Oil Pressure Light The light will come on when you turn your key to ON or START. {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. It goes off once you start your 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 something goes wrong. When the light comes on and stays on, it means that oil is not flowing through the engine properly. The vehicle could be low on oil and it might have some other system problem. See Engine Oil on page 323 and "OIL" under DIC Warnings and Messages on page 196 for more information. 189
