Each time you restart your vehicle, the system will select the last chosen
gap for the current driver.
Disengaging Adaptive Cruise Control
Press the brake pedal or pressCNCLto disengage the system.
Disengaging the system will not erase your previous set speed.
Overriding Adaptive Cruise Control
WARNING:Whenever the driver is overriding the ACC by
pressing the accelerator pedal, the ACC will not automatically
apply the brakes to maintain separation from any vehicle ahead.
You can override the set speed and gap distance by pressing the
accelerator pedal.
When you are overriding the system, the green indicator light
illuminates and the follow vehicle does not show in the
information display. The system will resume operation when
you release the accelerator pedal. The vehicle speed will decrease to the
set speed, or a lower speed if following a slower vehicle.
Changing the Set Speed
There are three ways to change the set speed:
•Accelerate or brake to the desired speed and pressSETupward and
release.
•Increase or decrease the speed by holdingSETupward or downward
until the desired set speed is shown on the information display. The
vehicle speed will gradually change to the selected speed.

Cause Action
Swirling water, or snow or ice on
the surface of the road may
interfere with the radar signals.Do not use system in these
conditions because it may not
detect any vehicle ahead.
You are in a desert or remote area
with no other vehicles and no
roadside objects.Wait a short time or switch to
normal cruise control.
Due to the nature of radar technology, it is possible to get a blockage
warning and not be blocked. This can happen, for example, when driving
in sparse rural or desert environments. A false blocked condition will
either self-clear or clear after a key cycle.
Switching to Normal Cruise Control
WARNING:Normal cruise control will not brake due to slower
vehicles. Always be aware of which mode is selected and apply
the brakes when necessary.
You can manually change from adaptive cruise control to normal cruise
control through the information display.
The cruise control indicator light will replace the adaptive
cruise control indicator light if normal cruise control is selected.
The gap setting will not be displayed, the system will not
automatically respond to lead vehicles and automatic braking will not be
activated. The system will default to adaptive cruise control when the
engine is started.

System Lights and Messages
The BLIS® and CTA systems
illuminate a yellow alert indicator in
the outside mirror on the side of
the vehicle the approaching vehicle
is coming from.
Note:The alert indicator dims when nighttime darkness is detected.
CTA also sounds an audible alarm and a message appears in the
information display indicating a vehicle is coming from the right or left.
CTA works with the reverse sensing system which sounds its own
audible alarm; see theParking Aidschapter.
System Sensors
WARNING:Just prior to the system recognizing a blocked
condition and alerting the driver, the number of missed objects
will increase. To help avoid injuries, NEVER use the BLIS® as a
replacement for using the side and rear view mirrors and looking over
your shoulder before changing lanes. BLIS® is not a replacement for
careful driving.
Note:It is possible to get a blockage warning with no blockage present;
this is rare and known as a false blockage warning. A false blocked
condition either self-corrects or clears after a key cycle.
The system uses radar sensors
which are located behind the
bumper fascia on each side of the
vehicle. Do not allow these areas to
become obstructed by mud, snow or
bumper stickers, as this can cause
degraded system performance.

Note:The system does not detect, warn or respond to potential
collisions with vehicles to the rear or sides of the vehicle.
Note:The collision warning system is active at speeds above
approximately 5 mph (8 km/h).
This system is designed to alert the
driver of certain collision risks. A
radar detects if your vehicle is
rapidly approaching another vehicle
traveling in the same direction as yours.
If it is, a red warning light
illuminates and an audible warning
chime sounds.
The brake support system assists the driver in reducing the collision speed
by charging the brakes. If the risk of collision further increases after the
warning light illuminates, the brake support prepares the brake system for
rapid braking. This may be apparent to the driver. The system does not
automatically activate the brakes but, if the brake pedal is pressed, full
force braking is applied even if the brake pedal is lightly pressed.
Using the Collision Warning System
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 any typical braking situation.
The warning system sensitivity can be adjusted to one of three possible
settings by using the information display control. Refer to the
Information Displayschapter.
Note:If collision warnings are perceived as being too frequent or
disturbing then the warning sensitivity can be reduced, though the
manufacturer recommends using the highest sensitivity setting where
possible. Setting lower sensitivity would lead to fewer and later system
warnings. Refer to theInformation Displayschapter for instructions on
reducing the sensitivity.

