Answers :

Hi, the message is telling you that your coolant level is low, so check the level and top it up to the maximum mark, if how ever its not low and it is up to the max then this would suggest the coolant level sensor is faulty, now the sensor is located on the coolant filler cap so if you look at the cap you should see a couple of wires going to it check these have not broke and have a look at the float on the inside of the coolant bottle to make sure thats not broke, the chances are this sensor will need replacing.

let me know if you need further assistance ok
