WARNING   WARNING:  Do not use diesel engine exhaust braking when the road surface is slippery. Failure to follow this instruction could result in the loss of control of your vehicle.

Tow/haul delays upshifts to reduce the frequency of transmission shifting.
Tow/haul provides engine braking in all forward gears, which slows your vehicle and assists you in controlling your vehicle when descending a slope.
Tow/haul improves transmission operation when towing a trailer or a heavy load.
Depending on driving conditions and load conditions, tow/haul may downshift the transmission, slow your vehicle and control your vehicle speed when descending a hill, without pressing the accelerator pedal. The amount of downshift braking provided varies based upon the amount the brake pedal is pressed.
