5-14 Instruments and Controls Center (DIC). See Engine Oil Messages on page 5‑38 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. Notice: 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. If the vehicle is a hybrid, see the hybrid supplement for more information. Engine Coolant Temperature Gauge 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). 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 Metric
