9-24 Driving and Operating
Vehicles with DSC may either use
the shift lever or the tap shift
controls on the back of the steering
wheel (if equipped) to manually shift
the automatic transmission.
To use DSC using the shift lever:
1. Move the gear 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. Move the shift lever forward to
upshift or rearward to downshift.
3. To cancel DSC, move the shift
lever back to D (Drive).
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 gear 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.
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
