Transmission In order to prevent the engine from running at too low an RPM, which may cause it to stall, SelectShift will still automatically make some downshifts if it has determined that you have not downshifted in time. Although SelectShift will make some downshifts for you, it will still allow you to downshift at any time as long as the SelectShift determines that the engine will not be damaged from over-revving. SelectShift will not automatically upshift, even if the engine is approaching the RPM limit. It must be shifted manually by pressing the + button. Note: 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 WARNINGS Do not drive your vehicle until you verify that the brake lamps are working. 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. If the parking brake is fully released, but the brake warning lamp remains illuminated, the brakes may not be working properly. See your authorized dealer. Your vehicle is equipped with a brake-shift interlock feature that prevents the gearshift lever from being moved from P (Park) when the ignition is in the on position and the brake pedal is not pressed. If you cannot move the gearshift lever out of P (Park) position with the ignition in the on position and the brake pedal pressed, a malfunction may have occurred. It is possible that a fuse has blown or the vehicle's brake lamps are not operating properly. See Fuse Specification Chart (page 224). If the fuse is not blown and the brake lamps are working properly, the following procedure will allow you to move the gearshift lever from P (Park): 148 F150 (TF6)
