4Wd Operation Is Not; 4Wd System Indicator Lights - Ford F150 1997 Owner's Manual

Driving
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.

4WD operation is not

recommended on dry pavement.
Doing so could result in difficult
disengagement of the transfer
case, increased tire wear and
decreased fuel economy.
