Engine Overheating You will find a coolant temperature gage on your vehicle's instrument panel cluster. See Engine Coolant Temperature Gage on page 3-40. In addition, you will find an ENGINE COOLANT HOT, ENGINE OVERHEATED and a REDUCED ENGINE POWER message in the DIC on the instrument panel. See Driver Information Center (DIC) on page 3-46. Notice: After driving in the overheated engine protection operating mode, to avoid engine damage, allow the engine to cool before attempting any repair. The engine oil will be severely degraded. Repair the cause of coolant loss and change the oil. See Engine Oil on page 5-11. Overheated Engine Protection Operating Mode If an overheated engine condition exists and the REDUCED ENGINE POWER message is displayed, an overheat protection mode which alternates firing groups of cylinders helps prevent engine damage. In this mode, you will notice a loss in power and engine performance. This operating mode allows your vehicle to be driven to a safe place in an emergency. Driving extended miles (km) and/or towing a trailer in the overheat protection mode should be avoided. 5-25
