CONTROL TRAC姞 FOUR-WHEEL DRIVE (4X4) OPERATION
(IF EQUIPPED)
WARNING: For important information regarding safe operation
of this type of vehicle, see Preparing to drive your vehicle in
this chapter.
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.
Use of 4X4 mode on these surfaces may produce some noise (such as
occasional clunks) but will not damage drive components.
Your 4x4 features the heavy-duty Control Trac 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 lights and chimes in the Instrument Cluster chapter.
• 4X2 - Momentarily illuminates
when 2H is selected.
• 4X4 AUTO – Illuminates when
4X4 AUTO is selected.
• 4X4 – Illuminates when 4X4 is
selected.
• CHECK 4X4 (if equipped) -

present.
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 mode in all circumstances. When this
warning is displayed, have your vehicle serviced by an authorized dealer.
