FORD 2014 Taurus v.2 - Manual (Page 189)

Using your All Wheel Drive (AWD) system
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 information display. 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 information
display 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. In the event
the engine is not stopped, the AWD Off message will turn off when the
system cools and normal AWD function returns.
The Power Transfer Unit (PTU) does not require any normal scheduled
maintenance. Do not check or change the PTU lubricant unless the unit
has been submerged in water or shows signs of leakage
The Power Transfer Unit (PTU) in Taurus SHO™ performance package
vehicles is electronically monitored and notifies the driver of required
service by displaying the message Change AWD Power Transfer Unit
Lube in the information display. The PTU lube will be more likely to
require a fluid change if the vehicle has experienced extended periods of
extreme/severe duty cycle driving. Do not check or change the PTU
lubricant unless the unit has been submerged in water, shows signs of
leakage or a message indicating required service is displayed. Contact
your authorized dealer for service and to reset the PTU lube life monitor.
Do not use a spare tire of a different size other than the tire provided.
If the mini-spare tire is installed, the AWD system may disable
automatically and enter front-wheel drive only mode to protect driveline
