Anytime your coolant level is below the fill line in the overflow bottle, top it off. Anytime the fluid changes color, gets foamy, or otherwise looks dirty; it is a good idea to change the fluid out. Dealer maintenance schedules do not list a Cooling System Flush as required maintenance until 150,000 miles.
