Driving and Operating 203
To enter Permanent Tap Shift Mode:
1. Move the shift lever from
D (Drive) to M (Manual Mode).
While in Tap Shift Mode, the M
of the PRNDM section of the
instrument cluster will become
highlighted, and the current
gear is indicated.
2. Tap the left control toward the
driver to downshift, and the
right control toward the driver
to upshift. To shift to the lowest
available gear, press and hold
the left control.
3. To exit, move the shift lever
back to D (Drive).
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. The vehicle exits
Temporary Tap Shift Mode after the
accelerator pedal is steady for
six seconds. Temporary Tap Shift
Mode holds a gear longer without
exiting when coasting, to provide
powertrain braking. 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 downshift if the
engine rpm is too high in the next
lower gear, or upshift 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 0 149.
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.
