Driver Shift Control (DSC)
The vehicle has Driver Shift Control (DSC). DSC
controls the transmission and vehicle speed while driving
down hill or towing a trailer by allowing you to select
a desired range of gears.
To use this feature:
1. Move the shift lever to the M (Manual Mode).
This will force a downshift from the current gear,
for gears 3 through 6.
2. Press the (+) plus or (−) minus button on the left
side of the steering wheel, to select the desired
range of gears for current driving conditions.When in the M (Manual Mode) a number will display
next to the M, indicating the maximum available gear.
The DIC display will show the message MANUAL SHIFT
on the rst line and the maximum available gear will be
displayed on the second line. SeeDriver Information
Center (DIC) on page 3-46andDIC Operation and
Displays (Using DIC Buttons) on page 3-47orDIC
Operation and Displays (Using Trip Odometer Reset
Stem) on page 3-52for more information. The number
displayed in the DIC is the highest gear available.
The transmission will be limited to the gear selected and
lower gears. Shifting will occur normally while driving,
however the cluster will continue to display the maximum
available gear. Higher gears will not be available unless
the selection is changed to include higher gears using
the (+) plus button.
Grade Braking is not available when the Driver Shift
Control is active. SeeTow/Haul Mode on page 2-36and
Towing a Trailer on page 4-55for more information.
While using the DSC, cruise control and the tow/haul
mode can be used.

Cruise Grade Braking
Cruise Grade Braking operates while Cruise Control
is engaged in Tow/Haul mode to assist in maintaining
vehicle speed under loaded vehicle conditions. Cruise
Grade Braking assists when driving on a downhill grade.
It maintains vehicle speed by automatically implementing
a shift schedule that uses the engine and the
transmission to slow the vehicle. If vehicle speed is
above the desired speed the transmission will downshift
to slow the vehicle. If vehicle speed is near or below
desired speed the trans will upshift, allowing vehicle
speed to increase.
While in the Range Select Mode (RSM) mode, cruise
grade braking is not available.
SeeAutomatic Transmission Operation on page 2-32.
Full-Time Four-Wheel Drive
The Full-Time Four-Wheel Drive transfer case is
designed to constantly send the engine’s driving power
to all four wheels for extra traction. To get the most
out of Full-Time Four-Wheel Drive, you must be familiar
with its operation.
Notice:Driving on pavement in Four-Wheel
High Lock or Four Wheel Low Lock for extended
periods may cause premature wear on the vehicle
powertrain and tires. Do not drive in Four-Wheel
High Lock or Four-Wheel Low Lock on pavement
for extended periods.

Cruise Control
{CAUTION:
Cruise control can be dangerous where you cannot
drive safely at a steady speed. So, do not use the
cruise control on winding roads or in heavy traffic.
Cruise control can be dangerous on slippery roads.
On such roads, fast changes in tire traction can
cause excessive wheel slip, and you could lose
control. Do not use cruise control on slippery roads.
With cruise control, a speed of about 25 mph (40 km/h)
or more can be maintained without keeping your foot
on the accelerator. This can really help on long trips.
Cruise control does not work at speeds below about
25 mph (40 km/h).
When the brakes are applied, cruise control is
turned off.
If the vehicle has the StabiliTrak
®system or Traction
Control system (TCS) and begins to limit wheel spin
while you are using cruise control, the cruise control
automatically disengages. SeeStabiliTrak
®System on
page 4-6orTraction Control System (TCS) on page 4-9.
When road conditions allow the cruise control to be safely
uses again, it can be turned back on.The cruise control buttons
are located on the left side
of the steering wheel.
T(On/Off):Press to turn the system on or off.
The indicator light on the button turns on when cruise
control is on and turns off when cruise control is off.
+ RES (Resume/Accelerate):Press to make the
vehicle accelerate or resume to a previously set speed.
SET−(Set/Coast):Press to set the speed or make
the vehicle decelerate.
[(Cancel):Press to cancel cruise control without
erasing the set speed from memory.
3-12

Setting Cruise Control
Cruise control will not work if the parking brake is set or
if the master cylinder brake uid level is low.
The cruise control light on the instrument panel cluster
comes on after the cruise control has been set to
the desired speed.
{CAUTION:
If you leave your cruise control on when you are
not using cruise, you might hit a button and go
into cruise when you do not want to. You could be
startled and even lose control. Keep the cruise
control switch off until you want to use cruise
control.
1. Press
T.
2. Get up to the desired speed.
3. Press the SET−button located on the steering
wheel and release it.
4. Take your foot off the accelerator.
Resuming a Set Speed
If the cruise control is set at a desired speed and then
the brake is applied, this shuts off the cruise control.
But it does not need to be reset.
Once the vehicle is driving about 25 mph (40 km/h) or
more, press the +RES button on the steering wheel.
The vehicle will return to the previously set speed and
stay there.
Increasing Speed While Using Cruise
Control
To increase the cruise speed while using cruise control:
Press and hold the +RES button on the steering
wheel until the desired speed is reached, then
release it.
To increase vehicle speed in small increments,
press the +RES button. Each time this is done,
the vehicle goes about 1 mph (1.6 km/h) faster.
3-13

Reducing Speed While Using Cruise
Control
To reduce the vehicle’s speed while using cruise
control:
Press and hold the SET– button on the steering
wheel until the desired lower speed is reached,
then release it.
To slow down in small amounts, press the
SET– button on the steering wheel briey. Each time
this is done, the vehicle goes about 1 mph (1.6 km/h)
slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase the vehicle’s
speed. When you take your foot off the pedal, the
vehicle will slow down to the previously set cruise speed.
Using Cruise Control on Hills
How well the cruise control will work on hills depends
upon the vehicle’s speed, load, and the steepness of the
hills. When going up steep hills, you might have to step
on the accelerator pedal to maintain the vehicle’s speed.
When going downhill, you might have to brake or shift to
a lower gear to keep the vehicle’s speed down. When the
brakes are applied the cruise control turns off.
Ending Cruise Control
There are three ways to end cruise control:
Step lightly on the brake pedal.
Press the[button on the steering wheel.
Press theTbutton on the steering wheel.
Erasing Speed Memory
The cruise control set speed memory is erased when
the cruise control or the ignition is turned off.
