Correct answer
There is low pressure in the circuit.
It warns of insufficient lubrication pressure, although the warning system itself could also be faulty. Stop as soon as safely possible and switch off the engine to prevent damage. Do not continue merely because the level appears correct: low pressure and low level are different indications. Follow manufacturer checks and seek assistance if unresolved; do not keep the engine running to investigate.
