204 DRIVING AND OPERATING
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 manual Tap 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 0 151.
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 slipper y
surfaces.
