brakes FORD FLEX 2009 1.G User Guide

When an event occurs that activates AdvanceTrac
with RSC you may
experience the following:
•A slight deceleration of the vehicle
•The “sliding car”
indicator light will flash.
•A vibration in the pedal when your foot is on the brake pedal
•If the driving condition is severe and your foot is not on the brake, the
brake pedal may move as the systems applies higher brake forces. You
may also hear a whoosh of air from under the instrument panel during
this severe condition.
•The brake pedal may feel stiffer than usual.
Traction Control (TCS)
Traction Control is a driver aid feature that helps your vehicle maintain
traction of the wheels, typically when driving on slippery and/or hilly
road surfaces, by detecting and controlling wheel spin.
Excessive wheel spin is controlled in two ways, which may work
separately or in tandem: Engine Traction Control and Brake Traction
Control. Engine Traction Control works to limit drive-wheel spin by
momentarily reducing engine power. Brake Traction Control works to
limit wheel spin by momentarily applying the brakes to the wheel that is
slipping. Traction Control is most active at low speeds.
During Traction Control events the “sliding car” icon
in the
instrument cluster will flash.
If the Traction Control system is activated excessively in a short period
of time, the braking portion of the system may become temporarily
disabled to allow the brakes to cool down. In this situation, Traction
Control will use only engine power reduction or transfer to help control
the wheels from over-spinning. When the brakes have cooled down, the
system will regain all features. Anti-lock braking, RSC, and ESC are not
affected by this condition and will continue to function during the
cool-down period.
The Engine Traction Control and Brake Traction Control system may be
deactivated in certain situations. See theSwitching Off AdvanceTrac

with RSCsection following.

Electronic Stability Control (ESC)
Electronic Stability Control (ESC) may enhance your vehicle’s directional
stability during adverse maneuvers, for example when cornering severely
or avoiding objects in the roadway. ESC operates by applying brakes to
one or more of the wheels individually and, if necessary, reducing engine
power if the system detects that the vehicle is about to skid or slide
laterally.
During Electronic Stability Control events the “sliding car” icon
in the
instrument cluster will flash.
Certain adverse driving maneuvers may activate the Electronic Stability
Control system, which include but are not limited to:
•Taking a turn too fast
•Maneuvering quickly to avoid an accident, pedestrian or obstacle
•Driving over a patch of ice or other slippery surfaces
•Changing lanes on a snow-rutted road
•Entering a snow-free road from a snow-covered side street, or vice
versa
•Entering a paved road from a gravel road, or vice versa
•Cornering while towing a heavily loaded trailer (refer toTrailer
towingin theTires, Wheels and Loadingchapter).
The Electronic Stability Control system may be deactivated in certain
situations. See theSwitching Off AdvanceTrac
with RSCsection
following.
Roll Stability Control™ (RSC)
Roll Stability Control (RSC) may help to maintain roll stability of the
vehicle during adverse maneuvers. RSC operates by detecting the
vehicle’s roll motion and the rate at which it changes and by applying the
brakes to one or more wheels individually.
During an event that activates the Roll Stability Control™ (RSC) the
“sliding car” icon
in the instrument cluster will flash.
Certain adverse driving maneuvers may activate the Roll Stability Control
system, which include:
•Emergency lane-change
•Taking a turn too fast
•Quick maneuvering to avoid an accident, pedestrian or obstacle

If you cannot move the gearshift lever out of P (Park) with ignition in
the on position and the brake pedal depressed:
1. Apply the parking brake, turn
ignition key to off, then remove the
key.
2. Using a screwdriver (or similar
tool), remove the protective cover
to the interlock release access hole
on the console.
3. Insert the screwdriver (or similar
tool) into the access hole and press
downward while pulling the
gearshift lever out of the P (Park)
position and into the N (Neutral)
position.
4. Remove the tool and reinstall the
protective cover.
5. Start the vehicle and release the
parking brake.
If it is necessary to use the above procedure to move the gearshift lever,
it is possible that a fuse has blown or the vehicle’s brakelamps are not
operating properly. Refer toFuses and relaysin theRoadside
Emergencieschapter.
WARNING:Do not drive your vehicle until you verify that the
brakelamps are working.
WARNING:Always set the parking brake fully and make sure
the gearshift is latched in P (Park). Turn the ignition to the off
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 as soon as possible.

If your vehicle is equipped with Traction Control™, it may be beneficial
to disengage the Traction Control™ system while attempting to rock the
vehicle.
Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
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.
WARNING:Always set the parking brake fully and make sure
the gearshift is latched in P (Park). Switch the ignition off 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.
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.

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.

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.

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.

POWER STEERING FLUID
Refer to thescheduled maintenance informationfor the service
interval schedules.
1. Start the engine and let it run
until it reaches normal operating
temperature (the engine coolant
temperature gauge indicator will be
near the center of the normal area
between H and C).
2. While the engine idles, turn the
steering wheel left and right several
times.
3. Turn the engine off.
4. Check the fluid level in the reservoir. It should be between the MIN
and MAX lines. Do not add fluid if the level is in this range.
5. If the fluid is low, add fluid in small amounts, continuously checking
the level until it reaches the range between the MIN and MAX lines. Be
sure to put the cap back on the reservoir. Refer toMaintenance
product specifications and capacitiesin this chapter for the proper
fluid type.
BRAKE FLUID
The fluid level will drop slowly as
the brakes wear, and will rise when
the brake components are replaced.
Fluid levels between the “MIN” and
“MAX” lines are within the normal
operating range; there is no need to
add fluid. If the fluid levels are
outside of the normal operating
range the performance of the
system could be compromised; seek
service from your authorized dealer
immediately.
