GMC Terrain: Warning Lights, Gauges, and Indicators / Engine Oil Pressure Light
Caution
Lack of proper engine oil maintenance can damage the engine. Driving with the engine oil low can also damage the engine. The repairs would not be covered by the vehicle warranty. Check the oil level as soon as possible. Add oil if required, but if the oil level is within the operating range and the oil pressure is still low, have the vehicle serviced. Always follow the maintenance schedule for changing engine oil.
This light should come on briefly as the engine is started. If it does not come on, have the vehicle serviced by your dealer.
