FORD 2009 Explorer Sport Trac v.1 - Manual (Page 255)

Keep the RSS sensors (located on the rear bumper/fascia) free
from snow, ice and large accumulations of dirt (do not clean the
sensors with sharp objects). If the sensors are covered, it will
affect the accuracy of the RSS.
If your vehicle sustains damage to the rear bumper/fascia, leaving
it misaligned or bent, the sensing zone may be altered causing
inaccurate measurement of obstacles or false alarms.
FOUR-WHEEL DRIVE (4WD) OPERATION (IF EQUIPPED)
WARNING: For important information regarding safe operation
of this type of vehicle, see Preparing to drive your vehicle in
this chapter.
Four–wheel drive (4WD) supplies power to all four wheels. Do not use
4X4 High or 4X4 Low on dry, hard surfaced roads. Doing so will produce
excessive noise, increase tire wear and may damage drive components.
4X4 High and 4X4 Low are only intended for consistently slippery or
loose surfaces. The use of 4X4 High or 4X4 Low on these surfaces may
produce some noise, such as occasional clunks, but will not damage the
drive system.
If equipped with the Electronic Shift 4WD System, and 4WD Low
is selected while the vehicle is moving above 3 mph (5 km/h), the
4WD system will not engage. This is normal and should be no
reason for concern. Refer to Shifting to/from 4WD Low for proper
operation.
