Trailer width measurement:
The width of the trailer is measured at the
front of the trailer. It is not measured at the
widest point of the trailer. The maximum
width at the front of the trailer that the
system can support is 8.5 ft (2.6 m).
Note: You do not need to enter an exact
trailer width measurement. You only need
to confirm that the width of the trailer is
8.5 ft (2.6 m)
or less.
• Trailer length measurement:
The trailer length is the distance between
the trailer hitch ball and the rear of the
trailer. The maximum length that the
system can support is
33 ft (10.1 m).
• Enter length of trailer:
The default setting is
18 ft (5.5 m).
Toggling up or down using the menu
buttons increases or decreases the
measurement by
3 ft (1 m). Select a length
that is equal to or within 3 ft (1 m) of the
actual measured length. For example, if
the actual measured length is 25 ft (7.6 m),
toggle the length in the menu to
27 ft
(8.2 m). When you enter the length of the
trailer, the system setup is saved.
Note: If the trailer is a bike rack or cargo
rack with electrical lighting, enter a length
of
3 ft (1 m). Cross Traffic Alert remains on
for trailers with a length of 3 ft (1 m) or less.
Note: Proper measurement and
measurement entry is required for the
system to function as designed.
System Operation
When you connect a trailer to your vehicle,
the trailer set up menu appears in the
information display. This menu allows you
to set up a new trailer or choose from a
previously set up trailer. A warning
message appears and the system turns off
if you do not choose or add a new trailer. Note:
The warning message may not
appear until your vehicle speed reaches
22 mph (35 km/h)
.
If you select a trailer in the information
display before connecting a trailer to your
vehicle, the system loads the configuration
for the selected trailer. When a trailer is
connected, a warning message appears.
Note: A second warning message may
appear stating that the Cross Traffic Alert
system has turned off. The Blind Spot
Information System with Trailer Tow
continues to function normally in this
situation.
Note: The system remembers the last
selected trailer set up when you start your
vehicle.
Trailer Considerations
The system is designed to work with a
trailer with a front width of
8.5 ft (2.6 m)
or less, and a total length from the trailer
hitch ball to the rear of the trailer of
33 ft
(10.1 m) or less.
Some trailers may cause a slight change
in system performance:
• Large box trailers may cause false
alerts to occur when driving next to
infrastructures or near parked cars. A
false alert may also occur while making
a 90 degree turn.
• Trailers that have a width greater than
8.5 ft (2.6 m)
at the front and have a
total length greater than 20 ft (6 m)
may cause delayed alerts when a
vehicle is passing at high speeds.
262
Expedition (TB8) Canada/United States of America, enUSA, First-Printing Driving Aids

•
Box trailers that have a width greater
than 8.5 ft (2.6 m) at the front may
cause early alerts when you pass a
vehicle.
• Clam shell or V-Nose box trailers with
a width greater than
8.5 ft (2.6 m) at
the front may cause delayed alerts
when a vehicle traveling the same
speed as your vehicle merges lanes.

approaching from the sides behind your
vehicle when you shift into reverse (R).
Using Cross Traffic Alert
The system detects vehicles that approach
at a speed between
4 mph (6 km/h) and
37 mph (60 km/h). Coverage decreases
when the sensors are partially, mostly or
fully obstructed. Slowly reversing helps
increase the coverage area and
effectiveness.

engine and you shift into reverse (R). The
system turns off when you shift out of
reverse (R).
263
Expedition (TB8) Canada/United States of America, enUSA, First-Printing Driving Aids

Zone coverage also decreases when
parking at narrow angles. The sensor on
the left-hand side is mostly obstructed and
zone coverage on that side is severely
reduced.
Cross Traffic Alert System Sensors
The sensors are behind the rear bumper
on both sides of your vehicle.
Note:
Keep the sensors free from snow, ice
and large accumulations of dirt.
Note: Do not cover the sensors with bumper
stickers, repair compound or other objects.
Note: Blocked sensors could affect system
performance.
If the sensors are blocked, a message may
appear in the information display when
you shift into reverse (R).
Cross Traffic Alert System
Limitations
The system may not correctly operate
when any of the following occur:
• The sensors are blocked.
