Power Transfer Unit FORD FLEX 2019 Owners Manual

WARNING: The use of
non-recommended tires and wheels could
cause steering, suspension, axle, transfer
case or power transfer unit failure. If you
have questions regarding tire replacement,
contact your authorized dealer as soon as
possible.
Major dissimilar tire sizes between the front
and rear axles (for example, 17 inch low
profile tires on the front axle and 22 inch
high profile tires on the rear axle) could
cause the AWD system to stop functioning
and default to front-wheel drive or damage
the AWD system. However, the AWD
system is capable of tolerating any
combination of new and worn tires of the
same original tire size. For example, using
3 worn tread tires and 1 new tread tire all
of the same original tire size, can be
tolerated by 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.
When driving at slow speeds in deep sand
under high outside temperatures, use a low
gear when possible. Lower gear operation
will maximize the engine and transmission
cooling capability.
Under severe operating conditions, the A/C
may cycle on and off to protect
overheating of the engine. Basic operating principles in special
conditions
•
Drive slower in strong crosswinds which
can affect the normal steering
characteristics of your vehicle.
• Be extremely careful when driving on
pavement made slippery by loose sand,
water, gravel, snow or ice.
If Your Vehicle Goes Off the Edge of the
Pavement
• If your vehicle goes off the edge of the
pavement, slow down, but avoid severe
brake application, ease the vehicle
back onto the pavement only after
reducing your speed. Do not turn the
steering wheel too sharply while
returning to the road surface.
• It may be safer to stay on the apron or
shoulder of the road and slow down
gradually before returning to the
pavement. You may lose control if you
do not slow down or if you turn the
steering wheel too sharply or abruptly.
• It often may be less risky to strike small
objects, such as highway reflectors,
with minor damage to your vehicle
rather than attempt a sudden return to
the pavement which could cause the
vehicle to slide sideways out of control
or rollover. Remember, your safety and
the safety of others should be your
primary concern.
If Your Vehicle Gets Stuck WARNING:
Always fully apply the
parking brake. Make sure you shift into park
(P) for vehicles with an automatic
transmission. Switch the ignition off and
remove the key whenever you leave your
vehicle.

system has adequately cooled, the AWD
OFF message turns off and normal AWD
function returns. In the event the engine is
not stopped, the AWD OFF message turns
off when the system cools and normal
AWD function returns.
When driving at slow speeds in deep sand
under high outside temperatures, use L
(Low) gear when possible. L (Low) gear
operation will maximize the engine and
transmission cooling capability.
Under severe operating conditions, the A/C
may cycle on and off to protect
overheating of the engine.
Avoid excessive speed because vehicle
momentum can work against you and
cause the vehicle to become stuck to the
point that assistance may be required from
another vehicle. Remember, you may be
able to back out the way you came if you
proceed with caution.
Mud and Water
If you must drive through high water, drive
slowly. Traction or brake capability may
be limited.
When driving through water, determine the
depth; avoid water higher than the bottom
of the wheel rims (for cars) or the bottom
of the hubs (for trucks) (if possible) and
proceed slowly. If the ignition system gets
wet, the vehicle may stall.
Once through water, always try the brakes.
Wet brakes do not stop the vehicle as
effectively as dry brakes. Drying can be
improved by moving your vehicle slowly
while applying light pressure on the brake
pedal. Be cautious of sudden changes in vehicle
speed or direction when you are driving in
mud. Even AWD vehicles can lose traction
in slick mud. As when you are driving over
sand, apply the accelerator slowly and
avoid spinning your wheels. If the vehicle
does slide, steer in the direction of the slide
until you regain control of the vehicle.
After driving through mud, clean off residue
stuck to rotating driveshafts and tires.
Excess mud stuck on tires and rotating
driveshafts causes an imbalance that
could damage drive components.
Note:
Driving through deep water may
damage the transmission.
If the front or rear axle is submerged in
water, have the power transfer unit (PTU)
or rear axle serviced by an authorized
dealer. “Tread Lightly
” is an educational program
designed to increase public awareness of
land-use regulations and responsibilities
in our nations wilderness areas. Ford Motor
Company joins the U.S. Forest Service and
the Bureau of Land Management in
encouraging you to help preserve our
national forest and other public and private
lands by “treading lightly. ”
Driving on Hilly or Sloping Terrain
Note: Avoid driving crosswise or turning on
steep slopes or hills. A danger lies in losing
traction, slipping sideways and possibly
rolling over. Whenever driving on a hill,
determine beforehand the route you will
use. Do not drive over the crest of a hill
without seeing what conditions are on the
other side. Do not drive in reverse over a hill
without the aid of an observer.

