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 (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.
Driving and Operating
4 (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 the front axle to help drive
the vehicle. This is the best setting
to use when plowing snow.
4 (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.
The vehicle has StabiliTrak. Shifting
into Four-Wheel-Drive Low will turn
Traction Control and StabiliTrak off.
See StabiliTrak System in the
owner manual.
