8-8 Driving and Operating application. PMLF allows the transmission to hold the current gear instead of upshifting when the throttle is lifted. The DIC will indicate the requested gear range when moving the shift lever forward or rearward. While using DSC, the vehicle has firmer shifting and increased performance. This can be used for sport driving or when climbing or descending hills, to stay in gear longer, or to down shift for more power or engine braking. The transmission will only allow the driver to shift into gears appropriate for the vehicle speed and engine Revolutions Per Minute (RPM). The transmission will not automatically shift to the next lower gear if the engine RPM is too high. If shifting is prevented for any reason, the currently selected gear will flash multiple times, indicating that the transmission has not shifted gears. While in DSC, the transmission automatically downshifts when the vehicle comes to a stop. Sport Shift Mode The automatic transmission has a Sport Shift Mode. When you are in the Sport Shift Mode the vehicle will still shift automatically. The transmission may remain in a gear longer than it would in the normal driving mode based on braking, throttle input, and vehicle lateral acceleration. To use this feature, move the shift lever over from D (Drive) to the right quadrant. The Sport Shift message in the DIC displays. If the shift lever is not moved forward or rearward, the vehicle remains in sport mode. Performance Mode Lift Foot Mode Within Sport Shift Mode there is a further performance feature called Performance Mode Lift Foot (PMLF) Mode. The feature is activated automatically when sports oriented driving is detected, based on cornering and on/off throttle Driver Shift Control (DSC) Notice: If you drive your vehicle at high RPMs without upshifting while using DSC, you could damage the vehicle. Always upshift when necessary while using DSC. The automatic transmission has DSC that allows gear changes similar to a manual transmission. To use this feature: 1. Move the shift lever over from D (Drive) to the right quadrant. The Sport Shift message in the DIC displays. 2. To enter DSC, press the shift lever forward to upshift or rearward to downshift. The Active Select On message in the DIC will come on.
