9-30 Driving and Operating
D (Drive):This position is for
normal driving. It provides the
best fuel economy. If more power
is needed for passing, and the
vehicle is:
.Going less than 56 km/h
(35 mph), push the accelerator
pedal about halfway down.
.Going about 56 km/h (35 mph) or
more, push the accelerator all
the way down.
Notice: If the vehicle seems to
accelerate slowly or not shift
gears when you go faster, and
you continue to drive the vehicle
that way, you could damage the
transmission. Have the vehicle
serviced right away. You can
drive in L (Low) when you are
driving less than 56 km/h (35 mph)
and D (Drive) for higher speeds
until then.
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 9‑30 for more information.
Manual Mode
Driver Shift Control (DSC)
Notice:If you drive the vehicle
at a high rpm 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 5‑25. When you are in
Sport Mode, the vehicle will still shift automatically, but
chassis tuning is modified.
See
Selective Ride Control on
page 9‑38. 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

9-38 Driving and Operating
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
guntil the StabiliTrak
Off light comes on the instrument
panel. For information on turning
TCS off and on, see Traction
Control System (TCS) on
page 9‑36.

StabiliTrak activates, the cruise
control automatically disengages.
Press the cruise control button to
reengage when road conditions
allow. See Cruise Control on
page 9‑39 for more information.
Limited-Slip Differential
Vehicles with a limited-slip
differential can give more traction
on snow, mud, ice, sand, or gravel.
It works like a standard differential
most of the time, but when traction
is low, this feature allows the drive
wheel with the most traction to
move the vehicle.
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).
TOUR:
Use for normal city and
highway driving. This setting
provides a smooth, soft ride.
SPORT: Use where road conditions
or personal preference demand
more control. This setting provides
more “feel,” or response to road
conditions through increased
steering effort and suspension
tuning.
The setting can be changed at any
time. Based on road conditions,
steering wheel angle, and vehicle
speed, the system automatically
adjusts to provide the best handling
while providing a smooth ride.
The TOUR and SPORT modes
will feel similar on a smooth road.
