If you do not move the shift lever forward or rearward, the vehicle will be in sport mode. When you are in the sport mode the vehicle will still shift automatically. While driving in sport mode, the transmission may remain in a gear longer than it would in normal driving mode based on braking, throttle input and vehicle lateral acceleration. 2. Press the shift lever forward to upshift or rearward to downshift. The DIC will show the requested gear range when moving the shift lever forward or rearward. See Driver Information Center (DIC) on page 3-73 for more information on the DIC. While using the DSC feature the vehicle will have firmer shifting and increased performance. You can use this for sport driving or when climbing/descending hills to stay in gear longer or to down shift for more power or engine braking. The transmission will only allow you to shift into gears appropriate for the vehicle speed and engine Revolutions Per Minute (RPM). The transmission will not automatically shift to the next higher gear if the engine rpm is too high. If shifting is prevented for any reason, the currently selected gear will flash multiple times in the DIC, indicating that the transmission has not shifted gears. The transmission will allow you to shift to the gear selected and will automatically downshift when the vehicle comes to a stop. This will allow for more power during take-off and passing. When accelerating your vehicle from a stop in snowy and icy conditions, you may want to shift into second gear. A higher gear allows you to gain more traction on slippery surfaces. 2-31
