Four-Wheel Drive
If your vehicle has four-wheel drive, you will see the
buttons shown below. You can send your 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 part that
follows before using four-wheel drive.
Notice: Driving on clean, dry pavement in
four-wheel drive 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 for extended periods of time.
The transfer case buttons
are located to the left of
the instrument panel
cluster.
Front Axle Locking Feature
The front axle locks and unlocks automatically when
you shift the transfer case. Some delay for the axle to
lock or unlock is normal.
For four-wheel drive vehicles with StabiliTrak
®
, see
StabiliTrak
®
System on page 4-10.
Use these buttons to shift into and out of four-wheel
drive.
You can choose among four driving settings:
AUTO 4WD (Automatic Four-Wheel Drive): This
setting is ideal for use when road surface traction
conditions are variable. When driving your vehicle in
AUTO 4WD, the front axle is engaged, but the vehicle’s
power is sent only to the rear wheels. When the
vehicle senses a loss of traction, the system will
automatically engage four-wheel drive. Driving in this
mode results in slightly lower fuel economy than
Two-Wheel High.
2
m
(Two Wheel-High): This setting is used for
driving in most street and highway situations. Your front
axle is not engaged in two-wheel drive. This setting
also provides the best fuel economy.
