Temporary Tap Manual Shift Mode
To enter Temporary Tap Shift Mode:
1. With the transmission 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.
2. To shift to the lowest available
gear, press and hold the left
control.
3. To deactivate, hold the right
control briefly. Automatic shifts
return after no manual shifts
have been done for seven to
10 seconds.
While using Tap Shift, the vehicle will
have firmer, quicker shifting. This can
be used 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
shifting into gears appropriate for the
vehicle speed and engine revolutions
per minute (rpm). If shifting is
prevented for any reason, a SHIFT
DENIED message will be displayed in
the instrument cluster. The
transmission will not automatically
shift to the next higher gear if the
engine rpm is too high. It will only
automatically shift to the next lower
gear if the engine rpm is much
too low.
