2009 FORD FLEX ABS

WARNING:Under engine misfire conditions, excessive exhaust
temperatures could damage the catalytic converter, the fuel
system, interior floor coverings or other vehicle components, possibly
causing a fire.
Powertrain malfunction/reduced
power:Illuminates when a
powertrain or a AWD fault has been
detected. Contact your authorized
dealer as soon as possible.
Brake system warning light:To
confirm the brake system warning
light is functional, it will
momentarily illuminate when the
ignition is turned to the on position
when the engine is not running, or in a position between on and start, or
by applying the parking brake when the ignition is turned to the on
position. If the brake system warning light does not illuminate at this
time, seek service immediately from your authorized dealer. Illumination
after releasing the parking brake indicates low brake fluid level or a
brake system malfunction and the brake system should be inspected
immediately by your authorized dealer.
WARNING:Driving a vehicle with the brake system warning
light on is dangerous. A significant decrease in braking
performance may occur. It will take you longer to stop the vehicle.
Have the vehicle checked by your authorized dealer. Driving extended
distances with the parking brake engaged can cause brake failure and
the risk of personal injury.
Anti-lock brake system:If the
ABS light stays illuminated or
continues to flash, a malfunction has
been detected, have the system
serviced immediately by your
authorized dealer. Normal braking is still functional unless the brake
warning light also is illuminated.
Airbag readiness:If this light fails
to illuminate when the ignition is
turned to on, continues to flash or
remains on, have the system

SEATING
WARNING:Reclining the seatback can cause an occupant to
slide under the seat’s safety belt, resulting in severe personal
injuries in the event of a collision.
WARNING:Do not pile cargo higher than the seatbacks to
reduce the risk of injury in a collision or sudden stop.
WARNING:Before returning the seatback to its original
position, make sure that cargo or any objects are not trapped
behind the seatback. After returning the seatback to its original
position, pull on the seatback to ensure that it has fully latched. An
unlatched seat may become dangerous in the event of a sudden stop or
collision.
Adjustable head restraints
Your vehicle is equipped with front row outboard head restraints that are
vertically adjustable.
WARNING:To minimize the risk of neck injury in the event of a
crash, the driver and passenger occupants should not sit in
and/or operate the vehicle, until the head restraint is placed in its
proper position. The driver should never adjust the head restraint
while the vehicle is in motion.
The adjustable head restraints
consist of:
•a trimmed energy absorbing foam
and structure (1),
•two steel stems (2),
•a guide sleeve adjust/release
button (3),
•and a guide sleeve unlock/remove
button (4).

How to use the engine block heater
Ensure the receptacle terminals are clean and dry prior to use. To clean
them, use a dry cloth.
Depending on the type of factory installed equipment, your engine block
heater system may consume anywhere between 400 watts or 1000 watts
of energy per hour. Your factory installed block heater system does not
have a thermostat; however, maximum temperature is attained after
approximately three hours of operation. Block heater operation longer
than three hours will not improve system performance and will
unnecessarily use additional electricity.
Make sure system is unplugged and properly stowed before driving the
vehicle. While not in use, make sure the protective cover seals the
prongs of the engine block heater cord plug.
BRAKES
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
and should be inspected by an authorized dealer. If the vehicle has
continuous vibration or shudder in the steering wheel while braking, the
vehicle should be inspected by an authorized dealer.
Refer toBrake system warning
lightin theInstrument Cluster
chapter for information on the brake
system warning light.
Four-wheel anti-lock brake system (ABS)
Your vehicle is equipped with an Anti-lock Braking System (ABS). This
system helps you maintain steering control during emergency stops by
keeping the brakes from locking. Noise from the ABS pump motor and
brake pedal pulsation may be observed during ABS braking and the
brake pedal may suddenly travel a little farther as soon as ABS braking is
done and normal brake operation resumes. These are normal
characteristics of the ABS and should be no reason for concern.
Using ABS
When hard braking is required, apply continuous force on the brake
pedal; do not pump the brake pedal since this will reduce the
effectiveness of the ABS and will increase your vehicle’s stopping
distance. The ABS will be activated immediately, allowing you to retain
steering control during hard braking and on slippery surfaces. However,
the ABS does not decrease stopping distance.

ABS warning lamp
The ABS lamp in the instrument
cluster momentarily illuminates
when the ignition is turned on. If
the light does not illuminate during
start up, remains on or flashes, the
ABS is disabled due to a malfunction and needs to be serviced.
Even when the ABS is disabled,
normal braking is still effective. If
your BRAKE warning lamp
illuminates with the parking brake
released, have your brake system
serviced immediately.
Parking brake
Apply the parking brake whenever
the vehicle is parked. To set the
parking brake, press the parking
brake pedal down until the pedal
stops.
The BRAKE warning lamp in the
instrument cluster illuminates and
remains illuminated (when the
ignition is turned on) until the
parking brake is released.
WARNING:Always set the parking brake fully and make sure
that the gearshift is securely latched in P (Park).
The parking brake is not recommended to stop a moving vehicle.
However, if the normal brakes fail, the parking brake can be used to stop
your vehicle in an emergency. Since the parking brake applies only the
rear brakes, the vehicle’s stopping distance will increase greatly and the
handling of your vehicle will be adversely affected.

The Roll Stability Control system may be deactivated in certain
situations. See theSwitching Off AdvanceTrac
with RSCsection
following.
Switching Off AdvanceTrac
with RSC
If the vehicle is stuck in snow, mud or sand, and seems to lose engine
power, switching off certain features of the AdvanceTrac
with RSC
system may be beneficial because the wheels are allowed to spin. This
will restore full engine power and will enhance momentum through the
obstacle. To switch off the AdvanceTrac
with RSC system press the
AdvanceTrac
with RSCOffbutton. Full features of the AdvanceTrac

with RSC system can be restored by pressing the AdvanceTrac
with
RSCOffbutton again or by turning off and restarting the engine.
If you switch off the AdvanceTrac
with RSC system, the AdvanceTrac
with RSC “Off” button will illuminate and the sliding caricon
will
illuminate steadily. Pressing the AdvanceTrac
with RSCOffbutton
again will turn off the lighted button and thesliding caricon
.
In R (Reverse), ABS and the Engine and Brake Traction Control features
will continue to function; however, ESC and RSC are disabled.

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
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.
Make sure you allow sufficient distance between you and other vehicles
for stopping. Drive slower than usual and consider using one of the lower
gears. In emergency stopping situations, apply the brake steadily. Since
your vehicle is equipped with a four wheel anti-lock brake system (ABS),
do not “pump” the brakes. Refer to theBrakessection of this chapter
for additional information on the operation of the anti-lock brake system.
