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 AUTOMATIC OVERDRIVE (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. 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. 2-34
