The speed control may shut off automatically when you are towing on long, steep grades. • Consider turning overdrive off (4-speed transmissions) or using the tow/haul feature (6-speed transmissions) to help eliminate excessive shifting and aid in transmission cooling. Refer to Automatic transmission operation in the Driving chapter. • Allow more distance for stopping with a trailer attached; anticipate stops and brake gradually. • Do not exceed the GCWR rating or transmission damage may occur. 267
