PRINCIPLE OF OPERATION
WARNING: 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 allows you to set and
maintain vehicle speed when descending
steep grades in various surface conditions.
Hill descent control can maintain vehicle
speeds on downhill grades between
0 mph
(3 km/h) and 20 mph (32 km/h). Above
20 mph (32 km/h), the system remains
armed, but you cannot use the system to
set or maintain the descent speed.
Hill descent control requires a cooling
down interval after a period of 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 tone
sounds when the system is about to
disengage for cooling. At this time,
manually apply the brakes as needed to
maintain descent speed.
USING HILL DESCENT
CONTROL Press and release the hill
descent button on the
instrument panel. 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.
Hill Descent Modes

2 mph (3 km/h)
and 20 mph (32 km/h): When you
press this button, the light flashes
indicating this feature is active. Your
vehicle maintains the speed you desire
while in this mode.
• At speeds between
20 mph (32 km/h)
and 40 mph (64 km/h): When you
press this button, the light is solid and
a message appears in the information
display indicating this feature is active.
Your vehicle does not maintain the
speed you desire and you cannot set
your descent speed.
• At speeds above
40 mph (64 km/h):
When you press this button, the system
turns this feature off and no light or
message appears in the information
display. You need to switch this feature
back on to use.

PRINCIPLE OF OPERATION
WARNING: To help avoid personal
injury, always use caution when in
reverse (R) and when using the sensing
system. WARNING:
The system may not
detect objects with surfaces that absorb
reflection. Always drive with due care
and attention. Failure to take care may
result in a crash. WARNING: Traffic control systems,
inclement weather, air brakes, external
motors and fans may affect the correct
operation of the sensing system.This
may cause reduced performance or false
alerts. WARNING:
The system may not
detect small or moving objects,
particularly those close to the ground.
Note: Certain add-on devices installed
around the bumper or fascia may create
false beeps. For example, large trailer
hitches, bike or surfboard racks, license plate
brackets, bumper covers or any other device
that may block the normal detection zone
of the system.
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. See your
authorized technician. Note:
When a trailer is connected to your
vehicle, the rear parking aid may detect the
trailer and therefore provide warnings.
Disable the rear parking aid when a trailer
is connected to prevent these warnings.
Note: The sensing system cannot be turned
off when a MyKey is present. See Principle
of Operation
(page 68).
We recommend that you take some time
to get to know the system and its
limitations by reading this section.
The sensing system warns the driver of
obstacles within a certain range of your
vehicle. The system automatically turns
on each time you switch the ignition on.
When receiving a detection warning, the
radio volume reduces to a predetermined
level. After the warning goes away, the
radio volume returns to the previous level. You can turn the system on or
off by pressing the parking aid
button. If your vehicle does not
have a parking aid button, 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 119).
If a fault is present in the system, a warning
message appears in the information
display and does not allow you to switch
the system on. See
Information
Messages (page 129).
If a sensor is blocked and cannot function,
the system becomes disabled and a
warning message appears in the
information display. The system returns to
a normal state once the blockage is
cleared.

Expedition (TB8) Canada/United States of America, enUSA, First-Printing Parking AidsE139213

The system uses three types of guides to
help you see what is behind your vehicle:
•
Active guidelines (if equipped): Show
the intended path of your vehicle when
reversing.
• Fixed guidelines: Show the actual path
your vehicle is moving in while reversing
in a straight line. This can be helpful
when backing into a parking space or
aligning your vehicle with another
object behind you.
• Centerline: Helps align the center of
your vehicle with an object. For
example, a trailer.
Note: If the transmission is in reverse (R)
and the luggage compartment door or
liftgate is open, no rear view camera
features display.
Note: When towing, the camera only sees
what you are towing. This might not provide
adequate coverage as it usually provides in
normal operation and some objects might
not be seen. In some vehicles, the guidelines
may disappear when you connect the trailer
tow connector.
The camera may not operate correctly
under the following conditions:
• Nighttime or dark areas if one or both
reverse lamps are not operating.
• Mud, water or debris obstructs the
camera's view. Clean the lens with a
soft, lint-free cloth and non-abrasive
cleaner. The rear view camera has a
washer that activates when you use
the rear window washer. See Rear
Window Wiper and Washers (page
97).
• The rear of your vehicle is hit or
damaged, causing the camera to
become misaligned. Camera System Settings
