FORD 2010 Flex v.2 - Manual (Page 285)

• One of the parked vehicles has a high altitude attachment (i.e. salt
sprayer, snow plow, moving truck high bed, etc.) High altitude
attachments may not be detected by the system.
• The parking space length or parked objects position have changed
after the vehicle has passed the parking space.
• The temperature around your vehicle changed quickly such as you
just drove from a heated garage into the cold or just left a car wash.
As a result, the outside air temperature displayed in the vehicle may
not be close enough to the actual temperature. APA relies on a
correctly sensing the temperature outside for precisely positioning the
vehicle.
ALL-WHEEL DRIVE (AWD) SYSTEM (IF EQUIPPED)
Your vehicle may be equipped with a full-time all-wheel drive (AWD)
system. The AWD system is an active system, meaning it not only
responds to wheel slip between the front and rear axles but also has the
ability to anticipate wheel slip and transfer torque to the rear wheels
before slip occurs. The AWD system is active all the time and requires no
input from the operator.
All components of the AWD system are sealed for life and require no
maintenance.
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
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 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 message
center (see Message center section in the Instrument Cluster chapter
for more information). 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 driving a short
distance. 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.
Note: The AWD OFF message may also be displayed in the message
center if the AWD system has overheated and defaulted to front-wheel
