USING ALL-WHEEL DRIVE
All-wheel drive 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. 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 displays
in the information display. The AWD system
is not functioning correctly and defaults to
front-wheel drive. When this warning
displays, have your vehicle serviced at an
authorized dealer.
Note: The AWD OFF message may also
appear in the information display if the AWD
system overheats and defaults to
front-wheel drive. This may occur if the
vehicle is 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
returns. If the engine is not stopped, the
AWD OFF
message turns off when the
system cools and normal AWD function
returns.
All-Wheel Drive Messages Action / Description
AWD Messages
Displayed when the system has been
automatically disabled to protect itself.
This is caused by operating the vehicle with
the compact spare tire installed or if the
system is overheating. The system will
resume normal function and clear this
message after cycling the ignition on and
off and driving a short distance with the
road tire re-installed or after the system is
allowed to cool.
AWD OFF
Displayed in conjunction with the power-
train malfunction/reduced power light
when the system is not operating properly.
If the warning stays on or continues to
come on, contact your authorized dealer
as soon as possible.

GENERAL INFORMATION
Note:
Occasional brake noise is normal. If
a metal-to-metal, continuous grinding or
continuous squeal sound is present, the
brake linings may be worn-out. Have the
system checked by an authorized dealer. If
your vehicle has continuous vibration or
shudder in the steering wheel while braking,
have it checked by an authorized dealer.
Note: Brake dust may accumulate on the
wheels, even under normal driving
conditions. Some dust is inevitable as the
brakes wear and does not contribute to
brake noise. See Cleaning the Alloy
Wheels (page 268).
Note: Depending on applicable laws and
regulations in the country for which your
vehicle was originally built, your brake lamps
may flash during heavy braking. Following
this, your hazard lights may also flash when
your vehicle comes to a stop. See
Warning Lamps and
Indicators (page 92).
Wet brakes result in reduced braking
efficiency. Gently press the brake pedal a
few times when driving from a car wash or
standing water to dry the brakes.
Brake Over Accelerator
In the event the accelerator pedal
becomes stuck or entrapped, apply steady
and firm pressure to the brake pedal to
slow the vehicle and reduce engine power.
If you experience this condition, apply the
brakes and bring your vehicle to a safe
stop. Move the transmission to park (P),
switch the engine off and apply the parking
brake. Inspect the accelerator pedal for
any interference. If none are found and the
condition persists, have your vehicle towed
to the nearest authorized dealer. Brake Assist
Brake assist detects when you brake
rapidly by measuring the rate at which you
press the brake pedal. It provides
maximum braking efficiency as long as you
press the pedal, and can reduce stopping
distances in critical situations.
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 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
Note: When the system is operating, the
brake pedal may 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.

TRAILER SWAY CONTROL (If
Equipped) WARNING
Turning off trailer sway control
increases the risk of loss of vehicle
control, serious injury or death. Ford
does not recommend disabling this feature
except in situations where speed reduction
may be detrimental (such as hill climbing),
the driver has significant trailer towing
experience, and can control trailer sway
and maintain safe operation. Note:
This feature does not prevent trailer
sway, but reduces it when it begins.
Note: This feature cannot stop all trailers
from swaying.
Note: In some cases, if your vehicle speed
is too high, the system may turn on multiple
times, gradually reducing your vehicle speed.
The system applies the brakes to the
individual wheels and reduces engine
torque to aid vehicle stability. If the trailer
begins to sway, the stability control
warning lamp flashes and a message
appears in the information display. See
Information Messages (page 105). Slow
your vehicle down, pull safely to the side
of the road and check for correct load
distribution. See
Load Carrying (page
201).
You can switch this feature off in the
information display. When you switch the
ignition on, the system automatically turns
on. RECOMMENDED TOWING
WEIGHTS
Note:
Do not exceed the trailer
weight for your vehicle
configuration listed in the chart
below.
Note: Make sure to take into
consideration trailer frontal area.
Do not exceed 20 feet² (1.86
meters²) if your vehicle can tow a
class I trailer or 40 feet² (3.72
meters²) if your vehicle can tow a
class III trailer.
Note: For high altitude operation,
reduce the gross combined weight
by 2% per 1000 feet (300 meters)
starting at the 1000 foot (300
meter) elevation point.
Note: Certain states require
electric trailer brakes for trailers
over a specified weight. Check
state regulations for this specified
weight. The maximum trailer
weights listed may be limited to
this specified weight, as the
vehicle ’s electrical system may not
include the wiring connector
needed to use electric trailer
brakes.

