2007 Cadillac XLR Owner's Manual - Page 95

The Sport Automatic Mode is selected by moving the shift lever into the DSC area without shifting towards the +(plus) or − (minus) symbols. While in the Sport Automatic Mode, the transmission computer determines when the vehicle is being driven in a competitive manner. It then selects and holds the transmission in lower gears giving more noticeable upshifts for a sportier vehicle performance. Once you shift to the + (plus) or − (minus) controls, the driver manual gear selection is activated. A + (plus) symbol appears on the shift console above the DRIVE (D) indicator and minus symbol appears below the indicator. The Head-Up Display (HUD) also displays the requested gear, though the actual upshift or downshift could be delayed until the engine speed is correct for that gear. The requested gear displays on the HUD until the next time you upshift or downshift. The gear selected and shown in the HUD is one of a number of gears available. The vehicle does not upshift beyond the chosen gear. The actual gear that the vehicle shifts to depends on a combination of the driver-requested gear range, vehicle speed and throttle position. 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. If you do not upshift as the engine approaches the red line on the engine RPM (Revolutions Per Minute) gage, the engine speed is controlled to limit the engine RPM. 95