CARGO NET (IF EQUIPPED)
WARNING:The cargo net is not designed to restrain objects
during a collision or heavy braking.
The cargo net secures lightweight
objects in the cargo area. Attach the
net to the anchors provided. Do not
put more than 50 pounds
(22 kilograms) in the net.
ROOF RACKS AND LOAD CARRIERS (IF EQUIPPED)
WARNING:When loading the roof racks, we recommend you
evenly distribute the load, as well as maintain a low center of
gravity. Loaded vehicles, with higher centers of gravity, may handle
differently than unloaded vehicles. Take extra precautions, such as
slower speeds and increased stopping distance, when driving a heavily
loaded vehicle.
Note:The maximum recommended load, evenly distributed on the
crossbars, is 100 pounds (45 kilograms).
Note:Never place loads directly on the roof panel. The roof panel is not
designed to directly carry a load.

TOWING A TRAILER
WARNING:Do not exceed the GVWR or the GAWR specified on
the certification label.
WARNING:Towing trailers beyond the maximum recommended
gross trailer weight exceeds the limit of your vehicle and could
result in engine damage, transmission damage, structural damage, loss
of vehicle control, vehicle rollover and personal injury.
Note:For information on electrical items such as fuses or relays, see the
Fuseschapter.
The load capacity of your vehicle is designated by weight not volume.
You may not necessarily be able to use all available space when loading
your vehicle or trailer.
Towing a trailer places extra load on the engine, transmission, axle,
brakes, tires, and suspension. Inspect these components before, during
and after towing.
Load Placement
To help minimize how trailer movement affects your vehicle when
driving:
•Load the heaviest items closest to the trailer floor.
•Load the heaviest items centered between the left and right side
trailer tires.
•Load the heaviest items above the trailer axles or just slightly forward
toward the trailer tongue. Do not allow the final trailer tongue weight
to go above or below 10–15% of the loaded trailer weight.
•Select a tow bar with the correct rise or drop. When both the loaded
vehicle and trailer are connected, the trailer frame should be level, or
slightly angled down toward your vehicle, when viewed from the side.
When driving with a trailer or payload, a slight takeoff vibration or
shudder may be present due to the increased payload weight. You can
find more information about proper trailer loading and setting your
vehicle up for towing underLoad limitin theLoad Carryingchapter.
You can also find information in theRV and Trailer Towing Guide
available at your authorized dealer, or online at
http://www.fleet.ford.com/towing-guides.

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 once it
begins.
Note:This feature cannot stop all trailers from swaying.
Note:In some cases, if vehicle speed is too high, the system may turn
on multiple times, gradually reducing vehicle speed.
This feature applies your vehicle brakes at individual wheels and, if
necessary, reduces engine power. If the trailer begins to sway, the
stability control light flashes. The first thing to do is slow your vehicle
down, then pull safely to the side of the road and check for proper
tongue load and trailer load distribution. See theLoad Carryingchapter
for specific loading information.
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 feet
2(1.86 meters2) trailer frontal area if your vehicle can tow a
Class I trailer.
•40 feet
2(3.72 meters2) trailer frontal area 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. Be sure to check state regulations for this specified
weight. The maximum trailer weights listed may be limited to this
specified weight, as your vehicle’s electrical system may not include the
wiring connector needed to use electric trailer brakes.

ESSENTIAL TOWING CHECKS
Follow these guidelines for safe towing:
•Do not tow a trailer until you drive your vehicle at least 1000 miles
(1600 kilometers).
•Consult your local motor vehicle laws for towing a trailer.
•See the instructions included with towing accessories for the proper
installation and adjustment specifications.
•Service your vehicle more frequently if you tow a trailer. See your
scheduled maintenance information.
•If you use a rental trailer, follow the instructions the rental agency
gives you.
For load specification terms found on the tire label and Safety
Compliance label and for instructions on calculating your vehicle’s load,
refer toLoad limitin theLoad Carryingchapter.
Remember to account for the trailer tongue weight as part of your
vehicle load when calculating the total vehicle weight.
Trailer Towing Connector (Vehicles with a Trailer Towing Package
and 7–Pin Connector)
When attaching the trailer wiring connector to
your vehicle, only use a proper fitting connector
that works with the vehicle and trailer functions. If
your vehicle has a trailer towing package, it may
have a 7–pin connector. Some connectors may
have the SAE J2863 logo, which confirms that it is
the proper wiring connector and works correctly
with your vehicle.
