When towing a trailer:

• Turn off the speed control. The speed control may shut off automatically when you are towing on long, steep grades.
• It is recommended to select the “M” gear position when additional engine braking is needed. In situations such as prolonged downhill driving on steep grades (i.e., driving in mountainous areas), additional engine braking is needed to reduce the load on the vehicle’s regular brake system to prevent them from overheating. For more information on transmission operation and gear positions, see Automatic transmission operation in the Driving chapter.
• Allow more distance for stopping with a trailer attached; anticipate stops and brake gradually.
