Range Selection Mode
Base trim shown (uplevel similar)
The Range Selection Mode switch is located on the
shift lever. To enable the Range Selection feature,
move the column shift lever to the M (Manual) position. The current range will appear next to the M. This is the
highest attainable range with all lower gears accessible.
As an example, when 4 (Fourth) gear is selected,
1 (First) through 4 (Fourth) gears are available.
Press the plus/minus buttons, located on the steering
column shift lever, to select the desired range of
gears for current driving conditions. See
Automatic
Transmission Operation on page 3‑32.
While using Range Selection Mode, cruise control and
the Tow/Haul mode can be used.
Grade Braking is not available when Range Selection
Mode is active. See Tow/Haul Mode on page 3‑38.
Four-Wheel Drive
If the vehicle has Four-Wheel Drive, you can send the
engine's driving power to all four wheels for extra
traction.

four wheels. You might choose Four-Wheel-Drive Low if
you are driving off-road in deep sand, deep mud, deep
snow, and while climbing or descending steep hills.
N (Neutral): Vehicles with a two speed transfer case
have a N (Neutral) position. Shift the transfer case
to N (Neutral) only when towing the vehicle. See

{WARNING:
It is dangerous to get out of the vehicle if the shift
lever is not fully in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure the
vehicle will not move, even when you are on fairly
level ground, always set the parking brake and
move the shift lever to P (Park). SeeShifting Into
Park
on page 3‑47. If you are pulling a trailer,
see Towing a Trailer on page 5‑47.
{WARNING:
If the vehicle has a four-wheel drive transfer
case with a N (Neutral) position, and the transfer
case is in N (Neutral), the vehicle will be free
to roll —even if the shift lever is in P (Park).
(Continued)
WARNING: (Continued)
Be sure the transfer case is in a drive gear,
Two-Wheel Drive High or Four-Wheel Drive High
or Four-Wheel Drive Low—not in N (Neutral). See
Shifting Into Park
on page 3‑47. Always set the
parking brake.
R (Reverse): Use this gear to back up.
Notice: Shifting to R (Reverse) while the vehicle is
moving forward could damage the transmission.
The repairs would not be covered by the vehicle
warranty. Shift to R (Reverse) only after the vehicle
is stopped.
To rock the vehicle back and forth to get out of snow,
ice, or sand without damaging the transmission, see
If Your Vehicle is Stuck in Sand, Mud, Ice, or Snow
on
page 5‑27.

Grade Braking assists in maintaining desired
vehicle speeds when driving on downhill grades by
automatically implementing a shift schedule that utilizes
the engine and transmission to slow the vehicle. This
reduces wear on the braking system and increases
control of the vehicle. Grade Braking monitors vehicle
speed, acceleration, engine torque and brake pedal
usage. Using this information, it detects when the truck
is on a downhill grade and the driver desires to slow the
vehicle by pressing the brake.
Also seeTowing a Trailer
on page 5‑47for more
information.
Cruise Grade Braking (Hydra-Matic®
6-Speed Automatic Transmission)
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.
Cruise Grade Braking operates while Cruise Control is
engaged in Tow/Haul mode to assist in maintaining
vehicle speed under loaded vehicle conditions.
It utilizes vehicle acceleration and deviation from
desired speed to determine the correct gear for the
operating condition. 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.
See
Automatic Transmission Operation on page 3‑32.
Four-Wheel Drive (Two Speed
Automatic Transfer Case)
If the vehicle has four-wheel drive, you can send the
engine's driving power to all four wheels for extra
traction. Read the following before using four-wheel
drive.
Notice: Driving on clean, dry pavement in
Four-Wheel Drive High or Four-Wheel Drive Low for
an extended period of time may cause premature
wear on your vehicle's powertrain. Do not drive on
clean, dry pavement in Four-Wheel Drive High or
Four-Wheel Drive Low for extended periods of time.
While driving on clean dry pavement and during tight
turns, you may experience a vibration in the steering
system.
The vehicle has StabiliTrak
®. Shifting into
Four-Wheel-Drive Low will turn Traction Control and
StabiliTrak
®off. See StabiliTrak®System on page 5‑6.
Front Axle
The front axle engages and disengages automatically
when you shift the transfer case. Some delay for the
axle to engage or disengage is normal.
3-39

Automatic Transfer Case
The transfer case knob is
located to the left of the
instrument panel cluster.
Use this dial to shift into and out of four-wheel drive.
You can choose among five driving settings:
Indicator lights in the switches show you which setting
you are in. The indicator lights will come on briefly when
you turn on the ignition and the last chosen setting will
stay on. If the lights do not come on, you should take
the vehicle to your dealer for service. An indicator light
will flash while shifting. It will stay on when the shift is
completed. If for some reason the transfer case cannot
make a requested shift, it will return to the last chosen
setting. 2
m(Two-Wheel Drive High):
This setting is used for
driving in most street and highway situations. The front
axle is not engaged in two-wheel drive. This setting also
provides the best fuel economy.
AUTO (Automatic Four-Wheel Drive): This setting is
ideal for use when road surface traction conditions are
variable. When driving your vehicle in AUTO, the front
axle is engaged, but the vehicle's power is primarily
sent to the rear wheels. When the vehicle's software
determines a need for more traction, the system will
transfer more power to the front wheels. Driving in this
mode results in slightly lower fuel economy than
Two-Wheel Drive High.
4
m(Four-Wheel Drive High): Use the four-wheel high
position when you need extra traction, such as on
snowy or icy roads or in most off-road situations. This
setting also engages your front axle to help drive the
vehicle. This is the best setting to use when
plowing snow.
4
n(Four-Wheel Drive Low) : This setting also
engages the front axle and delivers extra torque.
You may never need this setting. It sends maximum
power to all four wheels. You might choose Four-Wheel
Drive Low if you are driving off-road in deep sand, deep
mud, deep snow, and while climbing or descending
steep hills.
