2009 FORD FLEX engine

AWD Systems (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 vehicle cannot.
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 spinning the wheels.
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.
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 (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.
If the engine, transmission, AWD system components or axles are
submerged in water, their fluids should be checked and changed, if
necessary.

Driving through deep water may damage the engine or
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.
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.
“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
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.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.
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 turn around 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.

Maintenance and Modifications
The suspension and steering systems on your vehicle have been designed
and tested to provide predictable performance whether loaded or empty
and durable load carrying capability. For this reason, Ford Motor
Company strongly recommends that you do not make modifications such
as adding or removing parts (such as lift kits or stabilizer bars) or by
using replacement parts not equivalent to the original factory equipment.
Any modifications to a vehicle that raise the center of gravity can make
it more likely the vehicle will rollover as a result of a loss of control.
Ford Motor Company recommends that caution be used with any vehicle
equipped with a high load or device (such as ladder or luggage racks).
Failure to maintain your vehicle properly may void the warranty, increase
your repair cost, reduce vehicle performance and operational capabilities
and adversely affect driver and passenger safety. Frequent inspection of
vehicle chassis components is recommended if the vehicle is subjected to
heavy off-highway usage.
DRIVING THROUGH WATER
If driving through deep or standing
water is unavoidable, proceed very
slowly especially when the depth is
not known. Never drive through
water that is higher than the bottom
of the wheel rims (for cars) or the
bottom of the hubs (for trucks).
When driving through water, traction or brake capability may be limited.
Also, water may enter your engine’s air intake and severely damage your
engine or your vehicle may stall.Driving through deep water where
the transmission vent tube is submerged may allow water into the
transmission and cause internal transmission damage.
Once through the water, always dry the brakes by moving your
vehicle slowly while applying light pressure on the brake pedal.
Wet brakes do not stop the vehicle as quickly as dry brakes.

FUEL PUMP SHUT-OFF
In the event of a moderate to severe collision, this vehicle is equipped
with a fuel pump shut-off feature that stops the flow of fuel to the
engine. Not every impact will cause a shut-off.
Should your vehicle shut off after a collision due to this feature, you may
restart your vehicle by doing the following:
1. Turn the ignition switch to the off position.
2. Turn the ignition switch to the on position.
In some instances the vehicle may not restart the first time you try to
restart and may take one additional attempt.
WARNING:Failure to inspect and if necessary repair fuel leaks
after a collision may increase the risk of fire and serious injury.
Ford Motor Company recommends that the fuel system be inspected
by an authorized dealer after any collision.
FUSES AND RELAYS
Fuses
If electrical components in the
vehicle are not working, a fuse may
have blown. Blown fuses are
identified by a broken wire within
the fuse. Check the appropriate
fuses before replacing any electrical
components.
Note:Always replace a fuse with one that has the specified amperage
rating. Using a fuse with a higher amperage rating can cause severe wire
damage and could start a fire.

General information
WARNING:Failure to follow these guidelines could result in an
increased risk of loss of vehicle control, injury or death.
Do not attempt to repair punctures larger than
14inch (6.4 mm) or
damage to the tire’s sidewall. The tire may not completely seal.
Note:Do not use the temporary mobility kit if a tire has become
severely damaged by driving the vehicle with a tire that has insufficient
air pressure. Only punctured areas located within the tire tread can be
sealed with the temporary mobility kit.
Loss of air pressure may adversely affect tire performance. For this
reason:
•Do notdrive the vehicle above 50 mph (80 km/h).
•Do notdrive further than 120 miles (200 km). Drive only to the
closest Ford Motor Company authorized dealer or tire repair shop to
have your tire inspected.
•Drive carefully and avoid abrupt steering maneuvers.
•Periodically monitor tire inflation pressure in the affected tire; if the
tire is losing pressure, have the vehicle towed.
•Read the information in theTips for use of the temporary mobility
kitsection to ensure safe operation of the temporary mobility kit and
your vehicle.
Tips for use of the temporary mobility kit
Read the following list of tips to ensure safe operation of the temporary
mobility kit:
•Before operating the temporary mobility kit, make sure your vehicle is
safely off the road and away from moving traffic. Turn on the hazard
lights.
•Always set the parking brake to ensure the vehicle doesn’t move
unexpectedly.
•Do not remove any foreign objects, such as nails or screws, from the
tire.
•When using the temporary mobility kit, leave the engine running
(only if the vehicle is outdoors or in a well-ventilated area)so
the compressor doesn’t drain the vehicle’s battery.
•Do not allow the compressor to operate continuously for more than
15 minutes; this will help prevent the compressor from overheating.
