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.
