Jack was going to the shopping centre with his mother. At the traffic lights he dashed across the road without waiting for his mother to cross. He was almost knocked down by a car.
His mother advised him, "Next time make sure there are no approaching vehicles before you cross the road."
Is 'next time' correctly used? I believe it should be "In future".

It looks fine to me.
next time when you cross the road make sure...
