The coolant level sensor in the coolnat reservior is shorted out . The coolant level when driving is circulating fine . The coolant must be going just past the sensor and triggering it off.

The alternator is most likely the problem, it isn't putting out enough of amps to charge the battery, but enough to keep it going which won't last long. Before assuming the battery or alternator, try your battery connections for corrosion or tightness. If you live close to an auto parts store they can check the battery and alternator to see which is the problem. The battery will not hold up long if running lights at night or other power consuming things.

On the Owner's Manual there's a procedure you have to follow to bleed the air in the cooling system, until you bleed the system for air, the low coolant light will come on every time.

The process is rather simple and quick, all you need is a flat head screw driver.

DO NOT OPEN THE COOLING SYSTEM WHEN HOT.

Good Luck!! Don't forget to rate this post!!

The coolant level sensor is inside the coolant bottle. It is not replaceable separately. You will have to replace the reservoir to replace the sensor.
