What must you do if the oil pressure warning light fails to switch off after starting the engine?

If the oil pressure warning light does not switch off after starting the engine, it indicates a potential problem with the oil pressure, which could lead to severe engine damage if not addressed.

The correct actions are to shut down the engine immediately and check the engine oil level. This is crucial because continuing to drive with low oil pressure can cause the engine to overheat or seize, leading to costly repairs. In accordance with German traffic regulations, proper vehicle maintenance and the immediate rectification of warning signals are required to ensure the safety of the vehicle and its occupants.

Always prioritizing the engine's health by taking the right precautions helps maintain road safety and comply with legal obligations regarding vehicle operation.
