• The TBC interacts with the brake system of the vehicle, including

ABS, in order to reduce the likelihood of trailer wheel lockup.

Therefore, if these systems are not functioning properly the TBC may

not function at full performance.

• When the vehicle is turned off, the TBC Output is disabled and the

display is shut down. Reactivation of the ignition from OFF to ON will

awaken the TBC module.

• The TBC is only a factory or dealer installed item. Ford is not

responsible for warranty or performance of the TBC due to misuse or

customer installation.

• Do not attempt removal of the TBC without consulting the

Workshop Manual. Damage to the unit may result.

Trailer lamps

Trailer lamps are required on most towed vehicles. Make sure all running

lights, brake lights, turn signals and hazard lights are working. Contact

your authorized dealer or trailer rental agency for proper instructions

and equipment for hooking up trailer lamps.

Driving while you tow

When towing a trailer:

• Do not drive faster than 70 mph (113 km/h) during the first 500 miles

(800 km) of trailer towing and don’t make full-throttle starts.

• Turn off the speed control. The speed control may shut off

automatically when you are towing on long, steep grades.

• Consult your local motor vehicle speed regulations for towing a trailer.

• To eliminate excessive transmission shifting, activate the Tow/Haul

feature. This will also assist in transmission cooling. For additional

information, refer to Automatic transmission operation in the

Driving chapter.

• Anticipate stops and brake gradually.

• Do not exceed the GCWR rating or transmission damage may occur.

• Your vehicle may be equipped with a temporary or conventional spare

tire. If the spare tire is different in size (diameter and/or width), tread

type (All-Season or All-Terrain) or is from a different manufacturer

other than the road tires on your vehicle, your spare tire is considered

“temporary”. Consult information on the spare Tire Label or Safety

Compliance Certification Label for limitations when using.
