its so when you turn off the ignition, the engine will run for 2.5 minutes after you take the key out. that way, the engine(particularly the turbo) can idle for a few minutes to cool down, essential if it was being driven hard. Otherwise, the oil in the turbo would stop circulating, be trapped in the hot turbo and burn, turning into some gunk not good for anything.
