Some trailers could cause a slight change
in system performance:
Large box trailers could cause false
alerts to occur when driving next to
infrastructures or near parked cars. A
false alert could 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)
could cause delayed alerts when a
vehicle is passing at high speeds.
Box trailers that have a width greater
than 8.5 ft (2.6 m) at the front could
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 could cause delayed alerts
when a vehicle traveling the same
speed as your vehicle merges lanes.
Setting a Trailer Length
You can set-up a trailer to work with the
blind spot information system through the
touchscreen. When setting up a trailer, a
sequence of screens appear asking for
trailer information.
1. Select type of trailer screen -
conventional, fifth wheel or gooseneck.
Note: The system only supports
conventional trailers.
2. Do you want to set up blind spot with
trailer screen? If no, the system turns
off. If yes, the menu goes to the next
screen.
3. Is the width less than 9 ft (2.6 m) and
length less than 33 ft (10.1 m)? If no,
the system turns off. If yes, the menu
goes to the next screen.
4. Trailer width measurement. Measure
the width 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 the system can
support is 9 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 9 ft
(2.6 m) or less.
5. 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).
6. Enter the 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 measure
length is 25 ft (7.5 m), toggle the length
in the menu to 27 ft (8.2 m). The
system setup saves when you enter the
length of the trailer.
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: The system requires proper
measurement and measure entry to function
properly.
Selecting a Trailer
When you connect a trailer to your vehicle,
the trailer set up menu appears in the
touchscreen. 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.
