white smoke out of tailpipe
Some white smoke is normal especially in winter, but if it is a solid cloud of white and has a slight smell of coolant it is not normal, most likely indicates a blown head gasket or a cracked head, watch you cooling system, it could develop too much pressure and blow the radiator and or heater core, have it checked out as soon as possible, it could contaminate your engine oil very soon if not already.
Neons had lots of head gasket issues. Check the coolant level. Also pull the oil dipstick to see if it has any trace of coolant and milky white material indicating coolant in the oil. If the smoke is very white and dense I is most likely a head gasket that has failed.
