CONTROL-TRAC AUTOMATIC
FOUR-WHEEL DRIVE SYSTEM
(IF EQUIPPED)
Your 4x4 features a heavy-duty
Control-Trac system, including a
computer-operated transfer case.
Coupled with a
center-disconnected front axle, this
unique system is interactive with
the road, continually monitoring
and adjusting torque delivery to
the front and rear wheels to
optimize vehicle control.
Positions of the Control-Trac
system
The Control-Trac A4WD system
functions in four modes:
²2Hposition delivers power only
to the rear axle.
²A4WDposition delivers power
to the rear axle. If the rear
wheels lose traction, power will
be automatically delivered to the
front axle to maintain traction
throughout the slippery
condition.
²4Hposition provides
mechanically locked four-wheel
drive power delivery to front
and rear axles.
²4Lposition provides

conditions. Avoid sharp turns or
abrupt maneuvers in these
vehicles.
Using the Control-Trac system
Shifting to A4WD
