Maintenance and Care s Keep the tires properly inflated. To find out the recommended tire pressure, see Checking the pressure of the tires later in this chapter. s 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: s Use only unleaded fuel. s Avoid running out of fuel. s Never turn off the ignition while your vehicle is moving, especially at high speeds. s 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. 307
