Driver Shift Control (DSC)
The Driver Shift Control (DSC) feature lets you manually
control over the operation of the transmission.
XLR
The DSC mode is selected by moving the shift lever
into the DSC area, which activates the driver manual
gear selection. To request an upshift in DSC, briefly
move the shift lever up toward the plus (+) symbol.
To request a downshift, briefly move the shift lever
down toward the minus (−) symbol. A plus (+)
symbol will appear on the shift console above the
AUTOMATIC OVERDRIVE (D) indicator and
minus symbol will appear below the indicator.
To use this feature,
move the shift lever
from the AUTOMATIC
OVERDRIVE (D) position
to the left and into the
driver shift control gate.
The Head-Up Display (HUD) will also display the
change in gear, though the actual upshift or downshift
may be delayed until the engine speed is correct for that
gear. The 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.
It does not mean that the vehicle will operate only in
that specific gear. The actual gear that the vehicle shifts
to depends on a combination of the driver-requested
gear range, vehicle speed and throttle position.

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 will then select and hold the
transmission in lower gears and have more noticeable
upshifts for a sportier vehicle performance until you
use the plus (+) or minus (−) controls, which activates
the driver manual gear selection. A plus (+) symbol
will appear on the shift console above the AUTOMATIC
OVERDRIVE (D) indicator and minus symbol will
appear below the indicator. The Head-Up Display (HUD)
will also display the change in gear, though the actual
upshift or downshift may be delayed until the engine
speed is correct for that gear.
