Default Steam or Smoke from exhaust

I just got my 08 is250 2 weeks ago. I noticed there's a lot of steam/smoke that comes out when it first starts. Even after it warms up it seems has some steam or smoke come on the back. I put my finger on the exhaust and it had some moisture around the time. I haven't noticed any antifreeze leaking or anything but i was wondering is it normal for all the is to steam like this. I just had the car at the dealer and it checked out fine never has overheated since i had it nor never used antifrieeze but seems unusual. All lexus IS like this?

What color is the smoke coming out of the tailpipe? Also, you mentioned that it also looked like steam. Not to sound demeaning, but are you referring to seeing your exhaust gasses when it's cold outside?

The smokes or steam is white. Even when it's warmed up you still see a little bit of it. I mean i haven't owned the car but two weeks and it's been cold but i did notice some white smoke. I haven't seen any leaks around the engine nor have i noticed the coolant resavoir going low. I been keeping an eye on it but it may just be steam. Like i said im new to the car.

Pretty sure it's just cause it's cold out.

I figured so, is the 2.5 a pretty reliable engine?

That steam is normal. Sometimes more on one side also.
