Driver Shift Control (DSC) Notice: If you drive your vehicle at high RPMs without upshifting while using Driver Shift Control (DSC), you could damage your vehicle. Always upshift when necessary while using DSC. Your automatic transmission has a Driver Shift Control (DSC) feature that allows you to change gears similar to a manual transmission. To use the DSC feature: 1. Slide the shift lever over from DRIVE (D) to the right into the DSC area. When the transmission is in DSC mode the sport symbol in the Driver Information Center (DIC) will come on. 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 driver's selection when moving the shift lever forward or rearward. See Driver Information Center (DIC) on page 3-74 for more information on the DIC. When using the DSC mode, the number displayed on the Driver Information Center (DIC) indicates the gear that the transmission is in. When starting the vehicle from a stopped condition, only First (1) and Second (2) gear may be used. 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 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. 2-34
