All-Wheel Drive; Drive Systems - Cadillac CTS Owner's Manual

With the shift lever in D (Drive) and
not in Permanent Tap Shift Mode,
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 done for seven to 10 seconds.
The Temporary Tap Shift Mode can
also be deactivated by holding the
right upshift control briefly.
While using Tap Shift, the vehicle
will have firmer, quicker shifting. You
can use this for sport driving or
when climbing or descending hills,
to stay in gear longer or to downshift
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 or to the next
higher gear when the maximum
engine rpm is reached.
If shifting is prevented for any
reason, a SHIFT DENIED message
will be displayed in the instrument
cluster. See Transmission
Messages 0 145.
When accelerating the vehicle from
a stop in snowy and icy conditions,
it is suggested to shift into second
gear. A higher gear allows the
vehicle to gain more traction on
slippery surfaces.
Shift Indicator
The shift indicator illuminates in the
instrument cluster when a gear shift
is recommended for best fuel
economy. When the arrow is pointed
up, an upshift is recommended.
When the arrow is pointed down, a
downshift is recommended. The
number displayed with the arrow
indicates the recommended gear.
