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.
181
Expedition (TB7) Canada/United States of America, enUSA, First Printing Parking Aids

Coverage area of up to 6 ft (1.8 m) from
the rear bumper. There may be decreased
coverage area at the outer corners of the
bumper.
The system detects certain objects while
the transmission is in reverse (R) :
• Your vehicle is moving toward a
stationary object at a speed of
3 mph
(5 km/h) or less.
• Your vehicle is not moving, but a
moving object is approaching the rear
of your vehicle at a speed of
3 mph
(5 km/h) or less.
• Your vehicle is moving at a speed of
less than 3 mph (5 km/h) and a moving
object is approaching the rear of your
vehicle at a speed of less than
3 mph
(5 km/h).
FRONT PARKING AID
The front sensors are active when the
transmission is in any position other than
park (P) and the vehicle speed is below
8 mph (13 km/h)
. Coverage area of up to
28 in (70 cm) from
the front bumper. There is decreased
coverage area at the outer corners.
The system sounds an audible warning
when obstacles are near either bumper in
the following manner:
• Objects detected by the front sensors
are indicated by a high-pitched tone
from the front of the vehicle.
• Objects detected by the rear sensors
are indicated by a lower pitched tone
from the rear of the vehicle.
• The sensing system reports the
obstacle which is closest to the front
or rear of the vehicle. For example, if
an obstacle is
12 in (30 cm) from the
front of the vehicle and, at the same
time, an obstacle is only
6 in (15 cm)
from the rear of the vehicle, the lower
pitched tone sounds.
• An alternating warning sounds from
the front and rear if there are objects
at both bumpers that are closer than
10 in (25 cm)
.

If the system detects a degraded
performance condition, a message warning
of a blocked sensor will appear in the
information display. Also the BLIS alert
indicators will remain ON and BLIS will no
longer provide any vehicle warnings. You
can clear the information display warning
but the alert indicators will remain
illuminated.
A "blocked" condition can be cleared in
two ways:
•
After the blockage in front of the
sensors is removed or the
rainfall/snowfall rate decreases or
stops, drive for a few minutes in traffic
to allow the sensors to detect passing
vehicles.
• By cycling the ignition from ON to OFF
and then back ON.
Note: If your vehicle has a tow bar with a
factory equipped trailer tow module and it
is towing a trailer, the sensors will
automatically turn the Blind Spot
Information System off. If your vehicle has
a tow bar but no factory equipped trailer
tow module, it is recommended to turn the
Blind Spot Information System off
manually. Operating the Blind Spot
Information System with a trailer attached
will cause poor system performance.
System Errors
If the system senses a problem with the
left or right sensor, the telltale will
illuminate and a message will appear in
the information display. See Information
Messages (page 103). Switching the System Off and On
You can temporarily switch the Blind Spot
Information System off in the information
display. See
General Information (page
92). When the Blind Spot Information
System switches off, you will not receive
alerts and the information display shows
a system off message. The telltale in the
cluster also illuminates. When you switch
the Blind Spot Information System on or
off, the alert indicators flash twice.
Note: The Blind Spot Information System
remembers the last selected on or off
setting.
You can also have the Blind Spot
Information System switched off
permanently at an authorized dealer. Once
switched off permanently, the system can
only be switched back on at an authorized
dealer.
CROSS TRAFFIC ALERT WARNING
To help avoid personal injury, NEVER
use the Cross Traffic Alert system as
a replacement for using the interior
and exterior mirrors and looking over your
shoulder before backing out of a parking
space. Cross Traffic Alert is not a
replacement for careful driving. Cross Traffic Alert is designed to warn you
of vehicles approaching from the sides
when the transmission is in reverse (R).
Using the System
Cross Traffic Alert turns on when you start
the engine and you shift into reverse (R).
Once shifted out of reverse (R), Cross
Traffic Alert turns off.
Note:
Cross Traffic Alert only functions
while your transmission is in reverse (R).

Zone coverage also decreases when
parking at shallow angles. Here, the left
sensor is mostly obstructed; zone coverage
on that side is severely limited.
System Lights, Messages and
Audible Alerts
The Cross Traffic Alert illuminates an
amber alert indicator in the outside mirror
on the side of your vehicle the approaching
vehicle is coming from. Cross Traffic Alert
also sounds an audible alert and a
message appears in the information
display indicating a vehicle is coming from
the right or left. Cross Traffic Alert works
with the reverse sensing system that
sounds its own series of tones. See Rear
Parking Aid (page 181). The system uses radar sensors that are
located behind the bumper fascia on each
side of your vehicle. Do not allow mud,
snow or bumper stickers to obstruct these
areas, this can cause degraded system
performance. See Blind Spot
Information System (page 188). If the
Blind Spot Information System is blocked,
Cross Traffic Alert is also blocked. A
corresponding message appears in the
information display as soon as you shift
the transmission into reverse (R).
System Limitations
Cross Traffic Alert has its limitations;
situations such as severe weather
conditions or debris build-up on the sensor
area may limit vehicle detection.
192
Expedition (TB7) Canada/United States of America, enUSA, First Printing Driving AidsE142442 E205199

The following are other situations that may
limit the Cross Traffic Alert performance:
•
Adjacently parked vehicles or objects
obstructing the sensors.
• Approaching vehicles passing at
speeds greater than 37 mph
(60 km/h).
• Driving in reverse faster than
7 mph
(12 km/h).
• Backing out of an angled parking spot.
False Alerts
Note: If your vehicle has a tow bar with a
factory equipped trailer tow module and it
is towing a trailer, the sensors will
automatically turn the Cross Traffic Alert
off. If your vehicle has a tow bar but no
factory equipped trailer tow module, it is
recommended to turn the Cross Traffic Alert
off manually. Operating Cross Traffic Alert
with a trailer attached will cause poor Cross
Traffic Alert performance.
There may be certain instances when there
is a false alert by the Cross Traffic Alert
system that illuminates the alert indicator
with no vehicle in the coverage zone. Some
amount of false alerts are normal; they are
temporary and self-correct.
System Errors
If Cross Traffic Alert senses a problem with
the left or right sensor a message will
appear in the information display. See
Information Messages
(page 103).
Switching the System Off and On
You can temporarily switch Cross Traffic
Alert off in the information display. See
General Information
(page 92). When
you switch Cross Traffic Alert off, you will
not receive alerts and the information
display will display a system off message. Note:
The Cross Traffic Alert switches on
whenever the ignition is switched on and
ready to provide appropriate alerts when
the transmission is in reverse (R). Cross
Traffic Alert will not remember the last
selected on or off setting.
You can also have Cross Traffic Alert
switched off permanently at an authorized
dealer. Once switched off permanently,
the system can only be switched back on
at an authorized dealer.
STEERING
Electric Power Steering WARNINGS
The electric power steering system
has diagnostic checks that
continuously monitor the system. If
a fault is detected, a message displays in
the information display. Stop your vehicle
as soon as it is safe to do so. Switch the
ignition off. After at least 10 seconds,
switch the ignition on and watch the
information display for a steering system
warning message. If a steering system
warning message returns, have the system
checked by an authorized dealer. If the system detects an error, you
may not feel a difference in the
steering, however a serious condition
may exist. Obtain immediate service from
an authorized dealer, failure to do so may
result in loss of steering control. Your vehicle has an electric power steering
system. There is no fluid reservoir. No
maintenance is required.
If your vehicle loses electrical power while
you are driving, electric power steering
assistance is lost. The steering system still
operates and you can steer your vehicle
manually. Manually steering your vehicle
requires more effort.
