Vehicle Care 10-19 Engine Overheating 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, a significant loss in power and engine performance will be noticed. The temperature gauge will indicate an overheat condition exists. Driving extended km (mi) 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, change the oil and reset the oil life system. See Engine Oil on page 10￿9. 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. Notice . When using concentrated washer fluid, follow the manufacturer instructions for adding water. 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. 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. Do not use engine coolant (antifreeze) in the windshield washer. It can damage the windshield washer system and paint. . 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. .
