Driving 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. Note: If your vehicle is equipped with AdvanceTrac௡ with RSC௡, the AdvanceTrac௡ with RSC௡ system will automatically turn off the stability enhancement feature when you shift the Control Trac four-wheel drive system into 4L (4X4 LOW). The brake traction enhancement feature will still be enabled. The AdvanceTrac௡ with RSC௡ stability enhancement system can be turned off manually by pressing the AdvanceTrac௡ with RSC௡ button (refer to AdvanceTrac௡ with Roll Stability Control™ (RSC௡) Stability Enhancement System in this chapter) while operating in 2H, 4A or 4H while driving in deep sand, very deep snow or more strenuous off-road maneuvers. This will disable the engine management feature, allowing the vehicle to maintain full power and enhanced momentum through the obstacle. WARNING: Utility and four-wheel drive vehicles are not designed for cornering at speeds as high as passenger cars any more than low-slung sports cars are designed to perform satisfactorily under off-road conditions. Avoid sharp turns or abrupt maneuvers in these vehicles. Note: The Control Trac selector knob should not be changed while the rear wheels are slipping. Shifting between modes Shifting between 2H and 4A or 4H Move the control from 2H to the 4A or 4H position at any forward speed or at a stop. The message center may display 4X4 SHIFT IN PROGRESS during the system shift. The message center will then display "4X4 AUTO" if 4A is selected or "4X4" if 4H is selected. The message center will momentarily display Љ4X2Љ if 2H is selected. 314 2010 Expedition (exd) Owners Guide (own2002), 1st Printing USA (fus)
