The message center will display "4X4 AUTO" when this position is selected. This is appropriate for all on-road driving conditions, such as dry road surfaces, wet pavement, snow or gravel. • 4H (4X4) provides electronically locked four-wheel drive power to front and rear wheels. The message center will display "4X4" when this position is selected. This position is not recommended for use on dry pavement. This position is only intended for severe winter or off-road conditions, such as deep snow, ice or shallow sand. • 4L (4X4 LOW) provides electronically locked four-wheel drive when extra power at reduced speeds is required. The message center will display "4X4 LOW" when this position is selected. This position is not recommended for use on dry pavement. Use this position for off-road low-speed operation or when extra power is required, such as climbing steep grades, going through deep sand or pulling a boat out of the water. 314 2010 Expedition (exd) Owners Guide, 3rd Printing USA (fus)
