Maintenance and Specifications Severe climates If you drive in extremely cold climates: • It may be necessary to increase the coolant concentration above 50%. • NEVER increase the coolant concentration above 60%. • A coolant concentration of 60% will provide improved freeze point protection. Increased engine coolant concentrations above 60% will decrease the overheat protection characteristics of the engine coolant and may cause engine damage. • If available, refer to the chart on the coolant container to ensure the coolant concentration in your vehicle will provide adequate freeze protection at the temperatures in which you drive in the winter months. If you drive in extremely hot climates: • It is still necessary to maintain the coolant concentration above 40%. • NEVER decrease the coolant concentration below 40%. • Decreased engine coolant concentrations below 40% will decrease the corrosion/freeze protection characteristics of the engine coolant and may cause engine damage. • If available, refer to the chart on the coolant container to ensure the coolant concentration in your vehicle will provide adequate protection at the temperatures in which you drive. Vehicles driven year-round in non-extreme climates should use a 50/50 mixture of engine coolant and distilled water for optimum cooling system and engine protection. Powertrain limiting and protection Note: Driving the vehicle without repairing the engine problem increases the chance of engine damage. Take your vehicle to an authorized dealer as soon as possible. The engine control module (ECU) is equipped with a feature called powertrain limiting and protection (PTLP). PTLP will help protect the engine from damage in case the engine is overheating (coolant and/or oil temperature too hot). PTLP will automatically intervene during normal engine operation should it determine the engine coolant and/or oil temperatures are too hot. It does this by gradually reducing the maximum allowable engine rpm until the engine has cooled sufficiently. 351 2012 Focus (foc) Owners Guide, 5th Printing USA (fus)
