Depending on the temperature outside, but when its cold in particular whenever standstill in traffic i can see smoke from my mirrors, Is this normal? it stops as soon as i start moving again. And sometimes when starting the car on a very cold mornings and letting it warm up on idle, a huge amount of smoke is usually coming out of the exhaust which soon disappears. The exhaust smoke doesnt smell or anything except sometimes if car has been sitting for a long time then the first few minutes it would smell

White smoke coming from your exhaust is fine, its just condensation evaporating.

However, if your smoke is colored then you have a problem. Blue smoke means your car is burning oil and black smoke means your burning fuel.

White Smoke that disappears after a seconds or so is fine, its just condensation in the exhaust. White smoke that STAYS is what you really have to worry about, could mean coolant leak thats burning
