Driver Shift Control (DSC)
The Driver Shift Control (DSC) feature lets you manually
control the operation of the transmission.
To use this feature, move
the shift lever from the
D (Drive) position to the left
and into the driver shift
control gate.
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 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
D (Drive) 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 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.
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.

Not all manual downshift requests will be allowed by
the transmission. To prevent excessive engine RPMs,
each gear has a maximum vehicle speed associated
with it. Any downshift request above this speed is
not allowed by the transmission.
If shifting is prevented for any reason, the current
gear ashes multiple times in the Driver Information
Center (DIC), indicating that the transmission has
not shifted gears.
Some automatic downshifts can occur to maintain
minimum engine speed. This only happens if the vehicle
is left in too high of a gear for the vehicle’s speed.
For example, if you have been driving in sixth gear range
and come to a stop without manually downshifting, the
transmission automatically downshifts to rst gear and
displays rst gear on the HUD. As you begin to drive and
accelerate, the transmission remains in rst gear until the
driver selects an upshift.DSC can be used while using cruise control, but
transmission shifting is different while the cruise control
is on. This is not a malfunction and is necessary to
let proper operation of the cruise control.
To return to fully automatic operation, move the shift
lever to the right and back into D (Drive).
When accelerating the vehicle from a stop in snowy and
icy conditions, you may want to shift into second gear.
A higher gear allows you to gain more traction on slippery
surfaces.
In higher gears, on the XLR only, an automatic downshift
occurs if you press the accelerator pedal to the oor.
This feature provides adequate acceleration capabilities
if you forget to downshift manually. Tap the shifter
forward and the vehicle upshifts.
