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 you connect
a trailer, 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 speed.

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.
System Errors
If the system detects a fault, a warning
lamp illuminates and a message displays.
See Information Messages (page 123).
Switching the System On and Off
You can switch the system off using the
information display. See General
Information (page 112). When you switch
the system off, a warning lamp illuminates
and a message displays. When you switch
the system on or off, the alert indicators
flash twice.
Note: The system remembers the last
setting when you start your vehicle.
Note: The system may not correctly operate
when towing a trailer. For vehicles with an
approved trailer tow module and tow bar,
the system turns off when you attach a
trailer. For vehicles with an aftermarket
trailer tow module or tow bar, we
recommend that you switch the system off
when you attach a trailer.
To permanently switch the system off,
contact an authorized dealer.
