Engine Coolant Temperature Gage This gage shows the engine coolant temperature. Tire Pressure Light For vehicles with a tire pressure monitoring system, this light comes on briefly when the engine is started. It provides information about tire pressures and the Tire Pressure Monitoring System. When the Light is On Steady If the indicator on the gage moves towards the shaded area on the thermostat, it means that the engine coolant has overheated. If the vehicle has been operating under normal driving conditions, pull off the road, stop the vehicle and turn off the engine as soon as possible. See Engine Overheating on page 6-30. This indicates that one or more of the tires is significantly underinflated. A tire pressure message in the Driver Information Center (DIC), can accompany the light. See DIC Warnings and Messages on page 3-56 for more information. Stop and check the tires as soon as it is safe to do so. If a tire is underinflated, inflate to the proper pressure. See Tires on page 6-56 for more information. 3-41
