With a 40 point advantage in the Drivers' Championship battle and 37 in the Constructors' standings heading into the final six races of the season, it would be all to easy to think the battle has been won. But neither Toto nor the team are taking anything for granted.
"There's marginal gains that will determine the outcome of this Championship, because on performance levels we are very close to each other," he continued.
"So, we have to keep the foot on the throttle and try to avoid mistakes and continue to develop the car.
"40 points advantage or zero, it makes no difference for us. It's six weekends to go. You can see, like in Austria where we had a double DNF, how quickly it goes and you lose 25 points.
"Insofar, we just have to look weekend by weekend and try to perform at our best level. It's only won when it's won."
