USING HILL DESCENT
CONTROL
Principle of Operation
WARNINGS
Hill descent control cannot control
descent in all surface conditions and
circumstances, such as ice or
extremely steep grades. Hill descent
control is a driver assist system and cannot
substitute for good judgment by the driver.
Failure to do so may result in loss of vehicle
control, crash or serious injury. Hill descent control does not provide
hill hold at 0 mph (0 km/h). When
stopped, the parking brake must be
applied or the vehicle must be placed in
park (P) or it may roll away. Hill descent control allows the driver to set
and maintain vehicle speed while
descending steep grades in various surface
conditions.
Hill descent control can maintain vehicle
speeds on downhill grades between 3 mph
(5 km/h)
and 20 mph (32 km/h). Above
20 mph (32 km/h), the system remains
armed, but descent speed cannot be set
or maintained. Hill descent control requires a cooling
down interval after sustained use. The
amount of time that the feature can
remain active before cooling varies with
conditions. The system provides a warning
in the message center and a chime sounds
when the system is about to disengage for
cooling. At this time, manually apply the
brakes to maintain descent speed.
Using Hill Descent Control Press and release the hill
descent button in the center of
the terrain management control.
The button illuminates and a chime sounds
when you switch this feature on.
To increase descent speed, press the
accelerator pedal until you reach the
desired speed. To decrease descent
speed, press the brake pedal until you
reach the desired speed.
Whether accelerating or decelerating, once
you reach the desired descent speed,
remove your feet from the pedals and hill
descent control maintains the chosen
vehicle speed.
Note: You may observe noise from the ABS
pump motor during hill descent control
operation. This is a normal characteristic of
the ABS and should be no reason for
concern.

PRINCIPLE OF OPERATION
WARNINGS
To help avoid personal injury, please
read and understand the limitations
of the system as contained in this
section. Sensing is only an aid for some
(generally large and fixed) objects when
moving on a flat surface at parking speeds.
Certain objects with surfaces that absorb
ultrasonic waves, surrounding vehicle's
parking aid systems, traffic control
systems, fluorescent lamps, inclement
weather, air brakes, and external motors
and fans may also affect the function of
the sensing system; this may include
reduced performance or a false activation. To help avoid personal injury, always
use caution when in reverse (R) and
when using the sensing system.
This system is not designed to
prevent contact with small or moving
objects. The system is designed to
provide a warning to assist the driver in
detecting large stationary objects to avoid
damaging your vehicle. The system may
not detect smaller objects, particularly
those close to the ground. Certain add-on devices such as large
trailer hitches, bike or surfboard racks
and any device that may block the
normal detection zone of the system, may
create false beeps. Note:
Keep the sensors, located on the
bumper or fascia, free from snow, ice and
large accumulations of dirt. If the sensors
are covered, the system ’s accuracy can be
affected. Do not clean the sensors with
sharp objects.
Note: If your vehicle sustains damage to
the bumper or fascia, leaving it misaligned
or bent, the sensing zone may be altered
causing inaccurate measurement of
obstacles or false alarms. Note:
The sensing system cannot be turned
off when a MyKey is present. See Principle
of Operation (page 46).
Note: If you attach certain add-on devices
such as a trailer or bike rack, the rear sensing
system may detect that add-on device and
therefore provide warnings. It is suggested
that you disable the rear sensing system
when you attach an add-on device to your
vehicle to prevent these warnings.
The sensing system warns the driver of
obstacles within a certain range of your
vehicle. The system turns on automatically
whenever you switch the ignition on.
The system can be switched off through
the information display menu or from the
pop-up message that appears once you
shift the transmission into reverse (R). See
General Information
(page 92).
Note: On vehicles with front parking aid you
can use the parking aid switch to switch the
system off.
If a fault is present in the system, a warning
message appears in the information
display. See
Information Messages
(page 103).
REAR PARKING AID
The rear sensors are only active when the
transmission is in reverse (R). As your
vehicle moves closer to the obstacle, the
rate of the audible warning increases.
When the obstacle is less than
10 in
(25 cm) away, the warning sounds
continuously. If the system detects a
stationary or receding object farther than
10 in (25 cm)
from the corners of the
bumper, the tone sounds for only three
seconds. Once the system detects an
object approaching, the warning sounds
again.

PRINCIPLE OF OPERATION
Cruise control lets you maintain a set
speed without keeping your foot on the
accelerator pedal. You can use cruise
control when your vehicle speed is greater
than 20 mph (30 km/h).
USING CRUISE CONTROL WARNINGS
Do not use cruise control on winding
roads, in heavy traffic or when the
road surface is slippery. This could
result in loss of vehicle control, serious
injury or death. When you are going downhill, your
vehicle speed may increase above
the set speed. The system will not
apply the brakes but a warning displays.
Failure to follow this warning could result
in serious personal injury or death. Note:
Cruise control will disengage if the
vehicle speed decreases more than 10 mph
(16 km/h) below the set speed while driving
uphill. The cruise controls are on the steering
wheel.

