Instruments and Controls Oil pressure may vary with engine speed, outside temperature and oil viscosity, but readings above the low pressure zone indicate the normal operating range. When the oil pressure reaches the low pressure zone, the OIL PRESSURE LOW STOP ENGINE message appears in the Driver Information Center (DIC). See Engine Oil Messages on page 5‑41 and Engine Oil on page 10‑7 for more information. A reading in the low pressure zone may be caused by a dangerously low oil level or some other problem causing low oil pressure. Check the oil as soon as possible. 5-15 { WARNING 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. Notice: Lack of proper engine oil maintenance can damage the engine. The repairs would not be covered by the vehicle warranty. Always follow the maintenance schedule for changing engine oil. If the vehicle is a hybrid, see the hybrid supplement for more information. English The oil pressure gauge shows the engine oil pressure in psi (pounds per square inch) when the engine is running. Canadian vehicles indicate pressure in kPa (kilopascals).
