Correct answer

  • ANo; su función es avisar al conductor de una posible colisión.No. Its job is to warn the driver of a possible collision.
Explanation

The main job of the forward collision warning (FCW) system is to alert the driver when it detects a risk of collision with the vehicle in front. It does not brake by itself. It gives visual and/or sound warnings so that the driver reacts in time and brakes if necessary. The system that brakes automatically is autonomous emergency braking (AEB or AEBS). It detects a possible impact and, if the driver does not react in time, applies the brakes automatically to avoid the collision or make it less serious. FCW only warns of the danger; AEB/AEBS can step in and brake the vehicle.
