FORD 2013 Expedition v.3 - Manual (Page 268)

• The controller interacts with the brake control system and powertrain
control system of your vehicle to provide the best performance on
different road conditions.
• Your vehicle’s brake system and the trailer brake system work
independently of each other. Changing the gain setting on the
controller does not affect the operation of your vehicle’s brakes
whether you attach a trailer or not.
• When you turn the engine off, the controller output is disabled and
the display and module shut down. The controller module and display
turn on when you turn the ignition on.
• The trailer brake controller is only a factory-installed or
dealer-installed item. Ford is not responsible for warranty or
performance of the controller due to misuse or customer installation.
Trailer Lamps
WARNING: Never connect any trailer lamp wiring to the
vehicle’s tail lamp wiring; this may damage the electrical system
resulting in a fire. Contact an authorized dealer as soon as possible for
assistance in proper trailer tow wiring installation. Additional electrical
equipment may be required.
Trailer lamps are required on most towed vehicles. Make sure all running
lights, brake lights, turn signals and hazard lights are working.
Before Towing a Trailer
Practice turning, stopping and backing up to get the feel of your
vehicle-trailer combination before starting on a trip. When turning, make
wider turns so the trailer wheels clear curbs and other obstacles.
When Towing a Trailer
• Do not drive faster than 70 mph (113 km/h) during the first 500 miles
(800 kilometers).
• Do not make full-throttle starts.
• Check your hitch, electrical connections and trailer wheel lug nuts
thoroughly after you have traveled 50 miles (80 kilometers).
• When stopped in congested or heavy traffic during hot weather, place
the gearshift in position P to aid engine and transmission cooling and
to help A/C performance.
• Turn off the speed control with heavy loads or in hilly terrain. The
speed control may turn off automatically when you are towing on
long, steep grades.
