Maintenance and Specifications • Carrying unnecessary weight may reduce fuel economy (as much as 1 mpg [0.4 km/L] is lost for every 400 lb [180 kg] of weight carried). • Adding certain accessories to your vehicle (for example; bug deflectors, rollbars/light bars, running boards, ski/luggage racks) may reduce fuel economy. • Using fuel blended with alcohol may lower fuel economy. • Fuel economy may decrease with lower temperatures during the first 8-10 miles (12-16 km) of driving. • Driving on flat terrain offers improved fuel economy as compared to driving on hilly terrain. • Transmissions give their best fuel economy when operated in the top cruise gear and with steady pressure on the gas pedal. • Four-wheel-drive operation (if equipped) is less fuel efficient than two-wheel-drive operation. • Close windows for high speed driving. EPA window sticker 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. 373 2008 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus)
