Cadillac 2007 XLR - 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.
