Driving and Operating 8-29
Manual Mode:This position is
shown on the shifter as a +/−.
It allows the driver to select the
gears appropriate for current driving
conditions. See Manual Mode
on
page 8‑29for more information.
Manual Mode
Driver Shift Control (DSC)
Notice: If you drive the vehicle at
high RPMs without upshifting
while using Driver Shift Control
(DSC), you could damage the
vehicle. Always upshift when
necessary while using DSC. Driver Shift Control (DSC) allows
you to shift an automatic
transmission similar to a manual
transmission. To use the DSC
feature:
With Selective Ride Control
1. Move the shift lever to the left
from D (Drive).
The vehicle will be in Sport
Mode. The gear indicator in the
DIC will still display a D for
Drive, and the Sport Mode On
message will be displayed
momentarily. See Driver
Information Center (DIC)
on
page 4‑25. When you are in
Sport Mode, the vehicle will still
shift automatically, but chassis
tuning is modified. See Selective
Ride Control
on page 8‑36. If you move the shift lever
forward or rearward, the
transmission will enter Manual
Mode, and the DIC gear
indicator will change to an M
followed by a number
representing the gear the vehicle
is currently in.
2. In Manual Mode, press the shift lever forward to upshift or
rearward to downshift.
Without Selective Ride Control
1. Move the shift lever to the left from D (Drive).
The transmission will enter
Manual Mode. The DIC gear
indicator will change to an M
followed by a number
representing the gear the vehicle
is currently in.
2. In Manual Mode, press the shift lever forward to upshift or
rearward to downshift.

8-36 Driving and Operating
This also occurs when traction
control is activated. A noise might
be heard or vibration might be felt in
the brake pedal. This is normal.
Continue to steer the vehicle in the
intended direction.
If there is a problem detected with
StabiliTrak, the TCS/StabiliTrak light
comes on and the system is not
operational. SeeElectronic Stability
Control (ESC)/Traction Control
System (TCS) Indicator/Warning
Light
on page 4‑22. Driving should
be adjusted accordingly.
StabiliTrak comes on automatically
whenever the vehicle is started. To
assist with directional control of the
vehicle, the system should always
be left on.
StabiliTrak can be turned off if
needed by pressing and holding
g
until the StabiliTrak Off light comes
on the instrument panel. For
information on turning TCS off and
on, see Traction Control System
(TCS) in this section.
If cruise control is being used when
StabiliTrak activates, the cruise
control automatically disengages.
Press the cruise control button to
reengage when road conditions
allow. See Cruise Control
on
page 8‑37for more information.
Selective Ride Control
The vehicle may have a ride control
system called Selective Ride
Control. The system provides the
following performance benefits:
.Reduced Impact Harshness
.Improved Road Isolation
.Improved High-Speed Stability
.Improved Handling Response
.Better Control of Body Ride
Motions
To switch from TOUR to SPORT
mode, move the shift lever to
the left while the transmission is
in D (Drive).
