Emission Control System - Ford Windstar Owner's Manual

Keep the tires properly inflated. To find out the
recommended tire pressure, see Checking the pressure of the
tires later in this chapter.
Use your air conditioning system wisely. To find out about
fuel economy and air conditioning, see Climate control systems
in the Index.
In addition to your individual driving habits, optional
equipment, such as air conditioning, can have a significant effect
on fuel economy. Various aftermarket add-on items that increase
aerodynamic drag can also reduce fuel economy.

Emission Control System

Your vehicle is equipped with a catalytic converter which
enables your vehicle to comply with applicable exhaust emission
requirements.
To make sure that the catalytic converter and the other emission
control parts continue to work properly:
Use only unleaded fuel.
Avoid running out of fuel.
Never turn off the ignition while your vehicle is moving,
especially at high speeds.
Have the services listed in your Maintenance Schedule booklet
performed according to the specified schedule. The scheduled
maintenance services are required because they are
considered essential to the life and performance of your
vehicle and to its emission system.
