Ford Econoline/Club Wagon E-150 Owner's Manual page 69

Have the exhaust and body ventilation systems
checked whenever:
your vehicle is raised for service
the sound of the exhaust system changes
your vehicle has been damaged in a collision
Improve your ventilation by keeping all air inlet
vents clear of snow, leaves, and other debris.
If the engine is idling while you are stopped in
an open area for long periods of time, open the
windows at least one inch (2.5 cm). Also, adjust
the heating or air conditioning to bring in
outside air.
HEATING — Set fan speed on MEDIUM or
HIGH, with the function control lever on
FLOOR, DEFROST or VENT and the
temperature control lever on any desired
position.
AIR CONDITIONING — Set fan speed on
MEDIUM or HIGH with the function control
lever on any position (except OFF or MAX)
and the temperature control lever at a
comfortable level.
