The coffee cup icon displayed on a car's dashboard is typically a fatigue driving warning indicator. When the vehicle speed ranges between 80 and 180 kilometres per hour, the system monitors the driver's condition through predefined algorithms. Upon detecting fatigue risk, it activates an audible alert, steering wheel vibration, and flashing icon to prompt the driver to take timely breaks for road safety. Additionally, certain models may utilize this icon to denote engine cold-start preheating status (briefly displayed during initial startup when coolant temperature is suboptimal) or air recirculation mode, though specific interpretations should be verified against the vehicle's manual. Should the icon remain illuminated alongside other anomalies (e.g., coolant temperature warning), immediate inspection of the cooling system or consultation with an authorised service centre is advised. Regular familiarization with instrument cluster symbols-including common warnings like ABS and tyre pressure indicators-enables prompt recognition of vehicle status and appropriate response measures.
