Maintenance and Specifications • Four-wheel-drive operation (if equipped) is less fuel efficient than two-wheel-drive operation. • Close windows for high speed driving. EPA window sticker The characteristics of the four wheel drive vehicle, like those of many, similar competitive products, fit within categories where the fuel economy labeling regulations do not apply. Therefore, the following information applies only to the two wheel drive vehicle. Every new vehicle should have the EPA window sticker. Contact your authorized dealer if the window sticker is not supplied with your vehicle. The EPA window sticker should be your guide for the fuel economy comparisons with other vehicles. It is important to note the box in the lower left corner of the window sticker. These numbers represent the range of fuel economy expected on the vehicle under optimum conditions. Your fuel economy may vary depending upon the method of operation and conditions. EMISSION CONTROL SYSTEM Your vehicle is equipped with various emission control components and a catalytic converter which will enable your vehicle to comply with applicable exhaust emission standards. To make sure that the catalytic converter and other emission control components continue to work properly: • Use only the specified fuel listed. • Avoid running out of fuel. • Do not turn off the ignition while your vehicle is moving, especially at high speeds. • Have the items listed in scheduled maintenance information performed according to the specified schedule. The scheduled maintenance items listed in scheduled maintenance information are essential to the life and performance of your vehicle and to its emissions system. If other than Ford, Motorcraft or Ford-authorized parts are used for maintenance replacements or for service of components affecting emission control, such non-Ford parts should be equivalent to genuine Ford Motor Company parts in performance and durability. 370 2006 Navigator (nav) Owners Guide (post-2002-fmt) USA (fus)
