USING FOUR-WHEEL DRIVE (4WD) (if equipped)
WARNING: For important information regarding safe operation
of this type of vehicle, see General Information in the Wheels
and Tires chapter.
Note: Do not use 4X4 mode on dry, hard surfaced roads. Doing so will
produce excessive noise, increase tire wear and may damage drive
components. 4X4 mode is only intended for consistently slippery or loose
surfaces.
Your 4x4 features the heavy-duty Control Trac® 4WD system which
includes a computer-operated transfer case. This unique system is
interactive with the road, continually monitoring and adjusting torque
delivery to the front and rear wheels to optimize vehicle control.

4WD Indicator Lights

The indicator lights illuminate in the message center in the
reconfigurable telltale (RTT) location under the following conditions.
Refer to Warning Lamps and Indicators in the Instrument Cluster
chapter.
Note: When a 4X4 system fault is present, the system will typically
remain in whichever 4X4 mode was selected prior to the fault condition
occurring. It will not default to 4X2 in all circumstances. When this
warning is displayed, have your vehicle serviced by an authorized dealer.
4X2 - Momentarily illuminates when 2H is selected.
4X4 AUTO - Continuously illuminates when 4A is selected
4X4 - Continuously illuminates when 4H is selected.
