Any white mayonnaise looking substance on the oil filler cap?
Is the coolant plastic tank translucent white or a dirty brown colour inside it?
Is there any oily substance floating on top of the water?
It is likely that it is just condensation in the exhaust turning to steam as the exhaust gets hot but it could be early signs of a head gasket failure.
As davealfa says also keep an eye on the oil and water levels but note that these engines can use quite a lot of oil even when nothing is wrong.
Please do note my comment that these engines can use oil and they do NOT have a low oil level warning light so you can be running with little or no oil and not know it until your engine is trashed. Check the oil level now and top it up if needed, then check it every second tank of fuel as it is better safe than sorry and you will then know if you have one that does use oil (some do, some don't.)
