WARNING: This page is about a different car, the 2017 Ford F-550 Super Duty, 2017 Ford F-450 Super Duty, 2017 Ford F-350 Super Duty, and 2017 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: The BLIS ® With Trailer Tow is an extended feature of BLIS ® and depends on the proper functionality of BLIS ®.

NOTE: The transmission needs to be in park (P) in order to select a specific trailer or to input the needed measurements into the IPC message center.

NOTE: The BLIS ® with Trailer Tow only functions with a conventional trailer. If 5th wheel or gooseneck is selected then BLIS ® and CTA functions will turn off.

The BLIS ® with Trailer Tow can be turned off through the IPC message center. If the BLIS ® is turned off, then the BLIS ® with Trailer Tow automatically turns off.

The following steps should be performed when setting up a trailer through the IPC message center:

Select the type of trailer: conventional, 5th wheel or gooseneck. If 5th wheel or gooseneck is selected then BLIS ® and CTA functions will turn off.
Select whether or not the width of the new trailer is less than or equal to 2.6 m (8.5 ft).
Enter the length of the new trailer. The length is measured between the trailer ball hitch and the back of the trailer. BLIS ® with Trailer Tow should turn on and CTA turn off. However, if the trailer length is entered as 3 feet, then CTA remain on (3 feet length is reserved for bike racks and cargo racks).

When the trailer is first connected a message appear in the IPC message center that says "Trailer connected". When connecting to a four pin trailer connector the brake pedal must be depressed immediately afterwards in order to get the "Trailer connected" message. If a preset trailer exists in the IPC then BLIS ® with Trailer Tow automatically receives preset trailer information. If the trailer just connected is not the preset trailer, then select the correct trailer from the IPC menu or add a new trailer with the correct dimensions. If there are no preset trailers in the IPC, then the IPC automatically request trailer information. If at this point the driver exits the message center menus, then BLIS ® and CTA automatically turn off. Otherwise, the driver must add new trailer information through the IPC.

False alerts are possible with a truck and trailer operating with BLIS ® with Trailer Tow. If the ignition is cycled, the BLIS ® with Trailer Tow continues to function using the last trailer selected.

The BLIS ® with Trailer Tow is designed to work with any trailer whose front width is 2.6 m (8.5 ft) or less and the total length from the trailer hitch ball to the rear of the trailer is 10 m (33 ft) or less. Different trailers may cause a slight change in performance as outlined below.

Large box trailers may cause false alerts to trigger when driving next to buildings or near parked cars.
A false alert may also occur while making a 90-degree turns.
Trailers that are 2.6 m (8.5 ft) wide at the front and have a total length greater than 6 m (20 ft) may have delayed alerts from passing vehicles when the vehicle is passing at high speed.
A box trailer whose front width is 2.6 m (8.5 ft) may cause early alerts when over taking a vehicle.
