2003 Accent smoke?

Could be many things. Did you have an oil changed or add oil? If it drips on a hot manifold or exhaust pipe it can smoke. Same with an oil leak. Check the coolant level too. Did you notice the gauge?

Sometimes a slipping belt will smoke a bit before it fails.

Brake pads sticking can also smoke as they overheat.

Since it was on the passenger side, did you have a passenger? If so, did he/she eat pickled eggs and beer?

Wholey irrelevant Edwin. The OP made no reference to green smoke, which is often the mistaken reference for the highly acclaimed green cloud that accompanies a good night of pickled eggs and beer. Please try to focus on these things...

Last oil change was 2.5 months ago, it's almost time for another one. I didn't hear any best slipping, but I'm gonna get in there with a flashlight in a bit and check for any obvious damage. What's the best way to find out if the brake pads are sticking?

If the pads were smoking, chances are you's smell it around the wheel.

OK, but how about sauerkraut? Did his eyes burn?

Found out what the problem was... The oil sending unit was bad/leaking. Dealer replaced it under warrenty. Oil was dripping onto the exhaust manifold, and thus making some pretty white smoke. All fixed now!
