Tap Shift
To use Tap Shift, the shift lever must be in Manual
Mode. Vehicles with this feature have switches on
the back of the steering wheel. Tap the left switch to
downshift, and the right switch to upshift.
The tachometer display on the instrument panel cluster
will show which gear the vehicle is in and a number
indicating the requested gear range when moving
the shift lever forward or rearward. See Speedometer
and Odometer on page 3-33 for more information on
the odometer.
CTS-V vehicles use tracer lights around the outside
of the tachometer as a performance up-shift light.
These tracers flash to indicate when to shift to the
next higher gear to avoid the engine speed limit.
See Tachometer on page 3-33 for more information.
While using the Tap Shift feature, the vehicle will have
firmer, quicker shifting for increased performance.
You can use this for sport driving or when climbing or
descending hills, to stay in gear longer, or to down shift
for more power or engine braking.
The transmission will only allow you to shift into
gears appropriate for the vehicle speed and engine
Revolutions Per Minute (RPM). The transmission will
not automatically shift to the next lower gear if the
engine RPM is too high, nor to the next higher gear
when the maximum engine RPM is reached.
If shifting is prevented for any reason, the currently
selected gear will flash multiple times, indicating that
the transmission has not shifted gears.
While in the Tap Shift mode, the transmission will not
automatically downshift on hard acceleration.
When accelerating your vehicle from a stop in snowy
and icy conditions, you may want to shift into second
gear. A higher gear ratio allows you to gain more traction
on slippery surfaces.
