Engine Coolant Temperature Gage This gage measures the temperature of the vehicle's engine. 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 needle moves into the shaded area, the engine is too hot. A temperature indicator light will turn on. If you have been operating your vehicle under normal driving conditions, and the temperature indicator light comes on, you should pull off the road, stop your vehicle and turn off the engine as soon as possible. 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 3-49 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 5-51 for more information. 3-33
