FORD 2013 Edge v.2 - Manual (Page 193)

USING YOUR ALL-WHEEL DRIVE (AWD) SYSTEM (IF EQUIPPED)
AWD uses all four wheels to power the vehicle. This increases traction,
enabling you to drive over terrain and road conditions that a
conventional two-wheel drive vehicles cannot. The AWD system is active
all the time and requires no input from the operator.
Note: Your AWD vehicle is not intended for off-road use. The AWD feature
gives your vehicle some limited off-road capabilities in which driving
surfaces are relatively level, obstruction-free and otherwise similar to
normal on-road driving conditions. Operating your vehicle under other than
those conditions could subject the vehicle to excessive stress which might
result in damage which is not covered under your warranty.
Note: When an AWD system fault is present, the warning Check AWD
will display in the message center. The AWD system is not functioning
correctly and defaulted to front-wheel drive. When this warning is
displayed, have your vehicle serviced at an authorized dealer.
Note: The AWD Off message may also be displayed in the message center
if the AWD system has overheated and defaulted to front-wheel drive. This
condition may occur if the vehicle was operated in extreme conditions with
excessive wheel slip, such as deep sand. To resume normal AWD function
as soon as possible, stop the vehicle in a safe location and stop the engine
for at least 10 minutes. After the engine has been restarted and the AWD
system has adequately cooled, the AWD Off message will turn off and
normal AWD function will return. The AWD Off message will turn off when
the system cools and normal AWD function returns.
If your vehicle is equipped with AWD, a spare tire of a different size
other than the tire provided should never be used. If the mini-spare tire
is installed, the AWD system may disable automatically and enter
front-wheel drive only mode to protect driveline components. This
condition may be indicated by an AWD Off message in the information
display. If there is an AWD Off message in the message center from using
the spare tire, this indicator should turn off after reinstalling the repaired
or replaced normal road tire and cycling the ignition off and on. It is
recommended to reinstall the repaired or replaced road tire as soon as
possible. Major dissimilar tire sizes between the front and rear axles
could cause the AWD system to stop functioning and default to
front-wheel drive or damage the AWD system.
Driving In Special Conditions With All-Wheel Drive (AWD)
AWD vehicles are equipped for driving on sand, snow, mud and rough
roads and have operating characteristics that are somewhat different
from conventional vehicles, both on and off the highway.
