FORD 2001 Expedition - Manual (Page 164)

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.
