brake sensor FORD EDGE 2011 1.G Owners Manual

braking which is applied by the ACC system is limited and can be
overridden by the driver applying the brakes.
If the ACC system predicts that its
maximum braking level will not be
sufficient, an audible warning will
sound while the ACC continues to
brake. This is accompanied by a
heads-up display; a red warning bar
illuminating on the windshield. The driver should takeimmediate
action.
Note:The brakes may emit a sound when they are being modulated by
the adaptive cruise control system.
WARNING:Adaptive cruise control only warns of vehicles
detected by the radar sensor. In some cases there may be no
warning or the warning may be delayed. The driver should always
apply the brakes when necessary. Failing to do so may result in a
collision, serious injury or death.
Setting the gap distance
The distance between your vehicle
and the vehicle in front of you can
be decreased or increased by
pressing the GAP control up or
down. The selected gap will be
displayed in the message center as shown by the bars in the graphic.
Four gap distance settings are available.

Hilly condition usage
It is recommended that the driver select a lower gear position when ACC
is active in situations such as prolonged downhill driving on steep grades
(i.e., driving in mountainous areas). In these situations, additional engine
braking is needed to reduce the load on the vehicle’s regular brake
system to prevent them from overheating. For more information,
referenceAutomatic transmission operationin theDrivingchapter.
Note:If ACC is applying brakes for an extended period of time, an
audible alarm will sound and ACC will shut down. This is to allow the
brakes to cool down. When the brakes have cooled down, the ACC will
again function normally.
Turning off cruise control
Press OFF to turn off the cruise control.
Note:When you turn off the cruise control or the ignition, your cruise
control set speed memory is erased.
Detection issues
The radar sensor has a limited field of vision. In some situations it may
not detect vehicles at all or detect a vehicle later than expected.
Detection issues can occur:
•When driving on a different line than the vehicle in front.

•With vehicles that edge into your lane. These vehicles can only be
detected once they have moved fully into your lane.
•There may be issues with the detection of vehicles in front when
driving into and coming out of a bend or curve in the road.
In these cases ACC may brake late or unexpectedly. The driver should
stay alert and intervene when necessary.
ACC Not Available
Several conditions exist which can cause ACC to deactivate or prevent
ACC from activating when requested. These conditions include:
•The sensor is blocked, refer toBlocked sensorin this section.
•Brake temperature is high, refer toHilly condition usagein this
section.
•A failure has occurred in the ACC system or related system.

Blocked sensor
If a message regarding a blocked
sensor is displayed, the radar signals
from the sensor have been
obstructed. The sensor is located
behind a fascia cover near the driver
side of the lower grille. When the
radar signals are obstructed, a
vehicle ahead cannot be detected
and the ACC will not function. The
following table lists possible causes
and actions for this message being
displayed.
Cause Action
The surface of the radar in the
grille is dirty or obstructed in
some wayClean the grille surface in front of
the radar or remove the object
causing the obstruction
The surface of the radar in the
grille is clean but the message
remains in the displayWait a short time. It may take
several minutes for the radar to
detect that it is no longer
obstructed
Heavy rain or snow is interfering
with the radar signalsDo not use ACC in these condition
because it may not detect, warn,
or respond to potential collisions.
Swirling water, or snow or ice on
the surface of the road may
interfere with the radar signalsDo not use ACC in these condition
because it may not detect, warn,
or respond to potential collisions.
WARNING:Do not use ACC when towing a trailer with brake
controls. Aftermarket trailer brakes will not function properly
when ACC is activated because the brakes are electronically controlled.
Failing to do so may result in loss of vehicle control, which could result
in serious injury.

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.
Press the parking brake pedal downward again to release the parking
brake. Driving with the parking brake on will cause the brakes to wear
out quickly and reduce fuel economy.
Note:If the vehicle is driven with the parking brake applied, a chime
will sound.
ADVANCETRACWITH ROLL STABILITY CONTROL™ (RSC)
STABILITY ENHANCEMENT SYSTEM
The AdvanceTracwith RSCsystem provides the following stability
enhancement features for certain driving situations:
•Traction control system (TCS), which functions to help avoid
drive-wheel spin and loss of traction.
•Electronic stability control (ESC), which functions to help avoid skids
or lateral slides
•Roll Stability Control™ (RSC), which functions to help avoid a
vehicle roll-over.
WARNING:Vehicle modifications involving braking system,
aftermarket roof racks, suspension, steering system, tire
construction and/or wheel/tire size may change the handling
characteristics of the vehicle and may adversely affect the performance
of the AdvanceTracwith RSCsystem. In addition, installing any
stereo loudspeakers may interfere with and adversely affect the
AdvanceTracwith RSCsystem. Install any aftermarket stereo
loudspeaker as far as possible from the front center console, the
tunnel, and the front seats in order to minimize the risk of interfering
with the AdvanceTracwith RSCsensors. Reducing the effectiveness
of the AdvanceTracwith RSCsystem could lead to an increased risk
of loss of vehicle control, vehicle rollover, personal injury and death.

