Show answer

Correct answer

  • AMantener de forma constante la velocidad elegida por el conductor.To keep the speed chosen by the driver constant.
Explanation

Adaptive cruise control keeps the speed chosen by the driver constant and, using a front radar, reduces it if it catches up with another vehicle, to keep a safe distance. It does not set the speed shown on signs by itself, and it does not speed up because the driver is going slowly.