Trailer Lamps
WARNING
Never connect any trailer lamp wiring
to the vehicle's tail lamp wiring; this
may damage the electrical system
resulting in fire. Contact your authorized
dealer as soon as possible for assistance
in proper trailer tow wiring installation.
Additional electrical equipment may be
required. Trailer lamps are required on most towed
vehicles. Make sure all running lights, brake
lights, turn signals and hazard lights are
working. Before Towing a Trailer
Practice turning, stopping and backing up
to get the feel of your vehicle-trailer
combination before starting on a trip.
When turning, make wider turns so the
trailer wheels clear curbs and other
obstacles.
When Towing a Trailer
•
Do not drive faster than 70 mph (113
km/h) during the first 500 miles (800
kilometers).
• Do not make full-throttle starts.
• Check your hitch, electrical connections
and trailer wheel lug nuts thoroughly
after you have traveled 50 miles (80
kilometers).
• When stopped in congested or heavy
traffic during hot weather, place the
gearshift in position P to aid engine and
transmission cooling and to help A/C
performance.
• Turn off the speed control with heavy
loads or in hilly terrain. The speed
control may turn off automatically
when you are towing on long, steep
grades.
• Shift to a lower gear when driving down
a long or steep hill. Do not apply the
brakes continuously, as they may
overheat and become less effective.
• If your transmission is equipped with a
Grade Assist or Tow/Haul feature, use
this feature when towing. This provides
engine braking and helps eliminate
excessive transmission shifting for
optimum fuel economy and
transmission cooling.
• Allow more distance for stopping with
a trailer attached. Anticipate stops and
brake gradually.
• Avoid parking on a grade. However, if
you must park on a grade:
214
Flex (), enUSA, First Printing TowingE211392

•
Transmissions give their best fuel
economy when operated in the top
cruise gear and with steady pressure
on the gas pedal.
• Four-wheel-drive operation (if
equipped) is less fuel efficient than
two-wheel-drive operation.
• Close the windows for high-speed
driving.
DRIVING THROUGH WATER WARNING
Do not drive through flowing or deep
water as you may lose control of your
vehicle.
Note:
Driving through standing water can
cause vehicle damage.
Note: Engine damage can occur if water
enters the air filter.
Before driving through standing water,
check the depth. Never drive through water
that is higher than the bottom of the front
rocker area of your vehicle. When driving through standing water, drive
very slowly and do not stop your vehicle.
Your brake performance and traction may
be limited. After driving through water and
as soon as it is safe to do so: •
Lightly press the brake pedal to dry the
brakes and to check that they work.
• Check that the horn works.
• Check that the exterior lights work.
• Turn the steering wheel to check that
the steering power assist works.
FLOOR MATS WARNINGS
Always use floor mats that are
designed to fit the foot well of your
vehicle. Only use floor mats that
leave the pedal area unobstructed. Only
use floor mats that are firmly secured to
retention posts so that they cannot slip out
of position and interfere with the pedals
or impair safe operation of your vehicle in
other ways. Pedals that cannot move freely can
cause loss of vehicle control and
increase the risk of serious personal
injury. Always make sure that the floor
mats are properly attached to the
retention posts in the carpet that are
supplied with your vehicle. Floor mats must
be properly secured to both retention posts
to make sure mats do not shift out of
position. Never place floor mats or any other
covering in the vehicle foot well that
cannot be properly secured to
prevent them from moving and interfering
with the pedals or the ability to control the
vehicle. Never place floor mats or any other
covering on top of already installed
floor mats. Floor mats should always
rest on top of vehicle carpeting surface and
not another floor mat or other covering.
Additional floor mats or any other covering
will reduce the pedal clearance and
potentially interfere with pedal operation.
