FORD 2009 Explorer Sport Trac v.2 - Manual (Page 253)

WARNING: If your vehicle is equipped with AWD, a spare tire of
a different size than the road tires should never be used. Such a
tire could make the vehicle difficult to control as well as result in
damage to driveline components.
WARNING: 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.
Normal operation (4.0L engine vehicles only)
The AWD system is always active and requires no driver input. It is
capable of handling all road conditions, including street and highway
driving as well as off-road conditions such as deep snow, ice or shallow
sand.
Normal operation (4.6L engine vehicles only)
During normal operation the AWD system is in AWD AUTO mode (AWD
LOCKED will illuminate in the message center for four seconds when
you first start your vehicle). The 4X4 indicator in the instrument cluster
will also come on.
For instructions on selecting the AWD LOCKED mode, refer to Message
center in the Driver Controls chapter. This mode is not intended for use
on dry pavement. This mode is appropriate for severe winter or off-road
conditions such as deep snow, ice or shallow sand. The use of AWD
LOCKED on dry or hard surfaces may produce some noise, such as
occasional clunks, but will not damage the drive system.
Autolock operation (4.6L engine vehicles only)
If the AWD system begins to overheat, the system will place itself in the
Autolock mode:
• AWD LOCKED will be displayed in the message center for four
seconds and the 4x4 indicator light will illuminate in the instrument
cluster. A warning chime will also sound. This condition may clear
without any action being taken by the driver once the AWD system
has reached a safe operating temperature.
• The 4X4 indicator light in the instrument cluster will turn off when
the AWD system reaches a safe operating temperature and normal
AWD operation is restored.
