2015 FORD FLEX transmission

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 set the parking brake fully and make sure
the gearshift is latched in P (Park). Turn the ignition to the lock
position and remove the key whenever you leave your vehicle.

WARNING:If the parking brake is fully released, but the brake
warning lamp remains illuminated, the brakes may not be
working properly. See your authorized dealer.
WARNING:Do not spin the wheels at over 35 mph (56 km/h).
The tires may fail and injure a passenger or bystander.
Note:Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Note:Do not rock the vehicle for more than a few minutes or damage to
the transmission and tires may occur or the engine may overheat.
If your vehicle gets stuck in mud or snow it may be rocked out by
shifting between forward and reverse gears, stopping between shifts, in a
steady pattern. Press lightly on the accelerator in each gear.
If your vehicle is equipped with AdvanceTrac® with Roll Stability
Control™, it may be beneficial to disengage the AdvanceTrac® with Roll
Stability Control™ system while attempting to rock the vehicle.
Emergency Maneuvers
•In an unavoidable emergency situation where a sudden sharp turn
must be made, remember to avoid “over-driving” your vehicle (i.e.,
turn the steering wheel only as rapidly and as far as required to avoid
the emergency). Excessive steering will result in less vehicle control,
not more. Additionally, smooth variations of the accelerator and/or
brake pedal pressure should be utilized if changes in vehicle speed are
called for. Avoid abrupt steering, acceleration or braking which could
result in an increased risk of loss of vehicle control, vehicle rollover
and/or personal injury. Use all available road surface to return the
vehicle to a safe direction of travel.
•In the event of an emergency stop, avoid skidding the tires and do not
attempt any sharp steering wheel movements.
•If the vehicle goes from one type of surface to another (i.e., from
concrete to gravel) there will be a change in the way the vehicle
responds to a maneuver (steering, acceleration or braking). Again,
avoid these abrupt inputs.

Sand
When driving over sand, try to keep all four wheels on the most solid
area of the trail. Avoid reducing the tire pressures but shift to a lower
gear and drive steadily through the terrain. Apply the accelerator slowly
and avoid excessive wheel slip.
Do not drive your vehicle in deep sand for an extended period of time.
This could cause the AWD system to overheat and default to front-wheel
drive. If this occurs AWD Off will be displayed in the Information Display.
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.
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 driving at excessive speeds, this causes vehicle momentum to work
against you and your vehicle could 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, the axle lubricant and
PTU (power transfer unit) lubricant should be checked and changed if
necessary.
“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.
Although natural obstacles may make it necessary to travel diagonally up
or down a hill or steep incline, you should always try to drive straight up
or straight down.
When climbing a steep slope or hill, start in a lower gear rather than
downshifting to a lower gear from a higher gear once the ascent has
started. This reduces strain on the engine and the possibility of stalling.
If you do stall out, do not try to turnaround because you might roll over.
It is better to back down to a safe location.
Apply just enough power to the wheels to climb the hill. Too much
power will cause the tires to slip, spin or lose traction, resulting in loss of
vehicle control.

Descend a hill in the same gear you
would use to climb up the hill to
avoid excessive brake application and
brake overheating. Do not descend in
neutral; instead, disengage overdrive
or manually shift to a lower gear.
When descending a steep hill, avoid
sudden hard braking as you could
lose control. The front wheels have
to be turning in order to steer the
vehicle.
Your vehicle has anti-lock brakes, therefore apply the brakes steadily. Do
not “pump” the brakes.
Driving on Snow and Ice
WARNING:If you are driving in slippery conditions that require
tire chains or cables, then it is critical that you drive cautiously.
Keep speeds down, allow for longer stopping distances and avoid
aggressive steering to reduce the chances of a loss of vehicle control
which can lead to serious injury or death. If the rear end of the vehicle
slides while cornering, steer in the direction of the slide until you
regain control of the vehicle.
Note:Excessive tire slippage can cause transmission damage.
AWD vehicles have advantages over 2WD vehicles in snow and ice but
can skid like any other vehicle.
Should you start to slide while driving on snowy or icy roads, turn the
steering wheel in the direction of the slide until you regain control.
Avoid sudden applications of power and quick changes of direction on
snow and ice. Apply the accelerator slowly and steadily when starting
from a full stop.
Avoid sudden braking as well. Although an AWD vehicle may accelerate
better than a two-wheel drive vehicle in snow and ice, it won’t stop any
faster, because as in other vehicles, braking occurs at all four wheels. Do
not become overconfident as to road conditions.

Anti-Lock Brake System
This system helps you maintain steering control during emergency stops
by keeping the brakes from locking.
This lamp momentarily illuminates when you turn the ignition
on. If the light does not illuminate during start-up, remains on
or flashes, the anti-lock brake system may be disabled. Have
the system checked by an authorized dealer. If the anti-lock brake
system is disabled, normal braking is still effective.
If the brake warning lamp illuminates when you release the
parking brake, have the system checked by an authorized dealer.
HINTS ON DRIVING WITH ANTI-LOCK BRAKES
When the system is operating, the brake pedal will pulse and may travel
further. Maintain pressure on the brake pedal. You may also hear a noise
from the system. This is normal.
The anti-lock braking system will not eliminate the risks when:
•You drive too closely to the vehicle in front of you.
•Your vehicle is hydroplaning.
•You take corners too fast.
•The road surface is poor.
PARKING BRAKE
WARNING:If the parking brake is fully released, but the brake
warning lamp remains illuminated, then driving your vehicle
could result in reduced braking ability, increased stopping distances and
potential loss of brakes. See your authorized dealer as soon as possible.
WARNING:Always set the parking brake fully and make sure
that the transmission is securely latched in park (P). Failure to
set the parking brake and engage park could result in vehicle roll-away,
property damage or bodily injury.
To set the parking brake, press the parking brake pedal down to its
fullest extent.
To release the parking brake, press the parking brake pedal down again.

The system can be turned off using the information display control.
Refer to theInformation Displaychapter.
If a fault is present in the system, a warning message appears in the
information display and does not allow the driver to switch the faulted
system on.
Note:If your vehicle is equipped with MyKey®, it is possible to prevent
turning the sensing system off. Refer to theMyKey®chapter.
Using the Rear Sensing System
The rear sensors are only active when the transmission is inR.Asthe
vehicle moves closer to the obstacle, the rate of the audible warning
increases. When the obstacle is fewer than 12 inches (30 centimeters)
away, the warning sounds continuously. If a stationary or receding object
is detected farther than 12 inches (30 centimeters) from the side of the
vehicle, the tone sounds for only three seconds. Once the system detects
an object approaching, the warning sounds again.
A. Coverage area of up to 6 feet
(2 meters) from the rear bumper
(with a decreased coverage area at
the outer corners of the bumper).
The system detects certain objects while the transmission is inR:
•and moving toward a stationary object at a speed of 3 mph (5 km/h)
or less.
•but not moving, and a moving object is approaching the rear of the
vehicle at a speed of 3 mph (5 km/h) or less.
•and moving at a speed of less than 3 mph (5 km/h) and a moving
object is approaching the rear of the vehicle at a speed of less than
3 mph (5 km/h).
