Additionally, regularly clean your air filter to ensure that the engine's recommended air-to-fuel ratio is retained.
Make sure your tires are properly inflated, according to the inflation specifications printed on the rear door sills of your X5. The inflation specs can vary depending on the laden weight of your vehicle.
