Technically you are supposed to replace the timing belt or chain every 60,000 miles. It is a costly expense to replace it so often but it can be far more costly if you don't. Since your vehicle has a chain the pieces can wear down and eventually break and shoot up into your engine causing catastrophic engine failure which can completely ruin your vehicle.

The Pontiac Grand Prix has a Timing Chain with a spring loaded tensioner. The tensioner is know to wear, crack and then break. The timing chain and tensioner should be replaced at 100,000 miles. This is a pretty big job that can be done with the motor in the car. $$$ Ray
There is no maintenance schedule for replacing a timing chain. Timing chains are designed to last the life of the engine and are normally replaced during a complete engine rebuild.
