the movements of children and pets." The system, Hyundai said, "first reminds drivers to check the rear seats when exiting the vehicle with a message on the center instrument cluster display. If the system detects movement in the rear seats after the driver leaves the vehicle it will honk the horn, flash the lights and send a Blue Link alert to the driver's smartphone via Hyundai's Blue Link connected car system."
U.S. Santa Fe sales were 133,171 units in 2017, a 1.5 percent gain from the previous year.
"Families are really going to like the thoughtful technologies found in the Santa Fe," said Brian Smith, COO of Hyundai Motor America, in a statement. "Forward Collision Avoidance Assist, Safe Exit Assist and Rear Occupant Alert are the result of a deep analysis of how families behave and can really help those sometimes dangerous situations. Easy-access rear seats, HTRAC AWD and a HeadsUp Display improve existing features with even more advanced technology."
