9-24 Driving and Operating
If equipped, the tap shift controls
are on the back of the steering
wheel. The tap shift controls can be
used in D (Drive), M (Manual Mode)
with Sport Mode automatic shift
active, or M (Manual Mode) with
Manual Shifting Mode.
To use the DSC feature using the
Tap Shift controls:
1. Move the shift lever to the right
from D (Drive) to M
(Manual Mode).
2. Tap the left control to downshift
and the right control to upshift.
3. To return to sport mode, hold the
right upshift control briefly,
or hold the gear shift lever
forward briefly, or return the shift
lever to D (Drive).
With the gear shift lever in D (Drive),
the tap shift controls will activate a
temporary tap manual shift mode,
allowing the transmission to be
manually shifted. Automatic shifts
return after no manual shifts have
been made for seven to
10 seconds. The temporary tap
mode can also be deactivated by
holding the right upshift control
briefly.
The tachometer display indicates
which gear the vehicle is in. The
number indicates the requested
gear range when moving the shift
lever forward or rearward.
CTS-V vehicles use tracer lights
around the outside of the
tachometer as a performance
upshift light. These tracers flash to
indicate when to shift to the next
higher gear to avoid the engine
speed limit. See Rev Counter on
page 5 14 for more information.
