Correct answer

  • CRealiza una corrección en la dirección o en los frenos para que el vehículo retorne hacia el centro del carril.It corrects the steering or applies the brakes so that the vehicle returns towards the centre of the lane.
Explanation

If the driver does not respond to the warning, the lane keeping assist (LKA or LKS) corrects the steering or brakes one of the wheels to bring the vehicle back to the centre of the lane. A simple lane departure warning (LDW) only warns. Neither of them acts if you use the indicator or steer decisively.
