10-24 Vehicle Care Overheated Engine Protection Operating Mode This emergency operating mode allows the vehicle to be driven to a safe place in an emergency situation. If an overheated engine condition exists, an overheat protection mode which alternates firing groups of cylinders helps prevent engine damage. In this mode, there is significant loss in power and engine performance. The engine coolant temperature gauge indicates if an overheat condition exists. Driving extended distances and/or towing a trailer in the overheat protection mode should be avoided. Washer Fluid What to Use When windshield washer fluid is needed, be sure to read the manufacturer's instructions before use. If operating the vehicle in an area where the temperature may fall below freezing, use a fluid that has sufficient protection against freezing. . { Caution Do not use engine coolant (antifreeze) in the windshield washer. It can damage the windshield washer system and paint. Do not mix water with ready-to-use washer fluid. Water can cause the solution to freeze and damage the washer fluid tank and other parts of the washer system. When using concentrated washer fluid, follow the manufacturer instructions for adding water. Fill the washer fluid tank only three-quarters full when it is very cold. This allows for fluid expansion if freezing occurs, which could damage the tank if it is completely full. . Adding Washer Fluid . . Open the cap with the washer symbol on it. Add washer fluid until the tank is full. See Engine Compartment Overview on page 10-6 for reservoir location.