Extreme continuous steering may increase
the effort required for you to steer your
vehicle. This increased effort prevents
overheating and permanent damage to
the steering system. You do not lose the
ability to steer your vehicle manually.
Typical steering and driving maneuvers
allow the system to cool and return to
normal operation.
Steering Tips
If the steering wanders or pulls, check for:
•
Correct tire pressures.
• Uneven tire wear.
• Loose or worn suspension
components.
• Loose or worn steering components.
• Improper vehicle alignment.
Note: A high crown in the road or high
crosswinds may also make the steering
seem to wander or pull.
Adaptive Learning
The electronic power steering system
adaptive learning helps correct road
irregularities and improves overall handling
and steering feel. It communicates with
the brake system to help operate
advanced stability control and accident
avoidance systems. Additionally, whenever
the battery is disconnected or a new
battery installed, you must drive your
vehicle a short distance before the system
relearns the strategy and reactivates all
systems. DRIVE CONTROL
Driver Select Suspension
Driver select suspension delivers a unique
driving experience through a suite of
sophisticated electronic vehicle systems.
These systems continuously monitor your
driving inputs and the road conditions to
optimize ride comfort, steering and
handling.
Driver select suspension consists of the
following systems:
•
Continuously controlled damping
dynamically adjusts the shock
absorbers stiffness in real time to
match the road surface and driver
inputs. This system continuously
monitors your vehicle ’s motion (roll,
pitch, bounce), suspension position,
load, speed, road conditions, and
steering to adjust the suspension
damping for optimal vehicle control.
• Electronically power-assisted steering
adjusts steering effort and feel based
on your vehicle speed and your inputs.
The configuration remains active until
modified from the main menu on the
information display. See General
Information (page 92).

GCW (Gross Combined Weight)
- is the Gross Vehicle Weight plus
the weight of the fully loaded
trailer.
GCWR (Gross Combined
Weight Rating) - is the maximum
allowable weight of the vehicle
and the loaded trailer, including
all cargo and passengers, that the
vehicle can handle without risking
damage. (Important: The towing
vehicle ’s braking system is rated
for operation at Gross Vehicle
Weight Rating, not at Gross
Combined Weight Rating.)
Separate functional brakes should
be used for safe control of towed
vehicles and for trailers where the
Gross Combined Weight of the
towing vehicle plus the trailer
exceed the Gross Vehicle Weight
Rating of the towing vehicle. The
Gross Combined Weight must
never exceed the Gross
Combined Weight Rating.
Maximum Loaded Trailer
Weight -
is the highest possible
weight of a fully loaded trailer the
vehicle can tow. It assumes a
vehicle with mandatory options,
driver and front passenger weight
(150 pounds [68 kilograms]
each), no cargo weight (internal
or external) and a tongue load of
10– 15% (conventional trailer) or
king pin weight of 15– 25% (fifth
wheel trailer). Consult an
authorized dealer (or the RV and
Trailer Towing Guide available at
an authorized dealer) for more
detailed information. Tongue Load or Fifth Wheel
King Pin Weight -
refers to the
amount of the weight that a trailer
pushes down on a trailer hitch.
Examples:
For a 5000 pound
(2268 kilogram) conventional
trailer, multiply 5000 by 0.10 and
0.15 to obtain a proper tongue
load range of 500 to 750 pounds
(227 to 340 kilograms). For an
11500 pound (5216 kilogram) fifth
wheel trailer, multiply by 0.15 and
0.25 to obtain a proper king pin
load range of 1725 to 2875 pounds
(782 to 1304 kilograms). WARNINGS
Do not exceed the GVWR or
the GAWR specified on the
Safety Compliance Certification
Label. Do not use replacement tires
with lower load carrying
capacities than the original tires
because they may lower the
vehicle ’s GVWR and GAWR
limitations. Replacement tires
with a higher limit than the original
tires do not increase the GVWR
and GAWR limitations. Exceeding any vehicle weight
rating limitation could result
in serious damage to the vehicle
and/or personal injury. Steps for determining the
correct load limit:

TOWING A TRAILER
WARNINGS
Do not exceed the GVWR or
the GAWR specified on the
certification label. Towing trailers beyond the
maximum recommended
gross trailer weight exceeds the
limit of the vehicle and could
result in engine damage,
transmission damage, structural
damage, loss of vehicle control,
vehicle rollover and personal
injury. Your vehicle may have electrical
items, such as fuses or relays,
related to towing. See the Fuses
chapter.
Your vehicle's load capacity
designation is by weight, not by
volume, so you cannot necessarily
use all available space when
loading a vehicle or trailer.
Towing a trailer places an extra
load on your vehicle's engine,
transmission, axle, brakes, tires
and suspension. Inspect these
components periodically during,
and after, any towing operation. 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.
Additional information regarding
proper trailer loading and setting
your vehicle up for towing is
located in another chapter of this
manual. See
Load Limit (page
198).
You can also find information in
the
RV & Trailer Towing Guide
available at your authorized
dealer, or online.

TRAILER SWAY CONTROL 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 activate 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 and the
message TRAILER SWAY REDUCE
SPEED appears in the information display.
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
Load
Carrying (page 196). 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 36.5 feet²
(3.39 meters²) if your vehicle is equipped
with the standard towing package, or 60
feet² (5.57 meters²) if your vehicle is
equipped with the optional heavy duty
package.
Note: Exceeding this limitation may
significantly reduce the performance of your
towing vehicle. Selecting a trailer with a low
aerodynamic drag and rounded front design
helps optimize performance and fuel
economy.
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 the vehicle ’s electrical
system may not include the wiring
connector needed to activate electric trailer
brakes.
Your vehicle may tow a trailer provided the
maximum trailer weight is less than or
equal to the maximum trailer weight listed
for your vehicle configuration on the
following chart.
206
Expedition (TB7) Canada/United States of America, enUSA, First Printing Towing

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.
See Load limits in the Load Carrying
chapter for load specification terms found
on the tire label and Safety Compliance
label and instructions on calculating your
vehicle's load.
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. Some seven-position
connectors may have the SAE J2863 logo,
which confirms that it is the proper wiring
connector and works correctly with your
vehicle.
