What does the TC light mean on the vehicle? on 2003 Land Rover Discovery

Just bought the car and the light has only come on once but there was no manual in the vehicle for me to see what it means. Is this serious?

It means Traction Control and if one tire looses traction it will send power to the non spinning tire as to keep you from getting stuck
