Overheated Engine Protection Operating Mode This operating mode allows your vehicle to be driven to a safe place in an emergency. Should an hot engine condition exist, an overheat protection mode which alternates firing groups of cylinders helps prevent engine damage. In this mode, there is a loss in power and engine performance. Driving extended miles (km) and/or towing a trailer in the overheat protection mode should be avoided. 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 360.
