2014 Chevrolet Silverado 3500 HD Crew Cab Owner Manual - Page 303

Driving and Operating the plus/minus button located on the steering column lever is used to change to the gear. Grade Braking is not available when Range Selection Mode is active. See Tow/Haul Mode on page 9-37. While using Range Selection Mode, Cruise Control and the Tow/Haul Mode can be used. If the vehicle has an exhaust brake, it can also be used, but will not automatically downshift the transmission. See Exhaust Brake in the Duramax Diesel supplement. Notice: Spinning the tires or holding the vehicle in one place on a hill using only the accelerator pedal may damage the transmission. The repair will not be covered by the vehicle warranty. If you are stuck, do not spin the tires. When stopping on a hill, use the brakes to hold the vehicle in place. 9-37 Low Traction Mode If the vehicle has the Allison Transmission, a 4-Speed automatic transmission, or the Hydra-Matic 6-Speed Automatic Transmission with the 6.0L engine, it has a Low Traction Mode that assists in vehicle acceleration when road conditions are slippery, such as with ice or snow. While the vehicle is at a stop, select the second gear range using Range Selection Mode. This will limit torque to the wheels helping to prevent the tires from spinning. Tow/Haul Mode 4-Speed Automatic Transmission 6-Speed Automatic Transmission Vehicles with an automatic transmission have a Tow/Haul Mode. The Tow/Haul Mode adjusts the transmission shift pattern to reduce shift cycling, providing increased performance, vehicle control, and transmission cooling when driving down steep hills or Mountain grades, towing, or hauling heavy loads.
