See StabiliTrak® System on page 4-6, Traction Control System (TCS) on page 4-8 and DIC Warnings and Messages on page 3-38 for more information. Tire Pressure Light For vehicles with a tire pressure light, this light comes on briefly when the engine is started and provides information about tire pressures and the Tire Pressure Monitoring System. Engine Coolant Temperature Gage This gage shows the engine coolant temperature. When the Light is On Steady 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 3-38 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 5-54 for more information. If the gage pointer is near the top of the gage, the engine is too hot. It means that the engine coolant has overheated. If the vehicle has been operating under normal driving conditions, pull the vehicle off the road, stop the vehicle and turn off the engine as soon as possible. See Engine Overheating on page 5-32 for more information. When the Light Flashes First and Then is On Steady This indicates that there could be a problem with the Tire Pressure Monitor System. The light flashes for about a minute and stays on steady for the remainder of the ignition cycle. This sequence repeats with every ignition cycle. See Tire Pressure Monitor System on page 5-63 for more information. 3-29
