Your Buick Lucerne is equipped with a tire pressure monitor system. This system notifies you if the tire pressure is too low. When you get the Service Tire Monitor warning, it indicates that there is a problem with the tire monitoring system itself. Id does not mean that the tire pressure is (necessarily) too low.
If you do get this warning message, the first thing you should do is check the actual tire pressure. This message can occur when the tire pressure is extremely low, or extremely high.
Once you confirm that the tire pressure is normal (you can look on the inside of the driver’s door jam to see what the tire pressure should be), it is safe to drive the vehicle as though you don’t have a tire pressure monitoring system. But, you will need to check the tire pressure regularly until the system has been repaired.
