Four-Wheel Drive; Using Four-Wheel Drive - Ford F-150 Owner's Manual

USING FOUR-WHEEL DRIVE

Note: For important information regarding
safe operation of this type of vehicle, see
General Information in the Wheels and Tires
chapter.
Note: Do not use 4H or 4L mode on dry,
hard surfaced roads. Doing so can produce
excessive noise, increase tire wear and may
damage drive components. 4H or 4L mode
is only intended for consistently slippery or
loose surfaces. Use of 4L mode on these
surfaces may produce some noise (such as
occasional clunks), but will not damage
drive components.
Note: If 4L is selected while your vehicle is
moving above 3 mph (5 km/h), the 4WD
system will not perform a shift. This is
normal and should be no reason for concern.
Refer to Shifting to or from 4L (4X4 Low)
for proper operation.
Note: You can switch on and switch off the
electronic locking differential by pulling the
4WD control (4WD vehicles) or turning the
electronic locking differential control (2WD
vehicles). See Electronic Locking
Differential (page 201).
4WD Indicator Lights
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
in all circumstances. When this warning is
displayed, have your vehicle serviced by an
authorized dealer.
