Driver Shift Control (DSC) Notice: If you drive the vehicle at high RPMs without upshifting while using Driver Shift Control (DSC), you could damage the vehicle. Always upshift when necessary while using DSC. Driver Shift Control (DSC) allows you shift an automatic transmission similar to a manual transmission. To use the DSC feature: 1. Move the shift lever to the right from D (Drive) into the DSC area. When in DSC mode, the sport symbol will appear in the Driver Information Center (DIC). 2. Press the shift lever forward to upshift or rearward to downshift. When using the DSC mode, the number displayed on the Driver Information Center (DIC) indicates the gear that the transmission is in. See Driver Information Center (DIC) on page 3-72 for more information on the DIC. When starting the vehicle from a stopped condition, only 1 (First) and 2 (Second) gear may be used. 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 vehicle will remain in sport mode if the shift lever is not moved. Sport mode will shift automatically but remain in a gear longer then it would in normal driving mode based on braking and acceleration. 2-32 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.
