FORD 2013 F-150 v.1 - Manual (Page 207)

Although the SST will make some downshifts for you, it will still allow
you to downshift at any time as long as the SST determines that the
engine will not be damaged from over-revving.
The SST will not automatically upshift, even if the engine is approaching
the RPM limit. It must be shifted manually by pressing the + button.
Engine damage may occur if excessive engine revving is held without
shifting.
PRS (Progressive Range Selection)
With the gearshift lever in D (Drive), press the – button to active PRS.
The available and selected gears will be indicated on the instrument
cluster.
All available gears will be displayed with the current gear indicated.
Press the – button again to lock out gears beginning with the highest
gear. Example: press the – button twice to lock out 6th and 5th gears.
Only the available gears will be displayed and the transmission will
automatically shift between the available gears. Press the + button to
unlock gears to allow the transmission to shift to higher gears. The
transmission will shift automatically within the gear range you select.
Automatic Transmission Adaptive Learning
This feature is designed to increase durability and provide consistent
shift feel over the life of the vehicle. A new vehicle or transmission may
have firm shifts, soft shifts or both. This operation is considered normal
and will not affect function or durability of the transmission. Over time,
the adaptive learning process will fully update transmission operation.
Additionally, whenever the battery is disconnected or a new battery
installed, the strategy must be relearned.
Brake-shift interlock
WARNING: Do not drive your vehicle until you verify that the
brake lamps are working.
WARNING: When doing this procedure, you will be taking the
vehicle out of park which means the vehicle can roll freely. To
avoid unwanted vehicle movement, always fully set the parking brake
prior to doing this procedure. Use wheel chocks if appropriate.
