For maximum vehicle performance, keep the following information in
mind when adding accessories or equipment to your vehicle:
•When adding accessories, equipment, passengers and luggage to your
vehicle, do not exceed the total weight capacity of the vehicle or of
the front or rear axle (GVWR or GAWR as indicated on the Safety
compliance certification label). Consult your dealer for specific weight
information.
•The Federal Communications Commission (FCC) and Canadian Radio
Telecommunications Commission (CRTC) regulate the use of mobile
communications systems - such as two-way radios, telephones and
theft alarms - that are equipped with radio transmitters. Any such
equipment installed in your vehicle should comply with FCC or CRTC
regulations and should be installed only by a qualified service
technician.
•Mobile communications systems may harm the operation of your
vehicle, particularly if they are not properly designed for automotive
use or are not properly installed. When operated, such systems may
cause the engine to stumble or stall or cause the transmission to be
damaged or operate improperly. In addition, such systems may be
damaged or their performance may be affected by operating your
vehicle. (Citizens band [CB] transceivers, garage door openers and
other transmitters with outputs of five watts or less will not ordinarily
affect your vehicle’s operation.)
•Ford cannot assume responsibility for any adverse effects or damage
that may result from the use of such equipment.