Note:
Your vehicle may be
equipped with a dissimilar spare
wheel and tire assembly. A
dissimilar spare wheel and tire
assembly is defined as a spare
wheel and tire assembly that is
different in brand, size or
appearance from the road tires and
wheels. If you have a dissimilar
spare wheel and tire assembly, it is
intended for temporary use only
and should not be used in a tire
rotation.
Note: After having your tires
rotated, inflation pressure must be
checked and adjusted to the
vehicle requirements.
Rotating your tires at the
recommended interval will help
your tires wear more evenly,
providing better tire performance
and longer tire life. Sometimes
irregular tire wear can be
corrected by rotating the tires. See
Scheduled Maintenance (page
442). USING SNOW CHAINS
WARNING:
Snow tires must be the
same size, load index, and speed rating as
those originally provided by Ford. Use of
any tire or wheel not recommended by
Ford can affect the safety and
performance of your vehicle, which could
result in an increased risk of loss of vehicle
control, vehicle rollover, personal injury,
and death. Additionally, the use of
non-recommended tires and wheels could
cause steering, suspension, axle, transfer
case, or power transfer unit failure. It is also
strongly advised to follow the Ford
recommended tire inflation pressure found
on the Safety Compliance Certification
Label (affixed to either the door hinge
pillar, door-latch post, or the door edge
that meets the door-latch post, next to the
driver ’s seating position), or Tire Label
which is located on the B-Pillar or the edge
of the driver door. Failure to follow the tire
pressure recommendations can cause
uneven treadwear patterns and adversely
affect the way your vehicle handles.
Note: The suspension insulation and
bumpers will help prevent vehicle damage.
Do not remove these components from your
vehicle when using snow tires and chains.
The tires on your vehicle have all-weather
treads to provide traction in rain and snow.
However, in some climates, you may need
to use snow tires and cables. If you need
to use cables, it is recommended that steel
wheels (of the same size and
specifications) be used, as cables may chip
aluminum wheels.

Exceptions
There are several exceptions to the Normal
Schedule:
Axle and PTU maintenance
: The Power
Transfer Unit (PTU) and rear axle (AWD
only) in your vehicle does not require any
normal scheduled maintenance. The PTU
lubricant will be more likely to require a
fluid change if the vehicle has extended
periods of extreme or severe duty cycle
driving. Changing or checking the PTU
lubricant is not necessary unless the unit
has been submerged in water or shows
signs of leakage. Contact your authorized
dealer for service. California fuel filter replacement: If you
register your vehicle in California, the
California Air Resources Board has
determined that the failure to perform this
maintenance item does not nullify the
emission warranty or limit recall liability
before the completion of your vehicle's
useful life. Ford Motor Company, however,
urges you to have all recommended
maintenance services performed at the
specified intervals and to record all vehicle
service.
Hot climate oil change intervals
:
Vehicles operating in the Middle East,
North Africa, Sub-Saharan Africa or
locations with similar climates using an
American Petroleum Institute (API)
Certified for Gasoline Engines (Certification
mark) oil of SM or SN quality, the normal
oil change interval is 5,000 mi (8,000 km)
