198 Transmission Upshifts when accelerating Shift from: 15 mph 25 mph 40 mph 45 mph 50 mph Recommended shift speeds: 1 2 3 4 5 - - - - - 2 3 4 5 6 (24 (40 (64 (72 (80 km/h) km/h) km/h) km/h) km/h) In order to prevent the engine from running at too low an RPM, which may cause it to stall, the SST will still automatically make some downshifts if it has determined that you have not downshifted in time. 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.
