When engine is cold remove radiator cap and make sure the coolant is full.
If so, then the low coolant sensor may be bad. The temp. Gauge sender may also be bad. Check all fuses first and make sure the coolant is full.
You may be better of having the cooling system flushed and fresh coolant added.
If equipped with Dex-Cool, it may have sludged up and caused a blockage or the sensors to not read correctly.
