2007 Cadillac CTS-V Owner's Manual - Page 206

Oil Pressure Light {CAUTION: Do not keep driving if the oil pressure is low. If you do, your engine can become so hot that it catches fire. You or others could be burned. Check your oil as soon as possible and have your vehicle serviced. Notice: Lack of proper engine oil maintenance may damage the engine. The repairs would not be covered by your warranty. Always follow the maintenance schedule in this manual for changing engine oil. If your vehicle has this light, it will come on when there is a problem with your engine oil pressure. This light will come on when you turn your key to ON or START. It goes off once you start the engine. That is a check to be sure the light works. If it does not come on, be sure to have it fixed so it will be there to warn you if there is a problem. When the light comes on and stays on, it means that oil is not flowing through your engine properly. You could be low on oil and you might have some other system problem. See Engine Oil on page 346 for more information. 206
