190 UNDERSTANDING YOUR INSTRUMENT PANEL 9. Oil Pressure Gauge - Premium Cluster Only The pointer should always indicate some oil pressure when the engine is running. A continuous high or low reading, under normal driving conditions, may indicate a lubrication system malfunction. Immediate service should be obtained from an authorized dealer. NOTE: If the gauge pointer moves to either extreme of the gauge, the "Check Gauges" indicator will illuminate and a single chime will sound. 10. Transfer Case Position This display indicator shows the transfer case position selection. For additional information refer to "4-Wheel Drive Operation" in section 5 of this manual. 11. TOW HAUL The TOW HAUL button is located at the end of the gear shift lever. This light will illuminate when the TOW HAUL OD/OFF button is pushed once. 12. OD/OFF The OD/OFF button is located at the end of the gear shift lever. This light will illuminate when the TOW HAUL OD/OFF button is pushed twice. 13. Temperature Gauge The temperature gauge shows engine coolant temperature. Any reading within the normal range indicates that the engine cooling system is operating satisfactorily. The gauge pointer will likely indicate a higher temperature when driving in hot weather, up mountain grades, or when towing a trailer. It should not be allowed to exceed the upper limits of the normal operating range.