Hill start assist (HSA) system
The hill start assist system makes it easier to pull away when the vehicle
is on a slope without the need to use the parking brake. When hill start
assist is active, the vehicle will remain stationary on the slope for up to
three seconds after you release the brake pedal. During this time, you
have time to move your foot from the brake to the accelerator pedal and
pull away. The brakes are released automatically once the engine has
developed sufficient drive to prevent the vehicle from rolling down the
slope. This is an advantage when pulling away on a slope; for example
from a car park ramp, traffic lights or when reversing uphill into a
parking space.
WARNING:The hill start assist system does not replace the
parking brake. When you leave the vehicle, always apply the
parking brake and select first or reverse gear.
Using hill start assist
Hill start assist is activated automatically when the vehicle is stopped on
a slope greater than five degrees. Hill start assist operates with the
vehicle facing downhill if reverse gear is selected.
WARNING:You must remain in the vehicle once you have
activated hill start assist.
Activating hill start assist
1. Press the brake pedal to bring the vehicle to a complete standstill.
Keep the brake pedal pressed.
2. If the sensors detect that the vehicle is on a slope, hill start assist will
be activated automatically.
3. When you remove your foot from the brake pedal, the vehicle will
remain on the slope without rolling away for approximately up to three
seconds. This hold time will automatically be extended if you are in the
process of driving off.
4. Drive off in the normal manner. The brakes will be released
automatically.
WARNING:If the engine is revved excessively, or if a
malfunction is detected when hill start assist is active, hill start
assist will be deactivated.

Operation
The radar sensor detects vehicles
ahead that are moving in the same
direction as your vehicle.
If the radar detects that your
vehicle is rapidly closing on another
vehicle a red warning light will
illuminate and an audible warning
chime will sound.
After that, if the risk of collision
further increases after the warning
light, the brake support prepares
the brake system for rapid braking.
This may be apparent to the driver.
However, the system will not
automatically activate the brakes.
The vehicle will not stop unless the driver presses the brake pedal. If the
brake pedal is pressed then braking is implemented with full brake
function, even if the force on the brake pedal is light.
The collision warning system is active at speeds above approximately
5 mph (8 km/h).
Collision warning system limitations
Due to the nature of radar technology, there may be certain instances
where vehicles will not provide a collision warning. These include:
•Stationary or slow moving vehicles below 6 mph (10 km/h).
•Pedestrians or objects in the roadway.
•Oncoming vehicles in the same lane.
•Severe weather conditions (see also blocked sensor section).
•Debris build-up on the grille near the headlamps (see block sensor
section).
•Small distance to vehicle ahead.
•Steering wheel and pedal movements are large (very active driving
style).
•High interior temperatures, which may deactivate the illumination or
the warning lamps until the interior temperature reduces (audible
warning will alert the driver).
In addition, sun load and sunglasses may reduce the visibility of the
warning lamps. Therefore, it is recommended to keep the audible
warning on.

WARNING:The collision warning system’s brake support can
only help reduce the speed at which a collision occurs if the
driver applies the vehicle’s brakes. The brake pedal must be pressed
just like for any typical braking situation.

CHANGING THE TIRES
If you get a flat tire while driving, do not apply the brake heavily.
Instead, gradually decrease your speed. Hold the steering wheel firmly
and slowly move to a safe place on the side of the road.
Note:The tire pressure monitoring system (TPMS) indicator light will
illuminate when the spare tire is in use. To restore the full functionality
of the monitoring system, all road wheels equipped with tire pressure
monitoring sensors must be mounted on the vehicle.
Have a flat serviced by an authorized dealer in order to prevent damage
to the TPMS sensors, refer toTire pressure monitoring system
(TPMS)in theTires, Wheels and Loadingchapter. Replace the spare
tire with a road tire as soon as possible. During repairing or replacing of
the flat tire, have the authorized dealer inspect the TPMS sensor for
damage.
WARNING:The use of tire sealants may damage your tire
pressure monitoring system (TPMS) and should not be used.
However, if you must use a sealant, the TPMS sensor and valve stem
on the wheel must be replaced by an authorized Ford dealer.
WARNING:Refer toTire pressure monitoring system (TPMS)
in theTires, Wheels and Loadingchapter for important
information. If the tire pressure monitor sensor becomes damaged, it
will no longer function.
Dissimilar spare tire/wheel information
WARNING:Failure to follow these guidelines could result in an
increased risk of loss of vehicle control, injury or death.
If you have a dissimilar spare tire/wheel, then it is intended for
temporary use only. This means that if you need to use it, you should
replace it as soon as possible with a road tire/wheel that is the same size
and type as the road tires and wheels that were originally provided by
Ford. If the dissimilar spare tire or wheel is damaged, it should be
replaced rather than repaired.
