Range Selection Mode
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 3‑28.
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 3‑34.
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.
Transfer Case Buttons
The vehicle will have one of these three styles of
transfer case controls. Use these controls to shift into
and out of the different Four-Wheel Drive modes.
1-21
Automatic Transfer Case
This transfer case knob is located next to the steering
column.
Each transfer case design offers different drive options.
The list below described the different drive options that
may be available.
2
m(Two-Wheel-Drive High):This setting is used for
driving in most street and highway situations.
AUTO (Automatic Four-Wheel Drive): This setting is
ideal for use when road surface traction conditions are
variable. 4
m(Four-Wheel High):
Use the Four-Wheel-Drive High
position when extra traction is needed, such as on
snowy or icy roads or in most off-road situations.
N (Neutral): Shift the transfer case to Neutral only when
towing the vehicle. See Recreational Vehicle Towing
on
page 5‑44or Towing a Trailer on page 5‑51.
4
n(Four-Wheel-Drive Low): This setting 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.
See Four-Wheel Drive on page 3‑36.
1-23
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. To get the most satisfaction out of Four-Wheel
Drive, you must be familiar with its operation. Read the
following before using Four-Wheel Drive. See the
appropriate text for the transfer case in the vehicle.
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 vibration in the steering
system.
If 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.
Manual Transfer Case
The transfer case shift lever is on the floor to the right of
the driver. Use this lever to shift into and out of
Four-Wheel Drive.
3-36
Automatic Transfer Case
The transfer case knob is
located next to the
steering column.
Use the dial to shift into and out of Four-Wheel Drive.
You can choose among five driving settings:
Indicator lights in the dial show which setting you are in.
The indicator lights will come on briefly when you turn
on the ignition and one 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 the
transfer case. It will remain illuminated when the shift is
complete. 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 the vehicle in AUTO, the front
axle is engaged, but the vehicle's power is sent only to
the front and rear wheels automatically based on driving
conditions. 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-Drive High position when extra traction is
needed, such as on snowy or icy roads or in most
off-road situations. This setting also engages the 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.
If the vehicle has StabiliTrak
®, shifting into
Four-Wheel-Drive Low will turn Traction Control and
StabiliTrak
®off. See StabiliTrak®System on page 5‑6.
