Correct answer
- AUsando las rejillas de ventilación del salpicadero.Using the air vents on the dashboard.
To save fuel, it is more efficient to ventilate the vehicle using the air vents on the dashboard, because this way you use the vehicle's own ventilation system. Opening all the windows, or only the rear ones, can increase wind resistance, which can lead to higher fuel consumption, according to the Spanish traffic rules on vehicle energy efficiency.
