234 DRIVING AND OPERATING
Tap Shift
If equipped, the tap shift controls are
on the back of the steering wheel.
To use DSC using the tap shift
controls:
1. Move the shift lever to the left
from D (Drive) to M (Manual
Mode). The transmission will be
in Manual Mode and will hold
the current gear.
2. Pull the control toward you to
shift. Pull the left control to
( ) downshift, and the right
control to (+) upshift. To shift to
the lowest available gear, press
and hold the left control ( ).
3. To cancel DSC, move the shift
lever back to D (Drive).
Tap Shift Mode can also be used
temporarily while driving in D (Drive).
Pull either the (+) upshift or
( ) downshift control.
To cancel Tap Shift Mode, hold
the (+) upshift control for two seconds.
If no action is taken, the vehicle
returns to automatic shifting after a
brief period of driving at a steady
speed, or when the vehicle comes to
a stop.
While using the DSC feature, the
vehicle will have firmer, quicker
shifting. This can be used for sport
driving, climbing or descending hills,
staying in gear longer, downshifting
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). The transmission
will not automatically shift to the next
higher gear if the engine rpm is
too high.
If shifting is prevented for any reason,
a DIC message will appear. 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,
or third gear as available. A higher
gear allows the vehicle to gain more
traction on slippery surfaces. See
Driver Mode Control 0 243.
