Oil Pressure Light This light comes on briefly while starting the engine. If it does not, have the vehicle serviced by your dealer/ retailer. If the system is working normally the indicator light then goes off. If 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. Security Light { CAUTION: Do not keep driving if the oil pressure is low. The engine can become so hot that it catches fire. Someone could be burned. Check the oil as soon as possible and have the vehicle serviced.

Always follow the maintenance schedule in this manual for changing engine oil. For information regarding this light and the vehicle's security system, see Content Theft-Deterrent on page 2-16. 3-39
