trac off light for 2004 buick century

What is your question?

It would come on only on occasion but now comes on about every time I start out driving within past couple of days along with service vehicle soon light. The abs light and service engine light have appeared for several months with no problems in performance of vehicle and mechanic told me to not worry about it. Its the weekend now and I won't be able to see my mechanic until tomorrow (Monday). Its the trac off light that concerns me.

What makes this problem better or worse?
