Instruments and Controls appear in the Driver Information Center (DIC). See Engine Oil Messages on page 5‑36 and Engine Oil on page 10‑8 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. 5-13 Engine Coolant Temperature Gauge English Metric This gauge shows the engine coolant temperature. It also provides an indicator of how hard the vehicle is working. During a majority of the operation, the gauge will read 100°C (210°F) or less. If the vehicle is pulling a load or going up hills, it is normal for the temperature to fluctuate and approach the 122°C (250°F) mark.
