Ford 1997 Aerostar Manual page 269

Do not park, idle, or drive your vehicle in
dry grass or other dry ground cover. The
emission system heats up the engine
compartment and exhaust system, which
can start a fire.
On vehicles without original equipment
floor covering or insulation, do not let
passengers ride in your truck in a manner
that allows contact between skin and the
metal floor.
Watch for fluid leaks, strange odors, smoke, loss
of oil pressure, the charge warning light, the
check engine light, or the temperature warning
light. These sometimes indicate that the emission
system is not working properly.
Do not make any unauthorized changes to your
vehicle or engine. Changes that cause more
unburned fuel to reach the exhaust system can
increase the temperature of the engine or
exhaust system.
By law, anyone who manufactures, repairs,
services, sells, leases, trades vehicles, or
supervises a fleet of vehicles is not permitted to
intentionally remove an emission control device
or prevent it from working. In some of the
United States and in Canada, vehicle owners
may be liable if their emission control device is
removed or is prevented from working.
Never use a metal exhaust collector when you
service your vehicle. If the metal collector
contacts any of your vehicle's plastic trim or
bumper parts they could melt or deform.
