CONTROL-TRAC AUTOMATIC FOUR-WHEEL DRIVE SYSTEM
(IF EQUIPPED)

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.

Positions of the Control-Trac system

The Control-Trac A4WD system
functions in three modes:
A4WD position 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.

4H position provides

mechanically locked four-wheel
drive power delivery to front and rear axles.

4L position provides mechanically locked four-wheel drive when above

average power at reduced speeds is required.

Utility and four-wheel drive vehicles are not designed for
cornering at speeds as high as passenger cars any more than

low-slung sports cars are designed to perform satisfactorily under
off-road conditions. Avoid sharp turns or abrupt maneuvers in these
vehicles.
