Press the plus/minus buttons,
located on the steering column shift
lever, to select the desired range of
gears for current driving conditions.
See Manual Mode on page 9 44.

cruise control and the Tow/Haul
mode can be used.

Range Selection Mode is active.
See Tow/Haul Mode on page 9 45.
If the vehicle has Four-Wheel Drive,
you can send the engine's driving
power to all four wheels for extra
traction.
The transfer case knob is located to
the left of the instrument panel
cluster. Use this knob to shift into
and out of the different Four-Wheel
Drive modes.
This setting is used for
driving in most street and highway
situations.
This setting is ideal for
use when road surface traction
conditions are variable.
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.
Vehicles with a two speed
transfer case have a Four-Wheel-
Drive Low position. 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.
