NOTE: Mobile communication systems, particularly if not
properly installed, may adversely affect the operation
of the vehicle. For example, such systems, when operated,
may cause the engine to stumble or stall. In addition,
such systems may themselves be damaged, or their
operation affected, by the operation of the vehicle.
(Citizens band [CB] transceivers, garage door openers,
and other transmitters whose power output is 5
watts or less, ordinarily will not affect vehicle operation.)
NOTE: Because Ford has no control over the operation or
manufacture of such systems or their installation, Ford
cannot assume responsibility for any adverse effects
or damage if this equipment is used.
