Check engine and traction control light on 2002 saab 9-5

SOURCE: 2003 Saab 9-5 Check Engine Light

Take the car to Autozone, they will read the codes via OBD II for free.  Other parts stores may have the same policy ... call first.   My VW dealer charges $40 to pull the codes!!   I bought a low-end OBD II reader for $50, as the wife and I  both have VWs.

White smoke is usually antifreeze, the most frequent cause of this is head gasket blown or cracked head ... big bucks.  Hopefully this is not you.  Unless the car had a dramatic overheating incident, for most makes of cars, this should not happen until you have over 100K miles, probably closer to 200K.   
White smoke could also be break fluid sucked in from power brake booster.  If it's brake fluid, it will smell very bad.  
On cold days, when the car first starts, white smoke can just be normal condensation in the tailpipe ... if it happens after the car is warmed up ... it's something else.
Check your coolant overflow tank level ... if it's very low or empty ... put water in (don't bother with antifreeze yet in case you are burning it up in the engine).  
Good luck, ..ajm

SOURCE: Check Engine light and traction control light stay

there is nothing to do here but have the dealer run a scanner test to see what trouble codes were set with the lights coming on, until then there is no way to tell what the problem might be as there are over 200 possibilities.

Take the car to Autozone or similar business for a free code read with a scanner. Depending on what turns up, they will be happy to sell you any needed parts.
