White smoke will come out of a vehicle's exhaust system when the engine is cold. This is because of condensation build up in the engine and exhaust. The white smoke should go away after several minutes of idling. If you engine is always blowing white smoke, regardless of temperature, then it might be burning oil. Check the levels of your engine oil and your Transmission Fluid (if you have an automatic) and have the engine compression checked for blow-by.
